Ndeupi musiyano uripo pakati pekuwedzera kwekupisa pakati pemubhedha wesimbi yakakandwa nemubhedha wemineral yakakandwa? Musiyano uyu unokanganisa sei kururama kwemuchina munzvimbo dzakasiyana dzekupisa?

 

Granite vs. Cast Iron uye Mineral Casting Beds: Kunzwisisa Thermal Expansion Coefficients uye Mhedzisiro Yadzo Pakururama Kwezvishandiso Zvemuchina

Kana zvasvika pakugadzirwa kwemibhedha yemidziyo yemuchina, zvinhu zvakaita segranite, simbi yakakandwa, uye mineral casting zvinowanzo shandiswa nekuda kwehunhu hwazvo hwakasiyana. Chimwe chinhu chakakosha chekufunga nezvacho pakusarudza zvinhu izvi i thermal expansion coefficient yazvo, kunyanya munzvimbo dzine tembiricha dzakasiyana. Musiyano uripo pakati pe thermal expansion coefficients pakati pe cast iron nemibhedha ye mineral casting unogona kukanganisa zvakanyanya kugadziriswa kwemashandisirwo emuchina munzvimbo dzakasiyana dzetembiricha.

Simbi yakakandwa, chinhu chekare chinoshandiswa pakugadzira maturusi emuchina, ine chiyero chekuwedzera kupisa chakakwira. Izvi zvinoreva kuti sezvo tembiricha dzichichinja-chinja, mibhedha yesimbi yakakandwa inowanzo wedzera uye kukotama, izvo zvinogona kutungamira kuchinjo dzehukuru hwechishandiso chemuchina. Kune rumwe rutivi, kukanda mineral, kunowanzo umbwa nezvinhu zvakaita se epoxy resin ne granite aggregates, kune chiyero chekuwedzera kupisa chakaderera zvichienzaniswa nesimbi yakakandwa. Hunhu uhwu hunobvumira mibhedha yekukanda mineral kuratidza shanduko shoma muhukuru nekuda kwekushanduka kwekushisa.

Mhedzisiro yemisiyano iyi inonyanya kukosha munzvimbo dzine dambudziko rekudzora tembiricha. Munzvimbo dzine tembiricha yakakwira, kuwedzera kwekushisa kwesimbi kunogona kukonzera kusarongeka kwehukuru hwechishandiso chemuchina, zvichikanganisa kunyatsoita kwayo uye mashandiro ayo. Kusiyana neizvi, mibhedha yekukanda mineral, ine kuwedzera kwayo kwekupisa kwakaderera, yakashongedzerwa zviri nani kuchengetedza kururama mumamiriro ezvinhu akadaro.

Kusiyana neizvi, munzvimbo dzine tembiricha yakaderera, kuwedzera kwemafuta emuchina wekugadzira mineral kunogona kukonzera chimiro chakaoma kana tichienzanisa nesimbi yakakandwa, zvichikanganisa mhinduro yemuchina uye hunhu hwekudzikisa simba. Kunzwisisa misiyano iyi kwakakosha kuti vagadziri nevashandisi vaite sarudzo dzakagadzirwa zvichienderana nemamiriro chaiwo etembiricha ayo muchina uchashanda nawo.

Mukupedzisa, chiyero chekuwedzera kwekupisa chinoita basa rakakosha mukusarudza zvinhu zvemibhedha yemidziyo yemuchina. Kunyange hazvo simbi yakakandwa yagara iri sarudzo yechinyakare, chiyero chekuwedzera kwekupisa kwemineral, chinowanzo sanganisira granite, chinopa zvakanakira mukuchengetedza kururama munzvimbo dzakasiyana dzekupisa. Nekufunga nezvezvinhu izvi, vagadziri nevashandisi vanogona kugadzirisa mashandiro uye hupenyu hwezvishandiso zvemuchina mumamiriro akasiyana-siyana ekushanda.
