Tshuaj zawv plaub hau ntau lawm txheej txheem

Raws li cov khoom siv tu tus kheej txhua hnub, tshuaj zawv plaub hau cov txheej txheem tsim muaj ntau theem, los ntawm kev xaiv cov khoom siv raw mus rau cov khoom ntim tiav, txhua yam yuav tsum tau tswj nruj kom ntseeg tau cov khoom ruaj ntseg, ruaj khov, thiab ua haujlwm zoo. Kab lus no qhia txog cov txheej txheem tsim cov tshuaj zawv plaub hau, npog cov kauj ruam tseem ceeb xws li kev npaj cov khoom siv raw, kev sib xyaw mis, thiab ntim / ntim.

 

Raw Material Preparation thiab Pretreatment

Shampoo ntau lawm cia siab ua ntej thiab foremost ntawm leej proportioning thiab pretreatment ntawm raw cov ntaub ntawv. Cov ntaub ntawv tseem ceeb muaj xws li surfactants (xws li sodium lauryl ether sulfate), cov neeg ua hauj lwm txias (xws li roj silicone), thickeners (xws li carbomer), preservatives, fragrances, thiab deionized dej. Surfactants yog cov khoom tseem ceeb hauv cov tshuaj zawv plaub hau, lub luag haujlwm rau kev tu tawv taub hau thiab plaub hau; conditioning agents txhim kho cov plaub hau smoothness thiab ci.

Ua ntej kev tsim khoom, tag nrho cov khoom siv raw yuav tsum tau kuaj xyuas kom ua tau raws li lub teb chaws tus qauv. Cov ntaub ntawv ua kua (xws li dej deionized) yuav tsum tau lim thiab lim kom tshem tawm cov impurities thiab kab mob; cov ntaub ntawv raw khoom (xws li thickeners) yuav tsum tau ua ntej -dispersed los yog yaj los txhim kho kev sib xyaw ua ke tom ntej.

 

Formulation Mixing thiab Emulsification

Cov kauj ruam tseem ceeb ntawm cov tshuaj zawv plaub hau yog kev sib xyaw ua ke, uas suav nrog kev sib xyaw ua ke ntawm ntau yam khoom siv raw raws li qhov ntsuas tau ua ntej. Cov txheej txheem no feem ntau suav nrog cov kauj ruam hauv qab no:

1. Kev sib xyaw ua ke: Ntxiv qee cov dej- cov khoom siv soluble (xws li glycerin thiab cov tshuaj ua kom txias) rau lub reactor loj thiab do ntawm qis ceev kom txog thaum yaj tag.

2. Surfactant Ntxiv: Maj mam ntxiv cov surfactants thaum tswj qhov kub thiab txias (feem ntau yog 40-60 degree) kom paub meej txaus dispersion thiab tiv thaiv clumping.

3. Emulsification thiab Homogenization: Yog tias cov mis muaj cov roj (xws li cov roj silicone), emulsification siv lub siab -shear homogenizer yog tsim nyog los xyuas kom meej cov roj sib xws thiab ruaj khov- dej. Cov kauj ruam no ncaj qha cuam tshuam rau kev ntxhib los mos thiab ruaj khov ntawm cov tshuaj zawv plaub hau.

4. Thickening thiab pH Kho: Ntxiv cov thickeners (xws li sodium chloride los yog carbomer) los kho cov khoom viscosity, thiab siv pH adjusters (xws li citric acid) los tswj pH tus nqi ntawm 5.5 thiab 7.0 kom haum rau cov tawv taub hau ib puag ncig.

Nruam stirring yog yuav tsum tau nyob rau hauv lub mixing txheej txheem los xyuas kom meej ib tug uniform tis ntawm tag nrho cov Cheebtsam, thaum tsis txhob ntau tshaj nplawm uas yuav ua rau cov npuas ntau dhau thiab cuam tshuam rau cov khoom zoo li.

 

Stability Test thiab Lim

Tom qab sib tov, cov tshuaj zawv plaub hau tau luv luv - lub sij hawm ntsuas kev ruaj ntseg, suav nrog kev kub siab (45 degree), qhov kub thiab txias (-5 degree), thiab kev soj ntsuam hauv chav tsev kub, kom ntseeg tau tias nws tsis sib cais, nag lossis daus hauv qhov chaw sib txawv.

Tom qab ntawd, cov khoom tau dhau los ntawm kev lim dej (piv txwv li, 0.2-0.5 micron daim nyias nyias) kom tshem tawm cov khoom ua tau los yog cov khoom tsis huv, ua kom cov zawv plaub hau kom meej meej thiab kev ntxhib los mos.

 

Filling thiab Ntim

Cov tshuaj zawv plaub hau uas tau kuaj thiab tsim nyog tau mus rau theem puv. Kev tsim cov tshuaj zawv plaub hau niaj hnub no feem ntau siv cov kab puv puv kom paub meej qhov ntsuas thiab kev nyiam huv. Cov txheej txheem tseem ceeb suav nrog:

1. Kev ntxuav lub raj mis thiab kom tsis muaj menyuam: cov ntim ntim (xws li lub raj mis yas) yuav tsum tau ua kom tsis muaj kab mob ultraviolet lub teeb lossis ozone kom tsis txhob muaj cov kab mob sib kis.

2. Quantitative Filling: Cov tshuaj zawv plaub hau tau ntim rau hauv lub raj mis raws li lub ntim ntim (xws li 200ml, 400ml) siv lub tshuab filling, thaum tswj qhov sib xws ntawm cov kua theem.

3. Capping thiab Labeling: Tom qab sau, lub hau lub raj mis nruj nruj thiab ib daim ntawv lo ntawm cov khoom yog affixed, qhia cov khoom xyaw, hnub tsim khoom, thiab cov lus qhia rau kev siv . 4. Kev ntim khoom sab nraud: Nyob ntawm kev xav tau ntawm kev lag luam, tshuaj zawv plaub hau tuaj yeem ntim ntxiv rau hauv cov thawv ntawv lossis lub thawv khoom plig rau kev thauj mus los yooj yim thiab muag khoom.

 

Kev soj ntsuam zoo thiab xa khoom xa tuaj
Thaum kawg, cov tshuaj zawv plaub hau tiav dhau los ua qhov kev ntsuas zoo, suav nrog cov ntsuas microbiological (xws li tag nrho cov kab mob suav thiab pwm), physicochemical zog (viscosity thiab pH tus nqi), thiab kev ntsuas kev hnov ​​​​qab (ntsuab thiab ua npuas ncauj nplua nuj). Tsuas yog cov khoom ua tau raws li cov qauv tuaj yeem tawm hauv lub Hoobkas thiab nkag mus rau hauv kev ua lag luam.

 

Cov txheej txheem tshuaj zawv plaub hau sib xyaw ua ke tshuaj lom neeg, engineering, thiab kev tswj hwm thev naus laus zis, nrog rau txhua kauj ruam tseem ceeb rau kev ua haujlwm ntawm cov khoom kawg. Kev tswj xyuas kev tsim khoom thiab kev tswj xyuas nruj yog qhov tseem ceeb kom ntseeg tau tias cov neeg siv khoom tau txais kev nyab xeeb thiab ua tau zoo ntawm kev zawv plaub hau. Nyob rau hauv lub neej yav tom ntej, nrog rau kev loj hlob ntawm ntsuab chemistry thiab sustainable ntau lawm lub tswv yim, zawv plaub hau txheej txheem yuav tsum optimized ntxiv kom txo tau ib puag ncig tej yam kev mob thiab txhim kho cov neeg siv kev.
