Plasticizers i Fauga Fa'apipi'i
Pipiʻi o lo'o fa'aaogaina e pulea ai le fa'agasologa o le fa'agasologa o fa'alavalava fa'avae i luga ole fa'amagoina fa'aletino mea e fai ai ata. O le faʻatulagaina lelei o ata tifaga e manaʻomia ina ia mafai ai ona faʻamalieina manaʻoga i mea faʻapipiʻi faʻapitoa e pei o foliga mamago ata, faʻapipiʻi substrate, elasticity, faʻatasi ma le maualuga maualuga o le maaa i le taimi e tasi
Plasticizers galue e ala i le faʻaitiitia o le vevela o le faʻavaeina o ata ma faʻafefeteina le ufiufi; palasitika e galue e ala i le faʻapipiʻiina o latou lava i le va o filifili o polymers, vaʻavaʻavaʻavaʻa (faʻateleina le "volume saoloto"), ma faʻapena ona faʻaitiitia ai le vevela suiga tioata mo le polymer ma faʻamalieina.
O molelaula i polymeric film fai mea, e pei o le nitrocellulose (NC), e masani ona faʻaalia le maualalo o filifili feʻaveaʻi, faʻamatalaina e ala i fegalegaleaiga mole mole malosi (faʻamatalaina e van der Waals forces) o filifili polymer. O le matafaioi a le plasticizer o le faʻaitiitia poʻo le taofia atoa o le faʻavaeina o ia fusi faʻatasi. I le tulaga o polymers synthetic e mafai ona ausia lenei mea e ala i le tuʻufaʻatasia o vaega elasticizing poʻo monomers e faʻalavelave faʻalavelaveina fegalegaleaiga mole; ua lauiloa lenei faagasologa o suiga vailaau o le "plasticization totonu". Mo natural oloa poʻo polymers faigata o le le lelei o le gaosiga, o le filifiliga o le faʻaogaina i fafo plasticizers i le faʻapipiʻiina o le ufiufi
Plasticizers fegalegaleai faaletino ma le polymer binder mole, e aunoa ma se kemikolo tali ma fausia se faiga tutusa. O le fegalegaleai e faʻavae i luga o le fausaga faʻapitoa o le plasticizer, e masani ona aofia ai polar ma non-polar moieties, ma iʻu ai i lalo ole vevela tioata (Tg). Ina ia faʻamautinoa le maualuga o le lelei, e tatau ona mafai e le plasticizer ona tuʻi i totonu o le resini i tulaga e faia ai ata.
O mea fa'apipi'i masani o mea mole mole mamafa, pei ole phthalate esters. Ae ui i lea, e le'i leva atu nei oloa e maua fua ole phthalate e sili ona fa'agata ona o le fa'aogaina ole phthalate esters e fa'atapula'aina ona o popolega i le saogalemu o oloa.
