Mu gawo la mafakitale komwe kutentha kwambiri, dzimbiri la mankhwala, ndi kuwonongeka kwa makina sizingatheke, kusankha zinthu zoyenera zotsutsana ndi zinthu ndikofunikira kwambiri kuti zitsimikizire kukhazikika kwa ntchito, kuchepetsa ndalama zokonzera, komanso kukonza bwino ntchito. Monga njira yothetsera zotsutsana ndi zinthu zomwe zayesedwa nthawi yayitali komanso zotsika mtengo,njerwa za dongo loyaka motoakhala chisankho choyamba m'mafakitale ambiri padziko lonse lapansi. Njerwa zathu zapamwamba zadothi lopaka moto zimaphatikizapo magwiridwe antchito abwino kwambiri, kuwongolera bwino khalidwe, komanso mitengo yampikisano, zomwe zimapangitsa kuti zikhale njira yabwino kwambiri yogwiritsira ntchito zida zanu zotentha kwambiri.
Njerwa zathu za dothi loyaka moto zimapangidwa mwaluso kwambiri kuchokera ku dothi loyaka moto loyera kwambiri, kaolin, ndi zinthu zina zabwino kwambiri monga mchenga wa quartz ndi bauxite, zomwe zimakhala ndi makhalidwe abwino kwambiri. Ndi kuchuluka kwa alumina kuyambira 30% mpaka 50%, zimatha kupirira kutentha mpaka 1550°C ndikusunga umphumphu wa kapangidwe kake ngakhale m'malo otentha kwambiri. Kapangidwe kake kolimba kamatsimikizira kuti pali ma porosity ochepa, zomwe zimapangitsa kuti asidi asagwire ntchito komanso mpweya woipa ukhale wolimba - phindu lalikulu kwa mafakitale omwe amagwiritsa ntchito zinthu zowononga. Kuphatikiza apo, zinthuzi zimakhala ndi kukana kutentha kwambiri, zomwe zimatha kupirira kutentha ndi kuzizira mwachangu popanda kusweka, motero zimawonjezera nthawi yogwira ntchito ya uvuni ndi zida zina.
Kusinthasintha kwa ntchito ndi chinthu china chachikulu chomwe chimaonekera kwambiri pa njerwa zathu zadothi, zomwe zimagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana otentha kwambiri. Mumakampani opanga zitsulo, zitha kugwiritsidwa ntchito popangira ziwiya zoyaka moto, ziwiya zoyaka moto, ndi ziwiya zamagetsi, zomwe zimapereka chitetezo chodalirika cha kutentha komanso chitetezo cha dzimbiri. Mumakampani opanga zida zomangira, zimagwiritsidwa ntchito ngati zida zazikulu zoyika ziwiya za simenti ndi ziwiya zagalasi, kuonetsetsa kuti zida zikugwira ntchito bwino nthawi yayitali kutentha kwambiri. Makampani opanga petrochemical ndi mphamvu amadaliranso zidazi popanga zida zoyeretsera mafuta, ma boiler, ndi ma reactor a mankhwala. Timapereka kukula ndi magiredi okonzedwa, kuphatikiza mitundu yamphamvu komanso yotsika, kuti tikwaniritse zofunikira za zida zosiyanasiyana ndi malo ogwirira ntchito.
Munthawi ino ya chitukuko cha zinthu zobiriwira komanso zopanda mpweya woipa, njerwa zathu zadothi zimaonekera bwino chifukwa cha ubwino wawo wopanga zinthu zoteteza chilengedwe. Pogwiritsa ntchito ukadaulo wapamwamba wothira utsi wa mu uvuni (kutentha kwa sintering pafupifupi 1380°C), timawongolera bwino ntchito yopanga zinthu pamene tikuchepetsa kugwiritsa ntchito mphamvu. Pakupanga zinthu, timagwiritsa ntchito zinthu zina zopangira zinyalala zolimba monga matope ofiira osinthidwa ndi gangue ya malasha, kuchepetsa kutulutsa mpweya wa carbon ndi ndalama zopangira zinthu popanda kuwononga ubwino. Zogulitsa zathu zimagwirizana ndi miyezo yapadziko lonse lapansi yokhudza chilengedwe, kukuthandizani kukwaniritsa zofunikira pakupanga zinthu zobiriwira ndikupeza mwayi wopikisana pamsika wapadziko lonse lapansi.
Tadzipereka kupereka chithandizo chokwanira kwa makasitomala apadziko lonse lapansi, kuyambira pa upangiri waukadaulo wogulitsira zinthu zisanagulitsidwe komanso kapangidwe ka zinthu zomwe zakonzedwa kale mpaka kuwunika bwino kwambiri panthawi yopanga komanso ntchito yogulitsa pambuyo pogulitsa, kuonetsetsa kuti pali mgwirizano wabwino nthawi zonse. Njerwa zathu zadothi zatumizidwa kumayiko ndi madera ambiri, ndipo makasitomala athu m'makampani opanga zitsulo, simenti, magalasi, petrochemical ndi mafakitale ena amawadalira chifukwa cha kulimba kwawo komanso kugwiritsa ntchito bwino ndalama.
Musalole kuti zinthu zosalimba bwino zikulepheretseni kupanga zinthu. Sankhani njerwa zathu zadothi zapamwamba kwambiri kuti musangalale ndi ubwino wambiri wogwira ntchito modalirika, moyo wautali komanso kusunga ndalama. Lumikizanani nafe tsopano kuti mudziwe zambiri za zomwe zafotokozedwa, pezani mtengo waulere, ndikupeza yankho labwino kwambiri la zinthu zosalimba zomwe zikugwirizana ndi zosowa zanu zamafakitale.
