Kedu ihe dị iche n'etiti polyurethane na epoxy resin?

1. Ihe jikọrọ na ọdịiche dị n'etiti polyurethane na epoxy resin:

Ihe jikọrọ:

1) Polyurethane na epoxy resin bụ akụkụ abụọ, na akụrụngwa na ụzọ ọrụ bụ otu ihe ahụ;

2) Ha abụọ nwere ezigbo nguzogide nkwụsịtụ, enweghị mgbawa, enweghị ọdịda na ihe ndị ọzọ;

3) Ha abụọ nwere njirimara nke iguzogide corrosion na acid siri ike, alkali, nnu na mmanụ dị iche iche;

4) Ha abụọ nwere njirimara nke uzuzu uzuzu, mmiri na-ekpuchi mmiri, nkwụsi ike elu elu, nrụgide nrụgide siri ike, mmetụta nkwụsị na ihe ndị ọzọ;

Ihe dị iche:

1) Polyurethane (PU) bụ polyphenylene diisocyanate na polyether polyol.A na-ejikọta ya na obe ma gwọọ ya na ọnụnọ nke triethylene diamine na-eme ka ọ bụrụ polymer dị elu.E jiri ya tụnyere resin epoxy, ọ na-egbu egbu karịa.

Polyurethane nwere njirimara nke ezigbo adhesion, mkpuchi na iguzogide ihu igwe.Enwere ike ịgbanwe ihe siri ike site n'ịgbanwe ọdịnaya nke diisocyanate na polyether polyol, a pụkwara iji ya mee ihe na nkwakọ ngwaahịa dị iche iche na eletrik.

2) Epoxy resin bụ ihe mejupụtara bisphenol A epoxy resin, onye na-agwọ ọrịa (amine ma ọ bụ acid anhydride), onye na-enyere aka, filler, wdg.Mgbe ọgwụgwọ gasịrị, ọ nwere nnukwu njikọ ike na ike.N'ozuzu, ọ dị oke ibu ma nwee ike ime ka ọ pụta ìhè iji kpuchie modul eletriki na diodes.

Polyurethane nwere nguzogide ihu igwe ka mma, ọ naghị agbawa n'ogo dị elu na nke dị ala, ma dị ntakịrị ọnụ.

2. ojiji nke polyurethane na epoxy resin:

1) Polyurethane resin:

Polyurethane resin bụ ihe polymer nwere ike dị elu, nkwụsi ike na-adọka, na-eyi nguzogide na njirimara ndị ọzọ;

Ejiri ya dị karollers,ebuka eriri, hoses, akpaaka akụkụ,akpụkpọ ụkwụ, akpụkpọ anụ sịntetik, wires na eriri na akụkụ ahụ ahụike, wdg;

Maka imepụta ngwaahịa rọba, ngwaahịa roba sịntetik na-eguzogide ọgwụ, eriri sịntetik, ngwaahịa ụfụfụ siri ike na nke na-agbanwe agbanwe, nrapado na mkpuchi, wdg;

A na-eji ya emecha ihe dị iche iche osisi, akụrụngwa kemịkalụ, ngwa nkwukọrịta na ngwa na ụzọ dị iche iche njem.

2)Epoxy resin: nwekwara ike iji na mkpuchi, nrapado, ihe ngwakọta, wdg.

Epoxy resin mkpuchi bụ ụdị ike dị elu, nke na-eguzogide ọgwụ na ala mara mma, nke nwere uru nke enweghị nkebi, ihe siri ike, ezigbo nguzogide kemịkalụ, mgbochi corrosion, uzuzu uzuzu, mmezi dị mma na ọnụ ahịa dị ala.

Enwere ike ịhazi atụmatụ dị iche iche dị ka ihe ndị ahịa chọrọ si dị, dị ka mkpuchi mkpuchi nke dị mkpa, 1-5mm n'ala na-edozi onwe ya, mgbochi skid na eyi na-eguzogide, ala ngwa agha, mgbochi static, mgbochi corrosion ala, wdg.

Ngwaahịa dabara adaba maka ebe dị iche iche, dị ka ụlọ ọrụ, ụlọ kọmputa, ụlọ nkwakọba ihe, ụlọ nyocha, ngalaba, ụlọ ọrụ, ụlọ ọrụ, wdg.

Nnukwu adịghị ike ma ọ bụ adịghị ike nke ikpeazụ bụ na ọ na-atụ egwu radieshon ultraviolet siri ike, ọ ga-agbanwekwa edo edo n'okpuru radieshon ultraviolet siri ike, ya bụ, na-agwụ, ma ọ gaghị emebi ma ọ gaghị emetụta ojiji;

Otú ọ dị, nke mbụ na-emewanyewanye nke ọma na nkwụsị ihu igwe karịa nke ikpeazụ, karịsịa oge edo edo nke mbụ dị ogologo karịa nke ikpeazụ, ya mere, a na-ejikarị nke mbụ eme ihe maka ihe owuwu n'èzí.
