Ịfesa Epoxy na mkpuchi Halar

I. Gịnị bụ mkpuchi mmanụ epoxy?

Mkpuchi mmiri Epoxy bụ ihe mkpuchi nwere akụkụ abụọ nwere resin epoxy dị ka ihe bụ isi na-emepụta ihe nkiri. A na-etinye ya n'elu ígwè site na ịgbasa ma ọ bụ ịchacha ya iji mepụta oyi akwa nchebe. A na-eji nrapado siri ike na iguzogide peeling cathodic mara ya. Otu mkpuchi nwere ike ịrụpụta nnukwu ihe owuwu (ruo 1250 microns) na-enweghị ịda ada. A na-agwọ ya na okpomọkụ ụlọ ma dịkwa mfe ịrụ. Mkpuchi Epoxy dị mma maka mbuze na nchedo nchara nke ihe mkpuchi pipeline, akpa, ọkpọkọ na valvụ na akụrụngwa ndị ọzọ, okpomọkụ ọrụ na-adịkarịkwa ihe dị ka 120°C.

II. Gịnị bụ mkpuchi Halar?

Halar bụ aha azụmaahịa nke mkpuchi ntụ ntụ ECTFE (ethylene-chlorotrifluoroethylene copolymer), nke bụ ihe nwere fluorine dị elu. A na-etinye ya n'elu ihe ndị e ji ígwè mee site na usoro ịgba mmiri electrostatic, ebe agbaze n'etiti 220-245°C na okpomọkụ kachasị elu nke ojiji nke 150°C.

nke atọ.Kedu ihe dị iche na nguzogide kemịkalụ n'etiti ha abụọ?

Mkpuchi Halar zuru oke ma dị mma karịa na iguzogide kemịkalụ. Ọ nwere ike iguzogide ihe fọrọ nke nta ka ọ bụrụ asịd siri ike niile, ntọala siri ike na ihe mgbaze oZrganic nwere oke pH nke 1-14. Enwere ike itinye ya na kemịkalụ dị oke njọ dịka 98% sulfuric acid concentrated na 37% hydrochloric acid na 121°C ruo ụbọchị 30. Mgbanwe ibu mkpuchi ahụ erughị 1% na ihe onwunwe igwe anaghị agbanwe agbanwe. O nwere ezigbo hydrophobicity na nguzogide ịbanye, nke nwere ike igbochi mgbasa ozi na-emebi emebi ịbanye na mkpuchi ahụ ma ruo na substrate ígwè. Ọ bụ ezie na mkpuchi epoxy nwekwara ezigbo nguzogide kemịkalụ, ikike ha iguzogide asịd siri ike (dịka sulfuric acid, hydrochloric acid) na okpomọkụ dị elu adịghị ike nke ukwuu karịa mkpuchi Halar.

IV.Kedu nke ka mma n'ihe gbasara arụmọrụ elu na ogologo oge?

Elu mkpuchi Halar dị ezigbo nro (nkezi oke Ra dị ihe dị ka 22nm), nke ka mma karịa mkpuchi epoxy. Elu dị nro nwere ike igbochi nrapado na nchịkọta nke ihe ndị dị na nnu ígwè nke ọma, belata mmepụta nke biofilm, belata ihe egwu nke oghere pin, ma melite ntụkwasị obi mgbochi ire ere. Na mgbakwunye, mkpuchi Halar siri ike, na-eguzogide ọkọ ma na-eguzogide mmetụta, ma nwee ike iguzogide UV siri ike, yabụ ọ gaghị agbaze ma ọ bụ gbazee mgbe ejiri ya n'èzí.

V. Kedu otu esi ahọrọ ngwọta mkpuchi kwesịrị ekwesị?

A na-atụ aro ka ịhọrọ mkpuchi Halar mgbe——

1. Metụ aka na asịd siri ike, alkali siri ike ma ọ bụ kemịkalụ na-emebi ihe dị iche iche;

2. Okpomọkụ ọrụ karịrị 120℃ (kachasị 150℃);

3. Gburugburu ultraviolet dị n'èzí ma ọ bụ nke siri ike;

4. A chọrọ elu dị nro nke ukwuu iji gbochie ihe ndị na-adịghị amịkọrọ;

A na-atụ aro ka ịhọrọ mkpuchi epoxy n'ọnọdụ ndị a:

1. Gburugburu ebe obibi na-anọpụ iche ma ọ bụ nke na-adịghị emebi emebi, okpomọkụ dị n'okpuru 120°C;

2. Oge owuwu ahụ dị mkpụmkpụ ma chọọ ndozi ngwa ngwa;

3. Njikwa ọnụ ahịa siri ike.
