Gawo lililonse lokonza limasinthidwa mosinthika kutengera zofunikira zinazake zogwiritsidwa ntchito kumapeto, kuonetsetsa kuti ufa wa kaolin umapereka magwiridwe antchito abwino kwambiri m'magawo osiyanasiyana amafakitale.
Makampani opanga zomatira ndi zomatira amadalira kwambiri ufa wa kaolin kuti athetse mavuto ofunikira pakupanga zinthu m'mafakitale. Amasintha bwino kukhuthala kwa zomatira kuti zikhale zoyenera—kuletsa kugwa kapena kutsika kwa madzi panthawi yogwiritsidwa ntchito molunjika pazigawo zamakina (monga zigawo za injini) pamene akusunga kusalala koyenera kuti zigwirizane ndi mapaipi osakhazikika (omwe amapezeka m'mafakitale opanga mankhwala). Kukula kwa tinthu tating'onoting'ono tating'onoting'ono ta kaolin komanso kuthekera koyimitsa kwamphamvu kwa ufa wa kaolin kumasunga zomatirazo mofanana komanso zokhazikika panthawi yosungidwa kwa nthawi yayitali (kaya m'migolo yotsekedwa kapena machubu osinthasintha), kupewa kutayikira kapena kugawa komwe kumayambitsa mphamvu yosagwirizana yolumikizana. Ufa wa Kaolin umawonjezera mphamvu yolumikizana kudzera m'njira ziwiri: tinthu take tating'onoting'ono kwambiri timalowa mozama m'mabowo ang'onoang'ono ndi m'ming'alu ya substrates—kaya chitsulo (chitsulo, aluminiyamu), pulasitiki (polypropylene, PVC) kapena matabwa (plywood, matabwa olimba)—kupanga zolumikizira zolimba zamakina; pakadali pano, magulu ake ogwira ntchito pamwamba pake (atasinthidwa) amapanga zomangira zofooka za mankhwala ndi malo a substrate, polimbana ndi kuchotsedwa, kudulidwa ndi dzimbiri kuchokera ku mankhwala a mafakitale (monga zosungunulira ndi ma acid). Mu zotsekera zomwe zimagwiritsidwa ntchito pa zida za mankhwala (ma reactor, matanki osungira), zimathandizira kwambiri kukana kutentha ndi kukhazikika kwa mankhwala, zomwe zimathandiza kuti zotsekera zizitha kupirira malo ovuta ogwirira ntchito (kutentha kwambiri, mpweya wowononga) popanda kusweka kapena kutaya kusinthasintha, kuteteza bwino zida kuti zisatuluke ndikuwonetsetsa kuti ntchitoyo ndi yotetezeka.
Gawo la zinthu zopopera mpweya limaona kuti ufa wa kaolin ndi wokhazikika kwambiri pa kutentha komanso mphamvu yoletsa kuphulika kwa mpweya kuposa mafakitale ena onse. Mukasakaniza ndi alumina ndi magnesia m'njira zasayansi (zosinthidwa kutengera zosowa za zida zinazake), umapanga zosakaniza zapamwamba zopangira zinthu zopopera mpweya ndi zolumikizira za uvuni—zoyang'ana kwambiri pazida zofunika monga ng'anjo zosungunulira magalasi (zomwe zimagwira ntchito kutentha kwambiri) ndi ma uvuni ozungulira a simenti (zomwe zimasinthasintha kutentha nthawi zambiri). Zosakanizazi, zokhala ndi ufa wa kaolin ngati gawo lofunikira, zimatha kusunga umphumphu wokhazikika ngakhale kutentha kwambiri, ndikupanga zotchinga zolimba zomwe zimateteza makoma a ng'anjo ku kutentha kwakukulu (komwe kumachitika chifukwa cha kukwera kwadzidzidzi kwa kutentha kapena kutsika) ndi dzimbiri kuchokera ku mpweya woipa (wotulutsidwa panthawi yosungunuka kapena kusungunuka kwa mpweya). Kapangidwe kake kapadera ka ufa wa Kaolin kamadzaza mipata yaying'ono pakati pa tinthu tating'onoting'ono topopera mpweya, zomwe zimapangitsa kuti zinthu zopopera mpweya zikhale zolimba komanso kuchepetsa kutayika kwa kutentha kuchokera ku ng'anjo—kuthandiza mabizinesi kusunga mphamvu. Chofunika kwambiri, khalidwe lake labwino kwambiri loletsa kuphulika kwa mpweya limaletsa kusweka kwa zinthu kapena kusweka komwe kumachitika chifukwa cha kutentha mobwerezabwereza, kukulitsa kwambiri moyo wa ntchito ya zolumikizira zopopera mpweya ndikuchepetsa nthawi yokonza ndi ndalama zosinthira mafakitale.
Makampani opanga pulasitiki amagwiritsa ntchito ufa wa kaolin kwambiri ngati njira yolimbikitsira yotsika mtengo kuti akweze magwiridwe antchito athunthu a pulasitiki yoyambira. Akawonjezeredwa ku polypropylene ndi polyethylene (mapulasitiki omwe amagwiritsidwa ntchito kwambiri), amathandizira kwambiri kulimba kwa zinthu zapulasitiki - zomwe zimapangitsa kuti zikhale zoyenera kupanga zikwama za zida zapakhomo (mafiriji, makina ochapira) ndi ma profiles apulasitiki omanga (mafelemu a zitseko ndi mawindo). Zimathandizanso kukana kutentha kwa pulasitiki, zomwe zimathandiza kuti zigwiritsidwe ntchito popanga nyumba zamagetsi (zomwe zimapangitsa kutentha panthawi yogwira ntchito) popanda kusintha. Kuphatikiza apo, ufa wa kaolin umathandizira kukhazikika kwa pulasitiki, kupewa kupindika kapena kuchepa pambuyo poumba - ndikofunikira kwambiri pazigawo za pulasitiki zolondola. Ufa wa kaolin wosinthidwa pamwamba ukhoza kufalikira mofanana m'magawo a polima, ndikupanga zomangira zolimba zomwe zimawonjezera kukana kwamphamvu pomwe zikusunga kusalala kwa pamwamba - kofunikira pazinthu zomwe zimaoneka bwino (monga zigawo zokongoletsera pulasitiki). Chofunika kwambiri, chimagwirizana kwathunthu ndi njira zomwe zilipo zotulutsira ndi zopangira jakisoni, zomwe zimathandiza opanga kugwiritsa ntchito zida zomwe zilipo popanda kusintha kwina kapena ndalama zopangira.
Makampani opanga zinthu zophatikizika amagwiritsa ntchito ufa wa kaolin kuti agwirizane bwino ndi magwiridwe antchito, mtengo ndi kulemera—zofunika zitatu zazikulu popanga zinthu zophatikizika. Mu zinthu zophatikizika zolimbikitsidwa ndi ulusi zomwe zimagwiritsidwa ntchito pa masamba a turbine yamphepo (omwe amafunikira mphamvu zambiri komanso kulemera kopepuka) ndi zida zopepuka zamagalimoto (zomwe cholinga chake ndi kuchepetsa kugwiritsa ntchito mafuta), ufa wa kaolin umagwira ntchito ngati chodzaza chomwe sichimangowonjezera kuuma, kukana kutopa komanso kukhazikika kwa zinthu zophatikizika komanso kuchepetsa kulemera konse. Ukhoza kusintha gawo la ulusi wokwera mtengo wa kaboni kapena ulusi wagalasi muzinthu zophatikizika, kumachepetsa kwambiri ndalama zopangira popanda kuwononga mphamvu ya kapangidwe kake. Tinthu tofanana ndi mbale ya ufa wa Kaolin tingagwirizane ndi matrix ophatikizika panthawi yokonza, kupanga "network yolimbitsa lamellar" yomwe imawongolera kugawa kwa kupsinjika—kusamutsa bwino mphamvu zakunja kuzinthu zophatikizika za ulusi, kupewa kuwonongeka komwe kumachitika (monga kusweka kwa ulusi kapena kusweka kwa matrix) ndikuwonjezera moyo wautumiki wa zinthu zophatikizika pansi pa katundu wozungulira wa nthawi yayitali (wofala pakugwira ntchito kwa turbine yamphepo ndi kuyendetsa magalimoto).
Gawo losintha phula (ntchito yatsopano yosiyana ndi zolemba zakale) limagwiritsa ntchito ufa wa kaolin mosangalala chifukwa cha luso lake lapadera lokweza magwiridwe antchito a misewu mokwanira. Likawonjezeredwa ku zosakaniza za phula (zinthu zazikulu zomangira misewu), limawonjezera kwambiri kukhazikika kwa phula kutentha kwambiri, kuchepetsa chiopsezo cha mayendedwe (opangidwa ndi magalimoto ambiri) m'misewu m'malo otentha (monga madera otentha kapena otentha). Kapangidwe kake ka lamellar kangapange netiweki yolimba yoteteza mu phula, kukonza magwiridwe antchito oletsa ukalamba (kukana kusungunuka kwa dzuwa ndi mpweya) komanso kukana madzi (kuletsa madzi kulowa mumsewu) - zomwe zimakulitsa kwambiri moyo wa ntchito za misewu. Ufa wa Kaolin umakonzanso kukhuthala kwa phula kukhala koyenera, ndikuwonjezera magwiridwe antchito omanga (kupangitsa kuti zikhale zosavuta kupanga phula ndi kuphatikizika) popanda kukhudza kuuma komaliza kwa pamwamba pa misewu. Ntchitoyi imagwiritsidwa ntchito kwambiri pomanga misewu yayikulu ndi yamatauni, makamaka m'mapulojekiti ofunikira kulimba kwambiri (monga misewu yayikulu ndi misewu ya eyapoti), kukwaniritsa bwino zofunikira za zomangamanga zodalirika komanso zokhalitsa.
