Umbhobho wentsimbi enemigca yepolyurethane
Umbhobho wentsimbi ofakwe ngepolyurethane yimveliso yombhobho ekwaziyo ukumelana nokuguguleka kakhulu, esetyenziswa kakhulu kwimibhobho yokucubungula izimbiwa kunye nemibhobho yokuhambisa umsila. Isikhululo samandla sefosili-fuel sisebenzisa lombhobho kwiinkqubo zokususa amalahle nothuthu, kunye nakwimizi-mveliso yeoyile, iikhemikhali, isamente kunye neenkozo.
Iimbonakalo
1. Ayigugi
2. Thintela Ukwandisa Ubungakanani
3. Ukumelana nokugqwala
4. Ukuxhathisa ukwaluphala kwe-hydrolysis
5. Ukuqina okuphezulu
6. Ukumelana noMothuko woMatshini
7. Ukuzithambisa ngokwakho
I-Arex ikhetha i-master batch ye-premium enendlela ehlengahlengisiweyo ye-nano ukuqinisa umsebenzi wezinto ze-polyurethane. Yenza iimveliso ezifakwe kwi-polyurethane zibe nesakhiwo seekhemikhali esizinzileyo kwaye ibonise ukuguquguquka kwayo kwimeko yokusebenza.
Umbhobho wentsimbi ogqunywe nge-polyurethane, njengenye yelungelo elilodwa lomenzi wemveliso yemigodi yasekhaya eArex, uthandwa kwaye usetyenziswa ngabathengi bethu bemigodi.
