Silicone tube plus silica with sulfide and Solutions
Silicone tube manufacturers want to in the silicone tube in Riga, white carbon black reinforcement to reduce costs; the 80 degree of silica gel with 20 phr silica is, at the same time
The 3 to 5 portions of diethylene glycol for surfactant so as to reduce the adsorption of silica vulcanizing agent, but sulfide unfamiliar, is what reason?
Is the two glycol and the silicon element in conflict or other?
Shenzhen odd silicone rubber hose manufacturers to share: silicone tube should not add two glycol, can only add a little more -2, 5 try to see! Silicone tube itself
With white carbon black reinforcement, in order to improve the structured, often with hydroxyl silicone oil, silicon rubber hose reinforcement is to use white carbon black, precipitation
And meteorological points. 80 degrees and white carbon black, a little crazy, adding silica fume can also consider under. Try to add detergent, not curing
To solve the problem, but the poor dispersion of washing powder, white spots etc. and the products of the severe deformation of sulfide. Inside don't add
Two glycol, plus a little silane coupling agent, a little more zinc oxide can also be used to subtract.
A silicone tube with two DEG, a white carbon black, with a blank, what will be the result? White carbon black with ten percent left
The right SI69 can significantly improve the performance of silicone tube. About ten percent of the silica added two glycol or polyethylene glycol can be adjusted
Acid alkali resistance, increasing the speed of curing. Separate with silica after the viscosity increases quickly, mixing and extruding operation becomes difficult, because
Silica is acidic, there may be a delay of the effect of vulcanization. So they are complementary and inseparable, or production
Out of the silicone tube is definitely not the best.
