When using reclaimed rubber to produce rubber products, reasonable use of powder materials such as carbon black, silica, nano-calcium carbonate, nano-zinc oxide and nano-clay can not only ensure product quality…
For extruded rubber products, due to the effect of moisture in the compounding agent, these extruded rubber hoses, rubber strips and other finished products may generate air bubbles. At this time, it is necessa…
Common shock absorbing rubber products include rubber air spring, rubber shock pad, ship fender, etc. adding waste tire rubber powder in proportion to different products can effectively reduce the cost of raw m…
The amount of rubber oil used in reclaimed rubber products is not small, ranging from 5 or 6 parts to more than 40 parts, which directly affects the dispersion of fillers such as carbon black in reclaimed rubbe…
Rubber rollers are mostly composed of outer rubber, hard rubber layer, metal core, roller neck and ventilation holes. The rubber part has strict requirements on the rubber material used. The rational use of rec…
Adding an appropriate amount of vulcanization activator in the production process of reclaimed rubber products can significantly increase the activity of the accelerator, reduce the amount of accelerator, and s…
As the main raw material to reduce the cost of rubber products, reclaimed rubber can be used in the production of sponge rubber products to reduce costs; choosing a suitable antioxidant can significantly improv…
There are many types of release agents, most of which are substances with low surface tension, which can form a continuous release film among the polymer and the mold. They are divided into short-life and semi-…
In addition to the inner rubber layer, the outer rubber layer and the skeleton layer, the ordinary rubber hose with a multi-layer skeleton in the rubber tube also has a filler, that is, an intermediate rubber. …
When using reclaimed rubber to produce rubber products, the coupling agent can combine organic matter with non-compatible fillers and rubber matrix to improve the dispersibility of the filler in the reclaimed r…
In actual production, sulfur vulcanization systems are selected for most of the natural rubber blends. The diffusion effect of sulfur in different rubbers is different, and the combination of vulcanization acce…
When using EPDM rubber or reclaimed rubber to produce automobile engine bearings, bridge bearings and other shock-absorbing products, the type and amount of reinforcing agents directly affect the damping perfor…
Compared with ordinary calcium carbonate, the remarkable feature of activated calcium carbonate coated with an organic active agent is that it has stronger hydrophobic properties and better compatibility with r…
Tire tread rubber is generally processed from natural rubber / styrene butadiene rubber or natural rubber / CIS butadiene rubber / styrene butadiene rubber. Proper use of waste tire rubber powder in tread rubbe…
The solubility of ordinary sulfur in rubber increases with the increase of temperature. The solubility of sulfur in different types of rubber is different. The amount of sulfur required in the production proces…
Sulfur vulcanizate has the advantages of high tensile strength, wear resistance, fatigue and crack resistance, and good dynamic and static mechanical properties. In actual production, different types of rubber …
When using reclaimed rubber to produce heat-resistant rubber products, rubber product manufacturers need to select suitable heat-resistant rubber/reclaimed rubber, and rationally design the matching system, esp…
In the production of rubber hoses, choosing appropriate framework materials can increase the strength and rigidity of the hose. Commonly used framework materials are wire and fabric. The framework materials use…
When using EPDM/butyl reclaimed rubber to prepare rubber hoses, the design of the vulcanization system directly affects the index of the finished hose, including aging resistance, compression set, etc. It is re…
When carbon black is used to reinforce butyl rubber or butyl reclaimed rubber, different types of carbon black have different effects in butyl rubber. Rubber products manufacturers should choose suitable types …
