Polypropylene Palasitika(PP)
* O le Polypropylene ose fa'ameamea tioata semikristi. E maualuga le a'afiaga, malosi fa'ainisinia, ma tete'e atu i so'o so'o eseese ma fa'ama'i fa'ameamea.
* Fa'agata fa'ama'i sili ona lelei Mea'ai saogalemu togi avanoa.
* Fa'apitoa PP palasitika oloa po'o vaega
Polypropylene, fa'apu'upu'u e pei o le PP, o se polymer faia mai propylene e ala i se polymerization tali. O se mea pa'epa'e, waxy ma foliga manino ma mama. Fuainumera kemisi (C3H6)n, density 0.89 ~ 0.91g/cm3, mu, liusuavai tulaga o 164 ~ 170 ° C, faamaluluina i le 155 ° C po o lea, le faaaogaina o le tele o le vevela o le -30 ~ 140 ° C.
E teteʻe i le pala e ala i le acid, alkali, masima vai ma le tele o ituaiga solvents organic i lalo ifo o le 80 ℃, ma e mafai ona pala i lalo o le maualuga o le vevela ma le faʻamaʻiina. E faʻaaogaina i le tele o faʻaoga, e aofia ai le faʻapipiʻiina o tagata faʻatau, vaega palasitika mo fale gaosi oloa ma ie.
O le a se mea e mafai ona e faia i le PP Plastic?
O le Polypropylene o le palasitika sili ona mama i tulaga o le mamafa. O lona foliga mai e leai ni lanu ma translucent granules, ma o se palasitika meaʻai, e masani ona faʻaaogaina i meaʻai afifi, e pei o pusa Styrofoam, ipu palasitika PP, ma isi. O le Polypropylene e mafai ona vaevaeina i ni vaega autu se lima e tusa ai ma ana faʻaoga autu: PP tui faʻapipiʻi, ata PP, fiber PP, ata tifaga PP, ma paipa PP.

Polypropylene (PP) Uiga
Tete'e i vaila'au: E le fa'afefete fa'ama'i fa'ama'i ma vai fa'atasi ma le PP, ma avea ai ma koneteina lelei mo ia vai (fa'ata'ita'iga o mea fa'amamā, mea fesoasoani muamua, ma isi).
Elasticity ma faigata: O le PP e faʻamalosi i totonu o se vaega o le faʻafefeteina ma e oʻo i le palasitika palasitika i le amataga o le faʻaogaina o le faʻagasologa e aunoa ma le malepelepe, o lea e masani ona manatu o se mea "faigata".
Tete'e vaivai: PP tumau lona foliga pe a uma le tele o mimilo ma punou. O lenei meatotino e taua tele mo le faia o faʻamau faʻaoga.
Insulation: O mea PP e maualuga le malosi o le eletise ma o se mea faʻapipiʻi.
Transmittance: E mafai ona faia i lanu manino, ae masani ona faia i lanu opaque masani ma se tikeri faapitoa o transmittance. Afai e mana'omia le felauaiga maualuga, e tatau ona filifilia le acrylic po'o le PC.
E fa'afefea ona fai mea PP?
E pei o isi palasitika, o le Polypropylene (PP) e amata o se "vaega" (vaega mama) mai le faʻamama o suauʻu hydrocarbon ma tuʻufaʻatasia ma isi faʻamalosi e maua ai palasitika e ala i polymerization poʻo polycondensation reactions.

Polypropylene (PP) – Fa'agasologa o le gaosiga:
O le pauta na maua e iu lava ina ave i le pauta silos ona liua lea i pellets e aofia ai se vaega atoa
mea fa'aopoopo fa'asalalau lelei.
Polypropylene (PP) palasitika toe faʻaaogaina ma puipuiga o le siosiomaga
Pe a toe faʻaaogaina le polypropylene, e faʻaitiitia ai le faʻaaogaina o punaoa faʻapitoa e pei o le suauu ma le kasa propane. E tusa ma le 8% o le suauʻu o le lalolagi (e tusa ma le 400 miliona tone) o loʻo faʻaaogaina i auala masani o gaosiga o palasitika, lea e 4% o loʻo faʻaaogaina e fai ma "feedstock" ma le isi 4% o loʻo faʻaaogaina i le gaosiga. Afai o palasitika e gaosia mai i palasitika toe faʻaaogaina, o le a faʻaititia foi le malosi i le 88%. O le toe fa'aaogaina o palasitika polypropylene e fa'alelei le si'osi'omaga!
