Ubumenyi bwibanze bwa Epoxy Resins na Epoxy Adhesives

(I) Igitekerezo cyaepoxy resin

Epoxy resin bivuga imiterere y'urunigi rwa polymer irimo amatsinda abiri cyangwa menshi ya epoxy yibice bya polymer, ni ibya resmosetting resin, uhagarariye resin ni bisphenol Ubwoko bwa epoxy resin.

.

1. Umuntu ku giti cye epoxy resin yo gusaba agaciro ni make cyane, igomba gukoreshwa ifatanije numukozi ukiza kugirango igire agaciro keza.

2.

3. Gukiza kugabanuka ni bito, muri epoxy epoxy resin yifata kugabanuka ni ntoya, nayo ni epoxy resin yifata ikiza ifata hejuru imwe mumpamvu.

4. Mu mazi yo mu nyanja, peteroli, kerosene, 10% H2SO4, 10% HCl, 10% HAc, 10% NH3, 10% H3PO4 na 30% Na2CO3 irashobora gukoreshwa mumyaka ibiri; no muri 50% H2SO4 na 10% kwibiza HNO3 mubushyuhe bwicyumba igice cyumwaka; 10% NaOH (100 ℃) kwibiza ukwezi kumwe, imikorere ntigihinduka.

5. Gukoresha amashanyarazi meza cyane: kumeneka imbaraga za epoxy resin irashobora kurenza 35kv / mm 6. Imikorere myiza, ingano yibicuruzwa, kwihanganira neza no kwinjiza amazi make. Bisphenol A ubwoko bwa epoxy resin ibyiza nibyiza, ariko kandi bifite ibibi byayo: ①. Gukoresha ibishishwa, bigaragara ko bitameze neza mubwubatsi ②. Ibikoresho byakize biroroshye, kurambura ni bito. ③. Imbaraga nke. ④. Kurwanya nabi ubukanishi nubushyuhe.

(III) gusaba no guteza imbereepoxy resin

1.

. Irashobora gukoreshwa cyane mubikoresho bitwara imiyoboro, imodoka, ubwato, ikirere, icyogajuru, ibikinisho, ubukorikori nizindi nganda. Industry Inganda zikoresha amashanyarazi na elegitoronike: epoxy resin yometse irashobora gukoreshwa mubikoresho byogukoresha amashanyarazi, nkibikosora, transformateur, kubumba kashe; gufunga no kurinda ibikoresho bya elegitoroniki; ibicuruzwa bya elegitoroniki, kubika no guhuza; gufunga no guhuza bateri; capacator, résistoriste, inductors, hejuru yumwenda. Jew Imitako ya zahabu, ubukorikori, ibicuruzwa bya siporo: birashobora gukoreshwa kubimenyetso, imitako, ibimenyetso byerekana ibicuruzwa, ibyuma, racket, ibikoresho byo kuroba, ibicuruzwa bya siporo, ubukorikori nibindi bicuruzwa. Industry Inganda za Optoelectronic: zirashobora gukoreshwa mugushira hamwe, kuzuza no guhuza diode itanga urumuri (LED), imiyoboro ya digitale, pigiseli ya pigiseli, ibyuma bya elegitoronike, amatara ya LED nibindi bicuruzwa. Inganda zubaka: Bizanakoreshwa cyane mumuhanda, ikiraro, hasi, imiterere yicyuma, ubwubatsi, gutwikira urukuta, urugomero, kubaka ubwubatsi, gusana ibisigisigi ndangamuco nizindi nganda. ⑥ Ibifatika, ibidodo hamwe nibigize umurima: nkibikoresho byumuyaga wa turbine, ubukorikori, ubukerarugendo, ibirahuri nubundi bwoko bwo guhuza ibintu, impapuro za karuboni yibikoresho, ibikoresho bya mikorobe bifunga nibindi.

(IV) Ibirangaepoxy resin ifata

1. (gukomera).

2. Viscosity (Viscosity): ni imbere yo guterana imbere imbere ya colloid itemba, agaciro kayo kagenwa nubwoko bwibintu, ubushyuhe, kwibanda hamwe nibindi bintu.

Igihe cya Gel.

Thixotropy.

Gukomera: bivuga kurwanya ibikoresho kubintu byo hanze nko gushushanya no gushushanya. Ukurikije uburyo butandukanye bwikizamini Shore (Shore) gukomera, Brinell (Brinell) gukomera, Rockwell (Rockwell) gukomera, Mohs (Mohs) gukomera, Barcol (Barcol) gukomera, Vickers (Vichers) gukomera nibindi. Agaciro k'ubwoko bw'igeragezwa n'ubukomezi bujyanye nibisanzwe bikoreshwa mugupima ubukana, Imiterere yikizamini cya Shore iroroshye, ikwiriye kugenzurwa n’umusaruro, Ikizamini cyo gukomera ku nkombe gishobora kugabanywa mu bwoko bwa A, ubwoko bwa C, ubwoko bwa D, Ubwoko bwa A bwo gupima colloid yoroshye, C na D-yo gupima igice cyakomeye kandi gikomeye.

Ubushyuhe bwo hejuru: gukurura molekile mumazi kugirango molekile hejuru yimbere yimbere imbaraga, izo mbaraga zituma amazi ashoboka cyane kugirango agabanye ubuso bwayo hamwe no gukora ibangikanye nubuso bwimbaraga, bizwi nkuburemere bwubutaka. Cyangwa gukwega hagati yibice bibiri byegeranye byubuso bwamazi kuri burebure, ni kwigaragaza imbaraga za molekile. Igice cyo guhagarika ubuso ni N / m. Ingano yubushyuhe bwo hejuru ifitanye isano na kamere, ubuziranenge nubushyuhe bwamazi.

3. Kugaragaza ibirangaepoxy resin ifatanyuma yo gukiza ibintu byingenzi ni: kurwanya, voltage, kwinjiza amazi, imbaraga zo kwikuramo, imbaraga za tensile (tensile), imbaraga zogosha, imbaraga zishishwa, imbaraga zingaruka, ubushyuhe bwo kugoreka ubushyuhe, ubushyuhe bwinzibacyuho yimbere, guhangayikishwa n’imiti, kuramba, kugabanuka kwa coefficient, ubushyuhe bwumuriro, gutwara amashanyarazi, ikirere, kurwanya gusaza, nibindi.

Kurwanya: Sobanura ibintu biranga ibintu birwanya ubusanzwe hamwe no guhangana nubutaka. Kurwanya Ubuso nubuso bumwe hagati ya electrode ebyiri zapimwe agaciro kangana, igice ni Ω. Imiterere ya electrode nagaciro kayirwanya irashobora kubarwa muguhuza ubuso burwanya ubuso buri gice. Kurwanya amajwi, bizwi kandi ko birwanya amajwi, coefficient de coiffe, bivuga agaciro kokurwanya binyuze mububyimbye bwibintu, ni ikimenyetso cyingenzi cyo kuranga amashanyarazi yibikoresho bya dielectric cyangwa insulation. Nibipimo byingenzi biranga amashanyarazi yibikoresho bya dielectric cyangwa insulasiyo. 1cm2 dielectric irwanya imiyoboro yamenetse, igice ni Ω-m cyangwa Ω-cm. binini birwanya ubukana, nibyiza biranga insulasiyo.

Umuvuduko wa gihamya. Kora insulator kumeneka ya voltage yo hasi cyane yitwa ikintu cyo kumeneka voltage. Kora mm 1 yubugari bwibikoresho byo kumeneka, ukeneye kongeramo voltage kilovolts bita insulasiyo yibikoresho byihanganira imbaraga za voltage, byitwa kwihanganira voltage, igice ni: Kv / mm. kubika ibintu hamwe nubushyuhe bifitanye isano ya hafi. Ubushyuhe buri hejuru, niko imikorere mibi yo kubika ibintu. Kugirango hamenyekane imbaraga zo gukumira, buri kintu gikingira gifite ubushyuhe ntarengwa bwemewe bwo gukora, muri ubu bushyuhe buri munsi, burashobora gukoreshwa neza mugihe kirekire, kuruta ubu bushyuhe buzasaza vuba.

Kwinjiza amazi: Ni igipimo cyerekana urugero ibintu bifata amazi. Bivuga kwiyongera kw'ijana mubwinshi bwibintu byinjijwe mumazi mugihe runaka mubushyuhe runaka.

Imbaraga: Imbaraga za tensile nizo mpagarike ntarengwa iyo gel irambuye kumeneka. Bizwi kandi nkingufu zingutu, imbaraga zingana, imbaraga zingana, imbaraga zingana. Igice ni MPa.

Imbaraga zogosha: bizwi kandi nkimbaraga zogosha, bivuga igice gihuza igice gishobora kwihanganira umutwaro ntarengwa ugereranije nu gace gahuza, gakunze gukoreshwa na MPa.

Imbaraga: bizwi kandi nkibishishwa byigishishwa, nigipimo kinini cyangiritse umutwaro kuri buri bugari bushobora kwihanganira, ni igipimo cyumurongo wubushobozi bwingufu, igice ni kN / m.

Kurambura: bivuga colloid mumbaraga zingutu munsi yibikorwa byuburebure bwiyongera muburebure bwambere bwijanisha.

Ubushyuhe bwo gutandukana.

Ubushyuhe bwikirahure.

Kugabanuka: bisobanuwe nkijanisha ryikigereranyo cyo kugabanuka kubunini mbere yo kugabanuka, no kugabanuka ni itandukaniro riri hagati yubunini mbere na nyuma yo kugabanuka.

Guhangayika imbere: bivuga kubura imbaraga zo hanze, colloid (material) bitewe no kuba hari inenge, ihinduka ryubushyuhe, ibishishwa, nizindi mpamvu zitera guhangayika imbere.

Kurwanya imiti: bivuga ubushobozi bwo kurwanya aside, alkalis, umunyu, umusemburo nindi miti.

Kurwanya umuriro: bivuga ubushobozi bwibikoresho byo kurwanya gutwikwa iyo uhuye numuriro cyangwa kubuza gukomeza gutwikwa iyo kure yumuriro.

Kurwanya ikirere: bivuga ibintu byerekana urumuri rwizuba, ubushyuhe nubukonje, umuyaga n imvura nibindi bihe byikirere.

Gusaza. byitwa gusaza. Ikintu cyimpinduka cyitwa gusaza.

Dielectric ihoraho: bizwi kandi nk'igipimo cya capacitance, igipimo cyatewe (Permittivity). Yerekeza kuri buri "mubare wububiko" bwikintu, muri buri gice cy "ubushobozi bwa gradient" irashobora kuzigama "ingufu za electrostatike" (Ingufu za Electrostatike) zingana iki. Iyo colloid "permeability" nini (ni ukuvuga, ireme ryiza), na bibiri byegeranye nakazi ka none, biragoye kugera ku ngaruka zo gukingirwa byuzuye, mu yandi magambo, birashoboka cyane ko bitanga urugero runaka. Kubwibyo, dielectric ihoraho yibikoresho byigenga muri rusange, bito nibyiza. Amazi ya dielectric yamazi ni 70, ubushuhe buke cyane, bizatera impinduka zikomeye.

4. Byinshi muriepoxy resin ifatani ubushyuhe bwo gushiraho ubushyuhe, bufite ibintu byingenzi bikurikira: uko ubushyuhe buri hejuru niko gukira byihuse; ingano ivanze ya byinshi byihuse gukira; inzira yo gukira ifite exothermic phenomenon.
