Umdwebo we-abicah. Izimpawu nezici zomsebenzi.

Umdwebo we-abicah usetshenziselwa ukugqoka izigqoko. Ihlanganisa ukuhlanganiswa okuphilayo kwezingulube nezithasiselo, i-abicucin resin. Le nhlanganisela ingasetshenziswa kokubili amabhizinisi namakhaya angasese. Isiza ukuthola ukubonakala okuhle . Umdwebo we-abicah uhlose ukuvikela amathonya angashintshayo kanye nokushisa, nokuvimbela ukungena komswakama ngokweqile, okugcina ekubhubhiseni izinto.

Lapho kusebenza khona

Ungapenda ubuso bekhonkrithi, i-asbestos-samente kanye nezinto zokwakha, ezimbozwe nge-plaster, amapayipi e-perchlorovinyl amacici, ukuxuba okuhlukahlukene kwemikhiqizo engenisiwe ehloswe ku-facade.

Izinto eziningi azikwazi ukumelana nomswakama. Amanzi kancane kancane ashisa isakhiwo namandla akhe, ukubola kuqala ukuvela. Ukushisa kwezinga lokushisa ngaphandle, ukuqhaqhaqhaza nokuqhwaza okuqhubekayo kubuye kuholele ekutheni lokho kudla kudliwa futhi kubhujiswe. Ngakho-ke, endaweni yokuqala kufanele ivikelwe emanzini okugcoba. Ipeyinti elenziwe ngamabhilidi iyoba yindlela enhle kakhulu kulezi zinhloso, engenawo amanzi, iphikisana nezinguquko ezinzima zokushisa. Yenziwe izitshalo zamakhemikhali, kunezinhlobo eziningi zemidwebo, ngakho wonke umuntu kukhona umthunzi ofanelekayo ongathanda ukuyibona futhi uzosondela kuso sonke isakhiwo - ungakhetha noma yikuphi.

Isicelo

Ngaphambi kokufaka umdwebo esakhiweni sesakhiwo, kubalulekile ukulungisa ngokucophelela indawo: ukuhlanza ukungcola, ngakho-ke, okungcono kakhulu nge-spatula yensimbi, ukukhipha noma yikuphi ukungalungi. Ngemuva kokufakwa kwesibhakabhaka, udinga ukuwushaya emoyeni, futhi uhlanzekile uhlanzekile. Ngandlela-thile, kulokho okushiwo, kukhona ukulandelana, ukuphazamiseka, imibimbi, izitshalo noma izindawo ezicacile zezikhanyiso kwezinye izindawo.

Kunomunye owodwa umthetho, umswakama wekhonkri akufanele ube ngaphezu kuka-8%. Faka isicelo sokudweba ngezendlalelo eziningana (ikakhulukazi 2 noma 3) ngebhashi, roller ne spray, ngayinye ngehora noma ezimbili umehluko. Isigqoko sokuqala somdwebo sihlanjululwa nge-xylene kuya kwe-viscosity yamasekhondi angu-40 kuya kwangu-50 (ngokusho kwe-VZ-4), futhi ngemva kokumiswa, upende usetshenzisiwe nge-viscosity ka-60 kuya ku-100. Umsebenzi usuqedile usebenzisa ibhulashi noma i-roller. Uma i-viscosity ingama-50-60 s, bese usebenzisa i-sprayer yepende.

Ingxube yenziwe ku-mixer. Okokuqala engeza upende, emva kwama-oligomers e-acrylate nama-fillers. Konke lokhu kuhlanganiswe ngehora lehora, khona-ke sithola ukwakheka okufanako, i-viscosity yayo engamasekhondi angu-14-16.

Izinzuzo

Namuhla, upende lwe-silicone we-facade ludinga kakhulu ngenxa yekhwalithi enhle kanye nenani elikhulu lama-pluses, uma kuqhathaniswa namanye amaxube. Ngaphezu kokuvikela ukwaziswa okugqoke, iyakwazi ukukhiqiza izakhiwo ezinhle.

• Isiza ukuthi izinto zikwazi ukumelana nokushisa okuphakeme noma okuphansi kakhulu, ukukhanyisa ukukhanya noma umswakama ophezulu.
• Iyakwazi ukumelana nesimo sezulu.
• Ukuqina okukhulu.
• Ukuphikisana ne-ultraviolet.
• Izinhlawulo eziphezulu ze-hydrophobic.
• Ukumisa okwesikhashana.
• Amandla ukweqa umphuzi wamanzi.
• Ukungafani kokusetshenziswa.
• Kunciphisa amathuba okushisa komlilo.
• Ipende elihle kunazo zonke libekiwe endaweni yokukhonkolo. Le koqweqwe lwawo luhlala isikhathi eside.

Izici zomsebenzi

Ukudweba okuyi-facial silicone kuyinto enobuthi, ngakho-ke, uma usebenza nayo, ukukhulumisana okuphepha kufanele kwenziwe ngaphambili. Ngaphansi kwezimo akufanele uphule imithetho yokusebenza nalesi sihloko. Uma kungenjalo, uma ungena emgodini wokuphefumula, ungalimala empilweni, futhi ukunganaki emsebenzini kuzothinta umphumela wonke.

Umehluko ovela kupeyinti evamile

Umehluko oyinhloko wukuthi ekubunjweni kwawo akuyona ingxube yekhabhoni njengokuvamile, kodwa ukushintshaniswa kwe-silicon nokuhlanganiswa kwe-oxygen. Njengoba kuyaziwa, ekwenzeni amakhemikhali amakhemikhali anjalo aphikisana kakhulu.

Ngakho-ke, akumangalisi ukuthi ukwakhiwa kwendlela yokukhetha i-pelicic paint, njengoba kuzohlala isikhathi eside kakhulu, kuzogcina ukubonakala okuhle kakhulu kwesakhiwo nokuyivikela.

Ukwakhiwa kwepaint

I-koqweqwe lwawo, okudalwe kusuka ezinsisekelo ezimbili (i-silicon nomoya), isuselwa ngokwezifiso. Ngakho-ke, sekuyisikhathi eside. Ekubunjweni kwayo kunezithasiselo ezithile ezisiza ukufeza umphumela omuhle wokulwa nokubola. Futhi, ukuze upende lome ngokushesha, izinhlayiya ze-acrylic kanye ne-ethyl cellulose zenezelwa kuso.

Amaqabunga e-carbide ayadingeka ukuze kuthuthukiswe amandla nokuqina futhi agweme ukulimala okungenzeka emvelweni, lapho upende olususelwe khona-silicone luvikela. Intengo izohluka kuye ngokuthi lezi zakhiwo, kanye nombala. Kodwa ngokwesilinganiso, izindleko eziseduze zizovela ku-ruble angu-120 kuya ku-300 ebhange ngalinye. Ukwehluleka kokushintsha kwezinga lokushisa kunciphisa izinkathazo ezikhethekile. Ngethonya lamakhemikhali anonya, i-epoxy iphikisana, izosiza ukubhekana nabo.

Ukumelana nokushisa

Ngezinye izikhathi kubalulekile ukudweba indaba, esetshenziselwa izinga lokushisa eliphakeme (ezingaphezu kuka-100 degrees). Isibonelo, izindawo zokucima umlilo, izitofu, izinguquko.

Manje, abakhiqizi banikeza izinhlobonhlobo zamaphoyinti abakwazi ukumelana nokushisa kusuka ku-150 kuya ku-200 C. Ngokuqondene nezinto ezijamelana namazinga aphezulu okushisa, imakethe yabo iyancipha kakhulu. Futhi kuphela upende olumelana nokushisa olwenziwe yi-organosilicon lungagxila ekushiseni okungaphezu kwama-200 ° C.
