3. Batching process:
① Raw materials into the workshop should have the name, batch, date, weight, check whether there is a certificate, a certificate. Technically allowed to use raw materials must have a technical notice, otherwise can not be used.
② All kinds of weighing tools are required to be accurate, must be regularly checked by technical personnel, without proofreading or proofreading is not allowed to use.

④ Check the appearance of raw materials before dosing, and there is no debris and deterioration.
⑤Weighing tolerance of the compound: Manual: sulfur, adhesive, plasticizer tolerance±10g; Weighing tolerance of accelerator and anti-coke agent ±5g; Resin, oxidized asphalt tolerance ±20g; Automatic small scale: screw proportioning scale tolerance ±10g; Vibration proportioning scale tolerance ±20g;
⑥It is necessary to understand the various compounding agents in the rubber formula, strictly according to the rubber production formula and operation instructions, carefully dosing, the variety should be consistent, and be meticulous, accurate, good, and not leaking. Special hand-made ingredients the first car has to be configured by two people.
⑦ The prepared drugs should be checked item by item, proofread and correct (weight tolerance meets the process requirements), hang the small card on the obvious bag in the front row, write the name and weight of the material, and classified storage, easy to use, not mixed.
⑧ When preparing the final rubber compounding agent, each polyethylene bag is only allowed to hold one kind of compounding agent, and a polyethylene bag with a low melting point (80℃) must be used, and the polyethylene bag with the final rubber is strictly prohibited.
⑨ Use the rest of the small materials, to be sealed and stored to prevent moisture. Raw materials should be as far as possible to avoid sunlight, to avoid exposure to the air, such as the adhesive cobalt caprate, exposed to the air is easy to oxidize, generally quantitative packaging, from the batching room to the mixer is not more than 1 hour.
