Izici ezibalulekile zezitini ze-silica

 

Izitini ze-Silica ziwuhlobo lwesitini esibusayo sezenziwe ngokuyinhloko kusuka ku-silica (Sio2}} Ziyaziwa ngokuqukethwe okuphezulu kwe-silica okuphezulu nokuphikisana namakhemikhali {ama-kilns, ukukhiqizwa kwengilazi, kanye nezinye izinqubo zezimboni .
Nazi ezinye zezimpawu ezibalulekile zezitini ze-silica:


Ukumelana nokushisa okuphezulu:Izitini zeSilica zingamelana namazinga okushisa aphezulu kakhulu, ngokuvamile zifinyelela ku-1650℃(3000℃f) noma ngaphezulu, ngokuya ngekhwalithi ye-Brick


Ukumelana nokuthuthumela okushisayo:I-Silica Bricks ibonisa ukumelana okuhle kokushaqeka okushisayo, okubalulekile kuzinhlelo zokusebenza lapho kuvela khona izinguquko zokushisa okusheshayo {{0


Ukumelana Kwamakhemikhali:Izitini ze-Silica zinokumelana kahle kwamakhemikhali, kubenza bamelane nemiphumela yama-acid, i-alkali, nezinye izinto eziwonakele . zilungele kakhulu izinhlelo zokusebenza lapho izitini zihlangana khona nezindawo ezinolaka kwamakhemikhali .


I-coefficion ephansi ephansi:Izitini ze-Silica zine-coefficition ephansi yokwanda okushisayo, okusho ukuthi bayanda futhi banenkontileka kancane uma kuqhathaniswa nezinye izinto zokuvuselela izinguquko {{0}


Izakhiwo ezifakiwe:Izitini ze-Silica zinezakhiwo ezinhle zokufakwa okufakwayo, ezisiza ukugcina ukushisa ngaphakathi kwesithando noma esiln futhi kuthuthukise ukusebenza kahle kwamandla . zinciphisa ukulahlekelwa ukushisa futhi zilondoloze izinga lokushisa elizimele

 

 
Ubuchwepheshe Bokukhiqizwa Kwe-Silica Brick
 

Ukukhiqizwa kwezitini ze-silica, ngaphezu kokunaka umgomo wokupakisha okusondele kakhulu, ithonya lenqubo yokuxuba, ingcindezi yokubumba, izimo zokudubula nezinye izici kufanele futhi ibhekwe ngokuphelele .
Inqubo yokukhiqiza izitini ze-silica imvamisa ifaka lezi zinyathelo ezilandelayo:

01/

Ukulungiselela Okubonakalayo Okubonakalayo:Isinyathelo sokuqala ukukhetha izinto ezingavuthiwe ezisezingeni eliphakeme, izinsiza ezicebile ze-silica ezinjenge-quartzi, isihlabathi se-silica, noma i-ganister . Ukusetshenziswa kosayizi ovuthiwe

02/

Ukuxuba:Izinto ezichotshoziwe futhi ezinomhlabathi ezihlanganisiwe zihlanganiswa kahle namanzi noma i-tinder ukwakha isisindo seplastiki noma sepulasitiki {{1}

03/

Ukubumba:Isisindo sepulasitiki noma sepulasitiki sibunjwe ngezitini sisebenzisa amasu ahlukahlukene okubumba njengokukhishwa, ukucindezela, noma ukukhonkotha

04/

Ukomisa:Izitini ezibunjiwe zomiswa ukususa umswakama owengeziwe futhi zithuthukise amandla azo {{0}

05/

Ukudubula:Izitini ezomisiwe zifakwa kwinqubo yokudubula okushisa kakhulu eyaziwa ngokuthi yi-sontering . Izithelo zokudubula izitini zivame ukuzungeza ama-kilns noma izithelo, futhi kancane kancane izinga lokushisa lenyuke Ukunwetshwa . Inqubo yokudubula isiza ukufaka impahla eluhlaza ndawonye futhi iluguqule ibe isakhiwo esiminyene futhi esizinzile .

06/

Ukupholisa nokuhlola:Ngemuva kwenqubo yokudubula, i-kiln noma isithando somlilo ivunyelwe ukupholisa kancane ekushiseni kwegumbi . Izitini ze-silica ezipholile zibe sezihlolelwa izakhiwo ezahlukahlukene ezinjengokuqina, nokuqina okushisayo ukuze kuqinisekiswe imininingwane efiselekayo .

 

Silica Brick - Izakhiwo Ezibonakalayo
 

Ukumelana Nesisekelo se-Acid
I-Silica Brick iyinto ebonakalayo ye-acidic, enokumelana okuqinile kokuguguleka kwe-acidic slag, kepha lapho ihlushwa ngokuqinile yi-oxides enjenge-ai2o3, futhi ilimala kahle ku-oxides as cao, Feo, ne-Feo2o 3.


Ukukhishwa
Ukuvuselelwa okushisayo kwezitini ze-silica kukhuphuka ngokunyuka kokushisa okusebenzayo, ngaphandle kwe-shrinkage ebekiwe Ukunwetshwa [

Ukushisa kwe-Deformation Ngaphansi komthwalo
Izinga lokushisa eliphakeme eliphakeme ngaphansi komthwalo liyithuba lezitini ze-silica, eziseduzane nendawo yokuncibilika ye-tridmite ne-cristobalite, okuphakathi kuka-1640 no-1680℃.


Ukuqina okushisayo
Isihluthulelo Sokuthola Ukuqina Okushisayo Kwezitini zeSilica ukuqina, futhi ubuningi kungenye yezimpawu ezibalulekile ukunquma ukuguqulwa kwe-quartz . Ukwelulwa kwe-lime

 

Isitini se-silica

 

● Isitini somlilo weSilica iyinto ebonakalayo ye-acid-refractory, futhi ukumelana kahle nokushisa kwe-acid, kanye nokushisa okuthambile okufika ku-1640 ~ 1670 degree, umthamo wokusetshenziswa kwesikhathi eside kumazinga okushisa aphezulu aqinile .


● Isetshenziswa ikakhulukazi odongeni oluhlukanisayo lwegumbi lokushiswa kwegumbi le-chorarring negumbi lokuvutha le-oven ye-coke, igumbi lokushisa elishisayo, isithando somlilo esishisayo, nezinye izingxenye zomthwalo we-kiln, nezinye izingxenye zomthwalo we-kiln ingxenye ethe lokushisa eliphakeme lokushisa lomthwalo wesithamule esishisayo nophahla lwamathayela ane-acid-flat .


● Kuyinto ikakhulukazi esetshenziswayo ye-acidic refractory ehlanganiswe i-quartz e-scartz, i-quartz yesikwele, nenani elincane le-quartz elisaseleyo kanye nesigaba se-silicon dioxide of 94% noma ngaphezulu 3.
Ukumelana ne-Acidic Slag Erosion . Amandla aphezulu okushisa aphezulu
I-Natural Silica njengento eluhlaza, kanye nenani elifanele le-ejenti yamaminerali, ukukhuthaza ukuguqulwa kwe-quartz emzimbeni ongenalutho kuye, ukukala kancane ngaphansi kokunciphisa umkhathi ngo-1350 ~ 1430 degree}
Ukushisa ku-1450℃mayelana ne-1 . 5 ~2% yenani eliphelele levolumu, lokhu kunwebeka okusele kuzonciphisa amalunga eduze, ukuze kuqinisekiswe ukuthi umzimba wokumanzisa unomoya omuhle namandla enhlaka.
I-Scalar Quartz, i-argealeous quartz, ne-quartz ebelayo inezinguquko ezinkulu ngevolumu ephansi ngenxa yokushintshana ngohlobo lwe-crystal, ngakho-ke ukuqina okushisayo kwezitini ze-silica kumazinga okushisa aphansi ampofu .
Ngesikhathi sokusetshenziswa, kufanele kufudushwe futhi kuphole kancane ngaphansi kwezinga elingu-800 ukugwema ukuqhekeka {{1}


● Uhlobo nenqubo yezitini ze-silica zihlobene kakhulu nokuguqulwa kwe-crystalline ye-SIO {{0}
Izidingo ezijwayelekile ku-2 . 38 noma ngaphansi, izitini eziphakeme zeSilica Refractory kufanele zibe ngu-2 . 35 noma ngaphansi. Ubungako obuthile beqiniso buncane, bukhombisa izitini ngenani le-quartz yesikali kanye ne-square quartz, inani le-quartz elisele lincane, ngakho-ke ukwandiswa okunensathi kwehlayo kuncane, futhi ukusetshenziswa kwehla kwehlathi kuncane.
I-Silicon Dioxide inokuhlukahluka okuyisikhombisa okuhlukahlukene kanye nokwehluka okukodwa kwe-Amorphous {{0} Isakhiwo sabo siyafana, futhi ukuguqulwa phakathi komunye nomunye kushesha .


● Izinto ezivuthiwe zokwenziwa kwezitini ze-silica yi-silica . ezintweni ezisetshenziswayo ze-silica, okuphezulu kwe-SIO2, okuphezulu kwe-SIO2, zinciphisa kakhulu ukungcola kwemikhiqizo ebonakalayo .
Izitini ze-Silica zenziwa nge-silica nge-SIO2 okuqukethwe okungaphansi kwama-96%, ukungeza i-ejenti ye-mineralizing (e ., i-ejenti ebolekayo (e {{5 pulp imfucuza) ukomisa, kanye nezinqubo ze-sontering .
