宝博体育腻子粉脱粉?原来是这些原因导致的!

来源:http://annesgiftsonline.com宝博体育 日期:2021-05-19 发布人:juyehe

腻子粉是建筑装饰材料的一种,主要成分是滑石粉和胶水。刚刚购置的毛坯房表面的一层白色是腻子,通常腻子的白度在90以上细度在330以上。

Putty powder is a kind of building decoration materials, the main components are talcum powder and glue. Just bought a layer of white on the surface of the blank room is putty, usually the whiteness of putty is more than 90, fineness is more than 330.
腻子是用来墙面修补的一种基材,为下一步装饰(刷油漆贴壁纸)打下良好的基础。
Putty is a kind of base material used for wall repair, which lays a good foundation for the next decoration (painting and wallpaper).
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,所以内墙不外用,外墙不内用。
Putty can be divided into interior wall and exterior wall. Exterior wall putty is resistant to wind and sun, so it has high gel, high strength and low environmental protection index. The composite index of interior wall putty is good, healthy and environmental protection, so the interior wall is not for external use, and the exterior wall is not for internal use.

通常腻子是石膏或者水泥基的,这样表面粗糙比较容易粘接牢固。但是在施工的时候还是要在基层上涂刷一层界面剂来封固基层同时提高墙面的附着力,让腻子能够更好的粘结在基面上。
Usually putty is gypsum or cement-based, so the surface is rough and easy to bond firmly. But in the construction, we should brush a layer of interface agent on the base to seal the base, and improve the adhesion of the wall, so that the putty can be better bonded on the base.
许多腻子粉使用者不得不承认,腻子胶粉脱粉是一个很严重的问题,它会引起乳胶漆的脱落,以及腻子层的起鼓,裂缝,进而引起乳胶漆饰面发生裂缝。
Many users of putty powder have to admit that it is a very serious problem for putty powder to come off. It will cause the peeling off of emulsion paint, the bulging and cracking of putty layer, and then the cracking of emulsion paint finish.
腻子粉脱粉掉粉、掉白是目前常见的腻子施工后问题,要了解腻子粉脱粉的原因,首先要了解腻子粉的基本原材料组分与固化原理,然后结合腻子施工时的墙面干燥程度、吸水率,温度、天气干燥程度等。
Putty powder off powder, off white is the common putty construction problems, to understand the reasons for putty powder off powder, first to understand the basic raw material components of putty powder and curing principle, and then combined with the putty construction of the wall dry degree, water absorption, temperature, weather dry degree.
今天福华建材小编找出了腻子粉掉粉的主要原因,一起来看看吧!
Today, Fuhua building materials Xiaobian found out the main reason of putty powder off powder, let's have a look!
原因一
Reason one
腻子的粘结强度不够造成脱粉,生产厂家一味的降低成本,胶粉的粘结强度差,添加量较小,特别是内墙腻子,粘结强度的大小,脱粉不脱粉和胶粉以及胶水的质量和添加量有很大关系。
The adhesive strength of putty is not enough, which leads to powder removal. The manufacturer blindly reduces the cost. The adhesive strength of rubber powder is poor, and the amount of addition is small. Especially for the interior wall putty, the adhesive strength, powder removal without powder removal are closely related to the quality and amount of rubber powder and glue.
原因二
The second reason
设计配方不合理,选材的问题和结构的问题,在腻子配方中很重要。比如羟丙基甲基纤维素(HPMC)做内墙不防水的腻子,HPMC虽然很贵,但对双飞粉,滑石粉,硅灰石粉等填充料不起作用,如果仅使用HPMC就会引起脱粉,而价格低的CMC、CMS反到不脱粉,但是CMC、CMS不能做防水腻子,也不能做外墙腻子,因为CMC和CMS遇到灰钙粉、白水泥起反应,这都会引起脱粉,也有把聚丙烯酰胺加入灰钙粉、白水泥做为防水涂料,也会起化学反应引起脱粉。
Unreasonable design formula, material selection and structure are very important in putty formula. For example, hydroxypropyl methylcellulose (HPMC) is used as non waterproof putty for interior wall. Although HPMC is very expensive, it does not work for filling materials such as Shuangfei powder, talcum powder and wollastonite powder. If only HPMC is used, it will cause powder removal. However, CMC and CMS with low price can not be used as waterproof putty or exterior wall putty, because CMC and CMS meet with lime powder, talcum powder and silica fume powder White cement reacts, which will cause depigmentation. In addition, adding polyacrylamide into lime calcium powder and white cement as waterproof coating will also cause chemical reaction to cause depigmentation.
原因三
The third reason
混合搅拌不均匀,是造成内外墙腻子脱粉的主要原因,全国有的生产厂家生产腻子粉设备简单,五花八门,不是专用搅拌设备,搅拌不均匀,引起腻子脱粉。
Uneven mixing and mixing is the main reason for the internal and external wall putty powder removal. Some manufacturers in China produce putty powder with simple and varied equipment, which is not a special mixing equipment. Uneven mixing causes putty powder removal.
