Sumo yechigadzirwa uye maficha azvo

CH2OH 2, inova diol iri nyore. Ethylene glycol imvura isina ruvara, isinganhuwi, inotapira uye ine chepfu shoma kumhuka. Ethylene glycol inogona kunyungudika pamwe chete nemvura neacetone, asi kunyungudika kwayo mu ethers kudiki. Inoshandiswa se solvent, antifreeze uye synthetic polyester raw material. Polymer ye ethylene glycol, polyethylene glycol (PEG), imhando ye phase transfer catalyst uye inoshandiswawo mu cell fusion.

shandisa

Inonyanya kushandiswa kugadzira polyester, polyester, polyester resin, inonwisa hunyoro, plasticizer, surface active agent, synthetic fiber, cosmetics uye zvinoputika, uye inoshandiswa se solvent yedhayi, inki, nezvimwewo, kugadzirira injini antifreeze agent, gas dehydrating agent, kugadzira resin, inogonawo kushandiswa cellophane, fiber, dehwe, adhesive wetting agent. Inogona kugadzira synthetic resin PET, fiber PET inonzi polyester fiber, bottle slice PET yekugadzira mabhodhoro emvura ane mineral nezvimwewo. Inogona zvakare kugadzira alkyd resin, glyoxal, nezvimwewo, inoshandiswawo se antifreeze. Kuwedzera pakushandiswa se antifreeze yemotokari, inoshandiswawo kutakura simba rekutonhodza reindasitiri, rinowanzonzi carrier refrigerant, uye inogonawo kushandiswa se condensing agent semvura.
Zvigadzirwa zveEthylene glycol methyl ether series solvents dzemhando yepamusoro, se inki yekudhinda, mushonga wekuchenesa weindasitiri, coating (nitro fiber pendi, varnish, enamel), coated plate yemhangura, printing and dyeing solvents uye diluents; Inogona kushandiswa sezvinhu zvekugadzira makemikari akadai semishonga inouraya zvipembenene, mishonga inouraya zvipembenene uye synthetic brake fluid. Se electrolytes ye electrolytic capacitors, chemical fiber dyeing agent yekuchenesa ganda, nezvimwewo. Inoshandiswa semachira ekubatsira, madhayi emvura anogadzirwa, pamwe nefetereza nemafuta ekuchenesa mukugadzira desulfurizer raw materials.
Ethylene glycol inofanira kucherechedzwa kana ichishandiswa semuchina wekutakura zvinhu mufiriji:
1. Nzvimbo yekuomesa inochinja nekuwanda kwe ethylene glycol mumushonga wemvura. Kana huwandu hwacho huri pasi pe60%, nzvimbo yekuomesa inoderera nekuwanda kwe ethylene glycol mumushonga wemvura, asi kana huwandu hwacho hwapfuura 60%, nzvimbo yekuomesa inowanda nekuwanda kwe ethylene glycol, uye viscosity inowanda nekuwanda kwehuwandu. Kana huwandu hwacho hwasvika 99.9%, nzvimbo yayo yekuomesa inokwira kusvika -13.2℃, inova chikonzero chakakosha nei antifreeze yakakamurwa (antifreeze mother liquid) isingakwanise kushandiswa zvakananga, uye inofanira kukwezva kutariswa kwemushandisi.
2. Ethylene glycol ine hydroxyl group, iyo inozogadziriswa kuita glycolic acid uye yozopedzisira yava oxalic acid, kureva glycolic acid (oxalic acid), ine mapoka maviri ecarboxyl, kana ikashanda pa80-90 ℃ kwenguva yakareba. Oxalic acid nezvimwe zvinogadzirwa nayo zvinotanga kukanganisa sisitimu yetsinga huru, kwozotevera mwoyo, uye kwozotevera itsvo. Ethylene glycol glycolic acid, zvichikonzera ngura nekubuda kwemidziyo. Saka, pakugadzirira antifreeze, panofanira kunge paine chinhu chinochengetedza ngura yesimbi, aruminiyamu uye kuumbwa kwechiyero.

pasuru uye kutakurwa

B. Chigadzirwa ichi chinogona kushandiswa,,25KG，200KG,1000KGBAERRLS。
C. Chengeta yakavharwa munzvimbo inotonhorera, yakaoma uye ine mhepo mukati. Midziyo inofanira kuvharwa zvakasimba mushure mekushandisa kwega kwega usati washandisa.
D. Chigadzirwa ichi chinofanira kuvharwa zvakanaka panguva yekufambisa kudzivirira hunyoro, alkali yakasimba uye acid, mvura nezvimwe tsvina kuti zvisasanganiswe.
