Ethylene glycol, 1, 2-ethylenediol, EG kwenguva pfupi

makemikari maitiro

Chemical formula: (CH2OH)2 Molecular uremu: 62.068 CAS: 107-21-1 EINECS: 203-473-3 [5 Melting point: -12.9 ℃ Boiling point: 197.3 ℃

Kusuma chigadzirwa uye maitiro

CH2OH 2, inova iri nyore diol.Ethylene glycol imvura isina ruvara, isinganhuhwi, inotapira ine muchetura wakaderera kumhuka.Ethylene glycol inogona kunyungudika pamwe chete nemvura uye acetone, asi kunyungudika kwayo muether idiki.Inoshandiswa se solvent, antifreeze uye synthetic polyester raw material.Iyo polymer ye ethylene glycol, polyethylene glycol (PEG), idanho rekufambisa catalyst uye rinoshandiswawo musero fusion.

use

Inonyanya kushandiswa kugadzira polyester, polyester, polyester resin, kunyorova kwemvura, plasticizer, surface active agent, synthetic fiber, cosmetics uye zvinoputika, uye inoshandiswa se solvent yedhayi, ingi, nezvimwewo, kugadzirira injini antifreeze agent, gasi dehydrating agent, kugadzira resin, inogona zvakare kushandiswa kune cellophane, fiber, dehwe, adhesive wetting agent.Inogona kugadzira synthetic resin PET, fiber PET iri polyester fiber, bhodhoro slice PET yekugadzira mabhodhoro emvura yemamineral zvichingodaro.Inogonawo kugadzira alkyd resin, glyoxal, nezvimwewo, inoshandiswawo se antifreeze.Pamusoro pekushandiswa senge antifreeze yemotokari, inoshandiswa zvakare kutakura indasitiri yekutonhodza huwandu, inowanzodaidzwa kuti inotakura refrigerant, uye inogona zvakare kushandiswa seyakakwenenzverwa semvura.
Ethylene glycol methyl ether series zvigadzirwa zvemhando yepamusoro organic solvents, sekudhinda inki, indasitiri yekuchenesa agent, coating (nitro fiber pendi, varnish, enamel), ndiro yakavharwa nemhangura, kudhinda uye dhayi zvinonyungudutsa uye diluents;Inogona kushandiswa seyakabikwa yezvigadzirwa zvemakemikari senge pesticide intermediates, mishonga yepakati uye synthetic brake fluid.Se electrolytes ye electrolytic capacitors, kemikari fiber dyeing agent yekugadzira tanning, etc. Inoshandiswa semachira ebetsero, madhayi emagetsi ekugadzira, pamwe nefetereza nekuchenesa mafuta mukugadzira desulfurizer mbishi.
Ethylene glycol inofanira kucherechedzwa kana ichishandiswa semutakuri wefiriji:
1. Nzvimbo yechando inoshanduka nehuwandu hwe ethylene glycol mumushonga wemvura.Kana iyo yakasungwa iri pasi pe60%, nzvimbo yechando inoderera nekuwedzera kwehuwandu hwe ethylene glycol mune aqueous solution, asi kana iyo yakanyanyisa kupfuura 60%, nzvimbo yechando inowedzera nekuwedzera kwehuwandu hwe ethylene glycol, uye viscosity. inowedzera nekuwedzera kwehuwandu.Kana iyo yakasungwa inosvika 99.9%, kutonhora kwayo kunokwira kusvika -13.2 ℃, chiri chikonzero chakakosha nei concentrated antifreeze (antifreeze mai mvura) isingashandiswe zvakananga, uye inofanirwa kukwezva kutarisa kwemushandisi.
2. Ethylene glycol ine hydroxyl boka, iro richava oxidized ku glycolic acid uye ipapo kune oxalic acid, kureva, glycolic acid (oxalic acid), ine 2 carboxyl mapoka, apo inoshanda pa80-90 ℃ kwenguva yakareba.Oxalic acid uye zvigadzirwa zvayo zvinokanganisa kutanga kwepakati tsinga system, ipapo moyo, uyezve itsvo.Ethylene glycol glycolic acid, ichikonzera ngura uye kubuda kwemidziyo.Nokudaro, mukugadzirira kweantifreeze, panofanira kuva nekuchengetedza kudzivirira kuparara kwesimbi, aluminium uye kuumbwa kwechiyero.

pasuru uye chokufambisa

B. Ichi chigadzirwa chinogona kushandiswa,,25KG,200KG,1000KGBAERRLS.
C. Chengetedza chakavharwa munzvimbo inotonhorera, yakaoma uye inofefetera mukati memba.Midziyo inofanira kuvharwa zvakasimba mushure mekushandiswa kwega kwega isati yashandiswa.
D. Ichi chigadzirwa chinofanira kuiswa chisimbiso zvakanaka panguva yekufambisa kudzivirira unyoro, alkali yakasimba uye asidi, mvura uye zvimwe tsvina kubva pakusanganiswa.
