1,2-Propylene Glycol CAS NO.57-55-6
Products Description
- 1,2 Propylene glycol yepakati yebactericide difenoconazole uye yakakosha mbishi ye polyester isina unsaturated, epoxy resin, uye polyurethane resin. Mari iri muchikamu ichi inosvika makumi mana neshanu muzana yehuwandu hwekushandisa kwe1,2 propylene glycol. Iyi unsaturated poly Ester inoshandiswa zvakanyanya mumachira epamusoro uye mapurasitiki akasimbiswa. 1,2 Propylene glycol ine viscosity yakanaka uye hygroscopicity, uye haina chepfu, saka inoshandiswa zvakanyanya seyakanyorovesa, antifreeze, lubricant uye solvent mumaindasitiri ezvekudya, mishonga uye cosmetic. Muindasitiri yezvekudya, inonyanya kushandiswa sekudya emulsifier; panguva imwechete iyo inonyungudutsa yakanakisa yemwaka uye pigments.
- Iyo yekubvisa maitiro e1,2 propylene glycol ndeye tekinoroji munda wekuparadzaniswa kwemakemikari. Iyi nzira inoshandisa hunhu hwekuti mineral acid munyu zviri nyore kupenya, nepo organic acid munyu mupropylene glycol fermentation muto haisi nyore kupenya. Huwandu hwakakodzera hweasidhi yeasidhi inowedzerwa kune propylene glycol fermentation muto kutsiva iyo organic acid munyu mumuto wekuvirisa neorganic acids. Iyo inoenderana mineral acid munyu inogadzirwa; iyo fermentation broth yakanyanyisa, kuitira kuti mineral acid salt crystallizes, uye inoparadzaniswa nemuto wekuvirisa; iyo concentrated fermentation broth inova propylene glycol, succinic acid, lactic acid, acetic acid, glycerol uye 2,3-butane Musanganiswa wedoro, vacuum distillation yemusanganiswa kuwana zvigadzirwa zvechikamu chimwe nechimwe. Muindasitiri yemishonga, propylene glycol inowanzoshandiswa sechinhu chinonyungudutsa, chinopfavisa uye chinobatsira pakugadzirwa kwemafuta ekuzora akasiyana siyana. Nemhaka yekuenderana kwayo kwakanaka nezvinonhuwira zvakasiyana-siyana, inoshandiswawo sechinhu chinonyungudutsa uye chinopfava chezvizoro.Propylene glycol inoshandiswawo sefodya moisturizer, antifungal agent, chikafu chekugadzira midziyo yekuzora mafuta uye chikafu chekumaka inki solvent. Mushonga wemvura wepropylene glycol unoshanda antifreeze.
