BOPE yog lub npe luv ntawm Biaxially Oriented Polyethylene, uas yog, biaxially taw qhia polyethylene zaj duab xis. Nws yog tsim los ntawm tshwj xeeb LLDPE thiab HDPE raw cov ntaub ntawv, uas yog stretched longitudinally thiab ces transversely. Piv nrog rau ntau lawm los ntawm tshuab moulding (IPE) los yog casting method (CPE) polyethylene zaj duab xis.
Muaj kev txhim kho tseem ceeb hauv lub cev. BOPE zaj duab xis muaj cov pob tshab siab, muaj zog txhua yam muaj zog thiab ib qho yooj yim tearing.
Piv nrog rau cov yeeb yaj kiab PE ib txwm muaj, qhov kev tiv thaiv kev sib tsoo yog txhim kho, tshwj xeeb tshaj yog nyob rau hauv daim ntawv thov ntawm cov khoom ntim khoom ntim qis. Hais txog kev ua tau zoo, nws tuaj yeem txo tus nqi ntawm pob tawg thaum lub sijhawm thauj mus los thiab tso saib.
Nyob rau tib lub sijhawm, cov khoom lag luam muaj cov thickness zoo sib xws, kev ua haujlwm kub sealing, zoo noo noo tsis kam, zoo longitudinal thiab transverse tensile zog, thiab muaj qhov zoo ntawm noo noo tsis kam thiab foldability.
Biaxially oriented polyethylene zaj duab xis (bope zaj duab xis) yog ua tiav thiab tsim los ntawm cov txheej txheem ca zaj duab xis biaxial stretching, nrog loj stretching piv thiab ntau lawm efficiency. Cov yeeb yaj kiab muaj lub zog zoo heev, cov khoom siv kho qhov muag, kev sib khi kub, dej tsis kam, dej tsis kam thiab breathability Nws yog cov khoom ntim zoo tshaj plaws thiab tau siv dav hauv ntim khoom noj, txiv hmab txiv ntoo thiab zaub, khoom siv me nyuam, thiab lwm yam. txoj haujlwm tseem ceeb hauv kev ua lag luam.
Nws qhov zoo yog raws li nram no:
1. Hloov tshuab los yog cam khwb cia CPE zaj duab xis nrog ib nrab tuab BOPE thiab qhuav compounding nrog BOPA lossis BOPET tuaj yeem ua tiav tib lub zog sealing thiab zoo sib xws.
2. Siv ib nrab-thickness BOPE es tsis txhob tshuab moulding los yog cam khwb cia CPE zaj duab xis thiab BOPA qhuav compounding rau khov ntim ntawm -18 degree tuaj yeem txo lub hnab tawg zoo heev.
Nws daim ntawv thov yog: es tsis txhob tshuab molding thiab casting PE zaj duab xis thiab BOPA los yog BOPET thiab txhuas ntawv ci qhuav los yog extrusion compound hnab ua, los yog ib txheej fusion sealing hnab ua, los yog txheej, los yog compound PE zaj duab xis, thiab lwm yam., siv rau ntau yam ntim. rau khoom noj lossis khoom siv txhua hnub, thiab lwm yam.
