Popanga mafakitale, mapaipi amakhala ngati "mitsempha yamagazi" yomwe imanyamula zinthu zowononga kwambiri monga ore, ufa wamalasha, ndi matope. Pakapita nthawi, makoma amkati a mapaipi wamba amavalidwa mosavuta komanso obowoka, zomwe zimafunikira kusinthidwa pafupipafupi komanso zomwe zingakhudze kupanga chifukwa cha kutayikira. Panthawi imeneyi, zinthu amatchedwa"paipi ya silicon carbide kuvala yosagwira"zidafika pothandiza. Zinali ngati kuyika “chovala chotchinga zipolopolo” papaipi, kukhala “mbuye” polimbana ndi kung’ambika kwa zinthu zakuthupi.
Wina angafunse, kodi silicon carbide ndi chiyani? M'malo mwake, ndi chinthu chopangidwa mwaluso chokhala ndi cholimba kwambiri. Mwachitsanzo, khoma lamkati la payipi lokhazikika lili ngati pansi pa simenti yovuta, ndipo zinthu zikamadutsa m’kati mwake, nthawi zonse “zimakanda” pansi; Khoma lamkati la mapaipi a silicon carbide lili ngati miyala yolimba yopukutidwa, yokhala ndi mphamvu zochepa komanso kuvala kopepuka pamene zinthu zikuyenda. Khalidweli limapangitsa kuti likhale lamphamvu kwambiri pakukana kuvala kuposa mipope wamba yachitsulo ndi mapaipi a ceramic, ndipo ikagwiritsidwa ntchito popereka zida zapamwamba, moyo wake wautumiki ukhoza kukulitsidwa kangapo.
Komabe, silicon carbide yokha ndi yolimba ndipo imatha kusweka mosavuta ikapangidwa mwachindunji kukhala mapaipi. Mapaipi ambiri amakono a silicon carbide osamva kuvala amaphatikiza zida za silicon carbide ndi mapaipi achitsulo - mwina pomata wosanjikiza matailosi a silicon carbide ceramic pakhoma lamkati la payipi yachitsulo, kapena kugwiritsa ntchito njira zapadera kusakaniza ufa wa silicon carbide ndi zomatira, zokutira khoma lamkati la payipi kuti apange wosanjikiza wolimba wosamva. Mwanjira iyi, payipi imakhala ndi kulimba kwachitsulo, komwe sikumapunduka kapena kusweka, komanso kukana kwa silicon carbide, kulinganiza kuchitapo kanthu komanso kulimba.
Kuphatikiza pa kukana kuvala, mapaipi osamva kuvala a silicon carbide alinso ndi maubwino okwera komanso otsika kutentha komanso kukana dzimbiri. Zida zina zamafakitale sizongowonongeka kwambiri, komanso zimatha kukhala ndi acidic kapena zamchere. Mapaipi wamba amawonongeka mosavuta ndi kukhudzana kwa nthawi yayitali, pomwe silicon carbide imakhala yolimba kukana asidi ndi alkali; Ngakhale kutentha kwa zinthu zonyamulidwa kusinthasintha, ntchito zake sizidzakhudzidwa kwambiri, ndipo zochitika zake zogwiritsira ntchito zimakhala zazikulu kwambiri, kuchokera ku migodi ndi mphamvu kupita ku mafakitale a mankhwala ndi zitsulo, kumene kupezeka kwake kungawonekere.
Kwa mabizinesi, kugwiritsa ntchito mapaipi osamva a silicon carbide sikungolowetsa chinthu chimodzi, komanso kumachepetsa kuchuluka kwa chitoliro m'malo, kumachepetsa mtengo wokonza nthawi yocheperako, komanso kumachepetsa zoopsa zomwe zimayambitsidwa ndi kutayikira kwazinthu. Ngakhale kuti ndalama zake zoyamba ndizokwera kuposa za mapaipi wamba, m'kupita kwanthawi, zimakhala zotsika mtengo.
Masiku ano, ndi kuchuluka kwa kufunikira kwa kulimba kwa zida ndi chitetezo pakupanga mafakitale, kugwiritsa ntchito mapaipi osamva kuvala a silicon carbide kukuchulukirachulukira. "Kukweza mapaipi" owoneka ngati osafunikira kumabisadi nzeru zaukadaulo wazinthu zamafakitale, kupangitsa kuti ntchito yopangira ikhale yokhazikika komanso yogwira mtima - iyi ndi payipi ya silicon carbide yosamva kuvala, "katswiri wosamva kuvala" amayang'anira mwakachetechete "mitsempha yamagazi" yamakampani.
