Fa'amatalaga Oloa

Faailoga o oloa

Fa'amatalaga:O le Stearyl methacrylate o se vailaʻau taua tele, o lona homopolymer poʻo le copolymer o maleic anhydride ma le styrene, e mafai ona faʻaleleia atili le sua o oloa suauʻu i le maualalo o le vevela.Stearyl acrylate polymers o lo'o i ai se fausaga selu, lea fofo e tele uiga.O lo'o fa'aaogaina lautele e avea o se mea fa'afefete fa'afefe ma fa'afeso'ota'i i le faiga fa'amaloloina fa'avevela.Fa'aaoga fo'i e pei o palasitika, pa'u modifiers, coating leveling agents, coatings and paints release agents, suau'u sasaa vaega depressants, binders eseese.

 

Talosaga:

1. Fa'aaogaina i le fa'afefeteina o le togi sasaa, sui fa'auma ie, fesoasoani pa'u, palasitika, suau'u suau'u resini.

2. E mafai ona faʻaaogaina e fai ai mea faʻapipiʻi, faʻapipiʻi, pepa faʻapipiʻi pepa, faʻapipiʻi suauʻu lubricating, aemaise lava mo le faʻapipiʻiina o pulupulu ie, e fesoasoani ai i le faʻapipiʻiina o ata tifaga, faʻaleleia le malosi o le pulupulu, ma faʻateleina le lamolemole luga.

 

afifi:170kg mamafa mama po'o mana'oga e pei o Tagata Fa'atau.

 

Felauaiga ma le teuina:

Aloese mai timuga susulu ma le maualuga o le vevela i felauaiga;

Teu oloa i totonu o le malulu, paolo ma faʻafefe, faʻamama mamao mai le afi;

12 masina mai le aso na tu'uina atu i le maualuga o le vevela o le teuina o le 25℃.
