UkuZinzisa okuNgadityaniswanga kunye neSilicon Carbide Tube

Iityhubhu ze-silicon ze-carbide zezinye zamaqhawe angabonakaliyo kwii-ceramics zamashishini, Ukuma uqinile ngokuchasene namaqondo obushushu aphezulu kunye nokungcoliseka kweekhemikhali. I-Hexoloy alpha SiC ime njengenye yezona zinto zinzima ezenziweyo ezinomlinganiselo wobulukhuni be-Mohs 9.

Izixhobo zanamhlanje ze-ceramic kunye ne-alloy yensimbi zinika ukuqina okukhulu kunye nokuguquguquka xa kuthelekiswa nabangaphambili, ukunceda iinkampani ukuba zihlangabezane neenjongo zazo zokuzinza ngelixa zinciphisa iindleko zokulondoloza.

Ukuxhathisa ubushushu obuphezulu

Ityhubhu ye-silicon ye-carbide yimathiriyeli ye-ceramic ephezulu eyenzelwe ukumelana namaqondo obushushu aphezulu ngelixa ihlala yomelele kakhulu, ukwenza ukuba ilungele izicelo ezibandakanya amaziko oshishino, iityhubhu zokukhusela i-thermocouple kunye namanye amacandelo aphikisayo.

Izinto ezichasayo ezenziwe ngefiber ye-ceramic zifaneleke ngokufanelekileyo kwizicelo ezifuna ukuchasana ne-abrasion, ukubola kweekhemikhali kunye nokutshatyalaliswa kwe-thermal. Ngaphezulu, iphakathi kwezona zikhaphukhaphu zikhoyo kwaye izidla ngemodyuli yoMncinci ephezulu kuneyedayimani; oku kuvumela ukuba inikeze amandla aphezulu okuguquguquka kumaqondo obushushu aphakamileyo kunye namazinga aphantsi okwandiswa kwe-thermal kunye nokumelana nokuhlaselwa kweekhemikhali..

I-Kerui inikezela ngeetyhubhu zobumba ezidityanisiweyo kunye ne-silicon carbide zeceramic eyenzelwe ukwenza kwiimeko ezahlukeneyo ezinzima., ukusuka kwiintsimbi ze-metallurgical eziko ukuya kwiishelufu zeglasi. Iinjineli zethu zihlala zonwabile ukunceda ekukhetheni i-ceramic eyona ilungileyo kulo nakuphi na ukusetyenziswa okanye usetyenziso oluthile.

Amandla aphezulu

I-silicon carbide (I-sic) iityhubhu ngamacandelo afunwa kakhulu, ngenxa yobulukhuni babo, ukuzinza kwe-thermal kunye nokuchasana nokugqoka kunye nokubola. Njenge, ezi ityhubhu ze-SiC zenza ukuba iinkqubo zoshishino zibe namava okusebenza okongeziweyo, ukusebenza kakuhle kunye nokonga iindleko.

Banamandla amangalisayo adlula iiseramics zemveli kunye nealloys zetsimbi, ukubenza bafanelekele iimeko ezingqongileyo ezirhabaxa ezithanda ukukhukuliseka okanye ukonakala. Ngaphezulu, ezi zixhobo ezidibeneyo zinokumelana namaqondo obushushu ngaphandle kokubandezeleka kokuthotywa okanye ukuqhekeka – ilungele ukusetyenziswa kwiimeko ezimandundu ezifumana ukurhawuka rhoqo okanye ukhukuliseko.

Iityhubhu zokukhusela i-Thermocouple ezenziwe kwi-SiC ziyafumaneka zombini njenge-reaction bounded kunye neekeramics ezixutywe, ngalinye livelisa iziphumo ezahlukeneyo. Iiseramikhi ezidityanisiweyo ze-SiC ziveliswa ngokungena kwemixube ye-SiC kunye nekhabhoni enesilicon elulwelo., ngelixa i-sintered isebenzisa iindlela eziqhelekileyo zokuvelisa i-ceramic njengokuphosa, ukucinezela okomileyo okanye ukucinezela isostatic ukuvelisa ifom yabo ye-ceramic. Zombini ezi fom zomelele kakhulu kodwa ezona zibophelelekileyo zinokusebenzisa okongezelelekileyo njengokuntywiliselwa ngokuthe ngqo kwisinyithi esityhidiweyo njengealuminiyam okanye ubhedu ngokuthe ngqo..

Ukuxhathisa okuPhezulu kokuMnyama

I-Silicon carbide ime kakuhle ngokuchasene nomhlwa kwindawo engqongileyo, i-ceramics egqwesileyo kunye neentsimbi ze-ductile kwiimeko ezinzima. Ukumelana ne-Corrosion kunqunywe ngumgangatho kunye neenguqu ze-microstructural, ukukhuphisana kweekhemikhali kunye neendlela zokuthutha abantu abaninzi, kunye notshintsho kwi-morphology yezinto eziphathekayo.

I-SiC yaziwa ngokumelana nemekobume yeekhemikhali eziqatha ezinje ngee-slags zamalahle kunye ne-sludges ngaphandle kokuthotywa kwekhemikhali okanye ngokwasemzimbeni., iyenza ibe yinto efanelekileyo kumalungu afuna ukuxhathisa ukukrazuka komzimba okufana nemilomo yokudutyulwa kweqhuma, izitywina ze-ceramic kunye nezahluli ze-cyclone.

I-Kerui ibonelela ityhubhu ye-silicon carbide ene-sintered kunye ne-reaction-bonded kubungakanani obuninzi bokusetyenziswa kwizicelo zoxinzelelo oluphezulu.. Ityhubhu nganye yethu ine-hydrotested ukuya kuthi ga 165-186 bar yokuqinisekisa okongeziweyo ekuhlangabezaneni nezona mfuno ziqatha.

Ubomi obude

Ukuqina kwe-Silicon carbide kunye nokuphila ixesha elide kuyenza ibe yinto enqwenelekayo kwizicelo zamashishini ezifuna ukuthembeka kwexesha elide., ezifana nezixhobo zemigodi, imilomo yenjini ye-aerospace kunye nokugquma kwiziko lesinyithi elinyibilikisiweyo. Ngaphezulu, ukumelana kwayo neekhemikhali kunye namandla omatshini kuyenza ikwazi ukumelana noxinzelelo okanye ukugoba koxinzelelo olufumaneka kwiibheringi zetywina zoomatshini okanye izinto zempompo. – iimpawu eziqinisekisa ukuba isebenza ngokuthembekileyo phantsi kwayo nayiphi na imeko.

I-Hexoloy sintered silicon carbide iityhubhu zokukhusela i-thermocouple zibonelela ngeempawu eziphezulu zombane ezidityaniswe nokuqina., irefractoriness kunye nokugqwala / ukuxhathisa kwe-oxidation ye-silicon carbide material, i-coefficient ephantsi yezinga lokwandiswa kwe-thermal, ukuxhathisa okuphantsi kwezilwanyana kumaqondo obushushu aphakamileyo kunye nokumelana nokunyuka okungaqhelekanga – ukwenza ukuba zibe sisisombululo esigqibeleleyo kwiikhilni zetonela, ii-shuttle kunye ne-roller kilns, Irhasi yamafutha/iziko loshishino lweoyile kunye nezinto ezithwala imithwalo kwimizi-mveliso yamandla ngelixa idibana nokusebenza ngokufanelekileyo kunye neenjongo zokusebenza ngelixa zisahleli ziindawo zokusebenza ezikhuselekileyo.. Oku kubenza babe lukhetho olugqwesileyo kwii-tunnel kilns apho iinjongo eziphezulu zamandla kufuneka zifezekiswe ngelixa iindawo zokuhlala ezikhuselekileyo zokusebenza zigcinwa ngelixa ukufaneleka kwamandla kunye neenjongo zokusebenza zokusebenza kufuneka kuhlangatyezwane nazo ngelixa iindawo ezihlala zikhuselekile zokusebenza zigcinwa ngelixa izityalo zamandla zifezekisa amandla aphezulu kunye nokusebenza okusebenzayo ngelixa kudalwa iindawo zokusebenza ezikhuselekileyo..
