ʻAʻole ʻo nā mea Silicones he mea koʻikoʻi wale nō o ka ʻoihana waiwai hou o ka ʻoihana e puka mai ana i ka ʻāina, akā he mea kākoʻo koʻikoʻi no nā ʻoihana ʻē aʻe.

Me ka hoʻomau mau ʻana o nā kahua noi, ua hana ka nui o ka noi i nā silicones i kekahi o nā mea kemika kaulana loa i kēia manawa.

ʻO ka hapa nui o ka hoʻohana ʻana i ka silicones home ma nā kahua e like me ke kūkulu ʻana, ka uila, ka uila a me ka ikehu hou, ka mālama olakino, a me ka mālama pilikino.I waena o lākou, ʻo ke kahua kūkulu i kēia manawa ke ʻano kumu nui no ka hoʻohana ʻana i nā silicones, e helu ana ma kahi o 30%.

Ma kahi o ka ulu mau ʻana o ka noi no nā mea silicones i nā ʻoihana kuʻuna, mālama i ka ikehu a me nā ʻoihana mālama kaiapuni e like me ka photovoltaics a me ka ikehu hou, a me ka hoʻomohala ʻana i nā ʻoihana e kū mai ana e like me ka ultra-high a me ka ultra-high voltage power grid construction. , nā mea hoʻohana akamai, paʻi 3D, a me 5G, hāʻawi nā mea āpau i nā wahi ulu koi hou no nā silicones.

Nānā nui o nā Silicones

He huaʻōlelo maʻamau ʻo Silicones no nā mea hoʻohui kino silika, i hoʻohui ʻia a hydrolyzed e ke silikona metala a me ka chloromethane.

ʻO ka hana mua i ka synthesizing silicones ka hana ʻana i ka methylchlorosilane, a laila hydrolyzed e loaʻa ai ka monomethyltrichlorosilane, dimethyldichlorosilane, a me trichlorosilane.ʻO Dimethyldichlorosilane ka ʻano monomer nui o ka silika organik, me kāna mau huahana i lalo he silikoni a me ka aila silicone.

I kēia manawa, ʻo ka mana hana silicones i ʻōlelo ʻia ma Kina e pili ana i ka mana hana o ka methylchlorosilane, aʻo nā helu hana o kēia manawa e pili ana i ka hana o dimethylsiloxane.

kaulahao ʻoihana silicone

Hoʻokaʻawale ʻia ke kaulahao ʻoihana silicones i ʻehā mau loulou: silicones raw material, silicones monomers, silicones intermediates, a me nā huahana hoʻoili hohonu silicones.He liʻiliʻi ka liʻiliʻi o nā ʻoihana hana no nā mea maka, monomers, a me nā mea waena, ʻoiai ʻo ka hoʻoili hohonu ʻana i lalo e pili ana i kahi ākea o nā huahana a ʻoi aku ka nui o ka hiki ke hoʻolaha.

ʻO nā mea waiwai silicone

ʻO ke kaʻina hana o nā silicones e pili ana i kahi hapa nui o nā mea maka.ʻO ka silicones raw material ka pauka silicone ʻoihana, i hoʻomākaukau ʻia i ka ʻoihana ma ka hōʻemi ʻana i ka quartz me ka coke i loko o kahi umu ahi uila.

ʻO ka hana ʻana o ka silicone ʻoihana e hoʻopau i ka nui o ka ʻaila silicone a me ka ikehu, a ke kumu nui i ka pollution kaiapuni.No laila, ua lilo ka lako paʻa a me ka kiʻekiʻe o ka ʻoihana silicone maka kumu kumu kumu no ka hana silicones.

Wahi a SAGSI, i ka makahiki 2020, he 6.23 miliona tons ka nui o ka hana hana silicone, aʻo ka nui o ka hana ʻana o Kina he 4.82 miliona tons, ʻo ia ka 77.4%.

Silika

Silicones monomers a me nā mea waena

ʻO ka lako hale o nā silicones monomers a me nā mea waena e pili ana ma luna o 50% o ka huina honua, e lilo ia i mea hoʻolako nui loa i nā monomers silicones a me nā waena waena o ka honua.Ma muli o ke kūlana paʻa ʻole o nā monomers silicones, hana maʻamau nā hui i nā monomers i loko o nā mea waena e like me DMC (dimethylsiloxane) a i ʻole D4 no ke kūʻai aku.

He liʻiliʻi nā ʻano a me nā kikoʻī o nā monomers silicones a me nā waena waena.

ʻO Dimethyldichlorosilane ka monomer silicones i hoʻohana nui ʻia i kēia manawa, ʻoi aku ma mua o 90% o ka nui o ka monomer.

He kiʻekiʻe ka paepae komo no ka ʻoihana silicones, ua hoʻokiʻekiʻe ʻia i 200000 tons a koi i ka liʻiliʻi o 1.5 biliona yuan o ka hoʻopukapuka kālā.ʻO ka paepae komo ʻoihana kiʻekiʻe e hoʻolaha i ke ʻano o ka mana o ka hana monomer i nā ʻoihana alakaʻi.

I kēia manawa, he helu liʻiliʻi wale nō o nā ʻoihana i loaʻa ka hōʻiliʻili ʻenehana a loaʻa i ka hana nui, me ka ʻoi aku o 90% o ka mana hana i māhele ʻia ma waena o nā ʻoihana 11 kiʻekiʻe.

Hāʻawi ka manaʻo o ka silicones monomer production capacity i ka nui o nā wahi kūʻai aku no nā ʻoihana o lalo.

Dichlorodimethylsilane

I ka ʻōlelo o ka lako, nui nā ʻoihana silicones alakaʻi ma Kina e hoʻomau nei nā papahana a i ʻole nā ​​​​hoʻolālā hou.E hoʻopaʻa ʻia ka mana hana hou i ka hana ʻana mai 2022 a 2023, a ua kokoke ka mana hana o ka ʻoihana e komo i kahi pōʻai hoʻonui wikiwiki.

Wahi a ka ʻikepili mai Baichuan Yingfu, ʻo nā hui e like me Hesheng Silicon Industry, Yunnan Energy Investment, a me Dongyue Silicon Materials e hoʻolilo ma kahi o 1.025 miliona tons o ka hana hana silicones i kēia makahiki.ʻO nā ʻoihana e like me New Special Energy, Asia Silicon Industry, a me Sichuan Yongxiang ke hoʻopukapuka pū nei i ka mana hana silika polycrystalline, e hoʻonui ana i ka noi silicones ʻoihana.

Ua wānana ʻo SAGSI e ʻoi aku ka nui o ka hana ʻana o Kina o silicones methyl monomers ma mua o 6 miliona tons / makahiki e 2025, ʻoi aku ka nui o 70% o ka mana hana honua o silicones methyl monomers.

Wahi a C&EN, Momentive, hoʻolālā ka hui silicones alakaʻi haole e pani i kāna hana hana silicones ma Waterford, New York, e hana ana ʻo Dow wale nō ka mea hana o nā silicones upstream raw material ma United States.

Hoʻololi ʻia ka mana hana hana monomer silicones honua i Kina, a e hoʻomau ka hoʻomaikaʻi ʻana o ka ʻoihana i ka wā e hiki mai ana.

Ka hana hohonu o nā silicones

Loaʻa pinepine nā huahana silicones hohonu i loko o ke ʻano molekula o RnSiX (4-n), a ʻo nā waiwai physicochemical paʻa o ke kaulahao silika a me ka loli o nā pūʻulu hana e hāʻawi i nā huahana silicones hohonu i hoʻohana ʻia me nā hana hoʻohana waiwai.ʻO nā huahana nui he silicone rubber a me ka ʻaila silicone, helu no 66% a me 21%.

I kēia manawa, ʻo ka ʻoihana hoʻomohala hohonu o ka silicones aia nō i kahi pae hoʻomohala wikiwiki, me kahi ʻoihana hoʻopuehu.Aia ma luna o 3,000 mau ʻoihana hoʻoheheʻe hohonu i hana wale i ka hana silicone.

ʻOlivia Factory Raw Material Tank

ʻO ke ʻano o nā huahana silicones hohonu i hana ʻia ma Kina:

Loaʻa i nā ʻoihana silicone o nā ʻāina ʻē ke kumu kūʻai i ka hana ʻana i nā monomers silicone i hoʻohālikelike ʻia me nā ʻoihana Kina, a ʻo ka hapa nui o nā ʻoihana silikoni alakaʻi i waho e kālele ana i ka hoʻomohala ʻana i nā huahana hana hohonu a hoʻonui i ke kaulahao ʻoihana.

Ua neʻe mālie nā kulekele paipai a Kina no ka ʻoihana silicones mai ka hana monomer i ka hana hohonu o nā huahana silicones, ka hoʻomohala ʻana i nā huahana silicones hou, ka hoʻonui ʻana i nā kahua noi hou, a me ka hoʻomaikaʻi ʻana i ka pae hoʻohana piha.

ʻO nā huahana Silicones downstream he kiʻekiʻe ka waiwai hoʻohui huahana a me nā manaʻo noi noi mākeke.I kēia manawa, aia kahi lumi nui no ka hoʻomohala ʻana i ka hoʻohana ʻana i nā silicones i nā mākeke e kū mai ana ma Kina a ma waho.
