Mono Propylene Glycol
Huahana Huahana
He wai waihoʻoluʻu me ka viscosity paʻa a me ka lawe wai maikaʻi.
ʻAneʻane ʻaʻohe ona, ʻaʻole hiki ke ʻaʻa a me ka ʻawaʻawa. ʻO 76.09 kona nui mole. Kona viscosity (20oC), kiko'ī wela mana (20oC) a me ka latent wela o vaporization (101.3kpa) pakahi 60.5mpa.s, 2.49KJ/(kg. oC) a me 711KJ/kg.
Hiki ke hoʻohui ʻia a hoʻonā ʻia me ka waiʻona, ka wai a me nā ʻano mea ola like ʻole.
ʻO Propylene Glycol ka mea maka no ka hoʻomākaukau ʻana i ka resin polyester unsaturated, plasticizer, surface active agent, emulsifying agent a me demulsifying agent.
Hiki ke hoʻohana ʻia e like me ka mold inhibitor, antiseptic no ka huaʻai, hau inhibitor a me ka moisture preserving agent no ka paka.

Palapala noi
(1) Hoʻohana ʻia ʻo propylene glycol e like me nā mea maka no nā resins, plasticizers, surfactants, emulsifiers a me demulsifiers, a me ka antifreeze a me nā mea lawe wela.
(2) Hoʻohana ʻia ka propylene glycol e like me ke kinoea chromatography stationary wai, solvent, antifreeze, plasticizer a me ka mea hoʻoheheʻe wai.
(3) Hoʻohana nui ʻia ka propylene glycol no ka wehe ʻana i ka solvent o nā mea ʻala like ʻole, nā puaʻa, nā preservatives, vanilla bean, kope kope granule, ʻono maoli a pēlā aku. He mea hoʻomaʻemaʻe a palupalu no ka lole, ka berena, ka ʻiʻo i hoʻopaʻa ʻia, ka paʻakai, etc.
(4) Hiki ke hoʻohana ʻia ma ke ʻano he anti - mildew agent no ka noodle a me ka hoʻopiha piha. E hoʻohui i ka 0.006% i ka waiū soy, hiki ke hoʻololi ʻole i ka ʻono i ka wā e hoʻomehana ai, a hana i ke keʻokeʻo a me ka ʻālohilohi paʻa pī.
