1. Iyini i-silicon yensimbi?
I-Metal Silicon, eyaziwa nangokuthi i-Silicon Yezimboni, ingumkhiqizo we-Silicon Dioxide kanye ne-Carbonaceous ekhuphukayo ekhuthazayo esithandweni se-Arc esingenisiwe. Ingxenye eyinhloko yeSilicon imvamisa ingaphezulu kwama-98.5% nangaphansi kwama-99.99%, futhi ukungcola okusele kuyinsimbi, i-aluminium, i-calcium, njll.
E-China, i-Metal Silicon ivame ukuhlukaniswa ngamamaki ahlukene njenge-553, 441, 421, 3303, 2203, 1102, 1101, njll., Ahlukaniswe yi-calcium.
2. Inkambu yesicelo se-silicon yensimbi
Izicelo ezaphansi ze-silicon zensimbi ikakhulukazi ziyi-silicon, polysilicon kanye ne-aluminium alloys. Ngo-2020, ukusetshenziswa okuphelele kweChina kungamathani ayizigidi eziyi-1,6, futhi isilinganiso sokusetshenziswa simi ngalendlela elandelayo:
Silica gel has high requirements on metal silicon and requires chemical grade, corresponding to model 421#, followed by polysilicon, commonly used models 553# and 441#, and aluminum alloy requirements are very low.
Kodwa-ke, eminyakeni yamuva nje, isidingo sePolysilicon e-Organic Silicon sikhuphukile, futhi ingxenye yaso isiphenduke inkulu futhi inkulu. Isidingo se-Aluminium Alloys asikhuphuki kuphela, kepha sehle. Lokhu futhi kuyinto enkulu edala ukuthi umthamo wokukhiqizwa wensimbi we-silicon ubonakale uphakeme, kepha izinga lokusebenza liphansi kakhulu, futhi kunokushoda okukhulu kwe-silicon ephezulu yensimbi emakethe.
3. Isimo Sokukhiqiza ngo-2021
Ngokusho kwezibalo, kusukela ngoJanuwari kuya kuJulayi 2021, ukuthunyelwa kwama-Silicon Metal Expon kwafinyelela amathani angama-466,000, ukunyuka konyaka ngo-41%. Ngenxa yentengo ephansi ye-silicon yensimbi eChina eminyakeni embalwa edlule, ehambisana nokuvikelwa kwemvelo kanye nezinye izizathu, amabhizinisi amaningi aphezulu anezilinganiso eziphansi noma avale ngqo.
Ngo-2021, ngenxa yokuthola ngokwanele, izinga lokusebenza le-silicon yensimbi lizoba ngaphezulu. Ukuhlinzekwa kwamandla akwanele, futhi izinga lokusebenza le-silicon yensimbi liphansi kakhulu kunaseminyakeni edlule. I-Silicon-Side Silicon ne-polysilicon kuphapheme okufushane kulo nyaka, ngamanani aphezulu, amanani aphezulu okusebenza, kanye nesidingo esandayo se-silicon yensimbi. Izici eziphelele ziholele ekushoneni okukhulu kwe-silicon yensimbi.
Okwesine, umkhuba wesikhathi esizayo we-silicon yensimbi
Ngokwesimo sokuhlinzekwa kanye nesimo semfuno esihlaziywe ngenhla, inkambiso yesikhathi esizayo ye-silicon yensimbi ikakhulukazi incike kwikhambi lezici ezedlule.
Okokuqala, ukukhiqizwa kwe-zombie, intengo ihlala iphakeme, futhi ukukhiqizwa okuthile kwe-zombie kuzokuqala ukukhiqizwa, kepha kuzothatha isikhathi esithile.
Okwesibili, ama-curbs wamandla akhona kwezinye izindawo asaqhubeka. Ngenxa yokuhlinzekwa kwamandla anganele, amanye amafektri e-silicon ayaziswa ngokuncishiswa kwamandla. Njengamanje, kusenezinhla zezimboni ze-silicon ezivaliwe, futhi kunzima ukuzibuyisela esikhathini esifushane.
Okwesithathu, uma amanani entengo ezifuywayo ahlala ephezulu, ukuthekelisa kulindeleke ukuthi kunciphe. I-Silicon yensimbi yaseChina ihanjiswa kakhulu emazweni ase-Asia, yize kungavamile ukuthunyelwa emazweni aseYurophu naseMelika. Kodwa-ke, ukukhiqizwa kwe-silicon yezimboni zaseYurophu kukhuphuke ngenxa yamanani aphezulu omhlaba wonke. Eminyakeni embalwa edlule, ngenxa yenzuzo yezindleko zasekhaya zaseChina, ukukhiqizwa kwe-silicon metal kwaba nethuba eliphelele, futhi ivolumu yokuthumela lalinkulu. Kepha lapho amanani ephakeme, ezinye izifunda nazo zizothuthukisa amandla okukhiqiza, kanye nokuthekelisa kuzokwehla.
Futhi, ngokuya ngesidingo esiphansi, kuzoba nokukhiqizwa okwengeziwe kwe-silicon kanye ne-polysilicon engxenyeni yesibili yonyaka. Ngokuya nge-polysilicon, umthamo wokukhiqiza ohleliwe kwikota yesine yalo nyaka cishe amathani angama-230,000, futhi isidingo sonke se-silicon sensimbi kulindeleke ukuthi sibe ngamathani angama-500,000. Kodwa-ke, imakethe yabathengi yokugcina yomkhiqizo kungenzeka ingadli umthamo omusha, ngakho-ke izinga lokusebenza eliphelele lekhono elisha lizokwehla. Ngokuvamile, ukushoda kwensimbi ye-silicon kulindeleke ukuthi kuqhubeke phakathi nonyaka, kepha igebe ngeke libe likhulu ikakhulukazi. Kodwa-ke, engxenyeni yesibili yonyaka, izinkampani zeSilico nePolysilicon ezingahileli i-silico yensimbi zizobhekana nezinselele.
