Q:How to make rubber products keep brightness for a long time?

Keep it in the right place: ventilated, dry place, not squeezed

Q:How can I make rubber products brighter?

Special release agent for rubber products, release agent.Mold release agent is an interface coating used on two surfaces that are easy to adhere to each other. It can make the surface of the material easy to break off, smooth and clean. Mold release agent is used in various molding processes, such as glass fiber reinforced plastics, metal die casting, polyurethane foam and elastomer, injection molding thermoplastic, vacuum foaming sheet and extrusion section. In molding, sometimes other plastics, such as plasticizers, leak to the interface, and then a surface remover is needed to remove it.

Q:Excuse me, what is in the rubber rubber, glue them, what is the difference?

The toughness greatly improved than rubber glue. If the car tire is cooked. Generally the same thickness, soft as glue.

Q:Is sandal rubber bottom good or polyurethane good?

Rubber material itself poor ventilation, long wearing easily lead to beriberi. And summer rains, if the rain does not drain, will add story.

Q:What kind of materials should be used for rubber products to keep the brightness of the mirror for a long time?

To make high gloss products, first of all, there must be good raw materials, followed by a good stain, high light color powder, to achieve free spraying, high light injection molding, first of all need to use high gloss plastic material.

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

Different materials and O-ring O-ring compression the change of general material such as NBR, NR, nitrile rubber, natural rubber, chloroprene rubber CR, EPDM three EPDM, HNBR hydrogenated nitrile rubber, silica gel SILICOME SBR Buna, styrene butadiene rubber, SBR, acrylate rubber ACM, compression O-ring or the 20% to calculate. If it is a special material FKM, VITON, PU, FLS silicon fluorine rubber, fluorine rubber, polyurethane, compression of these materials is calculated by 15% o ring.

Q:What is the pressure on rubber products during vulcanization?

It can be seen that the vulcanization time can be shortened by increasing the sulfuration temperature. The process of high temperature vulcanization is injection vulcanization and electric heating flat vulcanization. Both of them can be cured at 160 DEG C or even higher. In recent years, the industry has also adopted the trend of high temperature vulcanization. In addition, the continuous vulcanization process using eutectic liquid as heating medium has also begun to use high temperature vulcanization. In the rubber injection molding process, because the rubber material has passed the preheating and plasticizing of the screw, higher vulcanization temperature (such as 175~183 DEG C) can be adopted, but the reversion or sulfuration of rubber is less affected. For example, for three yuan ethylene propylene rubber, when set 160 degrees for molding, the positive curing time is 60min, if it is changed to 200 degrees noteThe time of vulcanization is only 4min. With the use of general-purpose rubber to make small products, the vulcanization time can be l-2mm.

Q:How to improve the aging resistance of rubber?

In the course of oxidation, ozone can produce molecular cracks, but also make the deformed rubber crack in the direction of stress, namely ozone cracking".Heat will increase the temperature, thermal cracking or thermal crosslinking of rubber will accelerate the oxidation rate of the rubber, that is, heat aging.

Q:Rubber products are not allowed to touch oil products, but why can rubber gloves be contacted daily? What's the point?

Most rubber materials are not resistant to oil, some rubber materials are resistant to oil, such as nitrile rubber, etc., the family commonly used detergent on rubber gloves did not affect.

Q:Rubber products labeled Huai gum can improve wear?

Today, white carbon (silica) is added to the tread formula, which is not for abrasion resistance, but for skid resistance of wet pavements, and is resistant to cutting in truck tires.
