Txheej txheem cej luam ntawm txoj kev loj hlob ntawm stretch zaj duab xis kev lag luam

Stretch zaj duab xis, tseem hu ua pallet ntim. Nws yog thawj zaug hauv Suav teb los tsim PVC stretch zaj duab xis nrog PVC ua cov khoom siv hauv paus thiab DOA ua cov yas yas thiab nws tus kheej nplaum ua haujlwm. Vim muaj teeb meem kev tiv thaiv ib puag ncig, tus nqi siab (xws li PE, qhov chaw ntim me me), tsis zoo stretchability thiab lwm yam laj thawj, PE stretch zaj duab xis tau maj mam tshem tawm thaum lub tsev tsim khoom ntawm PE stretch zaj duab xis tau pib xyoo 1994-1995. PE stretch zaj duab xis thawj zaug siv EVA ua cov khoom nplaum rau tus kheej, tab sis nws cov nqi yog siab thiab saj. Tom qab ntawd, PIB thiab VLDPE yog siv los ua cov khoom nplaum rau tus kheej. Cov khoom siv hauv paus yog tam sim no tsuas yog LLDPE, suav nrog C4, C6, C8 thiab metallocene PE. (MPE). Tam sim no sab qaum teb ntawm Tuam Tshoj yog sawv cev los ntawm "TOPEVER" stretch zaj duab xis tsim los ntawm Shandong Topever Group, uas tau yeej qhov kev nyiam ntawm cov neeg siv khoom los ntawm ntau lub teb chaws.

Thaum Ntxov LLDPE stretch zaj duab xis yog feem ntau tshuab zaj duab xis, los ntawm ib txheej mus rau ob-txheej thiab peb-txheej; tam sim no LLDPE stretch zaj duab xis yog tsuas yog tsim los ntawm txoj kev casting, vim hais tias cov casting kab ntau lawm muaj qhov zoo ntawm uniform thickness thiab siab transparency. Nws tuaj yeem siv rau cov kev xav tau ntawm qhov sib piv siab ua ntej ncab. Txij li ib txheej txheej casting tsis tuaj yeem ua tiav ib leeg ib sab, daim ntawv thov teb yog txwv. Ib txheej thiab ob txheej txheej casting tsis dav li peb-txheej casting nyob rau hauv cov nqe lus ntawm cov khoom xaiv, thiab formulation nqi kuj siab, yog li peb-txheej co-extrusion qauv yog zoo tagnrho. Cov yeeb yaj kiab zoo tshaj plaws yuav tsum muaj cov yam ntxwv ntawm cov pob tshab, siab ntev elongation, siab yield point, siab transverse tear zog, thiab kev ua haujlwm zoo.

Classification Ntawm Stretch Film

Tam sim no, stretch films ntawm kev ua lag luam tau muab faib ua ob hom: tes stretch films thiab tshuab stretch films raws li kev siv sib txawv. Lub thickness ntawm stretch zaj duab xis rau tes yog feem ntau 15μ-20μ, thiab lub thickness ntawm stretch zaj duab xis rau tshuab yog 20μ-30μ, tshwj tsis yog rau tshwj xeeb mob. Raws li cov txheej txheem ntim, stretch stretch film ntim tau muab faib ua phau ntawv stretch ntim, damping stretch ntim, thiab pre-stretch ntim. Muab faib los ntawm cov khoom siv, stretch zaj duab xis tuaj yeem muab faib ua polyethylene stretch zaj duab xis, polyvinyl chloride stretch film, ethylene-vinyl acetate stretch film, thiab lwm yam. Tam sim no, stretching films siv nyob rau hauv ntau lawm yog tag nrho raws li linear polyethylene, thiab polyethylene stretching films muaj. ua lub ntsiab ntawm stretching films. Raws li cov qauv ntawm cov yeeb yaj kiab, cov yeeb yaj kiab stretch tuaj yeem muab faib ua ib txheej ib txheej stretch zaj duab xis thiab ntau txheej stretch zaj duab xis. Feem ntau, tsuas yog ib sab yog nplaum, yog li nws feem ntau hu ua ib leeg-sab nplaum nplaum zaj duab xis. Nrog rau kev txhim kho cov cuab yeej tsim cov yeeb yaj kiab thiab thev naus laus zis, qhov zoo ntawm cov txheej txheem ntau txheej stretched zaj duab xis, uas yog qhov tsim nyog rau kev txhim kho cov khoom zoo thiab txo cov nqi khoom, tau dhau los ua qhov tseem ceeb. Tam sim no, stretched films nrog ib txheej txheej tau maj mam txo. Raws li kev sib txawv molding thiab kev ua, stretch zaj duab xis tuaj yeem muab faib ua zaj duab xis ncab thiab cam khwb cia stretch zaj duab xis, thiab cam khwb cia stretch zaj duab xis muaj kev ua tau zoo dua. Muab faib los ntawm daim ntawv thov, stretch zaj duab xis tuaj yeem muab faib ua zaj duab xis rau cov khoom ntim khoom lag luam (xws li zaj duab xis ncab rau ntim cov khoom siv hauv tsev, tshuab, tshuaj, khoom siv hauv tsev, thiab lwm yam), stretch zaj duab xis rau kev ntim khoom ua liaj ua teb, thiab ncab zaj duab xis rau tsev ntim khoom. .

Stretch Film Raw Khoom

Cov khoom siv tseem ceeb ntawm cov yeeb yaj kiab stretch yog LLDPE, thiab qib kev koom tes yog 7042. Vim qhov kev xav tau tshwj xeeb ntawm cov yeeb yaj kiab, 7042N, 1018HA, 1002YB, 218N thiab 3518CB kuj siv tau.

Stretch Zaj duab xis siv

Raws li ib feem tseem ceeb ntawm kev thauj khoom thauj, cov yeeb yaj kiab ncab plays lub luag haujlwm ntawm kev kho cov khoom. Nws yog dav siv nyob rau hauv papermaking, logistics, tshuaj lom neeg kev lag luam, yas raw cov ntaub ntawv, tsev cov ntaub ntawv, zaub mov, iav, thiab lwm yam .; nyob rau hauv kev lag luam tawm txawv teb chaws, papermaking, hardware, yas chemicals, tsev cov ntaub ntawv, Khoom noj khoom haus, tshuaj thiab lwm yam teb kuj koom nrog. Nws tuaj yeem hais tias qhov twg yog qhov chaw hloov chaw ntawm cov khoom, muaj lub xub ntiag ntawm peb cov yeeb yaj kiab stretch.

Stretch Film Production Equipment

Nyob rau hauv cov nqe lus ntawm machinery, tam sim no domestic stretch zaj duab xis ntau lawm khoom yog muab faib mus rau hauv txawv teb chaws kab thiab domestic ntau lawm kab. Cov kab ntau lawm yog los ntawm Ltalis, Tebchaws Meskas, thiab Lub Tebchaws Yelemees; Cov kab ntau lawm nyob rau hauv Jiangsu, Zhejiang, Hebei, thiab Guangdong. Thiab Changlongxing Machinery Manufacturing Factory yog cov paub zoo hauv Suav teb. Shandong Topever Group tam sim no tau tshaj tawm ntau cov kab ntau lawm los koom tes nrog ntau tshaj kaum cov kab tsim khoom hauv tsev rau kev xa tawm ntau lawm. Raws li ntau xyoo ntawm kev nkag siab txog kev lag luam, kev tsim khoom muaj peev xwm ntawm cov khoom siv sib txawv hauv ntau qhov chaw. Kev ceev ntawm cov khoom siv hauv tsev yog 80-150 m / min. Nyob rau hauv xyoo tas los no, cov cuab yeej siv high-speed ntawm 200-300 m / min yog nyob rau hauv kev tshawb fawb thiab kev loj hlob theem; thaum lub sij hawm ntau lawm ntawm cov kab txawv teb tau nce mus rau 300-400 m / min, 500 m / min Cov kab hluav taws xob ceev kuj tau tawm los. Stretch zaj duab xis casting ntau lawm cov khoom sib txawv ntawm tus nqi vim qhov sib txawv dav thiab ntau lawm ceev. Tam sim no, lub domestic 0.5m xov stretch zaj duab xis tshuab rau tes siv yog 70,000-80,000 / daim, thiab lub tshuab siv stretch zaj duab xis tshuab yog 90,000-100,000 / daim; 1-meter xov yog 200,000-250,000 / thooj; 2.0-meter kab yog nruab nrab ntawm 800,000 thiab 1.5 lab / thooj.
