Te tātai matū: (CH2OH)2 Te taumaha o te rāpoi: 62.068 CAS: 107-21-1 EINECS: 203-473-3 [5 Wāhi whakarewa: -12.9 ℃ Ira kohua: 197.3 ℃

Whakataki hua me nga ahuatanga

CH2OH 2, ko te diol ngawari rawa atu.Ko te Ethylene glycol he wai kore tae, he kakara, he wai reka he iti te paitini ki nga kararehe.Ka taea e te Ethylene glycol te whakarewa tahi ki te wai me te acetone, engari he iti tona whakarewanga ki te eter.Ka whakamahia hei whakarewa, hei whakakao me te polyester raw rauemi.Ko te polymer o te ethylene glycol, polyethylene glycol (PEG), he whakakōkī whakawhiti wāhanga, ā, ka whakamahia hoki ki te whakakotahitanga pūtau.

whakamahi

Te nuinga whakamahia mo te hanga polyester, polyester, polyester resin, makuku absorbent, plasticizer, māngai hohe mata, muka waihanga, poke me explosives, a ka whakamahia hei whakarewa mo nga waikano, waituhi, me etahi atu, te whakarite mo te miihini antifreeze kaihoko, te kaihoko hau hau, whakangao kapia, ka taea hoki te whakamahi mo te cellophane, te muka, te hiako, te kaihoko makuku whakapiri.Ka taea e ia te whakaputa kapia waihanga PET, te muka PET he muka polyester, te tapatapahi pounamu PET mo te hanga ipu wai kohuke me etahi atu.Ka taea hoki te whakaputa kapia alkyd, glyoxal, me etahi atu, ka whakamahia ano hei antifreeze.I tua atu i te whakamahia hei antifreeze mo nga motuka, ka whakamahia ano hoki mo te kawe i te kaha whakamahana ahumahi, e kiia ana ko te kaikawe kaikawe, ka taea hoki te whakamahi hei kaihoko whakamaarama penei i te wai.
Ko nga hua raupapa Ethylene glycol methyl ether he whakarewa pararopi o te kounga teitei, penei i te waituhi ta, te horoi horoi ahumahi, te paninga (peita muka nitro, te varnish, te tohu tohu), te pereti whakakikorua ki te parahi, te whakaputa me te waikano whakarewa me nga wairewa;Ka taea te whakamahi hei rauemi mata mo nga hua matū penei i te takawaenga pesticide, takawaenga ho'oraa me te wai parai waihanga.Ka rite ki te electrolytes mo te hiko hiko, te muka matū kai tae mo te tanning, me etahi atu Ka whakamahia hei awhina pueru, waikano wai waihanga, tae atu ki te tongi me te hinu para i roto i te hanga o nga rauemi mata desulfurizer.
Me tohuhia te Ethylene glycol ina whakamahia ana hei whakamahana kawe:
1. Ka huri te ira mīti ki te kukū o te ethylene glycol i roto i te wairewa wai.Ka iti iho te kukū ki te 60%, ka heke te ira mīti i te pikinga o te kukū o te ethylene glycol i roto i te wairewa wai, engari ki te neke ake te kukū ki te 60%, ka piki te ira mīti ki te pikinga o te kukū o te ethylene glycol, me te viscosity. ka piki me te piki o te kukū.Ka tae te kukū ki te 99.9%, ka piki tona ira mīti ki te -13.2 ℃, he take nui e kore e taea te whakamahi tika i te antifreeze concentrated (antifreeze mother liquid), a me kukume te aro o te kaiwhakamahi.
2. Kei roto i te Ethylene glycol te roopu hydroxyl, ka oxidized ki te waikawa glycolic me te waikawa oxalic, ara, te waikawa glycolic (waikawa oxalic), kei roto e 2 nga roopu carboxyl, ka mahi i te 80-90 ℃ mo te wa roa.Ko te waikawa Oxalic me ona hua ka pa i te tuatahi ki te punaha io matua, katahi ko te ngakau, katahi ko nga whatukuhu.Ko te waikawa Ethylene glycol glycolic, na te waikura me te pakaru o nga taputapu.Na reira, i roto i te faaineineraa o te antifreeze, me waiho he kaitiaki hei aukati i te pirau o te maitai, te konumohe me te hanganga o te tauine.

mōkihi me te kawe

B. Ka taea te whakamahi i tenei hua, 25KG, 200KG, 1000KGBAERRLS.
C. Roakina kua hiritia ki te waahi matao, maroke me te whai hau i roto i te whare.Me tino hiri nga ipu i muri i ia whakamahinga i mua i te whakamahinga.
D. Me pai te hiri o tenei hua i te wa e kawe ana kia kore ai te makuku, te kawakawa kaha me te waikawa, te ua me etahi atu poke kia kore e uru.
