A na-arụ nnukwu ihe nkedo na-eguzogide okpomọkụ dị elu site na usoro ịma jijiji, nke a na-ejikarị eme ihe, gụnyere ịmepụta ihe ọkụkụ akọrọ.Ị maara usoro eji ihe castables na-eguzogide okpomọkụ dị elu?
1. Nkwadebe tupu owuwu
Dị ka ihe ndị a chọrọ n'ichepụta ihe, a ga-enyocha mma ụlọ nke usoro gara aga ma nabata ya, a ga-ehichapụkwa ebe ọkụ ọkụ.
A na-ebufe igwekota mmanye, plug-in vibrator, ụgbọ aka na igwe na ngwaọrụ ndị ọzọ na ebe a na-ewu ọkụ ọkụ, tinye ya n'ebe, na ule ule bụ ihe nkịtị.Tebụl na-esonụ na-egosi ihe nrịbama teknụzụ nke plug-in vibrator.Ekwesịrị ịkọwapụta na mkpanaka mmanye amanye ejiri maka igwekota kwesịrị ịdị elu ugboro ugboro yana enwere akụkụ zuru oke.
Ụdị nhazi ahụ ga-enwe ike zuru oke na isi ike, ọ bụrụgodị na a na-ebuga ya na ebe a na-ewu ọkụ ọkụ;Ejikọtara ike ọkụ, na mmiri dị ọcha jikọtara n'ihu igwekota.
A na-achịkọta castables nke na-eguzogide okpomọkụ dị elu n'ime akpa.Ihe ndị dị ka brik arịlịka, njikọ njikọ, brik ndị na-ekpuchi ọkụ, mbadamba calcium silicate, mbadamba asbestos, brik ụrọ na-agbagharị agbagharị na brik ọkụ ga-ebuga n'ebe a na-arụ ọkụ ọkụ n'oge ọ bụla dị ka achọrọ.
Mgbe a na-eji ihe na-ejikọta kemịkal, a ga-edozi njupụta ya ma ọ bụ njupụta ya n'ihu ma buru ya gaa n'ebe a na-ewu ọkụ ọkụ maka ojiji.Tupu eji ya eme ihe, a ga-emegharị ya nke ọma ọzọ.
2. Nkwenye nke ngwakọta ihe owuwu ụlọ
Tupu e wuo ya, a ga-enyocha ihe castables na ihe mgbakwunye ha dị elu ma nwalee dịka ihe achọrọ nke eserese ma ọ bụ ntuziaka onye nrụpụta si dị, a ga-enyocha ihe ndị bụ isi.Mgbe castable na-eguzogide okpomọkụ dị elu na-emezughị ihe a chọrọ, a ga-edochi ihe ahụ ozugbo enwere ike na-enweghị nlezianya.Ya mere, ọrụ a dị ezigbo mkpa.Ebe ọ bụ na ịzụrụ ihe castables na-eguzogide okpomọkụ dị elu, ekwesịrị ịṅa ntị na ihe ngosi arụmọrụ ha.A ga-eji ngwaahịa ndị tozuru oke mee ihe dị ka ngwakọta ihe owuwu nke ebe a na-ewu ihe ọkụkụ dị ka ọnọdụ nke ebe a na-esi ọkụ ọkụ na oge nchekwa nke ihe.
3. Ịtọkwa na nhazi nke oyi akwa mkpuchi okpomọkụ
Maka iwu vibration nke nnukwu ihe nkedo na-eguzogide okpomọkụ, ọrụ a bụkwa maka nkwadebe ihe owuwu.
Tupu ewu elu okpomọkụ eguzogide castable ọkụ mgbidi, mbụ dina asbestos osisi, calcium silicate osisi ma ọ bụ refractory eriri chere, wụnye metal njikọ, ebe arịlịka brik, na abuo dina insulating refractory brik ma ọ bụ wunye ìhè elu okpomọkụ na-eguzogide castables;Nke atọ bụ iwulite formwork.A ga-eji mmanụ ma ọ bụ akwụkwọ mmado na-ekpuchi elu na-arụ ọrụ nke ụdị ahụ, wee na-eru nso na njedebe na-arụ ọrụ nke brik arịlịka maka nkwado.The elu nke formwork wuru oge ọ bụla bụ 600 ~ 1000mm, ka ikwado loading na vibration ịkpụzi.N'ihe gbasara akpụkpọ ahụ nwa ebu n'afọ, a ga-ebu ụzọ kwado akpụkpọ ahụ nwa ebu n'afọ, mgbe ahụ, a ga-arụ ọrụ ahụ.A ga-eji ihe nkiri plastik kpuchie elu nke mkpuchi mkpuchi okpomọkụ ka ọ ghara ịmịnye mmiri ma na-emetụta arụmọrụ nke ihe nkedo.
Mgbe mgbidi ọkụ ahụ dị elu, a ga-ewukwa mkpuchi mkpuchi ahụ n'ígwé iji gbochie ịwụpụ ihe mkpuchi mkpuchi mgbe ihe na-agbapụta na-ama jijiji.
N'oge a na-ewu nnukwu ọkụ ọkụ refractory castable n'elu, a ga-arụzi ọrụ ahụ dum wee gbanye mmanụ dịka ihe achọrọ maka imewe;Mgbe ahụ kpọgidere brik ndị a kpọgidere n'elu oghere na-ebuli elu nwere njikọ ígwè.Ụfọdụ njikọ kwesịrị idozi ya na wedge osisi, ebe ndị ọzọ adịghị mkpa ka edozi ya.A ga-edobe brik ndị a kpọgidere n'okirikiri na ihu ọkụ ahụ na-arụ ọrụ.Ebe dị anya n'etiti ihu njedebe ala na ihu ihu ihu bụ 0 ~ 10mm, na njedebe nke brik ndị a na-ekokwasị na ihe karịrị pasent 60 ga-akpọtụrụ ihu ihu ihu.Mgbe oghere dị elu karịa 10mm, a ga-edozi njikọ nke ígwè iji mezuo ihe ndị a chọrọ.N'ihe banyere oghere, a ga-etinyekwa membranes ahụ nke ọma, mgbe ahụ, a ga-arụ ọrụ nhazi ahụ.
4. Ngwakọta
A ga-eji igwekota mmanye maka ịgwakọta.Mgbe ọnụ ọgụgụ nke ihe dị ntakịrị, ọ pụkwara iji aka gwakọta ya.Ngwakọta nke castables na-eguzogide okpomọkụ dị elu dị iche iche n'ihi ụdị dị iche iche;Maka ntinye akpa ma ọ bụ nchịkọta refractory na ciment, njehie a na-anabata bụ ± 1.0 pasent, njehie a na-anabata maka mgbakwunye bụ ± 0.5 pasent pasent, njehie na-ekwe ka hydrated mmiri mmiri na-ekekọta bụ ± 0.5 pasent pasent, na usoro ihe mgbakwunye kwesịrị ịbụ nke ziri ezi. ;A ga-awụsa ụdị akụrụngwa niile n'ime igwekota mgbe ha tụchara ya na-enweghị nkwụsị ma ọ bụ mgbakwunye.
N'ihi na Ịgwakọta elu okpomọkụ na-eguzogide castables dị ka ciment, ụrọ bonding na ala ciment usoro, mbụ wụsa akpa loading, ihe mgbakwunye na mgbakwunye n'ime igwekota na-etolite nnukwu ihe, na mgbe ahụ akọrọ mix ha maka 1.0min, na mgbe ahụ tinye mmiri ka. mmiri na-agwakọta ha maka 3-5 min mgbe ha mechara otu.Hapụ ha mgbe agba nke ihe bụ otu.Mgbe ahụ, a na-ebuga ya na nkwụ ma malite ákwà.
Maka ngwakọta nke sodium silicate na-eguzogide okpomọkụ na-eguzogide okpomọkụ, a pụrụ itinye ihe ndị na-emepụta ihe ma ọ bụ granules n'ime igwekota maka ikpokọta akọrọ, mgbe ahụ, a na-agbakwunye sodium silicate ngwọta maka ịgwakọta mmiri.Mgbe ejiri sodium silicate kechie granules, a na-agbakwunye ntụ ntụ ntụ na ihe ndị ọzọ.Ngwakọta mmiri dị ihe dị ka 5min, mgbe ahụ enwere ike ịhapụ ihe ndị ahụ maka ojiji;Ọ bụrụ na agwakọta ihe ndị akọrọ ọnụ, wụsa ha na mixer maka ịgwakọta akọrọ maka 1.0min, tinye 2/3 sodium silicate solution maka ịgwakọta mmiri maka 2-3min, ma gbakwunye ihe fọdụrụ na-ejikọta maka ịgwakọta mmiri maka 2-3min, mgbe ahụ. enwere ike iji ihe eji eme ihe.Ngwakọta resin na carbon nwere nnukwu ihe nkedo na-eguzogide okpomọkụ bụ otu ihe ahụ.
Maka ịgwakọta nnukwu ihe nkedo na-eguzogide okpomọkụ dị ka phosphoric acid na phosphate, buru ụzọ wụsa ihe akọrọ n'ime igwekota maka ngwakọta akọrọ maka 1.0min, tinye ihe dịka 3/5 nke ihe nkedo maka ngwakọta mmiri maka 2-3 min, wee wepụ ihe ahụ. , bufee ya na ebe a kara aka maka ịkwakọba, kpuchie ya na ihe nkiri rọba nke ọma, ma jide ihe ahụ maka ihe karịrị awa 16.A ga-atụnye ihe ndị ahụ tọrọ atọ na onye na-eme ngwa ngwa nke coagulant ma wụsa ya n'ime igwekota maka ngwakọta nke abụọ, a ga-agbakwunye ihe nkedo fọdụrụ maka ngwakọta mmiri maka 2-4min tupu eji ya.
Mgbe ị na-agwakọta castables nke na-eguzogide okpomọkụ dị elu, ọ bụrụ na ihe mgbakwunye dị ka eriri ígwè na-eguzogide okpomọkụ, ọkụ na-eguzogide ọkụ na organic fiber dị mkpa ka agbakwunyere na nkedo ahụ, a ga-agbasasị ha n'ihu n'ime ihe ngwakọta nke igwekota n'oge ngwakọta mmiri nke castables. .Ekwesịrị ịgbasa ha ma gwakọta ha n'otu oge ahụ, a gaghị etinye ha n'ime igwekota na otu.
Mgbe agwakọtara ngwakọta na igwekota, ọ bụrụ na ọ dị oke akọrọ, dị oke mkpa ma ọ bụ enweghị ihe ụfọdụ, a ga-atụfu ihe ahụ ma ghara itinye ya ọzọ;Ngwakọta a na-ahapụ na igwekota ga-adị n'ime 0.5 ~ 1.0h.
