Hariho ubwoko bwinshi bwa firime ya parike, na firime zitandukanye za parike zifite imirimo itandukanye. Byongeye kandi, ubunini bwa firime ya parike ifite isano ikomeye no gukura kwibihingwa. Filime ya greenhouse nigicuruzwa cya plastiki. Mu mpeshyi, firime ya parike ihura nizuba igihe kirekire, kandi biroroshye gusaza no gucika intege, ibyo bikaba bifitanye isano nubunini bwa firime ya parike. Niba firime ya greenhouse ari ndende cyane, bizatera ibintu byo gusaza, kandi niba firime ya parike ari nto cyane, ntishobora kugira uruhare runini mukugenzura ubushyuhe. Byongeye kandi, ubunini bwa firime ya parike nayo ifitanye isano nubwoko bwibihingwa, indabyo, nibindi. Tugomba guhitamo firime zitandukanye za parike dukurikije ingeso zabo zo gukura.
Ubwoko bwa firime zingahe? Filime ya Greenhouse isanzwe igabanyijemo firime ya PO greenhouse, PE greenhouse film, EVA greenhouse film, nibindi ukurikije ibikoresho.
PO greenhouse firime: Filime ya PO yerekeza kuri firime yubuhinzi ikozwe muri polyolefine nkibikoresho nyamukuru. Ifite imbaraga nyinshi, imikorere myiza yubushyuhe bwumuriro, kandi irashobora kurinda neza imikurire y ibihingwa. Imbaraga zingana bivuze ko firime yubuhinzi igomba gukururwa cyane mugihe itwikiriye. Niba imbaraga zidasanzwe atari nziza, biroroshye gushwanyagurika, cyangwa niyo bitaba byacitse muri kiriya gihe, umuyaga ukaze rimwe na rimwe uzangiza ibyangiritse muri firime yubuhinzi PO. Gukwirakwiza amashyuza meza nicyo kintu cyibanze gisabwa kubihingwa. Kugenzura ubushyuhe nubushuhe imbere muri firime yubuhinzi bitandukanye nibidukikije hanze ya firime ya parike. Kubwibyo, PO yubuhinzi bwa PO ifite ubushyuhe bwiza nubushuhe bwo kurwanya ubushuhe, bufasha cyane mukuzamura ibihingwa kandi bikundwa nabantu.
PE greenhouse film: PE film ni ubwoko bwa firime yubuhinzi ya polyethylene, naho PE ni impfunyapfunyo ya polyethylene. Polyethylene ni ubwoko bwa plastiki, kandi umufuka wa pulasitike dukoresha ni ubwoko bwibicuruzwa bya plastiki PE. Polyethylene ifite imiti ihamye. Polyethylene iroroshye kuba ifoto-oxyde, okiside yumuriro, na ozone ibora, kandi biroroshye kwangirika bitewe nimirasire ya ultraviolet. Umukara wa karubone ufite ingaruka nziza zo gukingira polyethylene.
Filime ya parike ya EVA: Filime ya EVA ivuga ibicuruzwa bya firime yubuhinzi hamwe na Ethylene-vinyl acetate copolymer nkibikoresho byingenzi. Ibiranga firime yubuhinzi ya EVA ni ukurwanya amazi meza, kurwanya ruswa, no kubika ubushyuhe bwinshi.
Kurwanya amazi: kudakurura, kutagira amazi, kurwanya amazi meza.
Kurwanya ruswa: irwanya amazi yo mu nyanja, amavuta, aside, alkali, nizindi miti yangirika, antibacterial, idafite uburozi, uburyohe, kandi nta mwanda.
Ubushyuhe bwumuriro: kubika ubushyuhe, kubika neza ubushyuhe, kurinda ubukonje, no gukora ubushyuhe buke, kandi birashobora kwihanganira ubukonje bukabije nizuba.
Nigute ushobora guhitamo ubunini bwa firime ya parike? Umubyimba wa firime ya parike ufite umubano mwiza nogukwirakwiza urumuri kandi ufite umubano mwiza nubuzima bwiza bwa serivisi.
Igihe cyo gukoresha neza: amezi 16-18, umubyimba wa 0.08-0.10 mm urashobora gukora.
Igihe cyo gukoresha neza: amezi 24-60, umubyimba wa 0.12-0.15 mm urashobora gukora.
Umubyimba wa firime yubuhinzi ukoreshwa muri parike nyinshi zigomba kuba zirenga mm 0,15.
