Phenolic aldehyde data is other shape technology

Complex material still has phenolic aldehyde successional lamination shapes technology, fiber surrounds shape technology, beforehand technology of macerate mould pressing, low-pressure mould pressing shapes paste of technology, hand shapes technology, spray shapes the technology shape method. Hand burnt technology is abroad's most commonly used phenolic aldehyde glass reinforced plastics produces one of technologies.

Choose colophony of acerbity solidify phenolic aldehyde commonly, its activator dosage is 5% ～ about 8% , is viscosity 600-700mpa about? S. Join activator, can drop commonly resinous viscosity, solidify hour is 10 ～ 30min about, even a few shorter than polyester resinous. Carry out a proof, need to pass serious Tu Fu only, can make so that measure compares steel of big phenolic aldehyde glass. The product with good coating, answer to undertake solidify below proper temperature. As a result of short the certain coupling agent that cuts former silk felt, cannot dissolve at phenolic aldehyde colophony, not be all consequently apply to polyester resinous fibre glass, can apply to phenolic aldehyde colophony.

Hand paste shapes the steeliness of phenolic aldehyde glass that the law produces, measure is OK very big, for example the cab of train of tunnel of the English Channel, every amount to 240kg. Changshu carries in the development of this respect good precedes at home position.

Other, the carry dosage that colophony of foreign spray phenolic aldehyde prevents heat board respect in the car is very big also. A lot of produce the manufacturer often chooses the colophony of medium viscosity phenolic aldehyde near as burnt as the hand technology, but mix have stronger activator, shape in order to accelerate its speed, cut down shape always. When colophony of spray phenolic aldehyde, be necessary to be improved slightly to the machine of spray polyester, and cannot use exterior mixture spray gun, request the activator volume that activator pump carries, those who reach colophony volume 10% the left and right sides, its spray component is necessary to be able to be able to bear or endure of chemical corrode.
