Yintoni ufele lwepu olunganyibilikiyo?

Isikhumba se-PU esinganyibilikiyo sisixhobo sesikhumba sokwenziwa esisingqongileyo esinciphisa okanye sithintele ngokupheleleyo ukusetyenziswa kwezinyibilikisi zendalo kwinkqubo yokwenziwa kwayo. I-PU yemveli (i-polyurethane) iinkqubo zokwenziwa kwesikhumba zihlala zisebenzisa i-solvents eziphilayo njenge-diluents okanye izongezo, ezinokuthi zibe nemiphumo emibi yendalo kunye nempilo. Ukunciphisa le mpembelelo, i-PU yesikhumba engena-solvent isebenzisa iindlela ezahlukeneyo zokuvelisa, ezifana nobuchwepheshe obusekelwe emanzini okanye obunye ubugcisa obunobuhlobo bendalo, ukubuyisela izinyibilikisi zendalo zendalo.

Ke iveliswa njani ngesikhumba se-PU enganyibilikiyo?
Makhe siqale sijonge indlela eveliswa ngayo ulusu lwePU olunganyibilikiyo:
1. Ukulungiswa kwendwangu yesiseko: Okokuqala, kufuneka ulungiselele ingubo yesiseko, enokuthi ibe yikotoni okanye ezinye izinto zokwenziwa. Le substrate iya kuba sisiseko sesikhumba sePU,
2. I-Coating primer: Faka i-layer ye-primer kwi-cloth yesiseko. Le substrate idla ngokuba yi-polyurethane (PU), eneempawu ezintle zokubambelela kunye nokumelana nokugqoka.
3. Ukugquma umaleko ophezulu: Emva kokuba i-primer yomile, sebenzisa uluhlu lothando. Olu luhlu lwenziwe nge-polyurethane, olumisela imbonakalo kunye nokuziva kwesikhumba sePU. Ezinye iindawo zomphezulu zingafuna unyango olukhethekileyo, olufana ne-embossing, ukuprinta okanye ukuxelisa ukuthungwa kwesikhumba, ukwandisa ukuthungwa kunye nobuhle besikhumba.
4. Ukomisa kunye nokunyanga: Emva kokugqiba iingubo zasehlotyeni, i-PU yesikhumba ithunyelwa kwigumbi lokumisa okanye ngezinye iindlela zokunyanga, ukwenzela ukuba i-primer kunye nomgangatho ophezulu uphiliswe ngokupheleleyo kwaye udibene.
5. Ukugqiba kunye nokusika: Emva kokuba i-PU yesikhumba icutshungulwe, inkqubo yokugqiba kufuneka iqhutywe, kubandakanywa ukusika kwisimo esifunwayo kunye nobukhulu ukuze wenze iimveliso zesikhumba zokugqibela, ezifana neengxowa, izicathulo, njl. Ezi zogquma azikhuphi izinyibilikisi eziphilayo okanye zikhuphe izinyibilikisi ezincinci kakhulu ngexesha lenkqubo yokugquma, ngaloo ndlela zinciphisa ukungcoliseka kwendalo kunye nefuthe kwimpilo yabasebenzi.

Kutheni le nto ulusu lwe-pu olunganyibilikiyo luthandwa kakhulu ngoku?
Ngaba sonke sinengxaki, xa sisiya kwivenkile yokuthenga i-sofa okanye ifenitshala, sibone i-sofa yesikhumba emhlophe kunye nefashoni emhlophe okanye ifenitshala yesikhumba, sifuna ukuthenga, kodwa ixhala malunga ne-sofa yesikhumba emhlophe ayinakumelana nokungcola, ayinqandeki, ayikho lula ukuyicoca, amaxesha amaninzi aya kunikezela ngenxa yesi sizathu, ngoku ungakhathazeki, awunayo ingxaki, awunayo le ngxaki. Isikhumba se-SO-free PU kunye nokukhuselwa kwayo kokusingqongileyo, ukusebenza okuphezulu kunye neempawu zemisebenzi emininzi, kodwa ineempawu zokumelana nokungcola, ukuxhathisa ukukhuhla kunye nokucoca lula, ngoko ke sinokukhetha i-PU yesikhumba se-solvo-free eyenziwe ngesofa emhlophe, akusekho kukhathazeka malunga nesofa emhlophe ayimdaka, ayisenaxhala labantwana abakhohlakeleyo abazoba kwisofa ngepeni.
Isikhumba se-PU esinganyibilikiyo sihlangabezana neemfuno ezimbini zabathengi banamhlanje kunye nabavelisi bomgangatho wemveliso kunye noxanduva lokusingqongileyo, nto leyo eyenza ukuba ibe lukhetho olulungele ukusingqongileyo noluzinzileyo kwaye ke ngoko ithandwa kakhulu kwintengiso.
