Sikuti kuyesetsa peresenti malowedwe zana, monga zomera adzakhala kwambiri kukopedwa, kenako chipatso sadzakhala mmaso. Makumi asanu ndi atatu peresenti - izi ndi zokwanira kwa amadyera anali zimene ziyenera kukhalira. ukonde kachulukidwe akhoza zimasiyana magalamu 100 200 pa mita lalikulu. Thiabendazole angagwiritsidwe ntchito pa kutentha kuyambira +80 digiri -60. The elongation pa yopuma peresenti 250-500. Ziribe kanthu chomwe makulidwe, moyo umenewu filimu si oposa 1 nyengo. chiwerengerochi zosiyanasiyana mkati mamilimita 0,03 kwa 0.4. Izo zikhoza kugulidwa masikono ndi manja, amene ndi makulidwe osiyana, pomwe kutalika osachepera mamita 50.

polycarbonate ma

Kusankha zofunda zipangizo greenhouses, ogula zambiri kugula foni polycarbonate. Ichi ndi chifukwa durability mkulu. kamodzi kokha, alibenso nkhawa Zokonzazo zokwanira kumanga wowonjezera kutentha. Polycarbonate ali ndi makhalidwe chinanso kukaniza kutentha poyerekeza ndi galasi, imeneyi imagwira ntchito ngakhale ku makulidwe a 8 millimeters. Pa nthawi yomweyo amakhala nthawi 2 Zikanakhala bwino kusunga kutentha mkati kutentha lapansi. Pankhani makulidwe 16 millimeters, izo angayerekezedwe ndi atatu wosanjikiza glazing. Chifukwa kapangidwe ma amene ali kuumitsa, kutentha analandira osati wangwiro, komanso kutenthetsa. Opanga amanena kuti nkhani amatha kusunga yovuta cheza ultraviolet lomwe lili ndi zoyipa pa zomera.

Khalidwe pamwamba pa chuma yokutidwa ndi filimu zozitetezera.

Features wa ntchito polycarbonate

Kubisa mfundo greenhouses ntchito mu tandem ndi kachitidwe zotayidwa ogwiritsa, komanso mbiri ziwembu ena. Zofunika patsogolo unsembe kulabadira kwa koyefishienti cha kuwonjezedwa matenthedwe umene uli wofanana 0,068 millimeters 1 mita. chithunzi zingaoneke negligible, koma kutentha dontho la -20 kuti +30 polycarbonate kusintha kukula ndi 34 millimeters. Pamene ntchito kudziletsa pogogoda wononga kuti alibe kuwonjezeka ikukhudzana izo aswe pepala ndi kupanga dzenje chowulungika. Choncho tikulimbikitsidwa kuti ntchito washers chenicheni ndi m'mimba mwake wamkulu kuposa 30 millimeters. Woterowo fastener dzenje akhoza losindikizidwa. Kusankha ngati zakuthupi chophimba greenhouses, simungathe nkhawa mmene matalala. Pamwamba mwangwiro kupirira kumawononga makina. N'chifukwa chake wopanga amapereka chitsimikizo ntchito polycarbonate kwa zaka 10. Iwo akhoza anawerama, amene amasiyanitsa nkhani galasi, nchifukwa chake kwa icho imakonzedwa nyumba mosiyanasiyananso.

Nonwovens kwa greenhouses

The sanali nsalu chophimba mfundo greenhouses lerolino mwachilungamo ambiri. zipangizo zamakono za mtundu uwu mwangwiro kupirira kutentha posungira mu wowonjezera kutentha, ndiyeno kuupereka usiku. Komabe, chitetezo choterocho ndi kutentha si kupirira ndi chisanu ndi pa ntchito mwina kusiya. Iwo ayenera mwachilungamo mtengo zakuthupi. Masuku pamutu ndi mabvuto, monga mvula ndi kutseka padziko greenhouses Manga pulasitiki, ndipo kenako kuwombera. Kubisa zipangizo greenhouses Polycarbonate yayitali, koma ngati mukufuna kugwiritsa ntchito mfundo sanali nsalu, iwo adzakhala wokhoza kuteteza zomera ku frosts digiri -7. Adzaupulumutsa ndi matalala, dzuwa, mphepo yamphamvu ndi mvula.

Ntchito magalasi

Ngati mwasankha kufotokoza zipangizo kutentha, mukhoza kugula ndi galasi. Kapangidwe ndi ntchito ya cholimba, olimbika, ndi wochezeka. Kutentha adzatha kusunga chikhalidwe kuchokera frosts kwambiri. Ngati inu kugula galasi, kapangidwe akhoza ndalama mtengo ndithu, koma ngati muli ndi mwayi kugwiritsa ntchito zinthu anaitenga ku mafelemu akale a matabwa, ndi kutentha kuti mtengo kwambiri mwa onse.

Pomaliza
