Iyini isikhumba se-pu esingancibiliki?

Isikhumba se-PU esingancibilikisiwe siyisikhumba sokwenziwa esivumelana nemvelo esinciphisa noma esigwema ngokuphelele ukusetshenziswa kwezinyibilikisi zemvelo ohlelweni lwaso lokukhiqiza. Izinqubo zokukhiqiza isikhumba ze-PU (i-polyurethane) yendabuko ngokuvamile zisebenzisa izincibilikisi zemvelo njengezixuku noma izithasiselo, ezingaba nemiphumela engemihle kwezemvelo nempilo. Ukuze kuncishiswe lo mthelela, isikhumba se-PU esingancibilikisiwe sisebenzisa amasu okukhiqiza ahlukene, njengobuchwepheshe obusekelwe emanzini noma obunye ubuchwepheshe obunobungani bemvelo, ukuze kuthathelwe indawo izincibilikisi zemvelo zendabuko.

Ngakho-ke isikhumba se-PU esingancibiliki sikhiqizwa kanjani?
Ake siqale sibheke ukuthi isikhumba se-PU esingancibiliki sikhiqizwa kanjani:
1. Ukulungiswa kwendwangu yesisekelo: Okokuqala, udinga ukulungisa indwangu yesisekelo, okungaba ukotini noma ezinye izinto zokwenziwa. Le substrate izoba yisisekelo se-PU lesikhumba,
2. I-Coating primer: Faka ungqimba lwe-primer phezu kwendwangu yesisekelo. Le substrate ngokuvamile i-polyurethane (PU), enezindawo ezinhle zokunamathela kanye nokumelana nokugqoka.
3. Ukumboza ungqimba olungaphezulu: Ngemva kokuba i-primer isomile, sebenzisa ungqimba lothando. Lolu ngqimba luphinde lwenziwe nge-polyurethane, enquma ukubukeka nokuzwakala kwesikhumba se-PU. Ezinye izingxenye zobuso zingadinga ukwelashwa okukhethekile, njengokugqamisa, ukuphrinta noma ukulingisa ukuthungwa kwesikhumba, ukwandisa ukuthungwa nobuhle besikhumba.
4. Ukomisa nokuphulukisa: Ngemva kokuqeda ukugqoka kwehlobo, isikhumba se-PU sithunyelwa ekamelweni lokumisa noma ngezinye izindlela zokuphulukisa, ukuze i-primer kanye nongqimba olungaphezulu lwelashwe ngokugcwele futhi luhlanganiswe.
5. Ukuqeda nokusika: Ngemva kokuba isikhumba se-PU sicutshungulwe, inqubo yokuqeda idinga ukwenziwa, kuhlanganise nokusika ekubunjweni okufunayo nosayizi ukuze kwenziwe imikhiqizo yokugcina yesikhumba, njengezikhwama, izicathulo, njll. Lezi zingubo zokumboza azikhiphi izincibilikisi eziphilayo noma zikhiphe amanani amancane kakhulu ezincibilikisi phakathi nenqubo yokumboza, ngaleyo ndlela zehlise ukungcoliswa kwemvelo kanye nomthelela empilweni yabasebenzi.

Kungani isikhumba se-pu esingancibiliki sithandwa kakhulu manje?
Ingabe sonke sinenkinga, lapho siya enxanxatheleni yezitolo siyothenga usofa noma ifenisha, bheka usofa wesikhumba omhlophe omuhle nemfashini noma ifenisha yesikhumba, sifuna ukuthenga, kodwa futhi sikhathazeke ngokuthi usofa wesikhumba omhlophe awumelani nokungcola, awumelani nokuklwebheka, akulula ukuwuhlanza, izikhathi eziningi uzoyeka ngenxa yalesi sizathu, manje ungakhathazeki, asinaso lesi sixazululo se-PU. Isikhumba se-PU esingenasolvo esinokuvikelwa kwemvelo, ukusebenza okuphezulu kanye nezici eziningi ezisebenzayo, kodwa futhi sinezici zokumelana nokungcola, ukumelana nokuklwebheka nokuhlanza kalula, ukuze sikwazi ukukhetha isikhumba se-PU esingenasosolvo esenziwe ngosofa omhlophe, akusadingeki sikhathazeke ngokuthi usofa omhlophe awungcolile, asisakhathazeki ngezingane ezigangile ezidweba kusofa ngepeni.
Isikhumba se-PU esingancibilikisiwe sihlangabezana nezidingo ezimbili zabathengi nabakhiqizi besimanje ngekhwalithi yomkhiqizo kanye nesibopho semvelo, okuyenza ibe inketho evumelana nemvelo futhi esimeme futhi ngenxa yalokho iya ngokuya ithandwa emakethe.
