Kulula kakhulu ukudideka ezinhlobonhlobo zempahla emakethe yokuqedela indlu, bonke abathengisi bengazi ukuthi kukhona amapende abo angaphakathi. Kodwa-ke kuvela ukuthi azihambisani ngokuphelele nemingcele ebhaliwe, impango emanzini noma ube nephunga elingenakuxolisa. Ngakho-ke, lapha sibheka izinhlobo ezisetshenziswa kakhulu kunazo zonke zokudayisa ngenhloso yokuhlobisa ingaphakathi, ukuze umthengi alahleke esitolo lapho ethenga imikhiqizo efanele ngesikhathi sokulungisa amakhaya amaningi.
Kungani ukudweba kuhlukaniswe izinhlobo ezahlukene?
Uma sisebenzisa ukubunjwa kombala esiqongweni, sithola ifilimu ye-thinnest equkethe izingxenye ezintathu. Zithinta kakhulu izici ezibaluleke kakhulu zokupenda kwangaphakathi. Impahla yokuqala yilabo abathintekayo abaphuma ngokushesha ngemva kokufaka lokho okushiwo phansi, ifenisha noma izindonga. Isici sesibili yi-pigment ephethe umbala. Ingxenye yesithathu, ehlale ikhona emidwebeni, iyisivinini esivumela ukuthi izinhlayiya ezinhle ze-pigment zikwazi ukunamathela phezulu. Kulesi sibuyekezo, sizohlukanisa upende zibe yizinhlobo kuye ngokuthi yi-substrate.
Izinhlobo zokupenda kwangaphakathi:
- Ukupenda kwamafutha.
- Ipende elisekelwe emanzini elisekelwe ku-PVA.
- Amapayipi ase-Acrylic amanzi asekelwe.
- I-Alkyd Enamel.
- I-Latex ipeyinti.
Imikhiqizo enjalo ikhiqizwa ngesisekelo sokomisa amafutha, uma ingenakho ukuncintisana futhi yayithandwa kakhulu. Umdwebo usomile kakhulu, umbobo "awuphefumuli" futhi isikhathi eside unikeza iphunga elimnandi. Kudingeka ukuhlanza kokuqala kokuqala, ngaphandle kwalokho ifilimu enhle etholakalayo iyovuvukala. Izindleko zezingoma zamafutha ziyakhanga kakhulu. Ngaphezu kwalokho, ukubunjwa kwamafutha okuphephile kuphephile empilweni, kube nokusetshenziswa okuphansi, bangene ngaphakathi enkuni futhi banomthelela omkhulu emakhemikhali.
Isisekelo sawo wonke amakhemikhali ahlakazekile ngamanzi ajwayelekile, okwenza akhangele ekuqedeni isakhiwo sokuhlala. Ukubunjwa kwe-polyvinyl acetate yizinto ezihlukahlukene ezishibhile. Kukhona, kokubili ukudweba kwamanzi okugcoba emanzini futhi okucwebezelayo. Sebenzisa le mikhiqizo engabizi futhi ephezulu kakhulu yokwelapha izindonga ezenziwe nge-plasterboard kanye nezakhiwo zamapulangwe, ama-plasters, izinto ezivuthayo.
Akunconywa ukuthi upende le mikhiqizo ngemikhiqizo yensimbi kanye neziqhafaza ezicwebezelayo. Ukwehluleka kwesibili kwaleli peyinti langaphakathi kungukungaqiniseki kwamanzi, ngenxa yalokhu kunconywa ukuba kusetshenziselwe ukwelashwa kwezindonga kanye nokufakwa ngaphandle kwamakamelo owomile kuphela.
Amanzi abuye ahlanzeke, kepha amapolycrylates (ama-polymers of methyl, e-ethyl kanye nama-acrylates) abumba i-film-forming substance. Amakhemikhali amasha kulula ukususa, kodwa ngemva kokomisa, isendlalelo sokuhlobisa asesabi ukuhlanza okumanzi. Noma kunjalo, siyaqaphela ukuthi ezindlini zangasese nasemakhishini kufanelekile ukufuna ezinye imibala enokwethenjelwa.
Ekukhiqizeni lezo zinhlanganisela, ama-alkyd varnishes ezinhlobo ezimbili asetshenziselwa: i-glyptal ne-pentaphthalic, futhi i-solvent ephilayo. Le ngxube ikuvumela ukuba ulandele umdwebo wokugqoka ohlala njalo futhi omuhle, kunconywa ukuba usebenzise, kokubili imisebenzi yangaphakathi nasemgwaqweni. Ipeyinti elingaphakathi elingu-alkyd elingaphakathi alinayo i-precipitation, ayigqoki, kuvamile
Izingoma ze-latex zanamuhla zihlukile. Kunamapayipi e-latex okusabalalisa amanzi namapayipi ase-acrylic-latex amanzi-dispersion. Ama-Acrylate materials ayabiza kakhulu, kepha ngaphezulu kunokwakheka, upende olunjalo lwangaphakathi lungcono kakhulu kumaikhikhini, ukucubungula izindonga nokufakwe emgodini noma ezindlini zangasese.
