Meatotino oloa & Vaega

RFE polyisocyanate ose feso'ota'iga sili ona aoga mo fa'apipi'i e 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.

Ole umi ole 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 vaitaimi talafeagai, e masani lava o ni nai itula poʻo le tasi le aso faigaluega, faʻapipiʻi e sili atu ona faigata ona faʻaogaina, ma vave 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.

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 leo oloa e matua maaleale i le susu ma tali atu i le vai e fai ai le kaponidioxide 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.
