PE yeeb nkab yog tsim los ntawm polyethylene raws li lub ntsiab raw, ntxiv antioxidant, carbon dub thiab cov ntaub ntawv coloring. Nws yog yam tsawg los ntawm kev ceev, qhov siab muaj zog, tsis kub thiab tsis muaj zog, thiab kev kub hnyiab ntawm -80 ° C.
PE yeeb yas tuaj yeem ua tiav los ntawm ntau txoj hauv kev los ua ntau yam khoom xws li cov yeeb yaj kiab, ntawv, yeeb nkab, profile, thiab lwm yam .; thiab nws yog ib qho yooj yim mus txiav, nyiaj txiag thiab "weld". Cov yas yog ib qho yooj yim rau xim thiab tuaj yeem ua rau ntau hom xim ci. Nws tseem yuav ua tiav los ntawm luam tawm, electroplating, printing thiab embossing, thiaj li hais tias cov yas muaj ib tug nplua nuj hniav zoo.
Cov tshuaj feem ntau yog cov tshuaj tiv thaiv ntau dua cov acids, alkalis, ntsev, thiab lwm yam tshaj li cov khoom siv hlau thiab qee cov ntaub ntawv inorganic. Lawv yog cov tsim tshwj xeeb rau cov qhov rooj, qhov rais, cov plag tsev, phab ntsa, thiab lwm yam khoom siv hauv cov tshuaj nroj tsuag; Cov thermoplastics muaj peev xwm ua tiav los ntawm cov organic solvents, thiab cov thermosetting uas plastics siv. Ua tsis tau yaj, tsuas muaj qee yam ntawm qhov o tuaj xwb. Plastics kuj muaj kev tiv thaiv zoo rau ib puag ncig dej thiab muaj dej tsawg. Lawv tuaj yeem siv dav hauv cov dej tsis muaj dej thiab cov dej noo.
Qhov kub ntawm PE yeeb nkab tsis sib haum yog feem ntau tsis siab. Thaum twg thaum raug kub nyhiab, nws nyhav kom muag muag thiab deform, thiab txawm txhim kho thiab tsis zoo. Cov thermoplastics dog dig muaj kub kub kub ntawm 60-120 ° C, thiab tsuas yog ib qho me me ntawm ntau yam siv tau nyob ze li ntawm 200 ° C rau ib lub sij hawm ntev. . Qee cov khoom ua rau hluav taws lossis qeeb hlawv, thiab muaj cov pa phem ntau heev thaum tsim kev kub ntxhov, ua rau muaj kev kub ntxhov thaum muaj hluav taws hauv lub tsev. Qhov linear expansion coefficient ntawm plastics loj dua, 3-10 npaug loj dua hlau. Yog li ntawd, qhov kub siab deformation loj, thiab cov khoom siv tau yooj yim tawg vim lub txuam nrog thermal kev nyuab siab.
Vim nws tsis zoo thiab tsis txaus siab, nws tuaj yeem tiv thaiv kev puas tsuaj ntawm lub tsheb thiab cov khoom sib dhos, kev cia kom khov thiab yaj, thiab kev hloov hauv siab. Yog li, coils yuav siv tau rau kev siv los yog plowing kev tsim kho, uas yog qhov yooj yim rau kev tsim kho thiab tsim nqi tsawg dua engineering; Phab ntsa yog du, qhov nruab nrab ntwv tsis ua haujlwm me me, lub zog noj ntawm lub tsheb thauj mus los tsawg tsawg, thiab nws tsis raug rau cov tshuaj txhuam ntawm cov kua roj carbon dioxide nyob rau hauv lub tsheb thauj mus los. Nruab nrab thiab siab ceev PE kav dej yog tsim rau cov roj hauv cov pa roj thiab cov cua nkev. Cov PE kav yuav tsum siv rau hauv cov dej haus, cov kav dej thiab cov kev lag luam ntawm kev lag luam.
