Kufotokozera makhalidwe:

DB 117 ndi njira yotsika mtengo, yotenthetsera madzi ndi yokhazikika bwino, yokhala ndi zinthu zolimbitsa kuwala ndi zotsutsana ndi ma antioxidants, zomwe zimapangitsa kuti magetsi ambiri a polyurethane akhale olimba kwambiri panthawi yomwe ikugwiritsidwa ntchito.

Katundu Wathupi

Mawonekedwe: Madzi achikasu, okhuthala

Mapulogalamu

DB 117 imagwiritsidwa ntchito mu ma polyurethane monga Reaction Injection Molding, thermoplastic polyurethane synthetic chikopa, cast polyurethanes, ndi zina zotero. Chosakanizachi chingagwiritsidwenso ntchito mu sealant ndi zomatira, mu polyurethane covering pa tarpaulin ndi pansi, mu thovu lopangidwa komanso m'makhungu osakanikirana.

Zinthu/ubwino

DB 117 imaletsa kuwonongeka kwa zinthu za polyurethane zomwe zimapangidwa ndi zinthu monga nsapato, zida ndi zitseko, mawilo owongolera, zophimba mawindo, zopumira mutu ndi manja m'njira yotsika mtengo.
DB 117 ikhoza kuwonjezeredwa mosavuta ku machitidwe a polyurethane onunkhira kapena aliphatic kuti apange mapangidwe a thermoplastic, ma foam okhwima pang'ono, kupukuta khungu mkati mwa mold, kugwiritsa ntchito dope. Itha kugwiritsidwa ntchito ndi zinthu zachilengedwe komanso zopaka utoto. Yoyenera kwambiri pokonzekera ma phala amitundu yopepuka yokhazikika pamachitidwe omwe atchulidwa pamwambapa.
DB 117 ndi madzi osavuta kupompa, otha kuthiridwa omwe amalola kugwiritsa ntchito fumbi, mlingo wokha komanso kuchepetsa nthawi yosakaniza. Amalola kupeza phindu pochepetsa kulemera kapena kuyeza ntchito imodzi. Popeza ndi phukusi lamadzimadzi lokha, palibe kusungunuka kwa zowonjezera mu gawo la polyol komwe kumachitika ngakhale kutentha kochepa.
Kuphatikiza apo, DB 117 yatsimikizira kuti imalimbana ndi exudation/crystallization m'machitidwe ambiri oyesedwa a PUR.

Kagwiritsidwe:

0.2% ndi 5%, zimadalira gawo lapansi ndi zofunikira pakugwira ntchito komaliza.
