Kev npaj ntawm Base Roj -Wax System
Cov roj-xws li roj castor, roj ntxhia, lossis roj zaub- yog ua ke nrog cov quav ciab- xws li beeswax los yog carnauba wax- nyob rau hauv ib lub nkoj cua sov raws li cov qauv tsim tshwj xeeb. Cov sib tov yog rhuab mus rau ib tug tshwj xeeb kub kom txog rau thaum tag nrho melted thiab meej blended, kom ntseeg tau tias cov waxes yog uniformly yaj nyob rau hauv lub roj theem los tsim ib tug ruaj khov puag matrix. Cov kauj ruam tseem ceeb no txiav txim siab daim di ncauj qhov nyuaj, gloss, thiab molding zog.
Pigment Pre-kev kho thiab Kev Npaj Dispersion
Powdered pigments-xws li hlau oxides, titanium dioxide, organic colorants, los yog pearlescent hmoov-ua ntej- kev sib tsoo los yog ntub dej kev kho mob kom yooj yim rau lawv dispersion nyob rau hauv cov roj- siv quav ciab system. Tom qab ntawd, qhov sib tov yog raug rau ntau lub voj voog dispersion siv cov cuab yeej xws li peb - yob mills, siab -shear dispersers, los yog homogenizers. Cov txheej txheem no ntxiv ua kom zoo dua cov xim me me, ua kom cov xim sib xws thiab du, lis -dawb kev ntxhib los mos, thaum tib lub sijhawm txhim kho xim xim thiab cov khoom zoo.
Mixing thiab Moulding Phase
Cov xim sib txawv sib txawv ntawm cov xim slurry yog ntxiv rau cov roj hauv paus -wax system thiab sib tov kom huv si kom txog thaum homogeneous. Tom qab ntawd cov khoom sib tov tau ntim thiab molded nyob rau hauv kev tswj qhov kub thiab txias, ntws mus rau hauv lipstick pwm los yog raj kom txias thiab solidify. Cov khoom tsim pwm tau raug kuaj xyuas kom ruaj khov- suav nrog kev ntsuas kev tiv thaiv tshav kub, xim sib xws, thiab kev ncaj ncees ntawm cov qauv- txhawm rau xyuas kom meej tias cov khoom siv tshuaj pleev ib ce zaum kawg tswj hwm cov yam ntxwv ua haujlwm zoo thoob plaws ntau yam ib puag ncig.
