Kupinda munyika yetekinoroji yegreen silicon carbide micropowder
Tafura yerabhoritari yefekitori muZibo, Shandong, nyanzvi Lao Li ari kutora hupfu hwegirini reemerald hune tweezers. "Chinhu ichi chakaenzana nemidziyo mitatu inopinzwa kunze kwenyika muworkshop yedu." Akatswinya maziso ndokunyemwerera. Ruvara urwu rweemerald igirini resilicon carbide micropowder inozivikanwa se "mazino eindasitiri". Kubva pakucheka girazi re photovoltaic kusvika pakukuya machip substrates, chinhu ichi chemashiripiti chine saizi yetsumbu iri pasi pezana rebvudzi chiri kunyora ngano yacho panhandare yehondo yekuvandudza kwesainzi netekinoroji.
1. Kodhi yetekinoroji nhema mujecha
Kupinda muworkshop yekugadzira yeupfu hwegirini hwesilicon carbide, chinokushamisa hachisi guruva rinofungidzirwa, asi mapopoma egirini ane kupenya kwesimbi. Upfu uhwu hune avhareji yehukuru hwema microns matatu chete (hwakaenzana nePM2.5 particles) hune kuomarara kwe9.5 pachikero cheMohs, huchitevera madhaimani chete. VaWang, director wehunyanzvi wekambani iri muLuoyang, Henan, vane hunyanzvi hwakasiyana: tora hupfu hushoma hwe micropowder wohusasa pabepa reA4, uye unogona kuona chimiro chekristaro che hexagonal chakajairika negirazi rinokudza. "Makristaro chete ane kukwana kweanopfuura 98% ndiwo anogona kunzi zvigadzirwa zvemhando yepamusoro. Izvi zvakaoma kupfuura makwikwi erunako." Vakadaro vachiratidza mifananidzo ye microscopic iri pamushumo wekuongorora mhando.
Asi kushandura majecha kuita tekinoroji yekutanga, simba rezvisikwa chete harina kukwana. "Tekinoroji yekupwanya inotungamira" iyo rabhoritari muJiangsu Province yakaburitsa gore rapfuura yakawedzera kushanda kwekucheka kwehupfu hudiki ne40%. Vakadzora simba remagetsi remuchina wekupwanya kuti vamanikidze kristaro kuti ipwanye mudenga rekristaro rakati. Kungofanana ne "kupfura mombe mugomo" mumabhuku ehunyanzvi hwehondo, kupwanya kwemuchina kunoratidzika kunge kwakasimba kunoviga kutonga kwakanyatsojeka kwemazinga emamorekuru. Mushure mekunge tekinoroji iyi yatanga kushanda, mwero wekukohwa kwekucheka kwegirazi re photovoltaic wakakwira zvakananga kubva pa82% kusvika pa96%.
2. Kuchinja kusingaonekwe panzvimbo yekugadzira
Pachigadziko chekugadzira muXingtai, Hebei, vira re arc rine nhurikidzwa shanu riri kuburitsa moto unopenya. Panguva iyo tembiricha yevira yairatidza 2300℃, nyanzvi Xiao Chen akadzvanya bhatani rekudya. "Panguva ino, kusasa jecha re quartz kwakafanana nekudzora kupisa paunenge uchibika." Akanongedzera ku curve yekusvetuka pachidzitiro chekutarisa ndokutsanangura. Sisitimu yekudzora yanhasi ine hungwaru inogona kuongorora zviri mukati mezvinhu gumi nenomwe muvira munguva chaiyo uye kugadzirisa otomatiki chiyero che carbon-silicon. Gore rapfuura, sisitimu iyi yakabvumira mwero wavo wepamusoro wezvigadzirwa kuti upfuure ne90%, uye murwi wemarara wakaderedzwa zvakananga nezvikamu zviviri kubva muzvitatu.
Muworkshop yekuyera, muchina wekurongedza mhepo yeturbine une dhayamita yemamita masere uri kuita "gold panning mugungwa rejecha". "Nzira yekurongedza yezvikamu zvitatu" yakagadzirwa nekambani yeFujian inoparadzanisa micropowder kuita magiredhi gumi nemaviri nekugadzirisa kumhanya kwemhepo, tembiricha, hunyoro, uye chaji. Chigadzirwa chakanakisa che8000 mesh chinotengeswa neanopfuura 200 yuan pagiramu, inozivikanwa se "Hermes in powder". Mutungamiriri weworkshop Lao Zhang akaseka nemuenzaniso wakanga wangobuda mugwara achiti: "Kana izvi zvikadururwa, zvicharwadza kupfuura kudururwa kwemari."
3. Hondo yeramangwana yekugadzira zvinhu zvine hungwaru zvegirini
Tichitarisa kumashure pakusangana kwetekinoroji nemaindasitiri, nyaya yegreen silicon carbide micropowder yakafanana nenhoroondo yekushanduka-shanduka kwenyika isingaonekwe nemaziso akawanda. Kubva kujecha nejecha kusvika kuzvinhu zvemazuva ano, kubva kunzvimbo dzekugadzira kusvika kunyeredzi negungwa, kubata uku kwegirini kuri kupinda mumasero etsinga dzemaindasitiri emazuva ano. Sezvakataurwa nemutungamiriri wekutsvagisa nekusimudzira weBOE: “Dzimwe nguva hazvisi hofori dzinochinja nyika, asi zvidimbu zvidiki zvausingaone.” Sezvo makambani akawanda achitanga kuongorora nyika iyi isingaonekwe nemaziso akawanda, pamwe mbeu dzekuchinja kwetekinoroji kunotevera dzakavanzwa muhupfu hwegirini hunopenya pamberi pemaziso edu.
