A：What is "nanometer"?
Nanometer (symbol is nm), also known as nm, it is just like centimeter, decimeter and meter, it is a measure of length.1 nanometer is equal to 1/1000000000 of 1 meter.The diameter of a person's hair is about 60-70 thousand nanometers, that is, 1 nanometer is equivalent to 1/10000 of a hair.
   Thus,nanometeris a tiny size. Graphically speaking, if an 1 nanometer object is placed on a table tUNICS ball, it is just like a table tUNICS ball is placed on the earth. This is the concept of nanometer length.
  When traditional solid materials are refined to the nanometer level through scientific and technological means, the surface and quantum tunnel effects caused by the changes in the structure and energy state, it produces many unique physical, chemical, and other physiological properties such as light, electricity, magnetism, and mechanics, and it has extremely high activity.

 

B：What is negative ion?
Negative ions refer to particles with negative electronegativity. For example, the particles with positive electricity in the air are called positive ions, and the negative particles are called negative ions. And ions are atoms that float in the air with electrons.
Experiments show that negatively charged air molecules combine with tiny water molecules to form negative ions. After breathing into the blood, it can enhance the metabolism of human body. This is the reason why the waterfalls and forests are so refreshing. Negative ions are often used to clean the air, and living in a room filled with negative oxygen ions can make people feel happy. Professor Tazawa Kenji, Toyama Medical University recently discovered that negative oxygen ions can also increase antioxidant in human body and reduce the harm of reactive oxygen species to human body.

Home decoration pollution
Furniture, floor, and paint will release formaldehyde, benzene and other chemical gases, stimulating people's features, causing tears, coughing, sneezing and other conditions. Poorly immune elderly and children are more likely to cause respiratory and blood diseases.

Bacterial contamination
Central air-conditioning ventilation ducts, home textiles, and pet hair are all hotbeds of bacterial growth and can easily cause respiratory diseases.

Air pollution
The radiation of high-voltage power lines, exhaust emissions from automobiles, dust storm, the fog, and polluting gases emitted from factories are constantly jeopardizing our health.

Hypoxia pollution

The warming of the earth's climate has caused severe seasonal polarization. Air-conditioning is used frequently in winter and summer, ventilation is insufficient, and air conditioning disease is common, results in indoor oxygen deficiency. The increase in the concentration of carbonic acid in human blood results in inadequate blood supply to the brain and chest tightness and headache.

Technical specifications for internal wall construction:
One of the prominent problems encountered in the construction of inner wall is the temperature, relative humidity and water content of the construction site.If the wall surface temperature is lower than 5 ℃, the relative temperature is higher than 85% and the water content is higher than 10%, the paint film strength of the wall surface will be affected, and many construction problems are produced.

 

Preparations before construction
The preparation of the base surface is very important. It is the key to determine the actual effect of the paint surfaceafter the painting. The following steps must be done:
Remove the wall spalling and floating of the old paint or coating, oil, dust and mildew. The work needs to be taken with protective glasses and gloves.

Scraping the walls, fill all holes, cracks and rough surface.
●Grinding the bump and rough surface with sand paper to make the wall surface smooth and remove the dust on the surface.
●Use a mild cleaning agent or water to clean the surface of the wall and make it dry.
●After the wall is dry, paint the primer.
●It is recommended that use the wall corner junction or downspout as the boundary, cross-brushing is performed from the center to the top, bottom, left, and right. Even the material on the roller is completely brushed and the area is completely covered. In the end, gently roll in one direction to obtain the same refractive index.The same method of painting can be used for the second time painting, with the wet area of the first brushing area, in order to avoid overlapping seams, repeat the above steps until the wall is washed.
●After the interior wall primer is completely dry, it should completely cover the wall surface and there should be no scratching phenomenon. This shows that the primer construction has reached the requirements. Otherwise, it indicates that the roller is too thin or uneven when rolled.
●After the general primer is dry, the top coating can be painted.Try to avoid construction in the weather of high humidity, so as to avoid various construction problems and affect the quality.
●When applying latex paint, good ventilation must be maintained. Especially when using some volatile floor paints and furniture paints, if the ventilation conditions are not good, the volatile gas in the paint can make the latex paint color yellowed. The best construction step is to brush the floor paint, furniture paint, and apply latex paint after the volatile gas has evaporated.
●If latex paint is applied first, the latexpaint must be fully dried before oil paint is applied. At the same time, the doors and windows should be opened when painting. The ventilation should be maintained for more than 24 hours after the construction is completed.
●Generally, it is not advisable to work in environments where the room temperature is below 5°C so as not to affect the strength of the paint film.

● If you choose to change color of the coating, in order to ensure the same color after painting, the general method is to fully mix the same color paint in advance, stir evenly, and construct for one time.

 

Construction methods      
Whenroller is used in the construction, use high quality roller as much as possible. The bad roller not only has uneven rolling brush, but also leave some roller print and roller fiber on the wall, and we can also use a spray gun for construction. Although it consumes a lot of material, it will get a better paint effect and greatly improve the construction efficiency.

 The primer of the inner wall latex paint should be diluted properly. Excessive dilution will lead to the appearance of the powder film, and affect the texture of the film, the scrubbing and covering effect.Before using the roller,it is necessary to paint the wall corner with a brush, and then use a roller for large areas.

 

Construction deploymet 

According to the characteristics of each project, the construction stage of the project is scientifically divided into the following stages. According to the construction characteristics of each stage, advanced technology is applied to organize and deploy the construction:
1. Construction preparation period
2.Base surface treatment period
3.Primer painting period
4.Top coat brushing period
5. Pre-acceptance period

For each of the above construction stages, and with the overall progress of the construction plan and project quality, safety assurance measures, we make the development of the various stages respectively, and we will have quality and other guarantee measures for consumers, in order to dynamically control the construction of all stages.

When the team leaders perform construction tasks, they must be fully managed to eliminate common defects and eliminate errors and omissions. They must negotiate with the construction staff according to the actual situation on the site, and the regulations must not be apply mechanically.
The implementation of the three level quality control system, that is, the construction team leader, the constructor, the qualityinspector each does his duty, the construction team leader carries out the responsibility, the constructor, the quality inspector has the negative supervision and the inspection responsibility.
Field tracking to ensure quality. The constructors and qualityinspectors should check the whole quality of the construction. From the base surface treatment to the last finishing painting, a careful inspectionmust be done,and find out the problems in time.

Schedule assurance

The completion of the project is the most basic requirement of engineering construction. The implementation of the project duration involves many factors. In the whole process of construction, the key factors influencing the duration of the project and making reasonable countermeasures are the key to the successful completion of the project.In order that the project can be completed at the specified time, the following measures will be taken:

1、Unified organization and deployment, and do a good job in construction coordination.The engineering project manage department will act as a command organization, through unified command, careful planning and timely adjustment of construction plan, so that the whole project plan and construction will be highlighted. The construction is orderly, the schedule is balanced and reasonable, and the overall construction plan is ensured.
2、Cooperate with the civil construction, installation and decoration units.Coating decoration is the last link of architectural decoration, and how to grasp the rhythm of painting construction on the basis of civil construction and installation and decoration units, so as to achieve the coordination with installation,decoration and construction.To do a good job and reduce unnecessary rework is the most critical measure for the coating construction. Pay attention to the following aspects:
A、Obey the plan of the civil construction and installation.
B、The opening of the installation project shall be drilled and the wall of the upper and lower water pipes shall be cut and repaired;
C、For the preparatory work of decoration units, protection measures should be taken.
D、It is possible to have a weekly site meeting, coordinate the construction sequence, and the scope of construction area responsibility.

1、Why there is wall paint lacquer defects?
The morbidity of the wall paint and coating can be generated before the paint is applied, it can also occur during or after the construction. Understanding the morbidity of paints and coatings can help to take preventive measures.The main causes of morbidity are the following:
1、The quality of the wall paint itself: Base material used for wall paint and its properties, ratio of base material to pigment and filler (determination of PVVC or P/B), the fineness of the pigment, the filler, the dispersion in the binder, the choice of the auxiliaries, and the appropriate dosage.
2、The condition of the construction at the base level: The base material, the surface roughness, the wall temperature, the pH value, the maintenance period and the proper base material treatment, the quality of the putty used.
3、Coating process: coating thickness, construction program, whether the primer and topcoat are matched, and the interval time between two paintings.
4、Construction operation:Before construction, whether the paint is stirred evenly, whether it is diluted with water, the quality and operation of the construction machine, and the skill of the construction operator.
5、Construction environment: climate conditions during construction, such as temperature, humidity, wind and whether it is rainy or not.

 

2、Why does the wall paint produce sagging? How to overcome it?
Wall painting sometimes can appear sagging and flowing during construction. The reasons are as follows:
1、The paint itself is too low in viscosity or there is too much water in it.
2、The coating is applied too thick, sag or flow is proportional to the thickness of the coating.
3、Humidity of the construction environment is too high or the temperature is too low.
4、The interval time between spraying or painting is too close or the paint is not stirred evenly before construction.

 

3、In order to avoid sagging or flowing, the following preventive measures can be taken.
1、Ensure that the viscosity of the coating is moderate and the viscosity of the construction is achieved.(If airless spray is applied, water can be added less or no adding.
2、The thickness of the coating is controlled, and the thickness of the film is generally controlled by the 20-25um (dry film).
3、The temperature of the construction environment should be kept above 5°C and the humidity should be less than 85%.
4、Before painting, the paint shall be evenly mixed, and the technical level of construction operators shall be continuously improved to ensure the quality of painting.

 

4、 How to improve the covering quality of wall paint?
There is a direct relationship between the covering quality of the wall paint and the pigment. The lack of covering quality means that the use of pigment’s covering quality is not enough. In order to increase the covering quality of the wall paint, we use pigments with strong covering quality, such as Titania and Lithopone. The amount of pigments to be added is appropriate. We give priority to quality and do not pursue low cost with high profit.In addition, be careful when constructing and do not leave out any space.When the difference between the colors of the base and the surface are too large, in order to ensure a good covering quality, a few more times can be painted.

 

5、Why does the wall paint sometimes change color or fade? How to prevent it?
Wall paint is often exposed to the natural environment,such as the wind, sun and rain. The paint film will discolor and fade after a long time. If the overall surface of the building is unified, even if the discoloration is more serious, it is easier to accept than the partial discoloration.
Discoloration of the coating is usually associated with the base material and the pigment. Some organic pigments have poor light resistance and are not resistant to alkali. Under the effects of sunlight, chemicals, and air pollution, the pigments will change in quality.The pulverization of some pigments will also cause the film to fade, such as the anatase titanium dioxide powder, it is more obvious.The yellowing tendency and poor weather resistance of the base material will also cause discoloration and fading. When designing the formulation of the exterior wall paint, we must choose weatherproof base and pigment.Such as pure acrylic emulsion, styrene acrylic emulsion and rutile type titanium dioxide, iron oxide system and phthalocyanine pigment. It is very important to avoid or reduce the discoloration of the film. This is also the reason why different materials and pigments should be used in the interior and exterior wall paint.

 

6、Sometimes the wall paint is blur, or unevenly colored, what is the reason? How to overcome it?
There are many reasons for the uneven color of the wall paint. There are reasons for the paint itself as well as factors such as the construction and the surface of the substrate. This is the most common and most troublesome problem in construction.
1、There is a floating color in itself. The final color of the paint is formulated by a variety of pigments. Each pigment particle floats on top of it. The dense pigment particles aggregate in the lower part, resulting in color separation.After being fully stirred, the coating still tends to produce a difference in color after drying.
2、The pigments in the paint do not disperse well, or two or more pigments do not mix well with one another.The poor dispersion of the pigment or the density difference is too large. When the brush or roller coating is applied, a striped color difference occurs in the direction of the brush and the roller, then, there is floating color.In addition, after the coating film is dried, floating spots are generated due to uneven floating of the pigment particles.
3、Brushing unevenly during construction. Uneven coating thickness and unskilled construction can also result in shades of color.
4、Base surface roughness is different. If the base material is too alkaline, the absorption of the applied paint will be uneven, and the color will be uneven.The color of the coating may be different from the large area when the cover part of the scaffold is reproduced or painted, and the color and lustre will be uneven.

 

7、In order to overcome the wall paint is blur, or unevenly colored, we can take the following preventive measures:
1、Material dispersing agent. It is best to use organic and inorganic dispersants to make the pigments in good stability and dispersion.
2、Improve the viscosity of wall paint. If the viscosity is too low, the phenomenon of floating color is serious; if the viscosity is high, even if the density of the pigment is different, the tendency of stratification will be reduced.
3、Fully stir before construction, so that the paint is uniform, no floating color or precipitation. In construction, do not dilute too much water.
4、Strive for uniformity during construction, in strict accordance with the operating procedures, the coatingfilm should not be too thick, the thicker the coatingfilm, the more prone to floating color.
5、In order to make the base layer to absorb the paint evenly, it is best to apply a coating sealer.
6、Scaffold shielded parts should be carefully handled when repainted or brushed, and the amount of coating should not be less than the specified amount.Use the same batch of paint as far as possible to ensure that the overall decoration color is consistent.
