Qhov zoo ntawm Epoxy Polyester Hybrids Hmoov Txheej

Epoxy hmoov txheej raws li cov thev naus laus zis tshiab hu ua epoxy-polyester "hybrids" lossis "multipolymer" systems. Cov hmoov txheej no tuaj yeem suav hais tias tsuas yog ib feem ntawm tsev neeg epoxy, tshwj tsis yog tias feem pua ​​​​ntawm cov polyester siv ntau (feem ntau ntau dua li ib nrab ntawm cov resin) ua rau qhov kev faib tawm tsis raug.
Cov khoom ntawm cov txheej txheej hybrid no zoo sib xws rau epoxies dua li polyesters, nrog rau qee qhov tshwj xeeb. Lawv qhia tau zoo sib xws nyob rau hauv cov nqe lus ntawm kev cuam tshuam thiab khoov tsis kam, tab sis tsim me ntsis softer films.Lawv corrosion kuj yog piv rau epoxies nyob rau hauv ntau rooj plaub, tab sis lawv kuj rau cov kuab tshuaj thiab alkali yog noob.rally inferior rau ntshiab epoxy.

Ib qho txiaj ntsig ntawm cov hybrids no, vim muaj kev cuam tshuam ntawm polyester tivthaiv, yog siab tiv thaiv kom dhau-ci daj hauv qhov cub kho. Qhov no kuj txhais ua qee qhov kev tiv thaiv zoo rau ultraviolet lub teeb daj. Cov tshuab no yuav pib chalk yuav luag sai npaum li cov epoxy tab sis, tom qab pib chalking, qhov deterioration qeeb qeeb thiab cov xim tsis muaj zog tsawg dua rau cov hmoov epoxy tsis hloov.

Lwm qhov zoo dua ntawm epoxy / polyester hmoov txheej yog lawv cov yam ntxwv zoo electrostatic tsuag. Lawv tuaj yeem siv nrog kev hloov pauv zoo heev thiab pom zoo nkag mus rau hauv cov ces kaum thiab qhov chaw so.An epoxy polyester hybrid yuav tsum tau txiav txim siab nrog rau tsev neeg epoxy rau nyias zaj duab xis zoo nkauj kawg siv. Daim ntawv thov rau epoxy polyester hybrid yog teev nyob rau hauv daim duab 2-3; cov khoom raug muaj nyob hauv daim duab 2-4.
