Epoxy Resin

1、Intangiriro

Epoxy resin isanzwe ikoreshwa hamwe ninyongeramusaruro.Inyongeramusaruro zirashobora gutoranywa ukurikije imikoreshereze itandukanye.Inyongeramusaruro zisanzwe zirimo Gukiza Umukozi, Guhindura, Kuzuza, Gukora, nibindi.

Umuti ukiza ninyongera yingirakamaro.Niba epoxy resin ikoreshwa nkibifatika, gutwikira, guterana, gukiza bigomba kongerwamo, bitabaye ibyo ntibishobora gukira.Bitewe nibisabwa bitandukanye byo gusaba no gukora, haribisabwa bitandukanye kuri epoxy resin, imiti ikiza, uhindura, wuzuza, diluent nibindi byongeweho.

2 、Guhitamo Epoxy Resin

(1) Hitamo ukurikije Gusaba

① Iyo ikoreshejwe nkibifatika, nibyiza guhitamo resin ifite agaciro ka epoxy yo hagati (0.25-0.45);

② Iyo ikoreshejwe nka castable, nibyiza guhitamo resin ifite agaciro ka epoxy yo hejuru (0.40);

③ Iyo ikoreshejwe nk'igifuniko, resin ifite agaciro gake epoxy (<0.25) iratoranijwe muri rusange.

(2) Hitamo ukurikije Imbaraga za Mechanical

Imbaraga zijyanye nurwego rwo guhuza.Epoxy agaciro ni hejuru, kandi impamyabumenyi ihuza nayo iri hejuru nyuma yo gukira.Epoxy agaciro ni mike kandi urwego rwo guhuza ni ruto nyuma yo gukira.Indangagaciro zitandukanye epoxy nayo izatera imbaraga zitandukanye.

Resin ifite agaciro gakomeye epoxy ifite imbaraga nyinshi ariko iracitse;

Resin ifite agaciro ka epoxy yo hagati ifite imbaraga nziza mubushyuhe bwo hejuru kandi buke;

Resin ifite agaciro gake epoxy ifite imbaraga nke mubushyuhe bwinshi.

(3) Hitamo ukurikije Ibisabwa Mubikorwa

① Kubadakeneye kurwanya ubushyuhe bwinshi nimbaraga, barashobora guhitamo resin ifite agaciro ka epoxy yo hasi ishobora gukama vuba kandi ntibyoroshye kubura.

② Kubakeneye kwinjizwa neza nimbaraga, barashobora guhitamo resin ifite agaciro gakomeye epoxy.

3 、Guhitamo Umuti Ukiza

(1) Ubwoko bwo Gukiza:

Ibikoresho bisanzwe bivura epoxy resin harimo alifatique amine, alicyclicine amine, amine aromatic, polyamide, anhydride, resin na amine ya kaminuza.Mubyongeyeho, bitewe na fotoinitiator, UV cyangwa urumuri nabyo birashobora gutuma epoxy resin ikira.Amine yo gukiza amine muri rusange ikoreshwa mubushyuhe bwicyumba cyangwa gukiza ubushyuhe buke, mugihe anhydride na miti yo kuvura aromatic ikoreshwa mugushushya gukiza.

(2) Igipimo cyumuti ukiza

① Iyo amine ikoreshwa nka agent ihuza, ibarwa kuburyo bukurikira:

Amine dosine = MG / HN

M = uburemere bwa amine;

HN = umubare wa hydrogen ikora;

G = agaciro ka epoxy (epoxy ihwanye na 100 g ya epoxy resin)

Urwego rwo guhindura ntirurenze 10-20%.Niba ikize hamwe na amine ikabije, resin izavunika.Niba igipimo ari gito cyane, gukira ntabwo ari byiza.

② Iyo anhydride ikoreshwa nka agent ihuza, ibarwa kuburyo bukurikira:

Igipimo cya Anhydride = MG (0,6 ~ 1) / 100

M = uburemere bwa anhydride;

G = epoxy agaciro (0,6 ~ 1) ni coefficient yubushakashatsi.

(3) Ihame ryo Guhitamo Umuti Ukiza

Ibisabwa.

Bimwe bisaba guhangana nubushyuhe bwo hejuru, bimwe bisaba guhinduka, ibindi bisaba kurwanya ruswa.Umuti ukiza ukwiye watoranijwe ukurikije ibisabwa bitandukanye.

Uburyo bwo gukiza.

Ibicuruzwa bimwe ntibishobora gushyuha, noneho imiti ikiza yubushyuhe ntishobora gutoranywa.

Ikiringo cyo gusaba.

Igihe cyiswe igihe cyo gusaba bivuga igihe uhereye igihe epoxy resin yongewe hamwe numukozi ukiza kugeza igihe idashobora gukoreshwa.Kubirebire birebire, anhydrides cyangwa imiti yihuta yo gukiza ikoreshwa.

Umutekano.

Mubisanzwe, imiti ikiza ifite uburozi buke nibyiza kandi bifite umutekano kubyara umusaruro.

Igiciro.

4、Guhitamo Guhindura

Ingaruka ya modifier nugutezimbere igituba, gukata kogosha, kurwanya kunama, kurwanya ingaruka no gukora insuline ya epoxy resin.

(1) Abahindura Rusange nibiranga

Rub Polysulfide reberi: kunoza imbaraga zingaruka no kurwanya ibishishwa;

Res Polyamide resin: kunoza ubwitonzi no gukomera;

Inzoga ya Polyvinyl TERT butyraldehyde: kunoza ingaruka ziterwa no gukanika;

B NBR: kunoza ingaruka zo kurwanya ingaruka;

Res Fenolike resin: kunoza ubushyuhe no kurwanya ruswa;

⑥ Polyester resin: kunoza ingaruka zo guhangana ningaruka;

⑦ Urea formaldehyde melamine resin: kongera imiti nimbaraga;

Res Furfural resin: kunoza imikorere igoramye, kunoza aside irwanya;

In Vinyl resin: kunoza imbaraga zo kurwanya no gukuramo imbaraga;

⑩ Isocyanate: kugabanya ububobere buke no kongera amazi;

11 Silicone: kunoza ubushyuhe.

(2) Umubare

Rub Rubber polysulfide: 50-300% (hamwe n'umuti ukiza);

Res Amashanyarazi ya polyamide na fenolike: 50-100%;

③ Polyester resin: 20-30% (utarinze gukiza, cyangwa umubare muto wumuti ukiza kugirango wihute.

Muri rusange, uko uhindura byinshi, niko bigenda bihinduka, ariko ubushyuhe bwo guhindura ubushyuhe bwibicuruzwa bya resin buragabanuka.Kugirango tunonosore imiterere ya resin, hakoreshwa ibikoresho bikaze nka dibutyl phthalate cyangwa dioctyl phthalate.

5、Guhitamo Abuzuza

Igikorwa cyo kuzuza ni ugutezimbere ibintu bimwe na bimwe byibicuruzwa hamwe nubushyuhe bwo gukwirakwiza ubushyuhe bwo gukira.Irashobora kandi kugabanya ingano ya epoxy resin no kugabanya igiciro.Ibyuzuzo bitandukanye birashobora gukoreshwa mubikorwa bitandukanye.Igomba kuba munsi ya mesh 100, kandi igipimo giterwa nikoreshwa ryacyo.Ibisanzwe byuzuza ni ibi bikurikira:

(1) Fibre ya Asibesitosi hamwe nikirahure: kongera ubukana no kurwanya ingaruka;

(2) Ifu ya Quartz, ifu ya farashi, ifu yicyuma, sima, emery: kongera ubukana;

(3) Alumina nifu ya farashi: kongera imbaraga zifatika nimbaraga za mashini;

(4) Ifu ya Asibesitosi, ifu ya silika gel hamwe na sima yubushyuhe bwo hejuru: kunoza ubushyuhe;

(5) Ifu ya Asibesitosi, ifu ya quartz nifu yamabuye: kugabanya igipimo cyo kugabanuka;

.

(7) Ifu ya Graphite, ifu ya talc nifu ya quartz: kunoza imikorere yo kurwanya kwambara no gusiga amavuta;

(8) Emery nibindi bivanaho: kunoza imikorere yo kurwanya kwambara;

(9) Ifu ya Mika, ifu ya farashi nifu ya quartz: kongera imikorere yimikorere;

(10) Ubwoko bwose bwa pigment na grafite: hamwe nibara;

Mubyongeyeho, dukurikije amakuru, umubare ukwiye (27-35%) wa P, As, Sb, Bi, Ge, Sn na Pb oxyde yongewe mubisigara irashobora gukomeza gufatana nubushyuhe bwinshi nigitutu.

6、Guhitamo Abanyamurwango

Imikorere ya diluent ni ukugabanya ubukonje no kunoza uburyo bwa resin.Irashobora kugabanywamo inert kandi ikora ibyiciro bibiri, kandi amafaranga muri rusange ntabwo arenga 30%.Imiyoboro isanzwe irimo diglycidyl ether, polyglycidyl ether, propylene oxyde butyl ether, propylene oxyde phenyl ether, dicyclopropane ethyl ether, triethoxypropane propyl ether, inert diluent, xylene, toluene, acetone, nibindi.

7、Ibisabwa

Mbere yo kongeramo imiti ikiza, ibikoresho byose byakoreshejwe, nka resin, agent ukiza, uwuzuza, uhindura, diluent, nibindi, bigomba kugenzurwa, byujuje ibisabwa bikurikira:

(1) Nta mazi: ibikoresho birimo amazi bigomba kubanza gukama, kandi ibishishwa birimo amazi make bigomba gukoreshwa bike bishoboka.

(2) Isuku: ibirimo umwanda uretse amazi bigomba kuba munsi ya 1%.Nubwo ishobora no gukoreshwa hamwe na 5% -25% byanduye, ijanisha ryibindi bikoresho muri formula bigomba kongerwa.Nibyiza gukoresha reagent urwego ruto.

(3) Igihe cyagenwe: Birakenewe kumenya niba ibikoresho bitemewe.
