Hauv kev lag luam tshuaj pleev ib ce, pigments ua lub luag haujlwm tseem ceeb hauv kev txiav txim siab qhov tsos thiab zoo ntawm cov khoom xws li eyeshadows, blushes, lipsticks, thiab foundations. Cov neeg tsim khoom cia siab rau cov txheej txheem meej kom ntseeg tau tias cov xim no tswj lawv cov xim zoo thiab zoo thoob plaws hauv kev tsim khoom. Ntawm cov txheej txheem ntau lawm, kev siv cov tshuab ua kom zoo nkauj hmoov pulverizer yog qhov tseem ceeb hauv kev hloov cov xim nyoos rau hauv cov hmoov zoo. Txawm li cas los xij, ib qho kev txhawj xeeb ntawm cov tuam txhab tshuaj pleev ib ce yog seb cov txheej txheem sib tsoo thiab pulverization tuaj yeem hloov xim lossis xim zoo.
1. Lub luag haujlwm ntawm Pigments hauv Tshuaj pleev ib ce
Pigments yog cov hauv av zoo uas muab cov xim rau cov tshuaj pleev ib ce. Lawv tuaj yeem yog hluavtaws (xws li titanium dioxide thiab hlau oxides) lossis ntuj (xws li mica thiab ntxhia- raws li pigments). Cov xim xim, qhov loj me, thiab lub teeb pom kev zoo yog qhov tseem ceeb hauv kev ua tiav qhov xav tau thiab kev ntxhib los mos hauv cov khoom kawg.
Thaum cov tuam txhab tsim cov tshuaj pleev ib ce, lawv feem ntau sib xyaw cov xim nrog lwm cov khoom xyaw, xws li roj, waxes, thiab emulsifiers. Lub tshuab pulverizing plays lub luag haujlwm tseem ceeb hauv qhov no los ntawm kev sib tsoo cov xim rau hauv cov hmoov zoo, ua kom yooj yim sib xyaw nrog lwm cov khoom. Txawm li cas los xij, kev tuav tsis raug thaum lub sijhawm pulverization tuaj yeem cuam tshuam cov xim xim sib xws, ua rau muaj qhov tsis sib xws hauv cov khoom kawg.
2. Lub tshuab Pulverizer ua haujlwm li cas
Lub tshuab tshuaj pleev ib ce hmoov pulverizer siv ntau txoj kev sib tsoo los txo cov ntaub ntawv raw rau hauv cov khoom zoo. Muaj ntau ntau hom tshuab siv nyob rau hauv kev lag luam tshuaj pleev ib ce, xws li dav hlau mills, rauj mills, thiab pob mills. Txhua lub tshuab no siv txoj kev sib txawv ntawm kev sib tsoo, tab sis lawv lub hom phiaj yog los rhuav tshem cov ntaub ntawv rau hauv cov hmoov nrog ib qho me me thiab kev ntxhib los mos.
Cov txheej txheem pulverization feem ntau suav nrog lub zog siv hluav taws xob siv rau cov khoom siv hauv kev cuam tshuam, compression, lossis shear force. Thaum qhov no yog qhov tsim nyog kom tau txais cov hmoov zoo, nws tuaj yeem tsim cov cua sov thaum lub sij hawm sib tsoo. Qhov kub no yog ib qho kev txhawj xeeb tseem ceeb thaum nws los txog rau cov xim zoo vim tias nws tuaj yeem ua rau muaj kev hloov xim thiab degradation ntawm cov xim zoo.
3. Pulverization tuaj yeem cuam tshuam cov xim xim thiab zoo li cas?
Ntau yam thaum lub sij hawm pulverization txheej txheem tuaj yeem cuam tshuam cov xim xim thiab zoo, suav nrog:
3.1 Thaum tshav kub kub
Qhov tseem ceeb tshaj plaws uas cuam tshuam nrog cov xim sib tsoo yog qhov tsim hluav taws xob. Ntau lub tshuab pulverizing, tshwj xeeb tshaj yog rauj zeb thiab pob zeb, tsim kev sib txhuam thiab cua sov thaum ua haujlwm. Yog tias qhov kub thiab txias dhau lawm, nws tuaj yeem ua rau muaj tshuaj lom neeg hauv cov pigments uas ua rau cov xim fading, discoloration, los yog txawm tawg ntawm cov xim nws tus kheej.
3.2 Kev hloov tshuaj
Thaum lub hom phiaj tseem ceeb ntawm pulverization yog txo qhov me me, kev sib tsoo tshuab tuaj yeem ua rau muaj kev hloov tshuaj lom neeg hauv cov xim. Piv txwv li, kev sib tsoo cov xim zoo li titanium dioxide tuaj yeem ua rau muaj kev hloov pauv ntawm qhov chaw uas yuav cuam tshuam li cas cov xim sib cuam tshuam nrog lub teeb. Cov khoom siv kho qhov muag ntawm cov xim, suav nrog nws qhov ci ntsa iab, kev xav, thiab pob tshab, yog qhov tseem ceeb rau qhov kawg ntawm cov khoom, thiab kev hloov pauv ntawm cov khoom no tuaj yeem cuam tshuam cov khoom zoo tag nrho.
Tsis tas li ntawd, qee cov pigments yog noo noo-sensitive. Thaum raug cov dej noo thaum lub sij hawm milling, pigments zoo li zinc oxide tuaj yeem raug hydrolysis, hloov lawv cov qauv tshuaj thiab xim. Yog li, kev tswj cov dej noo thiab tshuab sealing yog qhov tseem ceeb rau kev txiav txim siab thaum lub sij hawm pulverization txheej txheem los tiv thaiv xws li degradation.
3.3 Particle Loj Distribution
Qhov loj me me ntawm cov xim yog qhov tseem ceeb rau kev ua tiav qhov xav tau tiav thiab kev ntxhib los mos hauv cov khoom pleev xim. Yog tias cov xim pigment loj dhau lawm, lawv yuav tsis sib tov zoo nrog lwm cov khoom xyaw, ua rau muaj qhov tsis sib xws ntawm daim tawv nqaij. Ntawm qhov tod tes, yog tias cov khoom me me dhau lawm, lawv tuaj yeem ua rau tsis muaj opacity lossis kev ntxhib los mos, ua rau cov khoom zoo nkauj heev.
Yuav Ua Li Cas Tiv Thaiv Ne gative teebmeem ntawm Pigment Xim thiab Zoo
4.1 Kev tswj qhov kub thiab txias
Txhawm rau tiv thaiv kom tsis txhob muaj cua sov-ntxhiab xim hloov pauv, cov tuam ntxhab tuaj yeem siv cov txheej txheem tswj qhov kub thiab txias hauv cov txheej txheem pulverization. Huab cua- cov tshuab cais tshuab lossis cov tshuab dav hlau feem ntau nyiam rau lawv lub peev xwm los tsim kom muaj cua sov tsawg dua piv rau rauj zeb lossis pob zeb. Cov tshuab no siv cov cua compressed los zom cov xim, uas pab tiv thaiv kom tsis txhob muaj cua sov.
4.2 Tswj dej noo
Kev tswj cov av noo thiab xyuas kom meej tias cov pigments tau qhuav ua ntej thiab thaum lub sij hawm milling yog lwm qhov tseem ceeb hauv kev khaws cov xim zoo. Ntau lub tshuab pulverizer tuaj nrog ua - nyob rau hauv cov thawv kaw kom tiv thaiv kom tsis txhob ya raws ntawm cov xim thaum sib tsoo. Cov neeg tsim khoom kuj tseem tuaj yeem siv cov khoom siv desiccants los yog lub tshuab ziab khaub ncaws kom tshem tawm cov khoom seem ntawm cov xim ua ntej milling.
4.3 Xaiv Txoj Cai Pulverizer
Xaiv lub tshuab pulverizer uas tsim nyog yog qhov tseem ceeb los xyuas kom meej tias cov xim zoo yog khaws cia thoob plaws hauv cov txheej txheem tsim khoom. Piv txwv li, lub dav hlau mills tau zoo heev rau kev sib tsoo cov xim tsis muaj hluav taws xob ntau dhau. Lawv kuj tso cai rau kev tswj xyuas meej txog qhov loj me me, uas pab tswj kev sib xws hauv cov khoom kawg. Rauj mills thiab pob mills, thaum zoo rau kev sib tsoo cov ntaub ntawv nyuaj, tej zaum yuav tsis haum rau rhiab pigments tshwj tsis yog tias lub tshav kub yog tswj.
4.4 Kev Tswj Xyuas Kev Tswj Xyuas Zoo
Kev tswj xyuas kev tswj xyuas tsis tu ncua yog qhov tseem ceeb los xyuas kom meej tias cov pigments tsis cuam tshuam los ntawm kev sib tsoo. Cov neeg tsim khoom yuav tsum ua kom pom cov xim xim xim thiab ua cov kev ntsuam xyuas colorimetric kom paub tseeb tias cov xim ntawm cov xim tseem zoo ib yam tom qab sib tsoo. Lawv yuav tsum tau soj ntsuam cov particle loj tis thiab optical zog ntawm pigments kom lawv ua tau raws li cov qauv tsim nyog rau kev ua tau zoo thiab zoo li.
Hauv kev xaus, thaum lub tshuab tshuaj pleev ib ce hmoov pulverizer yog qhov tseem ceeb rau kev hloov cov xim nyoos rau hauv cov hmoov zoo, nws yog ib qho tseem ceeb rau cov tuam txhab lag luam kom ua tib zoo tswj cov txheej txheem milling kom tsis txhob muaj qhov tsis zoo ntawm cov xim xim lossis zoo. Cov yam ntxwv xws li kev tsim hluav taws xob, kev hloov tshuaj lom neeg, thiab kev faib khoom me me tuaj yeem cuam tshuam cov khoom kawg ntawm cov xim thiab kev ntxhib los mos.
