Mundima yemazuva ano yeindasitiri, zvigadziko zvesimbi zvesilicon carbide zvinozivikanwa se "zvombo zveindasitiri" uye zvave chinhu chakakosha munzvimbo dzakaoma nekuda kwesimba razvo guru, kuramba kupisa kwakanyanya, uye kuramba ngura. Asi chisingazivikanwe nevanhu vazhinji ndechekuti mhuri yesimbi yesilicon carbide ine nhengo dzakawanda, uye maitiro akasiyana ekugadzirira anovapa "hunhu" hwakasiyana. Nhasi tichataura nezvemhando dzakajairika dzezviumbwa zvesimbi zvesilicon carbideuye kuratidza mabhenefiti akasiyana ereaction sintered silicon carbide, tekinoroji huru yemabhizinesi.
1、 "Vana Vatatu" veSilicon Carbide Ceramics
Kushanda kwesimbi dzesilicon carbide kunonyanya kuenderana nekugadzirwa kwadzo. Parizvino kune mhando nhatu huru:
1. Silikoni kabhadhidhi isina kumanikidzwa
Nekuumba zvakananga upfu hwesilicon carbide kuburikidza nekupisa kwakanyanya, ine huremu hwakawanda uye kuomarara kwakasimba, asi tembiricha yekugadzirira yakanyanya uye mutengo unodhura, zvichiita kuti ive yakakodzera zvikamu zvidiki zvine kunyatsoita zvinodiwa zvakanyanya.
2. Silicon carbide yakapfava inopisa
Yakagadzirwa pasi pekupisa kwakanyanya uye kumanikidzwa kwakanyanya, ine chimiro chakakora uye inodzivirira kupfeka zvakanaka, asi michina yacho yakaoma uye yakaoma kugadzira zvikamu zvakakura kana zvakaoma, zvichideredza huwandu hwekushandiswa kwayo.
3. Reaction sintered silicon carbide (RBSiC)
Nekuisa zvinhu zvesilicon muzvinhu zvakagadziriswa zvesilicon carbide uye kushandisa maitiro emakemikari kuzadza mipata yezvinhu, tembiricha yemaitiro yakaderera, kutenderera kwacho kupfupi, uye zvikamu zvikuru uye zvisina kurongeka zvinogona kugadzirwa nenzira inochinjika. Kubudirira kwemutengo kwakanaka kwazvo, zvichiita kuti ive mhando yesilicon carbide inoshandiswa zvakanyanya mumunda wemaindasitiri.
2, Sei reaction sintered silicon carbide ichinyanya kufarirwa?
Sechinhu chikuru chebhizinesi, maitiro akasiyana ekuita reaction sintered silicon carbide (RBSiC) anoita kuti ive "chinhu chinodiwa" mumaindasitiri mazhinji. Zvakanakira zvayo zvinogona kupfupikiswa nemashoko matatu akakosha:
1. Yakasimba uye inogara kwenguva refu
Maitiro ekupisa kwechinhu ichi anoumba "chimiro chinosungana" mukati mechinhu chacho, chinogona kuramba tembiricha yepamusoro ye1350 ℃ uye chinodzivirira kupfekwa zvakanyanya uye chinodzivirira kupisa kwakanyanya - hachikuvadzi nyore munzvimbo dzakapfekwa zvakanyanya uye tembiricha yepamusoro, kunyanya yakakodzera mamiriro ekupisa kwakanyanya senge zvishandiso zvechoto uye zvinopisa.
2. Enda kuhondo nemidziyo mwenje
Zvichienzaniswa nezvinhu zvesimbi zvechinyakare, reaction sintered silicon carbide ine density yakaderera asi inogona kupa simba rakafanana, zvichideredza zvakanyanya kushandiswa kwesimba remidziyo. Semuenzaniso, muindasitiri ye photovoltaic, zvikamu zve silicon carbide zvakareruka zvinogona kuvandudza zvakanyanya kushanda zvakanaka kwezvitofu zve crystal imwe chete.
3. Inochinjika uye inokwanisa kushandiswa zvakasiyana-siyana
Ingave matireyi e semiconductor ane dhayamita inodarika mamita maviri, ma nozzles akaomarara, mhete dzekuvhara, kana zvikamu zvakagadzirwa zvakagadzirwa zvine maumbirwo akasiyana, tekinoroji ye reaction sintering inogona kudzora chimiro nehukuru nemazvo, ichigadzirisa dambudziko rekugadzira "rakakura uye rakarurama".
3, 'Simba risingaonekwe rinosimudzira' rekuvandudza maindasitiri
"Chifananidzo" chesilicon carbide inoputika nekuita kwakapinda munzvimbo dzakasiyana-siyana, kubva kumagwara anodzivirira kukurwa kwevhu mumaovheni esimbi kusvika kumapaipi anodzivirira ngura mumidziyo yemakemikari. Kuvapo kwayo hakungogumiri pakuwedzera hupenyu hwemidziyo chete, asiwo kunobatsira mabhizinesi kuchengetedza simba nekuderedza kushandiswa - semuenzaniso, mumunda wemaovheni emaindasitiri, kushandiswa kwefenicha yemaovheni esilicon carbide kunogona kuderedza zvakanyanya kurasikirwa nekupisa.
Mhedziso
'Kugona' kwesimbi dzecarbide kunopfuura izvi. Semunhu anotungamira mukugadzira tekinoroji ye "reaction sintering", tinoramba tichigadzirisa maitiro acho kuti tiwedzere kukosha kwesimbi iyi munzvimbo dzakaoma. Kana uchitsvaga mishonga yeindasitiri inodzivirira kupisa, inodzivirira kukuvadzwa, uye inogara kwenguva refu, ungangoda kutarisisa mikana yakawanda yesimbi dzesilicon carbide!
Shandong Zhongpeng yave ichinyanya kutarisa pakutsvaga nekugadzira reaction sintered silicon carbide kwemakore anopfuura gumi, ichipa mhinduro dzeceramic dzakagadzirirwa vatengi vepasi rose.
