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.

　　腻子一般是由基料、填料、水和助剂等组成基料，也称粘结剂，是腻子的关键组分，主要起粘结等各种作用。腻子常用的粘结剂是水泥和有机聚合物，有机聚合物又有乳液和乳胶粉之分。水泥是粘结性好、耐久和性价比合理的粘结剂，但拉伸强度和抗裂性较差。有机聚合物可对其改性和增韧，从而提高腻子性能。

　　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，常用的有碳酸钙、滑石粉和石英砂等。应注意填料细度的搭配使用。助剂有增稠剂、保水剂等。增稠剂和保水剂起保水、改善贮存和施工性能的作用，一般使用纤维素类。抗冻剂主要是改善腻子在低温下的贮存稳定性，滑爽剂和减水剂等一般用在腻子中，改善腻子的施工性能.

　　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.

　　腻子的分类有不同的方法，腻子分为内墙和外墙两种。外墙腻子要抵抗风吹日晒所以胶性大、强度高，环保指数稍低。内墙腻子综合指数较好，健康环保。

　　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.

　　腻子又分油性腻子与水性腻子两种，分别用于油漆、乳胶漆施工，我们平常说的腻子都是指“水性腻子”。

　　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".

　　腻子分为非成品腻子和成品腻子两类

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

　　1）非成品腻子，指的是没有固定包装、没有统一生产标准、没有任何生产手段与质量保证体系的腻子产品。这类产品一般以用户居室作为手工作坊，施工工人兼生产工人，各种配料的多少、有无全凭施工工人随意掌握。

　　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）成品腻子是根据合理地材料配比、机械化方式生产出来的，避免了传统工艺中现场配比造成的差错以及质量得不到保证的问题。相对环保一些，无毒无味，甲醛、苯、二甲苯以及挥发性有害物质控制在标准范围内，兑水即用，操作方便，工艺简单。

　　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. 相对环保一些，无毒无味，甲醛、苯、二甲苯以及挥发性有害物质控制在标准范围内，兑水即用，操作方便，工艺简单。
