mfundo za chisamaliro ndi kuyeretsa pamalo yokutidwa ndi utoto madzi kupezeka

utoto aliyense lalabala - ndimakina; Luso makhalidwe a inki silingakhoze kokha mosavuta ndipo mwamsanga ntchito zinthu pa pamwamba ofukula kapena yopingasa wa wodzigudubuza ndi burashi, koma kenako kwa nthawi yaitali misozi pamwamba ndi nsalu yonyowa pokonza.

Kutisambitsa zida nyumba ndi zovala kuchokera utoto amenewa amagwiritsidwanso ntchito lather (chifukwa suspensions polyvinyl nthochi); akiliriki emulsion utoto uyenera uyambe kuwawa spatula - liwiro kuchotsa chachikulu cha m'dera Napempha kwa pamwamba utoto, choyamba kumata ndi pepala kapena mapepala, kuika iwo pa wowuma gelatinous kapena wamba mapepala khoma phala.

Kuyeretsa mbali ya padziko akiliriki mwina ntchito yomanga choumitsira ndi spatula - moto makombo a padziko ndi kuchotsa tsamba awo.

solvents mankhwala komanso ali oyenera kuchotsa utoto madzi ofotokoza ndi kupereka pang'onopang'ono mavuto aakulu, koma iwo zimatulutsa fungo zosasangalatsa ndi poizoni kwa chamoyo.

Angapo malangizo pa ntchito utoto otsegula

Pamaso ntchito ndi madzi ofotokoza zofuna utoto kuti limagwirizana, pulasitala, ndipo ngati n'koyenera zashpatlevat pamalo onse. Ngakhale utoto zachilengedwe, inu kuphika chifukwa Goggles, ndi fumbi chigoba ndi magolovesi.

Kujambula Bank ndi kugwedezeka, nkhani wosakaniza ndi kuchepetsedwa ndi madzi malinga ndi malangizo. Pa khoma zashpatlovannye Utoto ntchito zigawo zitatu pa mapepala khoma la - wina. Utoto ntchito n'kupanga kufanana kwa zenera ku khoma. The zida ntchito kugwiritsa ntchito burashi, odzigudubuza, opopera ndi spatulas.
