Yintoni i-PU?

I. Intshayelelo kwi-PU

I-PU, okanye i-polyurethane, yinto eyenziwe ngokwenziwa equlathe ikakhulu i-polyurethane. Isikhumba esenziwe ngokwenziwa se-PU sisixhobo sesikhumba esibonakalayo esinezinto ezibonakalayo ezingcono kwaye sihlala ixesha elide kunesikhumba sendalo.

Isikhumba esenziwe nge-PU sinoluhlu olubanzi lwezicelo, kubandakanya ukuveliswa kwezihlalo zeemoto, iisofa, iibhegi zesandla, izihlangu, kunye neempahla, phakathi kwezinye. Simnandi ngobuhle, sikhululekile, kulula ukusicoca nokusigcina sicocekile, kwaye sinciphisa imfuno yesikhumba sezilwanyana, ngaloo ndlela sihlangabezana neemfuno zokusingqongileyo ezithintela ukuxhatshazwa kwezilwanyana.

II. Uhlalutyo lwezixhobo zePU

1. Ukwakhiwa

Eyona nto iphambili kwisikhumba esenziwe nge-PU yi-polyurethane, eyenziwa kukudibana kwe-polyether okanye i-polyester ne-isocyanate. Ukongeza, isikhumba esenziwe nge-PU sikwanazo nezinto zokuzalisa, iiplastiki, ii-pigment, kunye nee-arhente ezincedisayo.

2. Inkangeleko

Isikhumba esenziwe nge-PU sityebile ngombala, kwaye sinokulinganisa iipateni ezahlukeneyo zesikhumba ezifana neengwenya, iinyoka kunye namaxolo eentlanzi ukuze kuhlangatyezwane neemfuno zeemveliso ezahlukeneyo.

3. Iimpawu ezibonakalayo

Isikhumba esenziwe nge-PU sineempawu ezintle kakhulu zomzimba ezifana nokuqina kokutsalwa, ukumelana nokuguguleka, ukumelana namanzi, kunye nokuguquguquka. Kulula kakhulu ukusicoca nokuyilungisa kunesikhumba sendalo, nto leyo eyenza sihlale ixesha elide.

4. Ixabiso lesicelo

Xa kuthelekiswa nesikhumba sendalo, isikhumba esenziwe nge-PU sineengenelo ezithile ezifana nexabiso eliphantsi, iindleko zokuvelisa eziphantsi, kunye nokungadingi isikhumba sezilwanyana, nto leyo eyenza ukuba sibe lukhetho olufanelekileyo kubomi besixeko sanamhlanje.

Ukuqukumbela, isikhumba esenziwe nge-PU sisixhobo esikumgangatho ophezulu esinobuhle obuhle, ukusebenza kakuhle, kunye namaxabiso afanelekileyo, nto leyo eyenza ukuba sibe lukhetho oludumileyo kwimarike. Njengoko ubuchwepheshe buqhubeka kwaye iimfuno zemarike zitshintsha, isikhumba esenziwe nge-PU siya kuba nezicelo ezininzi kwixesha elizayo kumacandelo afana neemoto, ifenitshala, impahla, kunye neebhegi, ukubala ezimbalwa.
