Kodi pali kusiyana kotani pakati pa ma insulation osiyanasiyana a chingwe cha polyethylene

Masiku omwe mawaya opanda mkuwa anali ovomerezeka apita. Ngakhale mawaya amkuwa ndi othandiza kwambiri, amafunikabe kutetezedwa kuti apitirize kugwira ntchito bwino mosasamala kanthu za momwe amagwiritsidwira ntchito. Ganizirani za kutetezedwa kwa waya ndi chingwe ngati denga la nyumba yanu, ndipo ngakhale sizingawoneke ngati zambiri, zimateteza zinthu zonse zamtengo wapatali mkati, choncho ndi nthawi yoti mudziwe kusiyana pakati pa mawaya osiyanasiyana oteteza. Ndikofunikira kudziwa zipangizo zomwe zimagwiritsidwa ntchito mu mtundu uliwonse wa kutetezera ndi ntchito zomwe zikuyenera kugwiritsidwa ntchito.

Polyethylene yolemera kwambiri ya mamolekyulu, ndiye chotchingira waya cha thermoplastic chomwe chimagwiritsidwa ntchito kwambiri poteteza anode. Chabwino kwambiri, chotchingira cha mamolekyulu cholemera kwambiri ndi choyenera kugwiritsidwa ntchito mwachindunji poika maliro. Chifukwa cha kuchuluka kwa mamolekyulu, chotchingira cha chingwechi chimatha kupirira kuphwanyika, kusweka, kusokonekera, ndi zina zotero chifukwa cha kulemera kwakukulu ndi kukakamizidwa. Chophimba cha polyethylene chimapereka mphamvu ndi kusinthasintha, zomwe zikutanthauza kuti chotchingiracho chingathe kuzunzidwa kwambiri popanda kuwononga chingwe chenicheni. Chogwiritsidwa ntchito kwambiri pa mapaipi, matanki osungira, zingwe zam'madzi, ndi zina zotero…

Chotchingira cha polyethylene cholumikizidwa ndi mtanda ndi chimodzi mwazosankha zosinthika kwambiri pamsika. Chotchingira cha XLPE chimalimbana ndi mankhwala ambiri omwe amagwiritsidwa ntchito mumakampani opanga zingwe, chimagwira ntchito kutentha kwambiri komanso kotsika, sichimalowa madzi, ndipo chimalola zingwe zamkati kutumiza ndikulandira magetsi ambiri. Zotsatira zake, zotchingira monga XLPE ndizodziwika bwino mumakampani opangira kutentha ndi kuziziritsa, mapaipi amadzi ndi machitidwe, komanso kugwiritsa ntchito kulikonse komwe kumafuna makina amphamvu kwambiri. Zabwino kwambiri zotchingira za XLPE ndizotsika mtengo poyerekeza ndi zotchingira zambiri za waya ndi zingwe.

Kuteteza kwa polyethylene yochuluka kwambiri kumanena kuti ndi njira yolimba kwambiri komanso yamphamvu kwambiri yotetezera mawaya. Kuteteza kwa HDPE sikusinthasintha ngati kutetezera kwina, koma sizikutanthauza kuti sikungakhale kothandiza ngati kuyikidwa pamalo oyenera. Ndipotu, kukhazikitsa mawaya, ma conduit, ndi ntchito zina zambiri zimafuna kutetezera kosasinthasintha. Kuteteza kwamphamvu kwambiri sikuwononga ndipo sikuteteza UV kwambiri, zomwe zikutanthauza kuti ndi koyenera kugwiritsidwa ntchito panja.

Pitirizani kulabadira chingwe cha Jiapu, kuti mudziwe zambiri zokhudza makampani opanga chingwe. Chingwe cha Jiapu ndi inu mupita patsogolo motsatizana.
