Kev faib tawm ntawm PE yas zaj duab xis

PE yas zaj duab xismuaj noo noo-pov thawj, noo noo permeability yog me me. PE Yas Zaj duab xis raws li cov txheej txheem kev tsim khoom sib txawv thiab kev tswj hwm txhais tau tias, tuaj yeem tsim qhov ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom polyethylene thiab crosslinked polyethylene thiab lwm yam khoom sib txawv ntawm cov khoom.
Tsawg ntom polyethylene
Nws qhov ceev yog li ntawm {{0}}.92 g/cm3. Tsawg ntom polyethylene zaj duab xis pob tshab thiab tshav kub sealing zoo, tsis muaj dej, tsis muaj dej pov thawj; Tsawg tensile lub zog, loj elongation, yooj yim rau wrinkle, 0.03mm hauv qab zaj duab xis, nruj tswj yuav tsum me me, thiab qhov nro yuav tsum tsis tu ncua, tshwj xeeb tshaj yog thaum tshav kub ntau deformation, ua rau xim nyuaj. Yog li ntawd, thaum ziab, qhov kub ntawm cov yeeb yaj kiab yuav tsum tsis txhob siab dhau (hauv 55 degrees). Raws li cov txheej txheem sib txawv ntawm zaj duab xis, nws tuaj yeem muab faib ua zaj duab xis yas (IPE), salivary zaj duab xis (CPE), zaj duab xis uas tsis tshua muaj foaming thiab lwm yam. Lub zog tensile thiab qhib ntawm IPE zaj duab xis yog zoo dua li ntawm CPE zaj duab xis, uas tuaj yeem siv los ua lub hnab ntim khoom noj, hnab khaub ncaws thiab lwm yam. CPE zaj duab xis tuab yog zoo ib yam, nto gloss, pob tshab thiab kub sealing zoo dua PE, tuaj yeem luam tawm ntawm ob sab, tab sis tus nqi tsim khoom yog siab. CPE zaj duab xis yog tsuas yog siv los ua txheej txheej hauv cov hnab ntim khoom thiab ntim cov tshuaj pleev ib ce, pickles thiab pastries; Tsawg foaming zaj duab xis zoo nkauj, tuab kev ntxhib los mos, tsis yooj yim rau stretch deformation, zoo luam ntawv, siv raws li cov duab Xyoo Tshiab, cov cim lag luam thiab cov hnab.
Nruab nrab ntom polyethylene
Nws qhov ceev yog li ntawm {{0}}.93 ~ 0.94 g / cm3 thiab nws cov khoom nyob nruab nrab ntawm qhov ntom ntom ntom ntom ntom ntom ntom ntom polyethylene.
High ntom polyethylene
Qhov ceev yog {{0}} 94 -- 0.965 g/cm3. Lub tshav kub tsis kam thiab cov neeg kho tshuab lub zog ntawm high density polyethylene zaj duab xis yog zoo dua li ntawm tsawg ntom polyethylene zaj duab xis, thiab elongation yog me me. Lub thickness ntawm zaj duab xis yog feem ntau siab tshaj 0.03mm, tab sis lub pob tshab tsis zoo. Txais kev luam ntawv pem hauv ntej, feem ntau yog siv los ua lub hnab tsho khuam, hnab khib nyiab thiab lub hnab hauv ob sab phlu.
Crosslinked polyethylene
Vim tias nws muaj kev kub ntxhov siab dua, lub zog tensile, thermal shrinkage thiab barrier dua li lwm yam khoom siv polyethylene, nws siv nyob rau hauv kev nthuav dav ntxiv, 2014 feem ntau yog siv rau cov khoom siv thermal shrinkage.
Feem ntau hais lus, nrog qhov nce ntawm qhov ntom ntom, cov khoom siv kho tshuab thiab cov khoom thaiv kev tiv thaiv yuav raug txhim kho, kev ua haujlwm kub yog qhov zoo. Tib qhov ntom ntom polyethylene, vim yog cov txheej txheem sib txawv ntawm cov yeeb yaj kiab, lawv kuj muaj cov khoom sib txawv. Qhov no yog vim txoj kev salivation tuaj yeem txias sai sai, crystallinity tsawg, pob tshab yog siab, turbidity yog me me, tab sis cov txheej txheem molecular tsis sib xws, yog li qhov teeb meem me me, uas yog, qhov permeability loj, elongation tsawg, lub kua muag kuj tsis zoo.
