    CHEMICAL PROPERTIES

    Propylene glycol yog lub npe hu ua "1,2-propanediol", thiab muaj cov tshuaj formula ntawm CH3CHOHCH2OH thiab molecular hnyav ntawm 76.10.Muaj chiral carbon atom nyob rau hauv lub molecule.Nws racemate yog hygroscopic viscous kua thiab yog me ntsis ntsim.Nws muaj lub ntiajteb txawj nqus ntawm 1.036 (25/4 ° C), qhov chaw khov ntawm -59 ° C, thiab qhov kub ntawm 188.2 ° C, raws li 83.2 ° C (1,333 Pa).Nws yog miscible nrog dej, acetone, ethyl acetate thiab chloroform, thiab yog soluble hauv ether.Nws yog soluble nyob rau hauv ntau yam tseem ceeb roj, tab sis tsis yog miscible nrog roj av ether thiab paraffin roj.Nws yog qhov ruaj khov rau cua sov thiab lub teeb, thiab ruaj khov dua ntawm qhov kub thiab txias.Nws cov L-isomer muaj qhov kub ntawm 187 txog 189 ° C thiab ib qho kev sib hloov kho qhov muag [α] ntawm D20-15.0 °.Nws tuaj yeem oxidized ntawm qhov kub thiab txias rau propionaldehyde, lactic acid, pyruvic acid thiab acetic acid.

    Propylene glycol yog diol uas muaj cov dej cawv.Nws tuaj yeem cuam tshuam nrog inorganic thiab organic acids los tsim mono-los yog di-esters.Nws reacts nrog propylene oxide los tsim ether, nrog hydrogen halide los tsim halohydrin, thiab nrog acetaldehyde los tsim methyl dioxolane.

    Propylene glycol yog siv rau cov ntawv zoo sib xws li lwm cov glycols.
    Propylene glycol yog ib qho tseem ceeb raw khoom rau unsaturated polyester, epoxy resin, thiab polyurethane resin.Kev siv nyiaj hauv cheeb tsam no suav txog li 45% ntawm tag nrho kev noj propylene glycol.Xws li polyester unsaturated yog siv dav rau cov yas reinforced thiab nto txheej.Propylene glycol yog zoo heev nyob rau hauv viscosity thiab hygroscopicity thiab yog non-toxic, thiab yog li yog dav siv raws li hygroscopic tus neeg saib xyuas, antifreeze, lubricants thiab hnyav nyob rau hauv cov zaub mov, tshuaj thiab tshuaj pleev ib ce kev lag luam.Hauv kev lag luam khoom noj khoom haus, propylene glycol reacts nrog fatty acid muab propylene ester ntawm fatty acids, thiab yog siv los ua zaub mov emulsifier;Propylene glycol yog ib qho hnyav hnyav rau flavorings thiab pigments.Propylene glycol feem ntau yog siv los ua cov kuab tshuaj, softeners thiab excipients, thiab lwm yam.Propylene glycol kuj tseem siv los ua cov kuab tshuaj thiab cov softener rau cov tshuaj pleev ib ce vim nws muaj kev sib nrig sib solubility nrog ntau yam txuj lom.Propylene glycol kuj yog siv los ua luam yeeb moisturizing agents, antifungal agents, food processing equipment lubricants and solvents for food marking number.Aqueous tov ntawm propylene glycol yog ib tug zoo anti-freeze tus neeg saib xyuas.

    YUAV UA LI CAS LOS NTAWM US

    Chemwin tuaj yeem muab ntau hom hydrocarbons thiab cov kuab tshuaj tshuaj lom neeg rau cov neeg siv khoom.Ua ntej ntawd, thov nyeem cov lus qhia hauv qab no txog kev ua lag luam nrog peb: 

    1. Kev ruaj ntseg

    Kev nyab xeeb yog peb qhov tseem ceeb tshaj plaws.Ntxiv nrog rau kev muab cov neeg siv khoom paub txog kev nyab xeeb thiab ib puag ncig tus phooj ywg siv ntawm peb cov khoom, peb kuj tau cog lus los xyuas kom meej tias qhov kev pheej hmoo ntawm kev nyab xeeb ntawm cov neeg ua haujlwm thiab cov neeg ua haujlwm raug txo qis rau qhov tsim nyog thiab ua tau tsawg kawg nkaus.Yog li ntawd, peb xav kom tus neeg siv khoom kom ntseeg tau tias qhov tsim nyog tshem tawm thiab khaws cov qauv kev nyab xeeb tau ua tiav ua ntej peb xa khoom (thov xa mus rau HSSE appendix nyob rau hauv cov nqe lus dav dav thiab kev muag khoom hauv qab no).Peb cov kws tshaj lij HSSE tuaj yeem muab kev taw qhia txog cov qauv no.

    2. Txoj kev xa khoom

    Cov neeg siv khoom tuaj yeem xaj thiab xa khoom los ntawm chemwin, lossis lawv tuaj yeem tau txais cov khoom los ntawm peb cov chaw tsim khoom.Cov hom kev thauj mus los muaj xws li tsheb thauj mus los, tsheb ciav hlau lossis kev thauj mus los ntau yam (xws li kev sib cais).

    Nyob rau hauv cov ntaub ntawv ntawm cov neeg yuav tsum tau, peb muaj peev xwm qhia kom meej cov kev cai ntawm barges los yog tankers thiab siv tshwj xeeb kev nyab xeeb / tshuaj xyuas cov qauv thiab cov kev cai.

    3. Yam tsawg kawg nkaus kom muaj nuj nqis

    Yog tias koj yuav khoom los ntawm peb lub vev xaib, qhov kev txiav txim yam tsawg kawg nkaus yog 30 tons.

    4. Kev them nyiaj

    Txoj kev them nyiaj tus qauv yog txiav tawm ncaj qha hauv 30 hnub txij li daim ntawv xa nyiaj.

    5. Cov ntaub ntawv xa tuaj

    Cov ntaub ntawv hauv qab no tau muab nrog rau txhua qhov kev xa khoom:

    · Bill of Lading, CMR Waybill lossis lwm yam ntaub ntawv thauj mus los

    · Certificate of Analysis los yog Conformity (yog xav tau)

    · Cov ntaub ntawv hais txog HSSE raws li txoj cai

    · Cov ntaub ntawv kev lis kev cai raws li txoj cai (yog tias xav tau)
