Ukuchazwa kwabalinganiswa

I-DB 75 yinkqubo yolwelo yokuqinisa ubushushu nokukhanya eyenzelwe ii-polyurethanes

Isicelo

I-DB 75 isetyenziswa kwi-polyurethanes ezifana ne-Reaction Injection Molding (RIM) polyurethane kunye ne-thermoplastic polyurethane (TPU). Lo mxube ungasetyenziswa nakwizicelo ze-sealant kunye ne-adhesive, kwi-polyurethane coating kwi-tarpaulin nakwi-floor kunye nakwi-synthetic leather.

Iimpawu/iingenelo

I-DB 75 ithintela ukuwohloka okubangelwa kukucubungula, ukukhanya kunye nemozulu
iimveliso ze-polyurethane ezifana nezihlangu, iiphaneli zezixhobo kunye neengcango, amavili okuqhuba, ii-encapsulations zeefestile, iindawo zokuphumla entloko nakwiingalo.
I-DB 75 ingongezwa ngokulula kwiinkqubo ze-polyurethane ezinuka kamnandi okanye ezi-aliphatic kwiimoldings ze-thermoplastic, ii-foams eziqinileyo, i-in-mold skinning, kunye ne-dope applications. Ingasetyenziswa ngezinto zendalo nezinombala. I-DB 75 ifanelekile ngokukodwa ekulungiseleleni ii-paste zombala ezizinzileyo ezikhanyayo kwiinkqubo ezikhankanyiweyo apha ngasentla.
Ezinye iingenelo:
kulula ukupompa, ulwelo olunokugalelwa oluvumela ukuphathwa okungenathuli, idosi ezenzekelayo kunye nokunciphisa ixesha lokuxuba
yonke iphakheji yolwelo; akukho sedimentation yezithako kwisigaba sepolyol nokuba kumaqondo obushushu aphantsi
ayimelani ne-exudation/crystallization kwiinkqubo ezininzi ze-PUR

Iifom zemveliso Ulwelo olucacileyo, olumthubi kancinci

Izikhokelo zokusetyenziswa

Amanqanaba okusetyenziswa kwe-DB 75 aphakathi kwe-0.2% kunye ne-1.5%, kuxhomekeke kwisiseko kunye neemfuno zokusebenza kwesicelo sokugqibela:
Iifoam ezidibeneyo ezisebenza ngezinto ezimbini ezisebenzayo 0.6 % – 1.5 %
Izincamathelisi 0.5% – 1.0%
Izitywini 0.2 % – 0.5 %
Idatha yokusebenza ebanzi ye-DB 75 iyafumaneka kwiizicelo ezininzi.
