1. Yintoni ipeyinti yelitye yokwenyani?
Ipeyinti yelitye lokwenyani yipeyinti ekhethekileyo edala ubume obufana nemarble, igranite, iinkozo zomthi kunye nezinye izinto zelitye kumphezulu wezakhiwo. Ifanelekile ukupeyinta iindonga zangaphakathi nezangaphandle, iisilingi, imigangatho kunye nezinye iindawo zokuhombisa. Izinto eziphambili zepeyinti yelitye lokwenyani yiresin, iipigment kunye nezinto zokuzalisa. Ubomi bayo benkonzo kunye nokusebenza kwayo kuxhomekeke kumgangatho kunye nokuzinza komphezulu wepeyinti.
2. Kutheni kuyimfuneko ukwenza unyango lwe-primer olumelana ne-alkali?
Ukwakhiwa kwepeyinti yelitye lokwenyani kufuna ukusetyenziswa kweprimer engamelani nealkali kunyango olusisiseko. Oku kungenxa yokuba umphezulu wesakhiwo wenziwe kakhulu zizinto ezinamandla zealkali ezifana nesamente kunye nodaka. Umxholo wecalcium hydroxide kwisamente uphezulu, kwaye ixabiso layo le-pH liphakathi kwe-10.5 kunye ne-13, nto leyo eya kuchaphazela ukwakheka kweekhemikhali kwepeyinti yelitye lokwenyani. Impembelelo inokubangela iingxaki ezifana nokuqhekeka kunye nokuxobuka kwepeyinti.
I-primer enganyangekiyo yi-alkali inezithako ezifana ne-polymer fatty amide, enokudibana kakuhle nesamente kunye nodaka. Ikwanyusa ukumelana kwepeyinti yelitye lokwenyani kwizinto ze-alkaline, iqinisekisa umgangatho kunye nokuzinza komphezulu wepeyinti. Ke ngoko, kuyimfuneko kakhulu ukwenza unyango lwe-primer enganyangekiyo yi-alkali ngaphambi kokutshiza ipeyinti yelitye lokwenyani.
3. Uyifaka njani iprimer engangenisi alkali?
Xa usebenzisa i-primer enganyangekiyo yi-alkali, kufuneka uqale upolish umphezulu wesakhiwo ukuqinisekisa ukuba umphezulu ucocekile, ugudile, kwaye awunayo ioyile, uthuli kunye nezinye izinto ezingcolileyo. Emva koko sebenzisa i-primer ekhethekileyo enganyangekiyo yi-alkali ukuqinisekisa ukusetyenziswa ngokulinganayo kunye nobukhulu obuhambelanayo. Emva kokuba unyango lwe-primer lugqityiwe, kufuneka lomiswe ngokupheleleyo kwaye liqine ngaphambi kokuba litshizwe ngepeyinti yokwenyani yamatye.
4. Isishwankathelo
Ngoko ke, kubaluleke kakhulu ukwenza unyango lwe-primer olumelana ne-alkali ngaphambi kokutshiza ipeyinti yokwenyani yamatye, enokuqinisekisa umgangatho kunye nozinzo lomphezulu wepeyinti, ukuthintela ukuqhekeka, ukuxobuka kunye nezinye iingxaki, kunye nokwandisa ubomi benkonzo kunye nobuhle bokupeyinta ilitye lokwenyani.
