Zikafika kumadera otentha kwambiri, kuyambira ng'anjo zamafakitale kupita kumalo okhalamo, chinthu chimodzi chimadziwika ngati msana wa kukhulupirika kwamapangidwe:dongo refractory matope. Mutondo wapaderawu umapangidwa kuti usapirire kutentha kwambiri, kukokoloka kwa mankhwala, ndiponso kutenthedwa ndi kutentha, sumangokhalira kungokhala ngati “glue” wa njerwa zomangira njerwa. Ndi gawo lofunikira lomwe limatsimikizira chitetezo, magwiridwe antchito, komanso moyo wautali pamagwiritsidwe ntchito pomwe matope wamba amatha kugwa. Kaya mukupanga, kumanga, kapena kukonza nyumba ya DIY, kumvetsetsa ntchito ndi ubwino wa dongo ladongo refractory kumatha kusintha mapulojekiti anu otentha kwambiri.
Choyamba, ng'anjo za mafakitale ndi ng'anjo ndi malo ochitira masewera olimbitsa thupi. M'mafakitale azitsulo, m'mafakitale agalasi, m'mafakitale a simenti, ndi malo opangira zida za ceramic, ng'anjo zimagwira ntchito pa kutentha kopitilira 1,000 ° C (1,832 ° F) kwa maola kapena masiku kumapeto. Mtondo wamba wa simenti wa Portland umasungunuka kapena kuwola mopitilira muyeso, zomwe zimapangitsa kulephera kwadongosolo, kutayikira, komanso kutsika mtengo. Dongo ladongo la refractory, komabe, limapangidwa ndi dongo loyera kwambiri, silica, ndi zophatikiza zina zomwe zimasunga mphamvu ndi mawonekedwe awo pakutentha kwambiri. Imasindikiza mipata pakati pa njerwa zomangira, kuteteza kutaya kutentha komwe kumatha kuchepetsa mphamvu zamagetsi mpaka 30%. Kwa ogwira ntchito m'mafakitale, izi zikutanthawuza kutsitsa mabilu amagetsi, kusokoneza pang'ono pokonza, komanso kutsata mfundo zotetezedwa.
Kuwonjezera pa mafakitale olemera, dongo ladongo la refractory ndilofunika kwambiri pamakina ogulitsa ndi nyumba. Poyatsira moto, mbaula za nkhuni, ndi zomangira za chumney zimadalira pazimenezi kuti zikhale zotchingira zotetezeka, zosamva kutentha. Tangoganizirani kuyatsa moto wokoma m'chipinda chanu chochezera kuti matope atseke njerwa ndi kutulutsa utsi wapoizoni - uku ndi chiopsezo chogwiritsa ntchito matope osakanizika. Dongo ladongo silimapirira kokha kutenthedwa ndi kuzizira kobwerezabwereza kwa m'nyumba zoyatsira moto komanso limalimbana ndi zowonongeka za nkhuni kapena malasha. Ndiosavuta kusakaniza ndikugwiritsa ntchito, ndikupangitsa kukhala chisankho chabwino kwambiri kwa akatswiri odziwa zomangamanga komanso okonda DIY chimodzimodzi. Eni nyumba omwe amaikapo poyatsira moto watsopano kapena kukonzanso yakale awona kuti kugwiritsa ntchito dongo ladongo refractory kumawonetsetsa kuti kutentha kwawo kumakhala kwazaka zambiri popanda kuwononga chitetezo.
Ntchito ina yofunika kwambiri ndi petrochemical ndi metallurgical process. Malo oyeretsera, osungunula, ndi opangira maziko amalimbana ndi kutentha kwambiri komanso mankhwala oopsa—asidi, alkali, ndi zitsulo zosungunuka zimene zingawononge matope wamba. Clay refractory mortar's chemical inertness imapangitsa kuti ikhale yabwino kwa ziwiya zomangira ziwiya, ma crucibles, ndi makina otulutsa mpweya. Zimapanga chisindikizo cholimba chomwe chimalepheretsa kutuluka kwa zinthu zoopsa, kuteteza ogwira ntchito ndi chilengedwe. Mwachitsanzo, posungunula aluminiyamu, dongo losungunula dongo limagwiritsidwa ntchito popanga maselo a electrolytic, pomwe amakana dzimbiri kuchokera ku chitsulo chosungunuka cha aluminiyamu ndi mchere wa fluoride. Kudalirika kumeneku ndi chifukwa chake ndi chisankho chomwe chimakondedwa m'mafakitale omwe ngakhale kulephera kochepa kwambiri kumatha kukhala ndi zotsatira zowopsa.
Clay refractory mortar amagwiranso ntchito yofunika kwambiri mu uvuni wa pizza ndi m'khitchini yamalonda. Mavuni a pizza opangidwa ndi nkhuni amagwira ntchito pa kutentha kwapakati pa 400 ° C ndi 500 ° C (752 ° F ndi 932 ° F), zomwe zimafuna matope omwe amatha kutentha kwambiri popanda kusweka kapena kutayika. Akatswiri ophika pizzeria komanso ophika kunyumba amakhulupiriranso dongo ladongo kuti lipange ndi kukonza mavuvuniwa, chifukwa limatsimikizira kufalikira kwa kutentha komanso kupewa utsi kapena kutentha kutha. M'makhitchini amalonda, amagwiritsidwa ntchito kuyika ma grill, ma rotisseries, ndi zida zina zotentha kwambiri, kusunga miyezo yaukhondo poletsa kuti tinthu tating'ono ting'onoting'ono titseke mumatope osweka.
Kodi ndi chiyani chomwe chimasiyanitsa matope a dongo ndi zinthu zina zomangira? Kusinthasintha kwake komanso kutsika mtengo. Mosiyana ndi matope a alumina kapena matope a silika, omwe amapangidwa kuti azitentha kwambiri koma amabwera ndi mtengo wamtengo wapatali, dongo ladongo refractory matope oyendetsa ntchito komanso kukwanitsa ntchito zambiri zotentha kwambiri. Imapezeka mu mawonekedwe a ufa, omwe amatha kusakanikirana ndi madzi pamalopo kuti agwirizane, kuchepetsa zinyalala komanso ndalama zoyendera. Kuonjezera apo, ili ndi ntchito yabwino kwambiri - omanga nyumba amatha kuumba mosavuta ndikuwongolera, kuonetsetsa kuti pali mgwirizano wolimba pakati pa njerwa.
Kusankha dongo loyenera ladongo ndikofunikira kuti polojekiti yanu ikhale yabwino. Yang'anani zinthu zomwe zimakwaniritsa miyezo yamakampani, monga ASTM C199, yomwe imatchula zofunikira pamatope okana. Ganizirani za kutentha kwakukulu kwa ntchito yanu, monga matope ena adongo amapangidwa kuti azitentha kwambiri kuposa ena. Pazinthu zamafakitale, sankhani matope okhala ndi zowonjezera zomwe zimakulitsa kulimba kwa kutentha komanso kukhazikika kwamankhwala. Kuti mugwiritse ntchito m'nyumba, dothi lokhazikika ladongo lidzakwanira poyatsira moto ndi masitovu ambiri.
Pomaliza, dongo la refractory matope ndi chinthu chofunikira kwambiri pakugwiritsa ntchito kulikonse komwe kumakhudza kutentha kwambiri. Kuchokera ku ng'anjo zamafakitale kupita kumalo oyatsira moto kunyumba, imapereka mphamvu, kukana kutentha, komanso kulimba kofunikira kuti nyumbayo ikhale yotetezeka komanso yogwira ntchito bwino. Kugwiritsa ntchito kwake kosiyanasiyana, kutsika mtengo, komanso kugwiritsa ntchito mosavuta kumapangitsa kukhala chisankho chabwino kwambiri kwa akatswiri ndi ma DIYers m'mafakitale onse. Ngati mukukonzekera pulojekiti yotentha kwambiri, musagwirizane ndi matope wamba - sungani matope a dongo ndikuonetsetsa kuti ntchito yanu ikuyesa nthawi.
