Ƙarfafa Na Musamman Tare da Silicon Carbide Tube

Silicon carbide tubes sanannen zaɓi ne a cikin saitunan masana'antu saboda fitattun kaddarorin su kamar ƙarfi, thermal watsin da juriya da lalata da lalacewa.

Silica mai siliki kai tsaye yana da taurin kwatankwacin lu'u-lu'u, kuma yana iya jure matsanancin yanayin zafi, lalacewar sinadaran da damuwa na inji – halayen da ke sa su dace da samar da wutar lantarki, sarrafa sinadarai da aikace-aikacen sararin samaniya.

Babban Juriya na Zazzabi

Silicon Carbide abu ne mai matuƙar wahala da juriya. Tare da na biyu kawai zuwa lu'u-lu'u da cubic boron nitride a cikin taurin, silicon carbide yana ba da ingantaccen juriya ko da a cikin yanayi mara kyau. Bugu da kari, wannan yumbu yana alfahari da kyakkyawan juriya na zafin jiki da juriya da iskar shaka da lalata.

Halayen Silicon carbide sun sa ya dace musamman don aikace-aikacen da ke aiki a ƙarƙashin matsanancin yanayin muhalli, ciki har da samar da wutar lantarki da hanyoyin masana'antu. Bugu da kari, dorewar sa ya haɗu da ingantaccen makamashi da rage sawun carbon, yin shi zaɓi mai tasiri ga kamfanoni da ke mayar da hankali kan dorewa da alhakin muhalli.

SiC na musamman na tetrahedral na silicon da carbon atom ɗin da ke daure sosai a cikin lattice ɗin sa na kristal yana ba da keɓancewar yanayin zafi.. Wannan abu yana canja wurin makamashin thermal har zuwa 50% mafi kyau fiye da graphite kuma 10% mafi kyau fiye da yawancin karafa, sauƙaƙe ingantaccen sarrafa zafi a cikin yanayin da ake buƙata. Bugu da kari, Ƙarƙashin ƙarfinsa na faɗaɗa thermal da juriya ga zafin zafi yana ƙara ƙara ƙarfinsa, yin SiC kyakkyawan zaɓi don tanderun masana'antu ko abubuwan haɗin gwiwa kamar masu kare thermocouple.

Low Coefficient of thermal Expansion

Silicon Carbide Tubes suna da ƙarfi, abubuwa masu ɗorewa tare da tsawon rayuwa wanda ya sa su zama kadara masu kima a cikin saitunan masana'antu. Wadannan bututu na iya jure yanayin zafi mai zafi, m yanayi, sinadarai masu lalata da kiyaye ƙarfin injina tsawon rayuwarsu – sanya su kadara masu kima a yawancin saitunan masana'antu.

Ƙaramar haɓakar haɓaka haɓakar thermal suna ba da damar wannan aikin, ma'ana suna fadada kuma suna yin kwangila kadan a yanayin zafi mai zafi – yin su cikakke don kayan aiki mai mahimmanci da kayan aikin thermostructural kamar tanderu, wutar lantarki da tsarin jujjuya makamashi.

Mafi girman taurinsu, taurin kai, da thermal conductivity yin yumbu kyakkyawan zaɓi na kayan abu don abubuwan da aka gyara kamar abrasives da ƙafafun niƙa, sassan yumbu, yankan kayan aikin, deoxidizers don tsarin deoxidization na ƙarfe da garkuwar harsashi saboda ƙarfin ballistic da ƙarfin ƙarfinsu..

Babban Ƙarfin Injini

Silicon Carbide abu ne mai wahala na musamman, m abu iya jure tsanani inji danniya. Karya taurinsa yayi daraja 6.8 MPa m0.5, sanya shi daya daga cikin abubuwa mafi wuya da mutum ya sani. Bugu da kari, Ƙarfin sa na sassauci shine 490 MPa wanda ke nuna juriya mai ƙarfi akan lankwasawa.

Silicon carbide na keɓaɓɓen kayan aikin injiniya sun sa ya zama kyakkyawan zaɓi na kayan aiki don amfani a masana'antar sarrafa zafin jiki kamar narke ƙarfe da masana'antar sutura.. Silicon carbide na iya zama mai maye gurbin karafa na gargajiya a cikin tanderun masana'antu da masu kare ma'auratan thermal, yana nuna matuƙar karko akan lokaci.

Komai hanyar samar da ita – babban SiC, amsawa bonded SiC ko YSiC) duk nau'ikan yumbu na silicon carbide yana nuna kyawawan sinadarai da kaddarorin jiki a ƙarƙashin matsanancin yanayin amfani na ƙarshe. Ƙarin fahimta game da manyan nau'ikan yumbura na SiC don jin daɗin ƙarfinsu da fa'idodinsu.

Babban Juriya ga Lalacewa

Silicon carbide yana tsaye a matsayin ɗaya daga cikin manyan abubuwan yumbu na duniya, sauran juriya ga matsanancin yanayin zafi, sunadarai da matsalolin inji. Wannan abin al'ajabi na injiniya yana taka muhimmiyar rawa a cikin ayyukan masana'antu tun daga narke karafa da samar da wutar lantarki zuwa sarrafa sinadarai.

Silicon carbide kai tsaye yana ba da fa'idodi da yawa, kamar taurin, ƙarfin inji da kuma thermal conductivity. A matsayin kayan yumbu kuma yana nuna rashin kuzarin sinadarai da juriya ga tasiri, abrasion da lalata.

Hexoloy SE abu ne mai siffa mai siliki wanda za'a iya samarwa ta hanyar extrusion (bututu) ko sanyi isostatic latsa (faranti da tubalan). Da zarar an gama, Ana iya haɗa waɗannan sassan don haɗawa cikin samfurin da aka kora tare da girman hatsi iri ɗaya, yawa, da sarrafa girma.

Hexoloy SE yana da juriyar lalata mara misaltuwa, yana dacewa da kusan dukkanin acid kamar hydrochloric, sulfuric da nitric acid. Saboda haka, Wannan ƙarfe yana yin kyakkyawan zaɓi don harsashi da masu musayar zafi da aka yi amfani da su a cikin mahallin sinadarai da kuma bututun firikwensin zafin jiki a cikin buƙatun murhu ko muhallin kiln..
