Ekusebenzeni kwezixhobo zoshishino, kukho into engayihoywayo ngokulula kodwa ibalulekileyo - isitywina. Kufana “neringi yokutywina” yesixhobo, esinoxanduva lokwahlula ulwelo neegesi zangaphakathi, ukuthintela ukuvuza. Emva kokuba isitywina singaphumeleli, sinokuchaphazela ukusebenza kakuhle kwesixhobo okanye kubangele iingozi zokhuseleko. Phakathi kwezinto ezininzi zokutywina, iiseramics ze-silicon carbide ngokuthe ngcembe ziba "yintandokazi entsha" kwindawo yemizi-mveliso ephezulu ngenxa yeenzuzo zabo ezizodwa.
Abanye abantu banokuba nomdla, ngaba iiseramics azibuthathaka? Inokusetyenziswa njani ukwenza amatywina? Inyaniso,i-silicon carbide ceramicszihluke ngokupheleleyo kwiisitya ze-ceramic kunye neekomityi esizibona kubomi bethu bemihla ngemihla. Yimathiriyeli ye-ceramic ephuculweyo eyenziwe ngeenkqubo ezikhethekileyo, enobunzima besibini kuphela kwidayimane. Amatywina enziwe ngayo kuqala asombulule ingxaki yezinto zokutywina zendabuko ukuba "zingenakunxitywa". Kwisixhobo esinesantya esiphezulu esinje ngeempompo zamanzi kunye necompressor, izitywina kufuneka zixutywe namanye amacandelo ixesha elide, kwaye izinto eziqhelekileyo ziya kunxiba kwaye zikhubazeke kungekudala. Nangona kunjalo, ukuxhatshazwa kwe-silicon carbide ceramics kubavumela ukuba "banamathele kwizithuba zabo" ixesha elide phantsi kweemeko zokusebenza ezinzima, ukwandisa kakhulu ubomi benkonzo yezixhobo.
Ukongeza kokunganyangeki, ukumelana nobushushu obuphezulu kunye nokumelana nomhlwa zizinto ezikhethekileyo zesilicon carbide ceramic seals. Kumashishini afana neekhemikhali kunye ne-metallurgical, izixhobo zihlala zidibana nemithombo yeendaba ezonakalisayo ezifana ne-asidi eyomeleleyo kunye ne-alkalis, kwaye inokumelana namaqondo obushushu angamakhulu okanye amawaka amaqondo eCelsius. Izitywina zentsimbi zemveli zithande ukubola kunye nokuguqulwa kumaqondo obushushu aphezulu, ngelixa izitywina zerabha zithambile kwaye zisilela kumaqondo aphezulu. I-Silicon carbide ceramics ayikwazi nje ukuxhathisa ukukhukuliseka kwezinto ezahlukeneyo zeekhemikhali, kodwa iphinde igcine ukusebenza okuzinzileyo kwiindawo eziphakamileyo zokushisa, ngaphandle kokuguqulwa, ukuqhekeka kunye nezinye iingxaki, ukubonelela ngesiqinisekiso sokusebenza ngokukhuselekileyo kwezixhobo phantsi kweemeko ezinzima.
Kuyafaneleka ukukhankanya ukuba izitywina ze-silicon carbide ceramic nazo zineempawu "ezilula" kunye "ne-friction ephantsi". Ubuninzi bayo buncinci kunobuntsimbi, obunokunciphisa ubunzima obupheleleyo bezixhobo; Ngelo xesha, ubuso bayo buhamba kakuhle kwaye i-friction coefficient iphantsi, enokunciphisa ukusetyenziswa kwamandla ngexesha lokusebenza kwaye incede izixhobo zifezekise ukusebenza kakuhle. Oku ngokungathandabuzekiyo yeyona nto iphambili kumashishini anamhlanje alandela ugcino lwamandla kunye nokunciphisa ukusetyenziswa.
Ukususela kumatywina angabonakaliyo ukuya "kwindoda ephambili" exhasa ukusebenza okuzinzile kwezixhobo zoshishino eziphezulu, i-silicon carbide ceramics ibonisa amandla "okutshintsha izinto zoshishino". Ngokuphuculwa okuqhubekayo kweemfuno zokusebenza kwezixhobo kwintsimi ye-industrial, esi sitywina se-ceramic, esidibanisa iingenelo ezifana nokunganyangeki, ukumelana nobushushu obuphezulu, kunye nokumelana nokugqwala, kuya kudlala indima ebalulekileyo kwiinkalo ezininzi kwixesha elizayo kwaye ibe "ngumlindi" wokwenene wezixhobo zoshishino.
