Tiyeni tione chimene chikuphimba padenga. Mfundo yakuti ziwalo zomangidwa ndi makoma ndi denga, makamaka ngati denga likudalira pamafunika zokongoletsera, popeza kuti silingathe kukonzanso denga. Nthawi zina zimakhala zofunikira kubisala zolakwika zina. Kamodzi kamagwiritsidwanso ntchito yokongoletsera yowonjezera, kanyumba, koma izi sizikhala zabwino nthawi zonse. Chifukwa cha kupita patsogolo kwa zamakono mpaka lero, timatha kupanga denga pogwiritsira ntchito mapuloteni otchingidwa ndi polyurethane

Zinthu zomwe zimapangidwira zimakhala ndi kukwera kwakukulu kosalamba komanso kukana zowawa zamalonda. Chokongoletsera choterechi chimamaliza chithunzi chonse cha mkati. Izi ndizowona makamaka pazithunzi za zomangamanga (kupezeka kwa zipilala ndi ziwonetsero). Komanso kuti muzindikire kuti, muli ndi bolodi lopangidwa ndi polyurethane, mungagwiritse ntchito masewerawa, izi zikhoza kuwonjezera gawo la mkondano mwa kukonza chipinda .

Kuyika zowonongeka kuchokera pansi pa polyurethane
Musanayambe kukonza siling'i - kuumba kwa polyurethane, muyenera kudziwa malamulo angapo osavuta, omwe ndi awa:
- Denga losasunthika lomwe limachokera ku polyurethane liyenera kukonzedwa pamakoma oponyedwa. Kuwongolera koteroko kumakhala kodalirika kwambiri kuposa kudula pazithunzi za pepala kapena penti;
- Ndikofunika kukonzekera pamwamba poyamba kuchiyeretsa ndikuyipitsa. Zomalizazi zikhoza kuchitidwa ndi yankho la alkali, mwachitsanzo, gwiritsani ntchito mzunguli wamba;
- ndi kofunika kuti muzitha kumanga makomawo ndi wothandizira ndi malo oyambira.
Mapuloteni osungunuka a polyurethane pamakona angapangidwe mapeto, omwe sayenera kuyambitsa mavuto. Pothandizidwa ndi chida chopentala chophweka, monga mpando, ndipo chifukwa cha kusowa kwake mothandizidwa ndi mpeni wamba wodula, zidutswa zimapangidwa. Chofunika kwambiri ndi chakuti ziwalo pakati pawo ziyenera kutetezedwa ndi guluu. Ndi chiyani chomwe chingamangirire chophimba padenga kuchokera ku polyurethane? Kuyika pulasitiki yotere kumagwiritsa ntchito zomatira kapena glue, zomwe zimagwiritsa ntchito plinth.
