Mukugadzirwa kwemaindasitiri, mapaipi akafanana ne "midziyo yeropa" yemidziyo, ine mutoro wekutakura zvinhu "zvinopisa zvinopisa" sejecha, matombo uye magasi ekupisa. Nekufamba kwenguva, madziro emukati emapaipi akajairwa anosakara nyore pasi uye anogona kutodonha, zvinoda kugara achigadziriswa uye kutsiva, uye anogona zvakare kunonoka kufambira mberi kwekugadzira. Muchokwadi, kuwedzera chidimbu che "zvipfeko zvekudzivirira" kune pombi kunogona kugadzirisa dambudziko, irosilicon carbide pipeline liningtichataura nezvazvo nhasi.
Vamwe vanhu vangabvunza, chii chaizvo kwakabva silicon carbide ceramics inonzwika chaizvo "hardcore"? Zvichitaurwa zviri nyore, isimbi yakagadzirwa nesimbi yakaoma sesilicon carbide kuburikidza nemaitiro akakosha, uye chinhu chikuru chayo ndeche "kugara": kuomarara kwayo ndekwechipiri kune dhaimondi, uye inokwanisa kumira nekukukurwa kwejecha nematombo uye zvinhu zvinopisa zvishoma nezvishoma, kusiyana neakajairwa marambi esimbi anowanzoita ngura uye kusakara, uye zvakare inoshingirira kune tembiricha yakakwira uye zvinokanganisa.
Iyo yakakosha yekuisa silicon carbide lining mumapaipi ndeyekuwedzera "yakasimba chipingamupinyi" kumadziro emukati. Pakuisa, hapana chikonzero chekuedza kukuru. Kazhinji yenguva, prefabricated silicon carbide ceramic zvimedu zvinosungirirwa kumadziro emukati epombi ine adhesives akakosha kuti iite yakakwana yekudzivirira layer. Iyi layer ye 'barriers' inogona kunge isingaite gobvu, asi basa rayo rinonyanya kushanda:
Chekutanga, iri 'full wear resistance'. Kunyangwe iri kutakura zvimedu zveore zvine mipendero yakapinza kana yakakwirira-kumhanya inoyerera slurry, pamusoro pesilicon carbide lining inonyanya kutsetseka. Kana zvinhu zvichipfuura, kupesana kuduku, izvo zvisingakanganisi mutsara, asiwo zvinoderedza kushorwa panguva yekutakura zvinhu, zvichiita kuti kufambisa kuve nyore. Mapombi akajairika angangoda kuchengetedzwa mushure mehafu yegore yekusakara uye kubvaruka, nepo mapaipi ane silicon carbide lining anogona kuwedzera zvakanyanya hupenyu hwavo hwesevhisi, kuderedza kunetsa uye mutengo wekudzokororwa pombi kutsiva.
Zvadaro pane "corrosion resistance uye high temperature resistance dual line". Muzviitiko zvakawanda zvemaindasitiri, zvinhu zvinofambiswa zvinotakura zvinhu zvinoparadza zvakaita seasidhi nealkali, uye tembiricha haina kuderera. Micheka yakajairika inogona kunge yakakoromoka uye yakatsemuka, kana kuremara nekupisa kwakanyanya kubikwa. Asi silicon carbide ceramics ivo pachavo vane yakagadzikana makemikari ehupfumi uye havatyi kukukurwa kweasidhi uye alkali. Kunyange kana akaiswa kune tembiricha yepamusoro yemazana akati wandei madhigirii celsius, anogona kuchengetedza fomu yakagadzikana, zvichiita kuti akwanise kushandiswa pombi “munzvimbo dzakaoma” dzakadai semakemikari, metallurgical, uye migodhi.
Imwe pfungwa yakakosha ndeye "kunetseka mahara uye kusashanda". Mapaipi akamisikidzwa nesilicon carbide haadi kuvharwa kazhinji kwekugadzirisa, uye zvakare ari nyore kuchengetedza - iyo yepamusoro haina kujaira kuyera kana zvinhu kurembera, uye inongoda kucheneswa zvishoma nguva dzose. Kune mabhizinesi, izvi zvinoreva kudzikisira njodzi yekukanganiswa kwekugadzira uye kuchengetedza yakawanda yekuchengetedza vashandi uye mutengo wezvinhu, izvo zvakaenzana ne "kuiswa-kamwe chete, kwenguva refu kunetseka kusununguka".
Vamwe vanhu vangafunga kuti jira rakasimba rakadaro rinonyanya kudhura? Kutaura zvazviri, kuverenga "akaundi yenguva refu" kwakajeka: kunyange zvazvo mari yekutanga yezvipfeko zvakaderera yakaderera, inoda kuchinjwa mwedzi mitatu kusvika kushanu; Iyo yekutanga kudyara kwesilicon carbide lining yakakwira zvishoma, asi inogona kushandiswa kwemakore akati wandei, uye avhareji mutengo pazuva wakadzikira. Uyezve, inogona kudzivirira kurasikirwa kwekugadzira kunokonzerwa nekukuvadzwa kwepombi, uye mutengo-unoshanda wakanyanya kukwirira.
Mazuva ano, silicon carbide pipeline lining yave zvishoma nezvishoma yave "inofarirwa mhinduro" yekuchengetedzwa kwepombi yeindasitiri, kubva pamisara inotakura mapaipi mumigodhi, kune inoora mapombi muindasitiri yemakemikari, kusvika kune-yepamusoro-tembiricha flue gasi mapaipi muindasitiri yemagetsi, kuvepo kwayo kunogona kuonekwa. Zvichitaurwa zviri nyore, zvakafanana ne "murindi wega wega" wepombi, akanyarara achichengetedza kushanda kwakanaka kwekugadzirwa kwemaindasitiri nekuoma kwayo uye kusimba - ichi ndicho chikonzero nei makambani mazhinji achizvipira kugadzira mapaipi ne "zvipfeko zvakakosha zvekudzivirira".
