E fa'afefea ona fai le resini o le phenol formaldehyde?

Bakelite o le phenolic resin.Phenolic resin (PF) o se ituaiga o oloa gaosi oloa palasitika.O mea mataʻutia o le gaosiga o le resini phenolic e masani lava o le phenol ma le aldehyde, ma o le phenol ma le formaldehyde e masani ona faʻaaogaina.E polymerized e ala i le condensation tali i lalo o le catalysis o acid, faavae ma isi catalysts.E lua ituaiga o gaosiga o alamanuia: faiga mago ma faiga susu.

I lalo o le gaioiga a faʻamaʻi eseese, phenol ma aldehyde e mafai ona maua ai ituaiga e lua o resini phenolic: tasi o le thermoplastic phenolic resin, o le isi o le thermosetting phenolic resin.O le mea muamua e mafai ona faʻamalolo i totonu o le poloka poloka e ala i le faʻaopopoina o le vailaʻau faʻamalolo ma le faʻamafanafanaina, ae o le mea mulimuli e mafai ona faʻamalolo i totonu o le fausaga poloka e ala i le faʻamafanafanaina e aunoa ma le faʻaopoopoina o le vailaʻau faʻamalolo.

Thermoplastic phenolic resin ma thermosetting phenolic resin e mafai ona faʻaaogaina e ala i fesoʻotaʻiga fefaʻatauaʻiga na faia e ala ile faʻamalolo.O le faʻamalologa o le faʻaauauina o foliga polycondensation ma le faʻavaeina o oloa foliga.O lenei faiga e ese mai le liusuavai ma le faʻamaloloina o thermoplastics lautele.O faiga fa'aletino ma kemisi e le mafai ona toe fa'afo'isia.

Phenolic resin e mafai ona tui i se auala tutusa ma thermoplastic.PF mo tui tuie manaʻomia le suavai lelei, e mafai ona faʻapipiʻiina i lalo o le mamafa o le tui, maualuga le vevela, faʻamaʻaʻaina vave, faʻalelei lelei o vaega palasitika, faʻafefe faigofie, ma leai se faʻaleagaina.Ae ui i lea, o le tui tui e iai foʻi ona faʻaletonu.Mo se faʻataʻitaʻiga, o le faʻafefeteina e faʻatapulaʻaina e le ituaiga o faʻatumu, o lea e le talafeagai ai le faʻaogaina o faʻapipiʻi e fai ai vaega palasitika.Ole tele ole faitoto'a ma alavai e le mafai ona toe fa'aaogaina pe a uma ona fofo, ma e mafai ona lafoai.

I se upu, thermoplastic phenolic resin e mafai ona gaosia e masini masani tui tui, ae o le faagasologa o tulaga e matua pulea.Thermosetting phenolic resin e tatau ona gaosia e se masini faʻapipiʻi tui faʻapitoa mo resini phenolic, ma faʻaaogaina foi e le limu se fausaga mamanu faʻapitoa.

E fa'aaogaina lautele imea tau eletise, lagolago, tuu moli,atigi masini sanuisi, ma isi;Ae ui i lea, o lona faʻaogaina maaleale ma faʻalavelave faʻalavelave faʻalavelave e ono faʻatapulaʻaina lona atinaʻe.Faatasi ai ma le tulaʻi mai o isi palasitika, e le faigofie ona vaʻai i le taimi nei oloa bakelite.E ui lava e manaʻomia le faʻavevelaina o mea faʻapipiʻi mo le faʻapipiʻiina, o le taimi e faʻaogaina ai e umi atu nai lo palasitika masani, ma o loʻo faʻaofuofu e sili atu le tele, lea e manaʻomia ai le maualuga o manaʻoga mo le uamea, ae ona o lona tulaga lelei i le tau o meafaitino, e o lo'o avea pea ma sui mo le tele o vaega palasitika.
