Yintoni umahluko phakathi izitena ezikhanyelayo kunye nezitena zokugquma?

Umsebenzi oyintloko wezitena zokufakela i-thermal kukugcina ukufudumala nokunciphisa ukulahleka kobushushu. Izitena zokugquma i-thermal aziwuchukumisi ngokuthe ngqo idangatye, ngelixa izitena eziphikisayo zichaphazela ngokuthe ngqo idangatye. Izitena ezixhathisayo zisetyenziswa ikakhulu ukumelana nokutsha kwamadangatye. Ngokuqhelekileyo zohlulwe zibe ziindidi ezimbini, ezizezi, iirefractories ezingamiliselwanga kunye nezichasi ezimile. Imathiriyeli engamiliselwanga yerefractory: ekwabizwa ngokuba yi-castable, yigranule engumgubo oxubeneyo owenziwe ziindidi zeeaggregates okanye iaggregates kunye nesibophelelo esinye okanye ngaphezulu. Kufuneka ixutywe nolwelo olunye okanye ngaphezulu kwaye ixutywe ngokulinganayo ngexesha lokusetyenziswa. Unamandla okuhlawula amatyala. Izinto eziphikisayo ezibunjiweyo: ngokuqhelekileyo zenziwe ngezitena eziphikisayo, imilo enemigaqo esemgangathweni, kwaye inokucutshungulwa okwethutyana ngokweemfuno xa kwakhiwa kunye nokusika.

Umahluko ophambili phakathi kwezitena zokufakelwa kwe-thermal kunye nezitena eziphikisayo zezi zilandelayo:

1. Ukusebenza kwe-thermal insulation

I-thermal conductivity yezitena zokufakelwa kwe-thermal ngokuqhelekileyo yi-0.2-0.4 (iqondo lokushisa eliphakathi kwama-350±25 ° C) w/mk, ngelixa ukuhanjiswa kwe-thermal yezitena eziphikisayo kungaphezulu kwe-1.0 (iqondo lobushushu eliphakathi kwama-350±25°C) w/mk, kunye Isitena sokufakelwa kwe-thermal sinokufumaneka. Ukusebenza kwe-thermal insulation ye-Refractory Brick ingcono kakhulu kunezitena eziphikisayo.

2. Ukujonga kwakhona

I-refractoriness ye-insulation izitena ngokuqhelekileyo ingaphantsi kwe-1400 degrees, ngelixa i-refractoriness yezitena eziphikisayo zingaphezulu kwe-1400 degrees.

3. Ubunzima

Izitena ze-insulation ngokubanzi zizinto zokugquma ezinobunzima obulula, kunye nobuninzi be-0.8-1.0g / cm3 kwaye ubuninzi bezitena eziphikisayo zingaphezulu kwe-2.0g / cm3.

Ngokuqhelekileyo, izitena eziphikisayo zinamandla amakhulu omatshini, ubomi benkonzo ende, ukuzinza kweekhemikhali ezilungileyo, akukho mpendulo yeekhemikhali kunye nezixhobo kunye nokumelana nokushisa okuphezulu. Ubushushu obuphezulu bokumelana nobushushu bunokufikelela kwi-1900 ℃. Kufanelekile ngokukhethekileyo kwiindawo zokushisa eziphezulu kunye nezisezantsi zokushisa, abahlaziyi, i-hydroconverters, iitanki ze-desulfurization kunye ne-methanizers kwizityalo zesichumisi sekhemikhali ukusabalalisa igesi kunye nolwelo, kunye nokuxhasa, ukugubungela nokukhusela i-catalysts. Isenokusetyenziswa kwizitovu ezitshisayo kunye nezixhobo zokuguqula ukufudumeza kwishishini lentsimbi kunye nentsimbi.

Izitena eziphikisayo zineenzuzo zokuxinana okuphezulu, ukomelela okuphezulu, ukuxhathisa ukunxiba, ukuxhathisa okulungileyo kwe-corrosion, i-coefficient ephantsi yokwandisa i-thermal, ukusebenza kakuhle kokusila, ingxolo ephantsi, ubomi benkonzo ende, kunye nezixhobo ezingangcolisi. Yindlela yokugaya ilungele oomatshini abahlukeneyo bokugaya.

Izitena eziphikisayo zihluke kakhulu kwizitena zokufakelwa kwe-thermal, kunye nokusingqongileyo kokusetyenziswa kwazo, ububanzi kunye nomsebenzi zihluke. Izinto ezahlukeneyo ziya kusetyenziswa kwiindawo ezahlukeneyo. Xa sikhetha izinto eziphathekayo, kufuneka senze isigqibo sokuba yeyiphi into ephikisayo efanelekileyo yokusetyenziswa kwethu ngokwemeko yethu yokwenyani.
