Phapang ke Efe lipakeng tsa Polyurethane le Epoxy Resin?

1. Ho Kopana le Phapano lipakeng tsa Polyurethane le Epoxy Resin:

The Commonality:

1) Polyurethane le epoxy resin ke likarolo tse peli, 'me lisebelisoa le mekhoa ea ts'ebetso li tšoana hantle;

2) Ka bobeli li na le khanyetso e ntle ea tsitsipano, ha ho ho phatloha, ha ho na ho oa le thepa e 'ngoe;

3) Ka bobeli li na le thepa ea ho hanyetsa kutu ho acid e matla, alkali, letsoai le lintho tse fapaneng tsa oli;

4) Ka bobeli li na le thepa ea ho thibela lerōle, ho thibela metsi, ho hanyetsa ho apara ka holim'a metsi, ho hanyetsa khatello e matla, ho hanyetsa tšusumetso joalo-joalo;

Phapang:

1) Polyurethane (PU) ke polyphenylene diisocyanate le polyether polyol.E hokahane le ho phekoloa ka pel'a catalyst triethylene diamine ho etsa polymer e phahameng.Ha e bapisoa le resin ea epoxy, e chefo ho feta.

Polyurethane e na le litšobotsi tsa ho khomarela hantle, ho kenya letsoho le ho hanyetsa boemo ba leholimo.Ho thatafala ho ka fetoloa ka ho lokisa litaba tsa disocyanate le polyether polyol, 'me e ka sebelisoa ho paka lisebelisoa tse fapaneng tsa elektroniki le tsa motlakase.

2) Epoxy resin ka kakaretso e entsoe ka bisphenol A epoxy resin, e phekolang (amine kapa acid anhydride), moemeli ea thusang, filler, joalo-joalo E na le nako e telele ea ho phekola mocheso oa kamore 'me e ka phekoloa ka ho futhumatsa.Ka mor'a ho phekoloa, e na le matla a holimo a ho kopanya le ho thatafala.Ka kakaretso, e batla e le kholo 'me e ka etsoa pepeneneng ho kenyelletsa li-module tsa motlakase le diode.

Polyurethane e na le khanyetso e ntle ea boemo ba leholimo, ha e phatlohe ka mocheso o phahameng le o tlase, 'me e theko e boima hanyane.

2. Tšebeliso ea polyurethane le epoxy resin:

1) Resin ea polyurethane:

Polyurethane resin ke thepa ea polymer e nang le matla a phahameng, ho hanyetsa meokho, ho hanyetsa ho roala le litšobotsi tse ling;

E sebelisoa joalo karollers,mabanta a tsamaisang thepa, liphaephe, likarolo tsa koloi,lieta, letlalo la maiketsetso, lithapo le mehala le litho tsa maiketsetso tsa bongaka, joalo-joalo;

Bakeng sa ho etsa lihlahisoa tsa polasetiki, lihlahisoa tsa rabara tsa maiketsetso tse sa sebetseng, likhoele tsa maiketsetso, lihlahisoa tsa foam tse thata le tse tenyetsehang, likhomaretsi le likoahelo, joalo-joalo;

E sebelisoa bakeng sa ho qeta holim'a mapolanka a sa tšoaneng, lisebelisoa tsa lik'hemik'hale, lisebelisoa tsa mehala le lisebelisoa le mekhoa e fapaneng ea lipalangoang.

2)Epoxy resin: e ka boela ea sebelisoa ho lira, likhomaretsi, lisebelisoa tse kopaneng, jj.

Ho roala ha epoxy resin ke mofuta oa fatše o matla, o sa senyeheng le o motle, o nang le melemo ea ho se be le mokoloko, sebopeho se tiileng, khanyetso e ntle ea lik'hemik'hale, anti-corrosion, lerōle, tlhokomelo e bonolo le litšenyehelo tse tlaase tsa tlhokomelo.

Merero e fapaneng e ka raloa ho latela litlhoko tsa bareki, joalo ka ho roala ka lera le tšesaane, mokatong o teteaneng oa 1-5mm, mokatong o thibelang ho thella le ho sesa, mokatong oa seretse, anti-static, anti-corrosion floor, jj.

Lihlahisoa li loketse libaka tse fapaneng, joalo ka lithupelo, likamore tsa likhomphutha, libaka tsa polokelo, lilaboratori, li-ward, likamore tsa ho sebetsa, lithupelo, jj.

3. Seaparo sa pele sa topcoat se loketse ho sebelisoa ka ntle, ha sa morao-rao se loketse ho sebelisoa ka hare;

Bofokoli bo boholo ka ho fetisisa kapa bofokoli ba ho qetela ke hore e tšaba mahlaseli a matla a ultraviolet, 'me e tla fetoha mosehla tlas'a mahlaseli a matla a ultraviolet, ke hore, e fela, empa e ke ke ea senyeha ebile e ke ke ea ama tšebeliso;

Leha ho le joalo, ea pele e ntlafetse haholo ho hanyetsa boemo ba leholimo ho feta ea morao-rao, haholo-holo nako ea mosehla ea pele e telele ho feta ea ho qetela, kahoo ea pele e atisa ho sebelisoa bakeng sa litlhoko tsa kaho ea ka ntle.
