Ntawm ntau hom yas pwm, PET preform pwm yog suav tias yog ib pawg tshwj xeeb vim lawv cov qauv tsim tshwj xeeb thiab cov txheej txheem ua haujlwm. PET preforms yog siv dav hauv ntim khoom noj, tshuaj pleev ib ce, tshuaj, thiab lwm yam lag luam. Cov pwm tsim thiab cov txheej txheem tsim khoom ncaj qha cuam tshuam qhov zoo ntawm cov khoom kawg thiab kev ua haujlwm ntau lawm. Tsab ntawv xov xwm no yuav qhia txog qhov tseem ceeb hauv kev tsim thiab tsim PET preform pwm thiab tshawb xyuas seb yuav ua li cas txhawm rau txhawm rau txhaj tshuaj molding txheej txheem tuaj yeem ua kom cov khoom zoo ntawm - zoo PET preforms.
Cov yam ntxwv thiab kev ua haujlwm ntawm cov khoom siv PET
Cov ntaub ntawv PET muaj cov ntsiab lus siab melting thiab muaj zog hygroscopic, uas txhais tau hais tias lawv yuav tsum tau tswj nruj dua kub thiab av noo thaum txhaj tshuaj molding. PET cov qauv loj molecular muaj cov pab pawg rog, uas yog rhiab heev rau cov dej noo, thiab cov dej noo ntau dhau tuaj yeem txo qhov hnyav molecular, ua rau tsis muaj xim lossis brittleness ntawm cov khoom molded. Yog li, ua ntej txhaj tshuaj molding, PET granules yuav tsum tau ua kom qhuav, feem ntau ntawm 150℃rau tsawg kawg yog 4 teev, nrog rau qhov kub ntau tshaj plaws yog 170℃rau 3-4 teev. Qhov kev faib ua feem ntawm cov khoom siv rov ua dua tshiab yuav tsum tsis pub tshaj 25% kom ntseeg tau cov khoom zoo.
Kev xaiv cov tshuab txhaj tshuaj molding
Kev xaiv ntawm kev txhaj tshuaj molding tshuab yog qhov tseem ceeb rau kev ua kom zoo ntawm PET preform pwm. Muab lub siab melting point thiab lub sij hawm luv luv ntawm PET, nws yog ib qho tseem ceeb uas yuav tsum tau siv lub tshuab txhaj tshuaj molding nrog kev tswj qhov kub thiab txias thiab qis tus kheej - kev sib txhuam thaum lub sij hawm plasticization. Lub tshuab txhaj tshuaj molding yuav tsum muaj ntau qhov chaw tswj qhov kub thiab txias thiab muaj peev xwm tswj tau qhov kub thiab txias thaum txhaj tshuaj. Tsis tas li ntawd, qhov hnyav ntawm cov khoom txhaj tshuaj, suav nrog cov neeg khiav dej num, yuav tsum tsis pub tsawg dua ob -feem peb ntawm lub tshuab txhaj tshuaj lub peev xwm txhaj tshuaj.
Kev xaiv Robot Arms thiab Load Requirements
Hauv kev tsim cov khoom siv hluav taws xob ntawm PET preforms, kev xaiv cov neeg hlau caj npab ua lub luag haujlwm tseem ceeb hauv kev ua kom ruaj khov thiab ua tau zoo preform tshem tawm. Feem ntau siv neeg hlau caj npab rau PET preform pwm yog peb -axis overhead qhib- hom neeg hlau caj npab. Cov caj npab neeg hlau no tuaj yeem tshem tawm cov preforms ntawm kev kub ceev thiab raug muab tso rau lawv. Thaum xaiv neeg hlau caj npab, tshwj xeeb yuav tsum tau them rau lub peev xwm thauj khoom thiab caj npab rigidity. Rau cov pwm loj PET preform, xws li cov uas muaj 48 lossis 72 kab noj hniav, nws raug nquahu kom siv siab - lub zog ob - tsheb nqaj hlau neeg hlau caj npab nrog lub peev xwm thauj khoom tsawg kawg 15kg.
Pwm Tsim thiab Gate Configuration
Cov pwm tsim rau PET preforms ncaj qha cuam tshuam qhov tshwm sim molding. Kub khiav pwm feem ntau yog siv rau PET preforms, uas pab txo cov khib nyiab thaum lub sij hawm txhaj tshuaj thiab txhim kho kev tsim khoom. Txhawm rau kom ntseeg tau tias qhov ntsuas kub tsis sib xws thoob plaws cov pwm, cov cua sov- cov phaj insulating raug ntsia nruab nrab ntawm cov pwm thiab cov tshuab txhaj tshuaj molding platen. Cov tshav kub no-cov phaj insulating yuav tsum yog 12mm tuab thiab muaj peev xwm tiv taus siab - cov xwm txheej siab. Tsis tas li ntawd, cov pwm lub qhov cua tshuab yog qhov tseem ceeb kom tsis txhob muaj cua sov hauv cheeb tsam lossis preform tawg. Lub qhov tob yuav tsum tsis pub tshaj 0.03mm los tiv thaiv flash tsim.
Tswj kev txhaj tshuaj molding kub
Kev tswj kub thaum txhaj tshuaj molding yog qhov tseem ceeb rau qhov zoo ntawm PET preforms. Lub melting kub rau tus qauv PET feem ntau yog nyob nruab nrab ntawm 270-295 degree, thaum rau iav - puv GF-PET, qhov kub ntau yog 290-315℃. Kev txhaj tshuaj ceev kuj tseem yuav tsum tau tswj nyob rau hauv ib qho kev tiv thaiv kom tsis txhob muaj kev sib tsoo ntawm preform thaum lub sij hawm txhaj tshuaj. Txawm li cas los xij, kev txhaj tshuaj ntau dhau tuaj yeem ua rau lub siab shear npaum li cas, uas yuav ua rau lub preform ua nkig. Nws yog ib qho tseem ceeb kom ua tiav cov txheej txheem txhaj tshuaj tsis pub dhau 4 vib nas this kom tsis txhob muaj teeb meem zoo.
Back Pressure Control thiab Residence Time
Kev tuav lub siab rov qab yog qhov tseem ceeb hauv kev txhaj tshuaj molding ntawm PET preforms kom txo qis hnav thiab tsim kua muag ntawm lub tshuab. Rov qab siab yuav tsum feem ntau tsis tshaj 100 bar. Tsis tas li ntawd, nws yog ib qho tseem ceeb kom tsis txhob muaj lub sij hawm nyob ntau dhau, vim tias qhov ntev ntev ntawm qhov kub thiab txias tuaj yeem ua rau txo qis hauv molecular hnyav thiab cuam tshuam rau lub zog thiab pob tshab ntawm preform. Yog tias lub tshuab tsis ua haujlwm tsawg dua 15 feeb, lub voj voog txhaj tshuaj tas li txaus los ntxuav lub cev. Txawm li cas los xij, yog tias lub tshuab tsis ua haujlwm ntev dua 15 feeb, PE nrog cov viscosity siab dua yuav tsum tau siv los ntxuav, thiab lub thoob kub yuav tsum tau txo qis rau PE ua haujlwm kub ua ntej rov pib dua.
Kev txiav txim siab ntxiv
Ntxiv rau qhov tseem ceeb uas tau teev tseg saum toj no, ntau cov ntsiab lus xav tau kev saib xyuas tshwj xeeb. Ua ntej, qhov kev faib ua feem ntawm cov khoom siv rov ua dua yuav tsum tsis txhob siab dhau, vim tias cov khoom siv rov qab ntau dhau tuaj yeem ua rau "bridging" ntawm cov khoom noj khoom haus, cuam tshuam rau cov txheej txheem plasticizing. Qhov thib ob, cov pwm tsis zoo lossis cov khoom siv ntsuas kub tuaj yeem ua rau "dawb pos huab" ntawm qhov chaw ntawm preform, txo nws cov pob tshab. Yog li ntawd, nws yog ib qho tseem ceeb los xyuas kom meej tias cov pwm kub yog tswj uniformly, thiab tus nqi txias yog tsim nyog los txhim kho lub pob tshab ntawm preform. Thaum kawg, lub rigidity thiab load- bearing peev xwm ntawm tus neeg hlau caj npab ncaj qha cuam tshuam rau stability ntawm lub preform tshem tawm txheej txheem. Yog hais tias tus neeg hlau caj npab tsis muaj rigidity los yog txaus load peev xwm, nws yuav ua rau instability nyob rau hauv cov txheej txheem tshem tawm thiab txo tus neeg hlau caj npab lifespan.
