The epoxy resin is diluted with a reactive diluent and a non-reactive diluent. The reactive diluent is mainly a glycidyl ether-based substance, and the non-reactive diluent is, for example, an inert solvent such as toluene, ethanol, acetone, butanol, or the like. Butyl ester and the like. Reactive diluents have the disadvantages of high price, high volatility, and high toxicity (reactive diluents with low volatility are expensive). Inactive diluents are inexpensive, but generally belong to the VOC range, and have now begun to be restricted. Dibutyl esters and the like are not volatile, but migration and other disadvantages may occur. According to my previous experience, benzyl alcohol can be used as a plasticizer for epoxy resins, and the effect is many, with the following points: 1. The material itself is non-toxic (can be used for human injection reagents) 2. High boiling point, not volatile, and after curing, due to the strong polarity of benzyl alcohol, it can be well compatible with epoxy resin, and there is no migration phenomenon. 3. Benzyl alcohol can promote the reaction of epoxy resin with amine, speed up the reaction 4. Benzyl alcohol has good hydrophobic properties, which can significantly improve the gloss of the coating and reduce the appearance of white birch. 5. Benzyl alcohol can improve the toughness of the cured product. Pay attention to the following points during use: 1. Benzyl alcohol needs to be stored in the dark, otherwise it will turn yellow. 2. Can only be used in epoxy/amine curing systems, especially in epoxy/anhydride systems. 3. The amount of addition should be controlled, because the addition of benzyl alcohol will reduce the mechanical properties and solvent resistance and chemical resistance of the cured product, so it is necessary to determine the proportion of addition according to actual requirements. 4. Benzyl alcohol can significantly increase the curing speed, so this needs to be considered. Benzyl alcohol has rarely been reported in the literature and in the literature, but in practice, many manufacturers use benzyl alcohol as a diluent, especially for diluting the curing agent.
The working principle of a High Flow Peristaltic Pump like a snake swallowing an egg. The hose is constantly squeezed through the roller to make the hose generate pressure and push the liquid forward. Our designers make the Peristaltic pump head and hose fit perfectly by designing precise roller size and pump head structure. So as to achieve the purpose of accurate liquid metering transmission or filling
1. Clean and pollution-free: the fluid only passes through and touches the peristaltic pump hose. High Flow Peristaltic Pump,Additive Peristaltic Pump,Polishing Liquid Pumps,Intelligent Transfer Peristaltic Pump Baoding Chuangrui Precision Pump Co., Ltd. , https://www.crprecisionpumps.com
2. High precision: constant current, reproducibility of up to 0.5%, and flow can be precisely adjusted.
3. Low shear force: It is an ideal tool for conveying shear-sensitive and corrosive fluids.
4. Corrosion resistance: it can transport various fluids, such as organic solvents and corrosive liquids.
5. Idling and dry operation: air or gas-liquid-solid three-phase mixed transportation can also be transported.
6. Possess self-priming ability: self-priming, no need to fill the pump, no need to empty.
7. With stop valve function, no siphon, no seals, stop valve and check valve function.
8. Two-way conveying function: reverse pumping and back-suction functions can be realized by changing the direction of the pump runner.
9. Simple maintenance: only need to replace the peristaltic pump hose, no valve and seal replacement.
