Amanyathelo eNkqubo yePlastiki Extrusion
Xa ndikhokela umntu nge inkqubo yeplastiki extrusion, Ndihlala ndiyichitha icace, amanyathelo alawulekayo. Oku inkqubo inyathelo ngenyathelo iguqula iipeliti zeplastiki ekrwada zibe yimveliso egqityiweyo ngokuchaneka nangempumelelo. Nantsi indlela endisondela ngayo kwinqanaba ngalinye:
Ukutya iiPellets
Ndiqala inkqubo yeplastiki ye-extrusion ngokukhetha i uhlobo oluchanekileyo lweepeliti zeplastiki. Ukukhethwa kwezinto eziphathekayo kuba uhlobo ngalunye luzisa iimpawu ezizodwa kwimveliso yokugqibela. Umzekelo, Ndihlala ndisebenzisa i-polyethylene ngenxa yobunzima bayo kunye nokumelana neekhemikhali, i-polystyrene ngenxa yokuqina kunye nokucaca kwayo, okanye i-polypropylene ngenxa yamandla ayo kunye nenqanaba eliphezulu lokunyibilika. Ndigalela ezi pellets kwi hopper, ezizondla kwi-extruder. I-hopper iqinisekisa ukuhamba okuzinzileyo, ngoko ke inkqubo ihlala iqhubekile kwaye isebenza kakuhle.
Ingcebiso: Ndihlala ndijonga ukucoceka kunye nomgangatho weplastiki eluhlaza ngaphambi kokuba ndiqale. Umgangatho wezinto eziphathekayo uyandinceda ukuba ndiphephe iziphene kamva kwi-extrusion.
Nantsi ngokukhawuleza ukuthelekiswa kweepelisi zeplastiki eziqhelekileyo ndisebenzise:
