玻璃钢管道结构上分内衬层、结构层及外保护层三部分。其中，内衬层树脂含量高，一般在70％以上，其内表面富树脂层树脂含量高达95％左右。通过对内衬所用树脂的选择，可使玻璃钢管道在输送液体时具有不同的耐腐蚀性能，从而满足不同的工作需要；对需外防腐的场合，只需对外保护层树脂进行认真选择，便也可达到不同外防腐的使用目的。 The structure of glass steel pipe is divided into three parts: lining, structure and outer protection. Among them, the lining layer resin content is high, generally in over 70%, the inside surface rich resin layer resin content is as high as 95%. Through the selection of resin in lining, it can make the fiberglass pipe have different corrosion-resistant properties when transporting liquid, thus satisfying different work needs. In the case of an antisepsis, a careful choice of the outer protective layer resin can also be used for different anti-corrosion purposes. 　　根据不同的腐蚀环境，可选用不同的防腐树脂，主要包括：间苯型不饱和聚酯树脂、乙烯基树脂、双酚a树脂、环氧树脂及呋喃树脂等，根据具体情况分别选用：对酸性环境，选用双酚a树脂、呋喃树脂等；对碱性环境，选用乙烯基树脂、环氧树脂或呋喃树脂等；对溶剂型使用环境，选用呋喃等树脂；当酸、盐、溶剂等腐蚀不是十分严重时，则可选用价格较为低廉的间苯型树脂。通过对内衬层不同树脂的选择，便可使玻璃钢管道广泛用于酸、碱、盐、溶剂等工作环境中，表现出良好的耐腐蚀性能。 According to the different corrosion environments, can choose different anticorrosive resin, mainly includes: between benzene type unsaturated polyester resin, vinyl resin, resin and bisphenol a epoxy resin and furan resin, etc., selected according to specific circumstances, respectively: the acidic environment, choose bisphenol-a resin, furan resin, etc.; For alkaline environment, choose vinyl resin, epoxy resin or furan resin, etc. For the use of solvent, the use of resin such as furan; When the corrosion of acid, salt and solvent is not very serious, it can be used for the lower price. Through the choice of different resin lining layer, and can make the glass fiber reinforced plastic pipeline is widely used in acid, alkali, salt, solvent, such as work environment, shows good corrosion resistance.
