Fa'atomuaga oloa ma foliga

CH2OH 2, o le diol sili ona faigofie.Ethylene glycol o se vai e leai se lanu, e leai se manogi, suamalie suamalie e maualalo le oona i manu.O le Ethylene glycol e mafai ona solu faatasi i le vai ma le acetone, ae o lona soluble i ethers e laʻititi.Fa'aaogaina e fai ma solvent, antifreeze ma synthetic polyester raw material.O le polymer o le ethylene glycol, polyethylene glycol (PEG), o se faʻaliliuga faʻasolosolo vaega ma faʻaaogaina foi i le fusuaga sela.

fa'aoga

E masani ona faʻaaogaina mo le faia o le polyester, polyester, polyester resin, susu faʻafefe, plasticizer, mea faʻamalosi i luga, fiber synthetic, mea teuteu ma mea pāpā, ma faʻaaogaina e avea o se solvent mo vali, inks, ma isi. gaosiga resin, e mafai foi ona faaaoga mo cellophane, alava, paʻu, pipii susu susua sui.E mafai ona gaosia resin resin PET, fiber PET o le polyester fiber, atigi fagu PET mo le faia o fagu vai minerale ma isi.E mafai foi ona gaosia alkyd resin, glyoxal, ma isi, faʻaaogaina foi e fai ma antifreeze.I le faaopoopo atu i le faʻaaogaina e fai ma antifreeze mo taavale, e faʻaaogaina foi mo le felauaiga o le faʻamafanafanaga o fale gaosi oloa, e masani ona taʻua o le pusaaisa, ma e mafai foi ona faʻaaogaina e pei o le condensing agent e pei o le vai.
Ethylene glycol methyl eter faasologa oloa o solvents organic tulaga maualuga, e pei o le lomitusi vaitusi, fale gaosi oloa faamamaina, ufiufi (nitro fiber vali, varnish, enamel), apamemea ufiufi ipu, lomitusi ma vali solvents ma diluents;E mafai ona fa'aaogaina e fai ma mea mata mo oloa fa'ama'i e pei o vaila'au fa'alatalata, vaila'au vaila'au ma vaila'au fa'apipi'i.E pei o electrolytes mo capacitors electrolytic, vailaʻau filo vali vailaʻau mo tanning, ma isi. Faʻaaogaina e pei o auxiliaries textile, synthetic vai vali, faʻapea foʻi ma fetilaisa ma suauu faamamaina i le gaosiga o desulfurizer mea mata.
E tatau ona maitauina le Ethylene glycol pe a faʻaaogaina e fai ma pusa faʻaisa:
1. O le mea malulu e suia i le faʻaogaina o le ethylene glycol i le vai vai.A oʻo i lalo ifo o le 60% le faʻamaualuga, e faʻaitiitia le faʻamalo i le faʻateleina o le faʻaogaina o le ethylene glycol i le vai vaifofo, ae a sili atu le maualuga o le 60%, e faʻatuputeleina le faʻamalo i le faʻateleina o le faʻaogaina o le ethylene glycol, ma le viscosity. faʻateleina i le faʻateleina o le faʻatonuga.A oʻo atu le faʻatonuga i le 99.9%, o lona tulaga malulu e oʻo atu i le -13.2 ℃, o se mafuaʻaga taua lea e le mafai ai ona faʻaogaina saʻo le antifreeze faʻamalosi (antifreeze mother liquid), ma e tatau ona tosina mai ai le mafaufau o le tagata faʻaoga.
2. Ethylene glycol o loʻo i ai le vaega hydroxyl, lea o le a faʻamaʻiina i le glycolic acid ona sosoo ai lea ma le oxalic acid, o lona uiga, glycolic acid (oxalic acid), o loʻo i ai vaega 2 carboxyl, pe a galue i le 80-90 ℃ mo se taimi umi.Oxalic acid ma ona mea e maua mai ai e aafia muamua ai le fatugalemu, sosoo ai ma le fatu, ona sosoo ai lea ma fatugaʻo.Ethylene glycol glycolic acid, e mafua ai le pala ma le tafe o meafaigaluega.O le mea lea, i le sauniuniga o le antifreeze, e tatau ona i ai se faʻasao e puipuia ai le pala o le sila, alumini ma le faʻavaeina o fua.

afifi ma felauaiga

B. O lenei oloa e mafai ona faʻaaogaina,, 25KG, 200KG, 1000KGBAERRLS.
C. Teu fa'amaufa'ailoga i se nofoaga mālūlū, mago ma fa'alili i totonu.O koneteina e tatau ona fa'amaufa'ailoga lelei pe a uma fa'aoga ta'itasi a'o le'i fa'aogaina.
D. O lenei oloa e tatau ona faʻamaufaʻailogaina lelei i le taimi o felauaiga e puipuia ai le susu, malosi alkali ma acid, timu ma isi mea leaga mai le faʻafefiloi.
