Polyethylene (PE) muaj lub cev zoo, tshuaj lom neeg thiab cov khoom siv dag zog, zoo toughness, yooj yooj yim thiab cushioning zog, hluav taws xob rwb, hluav taws kub rwb thaiv tsev thiab lwm yam ntxwv, dav siv rau hauv ntim, tshuaj lom neeg thiab kev lag luam. PE foaming khoom yog ib qho khoom siv ntau tshaj plaws siv foaming.
Cov ntaub ntawv PE ntau yuav muab faib ua ntau hom kev sib txuas, muaj qes thiab cov khoom siv microporous ntau raws li tus npoo ntau, cov ntaub qhwv, daim ntawv thiab cov ntaub qhwv ntsej muag cov ntaub ntawv raws li cov duab, thiab kaw thiab qhib cov khoom siv foaming raws li tus qauv ntawm lub npuas. Tam sim no, cov khoom siv ntawm PE foaming cov khoom tsuas yog tsis zoo rau polyurethane (PU) thiab polystyrene (PS), tab sis nws yog siv ntau dua PU thiab PS. Ntau tshaj 1000 hom khoom tsim tau tsim, thiab txoj kev loj hlob yog sai, thiab nws muaj lub siab xav coj tus kab mob yav tom ntej.
Kev loj hlob ntawm 1 PE npuas cov ntaub ntawv
Tsoom fwv Patent siv PE ntau tshaj plaws * tau tsim los ntawm DuPont Company nyob rau xyoo 1941. Lub patent siv nitrogen ua tus neeg ua kab npuas ncauj kom ua npuas nyob ze ntawm lub pob zeb ntawm PE, tab sis vim tias nws tsis tuaj yeem ua haujlwm tsis tu ncua, nws tsis tau siv ntau hauv kev lag luam. Nyob rau hauv 1958, Dow tau pom tau hais tias yog kev lag luam industrialized ntawm PE cov ntaub ntawv siab nrog tetrafluorodichloroethane ua tus neeg ua hauj lwm ntau tshaj plaws uas tsis yog crosslinking extrusion foaming thawj zaug. Tam sim no, feem ntau ntawm cov ntaub ntawv kawm PE ntau hauv Tebchaws Meskas tseem tsim tawm los ntawm qhov qauv no.
Nyob rau xyoo 1960, Nyiv Sanhe Chemical Co., Ltd., Guhe Electric Co., Ltd. thiab Waterlogged Chemistry Co., Ltd. tau tsim thiab tsim kev sib txuas ntawm high-foaming PE cov khoom, thiab pib tsim high-foaming PE cov khoom hauv 1965 Qhov no tsuas yog siv tus neeg saib xyuas kev sib txuas lus los txhim kho lub zog ntawm PE yaj thiab cov khoom ntim ntau.
Cov teb chaws Europe pib tsim tau crosslinked PE ntau xyoo nyob rau xyoo 1970s. Tam sim no, feem ntau cov tuam txhab tsim cov khoom PE foamed raws li tshuab tsim hauv Nyiv. Txawm li cas los xij, cov khoom siv tom qab ntoo khaub lig tsis tuaj yeem siv tsis tu ncua, thiab yog ib qho yooj yim kom ua rau muaj kev ua pa tsis zoo. PE foamed ntawv tau txais los ntawm kev siv foaming lub cev feem ntau hu ua pearl paj rwb hauv Suav teb. Nws muaj cov kab uas tsis yog crosslinking kaw-cell qauv thiab yog ib yam tshiab ntawm ib puag ncig tiv thaiv ntim khoom. Nws yog tsim ntawm ntau ntau npuas yeem tsim los ntawm lub cev ua npuas ncauj ntawm cov neeg tsawg PE. Nws overcomes lub shortcomings ntawm ntau foamed plastics xws li fragility, deformation thiab ploj rov qab, thiab muaj kev sib cais. Cov dej ua pov thawj, kev pov thawj, kev tiv thaiv kev tiv thaiv, kev txuag hluav taws xob, kev ruaj ntseg zoo, kev muaj zog, kev tiv thaiv ib puag ncig, kev sib tsoo thiab kev ua haujlwm zoo.
Txij li thaum kawg ntawm lub xyoo pua 20, yuav kom daws tau qhov kev thov rau cov khoom tsim tshwj xeeb zoo li ntau cov khoom siv, Japanese JSP thiab Kaneka tuam txhab tau tsim cov khoom sib txuas ntawm PE foamed hlaws (EPE), los ntawm lub tshuab molding yuav ua tau tau ntsib nrog cov kev cai ntawm ntau yam qauv thiab cov khoom ntawm EPE ua npuas ncauj. Lub reactor impregnation method yog dav siv nyob rau hauv cov EPE ntau lawm. Txawm li cas los xij, autoclave foaming txheej txheem yog complex thiab tus nqi ntawm cov khoom siv siab. Tam sim no, tsuas yog ib lub tuam txhab tsawg, xws li JSP Corporation ntawm Nyiv, Kaneka Company, BASF Company ntawm lub teb chaws Yelemees, Kauslim Teb, Kauslim Teb, Kauslim Teb, Kauslim, thiab Kauslim, tau siv lub tshuab.
