The rubber is need blooming. And how to explain it? Meishen Technology has a kind of product: special magnesium oxide used for wire&cable. Therefore, Meishen introduces something about the rubber blooming and hopes that you can gain some understanding.
The rubber blooming includes the surface blooming of sizing material and he surface blooming of product. For the forms of rubber blooming, it can be divided into three kinds: powder spraying, oil injection(also called exudation), and wax spray.
The oil injection is a a layer of grease which is separated out by liquid accessory ingredients, such as softener, tackifier, lubricant, plasticizer and so on. During the practice, the rubber surface blooming sometimes appears in a form, and sometimes appears in two or three forms simultaneously.
The powder spraying is a layer of powder which is separated out by powdery accessory ingredients such as vulcanizing agent, accelerant, activator, antiager, stuffing bulking agent and so on.
The wax spray is a layer of wax film which is separated out by wax such as paraffin, ozocerite and others.
Because of the different producing areas, textures, preparations, technology, batches, the raw materials have great discrepancy. It will lead the different solubility because of the different rubber synthetic processes, polymerization temperatures, catalysts and synthon. Therefore, the purity, moisture, ash content, pH value, physical property and other will change.
The above is from the expert of Hebei Meishen Technology Co., Ltd, we hope that it will help you.
