    IZIMPAHLA ZAMAKHEMIkhali

    I-Propylene glycol ngokwesayensi ibizwa ngokuthi “1,2-propanediol”, futhi inefomula yamakhemikhali engu-CH3CHOHCH2OH kanye nesisindo samangqamuzana esingu-76.10.Kukhona i-athomu ye-chiral carbon ku-molecule.I-racemate yayo iyi-hygroscopic viscous liquid futhi inezinongo kancane.Inamandla adonsela phansi athize angu-1.036 (25/4 °C), indawo yokuqanda engu-59 °C, kanye nephuzu elibilayo elingu-188.2 °C, ngokulandelana kwawo 83.2 °C (1,333 Pa).Ixubene namanzi, i-acetone, i-ethyl acetate ne-chloroform, futhi iyancibilika ku-ether.Iyancibilika emafutheni amaningi abalulekile, kodwa ayihlangani ne-petroleum ether namafutha kapharafini.Iyazinza ekushiseni nasekukhanyeni, futhi izinzile emazingeni okushisa aphansi.I-L-isomer yayo inephuzu elibilayo lika-187 kuya ku-189 °C kanye nokujikeleza okuqondile okukhethekile [α] kwe-D20-15.0 °.Ingafakwa i-oxidized emazingeni okushisa aphezulu ku-propionaldehyde, i-lactic acid, i-pyruvic acid ne-acetic acid.

    I-Propylene glycol iyi-diol enemvelo evamile yotshwala.Ingasabela nge-inorganic kanye ne-organic acid ukuze ikhiqize i-mono-noma i-di-esters.Ihlangana ne-propylene oxide ukukhiqiza i-ether, ne-hydrogen halide ukukhiqiza i-halohydrin, kanye ne-acetaldehyde ukukhiqiza i-methyl dioxolane.

    I-Propylene glycol isetshenziselwa izinhlelo zokusebenza ezifanayo njengamanye ama-glycol.
    I-Propylene glycol iyimpahla eluhlaza ebalulekile ye-polyester engagcwalisiwe, i-epoxy resin, ne-polyurethane resin.Inani elisetshenziswa kule ndawo libalelwa ku-45% wengqikithi yokusetshenziswa kwe-propylene glycol.I-polyester enjalo ye-unsaturated isetshenziswa kakhulu kumapulasitiki aqinisiwe kanye nezingubo ezingaphezulu.I-Propylene glycol inhle kakhulu ku-viscosity kanye ne-hygroscopicity futhi ayinabo ubuthi, futhi ngaleyo ndlela isetshenziswa kabanzi njenge-hygroscopic agent, antifreeze, lubricant and solvents embonini yokudla, eyekhemisi nezimonyo.Embonini yokudla, i-propylene glycol isabela nge-fatty acid ukunikeza i-propylene ester yama-fatty acids, futhi isetshenziswa kakhulu njenge-emulsifier yokudla;I-Propylene glycol iyi-solvent enhle yama-flavorings nama-pigments.I-Propylene glycol ivame ukusetshenziswa njengezincibilikisi, izinto ezithambisayo nezisizayo, njll. embonini yezemithi ekwenzeni izinhlobo ezahlukene zamafutha kanye nama-salves.I-Propylene glycol iphinde isetshenziswe njengesixazululi nesithambisi sezimonyo njengoba inokunyibilika okuhle okuhambisanayo nezinongo ezahlukahlukene.I-Propylene glycol iphinde isetshenziswe njengama-ejenti okuthambisa ugwayi, ama-antifungal agents, okokugcoba kwemishini yokucubungula ukudla kanye nezincibilikisi zokufaka inki yokumaka ukudla.Isixazululo esinamanzi se-propylene glycol iyi-ejenti elwa nokuqandisa esebenzayo.

    UTHENGA KANJANI KITHI

    I-Chemwin ingahlinzeka ngenqwaba yama-hydrocarbon amaningi nezincibilikisi zamakhemikhali kumakhasimende ezimboni.Ngaphambi kwalokho, sicela ufunde ulwazi olulandelayo oluyisisekelo mayelana nokwenza ibhizinisi nathi: 

    1. Ezokuphepha

    Ukuphepha kuyinto ehamba phambili yethu.Ngaphezu kokunikeza amakhasimende ulwazi mayelana nokusetshenziswa okuphephile nokunobungani kwemvelo kwemikhiqizo yethu, siphinde sizibophezele ekuqinisekiseni ukuthi ubungozi bokuphepha kwabasebenzi nosonkontileka buncishiswa bube buncane obunengqondo nobunokwenzeka.Ngakho-ke, sidinga ukuthi ikhasimende liqinisekise ukuthi izindinganiso ezifanele zokuphepha zokuthulula nokugcina impahla ziyahlangatshezwa ngaphambi kokulethwa kwethu (sicela ubheke isithasiselo se-HSSE emigomeni nemibandela yokuthengisa ngezansi).Ochwepheshe bethu be-HSSE banganikeza isiqondiso kulawa mazinga.

    2. Indlela yokulethwa

    Amakhasimende anga-oda futhi alethe imikhiqizo evela ku-chemwin, noma angathola imikhiqizo evela embonini yethu yokukhiqiza.Izindlela zokuthutha ezitholakalayo zifaka phakathi iloli, ujantshi noma ezokuthutha ezinezinhlobo eziningi (kuyasebenza izimo ezihlukene).

    Endabeni yezidingo zekhasimende, singacacisa izidingo zezikebhe noma amathangi futhi sisebenzise amazinga akhethekile okuphepha/wokubuyekeza kanye nezimfuneko.

    3. Inani elincane le-oda

    Uma uthenga imikhiqizo kuwebhusayithi yethu, inani elincane le-oda amathani angama-30.

    4.Inkokhelo

    Indlela yokukhokha ejwayelekile idonswa ngokuqondile zingakapheli izinsuku ezingu-30 ukusuka ku-invoyisi.

    5. Amadokhumenti okulethwa

    Amadokhumenti alandelayo anikezwa ngokudiliva ngakunye:

    · I-Bill of Lading, i-CMR Waybill noma enye incwadi yezokuthutha efanele

    · Isitifiketi Sokuhlaziya noma Ukuvumelana (uma sidingeka)

    · Imibhalo ehlobene ne-HSSE ngokuhambisana nemithethonqubo

    · Imibhalo yeCustoms ngokuhambisana nemithethonqubo (uma kudingeka)
