ʻO ka ʻili artificial kahi ʻano huahana plastik, e like me ka ʻili a hiki ke hoʻololi ʻia.Hoʻokumu maʻamau i ka lole, i uhi ʻia me ka resin synthetic a me nā plastic like ʻole.ʻO ka ʻili hana PVC, ka ʻili synthetic PU.
ʻO ka mea maʻamau, e pili ana i ka lole, loaʻa ka huahana ma ka uhi ʻana a i ʻole ka uhi ʻana i kahi papa o ka hui resin ma luna, a laila hoʻomehana, plasticizing, rolling a embossing.E like me ka ʻili maoli, ʻoluʻolu a paʻa i ka lole.E like me ke ʻano o ka uhi, aia nā kāmaʻa, ʻeke, etc.
Ma Kina, ua maʻa nā kānaka i ka hoʻohana ʻana.ʻO ka hoʻololi hoʻololi i hana ʻia me ka resin PVC ua kapa ʻia ʻo PVC ʻili ʻili (ma hope i kapa ʻia ʻo ka ʻili artificial);hoʻohana;ʻO ka hoʻololi hoʻololi i hana ʻia me ka resin PU ua kapa ʻia ʻo PU ʻili ʻili (ʻili PU no ka pōkole): ʻo ke kipi hana i hana ʻia me ka resin PU a me ka lole i ulana ʻole ʻia i kapa ʻia ʻo PU synthetic leather (synthetic leather no ka pōkole).
I nā makahiki i hala iho nei, ua hoʻoneʻe mālie ʻia ka ʻili ʻili a me ka ʻili synthetic o ka honua i Kina, kahi i hāpai i ka hoʻomohala wikiwiki ʻana o ka ʻili a me ka ʻili synthetic o Kina.I nā makahiki ʻelua e hiki mai ana, e hele mai ka noi hou o ka ʻili ʻili a me ka ʻili synthetic mai ka mākeke kūloko, a ʻo ka nui o ka ulu ʻana o ka ʻoihana i lalo e pili ana i 15%.Ma waena o ka ʻili hana a me ka ʻili synthetic, ka ʻili kāmaʻa, ka ʻili lako a me ka ʻili o loko o ka kaʻa ka mea nui, a me nā waiwai haʻuki ʻO nā lako kaua a me nā mea kūikawā a me nā kahua e puka mai ana.

Mai ka hiʻohiʻona o nā kahua noi haʻahaʻa, ka ʻili kāmaʻa, ka ʻili lole, ka ʻili lako a me ka ʻili ukana e lilo i ʻehā mau kahua o ka noi substrate ʻili ma Kina i 2020. lole kumu ma Kina, a hiki i 509000 tons, helu no 36.86%;A ukali ʻia e ka ʻili lole, ka ʻili lako a me ka ʻili ukana, helu ʻia no 17.60%, 17.45% a me 14.99%.
A hiki i kēia manawa, aia ma kahi o 549 mau mea hana nui o ka ʻili synthetic ma Kina.ʻO ka nui o ka mana o nā mea hana ʻelima kiʻekiʻe ma ka laina hana e pili ana i ka 6% o ka nui o ka hiki.ʻAʻole kiʻekiʻe ka mākeke o ka ʻili synthetic.ʻO nā ʻoihana ma ka ʻoihana e hahai pono i ka loina mākeke, hilinaʻi i ka ʻenehana, brand, scale, etc. e hoʻokūkū piha i ka mākeke, a he kiʻekiʻe ka mākeke o ka ʻoihana.
ʻO ka ulu ʻana o ka ʻili synthetic
I nā makahiki i hala iho nei, ua hoʻoikaika ʻia ka hoʻokūkū ma ka ʻoihana ʻili synthetic PU kūloko, a ke kū nei ka ʻoihana i ka hoʻoponopono a me ka hoʻololi ʻana ma muli o ka piʻi ʻana o ke kaomi i lalo o ka hoʻokele waiwai o ka home, ka lohi i lalo o ka noi, a me nā koi koʻikoʻi no ka palekana, ka palekana o ka nohona a me ka hana. olakino.Ua komo ka ʻoihana i ke kahua o ka hoʻoponopono hohonu, me ka polarization maopopo a hoʻonui hou i ka ʻoihana.Mai ka makahiki 2016, ua kau mua ka nānā ʻana i ka mālama ʻana i ke kaiapuni a me ka nānā palekana i nā koi kiʻekiʻe no ka hana palekana a me ka hana ʻōmaʻomaʻo o nā ʻoihana.Ua komo ka mākeke i ke kahua o ka lanakila e lawe i nā mea a pau a ikaika mau ka mea ikaika.ʻO ka hopena, ke neʻe mālie nei nā mea hoʻolako waiwai maka (nā ʻoihana kemika nui a me nā ʻāina ʻē a me nā mea hana e like me ka lole kumu) i ka monopoly centralized, a e hāʻawi ʻia i ka mana kumu kūʻai ʻoi aku ka nui.ʻO ke kūlana kūʻokoʻa o ka mana kumu kūʻai ikaika o nā mea hoʻolako i luna e kaupalena ʻia ka nui o ka loaʻa kālā o nā ʻoihana.Pono ka ʻili PVC i ka plasticizer DOP a me nā stabilizers i loaʻa nā metala kaumaha e like me ke alakaʻi a me ka cadmium, kahi maʻalahi e hoʻohaumia i ke kaiapuni.Ua helu ʻia ʻo ia ma ke ʻano he papahana hoʻomohala paʻa i ka Catalog for the Guidance of Industrial Restructuring.Eia naʻe, nā mea hoʻoheheʻe e like me ka polyurethane a me DMF, i hoʻohana nui ʻia i ka hana ʻana i ka ʻili PU, e hoʻopuka i nā mea hoʻoheheʻe maʻemaʻe (VOC), ʻaʻole pono e hoʻoikaika ikaika ʻia.ʻO ke ʻano o ka ulu ʻana o ka ʻōmaʻomaʻo a me ke kaiapuni o ka ʻili synthetic ma Kina ua maopopo loa.
