Zida za silicone sizofunikira kwambiri pamakampani atsopano amakampani omwe akutukuka kumene, komanso ndizofunikira kwambiri pamafakitale ena omwe akutuluka kumene.

Ndikukula kosalekeza kwa magawo ogwiritsira ntchito, kufunikira kwakukulu kwapangitsa kuti ma silicones akhale amodzi mwazinthu zodziwika bwino zama mankhwala pakadali pano.

Gawo lalikulu kwambiri la ma silicones apanyumba ali m'magawo monga zomangamanga, zamagetsi, magetsi ndi mphamvu zatsopano, chithandizo chamankhwala, komanso chisamaliro chamunthu.Pakati pawo, gawo lomanga ndilo gawo lalikulu lakugwiritsa ntchito ma silicones, omwe amawerengera pafupifupi 30%.

Kuphatikiza pakukula kosalekeza kwa kufunikira kwa zida za silikoni m'mafakitale achikhalidwe, mafakitale opulumutsa mphamvu komanso chitetezo cha chilengedwe monga ma photovoltaics ndi mphamvu zatsopano, komanso kutukuka kwa mafakitale omwe akubwera monga ultra-high ndi Ultra-high voltage yomanga gridi yamagetsi. , zida zovala zanzeru, kusindikiza kwa 3D, ndi 5G, zonse zimapereka malo atsopano ofunikira a ma silicones.

Chidule cha Silicones

Ma silicones ndi mawu omwe amagwiritsidwa ntchito popanga silicon organic compounds, omwe amapangidwa ndi hydrolyzed ndi zitsulo zachitsulo ndi chloromethane.

Gawo loyamba popanga silicones ndikupanga methylchlorosilane, yomwe imapangidwa ndi hydrolyzed kuti ipeze monomethyltrichlorosilane, dimethyldichlorosilane, ndi trichlorosilane.Dimethyldichlorosilane ndiye mtundu waukulu wa silicon organic, womwe umakhala ndi mphira wa silikoni ndi mafuta a silicone.

Pakalipano, mphamvu yopanga silicones yomwe imatchulidwa ku China nthawi zambiri imatanthawuza mphamvu ya kupanga methylchlorosilane, pamene ziwerengero zamakono zonse zimachokera ku kupanga dimethylsiloxane.

Silicones industry unyolo

Unyolo wamakampani a silicone umagawidwa m'malumikizidwe anayi: zopangira ma silicones, ma silicone monomers, ma silicones intermediates, ndi zinthu zakuya za silicone.Pali mabizinesi ochepera opangira zida zopangira, ma monomers, ndi zapakatikati, pomwe kutsika kwakuya kwakuya kumaphatikizapo zinthu zambiri komanso kuchuluka kobalalika kopanga.

Silicone zopangira

Njira yopangira ma silicones imaphatikizapo kuchuluka kwazinthu zopangira.Silicones zopangira ndi fakitale ya silicone ya ufa, yomwe imakonzedwa m'makampani pochepetsa quartz ndi coke mung'anjo yamagetsi yamagetsi.

Kupanga silikoni yamafakitale kumawononga miyala yambiri ya silikoni ndi mphamvu, ndipo kumayambitsa kuipitsidwa kwakukulu kwa chilengedwe.Chifukwa chake, kukhazikika komanso kudalirika kwazinthu zopangira silikoni zamafakitale kwakhala chitsimikizo choyambirira chopangira ma silicones.

Malinga ndi SAGSI, mu 2020, mphamvu yopanga silikoni padziko lonse lapansi inali matani 6.23 miliyoni, pomwe China idapanga matani 4.82 miliyoni, zomwe zidakwana 77.4%.

Silicones monomers ndi intermediates

Kupezeka kwapakhomo kwa ma silicones monomers ndi apakatikati kumapitilira 50% yapadziko lonse lapansi, ndikupangitsa kuti ikhale yogulitsa kwambiri ma silicone monomers ndi apakatikati padziko lonse lapansi.Chifukwa chakusakhazikika kwa ma silicones monomers, makampani nthawi zambiri amaphatikiza ma monomers kukhala apakati monga DMC (dimethylsiloxane) kapena D4 ogulitsa.

Pali mitundu yochepa komanso mawonekedwe a silicone monomers ndi intermediates.

Dimethyldichlorosilane pakadali pano ndiyomwe imagwiritsidwa ntchito kwambiri pa silicone monomer, yomwe imawerengera 90% ya kuchuluka kwa monomer.

Malo olowera kumakampani a silicone ndi okwera, omwe adakwezedwa mpaka matani 200000 ndipo amafunikira ndalama zosachepera 1.5 biliyoni yandalama.Kukwera kwambiri kwamakampani kudzalimbikitsa mayendedwe amphamvu yopanga ma monomer kupita kumabizinesi otsogola.

Pakalipano, makampani ochepa okha ndi omwe ali ndi luso lokwanira laukadaulo ndipo akwanitsa kupanga zazikulu, zopitilira 90% zamphamvu zopanga zomwe zimagawidwa m'mabizinesi 11 apamwamba.

Kuchuluka kwa ma silicones monomer kupanga kumaperekanso mwayi wokwanira wokambirana m'mabizinesi akumunsi.

Dichlorodimethylsilane

Pankhani yopereka, mabizinesi ambiri otsogola a silicone ku China ali ndi ma projekiti omwe akupitilira kapena mapulani atsopano.Kuthekera kwatsopano kumeneku kudzakhazikika pakupanga kuyambira 2022 mpaka 2023, ndipo mphamvu zopangira mafakitale zatsala pang'ono kulowa m'njira yokulirakulira.

Malinga ndi deta yochokera ku Baichuan Yingfu, makampani monga Hesheng Silicon Industry, Yunnan Energy Investment, ndi Dongyue Silicon Materials adzayika ndalama zokwana matani pafupifupi 1.025 miliyoni a silicones kupanga chaka chino.Makampani monga New Special Energy, Asia Silicon Industry, ndi Sichuan Yongxiang akupanganso ndalama popanga silicon ya polycrystalline, ndikupangitsa kuti chiwonjezeko cha kufunikira kwa ma silicones aku mafakitale.

SAGSI ikuneneratu kuti mphamvu yaku China yopanga ma silicones methyl monomers ipitilira matani 6 miliyoni / chaka pofika 2025, zomwe zikuyembekezeka kupitilira 70% yapadziko lonse lapansi yopanga ma silicones methyl monomers.

Malinga ndi C&EN, Momentive, kampani yotsogola yakunja ya silikoni ikufuna kutseka mphamvu zake zopangira ma silicones ku Waterford, New York, ndikupangitsa Dow kukhala yokhayo yopanga ma silicones kumtunda ku United States.

Mphamvu yapadziko lonse lapansi yopanga ma silicones monomer imasamutsidwa kupita ku China, ndipo chiwopsezo chamakampani chidzapitilira kukula mtsogolo.

Kukonzekera kwakuya kwa silicones

Zogulitsa za silicone zozama kwambiri zimapezeka mumtundu wa RnSiX (4-n), komanso mawonekedwe okhazikika a physicochemical a tcheni cha silicon komanso kusiyanasiyana kwamagulu ogwira ntchito kumapangitsa kuti zinthu za silicone zokonzedwa mozama zikhale ndi ntchito zambiri zogwiritsira ntchito.Zogulitsa zazikulu ndi mphira wa silikoni ndi mafuta a silikoni, owerengera 66% ndi 21% motsatana.

Pakali pano, makampani akuya processing silikoni akadali mu siteji mofulumira chitukuko, ndi makampani ndi omwazikana.Pali mabizinesi opitilira 3,000 otsika kwambiri omwe amangopanga silikoni.

Kapangidwe kazinthu zozama za silicones ku China:

Makampani a silikoni akumayiko akunja alibe phindu lamtengo wapatali popanga ma silicone monomers poyerekeza ndi makampani aku China, ndipo makampani ambiri otsogola akunja akunja amayang'ana kwambiri kupanga zinthu zopangira zinthu zakuya ndikukulitsa unyolo wamafakitale.

Mfundo zolimbikitsa za China pamakampani opanga ma silikoni zasintha pang'onopang'ono kuchoka pakupanga makina a monomer kupita ku kukonza mozama kwa zinthu za silikoni, kupanga zinthu zatsopano za silikoni, kukulitsa minda yatsopano yogwiritsira ntchito, ndikuwongolera magwiridwe antchito.

Silika

Zogulitsa zam'munsi za silicone zili ndi mtengo wowonjezera wowonjezera komanso mwayi wogwiritsa ntchito msika.Pakalipano, pali mwayi waukulu wopititsa patsogolo kagwiritsidwe ntchito ka silicones m'misika yomwe ikubwera ku China ndi kunja.
