Rubber and its products in the long-term storage and use of the process, due to heat, oxygen, ozone, variable metal ions, mechanical stress, light, high-energy radiation, and other chemical substances and mold erosion, will gradually sticky, change Hard brittle or cracked. The factors that cause the aging of rubber are: oxygen, ozone, heat, light, mechanical stress, moisture and other factors
General plasticizer migration refers to the plastic products in the plasticizer to volatile, oozing, dissolution, etc. to migrate to the surface of the product, with the contact with the media or released into the environment. Which is involved in the plasticizer from the product to the air, the migration to contact with solid or liquid medium, and plasticizer compatibility and
Fluorescent brightener industry in the country is still a fully competitive industry. In addition, the national policy background, environmental factors can not be ignored. With the country’s strict implementation of environmental protection requirements, some poor environmental awareness of fluorescent brightener manufacturers will be more difficult to survive, and even face the risk of being eliminated because of environmental problems. Industry
The main mode of plasticizer dinch action is divided into two types, one is the plasticizer, the other is outside the plasticizer. BASF DINCH is a colorless and transparent, almost completely removed moisture, odorless liquid. It is compatible with all low molecular plasticizers commonly used in PVC. Internal plasticizer The inner plasticizer is a substance added during the polymerization of
In addition to the general rubber products, recycled rubber products are gradually come into everyone’s life. Recycled rubber is rubber products in the production of vulcanized scrap as raw materials processed into a certain plasticity, can re-use of rubber. Referred to as recycled rubber. According to the different raw materials used in waste, renewable rubber is divided into tire type,
Came into August, a titanium dioxide dragon has twice lowered product prices. It is understood that the pre-price of the enterprise is always higher than the market price, after the price adjustment, the price and the market gradually closer to the average price. After the completion of the price reduction, the enterprise take the goods stable, the product inventory pressure
Rubber additive composition analysis is based on the commission to provide materials, comprehensive utilization of qualitative and quantitative analysis means, one thousandth of the accuracy of accurate analysis of various components of the material composition, element content and filler content. The rubber and plastic raw materials and products through a variety of separation technology, the use of high-tech analytical instruments
Rubber activator is a new type of chemical product, with the traditional activator there is a very big difference. Rubber activator to a certain extent, is essential for rubber regeneration, for environmental protection has a very big benefit. Compared with the traditional, its more high-tech factors, then the rubber activator and the traditional activator comparison of what advantages? Comparison of
Although rubber additives have many types, but the added ways are mostly the same, and there are two main ways: One is the impact of dosing: the general is to reverse osmosis pressure to 0.3Mpa below, the use of drugs should be completed in 2-4 hours. The reason why this will be used, mainly due to the surface of the
The main effect of the softening agent is to soften the rubber molecules to reduce the friction between the molecules, thereby increasing the plasticity, or the raw rubber dripping agent, so that the agent easy to evenly dispersed in raw rubber. Softener can make the rubber stains and plasticity, so you can reduce the plastic refining Jane, reduce the energy
