Daim ntawv thov
Didipropylene glycol yog ib qho dej cawv organic, uas feem ntau yog siv hauv cov teb uas xav tau cov ntaub ntawv zoo xws li cov txuj lom, tshuaj pleev ib ce, tshuaj ntxuav tes thiab khoom noj khoom haus ntxiv.Cov tom kawg yog tus nqi qis, thiab tau dav siv los ua cov kuab tshuaj uas tsis tas yuav tsum tau zoo ntawm DPG, nrog rau cov khoom siv raw rau kev tsim cov kua roj vanish tsis muaj polyester thiab nitrocellulose.

(1) Dipropylene glycol yog cov kuab tshuaj zoo tshaj plaws rau ntau cov tshuaj tsw qab thiab tshuaj pleev ib ce.Cov khoom siv raw no muaj cov dej zoo heev, roj thiab hydrocarbon co-solubility thiab muaj cov ntxhiab tsw me me, qhov khaus tawv nqaij tsawg, tsis muaj tshuaj lom, tsis sib xws isomer faib thiab zoo heev.
(2) Dipropylene glycol kuj tseem siv tau los ua tus neeg sawv cev sib txuas thiab tus neeg saib xyuas moisturizing hauv ntau daim ntawv thov kom zoo nkauj.Hauv perfumery, dipropylene glycol yog siv ntau tshaj 50%;Hauv qee qhov kev siv, dipropylene glycol feem ntau siv tsawg dua 10% los ntawm qhov hnyav.Qee cov khoom siv tshwj xeeb suav nrog: cov plaub hau curling lotions, cov tshuaj ntxuav tawv nqaij (cov tshuaj txias txias, ntxuav lub cev, da dej thiab tshuaj pleev lub cev) deodorants, ntsej muag, tes thiab lub cev cov khoom tu tawv nqaij, cov khoom tu tawv nqaij moisturizing thiab di ncauj balms.

Kev npaj: Hauv 5L cov tshuaj tiv thaiv kettle, ntxiv 30g ntawm sodium methanol, 750g ntawm propylene oxide thiab 2250g ntawm propylene glycol li alkali catalyst, them nitrogen rau 0.3MPa, tig rau nplawm, kub txog 110 ℃ hauv 30 feeb, maj mam tso nitrogen thaum lub sij hawm. cov txheej txheem cua sov, khaws lub siab nyob rau hauv lub hwj ntawm 0.3MPa thaum cua sov mus txog 120 ℃ hauv Chemicalbook, cov tshuaj tiv thaiv lub sij hawm 2 teev.Tom qab cov tshuaj tiv thaiv tiav lawm, txias thiab nias tawm cov khoom ua kua hauv lub hwj.Cov khoom siv tshuaj tiv thaiv tau txheeb xyuas los ntawm cov pa roj chromatography thiab purity ntawm cov khoom yog 99.87%;Qhov khov ntawm cov khoom tau txais nyob rau hauv cov xwm txheej ntawm alkaline catalyst yog 4 ℃.
