Nhau - Plastic Extrusion Machine Inoshanda Sei?

Plastic extrusion, inozivikanwawo seplasticating extrusion, inoramba ichiita yakakwira vhoriyamu yekugadzira maitiro umo thermoplastic zvinhu - muchimiro chehupfu, pellets kana granulates - inonyungudutswa zvine homogeneous yobva yamanikidzwa kubuda mukuumbwa kufa nenzira yekumanikidza. Muscrusion extrusion, kudzvanywa kunobva kune screw rotation yakatarisana nedhiramu madziro. Sezvo purasitiki inonyungudika ichipfuura nemufa, inowana iyo yekufa chimiro uye inosiya extruder. The extruded product is called extrudate.

Iyo yakajairika extruder ine nzvimbo ina:

Feed Zone

Munharaunda iyi, kudzika kwendege kunoramba kuripo. Chinhambwe chiri pakati pedhayamita hombe kumusoro kwendege uye dhayamita diki resiruu iri pasi pekubhururuka ndiko kudzika kwendege.

Transition Zone kana Compression Zone

Kudzika kwendege kunotanga kudzikira munzvimbo iyi. Muchokwadi, iyo thermoplastic zvinhu inomanikidzwa uye inotanga kuita plastiki.

Mixing Zone

Munharaunda iyi, kudzika kwendege kunoramba kuripo. Kuve nechokwadi chekuti zvinhu zvakanyungudutswa zvachose uye zvakasanganiswa zvakasanganiswa, chinhu chakakosha chekusanganisa chinogona kunge chiri munzvimbo.

Metering Zone

Iyi nzvimbo ine kudzika kwendege kudiki pane munzvimbo yekusanganiswa asi inoramba iripo. Zvakare, iyo dzvinyiriro inosundira kunyungudika kuburikidza nekuumbwa kufa munzvimbo ino.

Pane imwe pfungwa, kunyungudika kwemusanganiswa wepolymer kunokonzerwa nezvinhu zvitatu zvikuru:

Heat Transfer

Kutamisa kupisa isimba rinotamiswa kubva kune extruder mota kuenda kune extruder shaft. Zvakare, iyo polymer kunyunguduka inokanganisa screw profile uye nguva yekugara.
