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.

　　膩子一般是由基料、填料、水和助劑等組成基料，也稱粘結(jié)劑，是膩子的關(guān)鍵組分，主要起粘結(jié)等各種作用。膩子常用的粘結(jié)劑是水泥和有機聚合物，有機聚合物又有乳液和乳膠粉之分。水泥是粘結(jié)性好、耐久和性價比合理的粘結(jié)劑，但拉伸強度和抗裂性較差。有機聚合物可對其改性和增韌，從而提高膩子性能。

　　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?？箖鰟┲饕歉纳颇佔釉诘蜏叵碌馁A存穩(wěn)定性，滑爽劑和減水劑等一般用在膩子中，改善膩子的施工性能.

　　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.

　　膩子的分類有不同的方法，膩子分為內(nèi)墻和外墻兩種。外墻膩子要抵抗風吹日曬所以膠性大、強度高，環(huán)保指數(shù)稍低。內(nèi)墻膩子綜合指數(shù)較好，健康環(huán)保。

　　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.

　　膩子又分油性膩子與水性膩子兩種，分別用于油漆、乳膠漆施工，我們平常說的膩子都是指“水性膩子”。

　　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".

　　膩子分為非成品膩子和成品膩子兩類

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

　　1）非成品膩子，指的是沒有固定包裝、沒有統(tǒng)一生產(chǎn)標準、沒有任何生產(chǎn)手段與質(zhì)量保證體系的膩子產(chǎn)品。這類產(chǎn)品一般以用戶居室作為手工作坊，施工工人兼生產(chǎn)工人，各種配料的多少、有無全憑施工工人隨意掌握。

　　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）成品膩子是根據(jù)合理地材料配比、機械化方式生產(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)控制在標準范圍內(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)控制在標準范圍內(nèi)，兌水即用，操作方便，工藝簡單。
