Umahluko kwi-thermal expansion coefficient phakathi kwezinto ze-precision granite kunye nezinto ze-ceramic ezichanekileyo zichaphazela njani ukusetyenziswa kwazo kwizixhobo ezichanekileyo?

Umahluko we-thermal expansion coefficient phakathi kwe-precision granite component kunye ne-precision ceramic component kunye nokusetyenziswa kwayo kwizixhobo ezichanekileyo kakhulu
Ekufuneni ukuchaneka okuphezulu kunye nokuzinza kwicandelo lemizi-mveliso, i-coefficient yokwandiswa kobushushu bezinto iba yinto ebalulekileyo. Izixhobo zegranite ezichanekileyo kunye nezixhobo zeseramikhi ezichanekileyo, njengeentlobo ezimbini zezinto ezisetyenziswa kakhulu kwizixhobo ezichanekileyo, umahluko wazo we-coefficient yokwandiswa kobushushu unempembelelo enkulu ekusebenzeni kwezixhobo.
Umahluko kwi-coefficient yokwandiswa kobushushu
Izixhobo zegranite ezichanekileyo:
I-granite njengelitye lendalo, i-coefficient yayo yokwandisa ubushushu iphantsi kakhulu, ngokubanzi iphakathi kwe-8 × 10 ^ -6 / ℃ ~ 10 × 10 ^ -6 / ℃. Oku kuthetha ukuba xa ubushushu butshintsha, utshintsho lobungakanani becandelo le-granite luncinci kakhulu, nto leyo enceda ukugcina uzinzo kunye nokuchaneka kwesixhobo. Ukongeza, i-granite inamandla okucinezelwa kakuhle, ukuqina kunye nokumelana nokuguguleka, okwenza ukuba ibe yindawo yokusebenza yezixhobo ezichanekileyo, ibhedi kunye nezinye izinto zezinto.
Izixhobo ze-ceramic ezichanekileyo:
Ngokwahlukileyo koko, i-coefficient yokwandiswa kobushushu kwezinto ze-ceramic ezichanekileyo iphantsi, idla ngokuba phantsi kakhulu kunezixhobo zesinyithi ezifana nentsimbi engagqwaliyo. Le coefficient iphantsi yokwandiswa kobushushu be-ceramics ezichanekileyo iyenza ikwazi ukugcina uzinzo oluphezulu kakhulu kunye nokuchaneka phantsi kotshintsho olukhulu lobushushu. Oku kubaluleke kakhulu kwizixhobo ezifuna ukusebenza kwiimeko ezichanekileyo ixesha elide, njengezixhobo ze-aerospace, izixhobo zokulinganisa ngokuchanekileyo, njl.
Impembelelo kwizixhobo ezichanekileyo kakhulu
Ukugcinwa kokuchaneka:
Kwizixhobo ezichanekileyo kakhulu, naluphi na utshintsho oluncinci lunokuba nefuthe elikhulu ekusebenzeni ngokubanzi kwezixhobo. Izixhobo zegranite ezichanekileyo kunye nezixhobo zeseramikhi ezichanekileyo, ngenxa yokwanda kobushushu obuphantsi, ziyakwazi ukugcina utshintsho oluncinci xa ubushushu butshintsha, ngaloo ndlela ziqinisekisa ukuchaneka kwexesha elide kunye nokuzinza kwezixhobo. Oku kubaluleke kakhulu kwizixhobo ezifuna ukulinganiswa okuchanekileyo, njengoomatshini bokulinganisa abalungelelanisiweyo, oomatshini be-lithography, njl.
Ukutshatisa:
Kwizixhobo ezichanekileyo kakhulu, ukufana phakathi kwezinto ezahlukeneyo kukwayenye yezinto eziphambili ezichaphazela ukusebenza kwezixhobo. Ngenxa yomahluko kwi-coefficient yokwandiswa kobushushu phakathi kwezinto ze-granite ezichanekileyo kunye nezinto ze-ceramic ezichanekileyo, lo mahluko kufuneka uqwalaselwe ngokupheleleyo kwinkqubo yoyilo kunye neyokuvelisa ukuqinisekisa ukufana okuhle phakathi kwezinto. Umzekelo, xa kuhlanganiswa izinto ze-ceramic ezichanekileyo kunye nezinto zesinyithi, iindlela ezikhethekileyo zokunxibelelana kunye nezixhobo ziyafuneka ukunciphisa uxinzelelo kunye neengxaki zokuguquguquka ezibangelwa kukungafani kwe-coefficients yokwandiswa kobushushu.
Isicelo esibanzi:
Kwizicelo ezisebenzayo, izinto zegranite echanekileyo kunye nezinto zeseramikhi ezichanekileyo zihlala zikhethwa kwaye zisetyenziswe ngokweemfuno ezithile. Umzekelo, kwizixhobo zokulinganisa ezichanekileyo, izinto zegranite echanekileyo zingasetyenziswa njengebhentshi yokusebenzela kunye nezinto zokulala ukuqinisekisa uzinzo kunye nokuchaneka kwezixhobo; Kwangaxeshanye, kwiindawo ezifuna ukuchaneka okuphezulu kunye notshintsho oluncinci, izinto zeseramikhi ezichanekileyo zinokwenziwa. Olu setyenziso lubanzi lunokunika ukudlala okupheleleyo kwiingenelo zezinto ezimbini kwaye luphucule ukusebenza kunye nokuthembeka kwezixhobo ngokubanzi.
Ngamafutshane, umahluko kwi-thermal expansion coefficient phakathi kwezinto ze-precision granite kunye nezinto ze-ceramic ezichanekileyo unempembelelo ebalulekileyo ekusetyenzisweni kwezixhobo ezichanekileyo. Ngokukhetha ngokufanelekileyo kunye nokusetyenziswa kwezi zinto zimbini, sinokuqinisekisa ukuba izixhobo zisenokugcina ukuchaneka okuphezulu kunye nozinzo kwimeko yokutshintsha kobushushu, ukuze kuhlangatyezwane neemfuno ze-high-precision machining kunye nokulinganisa.
