Propylene glycol inoshandiswa kuita zvakafanana nemamwe maglycols.
Propylene glycol chinhu chakakosha mbishi ye polyester isina unsaturated, epoxy resin, uye polyurethane resin.Nhamba yekushandiswa munzvimbo ino inokwana 45% yehuwandu hwekushandiswa kwepropylene glycol.Polyester yakadaro isina unsaturated inoshandiswa zvakanyanya kune yakasimbiswa mapurasitiki uye pamusoro pekuvhara.Propylene glycol yakanakisa mu viscosity uye hygroscopicity uye haina chepfu, uye nekudaro inoshandiswa zvakanyanya se hygroscopic agent, antifreeze, lubricant uye zvinonyungudutsa muindasitiri yezvekudya, mishonga uye cosmetic.Muchikafu chekudya, propylene glycol inopindirana nemafuta acid kuti ipe propylene ester yemafuta acids, uye inonyanya kushandiswa sekudya emulsifier;Propylene glycol inonyungudutsa yakanaka yekunhuhwirira uye pigment.Propylene glycol inowanzoshandiswa sezvinonyungudutsa, zvinyoro-nyoro uye zvinobatsira, nezvimwewo muindasitiri yemishonga yekugadzira marudzi akasiyana-siyana ekuzora uye salves.Propylene glycol inoshandiswawo sechinhu chinonyungudutsa uye chinopfavisa cosmetic sezvo iine yakanaka kunyungudika pamwe nezvinonhuwira zvakasiyana.Propylene glycol inoshandiswawo sefodya moisturizing agents, antifungal agents, mafuta ekugadzira chikafu uye zvinonyungudutsa zvekumaka inki yechikafu.Aqueous solution yepropylene glycol inonyatsoshanda anti-freeze agent.
Padivi pemvura, propylene glycol ndiyo inonyanya kutakura mvura inotakura mota inoshandiswa mukugadzira zvizorwa.Iine ganda riri nani kupfuura glycerin, uye rinopawo kunzwa kunofadza nemafuta mashoma kupfuura glycerin.Propylene glycol inoshandiswa sehumectant nokuti inotora mvura kubva mumhepo.Inoshandawo se solvent ye anti-oxidants uye preservatives.Pamusoro pezvo, ine zvigadziriso zvinodzivirira kurwisa mabhakitiriya uye fungi kana ichishandiswa muzvikamu zve16 muzana kana kupfuura.Pane kunetsekana kuti propylene glycol inotsamwisa pakakwirira, kunyange ichiita seyakachengetedzeka pamazinga ekushandiswa pasi pe5 muzana.
Propylene Glycol is humectant uye flavour solvent iyo iri polyhydric doro (polyol).imvura yakachena, ine viscous ine kunyungudika kwakakwana mumvura pa20°c uye kunyungudika kwemafuta.inoshanda sehumectant, sezvinoita glycerol uye sorbitol, mukuchengetedza hunyoro hunodiwa uye kugadzirwa muzvokudya zvakadai se shredded coconut uye icings.inoshanda sechinhu chinonyungudutsa chekunhuhwirira uye mavara asinganyungudika mumvura.inoshandiswawo muzvinwiwa nezvihwitsi.
