Ubwino wa kugwiritsa ntchito CPE mu zingwe

Ponena za mawaya ndi zingwe zotsika mphamvu, zimagawidwa m'magulu awiri malinga ndi cholinga chawo: mawaya omangira ndi mawaya amagetsi. Mu waya womangira, unali waya wachilengedwe wotetezedwa ndi labala wolukidwa ndi phula kuyambira m'ma 1960. Kuyambira m'ma 1970, wasinthidwa kwathunthu ndi mawaya apulasitiki a PVC. Mkhalidwe wa mizere ya zida zamagetsi ndi wofanana ndi wa mizere yomangira, yomwe poyamba inkalamulidwa ndi rabala yachilengedwe, koma idasinthidwa kwambiri ndi zingwe za PVC m'ma 1970. Mkhalidwewu ndi wosamveka komanso wosamveka pankhani ya makampani a zingwe ndi zosankha za ogwiritsa ntchito. Masiku ano, zingwe zosiyanasiyana zamagetsi, makamaka zingwe zolumikizira zomwe zimafunikira pazida zapakhomo zomwe zikukula, ziyenera kusintha momwe zinthu zilili pano polamulidwa ndi pulasitiki ya PVC ndikuzisintha ndi zingwe za rabala. Chifukwa zingwe za rabala zili ndi zabwino zapadera monga kufewa, kumva bwino m'manja, kusaopa kutentha, komanso kusasungunuka, sizingafanane ndi zingwe zapulasitiki. Chifukwa cha zabwino zake zambiri zomwe rabala yopangidwa ilibe, CPE ingagwiritsidwe ntchito kwambiri popanga zingwe zamagetsi zapakhomo ndi zingwe zina zosinthika zamagetsi. CPE ili ndi zinthu zambiri zaukadaulo, monga kuchedwa kwa moto bwino komanso kukana mafuta kwambiri, zinthu zakuthupi ndi zamakaniko (monga zinthu zamakaniko), kukana kutentha kwambiri, kukana ozoni, kukana nyengo, zinthu zamagetsi zabwino, komanso kugwira ntchito bwino. Itha kugwiritsidwa ntchito pazida zogwiritsira ntchito rabara, ndipo zinthu za rabara sizimayaka kwambiri. Zipangizo zopangira za CPE sizimawonongeka pakatha zaka zingapo zosungidwa, Zipangizo za rabara zokhala ndi zinthu zowononga zimatha kusungidwa kwa zaka 1-2 popanda kuwonongeka pansi pa malo abwino osungira.

Mwachidule, kugwiritsa ntchito CPE mumakampani opanga zingwe pa intaneti, ndiko kuti, kusintha CR ndi CPE, ndi chizolowezi mumakampani opanga zingwe pa intaneti. Izi sizimangochepetsa kutsutsana kwa CR pakufunikira kwa zinthu, komanso zimachepetsa kwambiri mtengo wa zinthu zopangira zingwe, zimawonjezera phindu lazachuma lamakampani opanga zingwe, komanso zimakhala ndi tanthauzo lalikulu pakukweza mtundu wa zinthu zopangira zingwe ndikupangitsa mitundu yosiyanasiyana ya zingwe kukhala yosiyana.
