Sanya bututun yumbu na Silicon carbide Resistant
Silicon carbide yumbu: Taurin Moh shine 9.0 ~ 9.2, tare da kyakkyawan juriya ga yashwa da lalata, kyakkyawan juriya-juriya da anti-oxidation. Yana da ƙarfi sau 4 zuwa 5 fiye da nitride bonded silicon carbide. Rayuwar sabis shine sau 7 zuwa 10 fiye da kayan alumina. MOR na RBSiC shine sau 5 zuwa 7 na SNBSC, ana iya amfani dashi don ƙarin sifofi masu rikitarwa.
Silicon carbide sa juriya, an hada shi daga silicon carbide da carbon a high zafin jiki, nasa ne da wani irin silicon carbide samfurin.The silicon carbide lalacewa juriya sassa ana amfani da ko'ina a cikin ma'adinai, ore crushing, nunawa da kuma kai na high lalacewa, high m lalata. ruwaye, kuma sosai dace da inji kayayyakin da high madaidaici da sealing bukatun, irin su high matsa lamba famfo, Magnetic famfo etc.Is wani sabon irin lalacewa juriya material.Reaction- bonded silicon carbide lalacewa juriya bushing yana da halaye na high taurin, high high. sa juriya, tasiri juriya, high zafin jiki juriya, acid da alkali lalata juriya da sauransu, da kuma ainihin sabis rayuwa ne fiye da 6 sau cewa na polyurethane.It ne musamman dace da aiki na rarrabuwa, taro da dehydration na karfi abrasive da kuma m-grained kayan, da aka samu nasarar amfani a da yawa ma'adinai.Our kamfanin ne mai sana'a silicon carbide sa juriya yumbu kayayyakin maroki, taurin na biyu kawai zuwa lu'u-lu'u, tare da high lalacewa juriya, dogon sabis rayuwa features.The lalacewa juriya bututu da gwiwar hannu da samar. tare da silicon carbide sa juriya rufi, da yumbu rufi kauri ne 6-35mm, da tsarin ne don shigar da riga sintered yumbu tube a cikin daidai caliber karfe tube, tare da manne a tsakiyar.Wear juriya yumbu bututu suna da wadannan kaddarorin idan aka kwatanta da na baya soma simintin-dutse bututu, sa-resistant gami simintin karfe bututu da yumbu hada bututu.
Reaction bonded silicon carbide (RBSC) yana da kyakkyawan yanayin juriya, kyawawan kaddarorin a yanayin zafi mai tsayi, kyakkyawan yazawa da juriya, ana iya amfani da waɗannan kaddarorin a aikace-aikace iri-iri kamar su bututun bututu, gwiwar hannu yumbu, fesa nozzles, harbin bututun iska da kuma abubuwan hydrocyclone.
Lining na ZPC sun yi nisa da tiled tile da ƙarfe. ZPC silicon carbide tukwane sune juriya na girgiza zafin zafi da juriya na abrasion wanda ke haifar da tsawaita lokacin gudu da raguwar lokaci.
A dauki bonded silicion carbide yumbu (RBSIC) ne manufa lalacewa resistant abu, wanda shi ne musamman dace da karfi abrasive, m barbashi, rarrabuwa, maida hankali, dehydration da sauran ayyuka. Saboda abubuwan da ke sama, daRBSiC / SiSiC silicon carbide liner gwiwar hannu / bututu mai layizai iya kare sashi yadda ya kamata daga babban lalacewa da zafin jiki don tsawaita rayuwar sabis na kayan aiki.
