Propylene glycol ka saense e bitsoa "1,2-propanediol", 'me e na le foromo ea lik'hemik'hale ea CH3CHOHCH2OH le boima ba molek'hule ea 76.10. Ho na le athomo ea chiral carbon ka molek'hule. Racemate ea eona ke mokelikeli oa hygroscopic viscous mme o na le linoko tse nyane. E na le matla a khoheli a khethehileng a 1.036 (25/4 °C), ntlha ea leqhoa ea-59 °C, le ntlha e belang ea 188.2 °C, ka ho latellana 83.2 °C (1,333 Pa). E kopane le metsi, acetone, ethyl acetate le chloroform, 'me e qhibiliha ka har'a ether. E qhibiliha ka har'a oli e ngata ea bohlokoa, empa ha e kopane le petroleum ether le oli ea parafine. E batla e tsitsitse ho mocheso le khanya, 'me e tsitsitse haholoanyane mochesong o tlaase. L-isomer ea eona e na le ntlha e belang ea 187 ho ea ho 189 ° C le ho potoloha ho itseng ha optical [α] ea D20-15.0 °. E ka oxidized ka mocheso o phahameng ho propionaldehyde, lactic acid, pyruvic acid le acetic acid.
Propylene glycol ke diol e nang le mofuta o akaretsang oa joala. E ka sebetsana le inorganic le organic acid ho hlahisa mono-kapa di-esters. E kopana le propylene oxide ho hlahisa ether, ka hydrogen halide ho hlahisa halohydrin, le acetaldehyde ho hlahisa methyl dioxolane.
Propylene glycol e sebelisoa bakeng sa lits'ebetso tse ts'oanang le li-glycol tse ling.
Propylene glycol ke thepa e tala ea bohlokoa bakeng sa polyester e sa tsitsang, resin ea epoxy, le resin ea polyurethane. Chelete ea tšebeliso sebakeng sena e etsa hoo e ka bang 45% ea kakaretso ea tšebeliso ea propylene glycol. Polyester e joalo e sa tsitsang e sebelisoa haholo bakeng sa lipolasetiki tse matlafalitsoeng le ho roala holim'a metsi. Propylene glycol e ntle haholo ka viscosity le hygroscopicity mme ha e na chefo, ka hona e sebelisoa haholo joalo ka hygroscopic agent, antifreeze, lubricant le solvents indastering ea lijo, ea meriana le ea litlolo. Ka indasteri ea lijo, propylene glycol e sebetsana le mafura a mafura ho fana ka propylene ester ea mafura a acids, 'me e sebelisoa haholo-holo e le emulsifier ea lijo; Propylene glycol ke motsoako o motle bakeng sa tatso le li-pigments. Propylene glycol e atisa ho sebelisoa e le li-solvents, li-softeners le li-excipients, joalo-joalo indastering ea meriana bakeng sa ho etsa mefuta e sa tšoaneng ea mafura le litlolo. Propylene glycol e boetse e sebelisoa e le solvent le softener bakeng sa litlolo kaha e na le ho qhibiliha ho hotle hammoho le linoko tse fapaneng. Propylene glycol e boetse e sebelisoa e le lisebelisoa tse kolobisang koae, li-antifungal agents, lisebelisoa tsa ho lokisa lijo le lihlapolli bakeng sa enke e tšoaeang lijo. Tharollo e nang le metsi ea propylene glycol ke ntho e sebetsang e thibelang leqhoa.
Chemwin e ka fana ka mefuta e mengata ea li-hydrocarbon tse ngata le li-solvents tsa lik'hemik'hale bakeng sa bareki ba indasteri.Pele ho moo, ka kopo bala lintlha tse latelang mabapi le ho etsa khoebo le rona:
1. Tshireletso
Tšireletseho ke eona ntho e tlang pele bophelong ba rona. Ntle le ho fa bareki tlhahisoleseling mabapi le ts'ebeliso e sireletsehileng le e baballang tikoloho ea lihlahisoa tsa rona, re boetse re ikemiselitse ho netefatsa hore likotsi tsa polokeho ea basebetsi le borakonteraka li fokotsoa ho ba bonyane bo utloahalang le bo ka khonehang. Ka hona, re hloka hore moreki a etse bonnete ba hore litekanyetso tse nepahetseng tsa ho laolla le ho boloka polokeho li fihlelleha pele ho tlisoa ha rona (ka kopo sheba sehlomathiso sa HSSE ho latela maemo le maemo a kakaretso a thekiso a ka tlase). Litsebi tsa rona tsa HSSE li ka fana ka tataiso mabapi le litekanyetso tsena.
2. Mokhoa oa ho fana
Bareki ba ka odara le ho fana ka lihlahisoa ho tsoa ho chemwin, kapa ba ka fumana lihlahisoa ho tsoa femeng ea rona ea tlhahiso. Mekhoa e teng ea lipalangoang e kenyelletsa lipalangoang tsa literaka, terene kapa mefuta e mengata (maemo a arohaneng a sebetsa).
Tabeng ea litlhoko tsa bareki, re ka hlakisa litlhoko tsa likepe kapa litanka mme ra sebelisa litekanyetso tse khethehileng tsa polokeho / tlhahlobo le litlhoko.
3. Palo e fokolang ea taelo
Haeba u reka lihlahisoa sebakeng sa rona sa marang-rang, palo e tlase ea odara ke lithane tse 30.
4.Tefo
Mokhoa o tloaelehileng oa ho lefa ke ho fokotsa ka kotloloho matsatsing a 30 ho tsoa ho invoice.
5. Litokomane tsa thomello
Litokomane tse latelang li fanoe ka thomello ka 'ngoe:
· Bill of Lading, CMR Waybill kapa tokomane e 'ngoe e amehang ea lipalangoang
· Setifikeiti sa Tlhahlobo kapa Tumellano (haeba ho hlokahala)
· Litokomane tse amanang le HSSE tumellanong le melaoana
· Litokomane tsa meetlo ho latela melaoana (haeba ho hlokahala)
