Yintoni iPU?

I. Intshayelelo kwiPU

I-PU, okanye i-polyurethane, yimathiriyeli yokwenziwa equkethe ubukhulu becala i-polyurethane. Isikhumba sokwenziwa kwePU sisixhobo sesikhumba esinenyani esineempawu ezingcono zomzimba kunye nokuqina kunesikhumba sendalo.

Isikhumba sokwenziwa kwePU sinoluhlu olubanzi lwezicelo, kubandakanya ukuveliswa kwezihlalo zeemoto, iisofa, iibhegi, izihlangu, kunye nempahla, phakathi kwabanye. Iyathandeka ngobuhle, ikhululekile, kulula ukuyicoca kunye nokugcinwa kwayo, kwaye inciphisa imfuno yesikhumba sesilwanyana, ngaloo ndlela ihlangabezana neemfuno zokusingqongileyo ezithintela inkohlakalo yezilwanyana.

II. Uhlalutyo lwezinto ze-PU

1. Ukuqulunqwa

Inxalenye ephambili ye-PU yesikhumba sokwenziwa yi-polyurethane, eyenziwa ngokubambisana kwe-polyether okanye i-polyester ene-isocyanate. Ukongeza, isikhumba sokwenziwa kwePU sikwaqulethe izinto zokuzalisa, iiplasticizers, ii-pigments, kunye neearhente ezincedisayo.

2. Imbonakalo

Isikhumba sokwenziwa kwe-PU sityebile ngokuthungwa kunye nombala, kwaye sinokulinganisa iipateni ezahlukeneyo zesikhumba njengengwenya, inyoka, kunye nezikali zeentlanzi ukuhlangabezana neemfuno zeemveliso ezahlukeneyo.

3. IiPropati zoMzimba

Isikhumba sokwenziwa kwe-PU sineempawu ezibalaseleyo zomzimba ezinjengokuqina kokuqina, ukuxhathisa ukunxiba, ukumelana namanzi, kunye nokuguquguquka. Kwakhona kulula ukucoca nokugcina kunesikhumba sendalo, okwenza kube yinto ehlala ixesha elide.

4. Ixabiso lesicelo

Xa kuthelekiswa nofele lwendalo, iPU yesikhumba eyenziweyo ineengenelo ezithile ezifana neendleko eziphantsi, iindleko eziphantsi zemveliso, kwaye ayifuni ngesikhumba sesilwanyana, nto leyo eyenza ukuba ibe lukhetho olusebenzayo kubomi bale mihla esixekweni.

Ukuqukumbela, i-PU yesikhumba eyenziweyo yinto ekumgangatho ophezulu ebambela indawo eqhayisa ngobuhle, ukusebenza okukumgangatho ophezulu, kunye namaxabiso afanelekileyo, oko kuyenza ibe lukhetho oludumileyo kwintengiso. Njengoko ukuqhubela phambili kwetekhnoloji kunye neemfuno zentengiso zitshintsha, i-PU yesikhumba eyenziweyo inyanzelekile ukuba ibe nezicelo ezininzi kwixesha elizayo kumacandelo anje ngeemoto, ifenitshala, impahla, kunye neebhegi, ukukhankanya ezimbalwa.
