Hom PE zaj duab xis

Tsawg ntom polyethylene
Nws qhov ceev yog li ntawm {{0}}.92g/cm3. Tsawg ntom ntom polyethylene zaj duab xis muaj cov pob tshab zoo thiab cov khoom cua sov sealing, thiab tuaj yeem ua dej tsis zoo thiab tsis muaj dej pov thawj; Tsawg tensile lub zog, siab tensile elongation, thiab yooj yim wrinkling. Rau cov yeeb yaj kiab hauv qab 0.03mm, kev tswj nruj yuav tsum yog me me, thiab qhov nro yuav tsum nyob txhua qhov chaw, tshwj xeeb tshaj yog thaum tshav kub kub, nws yog qhov yooj yim rau deformation, ua rau muaj teeb meem hauv kev sib txuam xim. 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 ua yeeb yaj kiab sib txawv, nws tuaj yeem muab faib ua ntau hom xws li zaj duab xis tshuab (IPE), zaj duab xis drooling (CPE), tsis tshua muaj foaming zaj duab xis, thiab lwm yam. Lub zog tensile thiab aperture ntawm IPE zaj duab xis yog zoo dua li ntawm CPE zaj duab xis. . Nws yog luam tawm rau pem hauv ntej thiab tuaj yeem siv los ua cov hnab ntim khoom noj, hnab khaub ncaws, thiab lwm yam; CPE zaj duab xis muaj cov tuab tuab, zoo dua qhov glossiness, pob tshab, thiab cov khoom cua sov sealing dua li PE, thiab tuaj yeem luam tawm ntawm ob sab, tab sis tus nqi ntau lawm 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, Pickled zaub thiab khoom qab zib; Low foaming zaj duab xis muaj cov khoom zoo nkauj, tuab zoo nkauj, thiab tsis yooj yim ncab lossis deformed. Nws yog luam tawm nyob rau hauv pem hauv ntej thiab siv raws li lub xyoo tshiab painting, trademark, thiab handbag.
Nruab nrab ntom polyethylene
Nws qhov ceev yog li ntawm 0.93-0.94g/cm3, thiab nws qhov kev ua tau zoo yog nruab nrab ntawm high-density thiab low-density polyethylene.
High ntom polyethylene
Qhov ceev yog nyob nruab nrab ntawm {{0}}.94-0.965g/cm3. High density polyethylene zaj duab xis muaj cov cua sov ua haujlwm zoo thiab lub zog ua haujlwm zoo dua li cov yeeb yaj kiab uas tsis tshua muaj polyethylene, nrog qis tensile elongation. Cov yeeb yaj kiab thickness feem ntau yog siab tshaj 0.03mm, tab sis cov pob tshab tsis zoo. Siv cov ntawv luam tawm pem hauv ntej, feem ntau yog siv rau lub hnab tsho khuam, hnab khib nyiab, thiab cov hnab hauv ob sab hauv.
Hla txuas polyethylene
Vim nws cov cua kub ntau dua, lub zog tensile, thermal shrinkage tus nqi, thiab cov khoom thaiv kev sib piv rau lwm cov khoom siv polyethylene, nws siv tau ntxiv. Nyob rau hauv 2014, nws yog feem ntau siv raws li ib tug thermal shrinkage ntim zaj duab xis.
Feem ntau hais lus, raws li qhov ceev nce, cov khoom siv kho tshuab thiab cov khoom thaiv yuav txhim kho, thiab cov cua sov kuj tseem yuav txhim kho. Polyethylene ntawm tib qhov ntom kuj muaj cov khoom sib txawv vim muaj cov txheej txheem ua yeeb yaj kiab sib txawv. Qhov no yog vim hais tias txoj kev salivation tuaj yeem txias sai, muaj crystallinity tsawg, siab transparency, thiab tsis tshua muaj turbidity, tab sis lub molecular kev npaj yog ntau irregular, uas ua rau qis barrier zog, transmittance ntau dua, qis elongation, thiab cov kua muag tsis zoo.
