Zvishandiso zveSilicones hazvisi chete chikamu chakakosha cheindasitiri yezvigadzirwa zvitsva zveindasitiri yenyika ichiri kusimukira, asiwo chinhu chakakosha chekutsigira mamwe maindasitiri ari kusimukira.

Nekuwedzera kuri kuramba kuchienderera mberi kweminda yekunyorera, iyo yakakura yekudiwa inogona kuita kuti silicones ive imwe yeanonyanya kufarirwa makemikari zvinhu parizvino.

Chikamu chikuru chekushandiswa kwesilicones mudzimba kuri muminda yakadai sekuvaka, zvemagetsi, magetsi uye simba idzva, kurapwa, uye kutarisira wega.Pakati pavo, nzvimbo yekuvaka parizvino ndiyo huru terminal mamiriro ekushandiswa kwesilicone, inoverengera makumi matatu muzana.

Pamusoro pekuenderera mberi kwekukura kwekudiwa kwezvinhu zvesilicone mumaindasitiri echinyakare, maindasitiri ekuchengetedza simba uye ekuchengetedza kwezvakatipoteredza akadai sephotovoltaics uye simba idzva, pamwe nekuvandudzwa kwemaindasitiri ari kubuda akadai seyekupedzisira-yakakwirira-yakakwirira-yakakwirira-yakakwirira-yakakwira magetsi emagetsi grid kuvaka. , zvinhu zvakangwara zvinopfekwa, kudhinda kwe3D, uye 5G, zvese zvinopa mapoinzi matsva ekukura kwesilicones.

Mhedziso yeSilicones

Silicones ishoko rinowanzoreva silicon organic komisheni, iyo inogadzirwa uye hydrolyzed nesimbi silicon uye chloromethane.

Nhanho yekutanga mukugadzira silicones ndeyekugadzira methylchlorosilane, iyo inozoitwa hydrolyzed kuti iwane monomethyltrichlorosilane, dimethyldichlorosilane, uye trichlorosilane.Dimethyldichlorosilane ndiyo huru monomer yakasiyana-siyana yeorganic silicon, ine zvigadzirwa zvayo zvikuru zvekudzika zviri silicone rabha uye silicone mafuta.

Parizvino, iyo silicones yekugadzira simba inotaurwa muChina kazhinji inoreva kugona kwekugadzira kwemethylchlorosilane, nepo huwandu hwazvino hwekugadzira hunoenderana nekugadzirwa kwedimethylsiloxane.

Silicones industry cheni

Iyo silicones indasitiri cheni inonyanya kukamurwa kuita mana zvinongedzo: silicones raw materials, silicones monomers, silicones intermediates, uye silicones yakadzika kugadzirisa zvigadzirwa.Kune mashoma mabhizinesi ekugadzira ezvigadzirwa, monomers, uye zvepakati, nepo kudzika kwakadzika kugadzirisa kunosanganisira huwandu hwakasiyana hwezvigadzirwa uye yakawanda yakapararira kugadzirwa kwesimba.

Silicone mbishi zvinhu

Maitiro ekugadzira silicones anosanganisira chikamu chikuru chezvakagadzirwa.Iyo silicones raw material iindasitiri silicone poda, iyo inogadzirirwa muindasitiri nekudzikisa quartz necoke muchoto chemagetsi arc.

Kugadzirwa kwesilicone yeindasitiri kunopedza huwandu hwakakura hwesilicone ore uye simba, uye kukonzeresa kusvibiswa kwezvakatipoteredza.Naizvozvo, yakagadzikana uye yemhando yepamusoro yekupihwa kwemaindasitiri silicone mbishi zvinhu yave vimbiso yekutanga yekugadzirwa kwesilicone.

Sekureva kweSAGSI, muna 2020, iyo yepasi rose maindasitiri silicone yekugadzira yaisvika 6.23 miriyoni matani, nepo China yekugadzira yaisvika 4.82 miriyoni matani, achiverengera 77.4%.

Silicones monomers uye pakati

Kuwanikwa kwepamba kwesilicones monomers uye yepakati account kweanopfuura makumi mashanu muzana epasi rose, zvichiita kuti ive mutengesi mukuru wesilicones monomers uye vepakati pasirese.Nekuda kwekusagadzikana mamiriro esilicones monomers, makambani anowanzo gadzira mamonomers kuita zvepakati senge DMC (dimethylsiloxane) kana D4 iri kutengeswa.

Kune mashoma marudzi uye akatsanangurwa esilicone monomers uye epakati.

Dimethyldichlorosilane parizvino ndiyo inonyanya kushandiswa silicones monomer, inoverengera inopfuura 90% yehuwandu hwemonomer huwandu.

Iyo yekupinda indasitiri yesilicones yakakwira, iyo yakasimudzwa kusvika 200000 matani uye inoda inokwana bhiriyoni 1.5 yuan yekudyara mari.Iyo yakakwira indasitiri yekupinda chikumbaridzo inosimudzira maitiro emonomer yekugadzira huwandu hwekuisa kune anotungamira mabhizinesi.

Parizvino, vashoma chete vemakambani vane ruzivo rwakakwana rwetekinoroji uye vakawana kugadzirwa kwakakura, nepamusoro pe90% yehuwandu hwekugadzira hwakagoverwa pakati pemabhizinesi gumi nerimwe epamusoro.

Iko kusungirirwa kwesilicones monomer kugadzirwa kwesimba kunopawo yakawanda yakawandisa nzvimbo yekudyira kumabhizinesi epasi.

Panyaya yekugovera, mazhinji anotungamira silicones mabhizinesi muChina ane anoenderera mberi mapurojekiti kana zvirongwa zvitsva.Hunhu hutsva hwekugadzira huchaiswa mukugadzira kubva 2022 kusvika 2023, uye indasitiri yekugadzira hunyanzvi hwave kuda kupinda muchikamu chekuwedzera nekukurumidza.

Zvinoenderana nedata kubva kuBaichuan Yingfu, makambani akadai seHesheng Silicon Indasitiri, Yunnan Energy Investment, uye Dongyue Silicon Materials achaisa mari inosvika miriyoni imwe chete nemazana maviri ematani ematani ekugadzira silicones gore rino.Makambani akadai seNew Special Energy, Asia Silicon Indasitiri, uye Sichuan Yongxiang arikudyarawo mupolycrystalline silicon yekugadzira simba, zvichifambisa kuwedzera kwekuda kwemaindasitiri silicones.

SAGSI inofanotaura kuti kugadzirwa kweChina kwesilicones methyl monomers kuchapfuura mamirioni matanhatu ematoni/gore panosvika 2025, ichiverengera anopfuura makumi manomwe muzana epasi rose kugadzirwa kwesilicones methyl monomers.

Sekureva kweC&EN, Momentive, kambani yekunze inotungamira silicones inoronga kuvhara kugadzirwa kwayo kwesilicones muWaterford, New York, zvichiita kuti Dow ive yega inogadzira silicones kumusoro kwerukova zvinhu muUnited States.

Iyo yepasi rose silicones monomer yekugadzira huwandu inoendeswa kuChina, uye iyo indasitiri yekutarisa reshiyo icharamba ichivandudza mune ramangwana.

Deep processing of silicones

Yakadzika yakagadziriswa silicones zvigadzirwa zvinowanzovepo mune molecular fomu yeRnSiX (4-n), uye yakagadzikana physicochemical zvimiro zvesilicon cheni uye kusiyanisa kwemapoka anoshanda anopa zvakadzika zvakagadziriswa silicones zvigadzirwa zvine hupfumi hwekushandisa mabasa.Zvigadzirwa zvikuru ndeye silicone rabha uye silicone mafuta, inoverengera 66% uye 21% zvichiteerana.

Parizvino, iyo yakadzika yekugadzirisa indasitiri yesilicones ichiri mukukurumidza kusimudzira nhanho, ine indasitiri yakapararira.Kune anopfuura zviuru zvitatu zvepasi zvakadzika kugadzirisa mabhizinesi anongobatanidzwa mune silicone kugadzirisa.

Iwo Mamiriro ezvakadzama akagadzirwa silicones zvigadzirwa muChina:

Mhirizhonga makambani esilicone anoshaya mubairo wemubhadharo mukugadzira silicone monomers zvichienzaniswa nemakambani eChinese, uye mazhinji emakambani anotungamira ekunze kwesilicone anotarisa mukugadzira zvakadzika zvakadzika zvigadzirwa zvekugadzira uye kuwedzera ketani yemaindasitiri.

Mitemo yeChina yekukurudzira yeindasitiri yesilicones yachinja zvishoma nezvishoma kubva mukugadzirwa kwemonomer kuenda kune yakadzama kugadzirisa zvigadzirwa zvesilicone, kuvandudza zvigadzirwa zvitsva zvesilicone, kuwedzera kweminda mitsva yekushandisa, uye kuvandudzwa kwehuwandu hwekushandisa.
