Fa'aaogāga o Mea

PnB e masani ona faʻaaogaina e fai ma sui faʻamamā mo mea faʻaleagaina mamafa. E mafai ona faʻamavaeina le suauʻu faʻapipiʻi ma gaʻo lelei ma faʻaoga lelei mo le fua o fale ma fale gaosi oloa. Ole vaega ole soluble ile vai, ole PnB e mafai ona solubilize le tele ole solvent ma le talosaga e pei ona taua i lalo:

① e pei o le fale ma fale gaosi oloa, aveese le gaʻo ma vali, soʻo faʻapipiʻi ma solvent o uʻamea ma faʻamaʻa luga;

② e avea ma so'o fa'apipi'i lelei ma so'oso'o fa'aluulu vai fa'aitiitia;

③ e avea ma sooupu coagulating aoga o vai-faavae vali emulsion;

④ avea ma solvent malosi o vali e faavae i solvent;

⑤ e pei o vailaʻau vavalo mo ester, solvent ma plasticizer gaosiga.

DPnB
Talosaga i le faʻapipiʻiina:i le avea ai ma se tasi o ausilali sili e fausia ai ata o vali vai, e mafai ona faʻaaogaina le DPnB e fai ma faʻamaʻi o le resini acrylic, phenylethylene acrylic resin ma le polyvinyl acetate e tuʻuina atu ai le faʻatinoga sili ona lelei e vali ata.
Fa'aoga ile fa'amama: e fa'atatau i mea fa'amama fa'apitoa mo i latou e mana'omia le maualalo o le saosaoa, e pei o le fa'amama ma le fola. I le avea ai ma sui so'otaga lelei mo le lubricating ga'o ma ga'o, e mafai ona fa'aoga le DPnB e fai ma vali vali ma aveese ga'o manu.
Isi talosaga:E mafai fo'i ona fa'aoga le DPnB i mea tau fa'ato'aga, mea teuteu, vaitusi fa'aeletonika ma ie.
