Kupisa idanho rakakosha asi rakakosha mune zvakawanda zvinhu zvekugadzirwa kwemaindasitiri. Kubva pasimbi kupisa kupisa kusvika kuceramic sintering, uye kunyangwe kugadziridzwa kwezvimwe zvinhu zvakakosha, yakagadzikana, inoshanda, uye inochinjika yekudziya michina inodiwa. Mune izvi zviitiko zvine zvakaomesesa zvinodiwa zvekushisa uye kusimba,silicon carbide mwaranzimachubhu ari kuita sarudzo yeakawanda uye akawanda mabhizinesi nekuda kwemabhenefiti awo akasiyana.
Vamwe vanhu vangave vachida kuziva, chii chinonzi silicon carbide radiation chubhu? Zvichitaurwa zviri nyore, itubular inodziya inogadzirwa zvakanyanya nesilicon carbide ceramics, inowanzo shandiswa pamwe chete newaya dzekudziya, matanda ekudziya uye mamwe macores emukati, uye inotamba basa re "heat exchanger" mumaindasitiri emoto nemimwe michina. Zvisinei, iyo yakasiyana-siyana iri pakuti haigadziri zvakananga kupisa kwepamusoro, asi panzvimbo iyo inoshandura kupisa kune imwe nzvimbo yekushanda iyo inoda kupiswa mumhando yemwaranzi kuburikidza nemukati wekupisa zvinhu zvakaputirwa pairi, uyewo kudzivirira zvikamu zvemukati kubva mumhepo yakaoma mukati memoto.
Kana zvasvika kune zvakanakira silicon carbide radiation machubhu, "yepamusoro tembiricha kuramba" zvirokwazvo ndiyo yakakosha label. Zvekare simbi yekudziya machubhu anogona kusangana nedeformation uye oxidation pakudziya kwemazana akati wandei madhigirii Celsius, nepo silicon carbide ceramics pachayo ine yakanakisa-yepamusoro-tembiricha kuramba. Kunyangwe mumakirini ekupisa kwepamusoro pamusoro pe1300 ℃, anogona kuchengetedza kugadzikana kwechimiro uye haakuvare nyore. Hunhu uhu hunoibvumira kujairana neakawanda epamusoro-tembiricha ekugadzirisa mamiriro, senge tembiricha yekupisa yemamwe akakosha ceramics anowanzo kudarika 1200 ℃, uye silicon carbide radiation machubhu anogona kushanda akavimbika munzvimbo dzakadai kwenguva yakareba.
Pamusoro pekupikiswa kwekushisa kwakanyanya, "corrosion resistance" iriwo chiratidzo chikuru chayo. Mune akawanda maindasitiri ekudziya maitiro, panogona kunge paine acidic, alkaline magasi kana zvimwe zvinhu zvinoparadza muchoto, izvo zvinogona kukanganisa zviri nyore zvinhu zvekudziya uye kupfupisa hupenyu hwebasa remidziyo. Iko kugadzikana kwemakemikari esilicon carbide zvinhu kwakasimba, uye hazvisi nyore kuita nezvinhu izvi zvinoparadza, izvo zvinoreva kuti inogona kuchengetedza kusimba mumhepo yakaoma yemoto, kuderedza kuwanda kwekutsiviwa kwemidziyo, uye nekufamba kwenguva, zvakare kuderedza kugadzirwa nekugadzirisa mutengo wemabhizinesi.
Mukuwedzera, iyo "thermal performance" yesilicon carbide radiation machubhu inofanirwawo kutaurwa. Kupisa kwayo kwekushisa kwakanaka, kunogona kukurumidza kutamisa kupisa kunokonzerwa nemukati wekupisa zvinhu uye kupisa workpiece nemwaranzi. Iyi nzira yekudziya haingopisa nekukurumidza, asiwo inoita kuti kugoverwa kwekushisa mukati memoto kuve yunifomu, kudzivirira kupisa kwenzvimbo kana kusakwana tembiricha. Izvi zvakakosha zvakanyanya pakuona kuenderana kwechigadzirwa chekugadzirisa mhando. Semuenzaniso, mukupisa kwekupisa kwezvikamu zvesimbi, kufanana kwekushisa kunobata zvakananga kuoma, kuoma, uye zvimwe zvinhu zvezvikamu, uye silicon carbide radiation tubes inogona kupa tsigiro yakagadzikana munyaya iyi.
Ehe, kushandiswa kwesilicon carbide radiation machubhu hakusi pasina miganhu. Semuyenzaniso, mutengo wavo wakakwira zvakanyanya kupfuura weyakajairika simbi yekudziya machubhu, uye nekuda kwehunhu hweceramic zvinhu, ivo vanofanirwa kudzivirira kudhumhana kwakanyanya panguva yekuisa uye kushandiswa kudzivirira kukuvara. Asi kune maindasitiri ane zvakakwirira zvinodikanwa zvekupisa tembiricha, kukanganisa kwezvakatipoteredza, uye mhando yechigadzirwa, kugadzikana, kushanda zvakanaka, uye hupenyu hurefu hwaunounza kazhinji hunotsiva zvipingamupinyi izvi zvidiki.
Mazuva ano, nekuvandudzwa kwekugadzirwa kwemaindasitiri kune kunyatsojeka uye kwepamusoro-kumagumo, izvo zvinodikanwa zvemidziyo yekudziya zviri kuramba zvichiwedzera. Seyakanakisa maindasitiri kupisa chinhu, silicon carbide radiation machubhu ari kutamba zvishoma nezvishoma basa rakakura muminda yakadai seceramics, metallurgy, uye zvemagetsi. Zvinogona kunge zvisingatarisi ziso semamwe matekinoroji ari kusimukira, asi ndizvo chaizvo hunhu uhwu hwekunyarara "kunamatira pachinzvimbo chayo" munzvimbo dzakanyanyisa izvo zvinoita kuti ive yakakosha "yepamusoro-inodzivirira tembiricha nyanzvi" mukugadzirwa kwemaindasitiri, ichipa vimbiso dzakavimbika kune dzakasiyana siyana dzinodiwa kupisa maitiro.
