Mmeghachi omume kemịkalụ bụ isi n'oge lamination enweghị mgbaze

Site na ọganihu teknụzụ na-aga n'ihu, ọtụtụ ndị na-emepụta ngwugwu na-agbanwe agbanwe na-anabata lamination na-enweghị mgbaze.

Uru nke lamination enweghị mgbaze bụ ngwa ngwa, mfe, nchekwa gburugburu ebe obibi, uru dị ọnụ ala karịa.

Ọ dị anyị ezigbo mkpa ịmata mmeghachi omume kemịkalụ bụ isi n'oge a na-eji lamination enweghị ihe mgbaze eme ihe maka mmepụta oke ka mma.

Akụkụ abụọihe na-anaghị agbaze agbazee ji polyurethane (PU) mee ya, isocyanate (-NCO) nke a na-akpọkarị A component jikọtara PU, na polyol (-OH) nke a na-akpọkarị B component jikọtara ya. Nkọwa nke mmeghachi omume biko lelee n'okpuru;

Mmeghachi omume mbụ dị n'etiti A na B, -NCO nwere kemịkalụ na-emeghachi omume na -OH, n'otu oge ahụ, n'ihi na mmiri nwekwara otu ọrụ -OH, mmiri ga-enwe mmeghachi omume kemịkalụ na ntọhapụ nke ihe mejupụtara A CO₂, Carbon dioxide. Na polyurea.

CO₂ nwere ike ibute nsogbu afụ ahụ, polyurea nwekwara ike ibute mkpuchi mgbochi okpomọkụ. E wezụga na iru mmiri dị elu nke ọma, mmiri ahụ ga-eri ọtụtụ ihe mejupụtara A. Ihe si na ya pụta bụ na gluu agaghị agwọ 100%, ike njikọ ahụ ga-ebelatakwa.

Na nchịkọta, anyị na-atụ aro na;

Nchekwa ihe nrapado kwesịrị ịdị n'ebe dị jụụ ma kpọọ nkụ, ebe mmiri na-agaghị eru ya ala.

Ụlọ ọrụ ahụ kwesịrị idobe iru mmiri n'etiti 30% na 70%, ma jiri AC chịkwaa uru iru mmiri.

N'elu bụ mmeghachi omume kemịkalụ bụ isi dị n'etiti ihe ndọda abụọ, mana ihe ndọda mono-component ga-adị iche kpamkpam, anyị ga-ewebata mmeghachi omume kemịkalụ mono component n'ọdịnihu.
