Kuyini isikhumba se-pu esingenazo izinyibilikisi?

Isikhumba se-PU esingenazo izinyibilikisi siyisikhumba sokwenziwa esinobungani nemvelo esinciphisa noma sigwema ngokuphelele ukusetshenziswa kwezinyibilikisi eziphilayo enkambisweni yaso yokukhiqiza. Izinqubo zokukhiqiza isikhumba se-PU (polyurethane) sendabuko zivame ukusebenzisa izinyibilikisi eziphilayo njengezinyibilikisi noma izithasiselo, ezingaba nemiphumela emibi kwezemvelo nasempilweni. Ukuze kuncishiswe lo mthelela, isikhumba se-PU esingenazo izinyibilikisi sisebenzisa amasu ahlukene okukhiqiza, njengobuchwepheshe obusekelwe emanzini noma obunye ubuchwepheshe obunobungani nemvelo, ukuze kuthathelwe indawo izinyibilikisi zendabuko eziphilayo.

Ngakho-ke isikhumba se-PU esingenazo izinyibilikisi sikhiqizwa kanjani?
Ake siqale sibheke ukuthi isikhumba se-PU esingenazo izinyibilikisi sikhiqizwa kanjani:
1. Ukulungiswa kwendwangu eyisisekelo: Okokuqala, udinga ukulungisa indwangu eyisisekelo, engaba ukotini noma ezinye izinto zokwenziwa. Le substrate izoba yisisekelo sesikhumba se-PU,
2. I-primer yokumboza: Faka ungqimba lwe-primer endwangwini eyisisekelo. Le substrate ngokuvamile iyi-polyurethane (PU), enezakhiwo ezinhle zokunamathela kanye nokumelana nokuguguleka.
3. Ukumboza ungqimba oluphezulu: Ngemva kokuba i-primer yomile, faka ungqimba lothando. Lolu ngqimba lwenziwe nge-polyurethane, enquma ukubukeka nomuzwa wesikhumba se-PU. Ezinye izingxenye zobuso zingadinga ukwelashwa okukhethekile, njengokumboza, ukuphrinta noma ukuthungwa kwesikhumba okuzenzisa, ukuze kwandiswe ukuthungwa nobuhle besikhumba.
4. Ukomisa nokulungisa: Ngemva kokuqeda ukugqoka kwasehlobo, isikhumba se-PU sithunyelwa ekamelweni lokomisa noma ngezinye izindlela zokulungisa, ukuze i-primer kanye nongqimba olungaphezulu kuphole ngokuphelele futhi kuhlanganiswe.
5. Ukuqeda nokusika: Ngemva kokuba isikhumba se-PU sesicutshunguliwe, inqubo yokuqeda idinga ukwenziwa, okuhlanganisa nokusika kube ngesimo nosayizi owufunayo ukuze kwenziwe imikhiqizo yesikhumba yokugcina, njengezikhwama, izicathulo, njll. Iphuzu elibalulekile kuyo yonke inqubo ukusetshenziswa kopende we-polyurethane (PU) ongenaso isinyibilikisi. Lezi zimbozo azikhiphi izinyibilikisi eziphilayo noma zikhiphe inani elincane kakhulu lezinyibilikisi ngesikhathi senqubo yokugqoka, ngaleyo ndlela kunciphisa ukungcola kwemvelo kanye nomthelela empilweni yabasebenzi.

Kungani isikhumba se-pu esingenazo izinyibilikisi sithandwa kakhulu manje?
Ingabe sonke sinenkinga, uma siya esitolo esikhulu ukuyothenga isofa noma ifenisha, sibona isofa lesikhumba elimhlophe elihle nelinemfashini noma ifenisha lesikhumba, sifuna ukuyithenga, kodwa futhi sikhathazeke ngokuthi isofa lesikhumba elimhlophe alimelani nokungcola, alimelani nokuklwebheka, alilula ukulihlanza, ngakho-ke sizoyeka kaningi ngenxa yalesi sizathu, manje ungakhathazeki, asinaso isikhumba se-PU esinyibilikayo, singakusiza ngale nkinga. Isikhumba se-PU esingenaso i-Solvo esinokuvikelwa kwemvelo, ukusebenza okuphezulu kanye nezici eziningi ezisebenzayo, kodwa futhi sinezici zokumelana nokungcola, ukumelana nokuklwebheka kanye nokuhlanza okulula, ukuze sikhethe isikhumba se-PU esingenaso i-solvo esenziwe ngesofa elimhlophe, asisadingeki sikhathazeke ngokuthi isofa elimhlophe alingcolile, asisakhathazeki ngezingane ezigangile ezidweba kusofa ngepeni.
Isikhumba se-PU esingenaso isinyibilikisi sihlangabezana nezidingo ezimbili zabathengi nabakhiqizi besimanje ngekhwalithi yomkhiqizo kanye nomthwalo wemfanelo wezemvelo, okwenza kube inketho enobungani nemvelo futhi esimeme futhi ngenxa yalokho ithandwa kakhulu emakethe.
