Ukuhlola iLining Resistant Wear yeSilicon Carbide: Umgcini Ongabonakaliyo Wezixhobo Zoshishino

Kwicandelo lemizi-mveliso, izixhobo zihlala zijongene nemingeni eyahlukeneyo enzima yokusingqongileyo, kwaye ukuguguleka ngomnye wemingeni emikhulu. Ukuguguleka akunciphisi nje kuphela ukusebenza nokusebenza kakuhle kwezixhobo, kodwa kunokukhokelela ekusileleni kwezixhobo, ukonyusa iindleko zokulungisa kunye nexesha lokungasebenzi. Ukuvela kwei-silicon carbide engagugiyoifana nomlindi ongabonakaliyo, omelana nokuguguleka kwaye wandisa ubomi benkonzo yezixhobo. Namhlanje, siza kuyityhila ikhuselo layo eliyimfihlakalo size sihlolisise umgaqo walo wokusebenza.
I-silicon carbide (i-SiC) yi-compound eyenziwe ngezinto ezimbini, i-silicon kunye ne-carbon. Ulwakhiwo lwayo lwekristale luhlukile kakhulu, kunye neeyunithi zesakhiwo ezisisiseko ezidityanisiweyo ze-SiC kunye ne-CSi tetrahedra. Olu lwakhiwo luqinileyo noluzinzileyo lunika i-silicon carbide iipropati ezininzi ezintle, ezinje ngokumelana nobushushu, ukumelana nokugqwala, ubunzima obuphezulu, kunye nokumelana nokugqwala, okwenza ukuba ibe yinto efanelekileyo yokwenza i-lining engagugiyo.
Ngoko ke, i-lining engagugiyo eyenziwe nge-reaction sintered silicon carbide ceramics isebenza njani?
Ubunzima obuphezulu bokumelana nokuguguleka: Iiseramiki zesilicon carbide ezisebenzisa i-reaction sintered zinobunzima obuphezulu kakhulu, zilandela idayimani kuphela. Xa amasuntswana angaphandle ebetha okanye egudla udonga lwangaphakathi lwesixhobo, i-lining enganyangekiyo, enobunzima bayo obuphezulu, inokumelana ngempumelelo nomonakalo wale mikhosi yangaphandle, njengekhaka eliqinileyo, inciphisa kakhulu ukuguguleka kwesixhobo kwaye yandise ubomi benkonzo yesixhobo.
Uzinzo oluhle lweekhemikhali nxamnye nokugqwala: Kwiimeko ezininzi zoshishino, izixhobo azijongani nje nokugqwala, kodwa zikwadibana neekhemikhali ezahlukeneyo, nto leyo ebangela umngcipheko wokugqwala. Iiseramikhi zesilicon carbide ezisebenzisa i-reaction sintered zinozinzo oluhle lweekhemikhali kwaye zinokuthintela ngempumelelo ukugqwala ziikhemikhali, ngaloo ndlela ziqinisekisa ukusebenza okuqhelekileyo kwe-lining engagugiyo kwiindawo ezintsonkothileyo zeekhemikhali.

Ukumelana nobushushu obuphezulu kunye nokuzivumelanisa neemeko zobushushu obuphezulu: Ezinye iinkqubo zemveliso yemizi-mveliso zinokubangela ubushushu obuphezulu, kwaye izinto eziqhelekileyo zinokuba zithambile, ziguquguquke, okanye zonakale nakwiimeko zobushushu obuphezulu. Nangona kunjalo, iiseramikhi ze-silicon carbide ezisabelayo zinokufikelela kubushushu obuphezulu bokusebenza obuyi-1350 ℃ kwaye zingasetyenziswa ngokuzinzileyo ixesha elide nangona zikwimeko yobushushu obuphezulu. Zinokuthintela ngempumelelo izinto kunye neenxalenye ekubeni ziguquke kwaye zithambe ngenxa yobushushu obuphezulu, ziqinisekise ukuba ii-liners ezingagugiyo zisenokubonelela ngokhuseleko oluthembekileyo kwizixhobo kwiindawo zobushushu obuphezulu.
Xa kuthelekiswa nezinye iintlobo zezinto zelineni ezingagugiyo, i-reactive sintered silicon carbide ceramic wear-resistant lining ineenzuzo ezicacileyo. Umzekelo, ubulukhuni bayo budlula kakhulu obo be-ceramics eziqhelekileyo ezifana ne-alumina kunye ne-zirconia, kwaye ingcono kakhulu ekugugiseni; Uzinzo lwayo lweekhemikhali kunye nokumelana nobushushu obuphezulu nako kubhetele kakhulu kunezinye izinto zemveli, kwaye inokuqhelana neendawo zokusebenza ezinzima nezinzima.
I-silicon carbide engagugiyo isetyenziswa kakhulu kumashishini ahlukeneyo afana namandla, intsimbi, iiseramikhi, ii-oven ezishushu kakhulu, ukumbiwa kwemigodi, amalahle, ipetroliyam, iikhemikhali kunye noomatshini. Kule mashishini, ikhusela izixhobo ezininzi, iqinisekisa imveliso egudileyo, kwaye inciphisa iindleko zokusebenza kumashishini.
I-silicon carbide engagugiyo idlala indima ebalulekileyo kwicandelo lemizi-mveliso ngenxa yokusebenza kwayo okwahlukileyo kunye nokusebenza kakuhle. Njengomvelisi ochwephesha we-reaction sintered silicon carbide ceramics, iShandong Zhongpeng ibisoloko izibophelele ekuboneleleni abathengi ngeemveliso ezisemgangathweni ophezulu, inceda amashishini ahlukeneyo ukuphucula ukusebenza kwezixhobo, kunye nokufezekisa imveliso esebenzayo. Ukuba unomdla kwiimveliso zethu, nceda uzive ukhululekile ukunxibelelana nathi nangaliphi na ixesha kwaye usivumele sinegalelo kuphuhliso lweshishini kunye.
