• I-Artificial Turf: Izinto ze-polyethylene zisetyenziswa ngokubanzi ekwenzeni i-turf eyenziweyo, ehlala ixesha elide kunye ne-aesthetics.

Amathuba ophuhliso lwezixhobo ze-polyethylene resin kwishishini lokwakha ziyathembisa, njengoko zinokuhlangabezana nemfuno eyandayo yokugcinwa kwamandla, ukukhuselwa kwendalo kunye nophuhliso oluzinzileyo. Ngokuphuculwa okuqhubekayo kobugcisa bokuvelisa kunye nokuphuhliswa kwezicelo ezintsha, izinto ze-polyethylene zilindeleke ukuba zidlale indima ebalulekileyo kwishishini lokwakha.

Ukusetyenziswa kwe-polyethylene resin kwi-powder coatings

I-polyethylene resin isetyenziswa ngokubanzi kwiingubo zomgubo. I-powder coating i-solvent-free, i-non-volatile organic coating kunye nokukhuselwa kwendalo, ukusebenza kakuhle, kunye nezibonelelo zokulondoloza amandla. I-polyethylene resin yimathiriyeli ekrwada ebalulekileyo yokwaleka komgubo, isetyenziswa ikakhulu kwezi ndawo zilandelayo:

• I-polyethylene resin ingasetyenziselwa njengeyona nto iphambili yokwenza ifilimu yokugqoka i-powder, kunye nokubambelela kakuhle, ukunyanzeliswa kokugqoka, kunye nokuchasana kwemozulu, enokukhusela ubuso bento edibeneyo kwi-corrosion kunye ne-oxidation.
• I-polyethylene resin ingasetyenziselwa i-plasticizer ye-powder coatings, enokuphucula ukuguquguquka kunye nokuchasana kwempembelelo yengubo, okwenza ukuba i-coating ihlale ixesha elide.
• I-polyethylene resin ingasetyenziswa njenge-agent yokulinganisa i-powder coatings, enokuthi iphucule i-gloss kunye nokugudiswa kwendawo yokugqoka, okwenza ukuba i-coating ibe ntle ngakumbi.
• I-polyethylene resin ingasetyenziselwa i-antioxidant ye-powder coatings, enokwandisa ubomi benkonzo yokugqoka kunye nokuphucula ukuqina kwayo.

Isishwankathelo, ukusetyenziswa kwe-polyethylene resin kwi-powder coatings kunokuphucula ukusebenza kunye nomgangatho wokugquma, ngelixa uhlangabezana neemfuno zokukhusela indalo kunye nethemba elibanzi lemarike.
