Silicone sports bottle, silicone cosmetic bag is made of silicate polycondensation, avirulent insipidity, chemical performance is very stable, not any response from the acid and alkali salt.
Because the silicone is colloid structure, has a number of microporous and, for water has a strong absorption ability.
So silicone sports bottle, silicone cosmetic bag can be used as food, medicine, daily necessities of the desiccant for external use only, because the silicone is after refining of raw materials production and sterilization, and won't have side effect to human body.
The secret of the silicone sealant out cheap white oil really good white oil for what?
The end of the 19th century, to start producing white oil abroad, the use of concentrated sulfuric acid or oleum sulphonation method, the method of shortening the quality is not stable, low yield, raw material loss is big, acid consumption quantity is big, difficult to deal with a large amount of acid slag, environment pollution is very serious.
Later sulfur trioxide sulfonation method process, the acid consumption greatly reduced, the white oil yield increased, but the environmental pollution problem is still not solved.
White oil commonly known as paraffin oil, white oil, mineral oil, is often by the crude oil pressure and vacuum fractional distillation, solvent extraction and dewaxing, hydrofining and (
Figure, mainly for saturated naphthene mixture with paraffin.
As shown in the figure 1.
It has excellent oxidation stability, chemical stability, light stability, colorless, tasteless, no corrosion fiber fabric.
At the beginning of 20 century 60 generation, hydrofining technology applied in the white oil production.
Hydrofining technology environment pollution is small, white oil yield is high, the quality is stable, and can in the production of high viscosity, high grade white oil, since white oil had leap to improve the quality and yield.
The core reason: reduce cost and obtain more benefits.
Because of dimethyl silicone oil price is quite high, as the sealant industry market competition heats up, some silicone seal manufacturers to reduce costs, from the perspective of the plasticizer, using white oil instead of dimethyl silicone oil as plasticizer of silicone sealant, made of silicone rubber is referred to as 'white oil glue'.
On the surface, these low-cost 'white oil filling glue' and not white oil filling silicone sealant has no much difference, some products even do look very good, very bright, fast curing speed, initial curing mechanics performance is good too.
But with longer duration of use, 'white oil filling glue' and not white oil filling silicone sealant differences will gradually revealed.
As shown in the figure 2.
Silicone sealant is mainly composed of organic silicon based polymer, fillers and additives of three parts, silicone sealant has excellent weather resistance is mainly composed of silicon -
Organic silicon based polymer of silicon key chain, if cut down the content of organic silicon based polymer and its durability will be severely affected.
Which of the three, the content of organic silicon based polymer is high, the unit price is high, the cost more than 70% of the cost of the silicone sealant.
In order to reduce the cost of sealant, many sealant manufacturer will increase the amount of filler, adding mineral oil instead of part of the silicone oil, thus reducing the content of organic silicon based polymer.
What harm shortening shortening glue and silicone sealant system compatibility is poor, the shortening is added in the silicone sealant easily from the silicone sealant system migration, infiltration, leading to silicone sealant weatherability, eventually make the above all kinds of serious harm.
'White oil glue belong to inferior product, although the price is low, but once appear problem, late rework costs, maintenance costs, damage to the brand the price will be the purchase cost of several times or even more, not only cost savings, instead of add extra costs, not worth!
Remarks given the first listed countries, France is usually a new iphone so as starting state of the United States, Britain, Germany, Australia, Japan, etc. , should also can reserve a new iphone in September 11.
Last week, the German operators have released in advance iphone6s release information, said it would open sell on September 18th.
Silicone commodities, 'to provide customers reliable high-quality green products.
And silicone rubber products factory all along receives 'is jiahao honey production concept.
Company adopts advanced erp management system, and in accordance with the relevant institutions, laboratories, professional testing company and well-known listed companies have good relations of cooperation, set up its own quality inspection system.
Silicone rubber can be used ordinary rubber processing equipment for processing, but should pay attention to: keep clean processing, can not be mixed with rubber, oil or other impurities, otherwise it will influence on the performance of the silicone rubber vulcanization and;
Silica gel products should be carried out in the oven hot air for a long time the second period of sulfide, in order to improve the performance of the vulcanizates.
Organic silicon good physicochemical properties for the new demand such as new energy, electronic, 20 years, better global demand to maintain growth, starts a steady climb, 20 -
27 of three phase starts each 78%, 80% and 82%.
Organic silicon monomer production capacity in China accounted for 52% of the world's total capacity.
Organic silicon monomer production capacity at home and abroad such as shown in figure 4.
In contrast, China, safety standards set by the government and the enterprises or emission standards actually standards higher than basf.
'But if you want to get the identity of the society, then your standards themselves must do it.
'KeDiWen told caijing reporter said.
