Product Description:
Glycerin, inozivikanwa se glycerol mumitemo yenyika, haina ruvara, isinganhuhwi, inotapira-munhuwiorganic substance ine chitarisiko chemvura inoonekera. Inonyanya kuzivikanwa se glycerol. Glycerol, inogona kutora hunyoro kubva mumhepo, asiwo inonwisa hydrogen sulfide, hydrogen cyanide uye sulfur dioxide.
Zvigadzirwa uye Kugadzikana:
1.Isina ruvara, yakajeka, isina kunhuhwirira, viscous liquid ine kutapira kunotapira uye hygroscopicity. Miscible nemvura uye doro, amines, phenols mune chero chikamu, aqueous mhinduro haina kwayakarerekera. Soluble in 11 times ethyl acetate, ingangoita 500 times ether. Haina kunyungudika mubenzene, chloroform, carbon tetrachloride, carbon disulfide, petroleum ethers, oiri, refu cheni ine mafuta doro. Inopisa, inogona kukonzera kupisa uye kuputika paunosangana neakasimba oxidising agents akadai sechromium dioxide uye potassium chlorate. Iyo zvakare inonyungudutsa yakanaka kune yakawanda inorganic munyu nemagasi. Isiri-inoodza kune simbi, inogona kuve oxidised kune acrolein kana yakashandiswa se solvent.
2.Chemical properties: esterification reaction with acid, yakadai nebenzene dicarboxylic acid esterification kugadzira alkyd resin. Transesterification reaction ne ester. Inogadzirwa nehydrogen chloride kugadzira doro rine chlorine. Glycerol dehydration ine nzira mbiri: intermolecular dehydration kuti uwane diglycerol uye polyglycerol; intramolecular dehydration kuti uwane acrolein. Glycerol inopindirana nemabhesi kuita zvidhakwa. Kuita nealdehydes uye ketoni kunogadzira acetals uye ketoni. Oxidation ine dilute nitric acid inoburitsa glyceraldehyde uye dihydroxyacetone; oxidation ne periodic acid inoburitsa formic acid uye formaldehyde. Nemaoxidants akasimba akadai sechromic anhydride, potassium chlorate kana potassium permanganate contact, inogona kukonzera kupisa kana kuputika. Glycerol inogona zvakare kuita basa re nitrification uye acetylation.
3.Non-chepfu. Kunyangwe kana huwandu hwese hwekunwa hunosvika 100g yemushonga we dilute haukuvadzi, mumuviri mushure me hydrolysis uye oxidation uye uve sosi yezvinovaka muviri. Mukuedza kwemhuka, ine imwechete anesthesia effect sedoro kana ichiitwa kunwa yakawanda kwazvo.
4.Inowanikwa mukubika fodya, fodya ine mbabvu chena, spice fodya, uye utsi hwefodya.
5.Inowanzoitika mufodya, doro, waini, cocoa.
Product Application:
1. Resin industry: inoshandiswa mukugadzira alkyd resin uye epoxy resin.
2. Indasitiri yekuputira: inoshandiswa mumhizha yekuputira kugadzira zvakasiyana-siyana zvealkyd resins, polyester resins, glycidyl ethers uye epoxy resins, nezvimwewo.
3. Textile uye kudhinda uye dhayi indasitiri: inoshandiswa kugadzira lubricant, mwando absorber, machira wrinkle-proof shrinkage treatment agent, diffusion agent uye inopinda mukati.
Nzira dzekuchengeta Chigadzirwa:
1. Chengetedza munzvimbo yakachena uye yakaoma, inofanira kubhadhara kune yakavharwa kuchengetedza. Chenjerera kune hunyoro-huchapupu, humbowo hwemvura, hunopisa, unorambidza zvachose kusanganiswa neakasimba oxidants. Inogona kuchengetwa mumatini-plated kana simbi isina tsvina.
2. Yakaiswa mumadhiramu ealuminium kana madhiramu esimbi kana kuchengetwa mumatangi akaiswa phenolic resin. Inofanira kuchengetedzwa kubva kune unyoro, kupisa uye mvura panguva yekuchengetedza uye kutakura. Zvinorambidzwa kuisa glycerol pamwe chete neakasimba oxidising agents (eg nitric acid, potassium permanganate, nezvimwewo). Inofanirwa kuchengetwa uye kutakurwa zvinoenderana neyakajairwa inopfuta kemikari mitemo.
Chigadzirwa Chekuchengetedza Notes:
1.Chengeta munzvimbo inotonhorera, ine mhepo yekuchengetera mhepo.
2.Gara kure nemoto uye kupisa sosi.
3.Chengetedza mudziyo wakavharwa.
4.Inofanira kuchengetwa zvakasiyana kubva kune oxidising agents, kuderedza vashandi, alkalis uye makemikari anodyiwa, usasanganise kuchengetedza.
5.Kushongedzwa nemhando dzakasiyana-siyana uye huwandu hwemidziyo yekudzivirira moto.
6.Nzvimbo yekuchengetera inofanira kunge yakashongedzerwa nekudonha kwechimbichimbi michina yekurapa uye yakakodzera pekugara zvinhu.
