Ukwakhiwa kwe-castables ukumelana nokushisa okuphezulu kwenziwa ngendlela yokudlidliza, esetshenziswa kabanzi, kuhlanganise nokwakhiwa kwezinto ezomile zokudlidliza.Ingabe uyayazi indlela elungile yokusebenzisa ama-castable amelana nokushisa okuphezulu?
1. Ukulungiselela ngaphambi kokwakhiwa
Ngokwezidingo zobukhulu bokuklama, ikhwalithi yokwakha yenqubo yangaphambilini izohlolwa futhi yamukelwe, futhi indawo yokwakha ibhayela izohlanzwa.
I-mixer ephoqiwe, i-plug-in vibrator, inqola yesandla kanye neminye imishini namathuluzi kuhanjiswa endaweni yokwakhiwa kwamabhayela, afakwe endaweni, futhi ukuhlolwa kokuhlola kujwayelekile.Ithebula elilandelayo libonisa izinkomba zobuchwepheshe ze-plug-in vibrator.Kufanele kuphawulwe ukuthi induku yokudlidliza ephoqelelwe esetshenziselwa ukuxuba kufanele ibe nemvamisa ephezulu futhi kube nezingxenye ezisele ezanele.
I-formwork izoba namandla anele kanye nokuqina, noma ngabe ithuthelwa endaweni yokwakha ibhayela;Amandla okukhanyisa axhunyiwe, futhi amanzi ahlanzekile axhunywe ngaphambili kwe-mixer.
Ama-castable ukumelana nokushisa okuphezulu ngokuvamile apakishwa ezikhwameni.Izinto ezifana nezitini zehange, izixhumi, izitini ze-insulactory, amabhodi e-calcium silicate, amabhodi e-asbestos, izitini zobumba eziphikisayo nezitini zokushisa kufanele zihanjiswe endaweni yokwakha kubhayela nganoma yisiphi isikhathi njengoba kudingekile.
Lapho kusetshenziswa i-ejenti ebophezela amakhemikhali, ukugxilwa kwayo noma ukuminyana kwayo kuzolungiswa kusenesikhathi futhi ithuthelwe endaweni yokwakha ubhayela ukuze isetshenziswe.Ngaphambi kokusetshenziswa, kufanele ixutshwe ngokulinganayo futhi.
2. Ukuqinisekiswa kwesilinganiso sokuxuba ukwakhiwa
Ngaphambi kokwakhiwa, ama-castable amelana nokushisa okuphezulu anezikhwama kanye nezithasiselo zawo kufanele athathwe futhi ahlolwe ngokuvumelana nezidingo zemidwebo yokuklama noma imiyalelo yomkhiqizi, futhi izakhiwo eziyinhloko zizohlolwa.Lapho okuphonswayo ukumelana nezinga lokushisa eliphezulu kwehluleka ukuhlangabezana nezidingo zedizayini, okokusebenza kuzoshintshwa ngokushesha ngangokunokwenzeka ngaphandle kokunganaki.Ngakho-ke, lo msebenzi ubaluleke kakhulu.Njengoba ukuthengwa kwama-castables ukumelana nokushisa okuphezulu, ukunakwa kufanele kukhokhwe ezinkomba zabo zokusebenza.Imikhiqizo efanelekile izosetshenziswa njengengxenye yokuxuba ukwakhiwa kwesizinda sokwakha ubhayela ngokuya ngemibandela yendawo yokwakha ubhayela kanye nesikhathi sokugcina sezinto.
3. Ukubeka kanye nesakhiwo se-thermal insulation layer
Ukuze ukwakhiwa kokudlidliza kwama-castable ukumelana nokushisa okuphezulu, lo msebenzi futhi ungowokulungiselela ukwakhiwa.
Ngaphambi kokwakhiwa kodonga lwesithando somlilo ongamelana nokushisa okuphezulu, okokuqala beka ibhodi le-asbestos, ibhodi le-silicate ye-calcium noma i-fiber refractory wazizwa, faka izixhumi zensimbi, ubeke izitini zehange, futhi okwesibili ubeke izitini eziphikisayo ezivimbelayo noma uthele ukukhanya okuqinile ukumelana nokushisa okuphezulu;Okwesithathu ukumisa i-formwork.Indawo yokusebenza ye-formwork kufanele igcotshwe ngamafutha noma izitikha kuqala, bese isondela eduze kobuso bokuphela kwesitini sehange ukuze kusekelwe.Ukuphakama kwe-formwork eyakhiwe isikhathi ngasinye ingu-600 ~ 1000mm, ukuze kube lula ukulayisha nokubunjwa kokudlidliza.Endabeni yolwelwesi lwe-fetus, ulwelwesi lwe-fetus luzosekelwa kuqala, bese kumiswa umsebenzi wesakhiwo.Ingaphezulu lesendlalelo se-thermal insulation kufanele ligandaywe ngefilimu yepulasitiki ukuze livinjwe limunce amanzi futhi lithinte ukusebenza kwe-castable.
Uma udonga lwesithando somlilo luphakeme, ungqimba lokufakelwa kufanele lwakhiwe futhi lube yizingqimba ukuze kuvinjelwe ukuthululwa kwesendlalelo sokushisa lapho okuthululwayo kudlidliza.
Ngesikhathi sokwakhiwa kwesithando somlilo esivuthayo esiphikisayo, yonke i-formwork izokwakhiwa iqine bese igcotshwa ngokuhambisana nezidingo zobukhulu bomklamo;Bese ulenga izitini ezilenga emgqeni ophakamisayo ngezixhumi zensimbi.Ezinye izixhumi zidinga ukulungiswa ngama-wedges okhuni, kanti ezinye azidingi ukulungiswa.Izitini ezilengayo kufanele zibekwe zibheke phezulu kanye nohlaka lwesithando somlilo.Ibanga phakathi kobuso obuphansi kanye nobuso be-formwork ngu-0 ~ 10mm, futhi ubuso bokugcina bezitini ezilengayo ezinamaphoyinti angaphezu kwamaphesenti angu-60 buzothinta ubuso be-formwork.Uma isikhala singaphezu kuka-10mm, izixhumi zensimbi kufanele zilungiswe ukuze zihlangabezane nezidingo.Uma kunezimbobo, ulwelwesi luzophinde lufakwe ngokuqinile, bese kwakhiwa umsebenzi wefomu.
4. Ukuxuba
I-mixer eyimpoqo izosetshenziselwa ukuxuba.Uma inani lempahla lincane, lingabuye lixutshwe ngesandla.Ukuxuba ama-castable ukumelana nokushisa okuphezulu kuhlukile ngenxa yezinhlobonhlobo ezahlukene;Ekulayishweni kwezikhwama noma isamba se-refractory kanye nosimende, iphutha elivumelekile lingamaphesenti angu-± 1.0 amaphuzu, iphutha elivumelekile lezithasiselo lingamaphesenti angu-± 0.5 amaphuzu, iphutha elivumelekile le-hydrated liquid binder ngamaphesenti angu-± 0.5 amaphuzu, futhi umthamo wezithako kufanele ube nembe ;Zonke izinhlobo zezinto zokusetshenziswa kufanele zithelwe ku-mixer ngemva kokukala ngaphandle kokushiya noma ukwengeza.
Ukuze kuxutshwe izinto ezikwazi ukumelana nokushisa okuphezulu okufana nosimende, isibopho sobumba nochungechunge oluphansi lukasimende, qala uthele isikhwama esilayishwayo, izithasiselo nezithasiselo ku-mixer ukuze wenze izinto eziningi, bese uxuba ezomile i-1.0min, bese wengeza amanzi zixube ezimanzi imizuzu engu-3-5 ngemva kokuba zifana nomfaniswano.Zikhiphe ngemuva kokuthi umbala wezinto ufana nomfaniswano.Bese ithuthelwa entendeni bese kuqalwa indwangu.
Ukuze kuhlanganiswe i-sodium silicate high-temperature resistant castable, izinto ezingavuthiwe noma ama-granules angafakwa ku-mixer ukuze kuxutshwe okomile, bese isixazululo se-sodium silicate sengezwa ukuxuba okumanzi.Ngemuva kokuthi ama-granules ehlanganiswe ne-sodium silicate, i-powder refractory nezinye izinto zengezwa.Ukuxuba okumanzi cishe ku-5min, bese izinto zingase zikhishwe ukuze zisetshenziswe;Uma izinto ezomile zixutshwe ndawonye, zithele ku-mixer yokuxuba okomile kwe-1.0min, engeza isisombululo se-2/3 se-sodium silicate sokuxuba okumanzi kwe-2-3min, bese wengeza i-ejenti yokubopha esele yokuxuba okumanzi kwe-2-3min, bese izinto zokwakha zingasetshenziswa.Ukuxutshwa kwe-resin ne-carbon equkethe izinga lokushisa eliphezulu elikwazi ukuphonswa kuyafana nalokhu.
Ukuze kuxutshwe izinto ezisindayo ezimelana nokushisa okuphezulu okufana ne-phosphoric acid ne-phosphate, qala ngokuthela okomile okomile ku-mixer ukuze kuxutshwe okomile i-1.0min, engeza cishe u-3/5 we-binder ukuze kuxutshwe okumanzi imizuzu engu-2-3, bese ukhipha okokusebenza. , uyihambise endaweni eklanyelwe ukupakishwa, uyimboze ngokuqinile ngefilimu yepulasitiki, bese ubamba impahla isikhathi esingaphezu kwe-16h.Izinto eziboshiwe kanye ne-accelerator ye-coagulant kufanele zikalwe futhi zithelwe ku-mixer ukuze kuhlanganiswe okwesibili, futhi i-binder esele izongezwa ukuxuba okumanzi 2-4min ngaphambi kokusetshenziswa.
Ngesikhathi sokuxutshwa kwezinsimbi ezikwazi ukumelana nokushisa okuphezulu, uma izithasiselo ezifana ne-fiber yensimbi engashi, i-fiber engashi kanye ne-organic fiber kudingeka kwengezwe ezintweni eziphonswayo, kufanele zihlakazeke ngokuqhubekayo ezintweni zokuxuba ze-mixer ngesikhathi sokuxutshwa okumanzi kwama-castable. .Kufanele zihlakazwe futhi zixutshwe ngesikhathi esifanayo, futhi akufanele zifakwe ku-mixer ngamaqembu.
Ngemuva kokuthi ingxube ikhishwe ku-mixer, uma isomile kakhulu, incane kakhulu noma ingenayo into ethile, impahla izolahlwa futhi ngeke yengezwe futhi;Ingxube ekhishwe ku-mixer izoba phakathi kuka-0.5 ~ 1.0h.
