DB 75 ndi madzi kutentha ndi kuwala stabilizer dongosolo lakonzedwa polyurethanes

Kugwiritsa ntchito

DB 75 imagwiritsidwa ntchito mu polyurethanes monga Reaction Injection Molding (RIM) polyurethane ndi thermoplastic polyurethane (TPU).Kuphatikizikako kungagwiritsidwenso ntchito posindikiza ndi zomatira, mu zokutira za polyurethane pa tarpaulin ndi pansi komanso pachikopa chopanga.

Mbali/ubwino

DB 75 imalepheretsa kuwonongeka, kuwala ndi nyengo zomwe zimayambitsa kuwonongeka
zopangidwa ndi polyurethane monga nsapato za nsapato, zida ndi mapanelo a zitseko, mawilo owongolera, ma encapsulations a zenera, kupumula mutu ndi mkono.
DB 75 imatha kuwonjezeredwa mosavuta pamakina onunkhira kapena aliphatic polyurethane opangira ma thermoplastic, thovu lokhazikika lokhazikika, kukopa mu nkhungu, kugwiritsa ntchito dope.Itha kugwiritsidwa ntchito ndi zinthu zachilengedwe komanso zamtundu.DB 75 ndi yoyenera kwambiri pokonzekera phala lamtundu wosakhazikika pamakina omwe tawatchulawa.
Zowonjezera zabwino:
zosavuta kupopa, madzi kuthira kulola fumbi kugwira ntchito, yodzichitira mlingo ndi kufupikitsa kusakaniza nthawi
phukusi lonse lamadzi;palibe sedimentation wa zina mu polyol gawo ngakhale pa kutentha otsika
kugonjetsedwa ndi exudation / crystallization mu machitidwe ambiri a PUR

Mankhwala amadzimadzi Omveka bwino, achikasu pang'ono

Malangizo ogwiritsira ntchito

Miyezo yogwiritsira ntchito DB 75 imakhala pakati pa 0.2 % ndi 1.5 %, kutengera gawo laling'ono ndi zofunikira pakugwiritsa ntchito komaliza:
Zomwe zimagwiritsidwa ntchito pazinthu ziwiri zowonjezera 0.6% - 1.5%
Zomatira 0.5% - 1.0%
Zisindikizo 0.2% - 0.5%
Zambiri zogwirira ntchito za DB 75 zilipo pamapulogalamu ambiri.
