Kumanga kwa castable kumayang'ana maulalo angapo monga kuwotcherera pini, kupenta phula, kusakaniza madzi, kukonza nkhungu, kugwedezeka, kuteteza nkhungu kumasula, kutsimikizika kwa kukula, ndi kulondola kwa mfundo zoyezera, ndipo kukhazikitsidwa kumachitika mogwirizana ndi zofunikira za zinthuzo. wopanga ndi fakitale yowotchera.
1. Pini ndi litenge unsembe msomali
Asanayambe kupanikizika kwa madzi, zikhomo zomwe zili m'madera okhudzidwa monga kuwotcherera kwa malo otenthetsera kutentha ndi zophatikizana zowotcherera ndi zolumikizira zowotcherera pamoto panthawi yoyendetsa ndi kukhazikitsa ziyenera kudzazidwa. Konzani kuwotcherera ndi kugwira misomali kuti muwonetsetse kuti zikhomozo zimakonzedwa molingana ndi kachulukidwe kopangidwa. Pamaso kuthira, ntchito wosanjikiza wa phula utoto ndi makulidwe> 1mm pa onse ophatikizidwa zitsulo mbali, misomali ndi zina zitsulo pamwamba kapena kukulunga zinthu zoyaka.
2. Zosakaniza, kugawa madzi, kusakaniza kulamulira
Zosakaniza zimayesedwa ndipo madzi amagawidwa motsatira zofunikira za bukhu lazinthu la wopanga zinthu, ndipo munthu wosankhidwa ali ndi udindo woyeza molondola. Madzi omwe amagwiritsidwa ntchito posakaniza zotayira ayenera kukhala madzi aukhondo (monga madzi akumwa), okhala ndi pH ya 6 ~ 8. Samalani dongosolo la kuwonjezera madzi ndi nthawi yosakaniza ndi kusakaniza. Sichiloledwa kuwonjezera madzi mwakufuna kwake, ndipo sikuloledwa kupititsa patsogolo kapena kuwonjezera nthawi yosakaniza mosasamala. Kuchuluka kwa madzi sayenera kuwonjezeredwa pa malo amodzi, ndipo zotayira ziyenera kusakanikirana. M`pofunika kuwonjezera zitsulo CHIKWANGWANI kuti castable pa ndondomeko kuwonjezera madzi ndi kusanganikirana, ndipo sadzakhala wothira mu agglomerates.
3.Template control
Kupanga nkhungu yotayidwa ndi njira yovuta kwambiri, ndipo mtundu wa nkhungu umakhudza mwachindunji mtundu wa oponyedwa. Ulamuliro wa template umayang'ana kwambiri kuvomereza kulimba kwake komanso kulondola kwazithunzi. Template iyenera kukhala yolimba komanso yolumikizidwa mwamphamvu kuti iwonetsetse kuti palibe kusuntha kapena kumasuka panthawi yothira. Chikombole chamatabwa chiyenera kuikidwa molingana ndi miyeso ya geometric ya zojambula zomanga ndi kutsanulira makulidwe, okonzedweratu ndi osonkhanitsidwa, ndipo mawonekedwe ake ndi olimba. Chikombolecho chimapangidwa ndi template ya 15 cm ndi bwalo lamatabwa, ndi m'lifupi mwake ≤500mm; nkhungu yooneka ngati yapadera imapangidwa ndi bwalo lamatabwa ndipo imakutidwa ndi bolodi Lopangidwa ndi masentimita atatu, pamwamba pake amatsukidwa ndi otulutsa awiri kuti atsimikizire kuti makulidwe a castable ndi pamwamba pambuyo pomanga ndi yosalala komanso yoyera popanda pitting. Fomuyi iyenera kufufuzidwa ndikuvomerezedwa isanamangidwe.
4.Kuthira kulamulira
Mukathira chowotchera, kutalika kwa chakudya chilichonse kumayendetsedwa mumtundu wa 200 ~ 300mm, gawo lomwe lili ndi makulidwe akulu kuposa 50mm limatsanuliridwa ndi kugwedezeka komwe kumayikidwa, ndipo njira ya "kufulumira komanso pang'onopang'ono" imagwiritsidwa ntchito kunjenjemera mosalekeza. Pakugwedezeka kuti muteteze kusungidwa Kwa dzenje lapansi ndi kugwedera kwamadzi, nthawi yogwedezeka ya mfundo iliyonse siyenera kukhala yayitali kwambiri kuti ufa wabwino usayandama. Panthawi yogwedezeka, ndodo yogwedezeka siyenera kugunda template ndi kukokera misomali kwambiri. Mukathira ma castables okulirapo kuposa 50mm, malo opitilira 10m2 ayenera kumangidwa pamalo awiri nthawi imodzi; kuonetsetsa kuti zipangizo osakanikirana amatsanuliridwa mkati mwa nthawi yotchulidwa, kuthira mbali zosakwana 50mm wandiweyani amakonda kukhala pawokha leveling ndi basi Degassed kudzikonda otaya castable yomanga.
5.Kusungirako zowonjezera zowonjezera
Chifukwa chakuti chiwongoladzanja chowonjezera chachitsulo sichikugwirizana ndi kukula kwachitsulo, ndi pafupifupi theka la chitsulocho. Kawirikawiri, pali njira zinayi zothetsera kukulitsa kwazitsulo: imodzi ndiyo kujambula utoto wa asphalt pa pini ndi zitsulo pamwamba, makulidwe si osachepera 1mm. Chachiwiri ndi gawo lalikulu la kutsanulira, lomwe limatsanuliridwa muzitsulo 800 ~ 1000 × 400 iliyonse, ndipo zowonjezera zowonjezera zimayikidwa pambali kuti zichoke pambali. Chachitatu ndi kupeta pepala la ceramic fiber ndi makulidwe a 2mm pamwamba pa hood, zopangira chitoliro cha zida, ndi magawo olowera mpanda wachitsulo monga zolumikizira zowonjezera. Chachinayi, mpeni ukhoza kugwiritsidwa ntchito kudula kusiyana kwa theka la makulidwe panthawi yomanga pulasitiki, kapena dzenje likhoza kuponyedwa mupulasitiki kuti athetse vuto la kukulitsa.
