Yini lesikhumba se-solvent-free pu?

Isikhumba se-solvent-free pu yisikhumba sokufakelwa esivumelekile semvelo esinciphisa noma sikuvikele ngokuphelele ukusetshenziswa kwezinto eziphilayo ze-organic kwinqubo yaso yokukhiqiza. Izinqubo zokukhiqiza zesikhumba zendabuko ze-PU (Polyurethane) zivame ukusebenzisa izixazululo ze-organic njengezidili noma izengezo, ezingaba nemiphumela emibi yemvelo nezempilo. Ukunciphisa lo mphumela, i-solvent-free pu lesikhumba isebenzisa amasu ahlukene wokukhiqiza, njengobuchwepheshe obususelwa emanzini noma obunye ubuchwepheshe bendalo enobuhlakani, ukufaka esikhundleni sendabuko yendabuko yendalo.

Ngakho-ke kukhiqizwe kanjani i-solvent-free pu lesikhumba?
Ake siqale ngokubheka ukuthi i-solvent-free pu lesikhumba ikhiqizwa ngayo:
1. Ukulungiswa kwendwangu eyisisekelo: Okokuqala, udinga ukulungiselela indwangu eyisisekelo, engaba yikotini noma ezinye izinto zokwenziwa. Le nto engaphansi izoba yisisekelo sesikhumba se-pu,
2. I-Primer yokuhlanganisa: Faka ungqimba we-primer endwangu eyisisekelo. Lesi sigaba se-substrate sivame ukuba yi-polyurethane (pu), enezakhiwo ezinhle zokunamathela futhi zigqoke ukumelana.
3. Ukuhlanganisa ungqimba oluphezulu: Ngemuva kokuthi i-Primer eyomile, faka ungqimba lothando. Le nhlangano nayo yenziwa nge-polyurethane, enquma ukubukeka nokuzizwa ngesikhumba se-pu. Ezinye izingxenye zobuso zingadinga ukwelashwa okukhethekile, njengokuphamba, ukuphrinta noma ukucwaswa kwesikhumba kwesikhumba, ukwandisa ukuthungwa nobuhle besikhumba.

5 Lezi zimbozo azikhiphi izixazululo ze-organic noma zikhulule amanani amancane kakhulu we-solvents ngesikhathi senqubo yokuhlanganisa, ngaleyo ndlela anciphise ukungcoliswa kwemvelo kanye nomthelela empilweni yabasebenzi.

Kungani isikhumba se-solvent-free pu sithandwa manje?
Ngabe sonke sinenkinga, lapho siya ezitolo ukuzothenga i-sofa noma ifenisha, sibone ukuthi u-sofa wesikhumba omhlophe noma ongenakukwazi ukukhathazeka, kodwa futhi ungazikhiphi, kepha asinakuthi cha, kepha asize sikhathazeke, singakusiza, singakusiza ngale nkinga. Isikhumba se-solvo-free pu nokuvikelwa kwayo kwezemvelo, ukusebenza okuphezulu nezimpawu ezisebenzayo, kepha futhi kunezimpawu zokuphikiswa okungcolile, ukumelana nokuhlanzeka okulula, ngakho-ke singakwazi ukukhathazeka ngezingane ezimhlophe ezingcolile, azisakhathazeki ngezingane ezinamahloni ezidonsa kusofa.
Isikhumba se-solvent-free pu sihlangabezana nezidingo ezimbili zabathengi banamuhla kanye nabakhiqizi bekhwalithi yomkhiqizo kanye nomsebenzi wezemvelo, okwenza kube inketho enobungani bezemvelo futhi esimeme futhi ngenxa yalokho iyathandeka emakethe.
