In the production of rubber products, the use of calendering machine or extruder preformed in a variety of shapes, different sizes of the process, called the molding. Forming methods are: Rolling is suitable for the manufacture of simple sheet, plate products. It is the compound by pressing the press pressed into a certain shape, a certain size of the film
With working and development of the rubber aging process, rubber and its products will gradually reduce the performance or complete loss its value. In order to extend the service life of rubber products, it is necessary in the rubber with some of the material can inhibit the aging process, thereby extending the rubber and its products storage period and service
With the development of society, the use of dispersants has also been more and more attention. The effect of the dispersant is to reduce the time and energy required to complete the dispersion process using a wetting and dispersing agent, to stabilize the dispersed pigment dispersion, to modify the surface properties of the pigment particles, and to adjust the movement
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
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
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
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
Deodorant is a chemical agent used to eliminate, reduce or cover the odor, according to the use of different can be divided into many types, can effectively reduce or eliminate the rubber additives and rubber itself residual monomer caused by the smell or odor, especially Suitable for some use of secondary re-processing of rubber products. Rubber deodorant has excellent temperature
