• Ifilimu yaphansi: Ifilimu ye-Polyethylene yomhlabathi ingasetshenziselwa ukuvikela umswakama kanye nokufakwa kwezakhiwo ezakhiweni.
• I-Artificial Turf: Izinto ze-polyethylene zisetshenziswa kabanzi ekwenzeni i-artificial turf, enokuqina okuhle nobuhle.

Amathemba okuthuthukiswa kwezinto zokwakha i-polyethylene resin embonini yezokwakha ayathembisa, njengoba angahlangabezana nesidingo esikhulayo sokongiwa kwamandla, ukuvikelwa kwemvelo, kanye nentuthuko esimeme. Ngokuthuthukiswa okuqhubekayo kobuchwepheshe bokukhiqiza kanye nokuthuthukiswa kwezicelo ezintsha, izinto ze-polyethylene kulindeleke ukuthi zidlale indima ebaluleke kakhulu embonini yezokwakha.

Ukusetshenziswa kwe-polyethylene resin ku-powder coatings

I-polyethylene resin iya ngokuya isetshenziswa kabanzi kuma-powder coating. I-Powder coating iyi-organic engancibiliki, engaguquguquki enokuvikelwa kwemvelo, ukusebenza kahle okuphezulu, kanye nezinzuzo zokonga amandla. I-polyethylene resin iyinto ebalulekile yokusetshenziswa kwe-powder coating, ikakhulukazi esetshenziswa ezindaweni ezilandelayo:

• I-polyethylene resin ingasetshenziswa njengento eyinhloko yokwenza ifilimu ye-powder coatings, ngokunamathela okuhle, ukumelana nokugqoka, nokumelana nesimo sezulu, okungavikela ubuso bento eboshiwe ekugqwaleni kanye ne-oxidation.
• I-polyethylene resin ingasetshenziswa njenge-plasticizer ye-powder coatings, engathuthukisa ukuguquguquka kanye nokumelana nomthelela we-coating, okwenza ukunamathela kuhlale isikhathi eside.
• I-polyethylene resin ingasetshenziswa njenge-ejenti yokulinganisa ye-powder coatings, engathuthukisa ukucwebezela nokushelela kwendawo yokugqoka, okwenza ukunamathela kube kuhle kakhulu.
• I-polyethylene resin ingasetshenziswa njenge-antioxidant ye-powder coatings, enganweba impilo yesevisi ye-coating futhi ithuthukise ukuqina kwayo.

Kafushane, ukusetshenziswa kwe-polyethylene resin ezimbotsheni zempushana kungathuthukisa ukusebenza kanye nekhwalithi yokumboza, kuyilapho kuhlangabezana nezidingo zokuvikela imvelo kanye nethemba elibanzi lemakethe.
