O le Phthalic anhydride o le fa'aputu fa'aola ma le fua fa'atatau C6H4(CO)2O.O le anhydride o le phthalic acid.O lenei malo e leai ni lanu o se vailaʻau faʻapisinisi taua, aemaise lava mo le gaosiga tele o mea faʻapipiʻi mo palasitika
.Phthalic anhydride o se vailaʻau taua tele i totonu o pisinisi palasitika lea e maua mai ai le tele o esters phthalate o loʻo galue e pei o mea faʻapipiʻi i resini gaosia.Phthalic anhydride lava ia e faʻaaogaina e fai ma monomer mo resini gaosia e pei o glyptal, resins alkyd, ma resins polyester.
Phthalic anhydride o loʻo faʻaaogaina foi e fai ma mea muamua o le anthraquinone, phthalein, rhodamine, phthalocyanine, fluorescein, ma xanthene dyes.
Phthalic anhydride o loʻo faʻaaogaina i le tuʻufaʻatasia o amine muamua, o le faʻatoʻaga fungicide phaltan, ma le thalidomide.O isi gaioiga fa'atasi ma le phthalic anhydride e maua mai ai le phenolphthalein, benzoic acid, phthalylsulfathiazole (o se vaila'au fa'ama'i fa'ama'i), ma le acid orthophthalic.
O le tuufaatasiga o se vailaʻau maualuga-tonnage ma e masani ona faʻaaogaina i le tele o faʻalapotopotoga faʻalapotopotoga faʻapisinisi.
O le Phthalic anhydride e faʻaaogaina i le gaosiga o polyesters e le faʻamaʻaʻaina ma e fai ma vailaʻau faʻamalolo mo resini epoxy.A faʻaaogaina e fai ma pigmenti, e mafai ona nafa ma le faʻalogoina o tagata faigaluega sima.
O le Phthalic Anhydride o se mea fa'aola ma le anhydride o le phthalic acid (P384480).O le Phthalic Anhydride o se vailaʻau faʻapisinisi taua e masani ona faʻaaogaina i le gaosiga tele o mea faʻapipiʻi f poʻo palasitika.O su'esu'ega talu ai nei na iloilo ai fo'i le Phthalic Anhydride e mafai ona fa'ama'i fa'ama'i.
gaosiga o phthaleins, phthalates, benzoic acid, synthetic indigo, resins (glyptal).
Intermediate mo Plastizers, vali, vali ma Pigments, Polyester Resins.
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)
