Yuav ua li cas los tsim thiab zam cov kab cim hauv iav fiber ntau extruded khoom?
Factors ntawm kab cim hauviav fiber ntauCov khoom siv extruded:
Cov yam ntxwv uas yuav ua rau cov kab kos yog: lub qhov ncauj pwm, daim hlau perforated, cov ntsia hlau, cov khoom siv dai daim di ncauj, cov khoom siv hauv qab xws li caliper, lub tank dej txias, tsheb laij teb, thiab lwm yam. Qhov hluav taws xob ntawm qhov tuag (xws li kab cim tshwm sim los ntawm kev tuag tee), hauv qhov tuag (qhov chaw tsis zoo hauv qhov tuag lossis cov khoom dai hauv cov pwm tuag), cov dej ntws (hauv cov phaj ntxeem tau, cov ntxaij lim dej lossis cov ntsia hlau). Cov xov tooj ntawm tus kheej feem ntau yog tsim nyob rau hauv txoj cai-angled lub qhov ncauj pwm. Thaum cov kab cim tau tshwm sim los ntawm qhov ncaj-dhau tuag, tus naj npawb ntawm cov kab cim yuav phim tus naj npawb ntawm cov hlua khi. Perforated daim hlau tuaj yeem ua rau ntau tus xov tooj hauv kab lus. Cov xov tooj tseem tuaj yeem tuaj yeem nqes los ntawm lub qhov ncauj pwm, tshwm sim los ntawm cov khoom sib cuag nrog cov khoom extruded, los yog tshwm sim los ntawm qhov chaw txias los yog kub. Cov teeb meem no feem ntau yooj yim rau kev kuaj mob los ntawm kev soj ntsuam qhov twg cov kab cim tshwm sim thaum lub sij hawm extrusion txheej txheem.
Vuam cov cim hauv iav fiber ntau extruded khoom
Weld marks: Kab cim nyob rau hauv cov khoom extruded tej zaum yuav los ntawm weld kab. Cov cim weld no yog tsim thaum lub polymer yaj cais thiab rov fuses nyob rau hauv lub qhov ncauj tuag los yog txawm nyob rau hauv pem hauv ntej ntawm lub qhov ncauj tuag. Weld kab tseem hu ua confluence marks; Cov kab cim no tuaj yeem tsim nyob rau hauv lub hose thiab raj lub qhov ncauj pwm qhov twg cov pwm tseem ceeb tau txais kev txhawb nqa los ntawm cov tav ntawm lub bracket. Lub polymer yaj yog sib cais thaum pib ntawm lub bracket tav thiab ntws ua ke dua tom qab lub bracket. Vim muaj qhov txwv tsis pub txav ntawm cov macromolecules polymer, nws yuav siv sij hawm rau cov molecules rov qab. Cov txheej txheem ntawm rewinding no tseem hu ua "rov qab" txheej txheem. Qhov ntev ntawm cov molecule, nws yuav siv sij hawm ntev rau rewind. Yog li ntawd, siab molecular hnyav (high viscosity) polymers yog feem ntau ua rau vuam cov qhab nia tshaj qhov hnyav molecular (tsawg viscosity) polymers.
Cov yam tseem ceeb uas txiav txim siab qhov teeb meem ntawm cov kab weld yog: qhov ntev ntawm lub sij hawm (lub sij hawm nyob) los ntawm cov yaj streamline mus rau qhov hluav taws xob tuag; Lub sijhawm rau polymer yaj rov qab. Yog hais tias lub sij hawm nyob rau hauv lub sij hawm ntev dua lub sij hawm rov qab, cov weld kab yuav ploj mus rau hauv lub qhov ncauj pwm thiab yuav tsis muaj teeb meem ntawm cov khoom extruded. Txawm li cas los xij, yog tias lub sijhawm nyob hauv lub sijhawm luv dua lub sijhawm rov qab los, cov kab vuam yuav tsis ploj mus rau qhov tuag thiab cov kab vuam yuav ua rau muaj teeb meem ntawm cov khoom extruded. Los ntawm kev ua kom lub sij hawm nyob hauv lub qhov ncauj pwm los yog txo lub sij hawm rov qab los ntawm cov polymer yaj, qhov teeb meem ntawm cov kab weld tuaj yeem txo lossis tshem tawm.
