Ituaiga o Polimers Inisinia Biodegradable
Ole fanua ole biodegradable engineering polymers ua vave ona fa'aleleia, ma mea fou o lo'o fa'aauau pea ona atia'e.O nisi nei o ituaiga iloga:
- Polylactic Acid (PLA):E maua mai i puna'oa fa'afouina e pei ole masoa o sana, ole PLA ose tasi o polymers e mafai ona fa'aleagaina.E ofoina atu le malosi lelei, manino, ma le biocompatibility, faʻapena lelei mo afifiina, ie, ma masini faʻafomaʻi.
- Polyhydroxyalkanoates (PHAs):O nei polymers fa'alenatura e gaosia e meaola ninii e fa'aalia ai le lelei tele o le biodegradability ma le agava'a.O lo'o su'esu'eina PHA mo fa'aoga ile afifiina, vaega ta'avale, ma ata fa'ato'aga.
- Polymers fa'avae i le cellulose:E maua mai i le pulupulu laupapa poʻo isi mea e maua ai le cellulose, o nei polymers e ofoina atu le malosi lelei, biodegradability, ma e mafai ona faʻaogaina mo faʻaoga faʻapitoa.O loʻo suʻesuʻeina mo le faʻaaogaina i mea faʻapipiʻi, mea faʻapipiʻi, ma ie.
- Polymers fa'avae masoa:Fa'afefiloi ole masoa ma isi polymers po'o mea fa'apipi'i fa'aolaola e mafai ona fa'atupu ai mea e mafai ona fa'aleagaina ma lelei le malosi ma uiga fa'agaioiga.O talosaga e aofia ai le afifiina, oloa lafoai, ma mea faufale.
Fa'amanuiaga o le Fa'aaogaina o Polymers Biodegradable Engineering
O le fa'aogaina o polymers fa'ainisinia biodegradable e maua ai le tele o le si'osi'omaga ma le tamaoaiga:
- Fa'aitiitia otaota lapisi:O mea e mafai ona pala e pala pe a uma ona faʻaaogaina, faʻaitiitia le avega i luga o lapisi ma faʻalauiloaina se faiga e sili atu ona gafataulimaina o otaota.
- Punaoa Fa'afouina:O le tele o polymers biodegradable e maua mai i punaoa faʻafouina e pei o fualaʻau poʻo microorganisms, faʻaitiitia ai le faʻalagolago i suauʻu.
