Hey there, bannange abaagazi b'okusiiga! Nga omugabi w’ebirungo ebitereeza, ntera okubuuzibwa oba waliwo ebiziyiza ebisaanira ebizigo ebigumu ebingi -. Well, eky’okuddamu ekimpi kiri nti yee, naye ka tweyongere okubbira mu mulamwa guno.
Ebizigo ebigumu ebya waggulu - bifunye obuganzi bungi mu myaka egiyise. Ziwa ebirungi ebiwerako okusinga ebizigo eby’ekinnansi. Okusookera ddala, zirina ebirungo ebiwunya (VOC) ebitono ebifulumizibwa. Kino kikulu nnyo naddala olw’amateeka agafuga obutonde bw’ensi okweyongera okwetoloola ensi yonna. Abantu beeyongera okutegeera ku ngeri eddagala gye likwata ku butonde bw’ensi, era ebizigo ebikalu ebingi - ddaala mu kkubo ettuufu.
Naye ebizigo ebigumu ebya waggulu - nabyo bijja n’okusoomoozebwa kwabyo. Emu ku nsonga enkulu kwe kutuuka ku kumaliriza okulungi era nga kutuufu. Okuva ebizigo bino bwe biba n’ebikalu ebingi, bitera okuba ebinywevu. Obuziba buno obweyongera buyinza okuvaako obuzibu nga orange peel effect, brush marks, oba uneven drying. Wano aba leveling agents we bayingira.
Ebirungo ebitereeza (leveling agents) bye bikozesebwa mu kugatta ebiyamba okulongoosa entambula n’engeri y’okuleeta ebizigo. Zikola nga zikendeeza ku kusika kw’okungulu kw’ekizigo, ne kigisobozesa okusaasaana kyenkanyi ku substrate. Mu bizigo ebigumu ebya waggulu -, kino kikulu nnyo okutuuka ku kumaliriza okw’omutindo ogwa waggulu -.
Waliwo ebika bya leveling agents eby’enjawulo ebisangibwa ku katale. Ebimu byesigamiziddwa ku silikoni, ate ebirala byesigamiziddwa ku akiriiki oba fluorocarbon -. Buli kika kirina eby’obugagga byakyo eby’enjawulo n’ebirungi byakyo.
Ebirungo ebikola leveling ebisinziira ku silicone - byettanirwa nnyo. Zirina omulimu omulungi ennyo ogw’okungulu era zisobola okuwa - gloss finish eya waggulu. Era zirina eby’obugagga ebirungi eby’okuseerera n’okuziyiza -, ekitegeeza nti ebifo ebisiigiddwako tebitera kunywerera wamu. Wabula oluusi zisobola okuleeta obuzibu mu kuddamu okusiiga singa tezikozesebwa bulungi.
Acrylic - based leveling agents ze nkola endala. Zikwatagana nnyo n’enkola ez’enjawulo ez’okusiiga era okutwalira awamu zisinga kukuuma butonde. Zisobola okuwa eby’obugagga ebirungi eby’okutereeza n’okukulukuta, era nazo tezitera kuleeta buzibu ku ngulu.
Fluorocarbon - based leveling agents zimanyiddwa olw’ebintu byabwe eby’enjawulo ku ngulu. Zisobola okuwa obulungi ennyo okugoba amazzi n’amafuta, wamu n’eby’obugagga ebiziyiza - okuwandiika ebiwandiiko. Naye ebiseera ebisinga zibeera za bbeeyi okusinga ebika ebirala.
Nga olondawo ekirungo ekitereeza ku bizigo ebigumu ebingi -, waliwo ensonga eziwerako z’olina okulowoozaako. Okusookera ddala, olina okulowooza ku kukwatagana n’enkola y’okusiiga. Ekirungo ekitereeza kirina okusobola okusaanuuka oba okusaasaana obulungi mu kizigo awatali kuleeta kwawula kwa phase oba obuzibu obulala.
Era olina okulowooza ku ngeri y’okusiiga. Enkola ez’enjawulo ez’okusiiga, gamba ng’okufuuyira, okusiimuula oba okuyiringisiza, ziyinza okwetaagisa ebika by’ebirungo eby’enjawulo ebitereeza. Okugeza, okufuuyira kuyinza okwetaagisa ekirungo ekitereeza ekiyinza okukendeeza amangu ku kunyigirizibwa kungulu okuziyiza okukosebwa kw’ebikuta by’emicungwa.
Ensonga endala enkulu kwe kumaliriza kw’oyagala. Bw’oba oyagala - gloss finish eya waggulu, oyinza okwetaaga leveling agent ey’enjawulo okusinga bw’oba ogenda ku matte finish.
Ku kampuni yaffe, tulina ebirungo bingi ebikola leveling agents ebisaanira ebizigo ebigumu ebya waggulu -. Tukoze okunoonyereza n’okukulaakulanya kungi okulaba ng’ebintu byaffe bisobola okutuukiriza ebyetaago ebitongole ebya bakasitoma ab’enjawulo. Tugezesezza ebirungo byaffe ebitereeza mu nkola ez’enjawulo ezisiiga ebikalu ebinene -, era ebivuddemu bibadde bisuubiza ddala.
Omu ku bakasitoma baffe, abakola langi entono -, yali alina obuzibu n’okuleeta ebizigo byabwe eby’emmotoka ebigumu ebya waggulu -. Baali bafuna nnyo orange peel effect, nga kino kyali kikosa omutindo gw’ebintu byabwe. Oluvannyuma lw’okugezesa ebirungo ebiwerako eby’enjawulo ebiyitibwa levelling agents ku katale, byajja gye tuli. Twateesa ku kimu ku bikozesebwa byaffe eby’okuleeta ebyuma ebisinziira ku silikoni -, era oluvannyuma lw’okutereeza ebimu mu nsengeka, byasobola okutuuka ku kumaliriza okuweweevu era okutuufu. Bakasitoma baabwe baali basanyufu nnyo olw’omutindo gw’ebizigo ogwalongooseddwa, era okuva olwo babadde bakozesa ebintu byaffe.
Kati, bw’oba oyagala okumanya ebisingawo ku nkola ya ba agenti baffe aba levelling, osobola okukebera ku link eno:4-okugezesadfgsdfg. Kirina ebimu ku bivudde mu kukebera mu bujjuvu n’okunoonyereza ku mbeera eziyinza okukuwa endowooza ennungi ku ngeri ebintu byaffe gye bikolamu mu bizigo ebigumu ebingi -.
Mu kumaliriza, waliwo ddala ebirungo ebitereeza ebizigo ebigumu ebingi -. Ekikulu kwe kulonda ekituufu okusinziira ku byetaago byo ebitongole n’ebyetaago byo. Oba oli munene - scale coating manufacturer oba DIY omutono, okubeera ne leveling agent entuufu kiyinza okuleeta enjawulo nnene mu mutindo gw'ebizigo byo.
Bw’oba oli mu katale k’ebirungo ebitereeza ebizigo ebigumu ebingi -, tolwawo kutuuka. Tuli wano okukuyamba okufuna eky'okugonjoola ekisinga obulungi ku pulojekiti zo ez'okusiiga. Tusobola okukuwa samples okugezesa, era ttiimu yaffe ey’ekikugu bulijjo yeetegefu okukuwa amagezi n’obuwagizi. Ka tukolere wamu okukola ebizigo eby’omutindo ogwa waggulu -, ebiziyiza obutonde bw’ensi nga biriko eby’obugagga ebirungi ennyo eby’okuleeta.
