Storage and transportation, use of silicone oil
Silicone oil should be stored in a dry and cool environment.
If it is stored for a long time, roll it on the ground for one or two minutes before use.
After 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.
Silicone oil is a non-toxic, non-corrosive silicone surfactant and is not a hazardous material. 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 to see a doctor; silicone oil can not be food to fill up the hunger, accidental ingestion or to wash the stomach;
Winter is too cold, some varieties of silicone oil will be cloudy, and even lumps, baking heat to room temperature, rolling evenly after use.
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.
Take a small amount of silicone oil must be clean with special equipment. Strong acid, strong 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, you 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 use other people’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!!!! Add less dare not, but you dare to add cheap silicone oil!!!!
Cheap vegetables, nine times out of ten is gutter oil fried; cheap rice is likely to be added plastic particles; cheap noodles may be added talcum powder. I don’t know whether you believe it or not, I do believe it!!!!
Synthesize the above:
Silicone oil in the combination of materials or foaming process is a key additive, with not much, the role is not small, no silicone oil is to collapse the bubble, silicone oil failure is also to collapse the bubble.
Silicone oil quality and price is related, the price is worth every penny, you want to buy meat with the price of tofu, the possibility is very small, you are smart, others are not stupid.
The role of silicone oil: emulsification, nucleation, bubble stabilization, flow.
Silicone oil selection, in the procurement of silicone oil must indicate your purpose, silicone oil manufacturers can according to your requirements and the characteristics of their company products to help you choose the right product.
Silicone oil test: silicone oil test with the reduction method to do application experiments, so that more representative, the apparent physical properties of the index does not represent the actual role of silicone oil.
Silicone oil dosage: polyether + polyester 1.5-3.5%, our company’s silicone oil we generally recommend the dosage of 1.5 ~ 2.5%;;
Combined material such as problems do not jump to conclusions, do not say it must be a silicone oil problem. To seriously analyze, I suggest that each engineer to develop good habits, every time the raw materials to come to the clean apparatus to seal the sample. So that even after the problem, you can take out the sealed samples to analyze one by one, otherwise find the problem but can not find the root cause, which is not anxious! Before you ship, your own products should also be done to observe the stability of the sample, customer complaints can also be analyzed when the original!
