Ka lebaka la ts'ebetso ea eona e phahameng, e na le tšekamelo e kholo ea ho nkela liphutheloana tsa tšepe, ceramic le khalase sebaka sa setso.

4. Plastiki ea laminated epoxy e sebelisoa haholo masimong a elektronike le a motlakase. Tsoelo-pele ea epoxy copper clad laminate e potlakile ka ho khetheha, 'me e fetohile e' ngoe ea lisebelisoa tsa motheo indastering ea elektronike. Ho phaella moo, liphahlo tsa epoxy insulating, li-adhesive le li-adhesive tsa motlakase li sebelisoa haholo.

5. Lipolasetiki tsa boenjiniere le lisebelisoa tse kopantsoeng: lipolasetiki tsa boenjiniere ba epoxy haholo-holo li kenyelletsa lisebelisoa tsa ho bopa epoxy, li-plastiki tsa epoxy laminated le li-epoxy foam tse sebelisetsoang ho bopa ka khatello e phahameng. Lipolasetiki tsa boenjiniere ba epoxy le tsona li ka nkuoa e le mofuta oa lisebelisoa tse akaretsang tsa epoxy composite. Li-composites tsa epoxy haholo-holo li kenyelletsa polasetiki e matlafalitsoeng ea khalase ea epoxy (motsoako o akaretsang) le likarolo tsa sebopeho sa epoxy, joalo ka li-profiles tsa epoxy, lihlahisoa tsa rotary tse se nang maqeba le likarolo tse sebetsang hantle haholo. Epoxy composite ke thepa ea bohlokoa ea meralo le e sebetsang indastering ea lik'hemik'hale, sefofane, sefofane, sesole le masimo a mang a theknoloji e phahameng.

6. Lisebelisoa tsa sechaba li sebelisoa haholo-holo e le li-anti-corrosion floor, seretse sa epoxy le lihlahisoa tsa konkreite, sebaka se phahameng sa marang-rang le sefofane sa boema-fofane, lisebelisoa tsa ho lokisa ka potlako, lisebelisoa tsa grouting bakeng sa ho matlafatsa motheo, li-adhesive le liphahlo, joalo-joalo.

Thepa le Sebopeho

Lintho tse phahameng tsa mechine. Mokelikeli oa Epoxy Resin e na le momahano e matla le sebopeho se teteaneng sa limolek'hule, kahoo thepa ea eona ea mochini e phahame ho feta ea li-resin tse tloaelehileng tsa thermosetting tse kang phenolic resin le polyester e sa tsitsang.

Ho khomarela ka matla. Sistimi ea pheko ea resin ea epoxy e na le sehlopha sa epoxy, sehlopha sa hydroxyl, bond ea ether, bond ea amine, bond ea ester le lihlopha tse ling tsa polar tse nang le ts'ebetso e kholo, e fanang ka thepa e phekotsoeng ea epoxy ka ho khomarela hantle ho likarolo tsa polar tse kang tšepe, ceramics, khalase, konkreite. le patsi.

Ts'ebetso e ntle ea ts'ebetso: epoxy resin ha e le hantle ha e hlahise li-volatile tse tlase tsa molek'hule ha e phekoloa, kahoo e ka bōptjoa tlas'a khatello e tlaase kapa khatello ea ho kopana. Epoxy resin E44 e ka sebelisoa le mefuta e fapaneng ea pheko ho etsa litlolo tse se nang solvent, tse tiileng tse phahameng, tse nang le phofo, liphahlo tse thehiloeng metsing le tse ling tse baballang tikoloho.

Motlakase o motle ka ho fetisisa: Epoxy resin ke e 'ngoe ea mefuta e metle ka ho fetisisa ea resin ea thermosetting e nang le thepa ea motlakase e mahareng.

Botsitso bo botle le khanyetso ea lik'hemik'hale. The epoxy resin ntle le litšila tse kang alkali le letsoai ha ho bonolo ho senyeha. Hafeela e bolokiloe hantle (e tiisitsoe, e se na mongobo le mocheso o phahameng), nako ea polokelo ke 1 selemo. E ntse e ka sebelisoa haeba e feta tlhahlobo ka mor'a ho felloa ke nako. Motsoako oa pheko oa epoxy o na le botsitso bo botle ba lik'hemik'hale. Ho hanyetsa ho bola ha eona ho alkali, asiti, letsoai le mecha e meng ea litaba ho molemo ho feta ea resin ea unsaturated polyester, resin ea phenolic le li-resin tse ling tsa thermosetting. Ka hona, epoxy resin e sebelisoa haholo e le anti-corrosion primer. Hobane resin ea epoxy e phekotsoeng e na le sebopeho sa marang-rang se mahlakore a mararo 'me e hanana le ho kenella ha oli, e sebelisoa haholo lerakong le kahare la litanka tsa oli, litanka tsa oli le lifofane.
