In modern industry production, colophony is applied extensively at each domains, wait like building, car, electron, aviation, medical treatment. Colophony regards a kind of high polymer as material, have superior mechanical performance, chemical function and treatment property, because this equipment accepts industry favour. However, the colophony function of different sort each different, we need to undertake comparative to its, so that suit the colophony of own demand most in the choice when using. Above all, we need to understand characteristic of function of different and phyletic resinous. For example, epoxy resin has extremely powerful sticky resultant force and corrosion resistance, apply to all sorts of metals and metalloid material stick receive and coating; Polyamide colophony has superior mechanical performance and high temperature stability, there is wide application in the domain such as aviation and car; Polycarbonate colophony has admirable transparency and tenacity, apply to optics and electronic domain. Characteristic of function of different and phyletic resinous each are not identical, need undertakes choosing according to effective demand. Next, we still need to consider resinous to machine function. Colophony needs to consider its melt temperature, fluidity and solidify time to wait for an element when treatment. For example, thermoplastic colophony has inferior melt temperature and better liquidity, can wait for a method to undertake machining through noting model to shape; And solidify undertakes below the temperature with heat up solid sex colophony to need to be in constant, treatment difficulty is greater. Accordingly, when choosing colophony need considers its machine function, so that have manufacturing treatment better. Finally, we still need to consider resinous cost and environmental protection sex. Do not differ with phyletic resinous cost bigger, need undertakes choosing according to effective demand; In the meantime, we also need to consider sex of resinous environmental protection. Current, the state is stricter and stricter to standard of resinous environmental protection, we need to choose to accord with the colophony of environmental protection standard, in order to reduce environmental pollution.

Anyhow, colophony regards a kind of important high polymer as material, the effect that cannot replace is being produced in modern industry production. When choosing colophony, we need to understand different sort the element such as function of resinous function characteristic, treatment, cost and environmental protection sex, so that choose to suit the colophony of own demand most, serve to develop at the industry better thereby. In addition, resinous is used also need to notice its apply setting. Different setting needs different colophony, for example car component needs to have the property such as caustic of high temperature resistant, wear-resisting, and housing materials needs to have be able to bear or endure await gender and corrosion resistance. Accordingly, when choosing colophony need considers his to apply setting, with developing its performance dominant position adequately. Want to choose the colophony that suits most, we need to undertake function checks with the experiment quite. Check through the experiment, we can understand resinous the expression of the respect such as mechanical function, corrosion resistance, hear resistance. Compare through function, we can understand different sort resinous actor defect, undertake choosing thereby. Besides, we still need to consider the factor such as efficiency of manufacturing cost, production, so that serve better,develop at the industry. Anyhow, resinous function is a complex process quite, need considers the factor of many respects. In modern industry production, resinous application range is wider and wider, accordingly we need to rise to understand and be known to resinous ceaselessly, with answering all sorts of production demand better, make larger contribution for industry development.
