Ngaba kunyanzelekile ukuba kuqhubeke unyango lwe-anti-alkali primer ngaphambi kokutshiza ilitye lokwenyani?

1. Yintoni ipeyinti yelitye lokwenyani?

Ipeyinti yelitye lokwenyani yipeyinti ekhethekileyo edala imibhalo efana nemarble, i-granite, iinkozo zenkuni kunye nezinye izinto zamatye phezu kwezakhiwo. Ilungele ukupeyinta iindonga zangaphakathi nangaphandle, iziqwenga, imigangatho kunye neminye imigangatho yokuhombisa. Izinto eziphambili zepeyinti yelitye yokwenyani yi-resin, ii-pigments kunye neefilimu. Inkonzo yayo yobomi kunye nokusebenza kwayo kuxhomekeke kumgangatho kunye nokuzinza komphezulu wepende.

2. Kutheni kuyimfuneko ukwenza unyango lwe-alkali-ukunyangwa?

Ukwakhiwa kwepeyinti yelitye lokwenyani kufuna ukusetyenziswa kwe-alkali-enganyangekiyo kunyango olusisiseko. Kungenxa yokuba umphezulu wokwakha owenziwe ikakhulu ngezinto ezinamandla ze-alkali ezifana nesamente kunye nodaka. Umxholo we-calcium hydroxide kwisamente uphumile, kwaye ixabiso le-pH liphakathi kwe-10.5 neli-13, eliza kuchaphazela ukwakhiwa kwamachiza okwenziwa ngamatye okwenyani. Impembelelo inokubangela iingxaki ezifana nokuqhekeka kwaye zenziwe ngepende.

I-Alkali-Ukunganyangeki iqulethe izithintelo ezinjengePolymer enamafutha atyebileyo, enokuphulukana nesamente kunye nodaka. Ikwandisa ukuxhathisa kwepeyinti yelitye lokwenyani kwizinto ze-alkaline, ukuqinisekisa umgangatho kunye nokuzinza komphezulu wepeyinti. Ke ngoko, kuyimfuneko kakhulu ukwenza unyango lwe-alkali-ukunyangwa kwe-alkali ngaphambi kokutshiza ilitye lokwenyani.

3. Ungayisebenzisa njani i-alkali-enganyangekiyo?

Xa isebenzisa i-alkali-enganyangekiyo, kuya kufuneka uqale i-Polilish umphezulu wesakhiwo ukuqinisekisa ukuba umphezulu ucocekile, ugudile, kwaye ungenasiphelo seoyile. Emva koko sebenzisa i-alkali ekhethekileyo ye-alkali yokuphucula ukuqinisekisa ukuba usetyenziso noluqinisiweyo olungaguqukiyo. Emva kokuba unyango lwe-primer lugqityiwe, kufuneka lomiswe ngokupheleleyo kwaye luqiniswe ngaphambi kokutshiza ilitye lokwenyani.

4. Isishwankathelo

Ke ngoko, kuyimfuneko ukuba benze unyango lwe-Alkali-ukunyangwa ngaphambi kokutshiza ilitye lokwenyani, elinokuqinisekisa ukuba umgangatho kunye nokuzinza kunye nokuzinza kunye nezinye iingxaki, kunye nokwandisa inkonzo yokupeyinta.
