Ndezvipi zvinhu zvinoda kutariswa mukuvaka kwe lightweight refractory zvidhinha muchando?

Chidhinha chakareruka cherefractory ndechimwe chezvinhu zvekare zvekuvaka. Inogona kushandiswa kunenge kwese kwese muindasitiri yekuvaka kusvika kune masonry. Kazhinji tine zvinodiwa panguva yekuvaka. Zvadaro, kunenge kuchitonhora munguva yechando uye pane zvinodiwa panguva yekuvaka. Ngatinzwisise kuti chii chinoda kubhadharwa mukuvakwa kwechando.

Chando chekuvaka chikamu

Kana kunze kwezuva nezuva kutonhora kwekushisa kwakaderera kudarika kana kuenzana ne5 ° C kwemazuva mashanu akatevedzana, kana kupisa kwemazuva ose kunodonha pasi pe5 ° C, chikamu chekuvaka kwechando chinopinda.

Kana tembiricha yemhepo yakadzikira kupfuura 0 ° C, dhaka refractory rinoshandiswa kugadzira masonry riri nyore kuomesa, uye hunyoro huri mumajoini edhaka huchawedzera nekuda kwechando. Iyo compactness yeash seam inoparadzwa. Iyo inowedzerawo porosity yemadota majoini. Izvi zvinoderedza zvakanyanya kunaka uye simba remasonry.

Kuvakwa kwechoto munguva yechando kunofanira kuitwa munzvimbo inopisa

Masonry industrial furnaces munguva yechando inofanira kuitwa munzvimbo inopisa. Tembiricha panzvimbo yekushanda uye yakatenderedza masonry haifanire kunge yakaderera pane 5 ℃. Iko kusanganiswa kwerefractory slurry uye isina kuumbwa refractory zvinhu zvinofanirwa kuitirwa mushedhi inodziya. Cement, formwork nezvimwe zvinhu zvinofanirwa kuchengetwa mushedhi inodziya. Apo simiti inoshandiswa pakuvaka zvidhinha zvitsvuku zve flue kunze kwechoto, nzira yechando inogona kushandiswa, asi mitemo inokosha yenzira yechando inofanira kushandiswa.

Kupisa kwemamiriro ekunze kwe refractory masonry munguva yechando

Paunenge uchivaka vira remaindasitiri munguva yechando, tembiricha yakatenderedza nzvimbo yebasa uye masonry haizodzike kupfuura 5 ° C. Choto chacho chakavakwa, asi choto chacho hachigoni kubikwa nokukurumidza. Matanho ekuomesa anofanirwa kutorwa, kana zvisina kudaro tembiricha yakatenderedza masonry haifanire kuderera kupfuura 5 ° C.

Refractory tembiricha control

Tembiricha yezvigadzirwa zvinoramba uye zvidhinha zvakafanogadzirwa zvinofanirwa kunge zviri pamusoro pe0 ℃ pamberi pemasonry.

Tembiricha yerefractory slurry, refractory plastic, refractory spray pendi uye simende refractory inokandwa panguva yekuvaka. Uyewo haifaniri kudzika kudarika 5°C. Clay-combined refractory castables, sodium silicate refractory castables, uye phosphate refractory castables haifaniri kunge yakaderera kupfuura 10 ° C panguva yekuvaka.

Tembiricha mamiriro refractory masonry kuvaka munguva yechando

Paunenge uchivaka mabiko emaindasitiri munguva yechando, muviri mukuru wechoto cheindasitiri uye nzvimbo yekushanda inofanirwa kuve yakashongedzwa neshedhi inodziya. Kupisa uye kupisa kunofanira kuitwa kana zvichidiwa. Iko kusanganiswa kwemoto slurry uye refractory castables kunofanirwa kuitwa mushedhi inodziya. Cement, formwork, zvidhinha, madhaka nezvimwe zvinhu zvinofanirwa kuendeswa mugreenhouse kuti zvichengetedzwe.

Zviri pamusoro apa ishumo pfupi yekuvaka zvidhinha zvisingaremi panguva yechando. Sezvo tembiricha munguva yechando yakadzikira, sumo iri pamusoro inofanira kunyatsoitwa. Chivakwa chacho hachifanire kunge chakanyanya kuomarara uye chinofanirawo kusanganiswa nemamiriro azvino chaiwo. Chete nekunyatsoita nhanho imwe neimwe zvakanaka, mhedzisiro yekuvaka ichave inogutsa uye chivakwa chichave chakavimbiswa.
