Five methods of color production of Automotive Wiring Harness Protection Sleeve

Automotive Wiring Harness Protection Sleeve are widely used in actual production due to their high strength and high elasticity. Automotive Wiring Harness Protection Sleeve are transparent and colorless, while Automotive Wiring Harness Protection Sleeve in real life are colorful. So how are Automotive Wiring Harness Protection Sleeve made? The following editor will explain five production methods for you.

1. Solution coloring
This method is to dissolve the knitted sleeves into a solution of a certain concentration with its good solvent, then add the coloring agent and the knitted sleeve compounding agents except sulfur into the solution, stir and mix evenly, dry at a certain temperature to remove the solution, and finally Add sulfur to the rubber mixer.
2. Dry powder coloring
This method is to directly add the powdery toner together with the small materials in the knitting sleeve, and knead on the mill. This method has the advantages of simple operation and low cost, but the dust is large during mixing, polluting the environment and causing color difference.
3. Color paste coloring
This method is to first mix the coloring agent with the liquid compound, grind it with a three-roller machine to form a paste or slurry, and then add it to the knitted sleeves in a certain proportion for mixing. This method can prevent dust from flying, and is also conducive to the dispersion of toner in the Braided Sleeve and uniform color.
4. Coloring of pellets
There are two main ways to prepare toner pellets. The first method is the same as the granulation method of other powdery ingredients. First, the powdery toner surfactant is moistened, and then the wax is melted or melted with the resin and extruded for granulation; the second method is to use the toner with After the surfactant is moistened, the toner particles are refined by the action of mechanical force to form a dispersion of a certain concentration, which is then mixed with the latex and co-precipitated, dried and then rolled into granules.
5. Masterbatch coloring
This method is to first mix the coloring agent, some plasticizers and other ingredients of the knitted sleeves with the raw rubber through an open mill to make a coloring agent masterbatch with a concentration of about 50%, and then add it according to the proportion. Colored in Braided Sleeve.
