保温胶粉是一种在工程建设中很重要的材料，主要有骨料和辅料组成，骨料主要就是水泥，砂，辅料有羟丙基甲基纤维素，可再分散性乳胶粉，抗裂纤维等，由于原料多，配比严格，所以在生产过程中难免会出现一些问题，下面济南保温胶粉厂家就总结下常出现的问题。

Thermal insulation adhesive powder is a very important material in engineering construction, mainly composed of aggregates and auxiliary materials. The aggregates are mainly cement, sand, and auxiliary materials include hydroxypropyl methyl cellulose, redispersible latex powder, crack resistant fibers, etc. Due to the large number of raw materials and strict ratio, some problems may inevitably occur during the production process. Below, Jinan thermal insulation adhesive powder manufacturer will summarize the common problems.

使用的砂的大粒径一般小于3.5mm，远远小于标准规定的4.75mm，施工时工人感觉保温胶粉还是较粗，其实感觉较粗主要是砂浆的和易性差，施工性不好，显得大颗粒较多，主要原因在于人工砂的颗粒级配不好，往往砂的组成是两头多，中间少，需要补充中间区域的砂。

The large particle size of the sand used is generally less than 3.5mm, which is much smaller than the standard requirement of 4.75mm. During construction, workers feel that the insulation adhesive powder is still relatively coarse. In fact, the main reason for the coarser feeling is that the workability of the mortar is poor, and the workability is not good, resulting in a large number of large particles. The main reason is that the particle size of artificial sand is not good, and the composition of the sand is often more at both ends and less in the middle, so it is necessary to supplement the sand in the middle area.

抹灰、空鼓开裂分为塑性开裂和干缩开裂两种。塑性开裂是指保温胶粉在硬化前或硬化过程中产生开裂，它一般发生在砂浆硬化初期，裂纹一般都比较粗，裂缝长度短;干缩开裂是指砂浆在硬化后产生开裂，它一般发生在砂浆硬化后期，裂纹特点是细而长。

Plastering and hollow cracking are divided into two types: plastic cracking and dry shrinkage cracking. Plastic cracking refers to the cracking of insulation adhesive powder before or during the hardening process. It generally occurs in the early stage of mortar hardening, and the cracks are generally relatively thick and short in length; Dry shrinkage cracking refers to the cracking of mortar after hardening, which generally occurs in the later stage of mortar hardening and is characterized by thin and long cracks.

塑性开裂主要是由于保温胶粉抹灰后不久，在塑性状态下由于水分散失快而产生收缩应力，当收缩应力大于砂浆自身的粘结强度时，表面产生裂缝。它往往与砂浆的性能和温度、环境温度以及风度等有关系。水泥用量大，砂细度模数越小，含泥量越高，用水量越大，砂浆保水性差，砂浆越容易发生塑性开裂。

Plastic cracking is mainly due to the shrinkage stress caused by the rapid loss of water in the plastic state shortly after the insulation adhesive powder is plastered. When the shrinkage stress is greater than the bonding strength of the mortar itself, surface cracks occur. It is often related to the performance and temperature of mortar, environmental temperature, and wind strength. The larger the amount of cement used, the smaller the fineness modulus of sand, the higher the mud content, and the higher the water consumption. The water retention of mortar is poor, and the mortar is more prone to plastic cracking.

干缩开裂主要由于保温胶粉水泥用量大、强度高导致体积收缩;施工后期养护不到位;砂浆掺合料或添加剂干燥收缩值大;墙体本身开裂;界面处理不当;砂浆强度等级乱用或用错;基材与砂浆弹性模量相差太大等。

Dry shrinkage cracking is mainly caused by the large amount and high strength of insulation rubber powder cement, which leads to volume shrinkage; Insufficient maintenance in the later stage of construction; The drying shrinkage value of mortar admixtures or additives is high; Cracking of the wall itself; Improper interface handling; Misuse or misuse of mortar strength grade; The difference in elastic modulus between the substrate and mortar is too large.
