Pakalipano, China ikupita ku cholinga cha carbon peak ndi carbon neutralization, kuthetsa mpweya woipa wa carbon dioxide kupyolera mwa kusunga mphamvu ndi kuchepetsa mpweya.Poyankha ku chitukuko cha zomanga za dziko lobiriwira ndi cholinga cha carbon peak, makampani a miyala amayesetsa kutenga mwayi ndikupereka zopereka zoyenera ku carbon peak ndi carbon neutralization pogwiritsa ntchito luso lamakono ndi luso lazogulitsa.
Monga gawo lochotsa mwala wachilengedwe, mwala wochita kupanga umapangitsa kuti miyala yachilengedwe ikhale yabwino komanso imachepetsa kupsinjika kwa chilengedwe.Ubwino wogwiritsa ntchito zinthu zonse kumapangitsa kuti miyala yopangidwa ndi anthu ikhale ndi gawo lofunikira pakuteteza chilengedwe komanso kupulumutsa mphamvu.Ndi zomangira zobiriwira zobiriwira komanso zida zatsopano zoteteza chilengedwe.
Malingana ndi chidziwitso cha anthu, kupanga ndi kupanga miyala yopangira miyala sikusowa kuwombera kutentha kwambiri.Poyerekeza ndi zida za ceramic, simenti ndi magalasi, mphamvu yogwiritsira ntchito mphamvu pakupanga ndi yochepa kwambiri, yomwe imachepetsa kwambiri mphamvu yogwiritsira ntchito mphamvu pamtengo wamtengo wapatali ndipo imathandizira kusunga mphamvu ndi kuchepetsa umuna;Komanso, mphamvu zomwe zimagwiritsidwa ntchito popanga ndi kukonza ndi mphamvu yamagetsi.Ngakhale kuti mbali ya mphamvu yamagetsi imachokera ku mphamvu yamagetsi yamagetsi pakalipano, mphamvu yamagetsi yamtsogolo ikhoza kubwera kuchokera ku mphamvu ya mphepo, mphamvu ya photovoltaic mphamvu, mphamvu ya nyukiliya, etc. Choncho, mwala wopangidwa ndi anthu ukhoza kupangidwa kwathunthu ndi mphamvu zoyera m'tsogolomu.
Kuphatikiza apo, utomoni womwe uli mumiyala yokumba ndi 6% mpaka 15%.Unsaturated polyester resin yomwe imagwiritsidwa ntchito pakali pano makamaka imachokera ku mafuta oyenga mafuta, omwe ali ofanana ndi kutulutsa mwachinyengo "carbon" yokwiriridwa m'chilengedwe, kuonjezera mphamvu ya mpweya wa carbon;M'tsogolomu, kakulidwe ka miyala yopangira R & D idzatenga pang'onopang'ono utomoni wachilengedwe, ndipo mpweya wa zomera umachokera ku carbon dioxide mumlengalenga.Chifukwa chake, utomoni wachilengedwe ulibe mpweya watsopano.
Mwala wokongoletsera womanga ukhoza kugawidwa mumwala wachilengedwe ndi miyala yopangidwa ndi anthu.Ndi kukweza kwa kadyedwe komanso kukwera kwa lingaliro lomanga zokongoletsera zabwino, miyala yopangidwa ndi anthu yokhala ndi maubwino angapo ikulandila chidwi chachikulu kuchokera kwa anthu.Pakalipano, mwala wochita kupanga umagwiritsidwa ntchito kwambiri m'munda wa zokongoletsera zamkati ndi ma countertops monga khitchini, bafa ndi malo odyera.

Deta ya kafukufuku wamabizinesi ikuwonetsa kuti pakadali pano, pali mabizinesi okhudzana ndi 9483 "mwala wopangira" omwe adalembetsedwa ku China, omwe 7145 alipo komanso m'makampani.Kuyambira 2011 mpaka 2019, kulembetsa mabizinesi oyenerera kunawonetsa kukwera.Mwa iwo, mabizinesi okhudzana ndi 1897 adalembetsedwa mu 2019, kufikira opitilira 1000 kwa nthawi yoyamba, ndikuwonjezeka kwa chaka ndi 93.4%.Guangdong, Fujian ndi Shandong ndi zigawo zitatu zomwe zili ndi mabizinesi ambiri okhudzana.64% yamabizinesi ali ndi ndalama zolembetsedwa zosakwana 5 miliyoni.
Mu theka loyamba la 2021, mabizinesi okhudzana ndi 278 adalembetsedwa mdziko lonse, kutsika kwachaka ndi 70.6%.Voliyumu yolembetsa kuyambira Januware mpaka Juni idatsika kwambiri poyerekeza ndi nthawi yomweyi chaka chatha, pomwe voliyumu yolembetsa kuyambira Epulo mpaka Juni inali yosakwana gawo limodzi mwa magawo atatu a chaka chatha.Malinga ndi izi, voliyumu yolembetsa ikhoza kutsika kwambiri kwa zaka ziwiri zotsatizana.
▲ mu 2020, mabizinesi okhudzana ndi miyala 1508 adalembetsedwa, ndi kuchepa kwa chaka ndi 20.5%
Deta ya kafukufuku wamabizinesi ikuwonetsa kuti Chigawo cha Guangdong chili ndi mabizinesi ambiri okhudzana ndi "miyala yopangira", omwe ali ndi 2577, komanso ndi chigawo chokhacho chomwe chili ndi katundu wopitilira 2000. Chigawo cha Fujian ndi Chigawo cha Shandong chidakhala chachiwiri ndi chachitatu 1092 ndi 661 motsatana.
▲ zigawo zitatu zapamwamba ku Guangdong, Fujian ndi Shandong
Zambiri za kafukufuku wamabizinesi zikuwonetsa kuti 27% yamabizinesi ali ndi capital capital yochepera 1 miliyoni, 37% ali ndi likulu lolembetsedwa pakati pa 1 miliyoni ndi 5 miliyoni, ndipo 32% ali ndi likulu lolembetsedwa la 5 miliyoni mpaka 50 miliyoni.Kuphatikiza apo, 4% yamabizinesi ali ndi capital capital yoposa 50 miliyoni.
