Chitoliro chachitsulo chopangidwa ndi polyurethane
Polyurethane alimbane zitsulo chitoliro ndi mkulu kuvala kugonjetsedwa payipi mankhwala, amene chimagwiritsidwa ntchito mu mipope processing mchere ndi michira kufala mapaipi.Malo opangira magetsi opangidwa ndi mafuta oyambira pansi amagwiritsa ntchito mapaipiwa pochotsa malasha ndi phulusa, komanso m'mafakitale amafuta, mankhwala, simenti ndi mbewu.
Mawonekedwe
1. Zosavala
2.Prevent Makulitsidwe
3.Kukaniza Corrosion
4. Kukana kukalamba kwa hydrolysis
5. Kuthamanga Kwambiri
6. Kukaniza Kugwedezeka Kwamakina
7. Kudzipaka mafuta
Arex amasankha premium master batch yokhala ndi nano-modified njira kuti alimbikitse ntchito ya polyurethane.Zimapangitsa zinthu zopangidwa ndi polyurethane kukhala ndi mawonekedwe okhazikika amankhwala ndikuwonetsa kusinthika kwake pakagwiritsidwe ntchito.
The polyurethane alimbane zitsulo chitoliro, monga mmodzi wa patent zoweta za mankhwala migodi Arex, ndi wotchuka ndi ntchito ndi makasitomala athu migodi.
Kuyerekeza katundu pakati wamba polyurethane ndi nano-modified polyurethane
