Ukungena kwihlabathi lobuchwepheshe be-green silicon carbide micropowder
Etafileni yelebhu yefektri eZibo, eShandong, ingcali uLao Li uthatha iqhekeza elincinci le-emerald green powder ene-tweezers. “Le nto ilingana nezixhobo ezintathu ezingeniswe kwamanye amazwe kwindawo yethu yokusebenzela.” Wajonga phantsi waza wancuma. Lo mbala we-emerald yi-silicon carbide micropowder eluhlaza eyaziwa ngokuba “ngamazinyo emizi-mveliso”. Ukususela ekusikweni kweglasi ye-photovoltaic ukuya ekugayweni kwe-chip substrates, le nto imangalisayo enobukhulu be-particle engaphantsi kwekhulu leenwele ibhala intsomi yayo kwidabi lesayensi netekhnoloji entsha.
1. Ikhowudi yetekhnoloji emnyama esantini
Ukungena kwindawo yokusebenzela yemveliso yei-micropowder eluhlaza ye-silicon carbide, into ekuchukumisayo asikothuli olucingelwayo, kodwa yingxangxasi eluhlaza enokukhanya kwesinyithi. Ezi mpuphu ezinobukhulu obuphakathi besuntswana ezi-3 microns kuphela (ezilingana namasuntswana e-PM2.5) zinobunzima obuyi-9.5 kwisikali seMohs, zilandela iidayimani kuphela. UMnu. Wang, umlawuli wezobugcisa wenkampani eLuoyang, eHenan, unobuchule obukhethekileyo: thabatha isuntswana le-micropowder uze ulifefe ephepheni le-A4, kwaye ungabona isakhiwo sekristale esiqhelekileyo esinamahexagonal ngeglasi yokukhulisa. “Ziikristale ezipheleleyo ezingaphezu kwe-98% kuphela ezinokubizwa ngokuba ziimveliso ezisemgangathweni ophezulu. Oku kungqongqo kakhulu kunomnyhadala wobuhle.” Utshilo ngelixa ebonisa iifoto ze-microscopic kwingxelo yokuhlolwa komgangatho.
Kodwa ukuguqula ilitye libe yintshatsheli yezobuchwepheshe, i-natural enigment yodwa ayanelanga. "I-directional crushing technology" eyaphunyezwa yilabhoratri kwiPhondo laseJiangsu kunyaka ophelileyo yonyuse ukusebenza kakuhle kokusika i-micro-powder nge-40%. Balawula amandla e-electromagnetic field e-crusher ukuze banyanzele i-crystal ukuba iqhekeke kwi-crystal plane ethile. Kanye "njengokudubula inkomo ngaphesheya kwentaba" kwiinoveli zobugcisa bokulwa, ukutyumza okwenziwa ngoomatshini okubonakala ngathi kunamandla ngokwenene kufihla ulawulo oluchanekileyo lwe-molecular-level. Emva kokuba obu buchwepheshe buqalisiwe, izinga lemveliso yokusika iglasi ye-photovoltaic lenyuke ngqo ukusuka kwi-82% ukuya kwi-96%.
2. Uguquko olungabonakaliyo kwindawo yokuvelisa
Kwisiseko semveliso eXingtai, eHebei, isithando somlilo esinemigangatho emihlanu sikhupha amalangatye aqaqambileyo. Xa ubushushu besithando bubonisa i-2300℃, ingcali uXiao Chen wacinezela iqhosha lokuphakela ngokungqongqo. “Ngeli xesha, ukutshiza isanti ye-quartz kufana nokulawula ubushushu xa upheka.” Wakhomba i-jumping spectrum curve kwisikrini sokujonga waza wachaza. Inkqubo yolawulo ekrelekrele yanamhlanje inokuhlalutya umxholo wezinto ezili-17 kwisithando ngexesha langempela kwaye ilungise ngokuzenzekelayo umlinganiselo we-carbon-silicon. Kunyaka ophelileyo, le nkqubo yavumela izinga labo lemveliso yeprimiyamu ukuba lidlule kumanqaku angama-90%, kwaye inqwaba yenkunkuma yancitshiswa ngokuthe ngqo zizibini kwisithathu.
Kwiworkshop yokulinganisa, umatshini wokuhlunga umoya weturbine onobubanzi obuziimitha ezisibhozo wenza “igolide echibini lolwandle”. “Indlela yokuhlunga enemilinganiselo emithathu” eyenziwe lishishini laseFujian yahlula i-micropowder ibe ziiklasi ezili-12 ngokulungelelanisa isantya sokuhamba komoya, ubushushu, ukufuma, kunye netshaja. Imveliso ye-mesh eyi-8000 engcono kakhulu ithengiswa ngaphezulu kwe-200 yuan ngegram, eyaziwa ngokuba yi-“Hermes in powder”. Umlawuli weworkshop uLao Zhang wahlekisa ngesampulu eyayisandula ukuphuma emgceni: “Ukuba oku kuchithwe, kuya kuba buhlungu ngaphezu kokuchitha imali.”
3. Imfazwe yexesha elizayo yokuvelisa izinto ezikrelekrele eziluhlaza
Xa sijonga emva kwindawo apho ubuchwepheshe kunye nemizi-mveliso zihlangana khona, ibali le-green silicon carbide micropowder lifana nembali yokuvela kwehlabathi elingabonakaliyo. Ukusuka kwisanti kunye negrabile ukuya kwizinto ezisemgangathweni, ukusuka kwiindawo zokuvelisa ukuya kwiinkwenkwezi nolwandle, olu chukumiso loluhlaza lungena kwi-capillaries yemizi-mveliso yanamhlanje. Njengoko umlawuli wophando nophuhliso we-BOE wathi: “Ngamanye amaxesha ayizizo iingxilimbela ezitshintsha ihlabathi, kodwa ziisuntswana ezincinci ongenakuzibona.” Njengoko iinkampani ezininzi ziqala ukungena kweli hlabathi lingabonakaliyo, mhlawumbi imbewu yotshintsho lwetekhnoloji olulandelayo ifihliwe kumgubo oluhlaza ocwebezelayo phambi kwamehlo ethu.
