Kunezinhlobo eziningi zamafilimu okugcina ukushisa, futhi amafilimu ahlukene okugcina ukushisa anemisebenzi ehlukene. Ngaphezu kwalokho, ubukhulu befilimu yokugcina ukushisa bunobudlelwano obuhle nokukhula kwezitshalo. Ifilimu yokugcina ukushisa iwumkhiqizo wepulasitiki. Ehlobo, ifilimu yokugcina ukushisa ivezwa elangeni isikhathi eside, futhi kulula ukuguga futhi ibe buthaka, okuhlobene nobukhulu befilimu yokugcina ukushisa. Uma ifilimu yokugcina ukushisa ikhulu kakhulu, izobangela ukuguga, futhi uma ifilimu yokugcina ukushisa incane kakhulu, ngeke ikwazi ukudlala indima enhle ekulawuleni izinga lokushisa. Ngaphezu kwalokho, ubukhulu befilimu yokugcina ukushisa buhlobene nohlobo lwezitshalo, izimbali, njll. Sidinga ukukhetha amafilimu ahlukene okugcina ukushisa ngokwemikhuba yawo yokukhula.
Zingaki izinhlobo zamafilimu e-greenhouse? Amafilimu e-greenhouse avame ukuhlukaniswa abe yifilimu ye-PO greenhouse, ifilimu ye-PE greenhouse, ifilimu ye-EVA greenhouse, njalo njalo ngokwezinto ezibonakalayo.
Ifilimu ye-PO greenhouse: Ifilimu ye-PO ibhekisela kwifilimu yezolimo eyenziwe nge-polyolefin njengento eluhlaza eyinhloko. Inamandla aphezulu okudonsa, ukusebenza kahle kokuvikela ukushisa, futhi ingavikela kahle ukukhula kwezitshalo. Amandla okudonsa asho ukuthi ifilimu yezolimo idinga ukudonswa ngokuqinile lapho imbozwa. Uma amandla okudonsa engalungile, kulula ukudabuka, noma noma ingadabukanga ngaleso sikhathi, umoya onamandla ngezikhathi ezithile uzolimaza ifilimu yezolimo ye-PO. Ukuvikela ukushisa okuhle kuyisidingo esiyisisekelo kakhulu sezitshalo. Ukulawulwa kwezinga lokushisa nomswakama ngaphakathi kwefilimu yezolimo kuhlukile endaweni engaphandle kwefilimu ye-greenhouse. Ngakho-ke, ifilimu yezolimo ye-PO inomphumela omuhle wokulawula izinga lokushisa nomswakama, okusiza kakhulu ekukhuleni kwezitshalo futhi uthandwa kakhulu ngabantu.
Ifilimu ye-PE greenhouse: Ifilimu ye-PE uhlobo lwefilimu yezolimo ye-polyethylene, kanti i-PE isifinyezo se-polyethylene. I-Polyethylene uhlobo lwepulasitiki, kanti isikhwama sepulasitiki esisisebenzisayo uhlobo lomkhiqizo wepulasitiki we-PE. I-Polyethylene inokuqina okuhle kwamakhemikhali. I-Polyethylene kulula ukuyi-photo-oxidized, i-oxidized thermal, futhi i-ozone ibolile, futhi kulula ukuyibolisa ngaphansi kwesenzo semisebe ye-ultraviolet. I-carbon black inomphumela omuhle kakhulu wokuvikela ukukhanya ku-polyethylene.
Ifilimu ye-EVA greenhouse: Ifilimu ye-EVA ibhekisela kumkhiqizo wefilimu yezolimo one-ethylene-vinyl acetate copolymer njengento eyinhloko. Izici zefilimu yezolimo ye-EVA ukumelana kahle namanzi, ukumelana okuhle nokugqwala, kanye nokulondolozwa kokushisa okuphezulu.
Ukumelana namanzi: akumunci, akuvimbeli umswakama, futhi akuvumeli amanzi ukuthi angene kahle.
Ukumelana nokugqwala: ukumelana namanzi olwandle, uwoyela, i-asidi, i-alkali, kanye nokunye ukugqwala kwamakhemikhali, ukulwa namagciwane, okungenabo ubuthi, okungenambitheki, futhi okungenakungcola.
Ukushisa: ukushisa, ukushisa okuhle kakhulu, ukuvikelwa emakhazeni, kanye nokusebenza kahle kwezinga lokushisa eliphansi, futhi kungamelana nokubanda okukhulu kanye nokuchayeka elangeni.
Ungakhetha kanjani ubukhulu befilimu ye-greenhouse? Ubukhulu befilimu ye-greenhouse bunobudlelwano obuhle nokudluliselwa kokukhanya futhi bunobudlelwano obuhle nokuphila kwenkonzo okuphumelelayo.
Isikhathi sokusebenzisa esisebenzayo: Izinyanga eziyi-16-18, ubukhulu obungu-0.08-0.10 mm buyasebenziseka.
Isikhathi sokusebenzisa esisebenzayo: Izinyanga ezingama-24-60, ubukhulu obungu-0.12-0.15 mm buyasebenziseka.
Ubukhulu befilimu yezolimo esetshenziswa ezindaweni zokugcina izithombo ezinezikhawu eziningi kudinga ukuba ngaphezu kuka-0.15 mm.
