Yintoni isikhumba se-pu esingenazinyibilikisi?

Isikhumba se-PU esingenazo izinyibilikisi sisikhumba esenziweyo esinobuhlobo nokusingqongileyo esinciphisa okanye siphephe ngokupheleleyo ukusetyenziswa kwezinyibilikisi zendalo kwinkqubo yaso yokwenziwa. Iinkqubo zokwenza izikhumba ze-PU (polyurethane) zemveli zihlala zisebenzisa izinyibilikisi zendalo njengezinto zokudibanisa okanye izongezo, ezinokuba nemiphumo emibi kwindalo nakwimpilo. Ukunciphisa le mpembelelo, isikhumba se-PU esingenazo izinyibilikisi sisebenzisa iindlela ezahlukeneyo zokwenza, ezifana netekhnoloji esekwe emanzini okanye ezinye iiteknoloji ezinobuhlobo nokusingqongileyo, ukuze zithathe indawo yezinyibilikisi zendalo zemveli.

Ngoko ke, ulusu lwe-PU olungenazinyibilikisi lwenziwa njani?
Masiqale sijonge indlela eveliswa ngayo ulusu lwe-PU olungenazinyibilikisi:
1. Ukulungiswa kwelaphu elisisiseko: Okokuqala, kufuneka ulungiselele ilaphu elisisiseko, elinokuba yikotoni okanye ezinye izinto ezenziwe ngokwenziwa. Le substrate iya kuba sisiseko sesikhumba se-PU,
2. I-primer yokugquma: Faka umaleko we-primer kwilaphu elisisiseko. Le substrate idla ngokuba yi-polyurethane (PU), eneempawu zokunamathela ezilungileyo kunye nokumelana nokuguguleka.
3. Ukugquma umaleko ongaphezulu: Emva kokuba iprimer yomile, faka umaleko wothando. Olu maleko lwenziwe nge-polyurethane, emisela inkangeleko kunye nokuvakala kwesikhumba se-PU. Ezinye iindawo zomphezulu zinokufuna unyango olukhethekileyo, olufana nokugquma, ukuprinta okanye ukugquma kwesikhumba okufana nomfanekiso, ukuze kwandiswe ukugquma kunye nobuhle besikhumba.
4. Ukomisa nokulungisa: Emva kokugqiba ukugcoba ehlotyeni, ulusu lwe-PU luthunyelwa kwigumbi lokomisa okanye ngezinye iindlela zokuthambisa, ukuze i-primer kunye nomaleko womphezulu zinyangeke ngokupheleleyo kwaye zidityaniswe.
5. Ukugqiba nokusika: Emva kokuba ulusu lwe-PU lusetyenzisiwe, inkqubo yokugqiba kufuneka yenziwe, kuquka nokusika imo nobukhulu obufunekayo ukuze kwenziwe iimveliso zokugqibela zesikhumba, ezifana neengxowa, izihlangu, njl. Ingongoma ephambili kuyo yonke le nkqubo kukusetyenziswa kwepeyinti ye-polyurethane engenasombululo (PU). Ezi ngubo azikhuphi izinyibilikisi zendalo okanye zikhuphe izinyibilikisi ezincinci ngexesha lenkqubo yokugcoba, ngaloo ndlela kunciphisa ungcoliseko lokusingqongileyo kunye nempembelelo kwimpilo yabasebenzi.

Kutheni le nto isikhumba se-pu esingenazinyibilikisi sithandwa ngakumbi ngoku?
Ngaba sonke sinengxaki, xa sisiya kwivenkile enkulu siyokuthenga isofa okanye ifenitshala, sibona isofa emhlophe yesikhumba entle nenemfashini okanye ifenitshala yesikhumba, sifuna ukuyithenga, kodwa sixhalabele nokuba isofa emhlophe yesikhumba ayimelani nokungcola, ayimelani nokukrwela, ayilula ukuyicoca, amaxesha amaninzi siya kuyiyeka ngenxa yesi sizathu, ngoku ungakhathazeki, asinaso isinyibilikisi sesikhumba se-PU, sinokukunceda ngale ngxaki. Isikhumba se-PU esingenaSolvo sinokhuseleko lokusingqongileyo, ukusebenza okuphezulu kunye neempawu ezininzi ezisebenzayo, kodwa sikwanazo neempawu zokuxhathisa ukungcola, ukumelana nokukrwela kunye nokucoca okulula, ukuze sikwazi ukukhetha isikhumba se-PU esingenaso isolvo esenziwe ngesofa emhlophe, asisaxhalabi ngokuba isofa emhlophe ayingcolanga, asisaxhalabi ngabantwana abangcolileyo abazoba kwisofa ngepeni.
Isikhumba se-PU esingenasinyibilikisi sihlangabezana neemfuno ezimbini zabathengi banamhlanje kunye nabavelisi bomgangatho wemveliso kunye noxanduva lokusingqongileyo, nto leyo eyenza ukuba ibe lukhetho olunobuhlobo nokusingqongileyo noluzinzileyo kwaye ngenxa yoko luthandwa kakhulu kwimarike.
