O a uiga o le Polypropylene (PP)?

O nisi o mea sili ona taua o le polypropylene o:
1.Chemical Resistance: O faʻavae faʻafefeteina ma vailaʻau e le faʻafefeteina ma le polypropylene, lea e avea ai ma se filifiliga lelei mo pusa o ia vai, e pei o mea faʻamamā, mea fesoasoani muamua, ma isi mea.
2. Elasticity ma Toughness: Polypropylene o le a galue ma elasticity i luga o se ituaiga o deflection (pei o mea uma), ae o le a oo foi i le palasitika deformation vave i le faagasologa deformation, o lea e masani ona manatu o se mea "faigata". Toughness o se upu inisinia lea e faauigaina o se mea e mafai ona faʻaleagaina (faʻapipiʻi, ae le o le faʻamalosi) e aunoa ma le gau.
3. Fatigue Resistance: O le Polypropylene e tumau pea lona foliga pe a maeʻa le tele o faʻalavelave, punou, ma / poʻo le faʻafefe. O lenei meatotino e sili ona taua mo le faia o faʻamau ola.
4. Insulation: o le polypropylene e maualuga tele le tetee i le eletise ma e aoga tele mo vaega eletise.
5.Transmissivity: E ui lava e mafai ona faʻamalamalamaina le Polypropylene, e masani lava ona gaosia ina ia faʻapitoa i le lanu. E mafai ona fa'aogaina le Polypropylene mo fa'aoga e taua tele ai le fa'aliliuina atu o le malamalama po'o le mea e fa'alelei ai. Afai e manaʻomia le maualuga o le felauaiga ona sili atu lea o palasitika pei o Acrylic poʻo Polycarbonate.
O le Polypropylene o lo'o fa'avasegaina o se mea "thermoplastic" (e fa'afeagai ma le "thermoset") e fa'atatau i le auala e tali atu ai le palasitika i le vevela. E fa'asuavaa mea fa'amama i lo latou tulaga liusuavai (pe tusa ma le 130 tikeri Celsius i le tulaga ole polypropylene).
O se uiga taua tele e uiga i thermoplastics e mafai ona faʻamafanafanaina i lo latou tulaga liusuavai, malulu, ma toe faʻamafanafana e aunoa ma se faʻaleagaina tele. Nai lo le susunuina, thermoplastics pei o le polypropylene liquefy, lea e mafai ai ona faigofie ona tui ma toe faʻaaogaina.
I se fa'afeagai, e na'o le tasi lava le fa'avevela o palasitika thermoset (e masani lava i le taimi o le fa'aogaina o tui). O le fa'avevela muamua e mafua ai ona fa'atutu mea fa'amalo (e tutusa ma le 2-vaega epoxy) e mafua ai se suiga o vaila'au e le mafai ona toe suia. Afai e te taumafai e fa'avevela se palasitika fa'avela i se vevela maualuga mo le taimi lona lua e na'o le mu. Ole uiga lea e fa'aletonu ai meafaitino fa'ameamea mo le toe fa'aaogaina.
