Will make the resource optimize configuration, often mixed let 1 + 1> 2.
So the Thai rubber insulation kraal mat think, fluorine rubber 'mixed doubles' is necessary.
Then the specific how to operate?
Recycle: in front of the preform and the mold, should be on a clean mixing machine thermal refining.
When cooking without a BoTong, rubber soft package after roll forming good to the piece.
Just a piece of rubber do not overlap, can overlap place after cooling to room temperature.
Preforming: according to the mould and product requirements, type of film into the size, shape, and reset the consistent preforming, guard against all kinds of possible pollution in the process of preform.
Then, mixing of rubber oil seal rubber is fully consider when making and metal skeleton and sex, the surface of the metal frame processing is a must.
It is recommended to use adhesives have Thixon, Chemlok 5150 300/301.
Mold: mold had better be chrome plated or high hardness.
Appropriate when moulded in spray mold release agent will get better demoulding effect, moulding temperature 160 ℃ ~ 190 ℃, moulding is commonly 3 ~ 7 minutes, depending on the thickness of the products.
Process may be with the actual processing technology is different, suggest adjusted according to the actual situation.
Sulfide: need to have secondary sulfide fluorine rubber products, to the best of the physical and chemical properties.
Usually curing conditions of 230 ℃ @ 16 ~ 24 h, then, if the widget is and metal is recommended 200 ℃ @ 16 ~ 24 h, should have two period of curing oven blast device, able to maintain constant temperature, secondary vulcanization of volatiles in time.
Mr Tai insulation rubber kraal mat tips, product through the packaging form to avoid pollution and absorb moisture, in the use of the operating process in the future, should also avoid the possible problems, shall be sealed after each processing, processing and storage, appropriate mixing rubber storage life can be more than six months, stored without refrigeration, but storage temperature should be below 30 ℃, excessive temperature will significantly accelerate the curing speed and reduce the coke burning resistance.
Contact with sulfur will affect vulcanization system, cause air bubbles or reduce the curing speed, 0.
25 sulfur even entirely prevent sulfide.
