Ngaba kuyimfuneko ukwenza unyango lwe-anti-alkali primer ngaphambi kokutshiza ipeyinti yelitye lokwenyani?

1. Yintoni ipeyinti yamatye yokwenene?

Ipeyinti yamatye yangempela yipeyinti ekhethekileyo eyenza i-texture efana ne-marble, granite, iinkozo zokhuni kunye nezinye izinto zamatye phezu kwezakhiwo.Ifanelekile ukupeyinta iindonga zangaphakathi nangaphandle, iisilingi, imigangatho kunye nezinye iindawo zokuhombisa.Amacandelo aphambili epeyinti yamatye yangempela i-resin, i-pigments kunye nezizaliso.Ubomi bayo benkonzo kunye nokusebenza kuxhomekeke kumgangatho kunye nokuzinza kwendawo yepeyinti.

2. Kutheni kuyimfuneko ukwenza unyango lwe-primer-resistant alkali?

Ukwakhiwa kwepeyinti yamatye yangempela kufuna ukusetyenziswa kwe-primer enganyangekiyo ye-alkali yonyango olusisiseko.Oku kungenxa yokuba umphezulu wokwakha wenziwa ikakhulu ngezinto ezomeleleyo zealkaline ezifana nesamente nodaka.Umxholo we-calcium hydroxide kwi-samente uphezulu, kwaye ixabiso layo le-pH liphakathi kwe-10.5 kunye ne-13, eya kuchaphazela ukubunjwa kweekhemikhali zepeyinti yamatye yangempela.Ukuchaphazeleka kunokubangela iingxaki ezinjengokuqhekeka kunye nokuxobuka kwepeyinti.

I-Alkali-resistant primer iqulethe izongezo ezifana ne-polymer fatty amide, enokuthi idibanise kakuhle nesamente kunye nodaka.Kwakhona kwandisa ukuchasana kwepeyinti yamatye okwenene kwizinto ze-alkaline, ukuqinisekisa umgangatho kunye nokuzinza kwendawo yepeyinti.Ke ngoko, kubaluleke kakhulu ukwenza unyango lwe-alkali-resistant primer ngaphambi kokutshiza ipeyinti yelitye lokwenyani.

3. Indlela yokufaka i-primer-resistant alkali?

Xa usebenzisa i-primer-resistant primer, kufuneka uqale upholise umphezulu wesakhiwo ukuqinisekisa ukuba umphezulu ucocekile, ugudile, kwaye awunayo ioli, uthuli kunye nezinye izinto ezingcolileyo.Emva koko sebenzisa i-primer ekhethekileyo ye-alkali-resistant for priming ukuqinisekisa ukuba usetyenziso kunye nobukhulu obuhambelanayo.Emva kokuba unyango lwe-primer lugqityiwe, kufuneka lomiswe ngokupheleleyo kwaye luqiniswe ngaphambi kokutshiza ipeyinti yamatye yangempela.

4. Isishwankathelo

Ke ngoko, kubaluleke kakhulu ukwenza unyango lwe-alkali-resistant primer ngaphambi kokutshiza ipeyinti yelitye lokwenyani, enokuqinisekisa umgangatho kunye nokuzinza komphezulu wepeyinti, ukuthintela ukuqhekeka, ukuxobuka kunye nezinye iingxaki, kunye nokwandisa ubomi benkonzo kunye nobuhle belitye lokwenyani. ukupeyinta.
