Invisible 'Steel Armor': Kodi Mphamvu ya Silicon Carbide Wear Restant Pipe Lining ndi Chiyani?

M'makona a zokambirana za mafakitale ndi kayendetsedwe ka migodi, pali "udindo" wofunikira koma wosavuta kunyalanyaza - payipi yotumizira. Amayenda ndi mchere, matope, ndi mankhwala tsiku ndi tsiku, ndipo makoma ake amkati nthawi zonse amagwedezeka ndi kukhudzidwa ndi zipangizo. M'kupita kwa nthawi, amatha kuvala ndi kung'amba, kutayikira, zomwe sizimangokhudza kupanga komanso zimafuna kukonza ndi kukonzanso mtengo. Mapaipi osamva kuvala a silicon carbide omwe tikambirana lero ali ngati kuyika "zida zachitsulo zosaoneka" pamapaipi wamba, ndikuthetsa vuto lalikululi mwakachetechete.
Wina angafunse kuti, ndi chiyanisilicon carbide? Ndipotu si zachinsinsi. Kwenikweni, ndi chinthu chopangidwa mwaluso chopangidwa ndi kaboni ndi silicon, cholimba chachiwiri ndi diamondi.
Poyerekeza ndi khoma lamkati la mapaipi wamba, kuuma kwa silicon carbide lining ndikokwera kangapo. Pamene miyala yakuthwa ndi matope othamanga kwambiri akutsuka pakhoma lamkati, silicon carbide imatha kukhala ngati chishango chotchinga kugundana ndikuletsa kukwapula kapena zobowoka mosavuta. Ngakhale pakuyenda kwanthawi yayitali kwa zida zobvala zapamwamba, khoma lake lamkati limatha kukhala lathyathyathya komanso losalala, popanda kukhala lolimba kapena lolimba chifukwa cha kuvala, kukulitsa kwambiri moyo wautumiki wa payipi.

Kuphatikiza pa kukana kuvala, ilinso ndi luso lobisika - 'limatha kupirira zomangamanga'. Popanga mafakitale, zinthu zomwe zimaperekedwa nthawi zambiri sizingokhala "nthaka", komanso zimatha kunyamula kutentha kwambiri komanso dzimbiri la acid-base. Mwachitsanzo, pankhani ya uinjiniya wa mankhwala, zinthu zina zimakhala ndi dzimbiri lamphamvu, ndipo mizere ya mapaipi wamba imakhala ndi dzimbiri ndi kusenda mosavuta; M'makampani opanga zitsulo, zinthu zotentha kwambiri zimatha kuyambitsa mapindikidwe ndi kulephera kwa akalowa. Mzere wa silicon carbide umatha kupirira kutentha kwa madigiri mazana angapo Celsius ndikukana kukokoloka kwa zinthu zambiri za acidic ndi zamchere, ndikusunga magwiridwe antchito "malo ovuta" aliwonse.
Kwa mabizinesi, zopindulitsa zomwe zimabweretsedwa ndi kansalu kakang'ono kameneka ndizowoneka bwino: palibe chifukwa chotseka pafupipafupi ndikulowetsa mapaipi, kuchepetsa kutayika komwe kumachitika chifukwa cha kusokonezeka kwa kupanga; Palibe chifukwa chochitira ndalama mobwerezabwereza ndalama zosamalira, zimatha kusunga ndalama zambiri pakapita nthawi; Chofunika koposa, imatha kuonetsetsa kuti zinthu zikuyenda bwino komanso kupewa ngozi zachitetezo komanso zovuta zachilengedwe zomwe zimadza chifukwa cha kutayikira kwa mapaipi.
Kuchokera pazitsulo zosawoneka bwino za mapaipi kupita ku "chida chosamva kuvala" chomwe chimateteza kupanga mafakitale, mtengo wa silicon carbide wosamva kuvala wa mapaipi wagona pakutha kwake "kuthetsa mavuto akulu ang'onoang'ono". Kwa mabizinesi omwe amatsata kupanga koyenera komanso kosasunthika, kusankha sikungowonjezera zida, komanso kulingalira kwanthawi yayitali pakupanga bwino komanso kuwongolera mtengo.
