Dzina la malonda:Diethylene glycol
Mtundu wa Molecular:C4H10O3
CAS No:111-46-6
Kapangidwe kazinthu zama cell:
Diethylene glycol ndi madzi omveka bwino opanda mtundu, opanda fungo komanso okhazikika.Komanso ndi viscous pang'ono, noncorrosive ndi nonvolatile.Chifukwa cha gulu lake la ether ndi mowa, diethylene glycol imawonetsa zinthu zomwe zimakhala ndi ma alcohols oyambilira komanso ma ether.Kuwira kwake ndikokwera kwambiri kuposa ethylene glycol, ndipo zosungunulira zake ndi zazikulu.Diethylene glycol imasakanikirana ndi madzi, ethers, aliphatic alcohols otsika, aldehydes ndi ketones ndipo imasungunuka pang'ono mu benzene, carbon tetrachloride, monobenzene, orthodichloronebenzene ndi toluene.Amasungunula utoto wambiri, utomoni, mafuta, nitrocellulose ndi zinthu zambiri zachilengedwe.Chifukwa cha mphamvu zake zosungunulira, kusinthasintha kwake komanso kusinthasintha kwa madzi, amagwiritsidwa ntchito popanga mafuta opangira nsalu, mafuta odulira, sopo wotsukira, inki zosindikizira, inki zoyika nthunzi, ndi madontho amitengo yamatabwa.M'makampani opanga nsalu diethylene glycol amagwiritsidwa ntchito ngati chothandizira paubweya, rayon, ndi thonje.Monga chosungunulira cha utoto chimapanga chothandizira chofunikira pakupaka utoto ndi kusindikiza.Kuchuluka kwa hygroscopicity ya diethylene glycol kumapangitsa kuti ikhale yofewa yofewa ya fodya, mapepala, masiponji opangira, zomatira ndi casein.Diethylene glycol ndiwothandiza makamaka pakutha kwa gasi.Kusakaniza kwa diethylene glycol ndi monoethanolamine kudzachotsa chinyezi, hydrogen sulfide ndi carbon dioxide kuchokera ku gasi.
Mu antifreeze njira kwa sprinkler kachitidwe, zisindikizo madzi kwa akasinja gasi, etc. (madzi ndi 40% diethylene glycol amaundana pa -18 °; ndi 50% pa -28 °);monga mafuta ndi kumaliza ntchito ya ubweya, wopotoka, thonje, rayon, ndi silika;monga zosungunulira za utoto wa vat;mu corks, zomatira, gelatin, casein, ndi phala kuti zisamawume.
Diethylene glycol ndi madzi opanda mtundu, opanda fungo, omveka bwino.Ndi miscible ndi madzi mu chiŵerengero chilichonse.Ili ndi ntchito zambiri zamakampani.Ndi chigawo chimodzi cha antifreeze, brake fluids, zodzoladzola, inki, ndi zowumitsa, ndipo amagwiritsidwa ntchito ngati pulasitiki.
Diethylene glycol (DEG) ndi chosungunulira chomwe chimagwiritsidwa ntchito kwambiri pazamalonda ambiri.Amagwiritsidwa ntchito ngati dehydrating wothandizira pokonza gasi;monga mafuta ndi kumaliza ntchito nsalu;zomwe zili mumadzimadzi am'mabuleki, zothira mafuta, zopangira antifreeze, zochotsa pazithunzi ndi njira zopangira chifunga;chosungunulira chosindikizira inki ndi utoto wa nsalu;ndipo amagwiritsidwa ntchito ngati wapakatikati popanga ma resin, triethylene glycol, surfactants, ndi diethylene glycol esters ndi ethers.
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)
