FAQ
Asɛmmisa: Dɛn na ɛma DHP yi gyina hɔ pintinn?
A: Nea ɛka ho ne trace stabilizers (sɛ nhwɛso no, BHT) a esiw polymerization a ɛba ara kwa ano, titiriw wɔ acidic anaa ɔhyew tebea horow mu.
Asɛmmisa: So stabilizer no besiw THP ether a wɔhyehyɛ no kwan?
A: Dabi, wɔnom stabilizer no anaasɛ ɛnhaw no wɔ acidic tebea horow a wɔtaa de di dwuma de bɔ nsa ho ban no mu.
Asɛmmisa: So wobetumi de eyi adi dwuma wɔ nnuru a wɔde yɛ nnuru mu?
A: Yiw. Wɔkamfo kyerɛ sɛ wobɛhwɛ sɛ stabilizer no ne wo application pɔtee no hyia, titiriw wɔ mmeae a wɔahyɛ ho mmara.
