Nhanganyaya
Mvura isina ruvara, isinganhuhwi, yakajeka, ine hygroscopic viscous fluid. Ine spicy kutapira. Kunyungudika kwayo kwakafanana neye ethylene glycol, asi kunyungudika kwayo kumahydrocarbons kwakasimba. Diethylene glycol inogona kuva miscible nemvura, ethanol, ethylene glycol, acetone, chloroform, furfural, etc. It is immiscible with ether, carbon tetrachloride, carbon disulfide, straight chain aliphatic hydrocarbon, aromatic hydrocarbon, etc. Rosin, shellac, cellulose acetate, cellulose acetate, etc. uye mafuta mazhinji haagadzirike mudiethylene glycol, asi anogona kunyungudutsa cellulose nitrate, alkyd resins, polyester resins, polyurethane, uye akawanda madhayi. Inopisa, yakaderera chepfu. Kuve neyakajairwa kemikari zvimiro zvedoro uye ether.
Kuchengeta Nzira
1. Chengetedza munzvimbo inotonhorera uye yakaoma. Ita shuwa kuti muwekishopu mune mhepo yakanaka.
2. Ramba kure nemoto nemvura. Chengetedza kure neoxidants
Shandisa
1. Inonyanya kushandiswa segasi dehydrating agent uye aromatics extraction solvent. Inoshandiswawo se solvent ye cellulose nitrate, resin, girisi, inki yekudhinda, textile softener, finishing agent, uye kubvisa coumarone uye indene kubva marasha tara. Uye zvakare, diethylene glycol inoshandiswawo senge brake oil complex, celluloid softener, antifreeze uye diluent mu emulsion polymerization. Uyewo inoshandiswa kune rabha uye resin plasticizer; Polyester resin; Fiberglass; Carbamate foam; Kugadzirwa kwemafuta ekuzora viscosity inovandudza uye zvimwe zvigadzirwa. Inoshandiswa kugadzira unsaturated polyester resin, nezvimwe.
2. Inoshandiswa se synthetic unsaturated polyester resin, plasticizer, etc. Inoshandiswawo se antifreeze, gas dehydrating agent, plasticizer, solvent, aromatics extraction agent, cigarette hygroscopic agent, textile lubricant uye finishing agent, paste nemhando dzose dzeadhesive anti-drying agent. , VAT dye hygroscopic solvent, etc. Iyo inowanzogadziriswa yemafuta, resin uye nitrocellulose.
