High-performance rubber 2009-04-09 2153
May wipe ink, ballpoint pen oil
Rubber, is a petty thing. Some people may think that not worth talking about. In fact, for an engineering and technical personnel, or member of tracing people who often use pen and ink, is indispensable supplies.
Here the effect of a very good rubber. This rubber can easily erase writing, stains do not stay and would not cut through the paper, always keep the original base map it will not only erase pencil, pen writing, but also erase ball pen ink and oil trace.
This rubber is a thermoplastic resin, plasticizers, filling agents, stabilizing agent composition of the rubber substrate, with a boiling point above 120 soluble resin made from detergents and foaming agents.
As a thermoplastic resin used are polyvinyl chloride, polyethylene, vinyl acetate copolymer, polybutadiene, etc..
As a plasticizer were octyl phthalate, dibutyl phthalate, octyl adipate, dibutyl adipate, such as chlorinated paraffin.
As a filler are calcium carbonate, diatomaceous earth, barium zinc white, barium sulfate, clay and so on.
As a solvent are milk methyl ester, triethanolamine, formamide, N-dimethyl formamide, etc.. In addition, there are diethylene glycol, ethers and ketones, acid-soluble fiber B agents, such as dimethyl amide.
Were used as a blowing agent NN39-2-nitroso-N N39-dimethyl-terephthaloyl amide, azo-bis-isobutyronitrile, 4.4 39- dihydroxy - bis phenylsulfonyl and wholesale jewelry so on.
The above-mentioned thermoplastic resin, plasticizers, filling agents, stabilizing agent to be mixed through the mixer, using the processing procedures of plastic rubber Reinforced with foam molding.

Special materials to the above mixture, add 1 surfactant, N-dimethylformamide 60, a mixture of 40 together with the blowing agent. Above 120 in a mixture of the first five minutes pressurized, 165 after 5 minutes and then compression molding can be. Mold can be designed in accordance with requirements of shape, but also by adding in different colors.
Japanese technology
High-performance rubber which can wipe ink, ballpoint pen oil
The effect of the domestic rubber generally poor, can only erase pencil marks. Of the pen, ball-point pen through the use of the handwriting is similar to hydrogen peroxide, bleaching powder, sodium oxalate and other substances to improve. We recommend the production process is the replacement of existing stationery rubber new products, market considerable economic benefit.
Cost estimates 20 grams per block of Budget, Accounting and rubber 50 per kilogram, per ton base material can be suppressed 50000 rubber. According to use and consumer psychology can be turned into 5 grams, 10 grams of weight and other rubber and pressed into 200,000 and 100,000.
Retail price of each rubber 7 pm 5 g tons of output value of 14,000 yuan.
Ton cost of 7100 yuan, 5 grams cost 3.55 grams.
Annual output of 100,000,000 100,000,000 -1.5 rubber output value 10.5 million yuan to 7,000,000 yuan, around like all the costs, each weighing five grams rubber net profit was 1 minute, can be one million yuan.
