Q:Properties and specific uses of various rubbers

Natural rubber is mainly derived from the Hevea tree. When the epidermis of this rubber tree is cut open, it will shed milky juice. It is called latex, and the latex will be natural rubber when it is condensed, washed, molded and dried.

Q:The action of various ingredients in rubber formula

Performance system: reinforcing agent, colorant, foaming agent, fragrance agent, hardening agent, plasticizer, flame retardant, antistatic agent

Q:How can rubber products prevent fading?

Light and white rubber products are prone to yellowing in the course of use and storage, thus affecting appearance and quality, resulting in various economic disputes and irreversible losses.

Q:What's the difference between natural rubber and three yuan ethylene propylene rubber?

The main use of natural rubber natural rubber because of its insulation, plasticity, water vapor barrier, tensile and wear characteristics of strong elasticity and good, widely used in industry, agriculture, national defense, traffic, transportation, machinery manufacturing, medical and health fields and daily life, such as transportation with the tire industry; with the transport belt, transmission belt, sealing rings; medical gloves, transfusion tube; used in the daily life of the shoes, raincoats, warm water bag are rubber as the main raw materials manufacturing, defense on the use of aircraft, artillery, tanks, and cutting-edge technology in the field of rockets, satellites, spacecraft, space shuttle requires a large amount of rubber parts.

Q:Can rubber products be injection molded and plastic injection functions?

Injection molding is a method of producing shapes in industrial products. Products are typically molded by rubber injection and plastic injection. Injection molding can also be divided into injection molding. Die casting method. Injection molding machine (referred to as the injection molding machine or injection molding machine) is plastics molding equipment of thermoplastic or thermosetting material using plastic mold made of various shapes, injection molding by injection molding machine and mold.

Q:Rubber rolling process for making rubber products

Calendering equipment: calender, calender, by roller, frame and bearings, pitch device, roller deflection compensation device, as well asAuxiliary pipe device, motor drive mechanism and thickness detection device and other components.

Q:Rubber and metal have to be sealed before they are too strong

The percentage difference between the first compression compression = original section diameter minus the trench size divided by the original O ring diameter O-ring compression is mainly depends on the material hardness and O-ring, O-ring if the hardness is 70 degrees, then the O-ring compression is equal to 20%. Of course, the lower the hardness of the O-ring, O-ring compression is greater, mainly used for low pressure places. Then the O-ring hardness increases the amount of compression of the O-ring is smaller, mainly used for high pressure, pressure resistance, resistance of small environment. And so on, the amount of compression can be any hardness O-ring you need.

Q:Advantages and disadvantages of rubber products

Natural rubber NR(Natural Rubber) rubber made by collecting latex, is isoprene polymer. With abrasion resistance, high elasticity, tensile strength and elongation as well. Aging in the air, hot sticky, easy expansion in mineral oil or gasoline and dissolved, but not resistant to strong acid and alkali. Advantages: good elasticity, acid and alkali. Disadvantages: not weather, not oil resistant (resistant vegetable oil) is the production of adhesive tape, rubber hose, rubber material, and is suitable for the production of damping parts, brake products using oil and ethanol in the liquid with hydroxyl in the car.

Q:Process for producing rubber products

Rubber elastic, lack of necessary processing plasticity properties, therefore not easy to process. In order to improve the plasticity, so the rubber mastication, so the mixing of ingredients easily dispersed in rubber, which also helps to improve the permeability of the fabric into rubber and molding in rolling and molding process. The long chain molecular degradation were called plasticity forming process of mastication. Mechanical plastication and mixing two kinds of thermoplastic plastic mixing method of rubber. Mechanical plasticization is the reduction of long chain rubber molecules at shorter temperatures through the mechanical extrusion and friction of the extruder, which changes from a high elastic state to a ductile state. Hot hot mastication is to pass into the rubber in the compressed air in the heat and oxygen under the effect of the degradation of long chain molecules to obtain shorter plasticity.

Q:How should the rubber products be dirty?

First coated with vinegar on the top, after dry, and then wipe paper, so clean
