Preliminary Study on Application of Silicone Oil Stabilizer -- 2020-09-29

At present, the silicone oil emulsion used in the textile printing and dyeing industry is very extensive, and the amount of use is also very large. Roughly speaking, the most mainstream silicone oil emulsions are divided into two categories:1. Ordinary amino silicone oil emulsion       This category is currently mainly reflected in ice-feeling silicone oil, smooth silicone oil, smooth silicone oil, soft silicone oil, etc. It is mainly used on cotton and cotton blended stretch ...

Traditional softener and silicone softener -- 2020-09-28

Softeners can be divided into two types: fatty acid derivatives and silicone oils. The former is a traditionally widely used softener, and the latter is a new species that comes from behind. The development of silicone softeners is fast, and new varieties with various properties and functions are constantly being developed and marketed.Because silicone softeners not only have better softening effect than traditional softeners, but also the finishing effect has better durability. Therefore, it ha ...

Introduction and development of Silicone anti-sticking agent -- 2020-09-27

Silicone anti-sticking agent refers to a kind of anti-sticking material with low toxicity, low polarity, low surface tension and immiscibility with organic polymers. It is a kind of anti-sticking agent widely used at present. Silicone anti-sticking agent is currently the most widely used anti-sticking agent, and it is also a kind of organic silicon material with huge market and broad prospects.There are three types of silicone release agents: solvent type, water emulsion type, and solvent-free t ...

Application of silicone oil defoamer in petroleum industry -- 2020-09-25

Silicone oil defoamers are widely used in the petroleum industry and have become an indispensable and important additive in the production process. Due to the extensive use of strong foaming surfactants in drilling fluids, defoamers are not only indispensable for extracting crude oil, but defoamers must also be used in the post process of crude oil refining. In the crude oil distillation process, silicone oil defoamer is used. Secondly, the gas removed from the top of the tower or the natural ga ...

The difference between oily and water-based waterproof materials -- 2020-09-24

One: Environmental protection From the perspective of environmental protection, water-based coatings have natural advantages over oil-based coatings (solvent-based wood coatings). In theory, the lower the VOC content, the higher the environmental protection, but the low VOC content has an impact on the abrasion resistance, hardness, and scratch resistance of oil-based coatings. The above indicators have always been technical problems that need to be overcome in water-based coatings. How to achie ...

The defoaming principle of defoamer -- 2020-09-23

1. The local surface tension of the foam decreases and the foam collapsesThe origin of this mechanism is to sprinkle higher alcohol or vegetable oil on the foam. When it dissolves into the foam liquid, it will significantly reduce the surface tension there. Because these substances are generally less soluble in water, the reduction in surface tension is limited to the local area of ​​the foam, while the surface tension around the foam hardly changes. The part with reduced surface tension is pu ...

Classification of waterproof coatings -- 2020-09-22

There are many types of water materials, which are divided into 4 categories according to their main raw materials: ①Asphalt waterproof materials. Using natural asphalt, petroleum asphalt and coal tar pitch as the main raw materials, the asphalt felt, paper tire asphalt felt, solvent-based and water-emulsion asphalt or asphalt rubber coatings and ointments are made with good cohesiveness, plasticity, Water resistance, corrosion resistance and durability. ②Rubber plastic waterproof materials. U ...

Silicone oil application range and future development -- 2020-09-21

Silicone oil has a very wide range of applications. It is not only used as a special material in aviation, cutting-edge technology, and military technology, but also used in various sectors of the national economy. Its application range has been expanded to: construction, electronics, textiles, automobiles, machinery, leather Papermaking, chemical and light industry, metal and paint, medicine and medical treatment, etc. The main applications of silicone oil and its derivatives are: release agen ...

The Role of Foam Stabilizer -- 2020-09-18

Foam stabilizer is a kind of surfactant, and its functions in the production process of polyurethane rigid foam plastics are as follows:(1) EmulsificationThe surface tension of raw material system is reduced and the miscibility of raw material components is improved.(2) NucleationPromote the formation and stabilization of bubble core in the early foaming stage, regulate the structure, diameter and distribution of bubble hole.(3) Stabilizing effectImprove the stability and fluidity of the expande ...

Characteristics of hydrophilic amino silicone oil -- 2020-09-17

Hydrophilic amino silicone oil is a newly developed new generation of self-emulsifying amino silicone oil. Because its structure has hydrophilic reactive amino groups, it does not require surfactants and is easily dispersed by water. It is a basic combination specially used in textile softener and lubricant formulations. It can be used alone, or together with other silicones or with non-silicon softeners. This compatibility makes it possible to mix special softeners. It can endow the fabric with ...
