Mfundo yopewera miliri idasinthidwa ndipo PVC idakulitsidwanso

Pa Juni 28, mfundo zopewera ndi kuwongolera miliri zidatsika, kukayikira pamsika sabata yatha kunakula kwambiri, msika wazinthu zambiri udakweranso, ndipo mitengo m'malo onse mdziko muno idakwera.Ndi kubwezeredwa kwamtengo, phindu lamtengo wapatali linachepa pang'onopang'ono, ndipo zambiri zomwe zimachitika ndizochitika zaposachedwa.Malo ena ochitirako zinthu anali abwinoko kuposa dzulo, koma kunali kovuta kugulitsa katundu pamtengo wokwera, ndipo ntchito yonseyo inali yathyathyathya.
Ponena za zofunikira, kuwongolera kumbali yofunikira ndikofooka.Pakalipano, nyengo yapamwamba yadutsa ndipo pali dera lalikulu la mvula, ndipo kukwaniritsidwa kofunikira sikuli kocheperapo kusiyana ndi kuyembekezera.Makamaka pakumvetsetsa kwa mbali yoperekera, zowerengera zimasonkhanitsidwa nthawi zambiri motsutsana ndi nyengo, zomwe zikupitilirabe kukakamiza mitengo.Zomwe zili ndi ziyembekezo zamphamvu ndi zenizeni zofooka zimafunikirabe nthawi yokonzanso.
Panthawi imodzimodziyo, mtengo wamafuta osakanizidwa unagwa kwambiri, ndipo mtengo wa calcium carbide unapitirira kutsika, ndipo malire a PVC mtengo wothandizira mbali anafooka.Komabe, pakadali pano, mabizinesi omwe amagwiritsa ntchito njira yakunja yamigodi ya calcium carbide amawonongeka.Pansi pa PVC kuyang'anitsitsa ndi phindu, ngati makampani akupitirizabe kutayika, katundu woyambira akhoza kuletsedwa, ndipo kuyambika kwa PVC palokha kukugweranso pamtunda wapamwamba woyendetsedwa ndi kukonza, ndipo msika udzakhalabe. landirani chithandizo kuchokera ku mbali yopereka chithandizo pakanthawi kochepa.Kuonjezera apo, vuto la mphamvu za kunja kwa nyanja likupitirirabe.Pakadali pano, China ikulowa m'chilimwe.Ndikufika pachimake chogwiritsa ntchito mphamvu, pali mphekesera za kugawidwa kwa mphamvu kumapeto kwa Ulanqab.Pankhani ya kutayika kwa mabizinesi a calcium carbide, zoyambira za calcium carbide yaiwisi zimatha kusintha.
