Dulani pazitsulo

Masiku ano, pali mitundu yambiri yophimba pansi pa malo okhala komanso osakhala. Pa nthawi imodzimodziyo, mtengo wapatali wa matabwa unali ndipo umakhalabe ndi akale okalamba . Malo apansi apangidwa ndi matabwa achilengedwe ali ndi mawonekedwe abwino, ndi ophweka kugwiritsa ntchito ndi okhazikika mokwanira. Komabe, kwa utumiki wautali komanso wamtengo wapatali, iwo ayenera kukonzedwa. Mitundu yayikulu ya zokutira pansi pa matabwa ndi monga varnishes, zojambula, zoyamba ndi zoperekera. Tiyeni tiwone kuti ndi chithunzi chotani chomwe chiri bwino kupenta nkhuni.

Penti yabwino kwambiri pamatabwa

Posankha utoto uwu, choyamba, muyenera kuganizira mtundu wa nkhuni, zomwe zimagwira ntchito mu chipinda chino (chinyezi, msinkhu wotayirira), zogwirizana ndi zipangizo zomwe zilipo kale komanso zowonjezeredwa. Pali mitundu yambiri ya utoto wa nkhuni , koma zonsezi zingagawidwe m'magulu akulu atatu.

1. Zosasintha (izi, makamaka, lacquers, impregnations ndi glazes) - amateteza mtengo ku makina opanikizika ndi ultraviolet miyezi, komanso kutsimikizira masoka a mtengo. Pansi, opangidwa ndi chovala choyera, amapeza zokongola.
2. Opaque (enamel). Kuphimba uku kwagwiritsidwa ntchito kwa nthawi yaitali ndipo kumasiyana ndi mtengo wake wotsika. Mapuloteni ndi ophweka komanso oyenera kugwiritsa ntchito: pamene kujambula pamwamba pa filimu kumapangidwira. Kujambula uku ndikutentha kwa onse. Sichilowa mkati mwa mtengo monga momwe zimakhalira ndi varnish, choncho sichikhazikika kwambiri. Kwa mitundu yochepetsetsa ya pepala lopangidwa ndi alkyd ndi vinyl chloride, ndi miyala ya polyurethane ndi ya acrylic ndi yamakono komanso yosagonjetsedwa. Nthawi zambiri ma seamel amagwiritsidwa ntchito ku zipinda zotere zomwe zimakhala chinyezi.
3. Pulogalamu yowonjezereka yopangidwa ndi matabwa - mitengo yamakono, yapamwamba komanso yosagwira ntchito. Mitengo yomwe imakhala ndi penti yogawidwa, imakhala yodabwitsa kwambiri - mphamvu ya kuteteza, kutentha kwa mpweya (mosiyana ndi mitundu yonse ya mapulogalamu omwe amapuma) ndi chisanu chakumana.

Kuchotsa pepala kuchokera pamatabwa kumaperekedwa mothandizidwa ndi zisoti zapadera, zofanana ndi mtundu wa utoto, kapena njira zamakina komanso zamatentho.
