Monoethylene Glycol (MEG)—ethylene glycol e hloekileng ea 99.9%—ke thepa ea bohlokoa ea lik'hemik'hale tse tala indastering ea sejoale-joale. Joaloka moetsi le mofani ea tšepahalang ea lulang Chaena, Shandong Aojin Chemical e inehetse ho tloha ha e thehoa ka 2009 ho fa bareki ba lefats'e ka bophara lihlahisoa tsa MEG tse hloekileng haholo, litharollo tse tsitsitseng tsa ketane ea phepelo, le litheko tse hlōlisanang haholo. Re tšehelitsoe ke taolo e matla ea boleng, lits'ebetso tse tsoetseng pele tsa tlhahiso, le boiphihlelo bo bongata ba indasteri, re fetohile molekane ea tšepahalang bakeng sa likhoebo ho pholletsa le makala a masela, a liphutheloana, a likoloi le a tlhahiso ea lik'hemik'hale.
Monoethylene Glycol (MEG) ke eng?
Monoethylene Glycol (MEG), e nang le foromo ea lik'hemik'hale ea C₂H₆O₂ le nomoro ea CAS 107-21-1, ke diol e bonolo ka ho fetisisa. E khetholloa ka ho feto-fetoha ho tlase, viscosity e phahameng, le ho kopana ho hoholo ha metsi, ethanol le li-solvents tse fapaneng tsa tlhaho. Jwalo ka mofuta o ka sehloohong oa sehlahisoa sa ethylene glycol, MEG e ikarabella bakeng sa ho feta 90% ea 'maraka oohle oa ethylene glycol' me e sebetsa e le thepa ea motheo e tala bakeng sa lits'ebetso tse ngata tsa indasteri.
MEG ea bohloeki ea 99.9% e hlahisoang ke Shandong Aojin Chemical e etsoa ka ho sebelisa lits'ebetso tse tsoetseng pele tsa petrochemical, ho netefatsa boemo ba bohloeki ba bonyane 99.9%. Litlhaloso tsa bohlokoa tsa tekheniki ke tse latelang:
Bohloeki: ≥99.9%
Metsi a teng: ≤0.05%
Asiti: ≤0.001%
'Mala: ≤5 Hazen
Botenya (20°C): 1.1132 g/cm³
Boemo ba ho belisa: 197.3°C
Sebaka sa ho qhibiliha: -12.9°C
Sehlahisoa sena se hloekileng haholo se fihlela maemo a boleng ba faeba le a indasteri mme se tsamaisana ka botlalo le thepa ea MEG e tsoang kantle ho naha, se netefatsa kopanyo e se nang sekoli lits'ebetsong tsa tlhahiso ea indasteri.
Tšebeliso ea Ethylene Glycol (MEG)
Monoethylene Glycol (MEG) ke k'hemik'hale ea indasteri e feto-fetohang e nang le mefuta e mengata ea lits'ebetso makaleng a fapaneng, e leng se susumetsang kholo ea tlhoko ea lefats'e.
1. Indasteri ea Polyester le Masela (Sebaka se Seholo ka ho Fetisisa sa Tšebeliso)
Ho feta 60% ho isa ho 70% ea tlhoko ea lefats'e ea MEG e bakoa ke tlhahiso ea faeba ea polyester. Ethylene glycol e nang le bohloeki ba 99.9% e arabela le terephthalic acid e hloekisitsoeng (PTA) ho hlahisa polyethylene terephthalate (PET), e leng thepa ea mantlha ea masela a polyester, liaparo, masela a lapeng le masela a indasteri. MEG e hloekileng haholo e netefatsa boleng bo tsitsitseng ba khoele, e fokotsa liphoso tsa masela, 'me e ntlafatsa katleho ea tlhahiso.
2. Liphutheloana le Lifilimi tsa Liphoofolo tse Ruuoang
MEG ke thepa ea bohlokoa bakeng sa ho hlahisa libotlolo tsa PET (bakeng sa lino, metsi a liminerale le litlolo), lifilimi tsa ho paka lijo le maqephe a indasteri. Bohloeki ba eona bo phahameng bo netefatsa polokeho, ponaletso le ho tšoarella ha thepa ea ho paka ha e ntse e fihlela maemo a ho kopana le lijo.
3. Di-antifreeze tsa dikoloi le di-coolant
Jwalo ka karolo ya bohlokwa ya antifreeze ya enjene, ethylene glycol e fokotsa ntlha ya ho hoama ya ditharollo tse thehilweng metsing, e thibela enjene ho hoama mariha kapa ho chesa haholo hlabula. E boetse e sireletsa sistimi ya ho phodisa kgahlanong le mafome le ho bokellana ha sekala, ka hona e eketsa nako ya bophelo ba enjene. MEG ya rona ya bohloeki ba 99.9% ke kgetho e ntle bakeng sa ho etsa dihlahiswa tsa antifreeze tse sebetsang hantle.
4. Dikhemikhale tse Mahareng le Disolvent tsa Diindasteri
MEG ke sesebelisoa sa bohlokoa bakeng sa ho etsa li-resin, likhomaretsi, pente ea latex, li-emulsion tsa asphalt, le li-capacitor tsa electrolytic. Masimong a tlhahiso ea lik'hemik'hale, liphahlo le ts'ebetso ea letlalo, e sebelisoa khafetsa e le moemeli oa humectant, solvent, le coupling.
5. Likopo tse ling tsa indasteri
Metsi a tlosang leqhoa bakeng sa lifofane le litsela tsa ho matha
Li-humectant bakeng sa pampiri le letlalo
Lisebelisoa tse tala bakeng sa li-surfactants le litlolo
Li-coolant bakeng sa litsamaiso tsa sehatsetsi tsa indasteri
Hobaneng o ka Khetha Shandong Aojin Chemical e le ea Hao?Mofani oa Ethylene Glycol?
1. Boleng bo Phahameng: E Tiisitsoe Bohloeki ba 99.9%
Jwalo ka moetsi wa profeshenale wa ethylene glycol, dihlahiswa tsa rona tsa MEG di fihlela maemo a indasteri ka dinako tsohle kapa di feta maemo a tsona, di boloka bohloeki bo tsitsitseng ba ≥99.9%. Sehlopha se seng le se seng se tla le Setifikeiti sa Tlhahlobo (COA) ho netefatsa tshebetso e tshepahalang dikopong tsa hao.
2. Phepelo e Tsitsitseng le Bokgoni bo Matla ba Tlhahiso
Re tšehelitsoe ke bokhoni bo matla ba tlhahiso le sistimi e felletseng ea ketane ea phepelo, re boloka lethathamo le lekaneng la thepa ho fihlela litlhoko tsa liodara tse kholo le tse potlakileng. Jwalo ka mofani ea ka sehloohong oa ethylene glycol Chaena, re fana ka likhetho tse tenyetsehang tsa ho tlisa thepa—ho kenyeletsoa le ho romella thepa ka bongata, li-tote tsa IBC, le meropa ea tšepe ea 220kg—ho netefatsa hore thepa e tlisoa ka nako e loketseng libakeng tse ling lefatšeng ka bophara.
3. Theko ea Ethylene Glycol e Phalisang Haholo
Re sebelisa moruo o moholo ho ntlafatsa litšenyehelo, re fana ka lihlahisoa tsa ethylene glycol tse leka-lekanyang boleng bo holimo le litheko tse hlōlisanang. Maano a rona a ho beha litheko ka mokhoa o hlakileng le mehlala ea tšebelisano-'moho ea nako e telele li thusa bareki ho fokotsa litšenyehelo tsa theko le ho ntlafatsa tlholisano ea bona 'marakeng.
Ho Finyella Lefatše: Molekane oa Hao oa Lefatše ea Tšepahalang oa MEG
Shandong Aojin Chemical e thehile marang-rang a matla a thekiso lefatšeng ka bophara, e romela kantle ho naha Monoethylene Glycol (MEG) linaheng le libakeng tse fetang 30 ho pholletsa le Asia Boroa-bochabela, Bochabela bo Hare, Europe le Amerika. Ka kutloisiso e tebileng ea litlhoko tsa 'maraka oa libaka le litlhoko tsa taolo, re fana ka lihlahisoa le lits'ebeletso tse ikhethileng tse fihlelang maemo a lehae.
