Bututun yumbu mai jure silicon carbide
Yumburin silicon carbide: Taurin Moh yana da ƙarfi 9.0~9.2, yana da juriya mai kyau ga zaizayewa da tsatsa, juriya mai kyau ga gogewa da hana iskar shaka. Yana da ƙarfi sau 4 zuwa 5 fiye da nitride bonded silicon carbide. Rayuwar sabis ɗin ta fi ta alumina sau 7 zuwa 10. MOR na RBSiC ya fi na SNBSC sau 5 zuwa 7, ana iya amfani da shi don siffofi masu rikitarwa.
Juriyar lalacewa ta silicon carbide, an haɗa ta ne daga silicon carbide da carbon a zafin jiki mai yawa, tana cikin wani nau'in samfurin silicon carbide. Ana amfani da sassan juriyar lalacewa ta silicon carbide sosai a cikin haƙar ma'adinai, niƙa ma'adinai, tantancewa da jigilar lalacewa mai yawa, ruwa mai lalata, kuma ya dace da samfuran injiniya tare da babban daidaito da buƙatun rufewa, kamar famfon matsin lamba mai yawa, famfon maganadisu da sauransu. Sabon nau'in kayan juriya ne na lalacewa. Bushing mai ɗaurewa da silicon carbide yana da halaye na babban tauri, juriya mai ƙarfi, juriyar tasiri, juriyar zafi mai yawa, juriyar lalata acid da alkali da sauransu, kuma ainihin rayuwar sabis ɗin ta fi sau 6 fiye da na polyurethane. Ya dace musamman don aikin rarrabuwa, tattarawa da bushewar kayan abrasive masu ƙarfi da ƙazanta, an yi amfani da shi cikin nasara a cikin ma'adanai da yawa. Kamfaninmu ƙwararren mai samar da samfuran yumbu ne mai juriyar lalacewa ta silicon carbide, mai tauri na biyu bayan lu'u-lu'u, tare da juriya mai ƙarfi, fasalulluka na tsawon rai. Bututun juriya na lalacewa da gwiwar hannu wanda aka samar da layin juriya na silicon carbide, kauri na rufin yumbu shine 6-35mm, tsarin shine don shigar da shi. Bututun yumbu da aka riga aka yi wa siminti a cikin bututun ƙarfe mai daidai, tare da manne a tsakiya. Bututun yumbu masu juriya ga lalacewa suna da waɗannan halaye idan aka kwatanta da bututun dutse da aka yi amfani da su a baya, bututun ƙarfe mai jure lalacewa da bututun yumbu masu haɗaka.
Carbide mai haɗin kai na silicon (RBSC) yana da kyakkyawan juriya ga lalacewa, yana da kyawawan halaye a yanayin zafi mai yawa, yana da kyau yashewa da juriya ga abrasion. Ana iya amfani da waɗannan kaddarorin a aikace-aikace iri-iri kamar bututun bututu, gwiwar hannu ta yumbu, bututun feshi, bututun fashewa da abubuwan da ke cikin hydrocyclone.
Layin ZPC ya fi na roba da tayal da ƙarfe nesa. Yumburan ZPC silicon carbide suna da juriya ga girgizar zafi da kuma tsagewa wanda ke haifar da tsawaita lokacin aiki da kuma rage lokacin aiki.
Yumbu mai ɗaure silicion carbide (RBSIC) abu ne mai kyau wanda ke jure lalacewa, wanda ya dace musamman don ƙaƙƙarfan barbashi masu ƙarfi, masu kauri, rarrabuwa, yawan aiki, bushewar ruwa da sauran ayyuka. Saboda halayen da ke sama,RBSiC / SiSiC silicon carbide liner gwiwar hannu / bututun layizai iya kare ɓangaren yadda ya kamata daga lalacewa da zafin jiki mai yawa don tsawaita rayuwar kayan aiki.
