Folasaga

Styrene, o se vai e leai ni lanu ma se manogi manogi fa'apitoa. O lo'o taua i lalo se fa'amatalaga i meatotino, fa'aoga, metotia sauniuni ma fa'amatalaga saogalemu o le styrene:

 

Tulaga lelei:

1. mama mama.

2. E fe'avea'i i le vevela o le potu ma e maualalo le moli ma le pa.

3. E fa'afefiloi ma so'o so'o eseese ma ose mea fa'aola taua tele.

 

Fa'aaogā:

1. Styrene o se vailaʻau mataʻutia taua, e masani ona faʻaaogaina i le tuʻufaʻatasia o se numera tele o palasitika, paʻu gaosia ma filo.

2. E mafai ona faʻaogaina le Styrene e fai ai mea faʻapipiʻi e pei o le polystyrene (PS), polystyrene rubber (SBR) ma le acrylonitrile-styrene copolymer.

3. E mafai foʻi ona faʻaaogaina e gaosia ai vailaʻau faʻapitoa e pei o meaʻai ma suauʻu lubricating.

 

Metotia:

1. E mafai ona maua le Styrene e ala i le dehydrogenation e ala i le faʻamafanafanaina ma le faʻamalosiina o molelaʻau ethylene.

2. E mafai fo'i ona maua le Styrene ma le hydrogen e ala ile fa'avevela ma ta'e le ethylbenzene.

 

Fa'amatalaga Saogalemu:

1. Styrene e mu ma e tatau ona puipuia mai le mumu ma le maualuga o le vevela.

2. O le fa'afeso'ota'i ma le pa'u e ono fa'aitaitagofie ai ma fa'a'ai ai, ma e tatau ona faia ni puipuiga talafeagai.

3. O se taimi umi po'o le tele o le fa'aalia e ono i ai ni a'afiaga fa'alesoifua maloloina, e aofia ai le fa'aleagaina o le fatugalemu, ate, ma fatuga'o.

4. Faʻalogo lelei i le siosiomaga faʻafefe pe a faʻaaoga, ma aloese mai le inhalation poʻo le inuina.

5. O le lafoaia o otaota e tatau ona tausisia tulafono ma tulafono faatonutonu talafeagai, ma e le tatau ona lafoai pe lafoai i le loto.
