Mukugadzirwa kwemaindasitiri, mapaipi akafanana ne "tsinga dzeropa" dzinotakura zvinhu zvinorema zvakanyanya zvakaita sematombo, hupfu hwemarasha, uye dhaka. Nekufamba kwenguva, madziro emukati emapaipi akajairwa anosvuuka nyore nyore uye anoboorwa, zvichida kutsiviwa nguva nenguva uye zvinogona kukanganisa kugadzirwa nekuda kwekubuda kwemvura. Panguva ino, chinhu chinonzi"pombi inodzivirira silicon carbide"Zvakanga zvakaita sekuisa "jasi rinodzivirira mabara" papombi, kuva "nyanzvi" mukugadzirisa kusakara kwezvinhu.
Mumwe munhu angabvunza kuti, chii chinonzi silicon carbide? Kutaura zvazviri, chinhu chisina kugadzirwa chakagadzirwa nemaoko chine chimiro chakasimba. Semuenzaniso, madziro emukati mepombi yenguva dzose akaita sepasi resimende rakashata, uye sezvo zvinhu zvichiyerera nepakati paro, zvinogara "zvichikwenya" ivhu; Rusvingo rwemukati rwemapombi esilicon carbide rwakafanana nemasirabhu ematombo akaomarara akakwenenzverwa, ane simba shoma uye kusakara kwakareruka kana zvinhu zvichipfuura nepakati. Hunhu uhwu hunoita kuti ive yakasimba zvikuru mukudzivirira kusakara kupfuura mapombi esimbi akajairwa nemapombi eceramic, uye kana ikashandiswa mukutakura zvinhu zvinopera zvakanyanya, hupenyu hwayo hwebasa hunogona kuwedzerwa kakawanda.
Zvisinei, silicon carbide pachayo haina kusimba uye inogona kupwanyika zviri nyore kana yagadzirwa zvakananga kuita mapaipi. Mapaipi mazhinji esilicon carbide asingatsvedzeri anosanganisa zvinhu zvesilicon carbide nemapaipi esimbi - kungave nekunamira jira re silicon carbide ceramic tiles pamadziro emukati mepaipi yesimbi, kana nekushandisa maitiro akakosha ekusanganisa silicon carbide powder ne namira, kuputira madziro emukati mepaipi kuti igadzire jira rakasimba risingatsvedzeri. Nenzira iyi, paipi ine zvese kusimba kwesimbi, iyo isingakanganiswe kana kuputsika nyore, uye kuramba kusakara kwesilicon carbide, zvichienzanisa kushanda uye kugara kwenguva refu.
Pamusoro pekusapfeka, mapaipi asingatsvedzeri silicon carbide anewo zvakanakira zvekusapfeka zvakanyanya uye kusapfeka zvakanaka. Zvimwe zvinhu zvemaindasitiri hazvingogumburi zvakanyanya chete, asi zvinogonawo kuva neacidic kana alkaline. Mapaipi akajairwa anogona kusviba nyore nyore nekubata kwenguva refu, nepo silicon carbide ichiramba zvakanyanya acid nealkali; Kunyangwe tembiricha yezvinhu zvinotakurwa ikachinja-chinja, mashandiro ayo haazokanganisike zvakanyanya, uye mamiriro ekushandiswa kwayo akafara zvikuru, kubva kumigodhi nemagetsi kusvika kumaindasitiri emakemikari nesimbi, uko kuvapo kwayo kunogona kuonekwa.
Kumabhizinesi, kushandisa mapaipi asingatsvedzeri silicon carbide hakungotsivi chinhu chimwe chete, asi kunoderedzawo kuwanda kwekutsiviwa kwemapaipi, kunoderedza mari yekugadzirisa nguva yekushanda, uye kunoderedza njodzi dzekuchengetedza dzinokonzerwa nekubuda kwemvura. Kunyangwe mari yayo yekutanga yakakwira kupfuura yemapaipi akajairwa, nekufamba kwenguva, inodhura zvishoma.
Mazuva ano, nekuda kwekuwedzera kwekugara kwenguva refu kwemidziyo uye kuchengetedzeka mukugadzirwa kwemaindasitiri, kushandiswa kwemapaipi asingatsvedzeri silicon carbide kuri kuramba kuchiwanda. "Kuvandudzwa kwemapaipi" uku kunoratidzika kunge kusingakoshi kunoviga hunyanzvi hwekugadzira zvinhu zvemaindasitiri, zvichiita kuti maitiro ekugadzira ave akasimba uye anoshanda - iyi ndiyo paipi isingatsvedzeri silicon carbide, "nyanzvi isingatsvedzeri" inochengetedza chinyararire "tsinga dzeropa" dzemaindasitiri.
