1. Chii chinonzi simbi nesilicon?
Metal silicon, inozivikanwawo semaindasitiri silicon, chigadzirwa chekunyungudutsa silicon dioxide uye carbonaceous inoderedza mumiriri muchoto chakanyura chearc. Chinhu chikuru chesilicon chinowanzopfuura 98.5% uye pasi pe99.99%, uye tsvina yakasara isimbi, aluminium, calcium, nezvimwewo.
MuChina, simbi silicon inowanzo kupatsanurwa mumagiredhi akasiyana akadai 553, 441, 421, 3303, 2202, 1101, nezvimwewo, izvo zvinosiyaniswa zvinoenderana nezviri mukati simbi, aruminiyamu uye calcium.
2. Munda wekushandisa wesimbi silicon
Iyo yakadzika mashandisirwo esimbi silicon inonyanya kuve silicon, polysilicon uye aruminiyamu alloys. Muna 2020, kushandiswa kweChina kunosvika matani miriyoni 1.6, uye chiyero chekushandisa ndeichi:
Silica gel ine zvinodiwa zvakanyanya pasilicon yesimbi uye inoda kemikari giredhi, inoenderana nemuenzaniso 421 #, ichiteverwa nepolysilicon, inowanzoshandiswa modhi 553# uye 441#, uye aruminiyamu alloy zvinodiwa zvakaderera kwazvo.
Nekudaro, mumakore achangopfuura, kudiwa kwepolysilicon mune organic silicon kwakawedzera, uye chikamu chayo chave chakakura uye chakakura. Kudiwa kwealuminium alloys hakuna kungowedzera, asi kwakaderera. Ichi zvakare chinhu chikuru chinoita kuti silicon simbi yekugadzira simbi iite kunge yakakwira, asi mwero wekushandisa wakadzikira zvakanyanya, uye pane kushomeka kwakanyanya kwe-high-giredhi simbi silicon pamusika.
3. Mamiriro ekugadzira muna 2021
Sekureva kwehuwandu, kubva muna Ndira kusvika Chikunguru 2021, China silicon simbi inotengeswa kunze yakasvika 466,000 matani, gore negore kuwedzera kwe41%. Nekuda kwemutengo wakaderera wesimbi silicon muChina mumakore mashoma apfuura, pamwe nekuchengetedzwa kwezvakatipoteredza uye zvimwe zvikonzero, mazhinji emabhizinesi anodhura ane mitengo yakaderera yekushandisa kana kuvharwa zvakananga.
Muna 2021, nekuda kwekuwanikwa kwakakwana, mwero wekushanda wesimbi silicon uchave wakakwira. Simba rekushandisa harina kukwana, uye chiyero chekushanda kwesimbi silicon yakaderera zvakanyanya kupfuura makore apfuura. Demand-side silicon uye polysilicon zviri kushomeka gore rino, nemitengo yakakwira, mitengo yakakwira yekushandisa, uye kuwedzera kudiwa kwesimbi silicon. Comprehensive zvinhu zvakakonzera kushomeka kwakakomba kwesimbi nesilicon.
Chechina, remangwana maitiro esimbi silicon
Zvinoenderana nekupa uye kudiwa mamiriro akaongororwa pamusoro, mafambiro emangwana esimbi silicon anonyanya kuenderana nemhinduro yezvakapfuura zvinhu.
Chekutanga pane zvese, yekugadzira zombie, mutengo unoramba wakakwira, uye kumwe kugadzirwa kwe zombie kunotangazve kugadzira, asi zvinotora imwe nguva yenguva.
Chechipiri, ikozvino magetsi curbs mune dzimwe nzvimbo achiri kuenderera mberi. Nekuda kwekusakwana kwemagetsi, mamwe mafekitori esilicon akaziviswa nezvekudzimwa kwemagetsi. Parizvino, kuchine maindasitiri esilicon mavira akavharwa, uye zvakaoma kuvadzosa munguva pfupi.
Chechitatu, kana mitengo yemumba ikaramba yakakwira, zvinotengeswa kunze kwenyika zvinotarisirwa kudzikira. Simbi yeChina yesilicon inonyanya kutumirwa kunyika dzeAsia, kunyangwe isingawanzo kutumirwa kunyika dzeEurope neAmerica. Nekudaro, kugadzirwa kweEuropean maindasitiri silicon kwakawedzera nekuda kwemitengo ichangoburwa yepasi rose. Makore mashoma apfuura, nekuda kwemutengo wepamba weChina, kugadzira kweChina simbi yesilicon kwakave nemukana wakakwana, uye huwandu hwekutengesa kunze kwenyika hwakanga hwakakura. Asi kana mitengo yakwira, mamwe matunhu anowedzerawo huwandu hwekugadzira, uye kutengesa kunze kwenyika kunodzikira.
Zvakare, maererano nekudzika kwemvura kudiwa, kuchave nekuwanda silicon uye polysilicon kugadzirwa muhafu yechipiri yegore. Panyaya yepolysilicon, huwandu hwakarongwa hwekugadzira muchikamu chechina chegore rino hunosvika 230,000 matani, uye iyo yakazara kudiwa kwesimbi silicon inotarisirwa kunge inosvika mazana mashanu ezviuru ematani. Nekudaro, iyo yekupedzisira chigadzirwa musika wevatengi inogona kusashandisa hutsva hutsva, saka huwandu hwese hwekushanda hwehutsva huchadzikira. Kazhinji, kushomeka kwesimbi yesilicon kunotarisirwa kuenderera mukati megore, asi gaka harizove rakakura. Nekudaro, muhafu yechipiri yegore, silicon uye polysilicon makambani asingasanganisire simbi silicon achasangana nematambudziko.
