Current, ester technology develops colophony of domestic and international not saturated polyester and annulus oxygen vinyl faster, phyletic and various, include most commonly used adjacent benzene colophony is mixed vinyl of oxygen of a benzene colophony, annulus ester colophony, but above of make a comprehensive view kinds of each are big not saturated colophony, the colophony choice when the user is deciding to be used at specific application circumstance is not much. Usually, choice adjacent benzene not saturated colophony or benzene not saturated colophony is made with the FRP at convention, choose vinyl ester colophony to be used at having high strength requirement or anti-corrosive the composite material of the circumstance is made, but, cost of vinyl ester resinous is relative taller, in a few blame anti-corrosive when the circumstance has the composite material that high mechanical performance asks to make, at present domestic and international client can choose colophony of annulus oxygen vinyl only.
This kind of new-style high-powered not saturated colophony that research and development of limited company of chemical industry of Shanghai rich morning rolls out, call vinyl polyester colophony (Vinyl Polyester Resin, abbreviation “VPR“) , this colophony is integrated vinyl ester colophony and characteristic of general not saturated resinous, let an user have more choices thereby.
Shanghai rich morning produces base
Colophony of VPR vinyl polyester is the colophony of not saturated polyester of the special structure that a kind of dissolve contains not saturated Shuang Jian at styrene fluid, colophony of VPR vinyl polyester is had better be able to bear or endure corrode function, the benzene between excel not saturated colophony, mechanical function and colophony of vinyl of oxygen of standard type annulus comparative, especially fatigue resistance can be mixed dynamic load function; Additional, more general colophony, polyester colophony has VPR vinyl to be able to bear or endure goodly again await function, at the same time colophony of VPR vinyl polyester has good Bo towing tie again infiltration function and technical properties, agree with all sorts of FRP shape craft, include fiber to twine, help all sorts of composite material technology such as paste of crowded, hand, eject.
Rich morning colophony
Colophony of VPR vinyl polyester is had in the characteristic of low viscosity, with colophony of a general benzene not saturated polyester or annulus oxygen vinyl ester colophony as good as, watch 2.1 in listed index of convention of resinous of VPR vinyl polyester.
Express index of 2.1 liquids resinous (25 ℃ ) :
2.2Resinous of VPR vinyl polyester is mechanical function
Colophony of polyester of vinyl of VPR of rich morning series has the mechanical property that comparatives with vinyl ester colophony, have good tenacity and fight fatigue character, have higher outspread rate more, we are right ester colophony undertook colophony of a current and commonly used benzene not saturated polyester and standard type vinyl mechanical function is compared, watch 2.2 in listed concerned function compares a list.
Express character of physics of body of 2.2 colophony mould to compare (25 ℃ )
2.3Corrosion resistance of resinous of VPR vinyl polyester can
While colophony of VPR vinyl polyester can provide the mechanical performance that with annulus oxygen vinyl ester colophony comparatives, also have good anti-corrosive characteristic, colophony of more general not saturated polyester is better anti-corrosive characteristic, watch 2.3 in listed, resinous of VPR vinyl polyester a few convention are anti-corrosive characteristic.
Resinous of polyester of vinyl of watch 2.2 VPR-01 is anti-corrosive characteristic
Note: 1, ALL—Express ” of “100% chroma ” or “ saturated solution, NR—State “ is not recommended;
2, when glass reinforced plastics is made, especially alkali resistance circumstance and other are strong corrode a circumstance, the solidify after should undertaking is handled;
3, the confine as a result of experiment condition, our company provided groovy chemical medium only be able to bear or endure lukewarm data.
Product of rich morning series, buy variety for add lustre to of each industry user
