Kumasulidwa nthawi:2026-01-27
Utoto wolembera mumsewu umagwira ntchito yofunika kwambiri pachitetezo chapamsewu powongolera oyendetsa, oyendetsa njinga, ndi oyenda pansi. Ngakhale kuti zingawoneke zosavuta, kapangidwe kake kapangidwa mosamala kuti azitha kuwoneka bwino, kulimba, komanso momwe chilengedwe chimagwirira ntchito.
Pakatikati pake, utoto wolembera mumsewu umapangidwa ndi zigawo zinayi zazikulu: zomangira, ma pigment, zodzaza, ndi zowonjezera.
Zomangira zimagwira ntchito ngati "glue" yomwe imagwira utoto pamodzi ndikupangitsa kuti igwirizane ndi msewu. Zomangira wamba zimaphatikizapo utomoni wa acrylic, alkyd resins, ndi epoxy kapena polyurethane machitidwe opangira magwiridwe antchito apamwamba. Kusankhidwa kwa binder kumatsimikizira kulimba kwa utoto, kusinthasintha, komanso kukana kuvala.
Nkhumba zimapereka mtundu komanso mawonekedwe. Titanium dioxide imagwiritsidwa ntchito kwambiri popanga zoyera chifukwa chowala bwino komanso kuwunikira, pomwe zolembera zachikasu nthawi zambiri zimadalira mitundu yachikasu kapena organic. Kuti ziwonekere usiku, mikanda yagalasi imawonjezeredwa mkati mwa utoto kapena kuwaza pamwamba kuti apange retroreflectivity pamene nyali zowunikira zimawalira.
Zodzaza, monga calcium carbonate kapena silika, zimathandizira kuwongolera makulidwe, kapangidwe kake, ndi mtengo. Amathandizanso kuti skid resistance, yomwe ndi yofunikira pachitetezo chagalimoto ndi oyenda pansi, makamaka pamvula.
Zowonjezera - sinthani magwiridwe antchito. Izi zingaphatikizepo anti-settling agents, UV stabilizers, drying accelerators, ndi anti-skid materials. Mu utoto wokhala ndi madzi, zowonjezera zimathandizanso kuwongolera kuyenda komanso nthawi yowumitsa.
Kugwira ntchito kumadalira momwe zigawozi zimagwirira ntchito limodzi. Utoto wapamwamba kwambiri wapamsewu uyenera kuuma mwachangu, kukana ma abrasion ndi nyengo, kusunga mtundu pakapita nthawi, ndikukhalabe wowonekera usana ndi usiku. Mapangidwe amakono amayang'ana kwambiri machitidwe otsika a VOC ndi madzi kuti akwaniritse malamulo a chilengedwe pomwe akupereka ntchito zodalirika.
Mwachidule, penti yolembera mumsewu ndi chinthu chopangidwa mosamala kwambiri kuti misewu ikhale yotetezeka, yowoneka bwino, komanso yolimba chifukwa chazovuta zapamsewu.
