    IIPROPATI ZEKHEMICAL

    Ipropylene glycol ibizwa ngokwesayensi ngokuthi "1,2-propanediol", kwaye ine-chemical formula ye-CH3CHOHCH2OH kunye ne-molecular weight ye-76.10.Kukho iathom yekhabhoni yechiral kwimolekyuli.Iracemate yayo ilulwelo lwe-hygroscopic viscous kwaye inonongo kancinane.Inobunzima obuthile be-1.036 (25/4 °C), indawo yokukhenkceza ye-59 °C, kunye neqondo lokubilisa le-188.2 °C, ngokulandelanayo 83.2 °C (1,333 Pa).Ixubene namanzi, i-acetone, i-ethyl acetate kunye ne-chloroform, kwaye iyanyibilika kwi-ether.Iyanyibilika kwii-oyile ezininzi ezibalulekileyo, kodwa ayixutywanga ne-petroleum ether kunye neoyile yeparafini.Izinzile xa ithelekiswa nobushushu kunye nokukhanya, kwaye izinzile kumaqondo aphantsi.I-L-isomer yayo inendawo yokubilisa ye-187 ukuya kwi-189 ° C kunye nokujikeleza okuthe ngqo kwe-optical [α] ye-D20-15.0 °.Inokuthi ifakwe kwi-oxidized kumaqondo aphezulu kwipropionaldehyde, i-lactic acid, i-pyruvic acid kunye ne-acetic acid.

    Ipropylene glycol yidiol enobume obuqhelekileyo botywala.Inokusabela nge-inorganic kunye ne-organic acids ukuvelisa i-mono-okanye i-di-esters.Idibana ne-propylene oxide ukwenza i-ether, kunye ne-hydrogen halide ukwenza i-halohydrin, kunye ne-acetaldehyde ukwenza i-methyl dioxolane.

    Ipropylene glycol isetyenziselwa izicelo ezifanayo njengezinye ii-glycols.
    Ipropylene glycol yimathiriyeli ekrwada ebalulekileyo yepolyester engaxutywanga, i-epoxy resin, kunye ne-polyurethane resin.Isixa sokusetyenziswa kule ndawo malunga ne-45% yokusetyenziswa ngokupheleleyo kwepropylene glycol.I-polyester enjalo engasetyenziswanga isetyenziswe ngokubanzi kwiiplastiki eziqinisiweyo kunye neengubo zangaphandle.Ipropylene glycol igqwesileyo kwi-viscosity kunye ne-hygroscopicity kwaye ayinayo ityhefu, kwaye ngoko isetyenziswa ngokubanzi njenge-agent ye-hygroscopic, i-antifreeze, i-lubricants kunye ne-solvents kumashishini okutya, amayeza kunye ne-cosmetic.Kwishishini lokutya, i-propylene glycol iphendula nge-fatty acid ukunika i-propylene ester ye-fatty acids, kwaye isetyenziswa kakhulu njenge-emulsifier yokutya;Ipropylene glycol sisinyibilikisi esilungileyo sencasa kunye neepigments.Ipropylene glycol isetyenziswa ngokuqhelekileyo njengama-solvents, i-softeners kunye nabancedisi, njl.Ipropylene glycol ikwasetyenziswa njengesinyibilikisi kunye nesithambisi sezithambiso kuba inonyibiliko olufanelekileyo oludibanisayo kunye neziqholo ezahlukeneyo.Ipropylene glycol ikwasetyenziswa njengeejenti zokuthambisa icuba, ii-antifungal agents, izixhobo zokulungisa ukutya kunye nezinyibilikisi zokumakisha ukutya.Isisombululo esinamanzi sepropylene glycol sisixhobo esisebenzayo sokuchasa umkhenkce.

    INDLELA YOKUTHENGA KUTHI

    I-Chemwin inokubonelela ngoluhlu olubanzi lwee-hydrocarbons ezininzi kunye nezinyibilikisi zeekhemikhali kubathengi bamashishini.Ngaphambi koko, nceda ufunde olu lwazi lulandelayo olusisiseko malunga nokwenza ishishini nathi: 

    1. Ukhuseleko

    Ukhuseleko yeyona nto iphambili kuthi.Ukongeza ekunikeni abathengi ngolwazi malunga nokusetyenziswa ngokukhuselekileyo nokuhambelana nokusingqongileyo kweemveliso zethu, sikwazimisele ekuqinisekiseni ukuba imingcipheko yokhuseleko lwabasebenzi kunye neekontraka ziyathotywa ukuya kutsho kubuncinane obufanelekileyo nobunokwenzeka.Ngoko ke, sifuna ukuba umthengi aqinisekise ukuba imigangatho efanelekileyo yokukhutshwa kunye nokugcinwa kwemigangatho yokhuseleko idibene ngaphambi kokunikezelwa kwethu (nceda ubhekisele kwisihlomelo se-HSSE kwimimiselo jikelele kunye neemeko zokuthengisa ngezantsi).Iingcali zethu zeHSSE zinokubonelela ngesikhokelo kule migangatho.

    2. Indlela yokuhambisa

    Abathengi banokuodola kwaye bahambise iimveliso kwi-chemwin, okanye banokufumana iimveliso kwisityalo sethu sokuvelisa.Iindlela ezikhoyo zothutho ziquka iilori, uloliwe okanye uthutho lweendlela ezininzi (kuyasebenza iimeko ezahlukileyo).

    Kwimeko yeemfuno zabathengi, sinokucacisa iimfuno zeenqanawa okanye iitanki kwaye sisebenzise imigangatho ekhethekileyo yokhuseleko / ukuhlaziya kunye neemfuno.

    3. Ubuncinci bobungakanani bomyalelo

    Ukuba uthenga iimveliso kwiwebhusayithi yethu, ubungakanani obuncinci bomyalelo ziitoni ezingama-30.

    4.Intlawulo

    Indlela yokuhlawula eqhelekileyo itsalwa ngokuthe ngqo kwiintsuku ezingama-30 kwi-invoyisi.

    5. Amaxwebhu okuhanjiswa

    La maxwebhu alandelayo anikwe ngokuziswa ngakunye:

    · Ibhili yokuLading, i-CMR Waybill okanye olunye uxwebhu olufanelekileyo lwezothutho

    · Isatifikethi sokuHlalutya okanye ukuThobela (ukuba siyafuneka)

    · Amaxwebhu anxulumene neHSSE ngokuhambelana nemigaqo

    · Amaxwebhu ezinto eziqhelekileyo ngokuhambelana nemigaqo (ukuba kuyafuneka)
