I-Pu Safety Shoe Sole System
I-Pu Safety Shoe Sole System
IINTSHAYELELO
Inkqubo ye-PU Safety shoe-sole isetyenziselwa ukwenza izihlangu ezikhuselekileyo kunye neentsimbi zangaphakathi. Yinkqubo ye-PU esekelwe kwi-polyester, iqulethe izinto ezine, i-polyol, i-ISO, i-hardner kunye ne-catalyst. Ukuqhubekekiswa kwenkqubo ngamacandelwana amabini. I-catalyst, i-agent enzima, i-ejenti yokuvuthela kunye ne-pigment kufuneka ixutywe ngokucokisekileyo kunye ne-polyol component EXD-3270A, uze udibanise ne-ISO component EXD-3119B yokwenza iimpahla zokugqibela.
IIPROPATI ZOMZIMBA
A, Iipali zangaphakathi zesihlangu sokhuseleko indlela yokulungisa:
