Kune marudzi akawanda emafirimu egreenhouse, uye mafirimu egreenhouse akasiyana ane mabasa akasiyana.Mukuwedzera, kukora kwefirimu yegreenhouse kune hukama hukuru nekukura kwezvirimwa.Iyo firimu yegreenhouse chigadzirwa chepurasitiki.Muzhizha, firimu yegreenhouse inoratidzwa kune zuva kwenguva yakareba, uye zviri nyore kukwegura uye kuva brittle, iyo inobatanidzawo nehupamhi hwefirimu yegreenhouse.Kana iyo firimu yegreenhouse yakanyanyisa, inokonzera chiitiko chekukwegura, uye kana firimu yegreenhouse yakanyanya kuonda, haizokwanisi kuita basa rakanaka mukutonga kwekushisa.Uyezve, kukora kwefirimu yegreenhouse kunobatanidzawo nemhando yezvirimwa, maruva, nezvimwewo. Tinofanira kusarudza mafirimu akasiyana-siyana ekupisa maererano nemaitiro avo ekukura.
Ndeapi marudzi emafirimu egreenhouse?Mafirimu eGreenhouse anowanzo kukamurwa kuita PO greenhouse firimu, PE greenhouse film, EVA greenhouse film, zvichingodaro zvinoenderana nezviri.
PO greenhouse firimu: PO firimu inoreva firimu rekurima rakagadzirwa nepololefin seyakanyanya mbishi zvinhu.Iyo ine yakakwira tensile simba, yakanaka yekupisa insulation performance, uye inogona kunyatso chengetedza kukura kwezvirimwa.Kusimba kwesimba zvinoreva kuti firimu rekurima rinoda kudhonzwa zvakasimba kana richivhara.Kana simba rekusimba risina kunaka, zviri nyore kubvamburwa, kana kuti kana risina kubvaruka panguva iyoyo, dzimwe nguva mhepo ine simba inokonzera kukanganisa kwePO yekurima firimu.Kuchengetedzwa kwemafuta kwakanaka ndicho chinonyanya kudiwa pazvirimwa.Iyo tembiricha uye humidity control mukati mefirimu rekurima rakasiyana kubva kune zvakatipoteredza kunze kweiyo greenhouse film.Naizvozvo, PO firimu rekurima rine tembiricha yakanaka uye humidity control effect, iyo inobatsira zvikuru mukukura kwezvirimwa uye inodiwa zvikuru nevanhu.
PE greenhouse film: PE firimu imhando yepolyethylene yekurima firimu, uye PE ndiyo chidimbu chepolyethylene.Polyethylene imhando yepurasitiki, uye bhegi repurasitiki ratinoshandisa imhando yePE plastiki chigadzirwa.Polyethylene ine yakanakisa kugadzikana kwemakemikari.Polyethylene iri nyore kuve mafoto-oxidized, thermally oxidized, uye ozone yakaora, uye zviri nyore kudzikisira pasi pekuita kwe ultraviolet rays.Carbon dema ine yakanakisa mwenje-kudzivirira maitiro pa polyethylene.
EVA greenhouse firimu: EVA firimu rinoreva zvekurima firimu chigadzirwa chine ethylene-vinyl acetate copolymer sechinhu chikuru.Hunhu hweEVA firimu rekurima kwakanaka kwemvura inodzivirira, yakanaka corrosion resistance, uye yakanyanya kupisa kuchengetedza.
Kupokana kwemvura: kusatora, kunyorova-uchapupu, kunaka kwemvura.
Corrosion resistance: inoshingirira kumvura yegungwa, oiri, asidhi, alkali, uye kumwe kusvibiswa kwemakemikari, antibacterial, non-chepfu, isina kunaka, uye isina kusvibiswa.
Thermal insulation: kupisa kupisa, yakanakisa kupisa kwemafuta, kudzivirira kutonhora, uye kuderera-kupisa kuita, uye inogona kumira kutonhora kwakanyanya uye kuratidzwa nezuva.
Nzira yekusarudza sei kukora kwefirimu yegreenhouse?Ukobvu hwefirimu yegreenhouse ine hukama hukuru nemwenje transmittance uye zvakare ine hukama hukuru nehupenyu hwesevhisi hunoshanda.
Inoshanda nguva yekushandisa: 16-18 mwedzi, ukobvu hwe0.08-0.10 mm hunoshanda.
Inoshanda nguva yekushandisa: 24-60 mwedzi, ukobvu hwe0.12-0.15 mm hunoshanda.
Ukobvu hwefirimu rekurima rinoshandiswa mune dzakawanda-span greenhouses dzinoda kudarika 0.15 mm.
