Ubume beempawu

I-DB 75 bubushushu bolwelo kunye nenkqubo yokuqina yokukhanya eyenzelwe i-polyurethanes

Isicelo

I-DB 75 isetyenziswa kwi-polyurethanes efana ne-Reaction Injection Molding (RIM) polyurethane kunye ne-thermoplastic polyurethane (TPU). Umdibaniso usenokusetyenziswa kwi-sealant kunye ne-adhesive applications, kwi-polyurethane yokwambathisa kwi-tarpaulin kunye nomgangatho kunye nakwi-synthetic yesikhumba.

Iimpawu/izibonelelo

I-DB 75 ithintela ukuthotywa, ukukhanya kunye nemozulu ebangela ukuthotywa
yeemveliso ze-polyurethane ezifana neentsimbi zesihlangu, izixhobo kunye neepaneli zomnyango, amavili okuqhuba, i-window encapsulations, intloko kunye nezandla.
I-DB 75 inokongezwa ngokulula kwiinkqubo ezinevumba elimnandi okanye i-aliphatic polyurethane yokubumba i-thermoplastic, amagwebu adityanisiweyo angama-semi-rigid, i-in-mold skinning, ukusetyenziswa kwe-dope. Ingasetyenziswa ngezinto zendalo kunye ne-pigmented. I-DB 75 ifanelekile ngokukodwa ukulungiselela ukuncamathisela kombala okukhanya okuzinzileyo kwezi nkqubo zikhankanywe ngasentla.
Izibonelelo ezongezelelweyo:
kulula ukupompa, ulwelo olugalelwayo luvumela ukuphathwa simahla kothuli, idosi ezenzekelayo kunye nokunciphisa ixesha lokuxuba
yonke iphakheji yolwelo; akukho sedimentation yezongezo kwisigaba se-polyol nakwiqondo lokushisa eliphantsi
ukuxhathisa kwi-exudation / crystallization kwiinkqubo ezininzi ze-PUR

Iifom zemveliso Ulwelo olucacileyo, olutyheli kancinci

Izikhokelo zokusetyenziswa

Amanqanaba okusetyenziswa kwe-DB 75 aphakathi kwe-0.2 % kunye ne-1.5 %, kuxhomekeke kwi-substrate kunye neemfuno zokusebenza kwesicelo sokugqibela:
Amagwebu adibeneyo amacandelo amabini asebenzayo 0.6 % - 1.5 %
Izinto zokuncamathelisa 0.5 % - 1.0 %
Izitywini 0.2 % - 0.5 %
Idatha yokusebenza ebanzi ye-DB 75 iyafumaneka kwizicelo ezininzi.
