Ukucisha ukwelashwa kokushisa kwendawo ethambile yepayipi lensimbi engenamthungo

1. Liyini iphuzu elithambile elicishayo

Iphuzu elithambile elibizwa ngokuthi i-quenching liyindawo ethambile engapheli ezingxenyeni.Ngakho-ke, ibizwa nangokuthi i-softspot (i-softspot) .Iphuzu elithambile lokucisha amanzi libi kakhulu kunalelo lokucisha amafutha, ngoba ubuso bunefilimu ye-steam. ukunciphisa isivinini sokupholisa.Lesi senzakalo ngokuvamile saziwa ngokuthi yi-Leiden frosting phenomenon.Nakuba ukucisha uwoyela kuwubulukhuni obanele, okungukuthi, ukucisha okwanele, kodwa akulula ukubangela iphuzu elithambile lokucisha.Nokho, ukwehlisa lapho i-decarbonization noma isikhumba se-oxidation. kufana nokucisha iphuzu elithambile.

Kuthiwa ngesikhathi semvula iplamu ijwayele ukucisha iphuzu elithambile, uma umswakama wendawo yokucisha ungaphezu kuka-55%, ujwayele ukucisha iphuzu elithambile.

Ingaphezulu lezingxenye zokucisha imvamisa ephezulu lijwayele ukuba nesibazi se-barber, noma unqenqema lommese wase-Japan, imibala egqamile ivala iphuzu elithambile.I-microtissue yephoyinti elithambile elicishayo i-martensite kanye ne-pearlophyte ezacile kakhulu (i-nodular flexter) enombala ogqamile.

2. Ungalithola kanjani iphuzu elithambile lokucisha

Ngokuvamile kunezindlela ezintathu zokuthola amaphuzu athambile acishiwe.Indlela yokuqala iwukubona umbala okhanyayo ocwebezelayo endaweni yokugaya: indlela yesibili ukuthi indlela yesithathu iwukusebenzisa ukugqwala kwe-asidi ukuze uthole iphuzu elithambile elicimayo;okungukuthi, ukucwilisa izingxenye ku-50% isixazululo samanzi e-hydrochloric acid (amanzi amanzi) ukuze kugqwale, uma ingxenye engaphezulu ibonakala ibala elimnyama, indawo emnyama iyindawo ethambile yokucisha.Nokho, kufanele kuqashelwe ukuthi ukushisa okuphansi kokushisa (180) ~200C) izingxenye zigqwalile endaweni eqinile, futhi umbala endaweni engaqinile.Ukujula kongqimba olucishiwe kungalinganiswa kusetshenziswa le ndlela.

3. Ungakuvimbela kanjani ukucisha kusuka endaweni ethambile

Ukuze uvimbele ukucisha amaphuzu athambile, ungafaki i-oxidize noma ukhiphe i-carbon izingxenye lapho ushisa kuqala.Okwesibili, ukuze uvimbele ubuso bezingxenye ezixhunywe ngefilimu ye-vapor yamanzi, kungcono ukugqugquzela ngokugcwele uketshezi lokucisha bese usebenzisa isifutho samanzi epholile.Ngaphezu kwalokho, uma ukucisha ngamanzi anosawoti angu-10% kungavimbela ngokuphelele ukucinywa kwamaphuzu athambile.Ngaphezu kwalokho, ukusebenzisa ungqimba omncane we-polish powder ebusweni bezingxenye zokucisha nakho kuyindlela enhle yokuvimbela ukucinywa kwezinto ezithambile. amaphuzu.Impushana yokupholisha iphole ngokushesha kunezingxenye zensimbi ezingagcotshiwe futhi ayicimi indawo ethambile, ngakho ukusebenzisa impushana yokupholisha emsebenzini wokucisha ummese waseJapane kuyindlela eyimfihlo.Kodwa kufanele ithathwe.Uma impushana yokupholisha ishubile kakhulu, ukupholisa kuhamba kancane, akunzima.

I-powder ecwebezelayo incane futhi isetshenziswe ebusweni bezingxenye zokucisha, futhi lapho kucima, indawo engaphezulu ayizungezwe ifilimu ye-steam, eba ama-bubbles amancane futhi iphakama ngenkuthalo, ngakho ipholisa ngokushesha.

Njenge-ejenti yokugqoka, ngaphezu kwempushana yokupholisha.Nomlotha nekaolini namanzi;i-mica ngaphandle kobumba oluthambile namanzi: i-pumice enobumba oluthambile namanzi, lezi kuthiwa ziyizindlela zokupheka ezinhle.

Muva nje, isisombululo sokucima amanzi esincibilika emanzini (isixazululo se-polymer quenching) sisetshenziswa kakhulu esikhundleni samafutha okucisha, ane-solubility ephambene futhi engenza ifilimu ebusweni lapho ishiswa izingxenye eziphathwayo.Lapho izinga lokushisa lehlela cishe ku-90℃ (ezinye izixazululo zingu-74℃), imaski yangaphezulu iyancibilika.Ngakho-ke, ukupholisa ebangeni lokushisa eliphezulu kungenziwa ngokulinganayo ukuze kuvinjelwe ukucisha kwamaphuzu athambile.Umphumela muhle njengokuthi egcoba impushana yokupholisha ngayo}

Ukwengeza, uma ukupholisa kwe-ultrasonic ” amaviki angu-25000 / s), ifilimu yomhwamuko ingasuswa ngokuphumelelayo, ngakho-ke ukucisha amaphuzu athambile nakho kungavinjelwa.Ukupholisa kwe-Ultrasonic kuyindlela entsha yokupholisa.
