Cov Khoom Siv Tshuaj Txhim Kho Ntawm Polyethylene

Polyethylene muaj cov tshuaj lom neeg ruaj khov, thiab tuaj yeem tiv taus dilute nitric acid, dilute sulfuric acid thiab lwm cov concentration ntawm hydrochloric acid, hydrofluoric acid, phosphoric acid, formic acid, acetic acid, ammonia, amines, hydrogen peroxide, sodium hydroxide, potassium hydroxide, thiab lwm yam. sov li Chav Nyob Kev daws. Tab sis nws tsis tiv taus cov oxidation muaj zog corrosion, xws li fuming sulfuric acid, concentrated nitric acid, chromic acid thiab sulfuric acid sib xyaw. Cov kuab tshuaj saum toj no yuav maj mam corrode polyethylene ntawm chav tsev kub, thaum ntawm 90-100 ° C, muaj peev xwm sulfuric acid thiab concentrated nitric acid yuav sai sai corrode polyethylene, ua rau nws raug puas tsuaj los yog decomposed. Polyethylene muaj kev nquag rau cov duab-oxidation, thermal oxidation, thiab ozone decomposition, thiab nws yog cov kev puas tsuaj nyob rau hauv kev ua ntawm ultraviolet rays. Cov pa roj carbon dub muaj lub teeb ci zoo tshaj rau cov ua haujlwm ntawm polyethylene. Tom qab raug cuam tshuam, hla kev sib txuas, cov saw hlau tawg, thiab tsim cov pab pawg tsis muaj peev xwm yuav tshwm sim.
