Honeycomb board turnover box is a kind of plastic honeycomb board which is made of copolymerized polypropylene as the main material.And other polypropylene plastic honeycomb board is the same, honeycomb board turnover box is a beautiful color, high strength, light quality, long service life, insect-proof, moisture-proof, mildew-proof, non-toxic, clean sanitation, health, simple cleaning and convenient transfer of larger containers.The structure of the revolving box can be divided into two types: fixed and folding. The stationary revolving box is formed by a single injection in a larger injection machine (injection can be more than 1000cm3).Folding turnover box is assembled by a number of parts, each part in different standards of injection machine parting injection molding, and then assembled together.
The turnover box is mainly used for the turnover and transportation of all kinds of food, beverage, agricultural products, industrial parts, chemical products and pharmaceuticals, etc., so as to facilitate the packing, storage, transfer and storage of all kinds of goods.
Honeycomb board,PP honeycomb board materials directly affect the quality of honeycomb board, so we have the following requirements for honeycomb board,PP honeycomb board materials:
The material itself hygroscopicity is bad, generally does not need to be dry, but when the material moisture content exceeds 0.1%, must be dry.That's between 70 and 80.C in the hot air cycle boring 2 ~ 3h.Honeycomb plate for amorphous plastic, viscosity, fluidity, thermal stability are good, injection is relatively simple.The honeycomb plate used for injection has a relative molecular mass of about 7 if 200,000, and the molding temperature is relatively wide. A small amount of shaking of the temperature in the viscous flow state will not affect the process of injection.
(2) the coloring method of the material, with the floating dye or to take part in the color masterbatch, according to the share of the particle guess, mix evenly.Such as plunger injection machine, in order to prevent color difference, should be mixed evenly after the match color material extrusion granulation injection production.
