The working quality of the glue beater is affected by the colloid. Choosing the colloid with good quality can greatly improve the stability of the glue beater products. The following two-component glue beater in Jinan popularizes the correct selection principle of the colloid of the glue beater for everyone.
1. Selection of colloids with guaranteed quality
The quality and price of colloids on the market vary from good to bad, some of them are very cheap, and the price is only half of the well-known products of the same kind, or even lower. The physical properties and aging resistance of these low-cost and low-quality colloids can not meet the durable service life of doors and windows. At the same time, the quality accidents caused by low-price and inferior colloids may cause customers to pay several times or even dozens of times the cost of purchasing rubber, which will cause serious social impact and damage the reputation of enterprises. Here, we suggest that users must choose colloids with guaranteed quality.
How to choose colloids with guaranteed quality? The quality of colloids is related to the quality of raw materials, formula composition, consumption technology, quality control system and other factors. In this regard, users are encouraged to understand and pay attention to the R&D ability, testing level, consuming technology, consuming equipment and quality control system of consumer manufacturers.
2. Reject "Oil-filled glue" resolutely
At present, domestic colloids are mainly silicone sealants, and a large part of the low-cost and inferior silicone sealants on the market are commonly called "oil-filling glue" by using various alkane plasticizers (white oil, liquid paraffin, collectively called mineral oil) instead of expensive silicone-based polymers to reduce costs. They usually absorb customers at a low price, the price is very cheap, and the problem can not be seen at the beginning of application. But after a few months to six months, the problems of these products will gradually emerge, presenting cracking, pulverization, hardening, oil flowing and other problems, which will bring great disturbance and serious losses to customers!
How can we quickly identify whether the colloid is "oily"? Here we share a quick and simple identification method. When the colloid is hit on the plastic film, the sealant filled with mineral oil will shrink the plastic film paper after the colloid solidifies for a period of time. For example, the larger the amount of mineral oil filled with sealant, the shorter the shrinkage time of the plastic film will be, and the more obvious the shrinkage phenomenon will be.
