The type and introduction of putty.

China Paint Network
News: decoration involves a lot of materials, putty is one of them, mainly used to level the wall, but also the wall
passing
before painting indispensable. But putty kinds are also more, we usually listen to more water putty, anti-crack putty, anti-mold putty and so on, that putty kind in the end how many, how to distinguish? Master Zhong is a thick and honest decoration brusher, but the putty material is very familiar, we also understand:
putty (filling mud) is a decorative material to level the surface of the wall, is a thick slurry paint, is an essential product before painting paint. Apply to primer or directly to objects to remove uneven defects on the surface of the coated material. The use of a small amount of paint base, additives, a large number of fillers and the appropriate amount of coloring pigment preparation, the pigment used is mainly iron red, carbon black, chromium yellow and so on. Fillers are mainly calcium carbonate,
talcum powder
etc. Partially dented work surfaces can be filled or scraped on all surfaces, usually after the primer layer has dried out, applied to the primer surface. Good adhesion is required and no cracks are produced during baking.
1, at present, the market lock sales of putty varieties have water-resistant putty and general type putty is also known as batch wall putty. According to the shape can be divided into powder, paste, two-part three:
powder: it is a gel material and fillers and additives composed of white powder products.
cream: a white paste product made up of synthetic resin emulsions and additions.
two-part product: a product consisting of glue and white powder.
2, commonly used putty according to different engineering projects, different uses can be divided into three categories:
glue old powder putty: from old powder, chemical glue, gypsum powder, bone glue preparation, used to do
water-based paint
flat top inside
oil surface putty: made of oil-based paint, gypsum powder, etc.
oil surface putty: made from oil-based varnish, dry old powder, chemical glue, gypsum powder, used for the original
paint
flat-top wall.
3, putty powder according to the use can be divided into: the outer wall putty powder and the inner wall putty powder.
4, putty powder according to the function can be divided into: waterproof putty, flexible putty, anti-crack putty and so on.
5, by chemical composition:
single-component putty: polymers and fillers (high PVC
interior wall coating
)
-component putty: polymers (single components/double components) and cement and fillers
powder putty: cement , fillers , dispersable polymer
cement putty: the main material of silicate cement putty is cement putty, characterized by high strength, hardness, but the fatal disadvantage is that it is rigid, relatively brittle, easy to crack. Mainly used on exterior walls (which can also be used for interior walls). It is characterized by its high surface strength.
anti-cracking putty: not so strong, but can resist cracking walls, to prevent cracks.
water-resistant putty: water-resistant putty is a kind of building putty, especially to reach the "building indoor putty" (JG/T3049-1998) standard in the N-type, that is, water-resistant putty standard of a class of putty. "Indoor putty" (JG/T3049-1998) is currently the indoor building putty products must meet a minimum standard, all putty that does not meet the requirements of this standard is non-conforming products, prohibited from sale and use.
Big white putty: is what we often say big white powder, also known as talc powder, putty powder, is the home decoration of the wall to find flat common materials, generally in the big white powder to add cellulose, white latex and water, kneaded into a thick shape, to cover the wall, roof, in order to prevent it from cracking, falling off, can be coated with a layer of interface agent on the ground floor.
flexible putty: flexible putty is made of high-quality cement, fillers, synthetic polymers and selected additives, according to the flexibility and waterproof performance of putty, divided into ordinary external wall putty, flexible anti-crack putty, flexible external wall putty and waterproof outer wall putty. When used, add 30% water and stir well. Can be in the sun in the weather under normal construction, with high bonding strength, smooth surface, moisture resistance and other advantages. Suitable for cement mortar, concrete, gypsum board and Et plate and other substrates, as well as the exterior walls of various types of buildings.
elastic putty: "elastic" means that there is a certain amount of pull. Elastic putty is mainly used to find gaps in the wall, because it has a certain pull force, in the wall gap in the temperature / humidity / external force, etc. , and then change, the wall will not appear gaps. But beyond a certain limit there will be gaps, it is white cement , talcum powder , cellulose , 2488 , elastic acrylic emulsion, generally used to require a certain musical effect or soundproofing of the interior wall of the room.
