Babban Bambanci Tsakanin Silicon Carbide da Tungsten Carbide Mechanical Seals
Kwatanta Halayen Jiki da Sinadarai
Silicon Carbide, wannan mahaɗin yana ɗauke da tsarin lu'ulu'u wanda ya ƙunshi ƙwayoyin silicon da carbon. Yana riƙe da ƙarfin zafi mara misaltuwa tsakanin kayan fuskar hatimi, mai tauri mai yawa wanda aka kimanta a 9.5 akan sikelin Mohs - na biyu bayan lu'u-lu'u - tare da kyakkyawan ƙarfin juriya ga tsatsa. SiC kuma kayan yumbu ne mara oxide wanda ke haifar da tauri mai yawa saboda amintaccen haɗin covalent da aka haɓaka a ko'ina cikin kayan.
Tungsten Carbide wani sinadari ne da aka yi shi da sinadarin Tungsten da Carbon. An ƙirƙira shi ta hanyar wani tsari da ake kira sintering wanda ke haifar da ƙimar abu mai tauri tsakanin 8.5-9 akan sikelin Mohs - mai tauri sosai don kusan duk wani amfani da aka yi masa amma ba mai tauri kamar SiC ba. Baya ga kasancewa mai kauri, WC yana nuna wani babban matakin tauri a kusa da zafi; duk da haka, bai da ƙarfi sosai idan aka kwatanta da Silicon Carbide.
Bambance-bambance a cikin Aiki a ƙarƙashin Yanayi daban-daban na Aiki
Idan aka kwatanta aikin hatimin silicon carbide (SiC) da tungsten carbide (WC) a ƙarƙashin yanayi daban-daban na aiki, yana da mahimmanci a tattauna martanin da suke bayarwa ga abubuwa kamar matsanancin zafin jiki, bambancin matsin lamba, kafofin watsa labarai masu lalata, da kuma ikonsu na jure yanayin gogewa.
Dangane da juriyar zafi, silicon carbide yana nuna kyakkyawan yanayin zafi kuma yana iya aiki yadda ya kamata a yanayin zafi mafi girma idan aka kwatanta da tungsten carbide. Wannan halayyar ta sa SiC ya zama zaɓi mafi kyau don aikace-aikace inda juriyar zafi mai yawa take da mahimmanci.
Akasin haka, idan ana la'akari da juriyar matsin lamba, tungsten carbide yana da fa'ida ta musamman fiye da silicon carbide. Tsarinsa mai kauri yana ba shi damar jure yanayin matsin lamba mai tsanani fiye da SiC. Saboda haka, hatimin WC sun fi dacewa da aikace-aikacen da ke da matsin lamba mai yawa.
Dangane da hanyoyin aiki da waɗannan hatimin ke fuskanta, juriyar lalata ta zama wani muhimmin ma'auni don kimantawa. Silicon carbide ya fi ƙarfin tungsten carbide wajen tsayayya da maganin acidic da alkaline saboda yanayinsa na rashin aiki a sinadarai. Saboda haka, ana fifita hatimin SiC a masana'antu da ke fama da ruwa ko iskar gas mai ƙarfi.
Juriyar lalacewa tsakanin waɗannan nau'ikan hatimi guda biyu tana komawa baya don maye gurbin tungsten carbide saboda taurinsa na asali, wanda hakan ke sa ya fi dacewa da yanayin gogewa a tsawon lokacin amfani.
Kwatanta Farashi
Yawanci, farashin farko na hatimin tungsten carbide na iya zama mafi girma fiye da na silicon carbide saboda kyawun juriyarsa ga lalacewa da kuma taurinsa. Duk da haka, yana da mahimmanci a yi la'akari da ba kawai farashin farko ba, har ma da kuɗin aiki na dogon lokaci.
Duk da cewa hatimin tungsten carbide na iya buƙatar babban jari na farko, tsawon rayuwarsu da ingancinsu na iya rage wannan kuɗin farko akan lokaci. A gefe guda kuma, hatimin silicon carbide gabaɗaya suna da rahusa a gaba wanda hakan ya sa su zama zaɓi mai kyau ga 'yan kasuwa masu la'akari da kasafin kuɗi. Duk da haka, idan aka yi la'akari da ƙarancin juriyar lalacewa a wasu yanayi, suna iya buƙatar maye gurbinsu akai-akai ko gyara wanda zai haifar da tsada mai yawa na dogon lokaci.
Bambance-bambance a cikin Dorewa da Juriyar Sawa
Hatimin silicon Carbide yana da tauri mai ban mamaki tare da yawan jurewar zafi. Wannan haɗin yana sa su zama marasa sauƙin sawa saboda gogayya, yana rage damarsu ta nakasa koda a cikin mawuyacin yanayi na aiki. Bugu da ƙari, juriyarsu ga tsatsa ta sinadarai yana ƙara haɓaka juriyarsu gaba ɗaya.
A gefe guda kuma, hatimin injina na Tungsten Carbide suna ba da ƙarfi da tauri mara misaltuwa, wanda ke taimaka musu jure matsin lamba mai yawa na tsawon lokaci. Ƙarfinsu yana tabbatar da aiki mai dorewa koda lokacin da ake fuskantar yanayi mai wahala, wanda ke ƙara juriyar lalacewa sosai.
Duk kayan suna da juriya ga faɗaɗa zafi; duk da haka, Silicon Carbide yana nuna ɗan juriyar girgizar zafi idan aka kwatanta da Tungsten Carbide. Wannan yana nufin cewa hatimin SiC ba su da yuwuwar fashewa ko lalacewa idan aka fallasa su ga canje-canjen zafin jiki cikin sauri - wani abu da ke ba da gudummawa mai kyau dangane da dorewa.
Yadda Ake Zaɓa Tsakanin Silicon Carbide da Tungsten Carbide Mechanical Seals
Ainihin, yana da mahimmanci a yi la'akari da yanayin da hatimin zai yi aiki. Wannan yana la'akari da abubuwa kamar yanayin ruwan da ke cikin tsarin, yanayin zafin jiki, matakan matsin lamba, da kuma yiwuwar duk wani abu mai lalata. Ana ɗaukar WC sosai a matsayin mai ƙarfi da juriya ga lalacewa. Saboda haka, ana iya fifita shi a cikin muhallin da ke buƙatar tauri daga gogewa ko matsin lamba mai tsanani.
A gefe guda kuma, SiC yana da kyakkyawan juriya ga girgizar zafi da tsatsa wanda hakan ya sa ya dace da aikace-aikace inda ake tsammanin canje-canje masu tsanani a zafin jiki ko kuma akwai ruwa mai lalata sosai. Ƙarfin halayensa masu haɗaka kuma yana nuna ƙarancin amfani da makamashi, don haka yana sa hatimin SiC ya dace da ayyukan da ke da saurin amsawa ga makamashi.
Bugu da ƙari, bai kamata a yi watsi da la'akari da kuɗi ba yayin yin wannan zaɓin; yayin da WC ke da ƙarfin hali da juriya ga lalacewa, yana da tsada fiye da takwarorin SiC. Saboda haka, idan ƙuntatawa a kasafin kuɗi sune abubuwan da ke iyakancewa, zaɓar SiC na iya zama mafita mai yiwuwa muddin babu yanayi mai tsanani/mai illa ga aiki.
Abu mafi mahimmanci shine amincin alamar ku ko ƙwarewar ku ta baya tare da hatimin silicon carbide na inji ko hatimin tungsten carbide na inji. Wasu kamfanoni suna ci gaba da amfani da su dangane da bayanan tarihi ko gogewar aiki na baya na amfani da nau'in ɗaya fiye da wani wanda ya yi kama da mai kyau daga mahangar aminci.
A ƙarshe
A ƙarshe, hatimin injina na Silicon Carbide da Tungsten Carbide mafita ne daban-daban don sarrafa aikace-aikacen injina. Duk da cewa Silicon Carbide yana ba da juriya mai ban sha'awa ga zafi da kwanciyar hankali na sinadarai, Tungsten Carbide sananne ne saboda ƙarfinsa da ƙarfinsa a cikin mawuyacin yanayi. Zaɓin da za ku yi tsakanin waɗannan kayan biyu ya kamata ya kasance bisa ga takamaiman buƙatunku da buƙatun aikace-aikacen; babu mafita ta duniya baki ɗaya. Ƙungiyar ƙwararrunmu ta XYZ Inc. ta yi fice wajen samar da mafita masu daidaitawa don daidaita buƙatun masana'antu daban-daban da inganci.
Yanzu kun gano bambance-bambancen da ke tsakanin hatimin silicon Carbide da na Tungsten Carbide, amma a bayyane yake cewa fahimtar wacce ta fi dacewa da kayan aikinku da ayyukanku na iya zama ƙalubale. Sa'a tana fifita masu ilimi! Don haka tabbatar kun samar wa kanku da shawarwari masu mahimmanci waɗanda suka dace da takamaiman masana'antar ku.
