In wall construction, putty powder is an indispensable process, but also an important link. The construction technology and quality of putty powder are related to the beauty of the wall and the service life. So what is putty powder? Let's take a look at it.

Putty is generally composed of base material, filler, water and additives, also known as binder, is the most critical component of putty, mainly plays various roles such as bonding. Putty most commonly used binder is cement and organic polymer, organic polymer also has emulsion and latex powder. Cement is a good bonding agent with good durability and reasonable cost performance, but its tensile strength and crack resistance are poor. The organic polymer can modify and toughen the putty, so as to improve its properties.
填料主要起填充作用,常用的有碳酸鈣、滑石粉和石英砂等。應(yīng)注意填料細(xì)度的搭配使用。助劑有增稠劑、保水劑等。增稠劑和保水劑起保水、改善貯存和施工性能的作用,一般使用纖維素類。抗凍劑主要是改善膩?zhàn)釉诘蜏叵碌馁A存穩(wěn)定性,滑爽劑和減水劑等一般用在膩?zhàn)又?,改善膩?zhàn)拥氖┕ば阅?
The fillers are mainly filled with calcium carbonate, talc powder and quartz sand. Attention should be paid to the combination of filler fineness. Auxiliaries include thickeners and water retaining agents. Thickener and water retaining agent play the role of water retaining, improving storage and construction performance, generally using cellulose. Antifreeze agent is mainly used to improve the storage stability of putty at low temperature. Smoothing agent and water reducing agent are commonly used in high-grade putty to improve the construction performance of putty.

Putties are classified in different ways. Putties can be divided into two types: inner wall and outer wall. Exterior wall putty should resist wind and sunshine, so it has high glue property, high strength and slightly lower environmental protection index. The comprehensive index of putty in inner wall is better, healthy and environmental protection.

Putty is also divided into oily putty and water-based putty, respectively, for paint, latex paint construction, we usually refer to putty is "water-based putty".

Putties can be divided into non-finished putty and finished putty.

1) Non-finished putty refers to putty products without fixed packaging, unified production standards and any means of production and quality assurance system. This kind of product generally uses the user's room as the manual workshop, the construction worker concurrently produces the worker, each kind of ingredient quantity, whether or not depends on the construction worker to grasp at will.
2)成品膩?zhàn)邮歉鶕?jù)合理地材料配比、機(jī)械化方式生產(chǎn)出來的,避免了傳統(tǒng)工藝中現(xiàn)場配比造成的差錯以及質(zhì)量得不到保證的問題。相對環(huán)保一些,無毒無味,甲醛、苯、二甲苯以及揮發(fā)性有害物質(zhì)控制在標(biāo)準(zhǔn)范圍內(nèi),兌水即用,操作方便,工藝簡單。
2) The finished putty is manufactured according to reasonable material ratio and mechanized method, which avoids the errors caused by on-site mixing in traditional technology and the problem that the quality can not be guaranteed. 相對環(huán)保一些,無毒無味,甲醛、苯、二甲苯以及揮發(fā)性有害物質(zhì)控制在標(biāo)準(zhǔn)范圍內(nèi),兌水即用,操作方便,工藝簡單。
