I-PE Tarpaulin: Izinto ezikhuselayo ezisetyenziswa ngeendlela ezininzi

I-PE tarpaulin, isishunqulelo se-polyethylene tarpaulin, ngelaphu elikhuselayo elisetyenziswa kakhulu elenziwe nge-polyethylene (PE) resin, i-polymer eqhelekileyo ye-thermoplastic. Ukuthandwa kwayo kuvela kumxube weempawu ezisebenzayo, ukusebenza kakuhle kweendleko, kunye nokuguquguquka, okwenza ukuba ibe yinto ebalulekileyo kwiimeko zoshishino nezemihla ngemihla.

Ngokuphathelele ukwakheka kwezinto, i-PE tarpaulin isebenzisa ikakhulu i-polyethylene enoxinano oluphezulu (HDPE) okanye i-polyethylene enoxinano oluphantsi (LDPE). Ezo zisekelwe kwi-HDPE zinika amandla aphezulu okuxinana kunye nokuqina, ngelixa iintlobo ze-LDPE ziguquguquka ngakumbi. Izinto ezongezelelweyo ezifana neziqinisi ze-UV (ukuxhathisa umonakalo welanga), ii-arhente zokulwa nokwaluphala (ukwandisa ubomi), kunye nezilungisi zokuthintela amanzi zihlala zongezwa. Ezinye iintlobo ezinzima zikwanayo ne-polyester elukiweyo okanye i-nylon mesh reinforcement ukuze zikwazi ukumelana nokukrazuka ngcono.

Inkqubo yokuvelisa ibandakanya amanyathelo amathathu abalulekileyo. Okokuqala, i-PE resin kunye nezongezo ziyaxutywa, zinyibilikiswe kwi-160-200℃，kwaye zikhutshwe kwiifilimu okanye kwiishiti. Emva koko, iinguqulelo ezikhaphukhaphu ziyasikwa emva kokuba zipholile, ngelixa ezo zinzima zigqunywa nge-PE kwisiseko esilukiweyo. Okokugqibela, ukutywinwa komphetho, ukubhoboza ii-eyelet, kunye nokuhlolwa komgangatho kuqinisekisa ukusetyenziswa kakuhle. I-PE tarpaulin ineempawu ezintle kakhulu. Ayinamanzi ngokwemvelo, ithintela imvula kunye nombethe ngokufanelekileyo. Nge-UV stabilizers, inyamezela ukukhanya kwelanga ngaphandle kokuphela okanye ukuqhekeka. Ilula (80-300g/㎡) kwaye iguquguquka, kulula ukuyiphatha nokuyisonga, ifaka izinto ezingacwangciswanga kakuhle. Ikwafikeleleka kwaye amabala ayo angalungiswa kakhulu angacocwa ngamanzi okanye isepha ethambileyo.

Izicelo eziqhelekileyo ziquka ukugubungela imithwalo kwimpahla yokuthutha impahla, ukusebenza njengezigqubuthelo zegreenhouse okanye ingca kwezolimo, ukusebenza njengophahla lwexeshana ekwakheni, kunye nokusetyenziswa njengeentente zokukhempisha okanye izigqubuthelo zeemoto kwimisebenzi yemihla ngemihla yangaphandle. Nangona inemida efana nokumelana nobushushu obuphantsi kunye nokumelana nokukrala okungekuhle kwiintlobo ezincinci, i-PE tarpaulin iseyeyona ndlela ifanelekileyo yokukhusela ngokuthembekileyo.
