pallet stretch zaj duab xis rau ntim

Stretch zaj duab xis, tseem hu ua stretch zaj duab xis thiab tshav kub shrink zaj duab xis, yog thawj nyob rau hauv Tuam Tshoj los tsim PVC stretch zaj duab xis nrog PVC raws li cov khoom siv hauv paus thiab DOA ua plasticizer thiab nws tus kheej-nplaum nyhuv. Vim muaj teeb meem kev tiv thaiv ib puag ncig, tus nqi siab (xws li PE lub siab feem ntau, tsawg dua chav ntim cheeb tsam), tsis muaj peev xwm ncab, thiab lwm yam, nws tau maj mam tshem tawm thaum lub tsev tsim khoom ntawm PE stretch zaj duab xis tau pib txij xyoo 1994 txog 1995. Lub PE stretch zaj duab xis thawj zaug siv EVA raws li tus kheej-nplaum khoom, tab sis nws cov nqi yog siab thiab nws muaj ib tug saj. Tom qab ntawd, PIB thiab VLDPE yog siv los ua cov khoom siv rau tus kheej, thiab cov khoom siv hauv paus yog LLDPE. Stretch zaj duab xis tuaj yeem muab faib ua: PE stretch zaj duab xis, PE stretch zaj duab xis, LLDPE stretch zaj duab xis, PE slit stretch zaj duab xis, thiab lwm yam. Nws tuaj yeem tsim cov yeeb yaj kiab ntau yam rau tes siv, hom kev siv tshuab siv, ua ntej-stretch hom tshuab siv, anti-ultraviolet, anti-static thiab anti-xeb. Nws muaj qhov zoo hauv qab no: Siv ob txheej txheej co-extrusion khoom, compressed stretch zaj duab xis tuaj yeem ua kom cov yam ntxwv ntawm txhua lub polymer, thiab nws cov pob tshab, lub zog tensile, thiab perforation kuj yog qhov zoo tshaj plaws thaum nws ncav cuag lub melting point. xwm txheej. 2. Nws muaj peev xwm stretch-zoo, zoo transparency thiab uniform thickness. 3. Nws muaj longitudinal extensibility, zoo resilience, zoo transverse tsim kua muag kuj, thiab zoo heev self-adhesive lap. 4. Nws yog ib puag ncig tus phooj ywg thiab cov khoom siv rov ua dua tshiab, saj tsis qab, tsis muaj tshuaj lom, thiab tuaj yeem ntim khoom noj ncaj qha. 5. Nws tuaj yeem tsim cov khoom ntim ib leeg, txo cov suab nrov tawm thaum lub caij winding thiab ncab, thiab txo cov plua plav thiab xuab zeb thaum thauj thiab khaws cia. 1. Cov ntim ntim ntim zoo li no zoo ib yam li ntim zaj duab xis. Zaj duab xis qhwv lub tais nyob ib ncig ntawm lub tais, thiab tom qab ntawd ob lub thermal grippers cua sov muab cov zaj duab xis ntawm ob qho kawg. Qhov no yog thawj zaug siv daim ntawv ntawm stretch zaj duab xis, thiab ntau cov ntaub ntawv ntim tau tsim los ntawm qhov no 2. Cov ntim ntim puv no yuav tsum muaj zaj duab xis dav txaus los npog lub pallet, thiab cov duab ntawm lub pallet yog li niaj zaus, yog li ntawd. nws muaj nws tus kheej, haum rau zaj duab xis thickness ntawm 17 ~ 35μm 3. Kev ceev ntim Cov ntim no yog qhov yooj yim tshaj plaws ntawm stretch film ntim. Cov zaj duab xis yog mounted rau ntawm ib lub khib los yog tes tuav, thiab lub tais tig los yog zaj duab xis tig ib ncig ntawm lub tais. Nws yog tsuas yog siv rau repackaging tom qab lub hnab ntim pallet puas lawm, thiab zoo tib yam pallet ntim. Hom kev ntim ceev no qeeb, thiab cov yeeb yaj kiab uas tsim nyog yog 15-20μm; 4. Stretch zaj duab xis wrapping tshuab ntim Qhov no yog cov feem ntau thiab dav daim ntawv ntawm txhua yam ntim. Lub tais tig los yog zaj duab xis tig ib ncig ntawm lub tais. Cov zaj duab xis yog tsau rau ntawm lub bracket thiab tuaj yeem txav mus los. Cov ntim ntim zoo li no yog qhov loj heev, txog 15-18 tais hauv ib teev. Qhov haum zaj duab xis thickness yog li 15-25μm; 5. Kab rov tav txhua yam ntim sib txawv ntawm lwm cov ntim khoom, cov yeeb yaj kiab revolves nyob ib ncig ntawm cov khoom, haum rau cov khoom ntim ntev, xws li cov ntaub pua plag, boards, fiberboards, cov ntaub ntawv zoo li tus, thiab lwm yam; 6. Kev ntim cov raj xa dej Qhov no yog ib qho ntawm cov khoom siv tshiab tshaj plaws ntawm cov yeeb yaj kiab ncab, uas yog qhov zoo dua li cov khoom qub ntawm cov ntawv raj ntim. Qhov haum zaj duab xis thickness yog 30 ~ 120μm; 7. Ntim ntawm cov khoom me me Qhov no yog daim ntawv ntim khoom tshiab ntawm stretch film, uas tuaj yeem tsis tsuas yog txo cov khoom siv, tab sis kuj txo qhov chaw cia ntawm pallets. Nyob rau hauv txawv teb chaws, hom ntim no yog thawj zaug hauv xyoo 1984. Tsuas yog ib xyoos tom qab, ntau lub ntim zoo li no tau tshwm sim hauv khw. Daim ntawv ntim no muaj peev xwm zoo heev. Haum rau zaj duab xis thickness ntawm 15 ~ 30μm; 8. Kev ntim cov raj thiab cables Qhov no yog ib qho piv txwv ntawm daim ntawv thov ntawm stretch zaj duab xis nyob rau hauv ib qho chaw tshwj xeeb. Cov khoom ntim khoom yog nruab rau ntawm qhov kawg ntawm cov kab ntau lawm. Lub siab tsis siv neeg stretch zaj duab xis tuaj yeem tsis tsuas yog hloov daim kab xev los khi cov khoom, tab sis kuj ua lub luag haujlwm tiv thaiv. Qhov siv tau thickness yog 15-30μm. 9. Stretching daim ntawv ntawm pallet mechanism ntim Lub ntim ntawm stretch zaj duab xis yuav tsum tau stretched. Cov ntaub ntawv stretching ntawm pallet mechanical ntim muaj xws li ncaj qha stretching thiab pre-stretching. Pre-stretching yog muab faib ua ob hom, ib qho yog yob pre-stretching thiab lwm yam yog hluav taws xob stretching. Direct stretching yog ua kom tiav qhov stretching ntawm lub tais thiab zaj duab xis. Qhov sib piv ntawm cov qauv no yog tsawg (li 15% -20%). Yog hais tias qhov sib piv stretching tshaj 55% ~ 60%, uas tshaj qhov qub yield point ntawm zaj duab xis, qhov dav ntawm zaj duab xis yog txo, thiab cov puncture kev ua tau zoo kuj poob. Yooj yim tawg. Thiab ntawm 60% ncab tus nqi, lub zog rub tseem loj heev, rau cov khoom siv lub teeb, nws yuav ua rau deform cov khoom.
