Masiku ano nthawi zambiri amagwiritsa ntchito zipangizo zamakono zomwe zimakulolani kupanga zinthu zochititsa chidwi pamakoma ndi padenga. Chimodzi mwa zipangizozi chinali mapepala apamwamba pazithunzi. Zimakhala zosavuta kumangiriza pamwamba, zotsika mtengo komanso zofunika kwambiri, zikhoza kujambulidwa mu mtundu uliwonse, zoyenera mkati mkati.
Mitundu yamtundu
Pogwiritsa ntchito mapepala, zipangizo zingapo zimagwiritsidwa ntchito:
- Duplex . Nsalu ziwiri zovekedwa pamapepala, zomwe zimabisa zobisala za makoma. Sagwirana pang'onopang'ono pamene amatha kupaka utoto. Chifukwa cha chiyanjano chawo cha 100% cha chilengedwe, nthawi zambiri amagwiritsidwa ntchito muzipinda za ana .
- Nsalu yopanda nsalu . Zida zofanana ndi mapepala, zomwe zimaphatikizapo zachirengedwe (cellulose ndi zina zotero) ndi mankhwala (polyester, vinyl). Mawotchi otere sakusowa kuti asungidwe ndi guluu ndipo amadikirira kuti alowe mu gawo lapansi - amagwiritsidwa mwachindunji ku khoma lopaka mafuta ndi glue. Pojambula pepala losasunthika padenga, ndibwino kugwiritsa ntchito pepala lofalitsa madzi pamtunda wa latex.
- Mapepala apanyumba . Chophimba chokongoletsera chomwe chili choyenera kwa zipinda zam'mwamba ndi msinkhu wa chinyezi (mwachitsanzo, bafa). Sakukopa fumbi, kulola mumlengalenga ndikukhala ndi zosangalatsa zosangalatsa. Kujambula ndi bwino kugwiritsa ntchito utoto wokhazikika pamadzi kapena ndi ma acrylic.
Kodi kujambula mapulaneti pa denga?
Kujambula, kupezeka kwa madzi (polyvinyl acetate), machulukidwe ndi machulukidwe a latex angagwiritsidwe ntchito. Mtengo wotsika mtengo ndi polyvinyl acetate pepala pa PVA-based. Ikhoza kugwiritsidwa ntchito muzipinda zouma popaka zojambula.
Penti yamafuta amatha kugwiritsidwa ntchito mu chipinda chilichonse chojambula. Phindu lake lalikulu ndi mndandanda wa mthunzi ndi kukana abrasion.
Maselo a latex amagwiritsidwa ntchito popanga wokongola silky pamwamba.
