Dab tsi yog garnet
Garnet yog ib hom lub pov haum, nrog lub ntiajteb txawj nqus ntawm 3.8 ~ 4. 0, Mohs hardness ntawm 7.5 ~ 8. ntug. Garnet yog qib high-qib abrasive.
Kev siv tseem ceeb ntawm garnet
Garnet tau pib siv rau hauv kev lag luam hauv xyoo 1878 ua abrasive rau cov ntawv xuab zeb nrog me me; Los ntawm 1944 txog 1988, garnet tau siv rau polishing thiab sib tsoo cov tsom iav qhov muag, cov hniav nyiaj hniav kub, cov raj duab, thiab lwm yam; Tom qab xyoo 1988, lub tshuab hluav taws xob siab dej dav hlau tau tawm los thiab tau nrov heev. Garnet tsuas yog muaj kev txiav abrasive nkaus xwb, thiab daim ntawv thov ua tiav ntawm garnet hauv sandblasting thiab dej phwj kho tau pom kev loj hlob tawg.
Kev siv garnet 1:
Nto sandblasting pretreatment ua ntej txau / electroplating Yuav kom tiv thaiv cov khoom cuav los ntawm corrosion mus ntev, sandblasting pretreatment yuav tsum tau nqa tawm ntawm qhov chaw ntawm artifacts ua ntej spraying / electroplating mus cuag lub neej kev pab cuam ntawm coatings / coatings, uas yog, kom ntev. kev pab cuam lub neej ntawm artifacts. Cov yam ntxwv ntawm garnet sandblasting ◆ Qhov siab tshaj plaws ntawm cov xuab zeb blasting zoo tuaj yeem ua tiav los ntawm kev siv garnet sandblasting, thiab kev pab cuam lub neej ntawm cov txheej / txheej yog ntau ntxiv. ◆ Kev ua haujlwm siab thiab tus nqi qis ntawm garnet sandblasting ◆ garnet sandblasting abrasive muaj kev nyab xeeb, tsis muaj tshuaj lom thiab tsis muaj mob. Nws tsis muaj teeb meem rau ib puag ncig thiab cov neeg ua haujlwm kev noj qab haus huv thaum sandblasting. Nws yog ib qho kev noj qab haus huv thiab ib puag ncig-phooj ywg sandblasting abrasive. Cov quartz xuab zeb abrasives feem ntau siv tam sim no yuav ua rau mob hnyav thaum sandblasting, thiab tooj liab sandblasting abrasives uas muaj cov hlau hnyav yuav ua rau mob qog noj ntshav. ◆ Yuav luag tsis muaj plua plav tawm thaum lub sij hawm garnet blasting, thiab qhov chaw ua haujlwm zoo. Raws li cov ntsiab lus, garnet yog ib qho tshiab thiab ua tau zoo sandblasting abrasive, uas yog superior rau cov tsoos abrasive nyob rau hauv cov nqe lus ntawm sandblasting zoo, kev noj qab haus huv thiab ib puag ncig tiv thaiv, sandblasting efficiency, siv nqi thiab sandblasting ua hauj lwm ib puag ncig. Nws yog ib qho khoom kho dua tshiab ntawm cov tsoos abrasive.
Garnet daim ntawv thov txoj kev 2:
Kev kub siab dej dav hlau txiav abrasives Kev kub siab dej dav hlau txiav tshuab cuab yeej yog cov cuab yeej siv ntau lub hom phiaj nrog kev ua tau zoo. Nws qhov tseem ceeb tshaj plaws yog kev ua haujlwm ntawm lub zog dav hlau dav hlau tsis muaj cua sov. Tsis muaj cov txheej txheem thermal hauv kev txiav, yog li nws tuaj yeem txiav tag nrho cov hlau thiab cov khoom tsis yog hlau. Tsis tas li ntawd, garnet txiav precision yog siab, thiab txiav nto tsis tas yuav polished. Cov txheej txheem hlau txiav ib txwm muaj xws li nplaim taws, ntshav, laser txiav, thiab lwm yam, uas yaj cov hlau nrog cua sov. Txoj kev txiav no ua rau cov hlau oxidized ntawm qhov kub thiab txias, deformed thiab discolored, thiab muaj kev ua haujlwm tsis zoo; Cov tsoos txiav ntawm cov ntaub ntawv tsis yog xim hlau (xws li iav, ceramic pobzeb, thiab lwm yam) feem ntau yog siv cov hlau pom, uas yog qeeb hauv kev ceev thiab qhov tseeb tsawg. Kev kub siab dej dav hlau txiav tshuab muaj qhov zoo tshaj plaws hauv kev txiav cov hlau thiab cov khoom tsis yog hlau vim nws qhov nrov nrov. Garnet tsuas yog abrasive muaj nyob rau hauv high-pressure dej dav hlau txiav tshuab.
Garnet siv 3:
Garnet, cov khoom siv lim dej rau kev kho cov dej phwj tuaj, muaj cov yam ntxwv ntawm lub ntiajteb txawj nqus tshwj xeeb, kev ua haujlwm tsis zoo, tiv taus acid, alkali thiab tshuaj lom neeg corrosion, nruab nrab porosity, thiab tsis muaj kev puas tsuaj rau ib puag ncig. Cov dej lim dej, kev pab cuam lub neej thiab kev siv tus nqi ntawm garnet yog zoo dua li cov khoom siv lim dej xws li magnetite thiab ilmenite tam sim no, thiab nws tau nrov heev hauv kev lag luam dej phwj tuaj.
