Bonded metallic hmoov txheej muab cov nyhuv ua haujlwm tas li

Bonding Nyob rau hauv 1980, ib tug txheej txheem ntawm bonded metallic hmoov txheej tau qhia rau ntxiv cov nyhuv pigments rau hmoov txheej. Cov txheej txheem yuav tsum ua raws li cov nyhuv pigments rau cov hmoov txheej txheej kom tiv thaiv kev sib cais thaum siv thiab rov ua dua tshiab.

Tom qab kev tshawb fawb thaum xyoo 1980s thiab thaum ntxov 90s, cov txheej txheem txuas ntxiv ntau theem rau kev sib txuas tau qhia. Lub ntsiab kom zoo dua nrog cov txheej txheem Bonding yog qib ntawm kev tswj hwm tag nrho cov haujlwm. Batch loj dhau los ua qhov teeb meem tsawg dua thiab muaj cov yam ntxwv zoo ntawm daim ntawv thov. Cov txheej txheem no tau ua tiav hauv Tebchaws Meskas thaum xyoo 1996. Txhawm rau tsim cov txheej txheem, nws yog thawj zaug uas yuav tsum muaj txoj hauv kev los txiav txim siab tias cov khoom lag luam raug sib raug zoo. Saibral Cov txheej txheem tau tsim los kuaj xyuas kev sib raug zoo, suav nrog kev yees duab microscopy, ntau yam kev them nyiaj, thiab kev ntsuas cua daj cua dub.

Kev ntsuam xyuas tau ua kom muaj nuj nqis thiab sib piv cov xim Cov nyhuv sib txawv tshwm sim los ntawm kev sib xyaw qhuav thiab Bonding. Txawm hais tias nws yog ib qho nyuaj kom tau txais ib qho txiaj ntsig rau kev ntsuas xim, uas yog proportional rau cov ntsiab lus pigment, nws tau txiav txim siab siv lub teeb pom kev ntawm tsib lub kaum ntse ntse. Lub lightness nkhaus ntawm lub hauv paus khoom yog txhais raws li 0% thiab cov nkauj xwb hlau hmoov li 100%. Cov khoom tau dhau los ntawm cov cua daj cua dub thiab L- qhov tseem ceeb rau txhua qhov kev khiav ntawm tsib lub kaum ntse ntse. Tom qab peb khiav cov hmoov sib tov qhuav qhia tau hais tias cov nyhuv poob ntawm 50%.

Tam sim no koj tab tom nug "vim li cas ib tug neeg puas yuav siv tsis tau daim ntawv cog lus?" thiab "Kuv tuaj yeem qhia tau li cas yog tias kuv cov hmoov sib raug zoo los tsis yog". Tsuas yog vim li cas leej twg siv tsis yog daim ntawv cog lus yog vim lawv pheej yig dua. Hmoov manufacturers generally tsis yog tsim tshiab, uas tsis yog-bonded formulations, tab sis lawv muaj sevral Tshuag xim uas lawv tuaj yeem ua tau li ntawd vim tias cov neeg siv khoom txuas ntxiv mus yuav lawv (qee cov neeg siv khoom tsis paub qhov txawv ... piv txwv li, lawv yuav muaj feem me me kom pom qhov tsis sib xws). Txawm li cas los xij, ob peb lub tuam txhab tseem tuaj yeem tsim cov hmoov tsis muaj kev sib koom tes vim qhov tseeb tias tsis yog tag nrho cov txiaj ntsig xav tau los ntawm lawv cov neeg siv khoom tuaj yeem ua tau los ntawm kev sib koom ua ke.

Tag nrho cov hmoov chemistry tau ua tiav kev sib raug zoo nrog rau hybrids, TGIC, Primid, thiab GMA acrylics
