Ukwenziwa kwezinhlamvu

I-DB 75 iwukushisa okuwuketshezi kanye nesistimu yokuqinisa ukukhanya eyenzelwe ama-polyurethanes

Isicelo

I-DB 75 isetshenziswa kuma-polyurethanes afana ne-Reaction Injection Molding (RIM) polyurethane kanye ne-thermoplastic polyurethane (TPU). Le nhlanganisela ingasetshenziswa futhi ekufakweni kophawu nokunamathelayo, ekufakweni kwe-polyurethane kuseyili nephansi kanye nasesikhumbeni sokwenziwa.

Izici/izinzuzo

I-DB 75 ivimbela ukuwohloka okubangelwa ukucubungula, ukukhanya kanye nesimo sezulu
yemikhiqizo ye-polyurethane efana nezicathulo, amapaneli ensimbi nezicabha, amasondo okuqondisa, amafasitela encapsulations, ikhanda nezandla.
I-DB 75 ingengezwa kalula ezinhlelweni ezinuka kamnandi noma ze-aliphatic polyurethane zokubunjwa kwe-thermoplastic, amagwebu ayingxenye eqinile, ukukhunta okungaphakathi kwesikhunta, ukusetshenziswa kwe-dope. Ingasetshenziswa ngezinto zemvelo kanye ne-pigmented. I-DB 75 ifaneleka ngokukhethekile ukulungisa okunamathiselwe kombala okuzinzile kwalezi zinhlelo ezishiwo ngenhla.
Izinzuzo ezengeziwe:
kulula ukupompa, uketshezi oluthelayo oluvumela ukuphatha okungenathuli, umthamo ozenzakalelayo kanye nokunciphisa isikhathi sokuxuba
yonke iphakheji ye-liquid; akukho sedimentation of izithasiselo esigabeni polyol ngisho emazingeni okushisa aphansi
ukumelana ne-exudation/crystallization ezinhlelweni eziningi ze-PUR

Amafomu omkhiqizo Uketshezi olucacile, oluphuzi kancane

Imihlahlandlela yokusetshenziswa

Amazinga okusetshenziswa e-DB 75 ahluka phakathi kuka-0.2 % no-1.5 %, kuye nge-substrate nezidingo zokusebenza zohlelo lokusebenza lokugcina:
Amagwebu abalulekile ezingxenye ezimbili asebenzayo 0.6 % - 1.5 %
Izinamathiselo 0.5 % - 1.0 %
Ama-Sealants 0.2 % - 0.5 %
Idatha yokusebenza ebanzi ye-DB 75 iyatholakala ezinhlelweni eziningi.
