Hauj lwm yam khoom

keeb kwm:   Tuam Tshoj, Sinopec

Tau qhov twg los: Zoo li paraffin wax, microcrystalline wax kuj yog tsim tom qab refining txheej txheem xws li distillation, crystallization thiab deoiling thaum lub sij hawm roj av ua tiav.

purity:

Tom qab lub xeev-ntawm-tus-kos duab purification txheej txheem – high-pressure hydrofinishing, peb cov microcrystalline waxes zoo li tsis muaj impurities thiab paug dye. Cov qib siab ntawm hydrogenation ua kom nws cov purity siab thiab ua tau raws li cov kev cai ntawm purity cov cai, nrog rau lub ntiaj teb no pharmacopeia specifications, zaub mov specifications rau additives, zaub mov ntim, thiab cosmetic ntau lawm qauv.

Chemical Structure:

Microcrystalline wax yog ib qho sib xyaw molecular uas muaj ntau yam saturated hydrocarbon. Tsis zoo li paraffin wax, microcrystalline wax muaj ntau cov isoparaffins thiab naphthenes nrog ntev saw ceg.

Cov yam ntxwv ntawm kev ua tau zoo:

Microcrystalline Soft Waxes 7835 thiab 3971 yog ib feem ntawm kab ntawm hwm microcrystalline waxes rau kev lag luam tswm ciab nrog cov yam ntxwv hauv qab no:
1. Tsawg melting point thiab shrinkage tus nqi yog heev haum rau cov qauv txheej txheem ntawm khob ciab;
2. Cov qauv ntoo nplua nuj pab lub tswm ciab kaw cov roj thiab tswj cov paj;
3. Cov viscosity siab dua tuaj yeem ntxiv qhov feem ntau ntawm cov xibtes ciab rau cov qauv tswm ciab thiab txo cov nqi;
4. Kev hloov pauv tau zoo tuaj yeem ua rau cov qauv zoo nkauj tswm ciab thiab cov tswm ciab carved;
5. Muaj peev xwm tuav tau lub tswm ciab wick kom tiv thaiv cov xov paj tiav los ntawm tawg thiab tawg.

Certification:

Tshuaj pleev ib ce: Kev cai tshuaj pleev ib ce, EU Cosmetics Regulation (No. 1223/2009)
Kev Kho Tus Kheej: Pom Zoo Loj 14 Cov Khoom Siv Kho Hniav thiab Qhov Ncauj.
Khoom noj khoom haus additives: Lub teb chaws Yelemees (BfR Recommedation XXV.), European Union (PM Ref.No.95859; E905), United States (FDA 172.886)
Chaw muag tshuaj: EU (monograph npaj), Lub teb chaws Yelemees (DAC/Deutscher Arzneimittel-
Codex), USA (USP XXXI/NF 26: Microcrystalline wax)

Daim ntawv thov:

Microcrystalline waxes paub txog lawv ntau yam kev siv. Yuav siv tau los ua khoom siv tes ua tswm ciab, Vaseline, tshuaj pleev ib ce, sludge, khau polish, number case, explosive compound wax, mortar rau lub tsev cov ntaub ntawv, masterbatch ua, blending ntawm tshwj xeeb waxes, anti-xeb ciab, automotive ciab, emulsifying ciab, polishing ciab, pem teb ciab, hluav taws xob ciab, Glazing ciab, tiv thaiv tus neeg saib xyuas, txheej tus neeg saib xyuas, thickener, yooj yim raw khoom ntawm lubricant.
Cov kev tshawb fawb pom tau hais tias microcrystalline wax muaj kev nyab xeeb kiag li siv rau hauv kev lag luam khoom noj khoom haus thiab tau pom zoo siv los ua cov khoom noj ntxiv raws li EU tus qauv E905 qib. Hauv kev saib xyuas tus kheej, daim ntawv pov thawj no txhais tau hais tias microcrystalline waxes tuaj yeem siv ncaj qha rau hauv cov pos hniav hauv qab, cov khoom siv di ncauj (pom zoo los ntawm COLIPA), coatings, pwm tso cov neeg ua haujlwm, thiab ntau dua. Hauv lwm cheeb tsam, FDA cov qauv kuj siv tau. Nyob rau hauv cov tshuaj pleev ib ce thiab tshuaj formulations, microcrystalline waxes yog siv raws li inactives rau lwm yam khoom xyaw xws li petrolatum kom lipid theem ntawm emulsions thiab tshuaj pleev. Lawv yog siv los txhim kho cov roj nqus thiab ruaj khov kom haum rau qhov hardness ntawm formulation, los yog rau cov tawv tawv, cov roj sib xyaw nrog cov crystallinity tsawg. Microcrystalline waxes tuaj yeem txhim kho cov qauv thiab hardness ntawm kev zoo nkauj sticks xws li lipsticks yam tsis muaj crystallization ntau dhau.
Ntxiv me me ntawm microcrystalline wax rau paraffin, nws permeability tsis cuam tshuam. Feem ntau, txawm tias ib qho me me ntawm lwm cov tshuaj ntxiv ntxiv, cov quav ciab yuav dhau los ua opaque; ntxiv ib qho me me ntawm microcrystalline wax rau paraffin tuaj yeem txhim kho qhov kev tso tawm ntawm cov kua tsw qab, ua rau muaj kev cuam tshuam zoo rau cov wax crystallization, thiab txo qis thiab zam qhov tsis xav tau cov teebmeem snowflake; ntxiv microcrystalline wax rau lub khob siv quav ciab yuav ua rau lub hauv paus stick zoo rau lub khob.
