Primer isithombe sangemuva

Kunamathiselwa lodonga izindonga iqala nge nokulungiselela surface. Ubunjwe izinyathelo ezilandelayo: uma kunesidingo (ubudala udonga) ukuqondanisa usimende ingxube, bula ke kusukela maholoholo priming Shpatlevanie (uma kudingeka ne igridi ukumaska for ukugcizelela ezengeziwe) e izingqimba ezimbili, ilungiswe ofakwe lokukhuhla (noma idayimane anezikhala) emva omiswe yayo, enamathela primer we putty (kusendlalelo ngasinye), kwaba ukuqala yomthofu wokumisa noma izinga stickers wallpaper slicing yamaphephadonga nesibonelo Ukukhetha.

Shpatlevanie - isinyathelo kudingekile ekulungiseleleni izindonga i papering. Ngenxa yalokhu, thina uphawu microcracks, ezingeni kwamanzi, okwenza kube bushelelezi. Shpatlevanie lwenziwa izingqimba eziningana (kuye ngokuthi isimo izindonga) nge ngibopha futhi priming ka shanela ngamunye. Ehlubula esetshenziswa lokukhuhla nosayizi okusanhlamvu 80-120. Hlola inqubo Kunconywa kokuqeda yamathebhu, onikeza okungcono umphumela. izindonga lemva ngaphansi lodonga kufanele kube ngcono, i-ohlabayo sangemuva.

Lapho belungela ukuya khona, sisebenzisa namabhantshi amabili - ku usimende putty.

Kwenziwa - a acrylic noma vodopolimernye pretreatment isixazululo anemibala kancane noma kucace uzilungiselele olunye ebusweni aliqede. Ziyakwazi isakhi esibalulekile inqubo yokudala surface entsha ubudala noma ukuvuselelwa. Kuye kwenziwa substrate yilezi:

- acrylic, isicelo ekwelapheni cishe zonke izinhlobo evele. Bahlangana izimfuno umthengi, akuzona iphunga anobuthi, omiswe ngokuphelele amahora amabili kuya kwamahlanu. Isetshenziswa njengesici primer sangemuva;

- alkyd, ngokuvamile esetshenziselwa isicelo zokhuni. Siyabonga kubo, ebusweni "ichichima" futhi isilungele kokuqeda. Omiswe - amahora ayishumi nanhlanu eziyishumi kuya;

- glyptal - ngamagumbi ezomile. isikhathi Omiswe - amahora amabili nane. Isetshenziswa Ezimweni eziningi, kuphela ungqimba ebusweni insimbi;

- phenol - esinemthombo Primary zibe yizinkuni nensimbi. Qedela omiswe amahora eyishumi kuya.

Primer sangemuva ngenxa izakhiwo esiyinhlanganisela:

• It kuvimbela ukwakheka microcracks phezu;
• kuqinisa isizinda;
• It lubopha evele ukungena nakwamanye amazwe futhi kwandisa ukumelana yabo ukuze umswakama;
• Kunciphisa izindonga amanzi ukumuncwa (kwenza ebusweni "wettable") okulungiselelwe papering;
• kuthuthukisa adhesion izakhiwo (ababambelela phezu contact ezishelelayo ezihlukahlukene izakhiwo);
• biocide primer sangemuva kuvimbela ukubonakala isikhunta nangesikhunta, aqede imiphumela emibi ebusweni ukusilaphazeka.

Priming kusiza isicelo umfaniswano ingcina futhi ukunciphisa ukugeleza yayo.

Kwakucatshangwa ukuthi kungenzeka ukuba ikhiphe ne primer ngaphansi iphepha lokunamathisela odongeni, kodwa ingozi delamination, flaking, isehlukaniso ikhule kakhulu, ngakho bekhohlisa umnotho yemali akusho bathethelele uqobo. Ukusebenzisa primer akudingekile esimweni kuphela uma ungqimba yesibili isetshenziswa ukuqedela ukugaya putty. Lapho esebenza 'inkinga evele "primer sangemuva akuvunyelwe edingekayo. Futhi kubalulekile ukusebenzisa, uma kwamanzi substrate alanele noma ukungena nakwamanye amazwe kakhulu, angcolile, uthuli, namabala (usebenzisa odongeni endala ngaphandle ukuqeqeshwa okukhethekile).

Primer isithombe sangemuva akhethiwe kuye ngokuthi uhlobo lodonga. Ngokwesibonelo, iphepha kanye polymeric lodonga kuhluke adhesion ezindongeni surface futhi uqaphe ukukhetha ukwakheka primer.

Ukulungiselela Uphahla lwangaphakathi for Umdwebo (owande kakhulu sekugcineni) kunzima futhi kukhathaza ezingaphezu kuka ngokucubungula izindonga ngaphansi lodonga. Isizathu siwukuthi upende akufihli ukungapheleli ezincane nokushiyeka komngane, kodwa kunalokho "avelele" kubo. Kunconywe emva ungqimba yamathebhu lokuqala (eshibhile) kubangele glue qualitative "Ubulembu" (ukuvimbela okuvela kuyo microcracks ngenxa umswakama, izinga lokushisa izinguquko), futhi ngesinye isendlalelo 2 putty.

ukunakwa Maximum kufanele kwenziwe isibaluli isicelo, yokuhlanza kanye priming ungqimba wokugcina, inikeza eliphezulu kokuqeda putty. Le ncwadi esetshenziselwa ophahleni kuyafana izindonga.

Ekulungiseleleni ophahleni efiselekayo ukusebenzisa ukukhanya ohlangothini kanye endaweni ngayo. Ngenxa yale njongo, obala encane noma evamile "ethwele". Kokuqondisa isikhathi ukukhanya ukuhlonza ukukhubazeka kungenzeka, ukuvikela zamehlo.
