NBR PVC NITRILE RUBBER FOAM INSULATION URUPAPURO

Ni ubuhe buryo bwa nitrile rubber umuyoboro wakozwe?

Imiyoboro ya nitrile reberi ikozwe muri nitrile reberi cyangwa Buna R, elastomer ikoreshwa cyane.Rubber ya Nitrile igizwe na copolymers idahagije ya acrylonitrile na monomers ya butadiene.Imiterere ya chimique na physique ya nitrile reberi iratandukanye ishingiye kuri make ya polymer.

Ni irihe tandukaniro riri hagati ya NBR / PVC na EPDM Insulation?

Gufunga ingirabuzimafatizo ya elastomeric, izwi kandi nka reberi, imaze imyaka igera kuri 70 iboneka mubucuruzi.Bikunze gusobanurwa kugirango ushireho sisitemu yubukanishi munsi yubukonje nka HVAC, VRF / VRV, gukonjesha, amazi akonje, gazi yubuvuzi, hamwe nuyoboro wamazi akonje.

Guhitamo mubikoresho byubaka, gusesengura no kugereranya nibyingenzi kugirango uhitemo neza ibicuruzwa.Waba uhitamo ibikoresho byo kwambika ikirere, cyangwa igicuruzwa gikingira sisitemu ya HVAC cyangwa pompe, kwemeza ibisabwa hamwe nibisabwa byubaka byujujwe ningirakamaro mugushiraho neza kandi byujuje ibisabwa.Ibihinduka nkubushyuhe, ubucucike, ubwikorezi bwamazi, cyangwa UV irwanya byose birashobora kugira ingaruka nziza muguhitamo umushinga.

Muburyo bwo gukanika imashini, Kingflex ifite amahitamo hafi ya progaramu yose kandi ikenewe.Mu buryo butandukanye n’abandi bakora inganda, Kingflex ikora ibikoresho bibiri bikunze gukoreshwa muri Elastomeric insulation ya HVAC, amazi akonje, hamwe na sisitemu yo gukonjesha ishingiye kuri rubber ya nitrile butadiene (NBR) hamwe na tekinoroji ya Ethylene propylene diene monomer (EPDM).Izi furo zombi za elastomeric ziroroshye, selile zifunze, kandi zifite imbaraga nyinshi zo guhangana nubushuhe n’amazi.Mubyukuri, amazi yabo yinjira ni make kuburyo badakenera muri rusange amazi adasubira inyuma.Na none, hamwe n’imyuka myinshi irwanya imyuka hamwe nubuso bwo hejuru, iyi furo ya elastomeric ikora akazi keza mukurinda kwangirika kwubutaka.

Imbaraga Zinyuranye na Porogaramu zitandukanye

Nubwo NBR na EPDM bisa nkaho, hari itandukaniro ryingenzi.NBR ni polymer itavanze, mugihe EPDM ari polymer aromatic.Byongeye kandi, NBR ikorwa hifashishijwe monomers ya acrylonitrile na butadiene, mugihe EPDM ikorwa hakoreshejwe Ethylene, propylene na diene comonomer.Irindi tandukaniro rikomeye mubijyanye no gusaba, ni uko NBR ifite ubushyuhe bwa -40F kugeza 180F, mugihe EPDM ifite ubushyuhe bwagutse bwa -65 ° F kugeza 250 ° F)

NBR ihagaze yonyine nka elastomer yamavuta- na peteroli.Birazwi kandi kubungabunga umutekano wacyo mubushyuhe buke.Ku rundi ruhande, EPDM ni ubushyuhe, ozone, na UV irwanya UV ifite imbaraga zikomeye, kurwanya gusaza, hamwe no kurwanya abrasion, ndetse no kugira umwotsi muke muke hamwe n’ikigereranyo cy’umuriro cyane cyane kuri 1-1 / 2 na 2 ”ubunini.

Ibikoresho byombi byifashishwa mu kubika ibyuma biva mu bwoko bwa Kingflex byagaragaye ko ari ubundi buryo bwo guhinduranya fiberglass kuri HVAC, amazi akonje, hamwe na sisitemu ya firigo (imiyoboro, pompe, tank, imiyoboro, hamwe na serefe) bitewe n’imiterere ya hydrophobique, imiterere ya selile, kandi yubatswe. imyuka idindiza.
