Muzviitiko zvakawanda zvemaindasitiri, michina inowanzo fanira kubata nemamiriro akasiyana-siyana ekushanda akaomarara, uye matambudziko ekusakara anokanganisa zvakanyanya hupenyu hwebasa uye kushanda zvakanaka kwemidziyo. Kubuda kwesimbi inodzivirira kusakara kwesilicon carbide kunopa mhinduro inoshanda kumatambudziko aya, uye zvishoma nezvishoma iri kuva nhoo yakasimba yemidziyo yeindasitiri.
Silicon carbide, chinhu chinoumbwa nekabhoni nesilicon, chine hunhu hunoshamisa. Kuoma kwayo kwakanyanya, kuri kwechipiri kune dhaimani rakaoma kwazvo, uye kuoma kwayo kweMohs kuri kwechipiri kune dhaimani, zvinoreva kuti inogona kuramba kukwenywa nekuchekwa kwezvidimbu zvakasiyana-siyana zvakaoma uye inoshanda zvakanaka mukudzivirira kupera. Panguva imwe chete, silicon carbide inewo coefficient yakaderera yekukweshana, iyo inogona kudzora mwero wekukweshana padanho rakaderera zvikuru mumamiriro ezvinhu akaoma akadai sekukweshana kwakaoma kana mafuta asina kunaka, zvichiwedzera hupenyu hwekushanda kwemidziyo.
Pamusoro pekuomarara uye kukweshana kwakaderera, hunhu hwemakemikari esilicon carbide hwakagadzikanawo, uye hunhu hwakanaka hwemakemikari. Inodzivirira ngura kubva kumaacid akasimba (kunze kwehydrofluoric acid nehot concentrated phosphoric acid), mabhesi akasimba, munyu wakanyungudutswa, uye simbi dzakasiyana-siyana dzakanyungudutswa (dzakadai sealuminium, zinc, copper). Hunhu uhwu hunoibvumira kushanda zvakanaka kunyangwe munzvimbo dzakaoma apo zvinhu zvinoparadza uye kupfeka zvinoenderana.
Kubva pamaonero ehunhu hwekupisa uye hwemuviri, silicon carbide inoratidzawo kushanda kwakanaka. Ine simba rekupisa rakawanda uye inogona kubvisa kupisa kunokonzerwa nekukweshana, ichidzivirira kupfava kwezvinhu kana kuputika kwekupisa kunokonzerwa nekupisa kwakanyanya kwemidziyo, uye ichiramba ichidzivirira kupfeka zvakanaka; Kuwanda kwayo kwekuwedzera kwekupisa kwakaderera, izvo zvinogona kuve nechokwadi chekuti michina yakagadzikana uye kuderedza kukuvara kwekupisa kwemidziyo panguva yekuchinja kwekushisa. Uyezve, silicon carbide inodzivirirwawo zvakanyanya, ine tembiricha yekushandisa inosvika 1350 ° C mumhepo (nzvimbo inooxidating) uye yakatokwira munzvimbo dzisina kusimba kana dzinoderedza kupisa.
Zvichibva pahunhu hwataurwa pamusoro apa, silicon carbide wear-resistant lining yakashandiswa zvakanyanya mumaindasitiri akawanda. Muindasitiri yemagetsi, mapaipi anoshandiswa kutakura zvinhu zvakaita semadota anobhururuka anowanzo kukurwa nezvidimbu zvakasimba zvinoyerera nekukurumidza, uye mapaipi ezvinhu zvakajairika anopera nekukurumidza. Zvisinei, mushure mekushandisa silicon carbide wear-resistant lining, kuramba kwepaipi kunovandudzwa zvikuru, uye hupenyu hwebasa hunowedzerwa zvakanyanya; Muindasitiri yemigodhi, kuiswa kwesilicon carbide wear-resistant lining pazvinhu zvisingatsvedzeri zvakadai semapaipi anofambisa slurry uye mukati me crusher kunoderedza kuwanda kwekugadzirisa michina uye kunovandudza kushanda zvakanaka; Muindasitiri yemakemikari, inotarisana ne corrosive media uye complex chemical reaction environments, silicon carbide wear-resistant lining haingogumiri pakusvedzeri, asiwo inodzivirira chemical corrosion, ichivimbisa kushanda kwakachengeteka uye kwakasimba kwemidziyo.
Muchidimbu, jira rinodzivirira kupfekwa kwesimbi yesilicon carbide rinopa dziviriro yakavimbika kumidziyo yeindasitiri nekushanda kwayo kwakanaka. Nekuvandudzwa kuri kuitwa nesainzi yezvinhu, kushanda kwejira rinodzivirira kupfekwa kwesimbi yesilicon carbide kucharamba kuchivandudzwa, uye mutengo unogona kuderedzwa zvakanyanya. Mune ramangwana, rinotarisirwa kushandiswa muminda yakawanda uye kuita basa rakakura mukushanda kwakanaka uye kwakasimba kwekugadzirwa kweindasitiri.
