Rubber bladders can be divided into latex bladders, natural rubber bladders and synthetic rubber bladders according to the raw materials used. Latex reclaimed rubber can be used in rubber bladders that use natural rubber as the main raw material. So in the actual production and application process, what is the role of latex reclaimed rubber in natural rubber bladder? Will the addition of latex reclaimed rubber in the rubber bladder affect the quality of the rubber bladder? What issues should be paid attention to when using latex reclaimed rubber to reduce the production cost of natural rubber bladder?
1. The role of latex reclaimed rubber in natural rubber bladder
The main function of latex reclaimed rubber is to replace part of natural rubber to reduce the raw material cost of various natural rubber products. The first and largest role of using latex reclaimed rubber in natural rubber bladders is to reduce costs. In addition, latex reclaimed rubber has good fluidity and plasticity, and it can improve the performance of rubber compounding process and reduce production energy consumption when used in combination with natural rubber; latex reclaimed rubber has good vulcanization flatness and small vulcanization reaction, which can improve the performance of pure natural rubber vulcanization process ; If the expansion and contraction of the finished rubber bladder is large, blending an appropriate amount of latex reclaimed rubber can improve the shape and dimensional stability of the natural rubber bladder bladder.
2. How to choose the right latex recycling for natural rubber bladder
As an inflatable rubber product, rubber bladders have high requirements on gas permeability resistance. Compared with butyl rubber, natural rubber has certain defects in its gas permeability resistance. Therefore, when using latex reclaimed rubber in natural rubber bladder 2LLYY611, be sure to choose high-fineness latex reclaimed rubber, preferably at 80 mesh or higher, without any impurities, to avoid the occurrence of gas in the rubber bladder due to the presence of impurities The problem of reduced density.
Comprehensively consider the index requirements of rubber bladders, and choose the products that are closest to the various indicators of rubber bladders. In the relevant national standards, the first-class products of natural rubber bladders require a tensile strength of 14 MPa, qualified products with a tensile strength of more than 12 MPa, and rubber bladders with an elongation at break of at least 550%. Rubber product manufacturers can use this as a reference Combined with its own production conditions, cost budget, etc., choose the latex recycled rubber products produced by regular recycled rubber factories.
3. How to determine the amount of latex reclaimed rubber in natural rubber bladder
The requirements of different parts of the natural rubber bladder are different, and the specific requirements of the bladder in different use occasions are also different. When using latex reclaimed rubber to reduce the production cost of rubber bladders, rubber product manufacturers need to determine according to specific index requirements and cost budgets; the amount of latex reclaimed rubber in general bladders is controlled between 10-50 parts, and even some rubber balls Bile can completely use latex reclaimed rubber, reducing more raw material costs.
When using latex reclaimed rubber to reduce the production cost of natural rubber bladders, rubber product manufacturers not only need to choose a suitable latex reclaimed rubber, reasonably determine the amount of latex reclaimed rubber, but also need to adjust the production formula and proper adjustment of rubber bladders containing latex reclaimed rubber Production process parameters, later in time, the editor will continue to share with you other tips on reducing the cost of using natural rubber bladders with latex reclaimed rubber.
