Yintoni Umahluko phakathi kwePolyurethane kunye ne-Epoxy Resin?

1. Ukuqheleka kunye noMahluko phakathi kwePolyurethane kunye ne-Epoxy Resin:

I-Commonality:

1) I-polyurethane kunye ne-epoxy resin zizinto ezimbini, kwaye izixhobo kunye neendlela zokusebenza ziyafana;

I-2) Bobabini banokuxhathisa okulungileyo, akukho kuphazamiseka, akukho ukuwa kunye nezinye iipropathi;

3) Zombini zineempawu zokumelana ne-corrosion kwi-asidi eqinile, i-alkali, ityuwa kunye nezinto ezahlukeneyo zeoli;

I-4) Zombini zineempawu zothuli, ukungabikho kwamanzi, ukuxhathisa ukugqoka umphezulu, ukuxhatshazwa koxinzelelo olunzima, ukuchasana kwempembelelo kunye nokunye;

Umehluko:

1) I-polyurethane (PU) yi-polyphenylene diisocyanate kunye ne-polyether polyol.Idityaniswe ngokunqamlezileyo kwaye iphiliswe phambi kwe-catalyst triethylene diamine ukwenza i-polymer ephezulu.Xa kuthelekiswa ne-epoxy resin, inetyhefu ngakumbi.

I-polyurethane ineempawu zokubambelela kakuhle, ukugquma kunye nokumelana nemozulu.Ubunzima bunokutshintshwa ngokulungelelanisa umxholo we-disocyanate kunye ne-polyether polyol, kwaye ingasetyenziselwa ukupakishwa kwezixhobo ezahlukeneyo zombane kunye nombane.

2) I-epoxy resin ngokuqhelekileyo iqulethwe yi-bisphenol I-epoxy resin, i-ejenti yokunyanga (i-amine okanye i-acid anhydride), i-agent encedisayo, i-filler, njl. Inexesha elide lokunyanga kwiqondo lokushisa eliqhelekileyo kwaye linokunyangwa ngokufudumeza.Emva kokunyanga, inamandla okudibanisa okuphezulu kunye nobunzima.Ngokubanzi, likhulu kwaye linokwenziwa elubala ukufaka iimodyuli zombane kunye neediode.

Ipolyurethane inokumelana nemozulu engcono, ayiqhekeki kumaqondo obushushu aphezulu naphantsi, kwaye ibiza kakhulu.

2.ukusetyenziswa kwe-polyurethane kunye ne-epoxy resin:

1) Polyurethane resin:

I-polyurethane resin yinto yepolymer enamandla amakhulu, ukuxhathisa ukukrazula, ukuxhatshazwa kokugqoka kunye nezinye iimpawu;

Isetyenziswa njengeiirola,amabhanti okuhambisa, imibhobho, iindawo zemoto,imiphantsi yezihlangu, ngesikhumba sokwenziwa, iingcingo kunye neentambo kunye namalungu angengowamayeza ezonyango, njl.;

Ukwenziwa kweemveliso zeplastiki, iimveliso zerabha zokwenziwa ezinxitywayo, iintsinga zokwenziwa, ezomeleleyo kunye neemveliso zamagwebu eziguquguqukayo, izinto zokuncamathelisa kunye neengubo, njl.;

Isetyenziselwa ukugqitywa komphezulu wezinto ezahlukeneyo zomthi, izixhobo zekhemikhali, izixhobo zonxibelelwano kunye nezixhobo kunye neendlela ezahlukeneyo zothutho.

2)I-epoxy resin: ingasetyenziselwa ukugquma, i-adhesives, izinto ezidibeneyo, njl.

I-epoxy resin coating luhlobo lomgangatho ophezulu, ukunxiba-resistant kunye nomgangatho omhle, oneenzuzo zokungenamthungo, ukuthungwa okuqinileyo, ukuchasana kakuhle kweekhemikhali, ukuchasana nokubola, ukungabikho kothuli, ukugcinwa ngokufanelekileyo kunye neendleko zokugcinwa okuphantsi.

Izikimu ezahlukeneyo zinokuthi ziyilwe ngokweemfuno zabathengi, ezinje nge-coating-layer-layer, i-1-5mm engqindilili yomgangatho wokuzilinganisa, i-anti-skid kunye nomgangatho ongaguqukiyo, umgangatho wodaka, i-anti-static, i-anti-corrosion floor, njl.

Iimveliso zifanelekile kwiindawo ezahlukeneyo, ezifana neendibano zocweyo, amagumbi eekhompyuter, iindawo zokugcina iimpahla, iilebhu, iiwadi, amagumbi okusebenzela, iindibano zocweyo, njl.

3. I-topcoat yangaphambili ifanelekile ukusetyenziswa kwangaphandle, ngelixa le yokugqibela ifanelekile ukusetyenziswa kwangaphakathi;

Ubuthathaka obukhulu okanye ukungonakali kokugqibela kukuba ukwesaba imisebe ye-ultraviolet enamandla, kwaye iya kuba phuzi phantsi kwemitha ye-ultraviolet enamandla, oko kukuthi, iphelile, kodwa ayiyi kubola kwaye ayiyi kuchaphazela ukusetyenziswa;

Nangona kunjalo, i-yangaphambili iphuculwe kakhulu ekuchaseni imozulu kuneyokugqibela, ngakumbi ixesha elityheli langaphambili lide kakhulu kunelo lamva, ngoko yangaphambili isoloko isetyenziselwa iimfuno zokwakha zangaphandle.
