Different molecular weight structures of polyethylene glycol and its application fields With the continuous expansion of the application field of polyethylene glycol, the production of polyethylene glycol in countries and regions such as Europe, America and Japan has increased rapidly. There are various types of polyethylene glycol products in foreign countries. The structure of poly(ethylene glycol) is HOCH2[CH2OCH2] nCH2OH or H[ OCH2CH2] nOH is a general term for ethylene glycol polymers having an average molecular weight of 200 to 8000 or more. With the difference in average molecular weight, the properties also vary.
Characteristics and application of cement retention agent Cement tamping agent is a kind of high fluidity, easy to pour and dense material, especially suitable for the production of special-shaped component products. The role of cement sag agent: cement sag agent can keep the concrete slump A fast-loss additive. It can delay the hydration and condensation of cement and achieve the effect of maintaining slump.
