Putty is divided into two categories: unfinished putty and finished putty;
1. Incomplete putty refers to putty products without fixed packaging, unified production standards and any means of production and quality assurance system. This kind of products generally take the user's room as a manual workshop, and the construction personnel are also production workers. The quantity and existence of various components are completely determined by the construction workers. In this case, putty is ready.
Another kind of product, mixed powder (such as putty powder) has certain standards, but it still needs to be prepared on site, and the final product also belongs to non-standard putty (white latex, 108 glue and other chemical fillers are prepared, and the addition amount is not standard, depending on the experience of construction personnel). This kind of putty is completely unknown, whether it is the quality of products or the protection of human health.
2. The finished putty is produced in a reasonable material ratio and in a mechanized way, which avoids the error caused by on-site ratio and the problem that the traditional process cannot guarantee the quality.
It is environment-friendly, non-toxic, tasteless, free of formaldehyde, benzene, xylene and volatile harmful substances, and can be used after being mixed with water, with convenient operation and simple process. Natural plant glue is used as adhesive, which has high bonding strength, good crack resistance and no odor after wall coating.
For some building materials with large formaldehyde emission, we should pay attention to choosing healthier and more environmentally friendly ones.
Building materials that release a lot of formaldehyde, such as paint, semi-finished putty, building glue, wood floor, man-made board, etc., have healthier choices, such as water-based environmental protection paint for paint, finished environmental protection putty for semi-finished putty, environmental protection wall for building glue, solid wood board or tile for wood floor, solid wood board for board and edge sealing.
The principle of expanding data selection putty;
1, waterproof performance
Gypsum powder and chemical glue are needed in the composition materials of wall putty, which are the important foundation of waterproof. Because it is the base of the wall latex paint, it must be waterproof and isolate the direct contact between the wall and the latex paint to prevent the wall from falling off due to moisture.
2, solid performance
The putty must be strong, and the strong putty can be well attached to the wall base and bear latex paint. At the same time, it can also ensure the tough appearance and performance of the wall. Look at its ingredients. It also needs gypsum powder, chemical glue and dried old powder.
3. Leveling performance
An important function of putty is to level the wall, fill the concave part, cover the convex part, and then polish it manually. Putty needs to meet the benign sticky performance.
