Kunezinhlobo eziningi zamafilimu abamba ukushisa, futhi amafilimu ahlukahlukene abamba ukushisa anemisebenzi ehlukene.Ngaphezu kwalokho, ukushuba kwefilimu ye-greenhouse kunobudlelwano obukhulu nokukhula kwezitshalo.Ifilimu ye-greenhouse ingumkhiqizo wepulasitiki.Ehlobo, ifilimu ye-greenhouse ivezwa elangeni isikhathi eside, futhi kulula ukuguga futhi ibe brittle, nayo ehlobene nobukhulu befilimu ye-greenhouse.Uma ifilimu ye-greenhouse iminyene kakhulu, izodala into yokuguga, futhi uma ifilimu ye-greenhouse incane kakhulu, ngeke ikwazi ukudlala indima enhle ekulawuleni izinga lokushisa.Ngaphezu kwalokho, ukushuba kwefilimu ye-greenhouse nakho kuhlobene nohlobo lwezitshalo, izimbali, njll. Kudingeka sikhethe amafilimu abamba ukushisa ahlukene ngokwemikhuba yawo yokukhula.
Zingaki izinhlobo zamafilimu abamba ukushisa?Amafilimu abamba ukushisa avame ukuhlukaniswa abe yifilimu ye-PO greenhouse, ifilimu ye-PE greenhouse, ifilimu ye-EVA greenhouse, njalonjalo ngokusho kwempahla.
Ifilimu ye-PO greenhouse: Ifilimu ye-PO ibhekisela kwifilimu yezolimo eyenziwe nge-polyolefin njengento eyinhloko eluhlaza.Inamandla aphezulu okuqina, ukusebenza kahle kwe-thermal insulation, futhi ingakuvikela kahle ukukhula kwezitshalo.Amandla okuqina asho ukuthi ifilimu yezolimo idinga ukudonswa ngokuqinile lapho imboza.Uma amandla okuqina engalungile, kulula ukudatshulwa, noma ngisho noma engadabukile ngaleso sikhathi, umoya onamandla ngezikhathi ezithile uzodala umonakalo kwifilimu yezolimo ye-PO.Ukufakwa kahle kwezinga lokushisa kuyisidingo esiyisisekelo sezitshalo.Ukulawula izinga lokushisa nomswakama ngaphakathi kwefilimu yezolimo kuhlukile endaweni engaphandle kwefilimu ye-greenhouse.Ngakho-ke, ifilimu yezolimo ye-PO inomphumela omuhle wokulawula izinga lokushisa nomswakama, osiza kakhulu ekukhuleni kwezitshalo futhi ethandwa kakhulu ngabantu.
Ifilimu ye-PE greenhouse: Ifilimu ye-PE iwuhlobo lwefilimu yezolimo ye-polyethylene, kanti i-PE isifinyezo se-polyethylene.I-polyethylene iwuhlobo lwepulasitiki, futhi isikhwama sepulasitiki esisisebenzisayo siwuhlobo lomkhiqizo wepulasitiki we-PE.I-polyethylene inokuqina okuhle kwamakhemikhali.I-Polyethylene kulula uku-photo-oxidized, i-oxidized thermally, futhi i-ozone ibole, futhi kulula ukuwohloka ngaphansi kwesenzo semisebe ye-ultraviolet.I-Carbon black inomphumela omuhle kakhulu wokuvikela ukukhanya ku-polyethylene.
Ifilimu ye-EVA greenhouse: Ifilimu ye-EVA ibhekisa kumkhiqizo wefilimu wezolimo one-ethylene-vinyl acetate copolymer njengento esemqoka.Izici zefilimu yezolimo ye-EVA ukumelana kahle kwamanzi, ukumelana nokugqwala okuhle, nokugcinwa kokushisa okuphezulu.
Ukumelana namanzi: ukungamunceli, umswakama-ubufakazi, ukumelana kahle kwamanzi.
Ukumelana nokugqwala: imelana namanzi olwandle, uwoyela, i-asidi, i-alkali, nokunye ukugqwala kwamakhemikhali, i-antibacterial, non-toxic, ayinambitheki, futhi ayinakungcola.
Ukufakwa kwe-thermal: ukufakwa kokushisa, ukufakwa kwe-thermal okuhle kakhulu, ukuvikeleka okubandayo, nokusebenza okunezinga lokushisa eliphansi, futhi kungamelana nokubanda okukhulu nokuchayeka elangeni.
Ungakhetha kanjani ubukhulu befilimu ye-greenhouse?Ugqinsi lwefilimu ye-greenhouse inobudlelwano obuhle nokudluliswa kokukhanya futhi inobudlelwano obuhle nempilo yesevisi esebenzayo.
Isikhathi sokusebenzisa esisebenzayo: izinyanga eziyi-16-18, ukushuba kwe-0.08-0.10 mm kuyasebenziseka.
Isikhathi sokusebenzisa esisebenzayo: izinyanga ezingama-24-60, ukushuba kwe-0.12-0.15 mm kuyasebenziseka.
Ubukhulu befilimu yezolimo esetshenziswa ezindlini zokugcina izithombo ezine-span multi-span kufanele bube ngaphezu kuka-0.15 mm.
