Ntchito yomanga ma castables osamva kutentha kwambiri imachitika ndi njira yogwedera, yomwe imagwiritsidwa ntchito kwambiri, kuphatikiza kupanga zida zowuma zowuma.Kodi mukudziwa njira yolondola yogwiritsira ntchito zotayira zosagwira kutentha kwambiri?
1. Kukonzekera musanamangidwe
Malingana ndi zofunikira za mapangidwe apangidwe, khalidwe la zomangamanga la ndondomeko yapitayi lidzayang'aniridwa ndikuvomerezedwa, ndipo malo opangira boiler adzayeretsedwa.
Chosakaniza chokakamizika, plug-in vibrator, ngolo yamanja ndi makina ena ndi zida zimatumizidwa kumalo opangira boiler, omwe amaikidwa m'malo mwake, ndipo kuyesa kuyesa ndikwachilendo.Gome lotsatirali likuwonetsa zizindikiro zaukadaulo za plug-in vibrator.Ndikoyenera kunena kuti ndodo yogwedezeka yokakamiza yomwe imagwiritsidwa ntchito posakaniza iyenera kukhala yafupipafupi ndipo payenera kukhala ndi zida zokwanira.
Mafomuwa adzakhala ndi mphamvu zokwanira komanso zolimba, ngakhale zitatumizidwa kumalo opangira moto;Mphamvu yowunikira imalumikizidwa, ndipo madzi oyera amalumikizidwa kutsogolo kwa chosakaniza.
Zosatha kutentha kwambiri zimayikidwa m'matumba.Zida monga njerwa za nangula, zolumikizira, njerwa zotsekereza zotsekereza, matabwa a silicate a calcium, matabwa a asbesitosi, njerwa zadongo zomangira ndi njerwa zoyatsira zimayenera kutengedwa kupita kumalo opangirako nthawi iliyonse yomwe ikufunika.
Akagwiritsidwa ntchito, ndende yake kapena kachulukidwe kake kamayenera kusinthidwa pasadakhale ndikutumizidwa kumalo opangira boiler kuti agwiritsidwe ntchito.Musanagwiritse ntchito, idzagwedezeka mofanana kachiwiri.
2. Kutsimikizika kwa gawo losakanikirana la zomangamanga
Asanamangidwe, ma castables omwe amanyamula kutentha kwambiri komanso zowonjezera zawo adzayesedwa ndi kuyesedwa malinga ndi zofunikira za zojambulazo kapena malangizo a wopanga, ndipo katundu wamkulu adzayang'aniridwa.Pamene mkulu kutentha kugonjetsedwa castable akulephera kukwaniritsa kapangidwe amafuna, zinthu adzakhala m'malo mwamsanga momwe angathere popanda kusasamala.Choncho, ntchito imeneyi ndi yofunika kwambiri.Popeza kugula kwapamwamba kutentha kugonjetsedwa castables, chidwi ayenera kulipidwa zizindikiro zawo ntchito.Zogulitsa zoyenerera zidzagwiritsidwa ntchito ngati gawo losakanikirana la zomangamanga za malo opangira boiler malinga ndi momwe malo opangira boiler amakhalira komanso nthawi yosungiramo zinthuzo.
3. Kuyala ndi formwork wa matenthedwe kutchinjiriza wosanjikiza
Pomanga kugwedera kwa ma castables osamva kutentha kwambiri, ntchitoyi ndi ya kukonzekera komanga.
Pamaso pomanga mkulu kutentha kugonjetsedwa castable ng'anjo khoma, choyamba anagona asibesitosi bolodi, kashiamu silicate bolodi kapena CHIKWANGWANI refractory anamva, kukhazikitsa zitsulo zolumikizira, ikani nangula njerwa, ndipo kachiwiri anagona insulatory refractory njerwa kapena kutsanulira kuwala kutentha kugonjetsedwa castables;Chachitatu ndi kukhazikitsa formwork.Malo ogwirira ntchito a formwork ayenera yokutidwa ndi mafuta kapena zomata poyamba, ndiyeno pafupi ndi mapeto a ntchito ya njerwa ya nangula kuti athandizidwe.Kutalika kwa formwork anamanga nthawi iliyonse ndi 600 ~ 1000mm, kuti atsogolere Mumakonda ndi kugwedera akamaumba.Pankhani ya nembanemba ya fetal, nembanemba ya fetal iyenera kuthandizidwa koyamba, kenako mawonekedwe ake amamangidwa.Pamwamba pazitsulo zotsekemera zotentha ziyenera kupakidwa ndi filimu ya pulasitiki kuti zisatenge madzi ndi kusokoneza ntchito ya castable.
Khoma la ng'anjo likakhala lalitali, nsonga yotsekerayo iyeneranso kumangidwa m'magawo kuti muteteze kutsanuliridwa kwa wosanjikiza wa ng'anjo pamene zinthu zothirira zimagwedezeka.
Pakumanga ng'anjo yowotchera ng'anjo yowongoka, mawonekedwe onsewo akhazikitsidwe mwamphamvu kenako ndikuthiridwa mafuta molingana ndi kapangidwe kake;Kenako pangani njerwa zopachikidwa pamtengo wokweza ndi zolumikizira zitsulo.Zolumikizira zina zimafunikira kukhazikitsidwa ndi ma wedges amatabwa, pomwe zina siziyenera kukhazikitsidwa.Njerwa zolendewera ziziyikidwa molunjika ndi ng'anjo yogwira ntchito.Mtunda pakati pa pansi kumapeto kwa nkhope ndi mawonekedwe a formwork ndi 0 ~ 10mm, ndipo kumapeto kwa njerwa zopachikidwa zokhala ndi mfundo zopitilira 60% ziyenera kulumikizana ndi nkhope ya formwork.Pamene matayala ndi aakulu kuposa 10mm, zolumikizira zitsulo ziyenera kusinthidwa kuti zikwaniritse zofunikira.Pakakhala mabowo, nembanembayo iyeneranso kukhazikitsidwa molimba, kenako mawonekedwewo adzakhazikitsidwa.
4. Kusakaniza
Chosakaniza chokakamiza chidzagwiritsidwa ntchito kusakaniza.Pamene kuchuluka kwa zinthu kumakhala kochepa, kungathenso kusakaniza pamanja.Kusakanikirana kwa ma castables osagwirizana ndi kutentha kumakhala kosiyana chifukwa cha mitundu yosiyanasiyana;Pakukweza thumba kapena kuphatikizika kwa simenti ndi simenti, cholakwika chovomerezeka ndi ± 1.0 peresenti, cholakwika chovomerezeka pazowonjezera ndi ± 0.5 peresenti, cholakwika chovomerezeka cha hydrated liquid binder ndi ± 0.5 peresenti, ndipo mlingo wa zowonjezera uyenera kukhala wolondola. ;Mitundu yonse ya zipangizo ziyenera kutsanuliridwa mu chosakanizira pambuyo polemera popanda kusiya kapena kuwonjezera.
Pakuti kusakaniza kutentha kugonjetsedwa castables monga simenti, dongo kugwirizana ndi otsika simenti mndandanda, choyamba kutsanulira thumba Mumakonda, zina ndi zina mu chosakanizira kupanga zinthu zambiri, ndiyeno youma kusakaniza iwo 1.0min, ndiyeno kuwonjezera madzi yonyowa kuwasakaniza kwa 3-5 min atatha kukhala yunifolomu.Kutulutsa iwo pambuyo mtundu wa zipangizo ndi yunifolomu.Kenako amatumizidwa ku kanjedza ndipo nsalu imayambika.
Pakuti kusakaniza wa sodium silicate mkulu-kutentha kugonjetsedwa castable, zopangira kapena granules akhoza kuikidwa mu chosakanizira youma kusanganikirana, ndiyeno sodium silicate njira anawonjezera kuti chonyowa kusanganikirana.Pambuyo pa granules atakulungidwa ndi sodium silicate, ufa wotsutsa ndi zipangizo zina zimawonjezeredwa.Kusakaniza konyowa kumakhala pafupifupi 5min, ndiyeno zipangizo zimatha kutulutsidwa kuti zigwiritsidwe ntchito;Ngati zouma zowuma zimasakanizidwa, zitsanulirani mu chosakanizira chowuma kusakaniza kwa 1.0min, onjezerani 2/3 sodium silicate yankho la kusakaniza konyowa kwa 2-3min, ndikuwonjezera otsala omangiriza kusakaniza konyowa kwa 2-3min, ndiye. zipangizo zingagwiritsidwe ntchito.Kusakaniza kwa utomoni ndi kaboni wokhala ndi kutentha kosasunthika kwambiri ndikofanana ndi izi.
Posakaniza zotayira zosamva kutentha kwambiri monga phosphoric acid ndi phosphate, choyamba tsanulirani zouma zouma mu chosakanizira kuti musakanize zowuma kwa 1.0min, onjezerani pafupifupi 3/5 ya zomangira zosakaniza zonyowa kwa mphindi 2-3, kenako tulutsani zinthuzo. , nyamulani kupita kumalo opangira stacking, kuphimba mwamphamvu ndi filimu ya pulasitiki, ndipo tcherani zinthuzo kwa nthawi yoposa 16h.Zida zotsekeredwa ndi coagulant accelerator ziyenera kuyezedwa ndikutsanuliridwa mu chosakanizira chachiwiri kusakaniza, ndi binder yotsalayo idzawonjezedwa kwa kusakaniza konyowa kwa 2-4min musanagwiritse ntchito.
Pa kusakaniza kwapamwamba kutentha kugonjetsedwa ndi castables, ngati zowonjezera monga kutentha zosagwira zitsulo CHIKWANGWANI, moto zosagwira CHIKWANGWANI ndi organic CHIKWANGWANI ayenera kuwonjezeredwa ku castables, ayenera mosalekeza kumwazikana mu kusakaniza zipangizo chosakanizira pa chonyowa kusakaniza castables. .Ayenera kumwazikana ndi kusakaniza nthawi imodzi, ndipo sayenera kuikidwa mu chosakaniza m'magulu.
Kusakaniza kumatulutsidwa kuchokera ku chosakaniza, ngati chouma kwambiri, chowonda kwambiri kapena chopanda zinthu zina, zinthuzo zidzatayidwa ndipo sizidzawonjezedwanso;Kusakaniza kotulutsidwa kuchokera ku chosakanizira kumakhala mkati mwa 0.5 ~ 1.0h.
