You have to know the four kinds of non-woven production process

In terms of product development, China's masterbatch manufacturers have developed a non-woven masterbatch, black masterbatch, fiber masterbatch, film masterbatch, cable masterbatch, polyolefin masterbatch , PVC masterbatches, plastic products with masterbatch. Non-woven masterbatch production process is generally divided into: flushing method, ink method, kneading method, a metal soap method four, the following four kinds of non-woven masterbatch production process follows specific description:

1, the flushing method: pigment, water and dispersant through sanding, the pigment particles are smaller than 1μm, and by phase transfer method, the pigment into the oil phase, and then dried to obtain masterbatch. Need to use organic solvents, and when appropriate solvent recovery phase inversion.
Its process: washing fine paste and dried and evaporated concentrate added to the support extrusion granulation

2, the ink method: As the name suggests, is the use of the ink paste production methods in masterbatch production, namely by three-roll mill, the pigment surface coated with a layer of low molecular weight protective layer. Fine paste after grinding again and the carrier resin is mixed, then by two-roll mill (also called two-roll mill) plasticized, and finally through a single-screw or twin-screw extruder granulation.
The process is as follows: Ingredients stirring fine coarse paste three-roll grinding paste two roll mill extrusion granulation

3, the metal soap method: After grinding the pigment particle size of around 1μm, and add soap at a certain temperature, so that each pigment particle surface layer evenly wetted soap, forming a layer of liquid saponification, when the metal salt Saponification layer pigment surface chemical reaction to produce a layer of metal soap and a protective layer (magnesium stearate) was added after, so that the pigment particles were milled after not cause flocculation, protect certain fineness

4, kneading method: after mixing the pigment and oil carrier, the use of pigment lipophilic this feature, by kneading the pigment from the aqueous phase into the oil phase rinse. While the oil-based carrier coated pigment, the pigment dispersion stability, prevent pigment agglomeration.

More than four kinds of non-woven masterbatch production technology, is more common in non-woven masterbatch production, you know, oh!
