Sib cais cov ntsia hlau ntawm extruder rau yaj-blown daim ntaub tshuab

Ib qho kev pabcuam xov ntxiv yog ntxiv rau hauv ntu compression, uas kov yeej qhov tsis txaus los ntawm kev sib koom ua ke ntawm cov khoom txaj thiab cov yaj hauv cov ntsia hlau groove hauv cov qauv ntsia hlau. Cov khoom molten thiab cov khoom uas tsis tau yaj yog sib cais kom sai li sai tau, yog li txhawb lub melting ntawm cov khoom unmelted.

Cov ntsia hlau no muaj kev ua haujlwm siab plasticizing thiab zoo plasticizing zoo. Txij li thaum tsis muaj kev puas tsuaj ntawm lub txaj khoom, qhov kev hloov pauv ntawm cov zis, siab thiab qhov kub thiab txias yog qhov me me, thiab muaj qhov zoo ntawm kev ua haujlwm zoo ntawm cov pa tawm thiab kev siv hluav taws xob tsawg, thiab tau siv dav.
