Kun jumɛnw de bɛ PVC plastiki jɛman na?

Plastiki jɛman bɛ tali kɛ cakɛda min bɛ i n’a fɔ polimɛri molekiyɔmu cakɛda ka kari funteni caman na, oksidan sigida la, walima ultraviolet, infrarouge, ani microorganismes (fɛnɲɛnamafɛnw) ka baara kɔrɔ, o min bɛ radical free detachment (banakisɛfagalanw bɔli) daminɛ.

Plastikiw ka jɛnɛya jɛlen bɛ ninnu de la kɛrɛnkɛrɛnnenya la:

1. ultraviolet radiation .

Tile bɛ yeelen min Bɔ ka Taa kɛnɛma fiɲɛ-yɔrɔ la, o ye spektrum ye min bɛ Taa ‘ɲɛ ni 0,7-3000nm ye, o la 300-400Nm ultraviolet radiation ye polimɛri tiɲɛni sababuba ye. Wa fotonw fanga min bɛ 290-400nm ultraviolet kɔnɔ o ye 300-419KJ/E ye, o ka ca ni ɲɔgɔndan fanga ye kemikɛli jɛɲɔgɔnya suguya dɔw la polimɛriw kɔnɔ.

2. Funteni sabatili fɛɛrɛ .

Funteni sabatili fura suguya wɛrɛw bɛ nɔ wɛrɛw bila PVC ka yeelen sabatili la.

BA/CD ni organotin karɔkisilati faralenw (i n’a fɔ anhidridi ɔriganotini stabilisateurs maleiques éster) bɛ se ka UV sabatili hakɛ dɔ di PVC cogoya ma minnu bɛ kɛ kɛnɛma, ka sɔrɔ fɛnɲɛnamafagalan minnu bɛ sɔrɔ fɛnɲɛnamafagalan na (i n’a fɔ sulfure alcool biological tin stabilizers) olu bɛ se ka sabatili danma di. Di-kɔgɔ-plɔmu sabatili yeelen sabatili ka bon ka tɛmɛ satalan sabatilen sabatili kan.

3. Antioxydant system ka fanga .

Sisan, PVC profile dilanbagaw bɛ baara kɛ ni sabatililan minnu ye, olu ye stabilisateurs composites ye kosɛbɛ. Ka fara fɛnɲɛnamafagalanba kan min bɛ PVC tiɲɛni sabati, u bɛ tulumafɛnw, farikolo tangalanw ani sabatili fɛɛrɛ wɛrɛw fana sɔrɔ.

Antioxydant system bɛ se ka kɛ fenɔli stabilisateurs ani fosphite co-stabilizers ye. Nin furakisɛ ninnu bɛ se ka kɛ nɔgɔw ye minnu ɲɛ ye ɲɛgɛnw ye nɔgɔya la, wa ka fara o kan, u bɛ se ka kulɛri caman bɔ yeelen, oksizɛni ani ji ka baara la.
