I kēia manawa, ke neʻe nei ʻo Kina i ka pahuhopu o ka peak peak a me ka neutralization carbon, e hoʻopau ana i kāna mau kalapona kalapona ponoʻī ma o ka mālama ʻana i ka ikehu a me ka hoʻemi ʻana.Ma ke kaʻina o ka pane ʻana i ka hoʻomohala ʻana o ka hale ʻōmaʻomaʻo a me ka pahu kalapona kiʻekiʻe, lawe ka ʻoihana pōhaku i nā manawa kūpono a hāʻawi i nā haʻawina kūpono i ka piko kalapona a me ka neutralization kalapona ma o ka ʻenehana ʻenehana a me nā huahana hou.
Ma ke ʻano o ka hoʻololi ʻana i ka pōhaku maoli, hoʻomaikaʻi ka pōhaku artificial i ka nui o ka hoʻohana ʻana i ka pōhaku maoli a hoʻemi i ke kaomi ʻana i ke kaiapuni kūlohelohe.ʻO ka maikaʻi o ka hoʻohana piha ʻana i nā kumuwaiwai he mea nui ka pōhaku i hana ʻia e ke kanaka i ka mālama ʻana i ke kaiapuni a me ka mālama ʻana i ka ikehu.He mea hale ʻōmaʻomaʻo maoli ia a me nā mea pale kaiapuni hou.
Wahi a ka ʻike lehulehu, ʻaʻole pono ka hana ʻana a me ke kaʻina hana o nā pōhaku artificial i ke ahi wela kiʻekiʻe.Ke hoʻohālikelike ʻia me nā ceramics, cement a me nā huahana aniani, he haʻahaʻa loa ka hoʻohana ʻana i ka ikehu i ke kaʻina hana, kahi e hoʻemi nui ai i ka hoʻohana ʻana i ka ikehu no kēlā me kēia huahana huahana a kōkua i ka mālama ʻana i ka ikehu a me ka emi ʻana o ka hoʻokuʻu ʻana;Eia kekahi, ʻo ka ikehu i hoʻopau ʻia i ke kaʻina holoʻokoʻa o ka hana a me ka hana ʻana he ikehu uila.ʻOiai ʻo kahi hapa o ka ikehu uila mai ka mana wela i kēia manawa, hiki ke hele mai ka ikehu uila e hiki mai ana mai ka mana makani, photovoltaic power generation, nuclear power, etc.
Eia kekahi, ʻo ka ʻike resin i ka pōhaku artificial he 6% a 15%.ʻO ka resin polyester unsaturated i hoʻohana ʻia i kēia manawa no loko mai o nā huahana hoʻomaʻemaʻe ʻaila, e like me ka hoʻokuʻu ʻana i ka "carbon" i kanu ʻia i loko o ke ʻano, e hoʻonui ana i ke kaomi o ke kalapona;I ka wā e hiki mai ana, ʻo ke ʻano hoʻomohala o ka pōhaku artificial R&D e hoʻohana mālie i ka resin biological, a ʻo ke kalapona i loko o nā mea kanu mai ke kalapona kalapona i ka lewa.No laila, ʻaʻohe puka kalapona hou ka resin biological.
Hiki ke hoʻokaʻawale ʻia ka pōhaku hoʻonani hale i ka pōhaku maoli a me ka pōhaku i hana ʻia e ke kanaka.Me ka hoʻomaikaʻi ʻana i ka ʻai a me ka piʻi ʻana o ka manaʻo o ke kūkulu ʻana i nā mea hoʻonaninani maikaʻi, ʻo ka pōhaku i hana ʻia e ke kanaka me nā pono he nui ke loaʻa ka manaʻo nui mai ka hui.I kēia manawa, hoʻohana nui ʻia ka pōhaku artificial i ke kahua o ka hoʻonaninani kūloko me nā countertops e like me ka lumi kuke, ka hale ʻauʻau a me ka hale ʻaina lehulehu.
▲ aia he 7145 mau ʻoihana "pōhaku hana" ma Kina, a ua hāʻule ka nui o ka hoʻopaʻa inoa ʻana i ka hapa mua o 2021.
Hōʻike ka ʻikepili noiʻi ʻoihana i kēia manawa, aia 9483 "pōhaku hana" pili i nā ʻoihana i hoʻopaʻa inoa ʻia ma Kina, nona ka 7145 e noho nei a ma ka ʻoihana.Mai 2011 a 2019, ua hōʻike ka hoʻopaʻa inoa ʻana o nā ʻoihana pili i kahi ʻano piʻi.Ma waena o lākou, ua hoʻopaʻa inoa ʻia nā ʻoihana pili 1897 ma 2019, a hiki i ka 1000 no ka manawa mua, me ka piʻi ʻana o ka makahiki he 93.4%.ʻO Guangdong, Fujian a me Shandong nā panalāʻau ʻekolu me ka nui o nā ʻoihana pili.ʻO 64% o nā ʻoihana i loaʻa kahi kapikala i hoʻopaʻa ʻia ma lalo o 5 miliona.
I ka hapa mua o 2021, 278 mau ʻoihana pili i hoʻopaʻa inoa ʻia ma ka ʻāina holoʻokoʻa, kahi hōʻemi o ka makahiki ma ka makahiki he 70.6%.ʻOi aku ka haʻahaʻa o ka helu inoa mai Ianuali a Iune ma mua o ka manawa like o ka makahiki i hala, ʻo ia ka nui o ka hoʻopaʻa inoa ʻana mai ʻApelila a Iune ma lalo o ka hapakolu o ka makahiki i hala.E like me kēia ʻano, hiki ke hāʻule nui ka nui o ka hoʻopaʻa inoa no ʻelua mau makahiki.

Hōʻike ka ʻikepili noiʻi ʻoihana ʻo Guangdong Province ka helu nui loa o nā ʻoihana pili i ka "pohaku hana", me ka huina o 2577, a ʻo ia wale nō ka ʻāina me ka ʻoi aku o 2000. ʻO Fujian a me Shandong Province ka lua a me ke kolu me 1092 a me 661 pakahi.
