Putty poda imhando yezvivakwa zvekushongedza zvinhu, izvo zvikuru zvinoumba talcum poda uye glue. Muchena mutsvuku pamusoro peimba isina chinhu yakangotengwa ndeye putty. Kazhinji kuchena kweputty kuri pamusoro pe90 ° uye kunaka kuri pamusoro pe330 °.
Putty rudzi rwechigadziko chinoshandiswa kugadzirisa madziro, chinoisa hwaro hwakanaka hwenhanho inotevera yekushongedza (kupenda uye Wallpaper). Putty yakakamurwa kuita marudzi maviri: putty mukati memadziro uye putty pamadziro ekunze. External wall putty inogona kuramba mhepo nezuva, saka ine yakanaka gelation, yakakwirira simba uye yakaderera nharaunda index. Iyo yakazara index ye putty mumadziro emukati yakanaka, uye ine hutsanana uye ine hushamwari. Nokudaro, rusvingo rwemukati harisi rekushandisa kunze uye rusvingo rwekunze harisi rekushandisa mukati. Maputty anowanzo akavakirwa pagypsum kana simende, saka nzvimbo dzakakasharara dziri nyore kusunga zvakasimba. Nekudaro, panguva yekuvaka, zvichiri kudikanwa kukwesha dhizaini yeanoshanda mumiriri pachigadziko kuti usimbise hwaro uye uvandudze kunamatira kwemadziro, kuitira kuti putty igone kusungirirwa zviri nani kune hwaro.
Vazhinji vashandisi veputty poda vanofanirwa kubvuma kuti kupera kweputty idambudziko rakakura. Ichaita kuti pende ye latex iwire pasi, pamwe nekuputira uye kuputika kweputty layer, izvo zvinozokonzera kuputika kwependi ye latex.
De-upfu uye kuchena kweputty pari zvino ndiwo matambudziko akajairika mushure mekuvaka putty. Kuti tinzwisise zvikonzero zveputty poda de-powdering, isu tinofanira kutanga tanzwisisa izvo zvakakosha zvinhu zvakasvibirira uye misimboti yekurapa yeputty poda, uye tozobatanidza madziro emadziro panguva yekuvaka putty Kuoma, kunyura kwemvura, tembiricha, kuoma kwemamiriro ekunze, nezvimwe.
