Bututun Ciyar da yumbu Layin Wye & Tees
Bututun wyes da bututun tees
Wyes na bututu suna kama da tees ɗin bututu.Bambancin kawai shi ne cewa layin reshe yana da kusurwa don rage rikici wanda zai iya kawo cikas ga magudanar ruwa.Haɗin bututu yawanci yana a kusurwa 45-digiri maimakon kwana 90-digiri na yau da kullun.Idan reshe ya juya a ƙarshen ya kasance daidai da layi, dacewa da bututun ya zama "tee wye".

Halayen yumbu hade bututu
Kyakkyawan juriya na lalacewa
Bututun yumbu mai hade saboda corundum yumbu (a-AL2O3), taurin Mohs na 9.0 yayi daidai da fiye da HRC90.Saboda haka, yana da babban juriya na lalacewa ga kafofin watsa labaru masu lalata da masana'antu kamar ƙarfe, wutar lantarki, ma'adinai, da gawayi.An tabbatar da aikin masana'antu cewa rayuwar sa ta kai sau goma ko ma sau goma fiye da taurin karfe.
Ƙananan juriya aiki
SHS yumbu composite bututu baya kama da layi mai karkace akan saman ciki na bututun karfe maras sumul saboda saman ciki yana da santsi kuma baya lalacewa.An gwada ƙaƙƙarfan saman ciki da bayyanannun halayen juriya na ruwa na sassan gwajin da suka dace.Santsi na ciki ya fi na kowane bututun ƙarfe.Matsakaicin madaidaicin ja ya kasance 0.0193, wanda ya ɗan yi ƙasa da bututu maras sumul.Sabili da haka, bututu yana da halaye na ƙananan juriya na gudu kuma yana iya rage farashin aiki.
Lalata, anti-scaling
Tun da karfe yumbu Layer ne (a-AL2O3), shi ne tsaka tsaki hali.Saboda haka, yana da juriya ga acid da alkali da lalata ruwan teku, kuma yana da abubuwan da ba su da ƙarfi.
Juriyar yanayin zafi da juriya na zafi
Saboda yumburan corundum (a-AL2O3), tsari ne mai tsayin daka guda.Sabili da haka, bututun da aka haɗa zai iya aiki akai-akai a cikin kewayon zafin jiki na dogon lokaci na -50--700 ° C.Material faɗaɗa madaidaici na 6-8 × 10-6/0C, kusan 1/2 na bututun ƙarfe.Kayan yana da kyakkyawan kwanciyar hankali na thermal.
Farashin aikin yana da ƙasa
Bututun da aka haɗa yumbu suna da nauyi da araha.Yana da 50% sauƙi fiye da bututun dutsen da aka jefa tare da diamita iri ɗaya na ciki;yana da 20-30% mai sauƙi fiye da bututu mai jure lalacewa, kuma yana da juriya mai kyau da juriya na lalata saboda tsawon rayuwar sa, don haka yana tallafawa farashin hanger, farashin sufuri, kuɗin shigarwa, da Rage farashin aiki.Idan aka kwatanta kasafin kuɗin aikin na cibiyar ƙira da rukunin gine-gine tare da ainihin aikin, farashin aikin yana daidai da dutsen simintin gyare-gyare.Idan aka kwatanta da bututun gami mai jure lalacewa, an rage farashin aikin da kusan kashi 20%.
Sauƙi shigarwa da ginawa
Saboda sauƙin nauyinsa da kyakkyawan aikin walda.Sabili da haka, ana iya ɗaukar walda, flanges, haɗakarwa mai sauri, da dai sauransu, kuma ginawa da shigarwa sun dace, kuma ana iya rage farashin shigarwa.
Aikace-aikace
Hakanan za'a iya amfani da madaidaicin bututun yumbu a cikin sassan famfo na kankare saboda fa'idodin su, musamman ƙarancin nauyi, wanda ke taimakawa wajen guje wa cunkoso yayin jigilar siminti.
