Mono propylene Glycol
Khoom Description
Nws yog cov kua xim tsis muaj xim nrog cov viscosity ruaj khov thiab nqus dej zoo.
Nws yog ze li odorless, uninflammable thiab minutely toxic. Nws molecular mass yog 76.09. Nws cov viscosity (20oC), lub peev xwm tshwj xeeb kub (20oC) thiab latent cua sov ntawm vaporization (101.3kpa) yog feem 60.5mpa.s, 2.49KJ / (kg. oC) thiab 711KJ / kg.
Nws tuaj yeem sib xyaw thiab daws nrog cawv, dej thiab ntau yam khoom siv organic.
Propylene Glycol yog cov khoom siv raw rau kev npaj unsaturated polyester cob, plasticizer, nto active tus neeg sawv cev, emulsifying tus neeg saib xyuas thiab demulsifying tus neeg saib xyuas.
Nws kuj tseem siv tau los ua pwm inhibitor, tshuaj tua kab mob rau cov txiv hmab txiv ntoo, dej khov inhibitor thiab cov dej khaws cia rau cov luam yeeb.

Daim ntawv thov
(1) Propylene glycol yog siv los ua raw cov ntaub ntawv rau resins, plasticizers, surfactants, emulsifiers thiab demulsifiers, nrog rau cov tshuaj tiv thaiv kab mob thiab cov cua sov.
(2) Propylene glycol yog siv los ua cov roj chromatography nyob ruaj ruaj, kuab tshuaj, tshuaj tiv thaiv kab mob, plasticizer thiab dehydrating agent.
(3) Propylene glycol feem ntau yog siv rau kev tshem tawm cov kuab tshuaj ntawm ntau yam txuj lom, pigments, preservatives, vanilla taum, roasted kas fes granule, ntuj tsw thiab lwm yam. Moisturizing thiab softening tus neeg sawv cev rau khoom qab zib, qhob cij, ntim cov nqaij, cheeses, thiab lwm yam.
(4) Nws tseem tuaj yeem siv los ua tus neeg sawv cev tiv thaiv kab mob rau noodle thiab sau cov tub ntxhais. Ntxiv 0.006% rau cov kua mis, uas tuaj yeem ua rau qhov tsw tsis hloov pauv thaum cua sov, thiab ua kom dawb thiab glossy ntim taum curd.
