Imiterere y'ibiranga

DB 75 ni sisitemu yo gushimangira ubushyuhe n'urumuri yagenewe polyurethane

Porogaramu

DB 75 ikoreshwa muri polyurethane nka Reaction Injection Molding (RIM) polyurethane na thermoplastic polyurethane (TPU). Uruvange rushobora kandi gukoreshwa mu gushyiramo ibifunga no gufunga, mu gusiga polyurethane ku mabati no hasi ndetse no mu ruhu rw’ubukorano.

Ibiranga/inyungu

DB 75 irinda kwangirika kw'ibikomoka ku gutunganya, urumuri n'ikirere
ibikoresho bya polyurethane nk'inkweto zo mu gitereko, ibikoresho n'inzugi, amapine y'imodoka, ibifunga by'amadirishya, aho gufatira imitwe n'amaboko.
DB 75 ishobora kongerwamo byoroshye muri sisitemu za polyurethane zihumura neza cyangwa za aliphatic kugira ngo zikoreshwe mu buryo bwa thermoplastic moldings, semi-rigid integral foams, in-mold skinning, dope applications. Ishobora gukoreshwa hamwe n'ibikoresho bisanzwe n'ibifite irangi. DB 75 ikwiriye cyane cyane mu gutegura amabara yoroheje ahoraho kuri sisitemu zavuzwe haruguru.
Izindi nyungu:
byoroshye kuvoma, amazi ashobora gusukwa atuma umuntu atabona ivumbi, agakoresha ingano yikora kandi agatuma igihe cyo kuvanga kigabanuka.
ipaki yose y'amazi; nta gushonga kw'inyongera mu cyiciro cya polyol nubwo haba hari ubushyuhe buke
irwanya exudation/crystallization muri sisitemu nyinshi za PUR

Amabwiriza yo gukoresha

Ingano z'ikoreshwa rya DB 75 ziri hagati ya 0.2% na 1.5%, bitewe n'imiterere n'ibisabwa mu ikoreshwa rya nyuma:
Ifuro ry'ibice bibiri rikora neza 0.6% – 1.5%
Ibikoresho byo gufunga 0.5% - 1.0%
Ibifunga 0.2 % – 0.5 %
Amakuru menshi y'imikorere ya DB 75 araboneka kuri porogaramu nyinshi.
