Kukho iintlobo ngeentlobo zeefilimu zegreenhouse, kwaye iifilimu ezahlukeneyo zegreenhouse zinemisebenzi eyahlukeneyo. Ukongeza, ubukhulu befilimu yegreenhouse bunobudlelwane obuhle nokukhula kwezityalo. Ifilimu yegreenhouse yimveliso yeplastiki. Ehlotyeni, ifilimu yegreenhouse ivezwa elangeni ixesha elide, kwaye kulula ukuyiguga ize ibe buthathaka, nto leyo enxulumene nobukhulu befilimu yegreenhouse. Ukuba ifilimu yegreenhouse ityebile kakhulu, iya kubangela ukuguga, kwaye ukuba ifilimu yegreenhouse ityebile kakhulu, ayizukukwazi ukudlala indima entle ekulawuleni ubushushu. Ngaphezu koko, ubukhulu befilimu yegreenhouse bukwanxulumene nohlobo lwezityalo, iintyatyambo, njl. Kufuneka sikhethe iifilimu zegreenhouse ezahlukeneyo ngokwemikhwa yazo yokukhula.
Zingaphi iintlobo zeefilimu zegreenhouse? Iifilimu zegreenhouse zihlala zahlulwe zibe yifilimu ye-PO greenhouse, ifilimu ye-PE greenhouse, ifilimu ye-EVA greenhouse, njalo njalo ngokwezinto ezisetyenzisiweyo.
Ifilimu ye-PO greenhouse: Ifilimu ye-PO ibhekisa kwifilimu yezolimo eyenziwe nge-polyolefin njengeyona nto iphambili. Inamandla aphezulu okutsalwa, ukusebenza kakuhle kokugquma ubushushu, kwaye inokukhusela kakuhle ukukhula kwezityalo. Amandla okutsalwa athetha ukuba ifilimu yezolimo kufuneka itsalwe ngokuqinileyo xa igqunywa. Ukuba amandla okutsalwa akalungile, kulula ukukrazulwa, okanye nokuba ayikrazulwanga ngelo xesha, umoya onamandla ngamanye amaxesha uya kubangela umonakalo kwifilimu yezolimo ye-PO. Ukugquma ubushushu obuhle yeyona mfuneko iphambili kwizityalo. Ulawulo lobushushu kunye nokufuma ngaphakathi kwifilimu yezolimo lwahlukile kwindawo engaphandle kwefilimu ye-greenhouse. Ke ngoko, ifilimu yezolimo ye-PO inempembelelo elungileyo yokulawula ubushushu kunye nokufuma, enceda 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 oluhle kakhulu lweekhemikhali. I-Polyethylene kulula ukuyi-photo-oxidized, i-oxidized thermal, kwaye i-ozone ibolile, kwaye kulula ukuyibolisa phantsi kwesenzo semitha ye-ultraviolet. I-carbon black inefuthe elihle kakhulu lokukhusela ukukhanya kwi-polyethylene.
Ifilimu ye-EVA greenhouse: Ifilimu ye-EVA ibhekisa kwimveliso yefilimu yezolimo ene-ethylene-vinyl acetate copolymer njengesixhobo esiphambili. Iimpawu zefilimu yezolimo ye-EVA kukumelana kakuhle namanzi, ukumelana kakuhle nokugqwala, kunye nokugcinwa kobushushu obuphezulu.
Ukumelana namanzi: ayifunxi, ayinyangeki kufuma, ayinyangeki kakuhle ngamanzi.
Ukumelana nokugqwala: ukumelana namanzi olwandle, ioyile, iasidi, ialkali, kunye nezinye iikhemikhali zokugqwala, ukulwa neentsholongwane, ukungatyi tyhefu, ukunganambitheki, kunye nokungangcolisi.
Ubushushu obuphezulu: Ubushushu obuphezulu, ubushushu obuphezulu obuphezulu, ukhuseleko oluphezulu, kunye nokusebenza kakuhle kobushushu obuphantsi, kwaye inokumelana nokubanda okukhulu kunye nokukhanya kwelanga.
Ungayikhetha njani ubukhulu befilimu yegreenhouse? Ubukhulu befilimu yegreenhouse bunobudlelwane obuhle nokuhanjiswa kokukhanya kwaye bunobudlelwane obuhle nobomi benkonzo esebenzayo.
Ixesha lokusetyenziswa ngokufanelekileyo: Iinyanga ezili-16-18, ubukhulu obuyi-0.08-0.10 mm buyasebenziseka.
Ixesha lokusetyenziswa ngokufanelekileyo: Iinyanga ezingama-24-60, ubukhulu obuyi-0.12-0.15 mm buyasebenziseka.
Ubukhulu befilimu yezolimo esetyenziswa kwiindawo zokugcina izityalo ezininzi kufuneka bube ngaphezu kwe-0.15 mm.
