Polyurethane Acrylate 72021E: Te "Piriti Kāore e Kitea" mō te Hononga Maha-Papa

I roto i te ao o te hononga tika me te auahatanga rauemi hiato, ko te Polyurethane Acrylate 72021E te paearu matua mō ngā piripiri hanganga, te hononga pepa kirihou, me ngā piripiri UV-whakaora. Nā tōna pakari tino pai, tōna kaha teitei, me tōna piri maha-papa, ka whakaratohia he otinga taurite me te pono mō te hanga ahumahi.

Te Pakaritanga o te Pakari: Te Ātete Ngatata Hihiri

Mā te hoahoa mekameka ngota ngota ngāwari ka roa ake te piri i te whatinga o te >200% (ASTM D638), ka taea ai e ia te tu atu i ngā mano tini piko me ngā wiri auau teitei. Nā tēnei ka tino pai mō te here hononga waea atamai me ngā kiriata hiato o roto o te motuka, ka whakakorea te pakarukaru me ngā raruraru pakaru o ngā piri noa.

Kaha Whakarei: Te Pumau o te Kawenga

Me te kaha kume neke atu i te 25 MPa (ISO 527) me te kaha kutikuti ≥18 MPa (ASTM D1002), ka eke te 72021E ki runga ake i ngā piripiri polyurethane paerewa, ā, he pai mō te here hanganga i roto i te hanganga me te hiri taputapu taumaha. Ka whakarite i tētahi atanga maeneene, roa te mau i raro i te ahotea miihini tonu.

Piripiri Maha-Wāhanga: Kotahi te Piripiri, He Maha ngā Whakamahinga

Mā te whiwhi i te whakatauranga piri 5B (ASTM D3359) ki ngā konganuku (konumohe, maitai), ngā kirihou hangarau (PC, ABS), te karāhe, me ngā kiriata hiato, ka hangaia e te 72021E he hononga honohono taumata-ngota me te kore e hiahiatia he paninga tuatahi. He whānuitia te whakamahinga i roto i te hiri pākahiko EV, te whakamaroke UV mō ngā wāhanga hiko, me te whakakikorua kiriata whakapaipai, hei wikitoria i ngā wero o te here me te wehewehe rauemi rerekē.

Mai i ngā hoahoa ātaahua o ngā hikohiko kaihoko ki ngā tono kawenga nui o ngā taputapu ahumahi, ka tautuhia anō e te 72021E te paerewa pono mō te hononga maha-papa. Mā tōna ngāwari rite ki te puna, tōna kaha rite ki te maitai, me tōna piri mutunga kore, ka mahi hei piriti e kore e kitea e whakarei ake ana i te pai o te whakaputa me te roa o te mau.
