Kukho iintlobo ezininzi zeefilimu ze-greenhouse, kunye neefilimu ze-greenhouse ezahlukeneyo zinemisebenzi eyahlukeneyo.Ukongezelela, ubukhulu befilimu ye-greenhouse inobudlelwane obukhulu kunye nokukhula kwezityalo.Ifilimu ye-greenhouse yimveliso yeplastiki.Ehlotyeni, ifilimu ye-greenhouse ibonakaliswe elangeni ixesha elide, kwaye kulula ukuguga kwaye ibe yi-brittle, ehambelana nobukhulu befilimu ye-greenhouse.Ukuba ifilimu ye-greenhouse inzima kakhulu, iya kubangela ukuguga, kwaye ukuba ifilimu ye-greenhouse incinci kakhulu, ayiyi kukwazi ukudlala indima efanelekileyo ekulawuleni ukushisa.Ngaphezu koko, ubukhulu befilimu ye-greenhouse ihambelana nohlobo lwezityalo, iintyatyambo, njl. Kufuneka sikhethe iifilimu ezahlukeneyo ze-greenhouse ngokwemikhwa yazo yokukhula.
Zingaphi iintlobo zeefilimu ze-greenhouse?Iifilimu ze-Greenhouse zihlala zihlulwe kwifilimu ye-PO greenhouse, ifilimu ye-PE greenhouse, ifilimu ye-EVA greenhouse, njalo njalo ngokwezinto eziphathekayo.
Ifilimu ye-PO greenhouse: Ifilimu ye-PO ibhekisa kwifilimu yezolimo eyenziwe ngepololefin njengeyona nto iphambili ekrwada.Inamandla aphezulu okuzibamba, ukusebenza kakuhle kokugquma kwe-thermal, kwaye inokukhusela kakuhle ukukhula kwezityalo.Amandla okuqina kuthetha ukuba ifilimu yezolimo kufuneka itsalwe ngokuqinileyo xa igqunywa.Ukuba amandla okuqina awalungile, kulula ukukrazulwa, okanye nokuba ayikrazulwanga ngelo xesha, umoya onamandla ngamaxesha athile uya kubangela umonakalo kwifilimu yezolimo yePO.Ukugqunywa kakuhle kwe-thermal yeyona mfuneko isisiseko kwizityalo.Ulawulo lobushushu kunye nokufuma ngaphakathi kwefilimu yezolimo yahlukile kwindawo engaphandle kwefilimu yegreenhouse.Ngoko ke, ifilimu yezolimo ye-PO inefuthe elihle lokulawula ukushisa kunye nomswakama, oluncedo kakhulu ekukhuleni kwezityalo kwaye ithandwa kakhulu ngabantu.
Ifilimu ye-PE greenhouse: Ifilimu ye-PE luhlobo lwefilimu yezolimo ye-polyethylene, kwaye i-PE sisifinyezo se-polyethylene.I-Polyethylene luhlobo lweplastiki, kwaye ingxowa yeplastiki esiyisebenzisayo luhlobo lwemveliso yeplastiki ye-PE.I-polyethylene inozinzo olugqwesileyo lweekhemikhali.I-Polyethylene kulula ukuba i-photo-oxidized, i-oxidized thermally, kunye ne-ozone ibolile, kwaye kulula ukuthotywa phantsi kwesenzo semitha ye-ultraviolet.Ikhabhoni emnyama inefuthe elihle kakhulu lokukhusela ukukhanya kwi-polyethylene.
Ifilimu ye-EVA greenhouse: Ifilimu ye-EVA ibhekisela kwimveliso yefilimu yezolimo ene-ethylene-vinyl acetate copolymer njengento ephambili.Iimpawu zefilimu yezolimo ye-EVA kukuxhathisa okulungileyo kwamanzi, ukuxhathisa okulungileyo kwe-corrosion, kunye nokugcinwa kobushushu obuphezulu.
Ukuchasana namanzi: ukunganyangeki, ubungqina bokufuma, ukuxhathisa okulungileyo kwamanzi.
Ukumelana ne-Corrosion: ukumelana namanzi olwandle, i-oyile, iasidi, ialkali, kunye nokunye ukubola kweekhemikhali, antibacterial, non-toxic, tasteless, and pollution-free.
Ukufakwa kwe-thermal: ukugqunywa kobushushu, ukugqunywa kwe-thermal okugqwesileyo, ukhuseleko olubandayo, kunye nokusebenza okuphantsi kobushushu, kwaye inokumelana nengqele eqhaqhazelisa amazinyo kunye nokuba sesichengeni selanga.
Indlela yokukhetha ubukhulu befilimu ye-greenhouse?Ubukhulu befilimu ye-greenhouse inobudlelwane obukhulu kunye nokuhanjiswa kokukhanya kwaye inobudlelwane obukhulu kunye nobomi benkonzo obusebenzayo.
Ixesha elisebenzayo lokusetyenziswa: iinyanga ezili-16-18, ubukhulu be-0.08-0.10 mm busebenza.
Ixesha elisebenzayo lokusetyenziswa: iinyanga ezingama-24-60, ubukhulu be-0.12-0.15 mm busebenza.
Ubukhulu befilimu yezolimo esetyenziswe kwii-greenhouses ezininzi kufuneka zibe ngaphezu kwe-0.15 mm.
