Ukuze uphendule lo mbuzo, kuyadingeka ukuqonda umgomo wokwakheka kwefilimu le-LKM. Kuhlotshaniswa nezinqubo ezimbili eziningi eziningi - ukuvela kwengcindezelo yokucindezela kwangaphakathi ngesikhathi sokusebenza kwe-polymerization kanye nokunamathelisa. Amandla okunama-adhesion (adabukile) azama ukugcina ifilimu ebusweni besisekelo, kanye nezingcindezi zangaphakathi (SVN) zizophazamisa. Isici sokuqina singamandla efilimu (i-SPR).
Ukuze unqume ukuthi yiluphi upende ofaneleke kangcono ngale mbono, kuyadingeka ukuthola ngisho nasekuhlukanisweni kwe-LKM. Okokuqala, upende uhlukaniswe ngezinhlobo ze-solvent. Amapende kuma-solvents ezi-organic akhiwa aminyene, ngakho-ke ifilimu engaphezulu icishe ibe noma cha (ukukhishwa kusekelwe ku-resin ye-pliolite) futhi yenzelwe izindawo zensimbi nezensimbi.
Amapeni angenamanzi angenayo awalona iphunga, lome ngokushesha. Amandla "wokuphefumula" kwifilimu eyakhiwa yiwo makhulu impela, futhi ngenxa yalokho alungele izindawo ezinamaminerali. Izinto ezibophayo - enye ingxenye ebaluleke kakhulu ye-LKM. Yi-binder enikeza upende igama - uwoyela, alkyd, acrylic, njll.
Amapeni kawoyela mhlawumbe umbono oshibhile kakhulu we-LKM, lapho ukubopha okubophayo kusebenza khona. Izinto ezinjalo zakha ifilimu eminyene, ephefumula kabi "engenampilo, ngakho-ke zisetshenziselwa kakhulu umbala wesihlahla. Ngokuqondene no-Enamel, ngoba imisebenzi ye-Facade ilungele izinhlobo zazo ezimbili: Alkyd ne-polyurethane. I-Alkid Enamels yakha eminyene, eqinile, kunalokho ihlala isikhathi eside, kepha ifilimu elibuthakathaka. I-Polyurethane ilula kakhulu futhi ibushelelezi, kepha ngasikhathi sinye, ifilimu inamandla futhi imelana nokuqala nokushaqeka.
Khetha upende we-facade ulandela ezicini zezinto zokwakha
Izindonga zangaphandle ekhaya
Upende we-acrylic kwi-organic solvent, njengomthetho, yizingoma ze-matte ezisuselwa e-polycrrylate. Zisetshenziselwa ukupenda izindawo ezikhethiwe kanye nokhonkolo. Amapende ashukumi ancibilikayo ahlukaniswa kanjena: izingoma ezisuselwa ekusakazweni kwamanzi kwama-polymers ahlukahlukene namaminerali.
Amaminerali ajwayele ukusetshenziselwa indawo yamaminerali noma izisekelo ezazimbozwe ngaphambilini ngalezi zinto zokwakha. Amandla nokuqina kwezimbozo ezitholwe nazo ziphansi, ukusetshenziswa kwezinto ezinjalo zombala we-facades akudingeki.
Izinto zokuhlupheka zamanzi zitholakala ngesisekelo sezinhlobo ezine zokuhlakazwa: I-Polyvinyl Acetate (PVA), i-Styrere Buthadiene, acrylic, a aclicoone. Kulezi, izinhlobo ezimbili zokugcina zilungele ama-facade anemibala.
Upende osuselwa ku-acrylic disprings yindawo yonke. Ukuthola ukubheja okuphezulu kwekhwalithi ephezulu, kwanele ukufaka izingqimba ezimbili ebusweni. Ngasikhathi sinye, i-coating ayigcini nje ngokuthi "okuphefumula" kuphela, okwenza kube nokwenzeka ukusebenziseka ngempumelelo lezi zingoma kuma-facades amaminerali, kodwa futhi kunwebeka ngokwanele. Amapende we-Silicone-Emulsion afuywayo emanzini futhi ahlanganise izakhiwo ezinhle kakhulu zemidwebo ye-acrylic ne-silicate: cishe ziphakeme njengezisiling, futhi ngaphezu kwalokho akunamthelela ekuthuthukisweni kwama-microorganisms. Lezi zinto zokwenziwa zilungele cishe zonke izinhlobo zezinsika.
Futhi iqembu lokugcina - upende oguqulwe nge-silicone esisekelweni se-acrylic. Baphinde baqinisekisa ukunamathela okuhle nokuvikelwa okuhle emisebeni ye-UV. Ukomisa okunjalo komile ngamandla kagesi angaphansi komhlaba kunokuhlanganisa i-acrylic, ngakho-ke awazi ama-microcracks. Zingasetshenziswa cishe kubo bonke ekusebenzeni kwe-substrate.
Kusuka ekuhlangenwe nakho okusebenzayo
Ngaphambi kokuqala umbala we-mineral surface, kufanele kwenziwe uchungechunge lwezivivinyo:
Alinganise amandla omshini womhlaba. Uma iqala noma kuyo kunopende wakudala okhohlayo, udonga kufanele luhlanzwe, bese lumbozwa inhlabathi.
Thola ukumunca kwesisekelo, ukugoqa odongeni lwamanzi angama-50-100 ml. Uma uketshezi seludonswe ngokoqobo phambi kwamehlo, kusho. Ukuhlanyezwa kodonga kukhulu kakhulu, okuzovimbela ukuhamba okujwayelekile kwenqubo yokwakheka kwamafilimu. Ungalwa nalokhu ngosizo lwenhlabathi efanelekile.
Nquma ukuhambisana kwepende entsha endala. Inkinga ingavela uma udonga lusetshenziselwa ukuhlanganiswa ngamafutha noma olunye upende kuma-solvents, ngenxa yokuthi ukwakheka kwamanzi okuphakelayo kubi noma kungaweli ebusweni. Inketho enkulu kakhulu ukususa ungqimba wangaphambili, kepha inqubo enzima, futhi imvamisa abanikazi bezindlu zakudala baphoqelelwa kaninginingi ukusebenzisa upende ofanayo ku-facade njengoba bekumbozwe ngesinye isikhathi. Uma sikhuluma nge-facade yamaminerali, khona-ke hamba, ngokwesibonelo, ngokupenda okwengeziwe kwe-acrylical acrylic acrylic acrylic-water-water-ukupenda, kusenokwenzeka uma usebenzisa inhlabathi ekhethekile noma uthenge upende oklanyelwe ukufaka izimbotshana zamafutha adala.
Susa ubukhona bokubumba. Uma kutholwa, kungasuswa kusetshenziswa izixazululo ezikhethekile.
Nquma ukuba khona kosawoti we-calcium, kabi noma ongancibiliki ngokuphelele emanzini. Kufanele futhi zisuswe ebusweni bodonga ngaphambi kokusebenzisa inhlabathi kanye nopende olwengeziwe.
