O le Diethylene glycol o se vai e leai ni lanu, e leai se manogi ma mautu. E la'ititi fo'i, e le pala ma e le fe'avea'i. Ona o le vaega o le ether ma le ava malosi, o le diethylene glycol o lo'o fa'aalia ai uiga fa'a-kemikolo o lo'o fa'aalia uma ai le 'ava malosi ma le eter. O lona tulaga fa'apuna e matua maualuga atu nai lo le ethylene glycol, ma o lona solvent e sili atu. O le Diethylene glycol e fa'afefiloi ma vai, eter, 'ava malosi aliphatic pito i lalo, aldehydes ma ketones ma e solu se vaega i le benzene, carbon tetrachloride, monobenzene, orthodichlorobenzene ma toluene. E fa'amavae le tele o vali, resini, suau'u, nitrocellulose ma le tele o mea fa'aola. Ona o lona malosi solvent, volatility maualalo ma hygroscopicity, e faʻaaogaina i lubricants ie, suauʻu tipi, fasimoli mamago, vaitusi lolomi, vaitusi seti ausa, ma stains laupapa nongrain. I totonu o fale gaosi oloa e faʻaaogaina le diethylene glycol e avea o se sui faʻapipiʻi mo fulufulu mamoe, rayon, ma cotton. I le avea ai o se solvent mo vali e faia ai se fesoasoani taua i le valiina ma le lolomiina. O le maualuga o le hygroscopicity o le diethylene glycol ua avea ai ma so'o fa'amalulu lelei mo tapaa, pepa, omomi gaosia, kelu ma casein. O le Diethylene glycol e sili ona aoga i le fa'amama o le kesi masani. O le fa'afefiloi o le diethylene glycol ma le monoethanolamine o le a aveesea ai le susu, hydrogen sulfide ma le carbon dioxide mai le kasa masani.
I totonu o vaifofo faʻamaʻi faʻamaʻi mo mea faʻapipiʻi, faʻamaufaʻailoga vai mo tane kesi, ma isi. e pei o le lubricating ma le faʻamaeʻaina o fulufulu mamoe, leaga, cotton, rayon, ma siliki; e fai ma solvent mo vali vai; i totonu o pupuni tu'ufa'atasiga, kelu, gelatin, casein, ma pa'u e taofia ai le mago.
Diethylene glycol o se vai e leai se lanu, leai se manogi, manino. E fefiloi ma le vai i soo se fua faatatau. E tele lona fa'aoga tau alamanuia. O se vaega o le antisaisa, vai taofi, mea teuteu, vaitusi, ma mea faʻamago, ma e faʻaaogaina e fai ma palasitika.
O le Diethylene glycol (DEG) o se mea e masani ona faʻaaogaina ma mea e faʻaaogaina i le tele o oloa faʻapisinisi. E faʻaaogaina e avea o se mea e faʻamalo ai le suavai mo le gaosiga o kasa masani; e fai ma lubricating ma fa'amae'a sui mo 'ie; o se mea fa'avae i su'a taofi, lubricants, fa'apipi'i fa'aantisaisa, pepa fa'apalapala ma vaifofo fa'afu; o se solu mo vaitusi lolomi ma vali ie; ma o loʻo faʻaaogaina e fai ma mea faʻavauvau i le gaosiga o nisi resins, triethylene glycol, surfactants, ma diethylene glycol esters ma ethers.
E mafai e Chemwin ona tuʻuina atu le tele o vailaʻau hydrocarbons ma vailaʻau vailaʻau mo tagata faʻatau pisinisi.Aʻo leʻi faia lena mea, faʻamolemole faitau faʻamatalaga autu nei e uiga i le faia o pisinisi ma matou:
1. Puipuiga
O le saogalemu o la tatou faamuamua sili. I le faaopoopo atu i le tuʻuina atu i tagata faʻatau faʻamatalaga e uiga i le saogalemu ma le faʻaogaina o le siosiomaga oa matou oloa, matou te tuuto atu foi i le faʻamautinoaina o le saogalemu o lamatiaga o tagata faigaluega ma konekarate e faʻaitiitia i se tulaga talafeagai ma mafai. O le mea lea, matou te manaʻomia le tagata faʻatau e faʻamautinoa ua ausia tulaga talafeagai o le laʻuina ma le teuina o le saogalemu aʻo leʻi tuʻuina atu (faʻamolemole vaʻai i le faʻaopoopoga HSSE i aiaiga lautele ma aiaiga o faʻatau i lalo). O matou tagata tomai faapitoa i le HSSE e mafai ona tuʻuina atu taʻiala i nei tulaga.
2. Tuuina atu auala
E mafai e tagata fa'atau oloa ona fa'atonu ma tu'uina atu oloa mai le chemwin, pe mafai fo'i ona latou maua oloa mai le matou fale gaosi oloa. O auala o felauaiga o lo'o avanoa e aofia ai loli, nofoaafi po'o felauaiga tele (tulaga eseese e fa'atatau).
I le tulaga o manaoga o tagata faatau, e mafai ona matou faʻamaonia manaʻoga o vaʻa poʻo vaʻa ma faʻaoga tulaga faʻapitoa mo le saogalemu / iloiloga ma manaʻoga.
3. Fa'atonuga maualalo
Afai e te faʻatau oloa mai la matou upega tafaʻilagi, o le aofaʻi aupito maualalo ole oka ole 30 tone.
4. Totogi
Ole auala masani ole totogi ole toesega tuusao ile 30 aso mai le pili.
5. Tuuina atu pepa
O pepa nei o lo'o tu'uina atu i fa'asalalauga ta'itasi:
· Bill of Lading, CMR Waybill po'o isi pepa felauaiga talafeagai
· Tusi Faamaonia o Suʻesuʻega poʻo Faʻatatau (pe a manaʻomia)
· Fa'amaumauga e feso'ota'i i le HSSE e tusa ai ma tulafono fa'atonutonu
· Fa'amaumauga a le Ofisa o Tiute e tusa ai ma tulafono fa'atonutonu (pe a mana'omia)
