Ukudweba kwamanzi-emulsion: izici zobuchwepheshe, abakhiqizi, ukwakheka

Imidwebo yezimboni nezokudweba izindonga, ukufakelwa, phansi kwegumbi, ifenisha kuwo, kanye nefasitela nezakhiwo zomnyango, upende olusekelwe emulsion e-aqueous isetshenziswa njalo. Ipeyinti elisekelwe emanzini, izici zalo zobuciko ezihlinzeka ngezingubo ezizinzile neziphezulu, zinemvelo kakhulu futhi ayinayo umphumela onobuthi eziphilayo.

Izimiso zokwakheka komzimba wokuvikela odweba amanzi

Igama lomdwebo wamanzi-based (ukuhlakazeka kwamanzi) kungenxa yokutholakala kwesisekelo sawo sokumiswa kwezingulube, okuyinto ndawonye eyakha i-emulsion. Izakhi ezihlakaziwe azixubaniswanga ne-medium aqueous, kodwa zidalwa futhi zikhona nayo ngokufana.

Ngakho-ke, upende oluncike emanzini luqukethe i-filler, i-thickener, i-latex kanye ne-antiseptic.

Izinhlayiya ze-polymeri emva kokumiswa kwamanzi ebusweni zakha ungqimba olunamatshe. Umdwebo omisiwe ususwe kalula ngesandla, futhi isendlalelo asinakho iphunga elimnandi. Umdwebo awunamathele ekucindezelekeni komshini, kodwa awusetshenzisiwe ezindaweni ezenziwe ngensimbi ukugwema ukubola ngenxa yobuningi obuningi.

Izici eziyinhloko zobuchwepheshe bepende elisekelwe ngamanzi

Ipeyinti elisekelwe emanzini, izici zalo zobuciko - i-viscosity, izinga lokugeleza, ukuvuthwa okujulile kanye nesikhathi sokumisa, kube nemingcele yokukhiqiza eqinile, ikulungele kahle ukwelashwa kwendawo yangaphakathi yokuhlala.

Izinga lokuhlenga ubukhulu bembala ngamanzi kuboniswa ngumbhalo we-viscosity olinganiselwe ne-viscometer.

Ukusetshenziswa kwe-emulsion ukudweba ngokuqondile kuxhomeke ekutheni umthamo wokumunca wendawo owemukelayo futhi uvela kumamitha ayizigidi eziyi-100 kuya kwezingu-200 kumitha yendawo engaphezulu, odwetshiwe ngendwangu yokudweba i-millimeter ebanzi.

Ubukhulu obuningi bokudweba ngamanzi buba ngu-1.3 kilogremu ngelitha ngalinye.

Isikhathi sokumisa kwepeyinti elisekelwe emanzini kuncike ekutheni umswakama kanye nokushisa kwe-air kanye nemitha kusukela emahoreni amabili kuya ngosuku. Izimo ezomile zokumisa zibhekwa njenge-+20 degrees Celsius no-65% umswakama.

Usuku lokuphelelwa yisikhathi lokupenda kwe- emulsion luxhomeke kakhulu ezimweni zokugcina (mhlawumbe - indawo emnyama epholile) futhi kuphakathi kwezinyanga ezingu-24.

Izitayela zokupenda kwamanzi zibonakala ngokugcwele ku-GOST 28196-89 idatha.

Izici zobuchwepheshe ngokusho kwe-GOST

Ipeyinti elisekelwe ngamanzi, izici zezobuchwepheshe (GOST) zazo ezibhaliswe ngaphansi kwenombolo 28196-89, kuthiwa kulo ipende lokuhlakazeka kwamanzi, elimelelwe ukumiswa kwezingulube kanye nokugcwalisa, okufakwe ekuhlakazeni okunamandla kwamapulisi okufakelwa, lapho izinto ezinokusiza ezihlukahlukene ezifana ne-emulsifier, i-stabilizer kanye Okunye.

I-GOST 28196-89 ishintshiwe i-GOST 19214-80 engasebenzi, i-GOST 20833-75, ngo-6-10-1260-87, ngo-6-10-2031-85, ngo-6-10-2054-86, ngo-6-10-2081 -86, ngokuphathelene nopende kanye nezinto zokugqoka. Wonke amapayipi okusabalalisa amanzi aphephile ngomlilo, futhi ukukhiqizwa nokusebenza kwazo kungenzeka kuphela emakamelweni anikezwa umoya.

Ngokusho kwe-GOST, ukuhamba nokugcinwa kwazo kufanele kwenziwe ezinkantini ezivaliwe ezingeni lokushisa elingaphezu kwama-degree angu-0, kodwa ukuncishiswa kwezinga eliphansi lokushisa kwama-degrees -40 ngaphakathi kwenyanga eyodwa kuvunyelwe.

Umdwebo we-emulsion wamanzi, izici zakhe zobuciko ezihlinzeka ngezakhiwo zayo zokukhanya, zihamba ngokuzimisela kokukhanya okulula efektri - isigaba sokuhlola sibekwe ngaphansi kwesibani esikhethekile samahora angu-24, bese kuthi amahora angu-2 ubumnyama obuphelele, bese kuqhathaniswa namasampuli ochwepheshe.

Izici zokusetshenziswa kwepende lokusabalalisa kwamanzi i-VEAC

Ipeyinti elisekelwe emanzini i-VEAK, izici zobuchwepheshe okuyizona ezidingeka kakhulu emsebenzini ophephile futhi ophuthumayo endaweni yezindlu zokuhlala, kulungiswe kahle ukulungiswa kwendlu.

Unombala omhlophe nesethi yezingulube ezengeziwe, ongathola nayo umbala oyifunayo.

Esikhathini ngasinye, izindawo ezizobe zidwetshwe kufanele zibusheleleke futhi zome - ezimweni ezinjalo, ukusetshenziswa kwe-VACC kuyoba ngaphansi kuka-150 amagremu kumitha yendawo ngayinye. Kuhle kakhulu ukulala phansi ezindaweni ezidala futhi ezenziwe ngopende, ngoba unesisekelo se-latex futhi umile phakathi kwamahora amane.

Njengoba i-WEAK iyi-paint acrylic esekelwe ngamanzi, izici zobuchwepheshe zivumela ukuba zihlanjululwe ngamanzi, kodwa hhayi ezingamaphesenti angama-10 omqulu wesisekelo. Ungasebenzisi i-diluents yamakhemikhali. Izakhiwo zepende zenza kube lula ukugeza izindawo ezidwetshwe ngamanzi afudumele, kodwa amathuluzi kufanele ahlanzwe ngokushesha ngemva kokuba umsebenzi usuqedile.

Ngaphansi kwezimo ezifanele, ubuso obunziwe abukhiphi umbala namandla amakhulu iminyaka engu-7.

Izici zokusetshenziswa kwepeyinti ye-polyvinyl acetate

Ngokufanayo ngekhwalithi nokuhamba kwesikhathi, kanye nenqubo yesicelo yi-polyvinyl acetate yamaphesenti aphethwe ngamanzi, izici zobuchwepheshe ezivumela ukuba zisetshenziswe ekudwebeni hhayi kuphela izakhiwo zangaphakathi zesakhiwo, kodwa futhi namakhadibhodi, i-plywood, i-drywall kanye nezinkuni.

Ipeyinti ye-polyvinyl acetate ayinamandla, kodwa wesaba ngokweqile ukushisa kwezinga lokushisa kanye nomswakama ophezulu. Le peyinti i-emulsion yamanzi, izici zobuchwepheshe ezivumela ukuba zisetshenziswe ekuqedeni ubuso, futhi ngenxa yokuthi zimile ngokuphelele emahoreni amabili.

Ukusetshenziswa kwepeysi ye-polyvinyl acetate emulsion ingamamitha ayizigidi ezingu-200 ngomitha wesikwele, kubalulekile ukuyibeka ngaphezu kwezigaba eziningana ukuze upende amabala. Ukusetshenziswa okuphezulu kanye nokwakhiwa okuqondile kwenza kube kubi kakhulu uma kuqhathaniswa nezinye izinhlobo zamapende .

Izici ezicacile zokupenda kwamanzi "Tex"

Uma ukhetha uhlobo oluqinile lomdwebo nomkhiqizo we-varnish, kufanele futhi uqaphele upende oluthiwa "Tex". Kuyinto eyisisekelo se-acrylate ye-silicone-modified base-modified, ekhonjiswe nge-gloss white, ukugeleza okulinganiselayo nokulula kwesicelo. Kuyo, uhla olugcwele lwemibala luyakhiqizwa.

Ipeyinti elisekelwe emanzini "Tex", izici zobuchwepheshe ezivumela ukuba zisetshenziswe kubitini, ukhonkolo, izakhiwo zokhuni, ezisetshenziselwa ukwelashwa kwezindonga nokufakwa; Yenza ifilimu i-film ephathekayo evumela ukuthi umoya ujikeleze ngokukhululekile phakathi kobuningi bepende kanye nezinto ezibonakalayo. Kodwa-ke, ukuguqulwa okuyinhloko nokusobala kwe-Tex ukudweba ukuzwela ukushisa kwalo - umoya ekamelweni lapho usebenzisa kufanele kufudumele kunama-degrees Celsius +.

Izimiso ezijwayelekile zokunakekelwa nokuhlanzwa kwezindawo ezimbozwe ngopende lokusabalalisa kwamanzi

Noma yimuphi upende olususelwa emanzini lungasetshenziswa; Izici zobuchwepheshe bale peyinti akuvumeleki kalula futhi ngokushesha zisebenzise lezinto ezibonakalayo endaweni eqondile noma enezingqimba nge-roller ne-brush, kodwa futhi ngemva kwesikhathi eside usula le ndawo ngenhla emanzi.

Ukuhlanza amathuluzi wokwakha kanye nezingubo ezivela kuleso sende, isobho le-soap (for suspension polyethyl acetate) lisetshenziselwa; I-emulsion ye-Acrylic ipende kufanele ilahleke okokuqala nge-spatula - ukuze isivinini esikhulu sokususwa, indawo efunwa yendawo edwetshiwe kuqala iphepheni ngamaphepha noma amaphephandaba, ukutshala ngesitashi se-gelatin noma i-wallpaper ejwayelekile yeglue.

Kungenzeka ukuhlanza izindawo ezibonakalayo kusuka ekupendekeni kwe-acrylic ngokusebenzisa isomisi sezinwele zokwakha kanye ne-spatula - ngokushisa izingcezu zomzimba bese ubasusa nge-blade.

Amakhemikhali amakhemikhali nawo afanelekile ukususa amapayipi asekelwe emanzini, ngenhloso yokulimaza kancane kancane, kodwa akhiqiza iphunga elimnandi futhi ayinobuthi emzimbeni.

Ezinye izincomo ekusetshenzisweni kwamapayipi okusabalalisa amanzi

Ngaphambi kokusebenza ngepende elisekelwe emanzini, kufanele uvumelanise, uphahla futhi, uma kunesidingo, usebenzise zonke izindawo. Naphezu kokuhambisana kwemvelo yopende, usadinga ukulungisa izibuko zokuzivikela, umshini wokuphefumula namagilavu omsebenzi.

Ikhono lokudweba lingagungqiswa, okuqukethwe kwalo kuhlanganiswe futhi kuhlanjululwe ngamanzi ngokusho kwemiyalelo. Ezindongeni ezidwetshiwe, upende usetshenziswe emigqeni emithathu, ephepheni - kwelinye. Ukudweba kusetshenziswe emaphethini afanayo ukusuka efasiteleni kuya odongeni. Ama-Brushes, ama-rollers, ama-spatula nama-spray izibhamu asetshenziswa njengamathuluzi wesicelo.
