Kusiyana pakati pa utoto ndi zokutira
Kusiyana pakati pa utoto ndi zokutira kwagona pakupanga ndi kugwiritsa ntchito kwake. Utoto ndi mtundu wa zokutira, koma si zokutira zonse ndi utoto.
Utoto ndi chisakanizo chamadzimadzi chomwe chimakhala ndi inki, zomangira, zosungunulira, ndi zowonjezera. Nkhumba zimapereka mtundu ndi opacity, omangira kugwira inki pamodzi ndi kumamatira pamwamba, zosungunulira kuthandiza ntchito ndi evaporation, ndi zina kumapangitsanso zinthu zosiyanasiyana monga kuyanika nthawi, durability, ndi kukana UV kuwala kapena mankhwala. Utoto umagwiritsidwa ntchito nthawi zambiri kukongoletsa ndi kuteteza pamwamba kuti zisachite dzimbiri, nyengo yanyengo, ndi kuvala.
Kuphimba, kumbali ina, ndi mawu otambalala omwe amaphatikiza mitundu yosiyanasiyana ya zida zomwe zimagwiritsidwa ntchito pamalo otetezedwa, kukongoletsa, kapena ntchito. Zopaka zingaphatikizepo utoto, ma varnish, lacquers, enamels, ndi mitundu ina ya mafilimu kapena zigawo. Mosiyana ndi utoto, zokutira zimatha kukhala zolimba, zamadzimadzi, kapena mpweya. Atha kugwiritsidwa ntchito popopera mankhwala, kupukuta, kugudubuza, kapena kuviika, kutengera mtundu ndi zofunikira za ntchito.
Mwachidule, utoto ndi mtundu wina wa zokutira zomwe zimakhala ndi pigment, binders, solvents, ndi zowonjezera. Amagwiritsidwa ntchito makamaka pofuna kukongoletsa ndi kuteteza pamwamba. Kuphimba, kumbali ina, ndi mawu otambalala omwe amaphatikiza mitundu yosiyanasiyana ya zida zomwe zimagwiritsidwa ntchito pamalo otetezedwa, kukongoletsa, kapena ntchito.
Kusiyana pakati pa utoto ndi utoto wa latex
Kusiyana kwakukulu pakati pa awiriwa kumakhala mu ntchito zawo, kuphatikizapo zipangizo zosiyanasiyana. Zopangira zazikulu za utoto wa latex ndi acrylic emulsion, yomwe ndi zinthu zochokera m'madzi. Utoto umapangidwa kuchokera ku natural resins ndi chinthu chopangidwa ndi mafuta.
Kuchuluka kwa ntchito ziwirizi ndi zosiyana. Utoto wa latex ndi jiniralamagwiritsidwa ntchito popenta makoma, ndipo amagwiritsa ntchito madzi ngati sing'anga. Pambuyo pomanga, vuto la kuipitsidwa kwa chilengedwe ndilochepa kwenikweni.
Ngati mumasankha utoto, kuchuluka kwake kwa ntchito ndikokulirapo. Sizingagwiritsidwe ntchito pojambula makoma, komanso mipando ndi matabwa. Mtundu wake ndi wokulirapo. Komabe, sizingakwaniritse zofunikira zoteteza chilengedwe ndipo zimatha kutulutsa mpweya woipa monga benzene. ”
