Ua ntej, iav frosting hmoov yog dab tsi?
iav frosting hmoov, feem ntau yog fluoride (xws li ammonium fluoride, poov tshuaj fluoride, calcium fluoride) ua lub ntsiab tivthaiv, thiab ces ntxiv ammonium sulfate, barium sulfate, poov tshuaj sulfate thiab lwm yam additives los npaj frosted hmoov.
Thaum siv, sulfuric acid los yog hydrochloric acid yog ntxiv los npaj cov kua frosting, cov khoom iav tau muab tso rau hauv cov kua frosting no, thiab cov hydrofluoric acid tsim los ntawm cov tshuaj tiv thaiv ntawm cov hmoov frosting thiab acid erodes iav khoom kom ua tiav cov nyhuv frosting.
Qhov thib ob, qhov txawv ntawm frosted hmoov thiab etching cream yog dab tsi?
Iav frosting yog ib txoj hauv kev kho cov iav nto nrog kev daws teeb meem lossis lwm yam khoom siv raw khoom tsim nrog iav frosting hmoov. Frosting yog ib qho ntawm cov txheej txheem ntawm kev ua cov iav sib sib zog nqus, uas tuaj yeem ua rau tus nqi ntxiv ntawm iav thiab yog li ua kom tus nqi ntawm cov khoom iav. Tam sim no, ntau lub iav kos duab ntawm kev ua lag luam tau ua tiav los ntawm iav frosting thiab tom qab ntawd xim.
Iav etching cream thiab iav frosting hmoov yog cov ntaub ntawv zoo rau cov khoom siv iav frosting, tab sis lawv tsim nyog rau kev ua haujlwm sib txawv. Nyob rau tib lub sij hawm, lawv lub luag hauj lwm nyob rau hauv lub iav kev lag luam yog complementary thiab complementary.
Frosting cream yog feem ntau haum rau ib nrab frosting ntawm iav khoom, uas yog yooj yim dua rau kev khiav lag luam; Txawm li cas los xij, frosting paste tsis haum rau thaj tsam loj iav etching, lub ntsiab yog vim li cas thaum nws yog siv rau loj-thaj iav etching, nws yog ib qho yooj yim los tsim uneven frosting nto thiab lwm yam tshwm sim. Masking paste feem ntau yog siv hauv kev tshuaj ntsuam luam ntawv.
Piv nrog frosting muab tshuaj txhuam, cov txheej txheem kev ua haujlwm yog me ntsis nyuab dua nrog cov hmoov frosting, uas yog, nws yog ib qho tsim nyog los npaj cov hmoov frosting rau hauv kev daws. Txawm li cas los xij, frosting hmoov yog haum rau yuav luag tag nrho cov iav khoom. Nws tuaj yeem tsis tsuas yog cov khoom khov iav xws li iav, iav fwj, iav teeb pom kev zoo, thiab lwm yam uas tuaj yeem tsau rau hauv cov tshuaj; Nws tseem tuaj yeem ua sanded rau cov khoom siv iav xws li iav tiaj tus thiab zawv zawg qhov rooj iav uas yuav tsum tsis txhob ntub hauv cov kua frosting, tab sis xav tau frosting. Muaj ob txoj hauv kev rau cov khoom khov iav nrog cov hmoov frosting: soaking thiab xuab zeb.
