Basic ihe ọmụma nkeplastic extrusion usoro
Usoro extrusion plastik ga-amalite site n'ịgbanwe resin raw. Nke mbụ, tinye ya na hopper nke extruder. Mgbe resin enweghị ihe mgbakwunye maka ụfọdụ ngwa a kapịrị ọnụ, a na-agbakwunye ihe mgbakwunye na hopper. Mgbe etinyechara ya, a na-enye resin ahụ nri site na ọdụ ụgbọ mmiri nke hopper, wee banye na gbọmgbọm nke extruder. Enwere mkpọsa na-atụgharị na gbọmgbọm ahụ. Nke a ga-eri nri resin, nke ga-eme njem n'ime ogologo gbọmgbọm.
N'oge usoro a, resin na-ekpughere okpomọkụ dị elu. Oke okpomọkụ nwere ike gbazee ihe. Dabere na okpomọkụ gbọmgbọm na ụdị thermoplastic, okpomọkụ nwere ike ịdị iche site na 400 ruo 530 degrees Fahrenheit. Na mgbakwunye, ọtụtụ extruders nwere gbọmgbọm nke na-eme ka okpomoku dị elu site na ntinye ruo na nri ruo na-agbaze. Usoro dum na-ebelata ihe ize ndụ nke mmebi plastik.
Plastic ga-agbaze ma rute na njedebe nke gbọmgbọm ahụ, ebe a ga-agbanye ya na tube nri site na nzacha ma mesịa nwụọ. N'oge usoro mkpochapụ, a ga-eji enyo wepụ ihe ndị na-emerụ emerụ na rọba a wụrụ awụ. Ọnụ ọgụgụ nke ihuenyo, porosity nke ihuenyo na ụfọdụ ihe ndị ọzọ na-achịkwa iji hụ na agbaze otu.
