Propylene glycol imatchulidwa mwasayansi kuti "1,2-propanediol", ndipo ili ndi mankhwala a CH3CHOHCH2OH ndi molekyulu yolemera 76.10. Pali atomu ya kaboni ya chiral mu molekyulu. Racemate yake ndi hygroscopic viscous madzi ndipo ndi zokometsera pang'ono. Ili ndi mphamvu yokoka yeniyeni ya 1.036 (25/4 °C), malo oundana a-59 °C, ndi malo otentha a 188.2 °C, motsatira 83.2 °C (1,333 Pa). Imasakanikirana ndi madzi, acetone, ethyl acetate ndi chloroform, ndipo imasungunuka mu ether. Amasungunuka m'mafuta ambiri ofunikira, koma samasakanikirana ndi petroleum ether ndi mafuta a parafini. Imakhala yokhazikika pakutentha ndi kuwala, ndipo imakhala yokhazikika pakatentha kwambiri. L-isomer yake imakhala ndi malo otentha a 187 mpaka 189 ° C ndi kusinthasintha kwapadera [α] kwa D20-15.0 °. Itha kukhala oxidized pa kutentha kwambiri kwa propionaldehyde, lactic acid, pyruvic acid ndi acetic acid.
Propylene glycol ndi diol yokhala ndi mowa wambiri. Itha kuchitapo kanthu ndi ma inorganic ndi ma organic acid kuti apange mono-kapena di-esters. Imachita ndi propylene oxide kupanga ether, ndi hydrogen halide kupanga halohydrin, ndi acetaldehyde kupanga methyl dioxolane.
Propylene glycol imagwiritsidwa ntchito ngati ma glycols ena.
Propylene glycol ndi chinthu chofunikira chopangira poliyesitala wosaturated, epoxy resin, ndi utomoni wa polyurethane. Ndalama zomwe zimagwiritsidwa ntchito m'derali zimakhala pafupifupi 45% yazomwe zimagwiritsidwa ntchito pa propylene glycol. Polyester yosakanizidwa yotereyi imagwiritsidwa ntchito kwambiri popanga mapulasitiki olimbikitsidwa ndi zokutira pamwamba. Propylene glycol ndi yabwino kwambiri ku viscosity ndi hygroscopicity ndipo si poizoni, motero imagwiritsidwa ntchito kwambiri ngati hygroscopic agent, antifreeze, lubricants ndi solvents muzakudya, mankhwala ndi zodzikongoletsera. M'makampani azakudya, propylene glycol imakhudzidwa ndi mafuta acid kuti apereke propylene ester yamafuta acids, ndipo amagwiritsidwa ntchito makamaka ngati emulsifier ya chakudya; Propylene glycol ndi yabwino kusungunulira zokometsera ndi inki. Propylene glycol imagwiritsidwa ntchito ngati zosungunulira, zofewa komanso zowonjezera, ndi zina zambiri m'makampani opanga mankhwala popanga mitundu yosiyanasiyana yamafuta ndi ma salves. Propylene glycol imagwiritsidwanso ntchito ngati zosungunulira komanso zofewa zodzikongoletsera chifukwa imakhala yabwino kusungunuka ndi zonunkhira zosiyanasiyana. Propylene glycol imagwiritsidwanso ntchito ngati zonyowetsa fodya, antifungal agents, mafuta opangira chakudya ndi zosungunulira za inki yolembera chakudya. Madzi amadzimadzi a propylene glycol ndi anti-freeze agent.
Chemwin ikhoza kupereka ma hydrocarbon ambiri ambiri ndi zosungunulira zamankhwala kwa makasitomala aku mafakitale.Izi zisanachitike, chonde werengani mfundo zotsatirazi zokhuza kuchita bizinesi nafe:
1. Chitetezo
Chitetezo ndicho chofunikira kwambiri chathu. Kuphatikiza pa kupatsa makasitomala chidziwitso chokhudza kugwiritsa ntchito bwino komanso kusamala zachilengedwe kwa zinthu zathu, tadziperekanso kuwonetsetsa kuti chiwopsezo chachitetezo cha ogwira ntchito ndi makontrakitala chikuchepetsedwa kukhala chocheperako komanso chotheka. Choncho, tikufuna kuti kasitomala awonetsetse kuti miyezo yoyenera yotsitsa ndi kusunga chitetezo ikukwaniritsidwa tisanaperekedwe (chonde onani zowonjezera za HSSE pazogulitsa zomwe zili pansipa). Akatswiri athu a HSSE atha kupereka chitsogozo pamiyezo iyi.
2. Njira yobweretsera
Makasitomala amatha kuyitanitsa ndikutumiza zinthu kuchokera ku chemwin, kapena atha kulandira zinthu kuchokera kumakampani athu opanga. Njira zoyendera zomwe zilipo zikuphatikiza magalimoto, njanji kapena ma multimodal (mikhalidwe yosiyana imagwira ntchito).
Pankhani ya zofuna za makasitomala, titha kufotokoza zofunikira za mabwato kapena akasinja ndikugwiritsa ntchito miyezo yapadera yachitetezo / kuwunika ndi zofunikira.
3. Kuchuluka kwa dongosolo lochepa
Ngati mumagula zinthu patsamba lathu, kuchuluka kwa madongosolo ocheperako ndi matani 30.
4.Kulipira
Njira yolipirira yokhazikika imachotsedwa mwachindunji mkati mwa masiku 30 kuchokera pa invoice.
5. Zolemba zotumizira
Malemba otsatirawa amaperekedwa pakubweretsa kulikonse:
· Bill of Lading, CMR Waybill kapena chikalata china chamayendedwe
· Satifiketi Yowunikira kapena Yogwirizana (ngati pakufunika)
· Zolemba zokhudzana ndi HSSE mogwirizana ndi malamulo
· Zolemba za kasitomu mogwirizana ndi malamulo (ngati pakufunika)
