Mmanụ mkpuchi varnish, nke a makwaara dị ka agba mkpuchi ma ọ bụ varnish, na-arụ ọrụ na mkpuchi, iguzogide mmiri, mwepụ okpomọkụ, na ịgwọ na transformers ugboro ugboro.
Dịka ihe mejupụtara kemịkalụ dị iche iche ha si dị, enwere ike kewaa mmanụ mkpuchi ugbu a n'ụdị atọ: dabere na polyester; klas Resin; ihe ndị na-eme ka ihe dị n'ime siliceous. A na-akwadebe mmanụ mkpuchi polyester site na mmeghachi omume condensation nke polyols na polyacids, ọ na-abụkarị mmiri na-enweghị agba ma ọ bụ odo odo na-acha odo odo.

Agbanyeghị, mmanụ mkpuchi polyester nwere oke viscosity, okpomọkụ na-emetụtakwa viscosity ya nke ukwuu. viscosity na-abawanye nke ukwuu na obere okpomọkụ, nke na-emetụta nke ukwuu mmetụta mmiri mmiri ya na okpomọkụ ya. Ya mere, mgbe ejiri ya, ọ na-adịkarị mkpa ịgbakwunye ihe ndị na-agbaze iji belata viscosity nke mmanụ mkpuchi, ịnọgide na-enwe ezigbo mmiri mmiri, ma hụ na enwere ike mikpuo transformer ugboro ugboro kpamkpam n'oge mikpuo. Ike kpọmkwem nke mmanụ mkpuchi polyester na ihe na-agbaze bụ ihe dịka 0.9, nke enwere ike ịnwale site na mita ike ndọda kpọmkwem.
Nke abụọ, mmanụ mkpuchi polyester na-adịkarị mfe ịgbaze ma mebie n'oge okpomọkụ dị elu, na-emepụta ihe acidic na sludge, nke na-emetụta ọrụ nkịtị nke ngwaahịa ahụ ma na-egbochi oke ojiji ya na gburugburu okpomọkụ dị elu. Na mgbakwunye, ma e jiri ya tụnyere resin na mmanụ mkpuchi siliceous, mmanụ mkpuchi polyester nwere ụkpụrụ tangent dielectric dị elu karịa, nke pụtara na mfu ike dị ukwuu n'okpuru mpaghara eletrik na-agbanwe agbanwe ma ga-emetụta arụmọrụ ọrụ nke ngwaahịa ahụ ruo n'ókè ụfọdụ.
Ugbu a, a na-ejikarị mmanụ mkpuchi polyester eme ihe maka itinye ihe mkpuchi, dịka transformers ugboro ugboro, moto, waya, wdg, nke nwere ike ime ka mkpuchi dịkwuo mma, ike ọkụ, na iguzogide mmiri nke ngwaahịa ma gbasaa ndụ ọrụ ha. Mmanụ mkpuchi dabere na resin bụ ihe mejupụtara kemịkalụ polymer, nke na-adịkarị n'ụdị mmiri mmiri ma ọ bụ siri ike, yana ezigbo ike iyi.
Enwere ike ịmepụta mmanụ mkpuchi dabere na resin site na ịhazi oke nke ihe ndị e ji emepụta ihe na ọnọdụ mmeghachi omume iji mepụta mmiri resin nwere obere viscosity. Mmiri ndị a nwere ezigbo mmiri mmiri na ihe mkpuchi, ha anaghị achọkwa ihe mgbakwunye ọzọ. N'ọnọdụ okpomọkụ, mmanụ mkpuchi dabere na resin nwekwara ike ịdị nro ma ọ bụ gbazee. Ma e jiri ya tụnyere mmanụ mkpuchi polyester, mmanụ mkpuchi sitere na resin nwere nkwụsi ike dị elu, arụmọrụ mkpuchi eletriki ka mma, yana ọnụ ahịa dị elu. A na-ejikarị ya eme ihe maka mkpuchi nke ọtụtụ transformers, ọdụ eletriki, na njikọ. Mmanụ mkpuchi sitere na siliceous bụ ihe mejupụtara kemịkalụ silicon organic dị ka polydimethylsiloxane. Ọ na-abụkarị mmiri doro anya na-enweghị agba ma ọ bụ odo odo dị nro nke nwere obere viscosity na ezigbo fluidity.
Ma e jiri ya tụnyere mmanụ polyester na resin, mmanụ mkpuchi siliceous nwere obere uru ọnwụ dielectric, obere mfu ike n'okpuru ubi eletrik na-agbanwe agbanwe, yana arụmọrụ ọrụ dị elu nke ngwaahịa.
