Umuyoboro wo Kurinda Karuboni ya Silicon
Dutanga serivisi zitanga umusaruro mwizaImiyoboro yo kurinda Silicon Carbide (SiC)Yakozwe kugira ngo ikore neza mu nganda zikora cyane, harimo ubushyuhe bwinshi cyane, ingese ikomeye ya shimi, kwangirika kwa mashini no gushyuha kenshi. Ikoreshwa cyane mu byuma, gutunganya ubushyuhe, gutwika ceramic, gukora ikoranabuhanga rya shimi no mu nganda zikoresha ibyuma bishyuha cyane, imiyoboro yacu ya SiC ikora nk'amaboko akomeye yo kurinda thermocouples, imiyoboro y'umuriro, ibice byo kohereza ubushyuhe n'ibirindiro by'itanura, byongerera igihe cyo gukoresha ibikoresho no kugabanya ikiguzi cyo kubisana gisanzwe.
Dutanga amanota atatu y’ingenzi ajyanye n’ibikenewe mu buryo butandukanye:SiC ifite Reaction-Bonded (RBSiC), SiC ifite Recrystallized (RSiC) na SiC ifite Silicon Nitride-Bonded (NBSiC).Buri rwego rufite ibyiza byihariye mu mikorere, kandi dutanga serivisi zose zijyanye no gukora ibikoresho byihariye kugira ngo bihuze n'ingano yawe, imiterere n'imiterere y'aho ukorera.
1. Serivisi yo gukora ibintu byihariye | OEM na ODM birahari
Dusobanukiwe neza ko abakiriya b'inganda bafite ibyo bakeneye byihariye ku bunini, imiterere, uburyo bwo gushyiraho no gukora. Dutanga ibisubizo byuzuye byihariye ku miyoboro yo kurinda SiC, bikubiyemo imiterere y'ibicuruzwa, guteza imbere ingero, gukora ibintu byinshi no kugenzura neza ubuziranenge. Itsinda ryacu rya tekiniki rizagusaba urwego rwa SiC rukwiye cyane hashingiwe ku bushyuhe bw'akazi kawe, ubwoko buringaniye, igitutu n'aho ushyira kugira ngo umushinga wawe urusheho gukora neza kandi ugire umusaruro mwiza.
2. Ingano yo Guhindura
(1) Guhindura ingano:Umurambararo wo hanze uri hagati ya Φ12mm na Φ300mm, uburebure bumwe bugera kuri 3000mm, ubugari bw'urukuta bushobora guhindurwa kuva kuri 3mm kugeza kuri 30mm, bufite ubushobozi bwo kwihanganira ibintu mu buryo buhamye (± 0.5mm kugeza ± 1.0mm) hashingiwe ku bipimo by'ibicuruzwa n'ibisabwa mu buryo bwo kubitunganya kugira ngo harebwe ko bihuye neza n'ibikoresho by'abakiriya.
(2) Imiterere n'Iherezo ry'Uburyo bwo Guhindura Imiterere:Dushyigikire impera ifunze, impera ifunguye, impera ifite imigozi (imigozi isanzwe n'idasanzwe), imiyoboro y'imbere n'inyuma, imiyoboro y'impeta ifunga, imyobo yo gushyiramo, n'indi miterere y'imiterere. Dutanga kandi ibikoresho byihariye bifite imiterere yihariye, birimo imiyoboro ifite ubugari bwa 45°/90°, imiyoboro igabanya, imigozi, n'inyubako zifite amababa ku buryo bwihariye bwo kuyishyiraho no kuyikoresha.
(3) Guhindura Imikorere:Hindura imiterere y'ibikoresho, uburyo bitwara ubushyuhe, imbaraga zo gukanda, n'ibipimo byo kurwanya ingese hakurikijwe imiterere yihariye y'akazi, ongera uburyo ibikoresho bikoreshwa kugira ngo bihuze n'ibidukikije bidasanzwe, kandi wongere ubuzima bw'imikorere n'imikorere ihamye.
(4) Guhindura Uburyo:Guhinduranya ibintu hagati ya RBSiC, RSiC, na NBSiC hashingiwe ku buryo abakiriya bakoresha; ku bice by'imiterere bigoye, dushyira imbere uburyo bwo gusinya imiterere y'imashini kugira ngo tugabanye ikiguzi cyo gutunganya no kwemeza ko imiterere y'imashini ikora neza.
Imiyoboro yo kurinda Silikoni Nitride-Bonded SiC (NBSiC)
Imiyoboro ya NBSiC ikorwa mu ifu ya SiC na silikoni ifite isuku nyinshi, ikorwa hakoreshejwe extrusion cyangwa grouting, hanyuma igashyirwamo nitride kuri 1350-1500°C mu kirere cya azote. Kristale za silikoni zifata neza uduce twa SiC, bigatuma habaho imvange ikomeye ifite ubushobozi bwo kurwanya ingese mu byuma bishongeshejwe kandi idafatana, ikaba nziza cyane mu gihe cyo gushongesha ibyuma bidakoresha feri.
1. Imikorere y'ingenzi n'ibiranga
(1) Ubushyuhe ntarengwa bwo gukora bugera kuri 1500°C, bufite imikorere ihamye mu byuma bishongeshejwe n'ahantu hashyushye cyane hashobora kwangirika
(2) Ubudahangarwa bwiza na aluminiyumu ishongeshejwe, zinki, umuringa, n'ibindi bikoresho by'icyuma bidakoresha feri, nta gufatana n'ibyuma bishongeshejwe kandi nta mwanda w'amazi y'icyuma wanduye.
(3) Ingufu nyinshi z'ubushyuhe, zituma habaho uburyo bwo kumva ubushyuhe vuba no kohereza ubushyuhe neza kugira ngo hagenzurwe neza ubushyuhe
(4) Ifite imbaraga nziza za mekanike kandi irwanya ubushyuhe, ikwiriye gukoreshwa igihe kirekire mu gushonga no gutwika ibyuma hakoreshejwe ibyuma
(5) Ifite imiterere mike kandi ikungahaye, ikura neza icyuma gishongeshejwe, imyuka ishaje n'ibyuka byangiza kugira ngo irinde ibice by'imbere
2. Porogaramu zisabwa
Imiyoboro yo kurinda ya NBSiC yagenewe by'umwihariko inganda zikora ibyuma, ahanini ikoreshwa mu miyoboro yo gupima ubushyuhe bw'icyuma gishongeshejwe, imiyoboro yo kuzamura, amaboko yo kurinda thermocouple yo mu ifuru ya aluminium/copper/zinc, ibikoresho birinda pisine ishongeshejwe, n'ibikoresho byo gucukura bidasibangana. Ni igisubizo cyiza cyane ku bijyanye no kwirinda ingese no kudafatana kw'icyuma gishongeshejwe.
Imiyoboro yo kurinda SiC (RBSiC) ifite Reaction-Bonded
Imiyoboro ya RBSiC ikorwa binyuze mu ikoranabuhanga rigezweho ryo kwinjira no gusya ibintu, hakoreshejwe ifu ya SiC na karuboni isukuye cyane. Silikoni ishongeshejwe yinjira mu mubiri w’icyatsi kibisi hanyuma igakora imiterere ikomeye ifatanye, ifite siliconi idafite 8-15%. Iyi nzira ituma habaho imiterere ya hafi ifite ubugari buri munsi ya 1%, itanga umusaruro uhendutse kandi ikaba nziza ku musaruro munini w’inganda.
1. Imikorere y'ingenzi n'ibiranga
(1) Ubushyuhe ntarengwa bwo gukora bugera kuri 1400°C, hamwe n'imikorere ihamye y'igihe kirekire ku bushyuhe bwinshi buhoraho
(2) Ubucucike bwinshi, imbaraga nziza za mekanike, no kudakora neza ku ngaruka za mekanike ndetse no kwangirika gake
(3) Ihendutse cyane ugereranije n'izindi formulaire za SiC, zikwiriye gukoreshwa mu nganda nini
(4) Ifite ubushobozi bwo gukora neza cyane, bigatuma habaho ibice bifite ishusho igoye bitabaye ngombwa ko bitunganywa cyane
(5) Ubudahangarwa bwiza ku kwangirika kw'ibinyabutabire bisanzwe, harimo n'ikirere cy'inganda gifite aside na alkaline
2. Porogaramu zisabwa
Imiyoboro yo kurinda RBSiC ikoreshwa cyane mu miyoboro y’imirasire y’itanura, imishumi isanzwe yo kurinda thermocouple, imiyoboro yo gusukura, imiyoboro yo gushyushya, hamwe n’ibice rusange by’itanura rikoresha ubushyuhe bwinshi. Ni amahitamo meza cyane mu gukoresha isaba imikorere iboneye no kugenzura ikiguzi, nta cyifuzo cy’ubushyuhe buri hejuru ya 1400°C.
Imiyoboro yo kurinda SiC (RSiC) yongerewe gukoreshwa
Imiyoboro ya RSiC iracukurwa ku bushyuhe bwinshi cyane (2100-2450°C) nta gice cya kabiri cyo gufatanya, kigizwe no guhumeka mu buryo butaziguye no guhumeka kw'uduce twa α-SiC dufite isuku nyinshi. Iyi miterere y'ubutare isukuye ituma nta mwandu wanduzwa, bigatuma iba amahitamo meza ku hantu hakorerwa ubushyuhe bwinshi cyane n'ahantu hakorerwa ubuziranenge bwinshi.
1. Imikorere y'ingenzi n'ibiranga
(1) Irwanya ubushyuhe bwinshi cyane, ifite ubushyuhe bwinshi buhoraho bugera kuri 1800°C, ikwiriye imikorere ikorerwa mu gihe cy'ubushyuhe bwinshi cyane
(2) 100% crystalline phase ya SiC, nta mwanda uhumanya, ni nziza cyane mu gutunganya ubushyuhe bwinshi no mu itanura rigenzurwa n'ikirere.
(3) Ubudahangarwa budasanzwe bw'ubushyuhe, bushobora kwihanganira impinduka zihuse z'ubushyuhe nta gucika cyangwa kwangirika
(4) Ubushyuhe bwinshi butuma ibintu bihora bihindagurika kandi bigakomeza neza mu bushyuhe bwinshi, bigakomeza kuba imiterere myiza mu gihe cy'ubushyuhe bwinshi cyane igihe kirekire.
(5) Ubudahangarwa bukomeye ku isuri n'ingufu ziterwa n'imyuka, bikwiranye n'ahantu hakomeye ho mu itanura hafite umuvuduko mwinshi w'amazi n'ingaruka z'udukoko.
