Xov xwm

Polylactic Acid (PLA) yog siv dav siv biodegradable polymer hauv kev lag luam xws li ntim, 3D luam ntawv, thiab textiles. Txawm li cas los xij, PLA yog qhov nkag siab zoo rau cov dej noo thiab cua sov, uas tuaj yeem cuam tshuam rau nws cov khoom siv kho tshuab thiab kev ua haujlwm zoo. PLA Crystallizer Dryer System ua lub luag haujlwm tseem ceeb hauv kev ua kom PLA tswj nws txoj kev ncaj ncees thiab zoo thaum lub sijhawm tsim khoom. Kev nkag siab txog qhov system no ua haujlwm li cas tuaj yeem pab cov tuam txhab tsim kho lawv cov txheej txheem ua haujlwm thiab txhim kho cov khoom lag luam.

Nkag siab PLA Crystallization thiab ziab
PLA yog ib qho amorphous polymer, txhais tau tias nws cov qauv molecular tsis muaj ib daim ntawv crystalline hauv nws lub xeev nyoos. Crystallization yog cov txheej txheem uas rov kho PLA cov molecules rau hauv ib daim ntawv ntau dua, txhim kho nws cov cua sov, lub zog, thiab kav ntev. Txawm li cas los xij, thaum lub sij hawm crystallization thiab kev ua haujlwm ntxiv, PLA kuj nqus dej noo los ntawm huab cua, uas tuaj yeem ua rau degradation, txo cov khoom siv kho tshuab, thiab kev ua haujlwm tsis zoo.
PLA Crystallizer Dryer System yog tsim los daws cov teeb meem no los ntawm ib txhij crystallizing thiab ziab PLA pellets lossis flakes, kom ntseeg tau tias lawv tsim nyog rau extrusion, molding, lossis 3D luam ntawv.

Cov ntsiab lus tseem ceeb ntawm aPLA Crystallizer tshuab ziab khaub ncawsQhov system
1. Crystallizer Unit
Chav tsev crystallizer yog lub luag haujlwm rau hloov amorphous PLA rau hauv lub xeev semi-crystalline. Cov txheej txheem no suav nrog:
• Tswj cua sov: PLA yog cua sov rau qhov kub thiab txias kom pib crystallization thaum tiv thaiv degradation.
• Agitation System: Cov khoom yog txuas ntxiv stirred los yog tumbled los tiv thaiv clumping thiab xyuas kom meej zoo crystallization.
• Tswj Kev Kub Kub: Kev tswj qhov kub thiab txias yog qhov tseem ceeb kom ua tiav qhov xav tau crystallinity yam tsis ua rau PLA degradation.
2. Tshuab ziab khaub ncaws
Thaum PLA yog crystallized, nws txav mus rau qhov ziab kom qhuav, uas tshem tawm cov dej noo ntau dhau los ua kom muaj kev ua haujlwm zoo ib yam. Cov txheej txheem drying muaj xws li:
• Dehumidified Air Flow: Ib qho kwj ntawm cov cua kub, tsis tshua muaj huab cua circulates los ntawm cov khoom, absorbing noo noo zoo.
• Nqus los yog Desiccant Drying: Qee lub tshuab siv lub tshuab nqus tsev los yog desiccant-based drying kom ua tiav cov dej noo tsawg.
• Kev soj ntsuam tas mus li: Sensors taug qab cov dej noo thiab qhov kub thiab txias kom tswj tau qhov ziab kom zoo.

Cov txheej txheem ua haujlwm li cas
Kauj Ruam 1: Xa cov khoom siv PLA
Raw PLA pellets, flakes, los yog granules yog loaded rau hauv crystallizer. Cov khoom siv feem ntau muaj cov dej noo siab, uas yuav tsum tau txo qis ua ntej ua haujlwm ntxiv.
Kauj Ruam 2: Cua sov thiab agitation
Lub kaw lus siv tswj cov cua sov thaum tsis tu ncua agitating cov khoom. Qhov no ua kom ntseeg tau tias txawm tias crystallization thiab tiv thaiv kev nplaum los yog clumping, uas yog ib qho teeb meem nrog PLA.
Kauj Ruam 3: Hloov mus rau Theem Qhuav
Tom qab ua tiav qhov xav tau crystallinity, cov khoom txav mus rau hauv lub tshuab ziab khaub ncaws, qhov chaw kub, dehumidified cua tshem tawm cov dej noo ntau dhau. Cov kauj ruam no yog qhov tseem ceeb los tiv thaiv hydrolytic degradation, uas ua rau PLA lub zog tsis muaj zog thaum lub sij hawm melting thiab shaping.
Kauj Ruam 4: Kev txo cov dej noo zaum kawg
Lub kaw lus txuas ntxiv kom qhuav kom txog thaum cov dej noo nce mus txog qhov zoo tagnrho rau kev ua, feem ntau qis dua 250 ppm (qhov ib lab). Thaum tag nrho qhuav, PLA yog npaj rau kev siv extrusion, txhaj tshuaj molding, thermoforming, los yog 3D luam ntawv.

Cov txiaj ntsig ntawm Kev Siv PLA Crystallizer Tshuab Tshuab
1. Txhim kho cua sov
Crystallized PLA tuaj yeem tiv taus qhov kub ua haujlwm ntau dua, ua rau nws tsim nyog rau kev txhaj tshuaj molding thiab kev siv kub.
2. Txo kev ua haujlwm tsis zoo
Los ntawm kev tshem tawm cov dej noo ntau dhau, lub kaw lus tiv thaiv npuas tsim, warping, thiab txhua yam tsis ua haujlwm thaum lub sijhawm tsim khoom.
3. Txhim kho cov cuab yeej cuab tam
Crystallized thiab kom qhuav PLA nthuav tawm lub zog zoo dua, ua haujlwm ntev, thiab ua haujlwm rau deformation.
4. Kev ua haujlwm tau sai dua
Nrog rau ib txhij crystallization thiab ziab, cov tuam ntxhab tuaj yeem ua PLA zoo dua, txo cov khoom pov tseg thiab poob sijhawm.

Xaus
PLA Crystallizer Dryer System yog qhov tseem ceeb rau kev txhim kho kev ua tau zoo, ua haujlwm ntev, thiab kev ua tiav ntawm PLA cov ntaub ntawv. Los ntawm kev ua tib zoo tswj crystallization thiab tshem tawm cov dej noo, qhov system no ua kom cov txiaj ntsig zoo hauv ntau yam kev tsim khoom. Kev nkag siab tias nws ua haujlwm li cas tso cai rau cov tuam txhab ua kom muaj txiaj ntsig zoo thiab cov khoom sib xws, ua rau PLA muaj ntau yam thiab txhim khu kev qha biopolymer rau kev siv.
