polyethylene ua npuas ncauj txheej txheem
Seb puas xav paub polyethylene ua npuas ncauj txheej txheem?Ntawm no peb yuav piav qhia rau koj raws li hauv qab no:
Polyethylene ua npuas ncauj yog cov khoom siv nrov paub txog nws cov khoom siv ntau yam thiab ntau yam kev siv. Cov txheej txheem ntau lawm ntawm polyethylene ua npuas ncauj yog streamlined, npaum, thiab ib puag ncig tus phooj ywg.
Thawj kauj ruam ntawm cov txheej txheem tsim khoom yog extrude polyethylene pellets los ntawm lub tshuab. Cov pellets yog yaj thiab sib xyaw nrog cov tshuab tshuab, xws li hydrocarbon lossis fluorocarbon. Qhov sib tov no yog tom qab txhaj tshuaj nrog nitrogen los tsim cov npuas me me hauv cov molten polyethylene.
Cov kauj ruam tom ntej yog molding polyethylene ua npuas ncauj. Cov npuas dej tau dhau los ntawm cov txheej txheem ntawm cov chais uas ntim thiab ua rau nws xav tau cov tuab thiab cov duab. Tom qab ntawd, ua npuas ncauj yog txias thiab txiav mus rau qhov xav tau ntev.
Cov kauj ruam kawg yog sim thiab ntim cov polyethylene ua npuas ncauj. Ua npuas ncauj yog kuaj rau nws cov khoom, xws li hardness, ntom, thiab elasticity. Thaum cov npuas dej dhau qhov kev kuaj xyuas zoo, nws tau ntim rau hauv cov yob, cov ntawv, lossis cov duab customized rau kev thauj mus los thiab xa khoom.
Zuag qhia tag nrho, cov txheej txheem tsim ntawm polyethylene ua npuas ncauj yog cov txheej txheem ua tau zoo thiab txhim khu kev qha uas ua kom zoo ib yam thiab ib puag ncig zoo. Kev siv tshuab tshuab thiab cov pa roj nitrogen txo cov khib nyiab thiab emissions. Raws li qhov kev thov rau polyethylene ua npuas ncauj txuas ntxiv nce, cov txheej txheem tsim khoom yuav txuas ntxiv txhim kho thiab hloov kho kom tau raws li qhov xav tau ntawm ntau yam kev lag luam.
