Chimiro chesimbi chinoumbwa nechimiro chezvinhu zvesimbi, ndicho chimwe chezvimiro zvikuru zvechivakwa.
Chimiro chesimbi chine hunhu hwesimba guru, huremu hwakapfava, kuomarara kwakanaka uye kugona kuchinjika kwakasimba, saka chinogona kushandiswa pakuvaka zvivakwa zvakareba uye zvakareba zvikuru, zvinorema zvikuru. Simba rechinhu chinodiwa pakuvaka simbi rinobva pakukwanisa kwayo kuchinjika. Kana simbi yakawedzera kunaka kwayo, ine hunhu hwekuchinja kukuru kwepurasitiki isina kutyoka.
1, simba guru rezvinhu, huremu hwakareruka. Simbi ine simba guru uye modulus yakakwira inochinjika. Kana ichienzaniswa nekongiri nehuni, huwandu hwayo hwekuwanda uye simba rekukohwa hwakaderera, saka pasi pemamiriro akafanana ekumanikidzwa kwesimbi, chikamu chidiki, huremu hwakareruka, zviri nyore kutakura uye kuisa, zvakakodzera kureba kukuru, kureba, uye chimiro chinorema.
2, kusimba kwesimbi, purasitiki yakanaka, zvinhu zvakafanana, kuvimbika kwakanyanya kwechimiro. Yakakodzera kubatwa kwebheya uye mutoro unochinja-chinja, ine mashandiro akanaka ekutinhira kwepasi. Chimiro chemukati chesimbi chakafanana, chakafanana neyunifomu yeisotropic. Kushanda chaiko kwechimiro chesimbi kunoenderana nedzidziso yekuverenga. Saka chimiro chesimbi chakavimbika zvikuru.
3, kugadzira simbi uye kuisa michina ine mwero wepamusoro. Zvimiro zvesimbi zviri nyore kuunganidza mufekitori nenzvimbo. Kugadzira simbi yakagadzirwa nefekitori nemidziyo ine magadzirirwo akanyanya, kushanda zvakanaka, kukurumidza kuunganidza uye nguva pfupi yekuvaka. Chimiro chesimbi ndechimwe chezvivakwa zvine maindasitiri akawanda.
4, kushanda kwesimbi mukuvhara simbi kwakanaka, nekuti simbi inogona kuvharwa zvachose, inogona kugadzirwa kuti ive mhepo yakasimba, mvura yakasimba zvakanaka, midziyo yemafuta yakakura, mapaipi ekumanikidza, nezvimwewo.
5, simbi haipindi kupisa kana kupisa kuchiitika uye haipindi kupisa, kana tembiricha iri pasi pe150°C, simbi haichinji zvakanyanya. Saka, simbi inopinda zvakanaka panzvimbo inopisa, asi pamusoro pechivako ichi inodzivirirwa nekupisa kana mwaranzi yekupisa iri pa150°C. Tembiricha iri pakati pe300°C ne400°C. Simba uye elastic modulus yesimbi yakaderera zvakanyanya, uye simba resimbi rakaita zero kana tembiricha iri pa600°C. Muzvivakwa zvine zvinodiwa zvekudzivirira moto, zvivakwa zvesimbi zvinofanirwa kuchengetedzwa nezvinhu zvinodzivirira moto kuti zviwedzere kunaka kwekudzivirira moto.
6, kuramba ngura kwechimiro chesimbi hakuna kunaka, kunyanya munzvimbo ine ngura dzakanyorova uye dzakanyorova, zviri nyore kuita ngura. Chimiro chesimbi chakajairika kuti chisaparare, chakabatidzwa kana kupendwa, uye kugadziriswa nguva dzose. Matanho akakosha akadai se "zinc block anode protection" anofanirwa kushandiswa kudzivirira ngura yezvivakwa zvepuratifomu yegungwa mumvura yegungwa.
7, kabhoni shoma, kuchengetedza simba, kuchengetedzwa kwezvakatipoteredza, inogona kushandiswazve. Kuputswa kwezvivakwa zvesimbi hakuiti kuti pave nemarara mashoma ekuvaka, uye simbi inogona kudzokororwa.
