Yiziphi izinto ezidinga ukunakwa ekwakhiweni kwe lightweight refractory izitini ebusika?

I-lightweight refractory brick ingenye yezinto zokwakha zasendulo. Ingasetshenziswa cishe yonke indawo embonini yezokwakha ngokuphathelene nokwakhiwa kwamatshe. Ngokuvamile sinezidingo ngesikhathi sokwakha. Khona-ke, kubanda kakhulu ebusika futhi kunezidingo lapho kwakhiwa. Ake siqonde ukuthi yini okudingeka inakwe ekwakhiweni kwasebusika.

Isigaba sokwakha sasebusika

Uma izinga lokushisa elivamile langaphandle lansuku zonke lingaphansi noma lilingana no-5°C izinsuku ezingu-5 ezilandelanayo, noma izinga lokushisa eliphansi nsuku zonke lehla ngaphansi kuka-0°C, isigaba sokwakha sasebusika siyangenwa.

Uma izinga lokushisa lomoya lingaphansi kuka-0 ° C, udaka oluphikisayo olusetshenziselwa ukwakha kulula ukufriza, futhi umswakama emalungeni odaka uzokhula ngenxa yokuqhwa. Ukubumbana komthungo womlotha kuyabhujiswa. Ibuye ikhulise i-porosity yamalunga omlotha. Lokhu kunciphisa kakhulu izinga namandla we-masonry.

Ukwakhiwa kwesithando somlilo ebusika kufanele kwenziwe endaweni yokushisa

Izithando zezimboni zamatshe ebusika kufanele zenziwe endaweni yokushisa. Izinga lokushisa endaweni yokusebenza nasezindaweni ezizungezile akumele libe ngaphansi kuka-5℃. Ukuxutshwa kwe-refractory slurry kanye nezinto eziphikisayo ezingashintshiwe kufanele zenziwe endaweni efudumele. Usimende, i-formwork nezinye izinto kufanele zigcinwe endaweni efudumele. Lapho udaka lukasimende lusetshenziselwa ukwakha izitini ezibomvu ze-flue ngaphandle kwesithando somlilo, indlela yokuqandisa ingasetshenziswa, kodwa imithetho ekhethekile yendlela yokuqandisa kufanele isetshenziswe.

Ukushisa kwemvelo kwe-refractory masonry ebusika

Lapho wakha izithando zomlilo ezimbonini ebusika, izinga lokushisa elizungeze indawo yokusebenza kanye nendawo yokusebenzela akumele libe ngaphansi kuka-5°C. Isithando somlilo sakhiwe, kodwa isithando somlilo asinakubhakwa ngokushesha. Izinyathelo zokomisa kufanele zithathwe, ngaphandle kwalokho izinga lokushisa elizungeze i-masonry akufanele libe ngaphansi kuka-5 ° C.

Ukulawula izinga lokushisa eliphikisayo

Izinga lokushisa lezinto eziphikisayo namabhulokhi akhiwe kusengaphambili kufanele libe ngaphezu kuka-0℃ ngaphambi kokwakhiwa kwamatshe.

Izinga lokushisa le-refractory slurry, ipulasitiki eyi-refractory, upende wesifutho esiphikisayo kanye nesici esiphikisayo sikasimende esikwazi ukuphonswa ngesikhathi sokwakha. Akufanele futhi ibe ngaphansi kuka-5°C. Izinsimbi eziphikisayo ezihlanganiswe ngodaka, okusansimbi okuphikisayo kwe-sodium silicate, kanye nezinsimbi eziphikisayo ze-phosphate akufanele zibe ngaphansi kuka-10°C ngesikhathi sokwakhiwa.

Izimo zokushisa zokwakhiwa kwe-masonry refractory ebusika

Lapho wakha izithando zezimboni ebusika, umzimba oyinhloko wesithando somlilo wezimboni kanye nendawo yokusebenza kufanele ifakwe ishede elifudumele. Ukushisisa nokudubula kufanele kwenziwe uma kunesidingo. Ukuxutshwa kwe-fire slurry kanye ne-refractory castables kufanele kwenziwe endaweni efudumele. Usimende, i-formwork, izitini, udaka nezinye izinto kufanele zihanjiswe ku-greenhouse ukuze zigcinwe.

Okungenhla isingeniso esifushane sendlela yokwakha izitini ezikhanyelayo ezilula ebusika. Njengoba izinga lokushisa ebusika liphansi ngokuqhathaniswa, isingeniso esingenhla kufanele sisetshenziswe ngokuqinile. Ukwakhiwa akufanele kuqine kakhulu futhi kufanele futhi kuhlanganiswe nesimo esiqondile samanje. Kuphela ngokwenza ngokuqinile zonke izinyathelo kahle, imiphumela yokwakhiwa izokwanelisa futhi isakhiwo sizoqinisekiswa.
