    Meatotino oloa & Vaega

    RFE polyisocyanate ose feso'ota'iga sili ona aoga mo fa'apipi'i fa'avae i luga ole polyurethane, pa'u fa'anatura ma le pa'u Synthesis. RFE polyisocyanate e aoga foi mo le faʻaleleia atili o le pipii o mea faʻavae paʻu. E mafai ona faʻaaogaina e fai ma crosslinker nai lo le Bayer's Desmodur RFE.

    Fa'aoga

    E tatau ona fa'aoga mea fa'apipi'i e lua-vaega ma le vaitaimi talafeagai pe a uma ona tu'u i totonu o le RFE.
    O le umi o le vaitaimi talafeagai e le gata e fesoʻotaʻi ma le polymer anotusi o le pipii, ae faʻapea foʻi ma isi vaega talafeagai (pei o resin, Antioxygen, plasticizer, solvent, etc.
    A latalata i le taimi talafeagai, e masani lava o ni nai itula poʻo le tasi le aso faigaluega, o le faʻapipiʻi e sili atu ona faigata ona faʻaogaina, ma vave ona oso aʻe le viscosity.
    Mulimuli ane, e avea ma jelly e le mafai ona toe fa'afo'isia. 100 fa'apipi'i lelei, Hydroxyl polyurethane (Fa'amatalaga Polyurethane mo le 20%), RFE faia 4-7. Chloroprene pa'u ( Rubber account mo le 20%), RFE faia 4-7.

    afifiina

    afifi: 0.75kg / fagu, atoa 20 fagu i le tasi pusa pusa, 180kg / paelo, PO e tusa ai ma manaoga o tagata faatau.
    afifi-RE-11

    Teuina

    - Teuina i totonu o le pusa Covestro faʻamaufaʻailoga muamua.
    - Fautuaina le vevela vevela: 10 - 30 °C.
    - Puipui mai le susu, vevela ma mea mai fafo.
    Fa'amatalaga lautele: I le taimi o felauaiga ma le teuina i le vevela maualalo,e mafai ona fausia ni faaputuga tioata.
    O nei mea e toe solo i le vevela o le potu. O leoloa e matua maaleale i le susu ma tali atu i le vai e fausia ai carbondioxide ma le urea e le mafai ona solu.
    O le mea lea e tatau ai ona teu lelei pusafa'amaufa'ailogaina. Le fa'aofiina o le vai i so'o se ituaiga (koneteina susu, anhydroussolvents, ea susu) e tatau ona puipuia e pei o le faia o le carbono le dioxide e ono fa'atupu ai se fa'atupu mata'utia fa'ateleina o le mamafa i totonu o koneteina.
    O le fa'aalia i le ea ma/po'o le malamalama e fa'ateteleina ai le liu lanu ae leai se a'afiagao meatotino fa'agaioiga lautele.
