Q:How to improve the hardness of rubber?
General 90SHA or more need to use hard resin or high styrene such things, of course, have to properly adjust the strengthening agent and curing system
Q:Why is natural rubber a strategic material?
Standard rubber: standard rubber is mainly divided into 5 glue, No. 10 glue and No. 20 glue. Glue No. 5 is the first grade glue. It is the best glue. Its impurity is 0.05%; No. 10 glue is two grade glue, its impurity is 0.10%, 20 glue is three glue, and its impurity is 0.20%. Glue uses different models are not the same: No. 5 commonly used to make rubber tyres; No. 10 and No. 20 rubber glue for making tire.Smoke film: the natural film pressure to the water were smoked after baking film by burning the coconut shell by smoke and heat. The purpose of fumigation is to make the film dry and inject anti oxidation and antiseptic cresol substances. Natural rubber is the primary form of smoke film.Concentrated adhesive: it can be used as bonding material.
Q:What kind of material does the shockproof rubber cushion usually choose, What's the hardness?
Recommend the use of EPDM, its good elasticity, although lower than natural rubber, isoprene rubber and butadiene rubber but its resistance to aging, corrosion resistance, chemical resistance, resistance to high pressure steam performance advantage, so compared to choose EPDM.Shock absorbing rubber used to be the only adhesive for NR in the past. In recent years, in order to meet the requirements of increasing heat resistance and oil resistance of automobiles, IIR, EPDM, NBR and CR have also begun to be used, and even microcellular PU elastomers and TPE thermoplastic elastomers have appeared. In addition, according to automotive requirements, in order to achieve lightweight targets, plastics have begun to replace metal, so-called rubber and plastic shock absorption rubber products.
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:What about rubber molding, foaming and layering?
Foaming1 vulcanization is not sufficient, the temperature is too low or time is too short, so that the volatile compounds produced during curing have not been cleaned out;2, under the pressure of vulcanization, the trapped gas and sulfur volatile matter can not be discharged in time3, there is air or moisture in the glue;4, curing temperature is too high, the surface of the gum material premature vulcanization, hindered the glue material in the steam, air free precipitation5 vulcanization speed of material is too fast
Q:How do rubber undergo vulcanization?
Heat vulcanization can be divided into three methods: direct vulcanization, indirect vulcanization and mixed gas vulcanization. Direct vulcanization; vulcanizing in hot water or steam medium. Indirect vulcanization, vulcanization in hot air. Third, gas vulcanization, first vulcanization with air, and then direct steam vulcanization.
Q:How can rubber products prevent fading?
That is to add UV absorbers, white, then add more titanium dioxide, there is no good way, as well as your choice of pigment, as far as possible difficult to fade, such as inorganic pigments.
Q:I do rubber products, I would like to ask what metal accessories are rubber products, the specific name is what, good, then points
Silica gel tube, other rubber tube, clip fabric hose, braided hose, oil resistant hose, special hose, winding hose, industrial rubber, rubber products, insulating sleeve
Q:What are the rubber parts for the car
There are many, such as tires, car wipers, brake pads, gaskets for high temperature parts such as engines, air springs (for shock absorption), seals
Q:How can I get rid of the rubber?
You smell the smell from the vulcanized rubber residues, not much of the flavor is generally placed in a cool ventilated place, you can, and if the smell is large, you can use rubber deodorant, supermarkets generally sell
