72021E UV-resin yolumikizira zinthu zambiri

Polyurethane Acrylate 72021E: "Mlatho Wosaoneka" wa Kugwirizanitsa Zinthu Zambiri

Mu gawo la kulumikizana kolondola komanso kupanga zinthu zophatikizika, Polyurethane Acrylate 72021E imayimira ngati muyezo mu zomatira zomangira, zomatira za pulasitiki, ndi zomatira zochiritsika ndi UV. Chifukwa cha kulimba kwake kwapadera, mphamvu zake zambiri, komanso zomatira zapamwamba kwambiri za substrate zambiri, imapereka yankho loyenera komanso lodalirika popanga mafakitale.

Kulimba Kwambiri: Kukana kwa Dynamic Crack

Kapangidwe ka unyolo wosinthasintha wa mamolekyulu kamapatsa guluu kutalika pakadutsa >200% (ASTM D638), zomwe zimapangitsa kuti lizitha kupindika ndi kugwedezeka kwa mafunde ambirimbiri. Izi zimapangitsa kuti likhale labwino kwambiri polumikiza ma hinge a foni yam'manja komanso mafilimu ophatikizika amkati mwa galimoto, zomwe zimathandiza kuthetsa kusweka ndi mavuto a ma adhesives achikhalidwe.

Mphamvu Yowonjezereka: Kulimba Konyamula Katundu

Ndi mphamvu yokoka yoposa 25 MPa (ISO 527) ndi mphamvu yocheka ≥18 MPa (ASTM D1002), 72021E imagwira ntchito bwino kuposa zomatira za polyurethane zokhazikika, zomwe zimapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito pomanga ndi kutseka zida zolemera. Imatsimikizira kuti mawonekedwe ake ndi osasunthika komanso okhalitsa ngakhale atapanikizika ndi makina nthawi zonse.

Kumatira Kosiyanasiyana: Kumatira Kumodzi, Kugwiritsa Ntchito Kambirimbiri

Pokhala ndi mulingo wa 5B adhesion rating (ASTM D3359) pa zitsulo (aluminium, chitsulo), mapulasitiki aukadaulo (PC, ABS), magalasi, ndi mafilimu ophatikizika, 72021E imapanga ma bond olumikizana a molecular-level popanda kufunikira ma primers. Imagwiritsidwa ntchito kwambiri potseka batri ya EV, UV curing ya zida zamagetsi, ndi kukongoletsa filimu, kuthana ndi zovuta za kuphatikizana kwa zinthu zosiyanasiyana komanso delamination.

Kuyambira pa mapangidwe okongola a zamagetsi mpaka kufunikira kwakukulu kwa zida zamafakitale, 72021E imasinthanso muyezo wodalirika wa mgwirizano wa substrate zambiri. Ndi kusinthasintha kwake kofanana ndi kasupe, mphamvu yofanana ndi chitsulo, komanso kumamatira kopanda malire, imagwira ntchito ngati mlatho wosawoneka womwe umathandizira kupanga bwino komanso kulimba kwa nthawi yayitali.
