The largest amount of tire reclaimed rubber, the most widely used, involving construction, engineering, family, sports facilities, transportation and other fields. The use of rubber tire reclaimed rubber production, the sulfur is an indispensable curing agent, under certain conditions it can linear structure of the rubber molecules in a network structure, with the degree of sulfur compound increases, the network density increases, The more vulcanized bridge raw rubber, the body will be more dense grid, and renewable rubber products hardness, strength and heat resistance will increase. So tire reclaimed rubber production of rubber products, sulfur how much to add it?
In actual operation, the amount of sulfur should be determined as the case may be, which is directly related to the raw material, performance of the tire reclaimed rubber, the type of product produced and the grade, and also has some connection with the engineer's experience. In the reclaimed rubber 2008 standard, 3.5 parts of sulfur are used for every 300 ordinary reclaimed rubber. Such as force tire products, processing grade is not high, about 50 kg of recycled plastic about 350g of sulfur.
Tire recycled rubber products, the amount of sulfur and recycled plastic replaceable to the proportion of the original plastic: For example, 100 parts of raw rubber, reclaimed rubber 300 parts, you can add 3-5 parts of sulfur, which is based on the quality of reclaimed rubber and the type of product decisions, the general Under the circumstances, 300 copies of the tire reclaimed rubber can reach 100 copies of the original plastic, sulfur dosage according to product performance fine-tuning.
The amount of sulfur used in tire reclaimed rubber products is also related to the habits of engineers: Some engineers use 100 parts of reclaimed rubber with 1.5-1.8 parts of sulfur, some 100 parts of RR use 2 parts of sulfur, and another 100 parts of engineering raw rubber and 180 parts of recycled The glue uses 3.5 parts of sulfur, which is based on different data obtained by many engineers over many years of experience, and is directly related to their habits and types of products.
The use of latex reclaimed rubber, EPDM reclaimed rubber, butyl reclaimed rubber, nitrile reclaimed rubber production of rubber products, but also can be based on the above experience to add appropriate amount of sulfur; reclaimed rubber products sulfur consumption, not a word, an example, An article can be answered, more sulfur will blooming, smoke; less sulfur can not reach the effective crosslinking density, reduce the intensity of recycled rubber products. In short, the amount of reclaimed rubber in the formula to meet both national standards, but also according to the quality of reclaimed rubber products, in fact, may be.
