Otu esi ahọrọ ihe mgbakwunye na resin polyurethane nke mmiri

Kedu otu esi ahọrọ mgbakwunye na polyurethane nke mmiri? E nwere ọtụtụ ụdị ihe enyemaka polyurethane nke mmiri na-adabere na ya, na ntinye ngwa ahụ dị obosara, mana usoro nke inyeaka na-adabere na ya mgbe niile.

Nkwekọrịta nke mgbakwunye na ngwaahịa bụkwa ihe mbụ a ga-atụle na nhọrọ nke mgbakwunye. N'okpuru ọnọdụ nkịtị, a na-achọ enyemaka na ihe ahụ ka ọ dakọtara (yiri na nhazi) ma kwụsie ike (ọ dịghị ọgbọ ọhụrụ) n'ime ihe ahụ, ma ọ bụghị ya, ọ na-esiri ike ịrụ ọrụ nke inyeaka.

Ihe mgbakwunye na ihe mgbakwunye ahụ aghaghị ịnọgide na-arụ ọrụ mbụ nke ihe mgbakwunye ahụ ruo ogologo oge na-enweghị mgbanwe, na ike nke mgbakwunye iji nọgide na-arụ ọrụ mbụ na gburugburu ngwa ngwa a na-akpọ ịdịte aka nke mgbakwunye. Enwere ụzọ atọ ndị inyeaka ga-esi tụfuo ihe mbụ ha: volatilization ( arọ molecular ), mmịpụta (solubility nke mgbasa ozi dị iche iche), na Mbugharị (slubility nke polymers dị iche iche). N'otu oge ahụ, ihe mgbakwunye kwesịrị inwe nguzogide mmiri, nguzogide mmanụ na ihe mgbaze.

Iji nweta nsonaazụ ka mma, ngwa mgbakwunye na-abụkarị agwakọta. Mgbe ị na-ahọrọ nchikota, enwere ọnọdụ abụọ: otu bụ ngwa nchikota iji nweta nsonaazụ dị mma, nke ọzọ bụ maka ebumnuche dị iche iche, dị ka ọ bụghị naanị ọkwa kamakwa defoaming, ọ bụghị naanị ịgbakwunye ìhè kamakwa antistatic. Nke a bụ iji tụlee: n'otu ihe ahụ ga-emepụta synergies n'etiti ihe mgbakwunye (mkpokọta mmetụta dị ukwuu karịa nchikota nke mmetụta nke otu ojiji), mmetụta mgbakwunye (mkpokọta mmetụta bụ nhata na nchikota nke mmetụta nke otu ojiji) na mmetụta mmegide (mkpokọta mmetụta bụ ihe na-erughị nchikota nke mmetụta nke otu ojiji), ya mere, oge kacha mma na-emepụta synergies, iji zere mmegide mmetụta.

 

N'ime usoro mmepụta nke polyurethane nke mmiri na-eme ka ọ gbakwunye otu ụdị ihe mgbakwunye, ọ dị mkpa ịṅa ntị na ọrụ ya na ọkwa dị iche iche nke nchekwa, ihe owuwu, ngwa, ma tụlee ma nyochaa ọrụ ya na mmetụta ya na ngalaba na-esote. 

Dịka ọmụmaatụ, mgbe a na-eji agba polyurethane nke mmiri na-arụ ọrụ na-arụ ọrụ na-eme ka mmiri na-ekpo ọkụ na-agbasasị, ọ na-arụ ọrụ ụfọdụ na nchekwa na iwu ụlọ, ọ dịkwa mma maka agba nke ihe nkiri agba. A na-enwekarị mmetụta na-achịkwa, ma n'otu oge ahụ na-akpata usoro mmetụta dị mma n'otu oge, dị ka iji silicon dioxide, e nwere mmetụta nkwụsịtụ, na ntinye mmiri, mgbochi mgbochi elu na mmetụta ndị ọzọ dị mma.

Tụkwasị na nke ahụ, n'iji otu onye na-eme ihe nwere ike inwe mmetụta na-adịghị mma, dị ka mgbakwunye nke silicon-nwere onye na-eme ihe na-eme ka ọ bụrụ ihe na-adịghị mma, mmetụta ya na-eme ka ọ bụrụ ihe dị ịrịba ama, nwere ike nweta mmetụta dị mma nke ọma, ma iji nyochaa ma enwere oghere shrinkage. , abụghị urukpuru, adịghị emetụta recoating na na. N'ihe niile, ntinye nke mgbakwunye bụ, na nyocha ikpeazụ, usoro bara uru, na naanị ihe nyocha maka nyocha kwesịrị ịbụ àgwà nke nsonaazụ ngwa ahụ.
