Ichando chiripo munyika kana mumunda unobvumira muridzi kuti atore kare kare kupfuura kubva pamibhedha iri pasi. Mukuwedzera kune chiremera chechigadziro chinogona kuonekwa uye nguva yakakura yezvibereko. Ndicho chikonzero varimi vazhinji vanofunga kuti vakura miriwo nemiriwo mumagetsi . Vakawanda vanowana gadziriro yakagadzirwa yakagadzirwa nemari yakawanda, nenzira. Asi iwe unogona kuita gorofu nemaoko ako, ayo, ayo, zvechokwadi, achaderedza zvakanyanya kuparadza zvinhu. Uye nenzira, chimwe chezvinhu zvinokosha ndeyekupfeka. Kazhinji kazhinji muhutano huno, iyo firimu inoshandiswa - izvo zvinhu zvisingadhuri uye zviri nyore, uye mune dzimwe nguva zvinogara zvakasimba. Kana uri kufunga nezvekuvhara greenhouse frame nekufunga pamusoro payo, tichakutaurira kuti firipi iri nani kune yakasvibira uye iyo inofanira kusarudza.
Firimu yezvivigiro - sei ungasarudza?
Kuti hupenyu hwako husingaperi huvepo huzadzise mabasa ayo, firimu inofanira kunge iine zvinhu zvinotevera:
- mvura isina mvura;
- zvakajeka;
- elastic;
- kusagadzikana nekupisa;
- kufema;
- chiedza chinopararira.
Pasina mubvunzo, nekuda kweizvi firimu yakasimba ye polyethylene yakakodzera, iyo inonyanya kukosha. Asi inogonawo kuva yemhando dzakasiyana, imwe neimwe ine maitiro ayo, sezvichakurukurwa pasi apa.
Mhando yefirimu ye polyethylene yezvivigiro
Pamarudzi ose emafirimu anotengeswa pamusika, chaizvoizvo akasimba, zvitatu chete:
- reinforced;
- kwenguva refu;
- polyvinyl chloride.
Mafirimu anosimbiswa pamagadziro ezvinyorwa zvakanyanya kwazvo ane huni hwemukati hwemukati hwomukati (s) ye polypropylene kana fiberglass. Firimu yakadaro, kunyange yakasimba (kushumira makore 2-3), asi ine zvishoma zvakakwana.
Purogiramu yepa polyethylene yefirimu yezvivigiro uye maturaji ndiyo inonyanya kusarudzwa pamusika. Inoshandisa mashoko akadaro haasisina nguva imwe chete, asi inozivikanwa nevagari vezhizha nokuda kwehupfumi hwayo.
Polyvinyl chloride film , zvinoratidzirwa kurangarira cellophane, inoonekwa seimwe yezvinhu zvakasimba zvakanyanya. Nyaya dzakadaro dzine chiedza chikuru chekuenderera kwemaitiro - kwete pasi pe 90%. Mukuwedzera, iyo polyvinyl chloride film inokwanisa kuchengetedza zvinopfuura 90% ye infrared uye inopfuura 80% yemirairo ye ultraviolet. Iri kupfeka rakakodzera mumamiriro ezvinhu apo pane chinangwa chokudzivirira pakupisa kwe greenhouse.
Iko kusingaperi kwemafuro emapurisa mapepa ibhuku guru rezvinhu zvokuputira magirasi emhando dzakasiyana-siyana, dzakawanda dzazvo dzakaitwa ye polyethylene nezvidimbu zvakasiyana-siyana kugadzirisa nzvimbo. Semuenzaniso, chiedza chakasimudzirwa mafirimu emagasiro akasiyana-siyana kubva pane zvinowanzoitika pakugadzirwa kwayo kunosanganisira zvinhu zvakasiyana. Kuvonga ichi chiwedzerero, izvo zvinhu zvinonzi UV zvinogadzikana uye saka zvinoparadzwa zvishoma nezvishoma nemhaka yezuva. Ma subspecies ayo, mafirimu madema nechena machena , akavezwa kune rumwe rutivi mumuchena, kune rimwe - mune rima. Nokuda kweizvi, rutivi rusiya runotora kupisa kwezuva, uye ruvara rutsvuku, pane zvinopesana, runoratidzika. Ichokwadi, mashoko akadaro anoshandiswa sekuputika kwepamusoro pevhu muchitema
Yakasimbiswa hydrophilic firimu inokubvumira kubvisa chiitiko ichocho, chimiro chezvivigiro, sezvinoitwa mangwanani mangwanani mukati memukati mukati mehutu. Izvozvo zvinokonzera madonhwe emvura zvinongopfuurira pasi pefirimu. Muchikamu chemakore akawanda anonyanya kushandiswa, iyo kuwedzera kunodzivirira kuonekwa kweguruva pamusoro pevhu. Kutora-kuchengetedza firimu kunotonhora kupisa nekuda kwekuti nokuti nekuda kwehutano hahupfuuri mahara emhepo. Air-bubble film for greenhouses is a three-layer structure: the inner layer of air bubbles is surrounded by 2 sides by a smooth film. Izvo zvakagadziriswa mvura inogadzikana uye kusanaya kwechando.
