Kumanga ndi kusungaanti-corrosion steel:

(1) Pamaso penti chitsulo pamwamba mankhwala Sa2.5 siteji, yomanga mosamalitsa oletsedwa m'madzi, fumbi, mafuta ndi burashi kuti kuonetsetsa khalidwe.

(2) ❖ kuyanika chiŵerengero: Gulu A mfundo (m'munsi), Gawo B (hardener) = 9kg utoto: 1kg choumitsa (kapena atolankhani Ine chomera anauza chiŵerengero cha zomangamanga).

(3) Njira zomanga zomanga ndi izi: Gulu A laloza kukamwa kwakukulu, lilowa nawo Gulu A gulu B kuyambira pachiyambi, yambitsani mofanana.Kukalamba kwa mphindi 30, ikhoza kuphimbidwa.

(4) Zofunikira zakuthupi izi ndi kugawa ndi kugwiritsa ntchito utoto pambuyo pa chiŵerengerocho zidzagwiritsidwa ntchito mkati mwa maola asanu ndi limodzi.Osamalizidwa ndi zinthu zomwe ziyenera kusindikizidwa.

(5) Masiku amvula kapena chinyezi choposa 75% chiyenera kusiya kumanga.Kwa tsamba lowononga kwambiri lazakanema, maburashi omwe akufunsidwa amakanema ambiri.

(6) Mankhwalawa ayenera kusungidwa pamalo ozizira owuma kuti ateteze kuwala kwa dzuwa, kupatukana ndi moto, kutali ndi kutentha.

(7) Nthawi yosungiramo miyezi khumi ndi iwiri pambuyo pa kutha kwa zizindikiro zaumisiri ziyenera kufufuzidwa, monga zofunikira za ndondomeko, mukhoza kupitiriza kugwiritsa ntchito.
