Kunezinhlobo eziningi zamafilimu abamba ukushisa, namafilimu ahlukene abamba ukushisa anemisebenzi ehlukile. Ngaphezu kwalokho, ubukhulu be-greenhouse film bunobudlelwano obuhle nokukhula kwezilimo. Ifilimu eliluhlaza lingumkhiqizo wepulasitiki. Ehlobo, ifilimu eliluhlaza livezwa ilanga isikhathi eside, futhi kulula ukuya eminyakeni yobudala futhi libe yi-brittle, elihlobene nobukhulu befilimu yokumba ukushisa. Uma ifilimu eliluhlaza likhulu kakhulu, lizodala into egugile, futhi uma ifilimu eliluhlaza lincane kakhulu, ngeke likwazi ukudlala iqhaza elihle ekulawulweni kokushisa. Ngaphezu kwalokho, ukushuba kwefilimu eliluhlaza kuhlobene nohlobo lwezitshalo, izimbali, njll. Sidinga ukukhetha amafilimu ahlukene abamba ukushisa ngokuya ngemikhuba yabo yokukhula.
Zingaki izinhlobo zamafilimu abamba ukushisa? Amafilimu abamba ukushisa ahlukaniswe nge-po greenhouse film film, pe greenhouse film, eva greenhouse film, nokunye okunjalo ngokwezinto ezibonakalayo.
Ifilimu yokubulala abamba ukushisa Inamandla aphezulu ashubile, ukusebenza okuhle kokufakwa okushisayo, futhi kungavikela kahle ukukhula kwezilimo. Amandla asheshayo asho ukuthi ifilimu yezolimo idinga ukudonswa ngokuqinile lapho isembozo. Uma amandla ashukumisayo alungile, kulula ukuklebhuka, noma noma kungakadwengu ngaleso sikhathi, umoya onamandla wesikhashana uzodala ukulimala kwefilimu yezolimo yePo. Ukufakelwa okuhle okushisayo kuyimfuneko eyisisekelo kunazo zonke yezilimo. Ukulawulwa kokushisa kanye nomswakama ngaphakathi kwefilimu yezolimo kwehlukile emvelweni ngaphandle kwefilimu eliluhlaza okotshani. Ngakho-ke, ifilimu yezolimo ye-PO inokushisa okuhle nokulawulwa komswakama, okusiza kakhulu ukukhula kwezilimo futhi kuthandwa kakhulu ngabantu.
Ifilimu ye-Greenhouse ye-PE: Ifilimu ye-PE uhlobo lwefilimu yezolimo ye-polyethylene, ne-PE yisifinyezo se-polyethylene. I-Polyethylene uhlobo lwepulasitiki, futhi isikhwama sepulasitiki esisisebenzisayo uhlobo lomkhiqizo wepulasitiki we-PE. I-PolyethLene inokuqina okuhle kwamakhemikhali. I-PolyethYlene kulula ukuyisebenzisa nge-oxidised, i-oxidised enenhlonipho, futhi i-ozone ibolile, futhi kulula ukwehla ngaphansi kwesenzo se-ultraviolet ray. I-Carbon Black inomphumela omuhle kakhulu wokuvikelwa ukukhanya ku-polyethylene.
Ifilimu ye-Eva Greenhouse: Ifilimu ye-Eva isho umkhiqizo wefilimu yezolimo nge-ethylene-vinyl acetate copolymer njengezinto eziphambili. Izici zefilimu yezolimo ye-Eva zingukumelana kwamanzi okuhle, ukumelana kahle nokugqwala, kanye nokulondolozwa okuphezulu okuphezulu.
Ukumelana Amanzi: Okungamukeli, umswakama-ubufakazi, ukumelana kwamanzi okuhle.
Ukuphikiswa kokugqwala: Ukumelana namanzi olwandle, uwoyela, acid, alkali, kanye nokunye ukugqwala kwamakhemikhali, ama-antibacterial, angenabuthi, anambitheki.
Ukufakwa kwe-Thermal: Ukufakwa kokushisa, ukufakwa okuhle kakhulu okushisayo, ukuvikelwa okubandayo, nokusebenza okushisa okuphansi, futhi kungabekezelela ukuvezwa okunzima nokulangazelela kwelanga.
Ungakukhetha kanjani ubukhulu befilimu yokumba ukushisa? Ubukhulu be-greenhouse film bunobuhlobo obuhle nokudluliselwa kokukhanya futhi kunobudlelwano obuhle nempilo yenkonzo esebenzayo.
Isikhathi sokusebenzisa esisebenzayo: Izinyanga eziyi-16-18, ubukhulu be-0.08-0.10 mm busebenza.
Isikhathi sokusebenzisa esisebenzayo: izinyanga ezingama-24-60, ubukhulu be-0.12-0.15 mm asebenza.
Ubukhulu befilimu yezolimo esetshenziswa ezindaweni zokugcina izithombo ezinama-span budinga ukwedlula i-0.15 mm.
