Influence of silicone oil dosage on pore structure

Silicone oil storage and transportation, use
1 Silicone oil should be stored in a dry and cool environment.
2If stored for a long time, it is good to roll on the ground for a minute or two before use.
3After opening the barrel, if it is not used up at one time, be sure to tighten the lid of the barrel after removing the material.
4 Silicone oil is a non-toxic, non-corrosive silicone surfactant, does not belong to the dangerous goods. Most varieties of silicone oil soluble in water, some special varieties may not be easily soluble in water, will be soluble in alcohols; if sticky to the skin without too much tension, wash with water can be splashed in the eyes, rinse with water and see a doctor; silicone oil can not be food to fill up, accidentally eaten or gastric lavage.

5 winter is too cold, some varieties of silicone oil will be cloudy, and even agglomeration, good baking heat to room temperature, rolling evenly after use.
6 Shelf life of silicone oil: reasonable preservation of not less than one year. Long-term storage of silicone oil, if the physical properties of normal indicators, qualified test can also be used, my company more than five years of silicone oil by the test does not affect the use.
7 take a small amount of silicone oil must be clean with special equipment. Strong acid, alkali or organic tin, etc. on the silicone oil has a destructive effect, if the mixing of such substances with the apparatus, it is likely to make the whole barrel of silicone oil deterioration.
Silicone oil market current situation
Although there are no more than ten manufacturers producing silicone oil, the current market is also quite chaotic. There is no uniform standard for quality. Polyether, blowing agent such raw materials at least have some basic standards and testing methods, but silicone oil only each manufacturer’s own standards. There is no uniform standard, the quality is not uniform, the price changes are also very large. Cheap and polyether 4110 price may be about the same, expensive seventy or eighty dollars a kilogram there.

I can give you here, the price of hard foam silicone oil in 25 to 50 yuan / kg is more reasonable, because the cost is there, believe it or not it is there! How can real silicone oil as an additive be about the same price as 4110? Basic silicone raw materials are more than 30 dollars, plus transportation, processing, silicone oil more or less to make some money! Catalyst has 4110 price? Some people say that we use silicone oil is very cheap, very cheap silicone oil I advise you to think about why silicone oil can be so cheap, why?

We all do factories, when your customers say I use other combinations of materials than your company’s cheaper than 2,000 dollars, what will you think? You will certainly think that this combination of material inside are not all glycerin ah or castor oil ah or ……… Plus polyester can not be cheaper!!!!! Some people say I’ll use someone else’s cheap stuff and it’s fine anyway. But I still want you to use the cheap silicone oil when you add 0.5 parts silicone oil at 60 ℃ baked 5 days after foaming and more expensive silicone oil to compare the change of the bubble holes, and then determine whether there is a difference between these two silicone oil. Under normal circumstances, adding 2 silicone oil may not be a problem, but we must prevent accidents. Better silicone oil, the dosage can be reduced a little bit, for the combination of material factory benefit is the same. Some people say, I dare not add less, add less for fear of problems, then you add more cheap silicone oil you are sure to add more silicone oil, not necessarily!!!! Do not dare to add less, but you dare to add cheap silicone oil!!!!
