Kugadzirisa hunhu

DB 75 sisitimu yekudzivirira kupisa kwemvura uye chiedza yakagadzirirwa polyurethanes

Kushandiswa

DB 75 inoshandiswa mu polyurethanes dzakadai seReaction Injection Molding (RIM) polyurethane uye thermoplastic polyurethane (TPU). Musanganiswa uyu unogona kushandiswawo mukuisa sealant uye namatidziro, mu polyurethane coating pa tarpaulin ne flooring pamwe chete nedehwe rekugadzira.

Zvinhu/mabhenefiti

DB 75 inodzivirira kuora kunokonzerwa nekugadzirwa, chiedza uye mamiriro ekunze
zvigadzirwa zvepolyurethane zvakaita sezvitsigiro zveshangu, mapaneru emidziyo nemasuo, mavhiri ekufambisa, mahwindo akavharirwa, nzvimbo dzekuzororera nedzekusimudza maoko.
DB 75 inogona kuwedzerwa nyore nyore kune aromatic kana aliphatic polyurethane systems ye thermoplastic moldings, semi-rigid integral foams, in-mold skinning, uye dope applications. Inogona kushandiswa nezvinhu zvechisikigo uye zvakapendwa. DB 75 inonyanya kukodzera kugadzirira mavara akapfava akasimba esystem dzataurwa pamusoro apa.
Mamwe mabhenefiti:
mvura iri nyore kupomba, inodururwa ichibvumira kubata isina guruva, inoongororwa otomatiki uye inopfupikisa nguva yekusanganisa
zvese zvine mvura; hapana kusvibiswa kwezvinowedzera mu polyol phase kunyangwe patembiricha yakaderera
inodzivirira kupiswa kwemvura muPUR system dzakawanda

Mafomu echigadzirwa

Mitemo yekushandisa

Mashandisirwo eDB 75 ari pakati pe0.2% ne1.5%, zvichienderana nezvinodiwa nesubstrate uye mashandiro ekushandisa kwekupedzisira:
Mafuro ekubatanidza ane zvikamu zviviri zvinopindura 0.6 % – 1.5 %
Zvinonamira 0.5% - 1.0%
Zvivharo 0.2 % – 0.5 %
Ruzivo rwakakura rwekushanda kweDB 75 runowanikwa kune akawanda maapplication.
