Enkola ya Prepolymer:
Enkola ya prepolymer foaming erimu okusooka okuteekateeka prepolymer okuva mu (ekitundu ekyeru) ne (ekitundu ekiddugavu). Olwo, amazzi, ekirungo ekiziyiza, ekirungo ekikola ku ttaka, n’ebirala ebigattibwa mu prepolymer ne bitabulwa wansi w’okutabula okw’amaanyi-okuleetera okufuumuuka. Oluvannyuma lw’okuwona, ekaddiwa ku bbugumu erigere.
Enkola ya Semi-Prepolymer:
Enkola ya semi-prepolymer foaming erimu okusooka okuteekateeka prepolymer okuva mu kitundu kya polyether polyol (ekitundu ekyeru) ne diisocyanate (ekitundu ekiddugavu). Olwo, ekitundu ekisigadde ekya polyether oba polyester polyol, diisocyanate, amazzi, catalyst, surfactant, n’ebirungo ebirala ebigattibwamu ne bitabulwa wansi w’okutabula okw’amaanyi-okuleetera okufuumuuka.
Omutendera gumu-Enkola y'okufuumuula:
Mu nkola eno, polyether oba polyester polyol (ekitundu ekyeru) ne polyisocyanate (ekitundu ekiddugavu), amazzi, catalyst, surfactant, foaming agent, n’ebirungo ebirala ebigattibwamu byongerwa mu mutendera gumu ne bitabulwa wansi w’okutabulwa okw’amaanyi-speed nga tebannaba foaming.
Enkola ya one-step foaming ye nkola esinga okukozesebwa. Enkola endala ye manual foaming, nga eno y’esinga okuba ennyangu. Pima bulungi ebigimusa byonna, biteeke mu kibbo, era amangu ago bitabule bulungi. Oluvannyuma omutabula guyiwe mu kibumbe oba mu kifo obuveera bwa foam we bwetaaga okujjula. Weetegereze: Bw’oba opimira, kakasa nti osseemu ekirungo kya polyisocyanate (ekitundu ekiddugavu).
Okutwalira awamu ekifuba kya polyurethane ekikaluba kifuumuulwa ku bbugumu erya bulijjo, era enkola y’okubumba nnyangu nnyo. Okusinziira ku ddaala ly’ebyuma mu kuzimba, kiyinza okwawulwamu okufuumuula mu ngalo n’okufuumuula mu byuma; okusinziira ku puleesa mu kiseera ky’okufuumuuka, esobola okwawulwamu okufuumuuka kwa puleesa eya waggulu-n’okufuumuuka kwa puleesa entono-; okusinziira ku nkola y’okubumba, esobola okwawulwamu okufuumuula okusuula n’okufuuyira okufuumuuka.
