Q:How to test the abrasion resistance of rubber?

As long as the amount of carbon black is added, the wear resistance will be increased. Have the Akron abrasion resistance test (the rubber disc shape small rubber wheels on the wheel rotating friction, turn a lap after the contrast test before and after the rubber wheel quality, poor quality of smaller, better resistance).

Q:Classification of other rubber sheets of wear-resistant rubber plates

RIT flat wear-resistant plywoodNon slip and relatively ordinary wear, usually used in less tension fabric, nylon belt, roller wrap, or ordinary environment of the drum wrapped plastic processing.RIT type wear resistant rubber plateThe surface of the rubber plate is of a rhombus shape, which has a strong anti slip and abrasion resistance. It is usually used in the fabric belt and middle and high strength steel belt and roller package processing. It is the most frequently used roller wrapped rubber sheet at present. Especially 10mm and 12mm thick rhombus rubber sheet.

Q:Rubber products on tiles, why tiles yellow?

Rubber is a mixture of substances that can precipitate and cause yellowing. The term "rubber" is called frost"

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

The glass transition temperature of natural rubber is -72 Deg. C, plastic flow temperature is 130 degrees centigrade, start decomposition temperature is 200 degrees centigrade, intense decomposition temperature of 270 DEG C. When natural rubber is vulcanized, its Tg rises, and no more viscous flow occurs.

Q:What kind of product is suitable for rubber trimmer? Where's the rubber trimmer?

Generally used for metal strip trimming, that is, after the strip of metal strips with a fixed tool to remove burr or chamfer on both sides of the required radian,Scope of application: used in tableware, stationery, hardware, sheet metal and other special equipment industry.Main functions: grinding and polishing of double sides of roll beltApplicable materials: stainless steel, copper strip, aluminum belt and other metal coil.It has the advantages of rough grinding, fine grinding and polishing. It is suitable for grinding the bevel and straight edges of metal belts of different sizes and thicknesses, and is equipped with grinding wheels and spare grinding wheels. The grinding wheel has the advantages of long service life, regular forming rules and high efficiency.

Q:Is rubber flame retardant?

Rubber itself is flammable, in the production process can be filled with some flame retardant material, it can reduce its flammability, but at the same time reduce its inherent good performance, such as abrasion resistance, elasticity, etc..

Q:What do you pay attention to when using rubber?

Water: the moisture content has two aspects: rubber in the humid air or rain soaked in water, easy to damage, this is because the rubber of water-soluble substances and hydrophilic components by water extraction solution, hydrolysis or other reasons caused by absorption. Especially in the water immersion and atmospheric exposure of alternating action, will accelerate the destruction of rubber. But in some cases water does not damage rubber and even retard ageing.

Q:What is the difference between PVC rubber and ordinary rubber?

PVC has strong resistance to oxidizing agents, reducing agents and strong acids. However, it can be corroded by concentrated oxidizing acids such as concentrated sulfuric acid and concentrated nitric acid, and it is also not suitable for contact with aromatic hydrocarbons and chlorinated hydrocarbons.

Q:EPDM rubber foam?

Three yuan ethylene propylene diene rubber (EPDM) is used as matrix, and azo two, AC and HOBSH are used as foaming agents, in order to systematically and quantitatively study the preparation process of EPDM foam material and the relationship between structure and properties of foamed material. At present, most of EPDM rubber foam material with low reinforcing carbon black filler, fine particles of carbon black can avoid the difficult problem of dispersion and high viscosity, but now the industry of light colored rubber products demand more and more, so this paper using silica as reinforcing filler rubber, studied the preparation process of EPDM foam rubber and the effects of molding conditions on the foaming process. Subsequently, the change of accelerator, filler, foaming agent and the amount of paraffin oil was analyzed. The curing properties, mechanical properties and SEM analysis were carried out, and the influence of various factors on the structure and properties of foamed material was discussed. The influence law of each formula factor on foaming is summarized, and the optimum formula dosage is expected to be found. Finally, we also through the compression behavior of stress-strain curves of EPDM rubber foam materials with different density, the energy absorption efficiency of E and I analysis of the ideal parameters of EPDM foam energy absorption characteristic of absorbing ability of W and.

Q:Does anyone know how to deal with the frosting of rubber and how to prevent it?

The situation of frost spray often occurs in rubber products, except for formulation reasons and weather. From the stage of occurrence, it may happen before sulfuration or after sulfuration.
