Kana zvasvika kune nzvimbo dzekupisa kwepamusoro-kubva kuchoto dzemaindasitiri kuenda kunzvimbo dzekugara-chinhu chimwe chinomira pachena semusana wekuvimbika kwechimiro:ivhu refractory dhaka. Yakagadzirwa kuti ishingirire kupisa kwakanyanya, kukukurwa kwemakemikari, uye kuvhundutsa kwemafuta, dhaka remhando iyi rinopfuura “namo” chete pazvidhinha zvinorasa. Icho chinhu chakakosha chinovimbisa kuchengetedza, kushanda zvakanaka, uye hupenyu hurefu mumashandisirwo apo madhaka akajairwa anoputsika. Kunyangwe iwe uri mukugadzira, kuvaka, kana DIY kuvandudza imba, kunzwisisa mashandisirwo uye mabhenefiti evhu refractory dhaka kunogona kushandura mapurojekiti ako ekupisa kwepamusoro.
Chekutanga uye chakakosha, mavira emaindasitiri uye honi ndiyo nzvimbo yekutanga yekutamba yevhu refractory dhaka. Muzvigayo zvesimbi, mafekitori egirazi, zvidyarwa zvesimende, uye zvivakwa zvekugadzira zveceramic, hove dzinoshanda patembiricha inopfuura 1,000°C (1,832°F) kwemaawa kana mazuva apera. Zvakajairwa Portland simende dhaka inonyunguduka kana kuora pakunyanyisa kwakadaro, zvichitungamira mukutadza kwechimiro, kudonha, uye kudhura kuderera. Clay refractory dhaka, zvisinei, inoumbwa nevhu-kuchena kwevhu, silica, uye zvimwe zvinoramba zvakaunganidzwa zvinochengeta chisungo chesimba uye chimiro pane izvi zvakanyanya tembiricha. Inovhara mapeji pakati pezvidhinha zvinoramba, kudzivirira kurasikirwa kwekupisa kunogona kuderedza kushanda kwesimba kusvika ku30%. Kune vanoita zvemaindasitiri, izvi zvinoturikira kudzikisira mabhiri emagetsi, kushomeka kwekukanganisa kwekugadzirisa, uye kutevedzera kuchengetedzwa kwakasimba.
Kupfuura indasitiri inorema, ivhu refractory dhaka chinhu chikuru mune zvekutengesa uye zvekugara masisitimu ekudziya. Zvitofu, zvitofu zvehuni, uye marambi echimney zvinotsamira pazviri kugadzira chinodzivirira, chinodzivirira kupisa. Fungidzira kubatidza moto unotonhorera muimba yako yekutandarira chete kuti dhaka rakabata zvidhinha zvako zvepachoto pamwe chete kutsemuka uye kuburitsa utsi hune muchetura — iyi ndiyo njodzi yekushandisa dhaka risingarambiki. Clay refractory mortar haingomirire chete kudzokororwa kwekudziya uye kutonhora kwenzvimbo dzekugara asiwo inodzivirira zvinopisa zvinobuda zvehuni kana marasha. Zviri nyore kusanganisa uye kushandisa, zvichiita kuti ive sarudzo yepamusoro kune nyanzvi masons uye DIY vanofarira zvakafanana. Varidzi vemba vanoisa mari munzvimbo itsva yemoto kana kugadziridza yekare vanozoona kuti kushandisa ivhu refractory dhaka kunoita kuti kupisa kwavo kunogara kwemakumi emakore pasina kukanganisa kuchengetedza.
Imwe yakakosha application ndeye petrochemical uye metallurgical process. Michina inocheneswa, inonyungudutsa, uye midziyo inonyungudutswa haingobatanidzi tembiricha yakakwira chete asiwo makemikari ane hasha—asidhi, alkali, uye simbi yakanyungudutswa inogona kuparadza dhaka remazuva ose. Clay refractory mortar's kemikari inertness inoita kuti ive yakakodzera kune lining reaction midziyo, macrucibles, uye exhaust masisitimu. Inoumba chisimbiso chakasimba chinodzivirira kubuda kwezvinhu zvine ngozi, kuchengetedza vashandi uye nharaunda. Mukunyungudusa aruminiyamu, semuenzaniso, ivhu refractory dhaka rinoshandiswa kumisa masero e electrolytic, kwaanoramba kukora kubva kunyungudutswa aluminiyamu uye fluoride munyu. Kuvimbika uku ndosaka iriyo sarudzo inosarudzika mumaindasitiri umo kunyangwe kutadza kudiki kunogona kuve nemhedzisiro yakaipa.
Clay refractory mortar inoitawo basa rakakosha mumahovhoni epizza uye makicheni ekutengesa. Mahovhoni epizza anopiswa nehuni anoshanda patembiricha iri pakati pe400°C ne500°C (752°F ne932°F), ichida dhaka rinokwanisa kubata kupisa kwakanyanya pasina kutsemuka kana kurasikirwa nekunamira. Nyanzvi dzepizzerias nevabiki vekumba zvakafanana vanovimba nevhu refractory dhaka kuvaka nekugadzirisa maovheni aya, sezvo ichiva nechokwadi chekugovera kupisa kwakafanana uye kudzivirira utsi kana kupisa kubva. Mumakicheni ekutengesa, anoshandiswa kumisa magrill, rotisseries, uye zvimwe zvinopisa-kupisa midziyo, kuchengetedza hutsanana nekudzivirira zvimedu zvekudya kuti zvisabatwe mudhaka rakatsemuka.
Chii chinosiyanisa ivhu refractory dhaka kubva kune zvimwe zvinhu zvinoramba? Kuchinja-chinja kwaro uye mari-inoshanda. Kusiyana ne-high-alumina kana silica mortar, iyo yakagadzirirwa kutonhora kwepamusoro-soro asi ichiuya nemutengo wepamusoro, ivhu refractory mortar zviyero kushanda uye kukwanisa kwezvinowanzozivikanwa zvekushisa kwepamusoro. Inowanikwa muhupfu, iyo inogona kusanganiswa nemvura pa-saiti kune inodiwa kuenderana, kuderedza marara uye mari yekufambisa. Pamusoro pezvo, ine hunyanzvi hwekushanda-masoni anogona kuumba nyore uye kutsetseka, kuve nechokwadi chekubatana kwakasimba pakati pezvidhinha.
Kusarudza ivhu rakakodzera refractory mortar kwakakosha kuti chirongwa chako chibudirire. Tarisa zvigadzirwa zvinosangana neindasitiri zviyero, seASTM C199, iyo inotsanangura zvinodikanwa zverefractory dhaka. Funga nezve tembiricha yepamusoro yechishandiso chako, sezvo mamwe madhaka evhu anogadzirwa kuti awedzere kupisa kupfuura mamwe. Kune mapurojekiti emaindasitiri, sarudza dhaka rine zvinowedzerwa izvo zvinosimudzira kupisa kwekuvhunduka uye kugadzikana kwemakemikari. Pakushandisa pekugara, dhaka refractory dhaka rakajairwa rinokwana nzvimbo zhinji dzemoto uye zvitofu.
Mukupedzisa, ivhu refractory dhaka chinhu chakakosha mune chero application inosanganisira kupisa kwakanyanya. Kubva pachoto cheindasitiri kuenda kudzimba dzemoto, inopa simba, kudzivirira kupisa, uye kusimba kunodiwa kuchengetedza zvivakwa zvakachengeteka uye zvakanaka. Hwaro hwakasiyana hwekushandisa, mutengo-unoshanda, uye nyore kushandisa kunoita kuti ive sarudzo yepamusoro kune nyanzvi uye maDIYers mumaindasitiri ese. Kana uri kuronga purojekiti yepamusoro-soro, usagadzirisa dhaka rakajairika-isa mari muvhu refractory mortar uye uone kuti basa rako rinomira nguva.
