Kev ncua lub neej ntawm kev kho mob txhaj tshuaj molding kub khiav tshuab yuav tsum tau ua tib zoo saib rau plaub yam: kev ua haujlwm zoo, kev saib xyuas tsis tu ncua, kev tswj ib puag ncig, thiab cov khoom siv sib xws. Los ntawm kev tswj xyuas kom zoo, lawv lub neej ntev tuaj yeem txuas ntxiv mus rau 5-10 xyoo lossis tshaj 1 lab lub voj voog.
1. Standardize Pib- nce thiab kaw cov txheej txheem kom tsis txhob muaj cua sov
Preheating: Siv segmented cua sov (piv txwv li, nce los ntawm 50℃txhua 30 feeb), thiab tswj qhov kub thiab txias rau 30 feeb tom qab ncav cuag qhov kub thiab txias kom ntseeg tau tias cov cua sov sib txawv.
Txias Txias: Tom qab txhaj tshuaj, ua "txheej txheem tu" los ntawm kev yaug tus khiav nrog qis - viscosity PP cov ntaub ntawv, tom qab ntawd maj mam txias kom qis dua 80℃ua ntej tso tawm kom tsis txhob muaj kev ntxhov siab sab hauv uas tuaj yeem ua rau tawg.
2. Kev tu thiab tshuaj xyuas cov khoom tseem ceeb
Ua kom tiav disassembly thiab tu txhua txhua 500,000 cycles lossis 6 lub hlis: Siv ultrasonic lossis fluidized txaj tu los ntxuav lub phaj kub khiav thiab lub nozzles kom tshem tawm cov pa roj carbon deposits; Ua tib zoo saib xyuas tshwj xeeb rau kev ntxuav lub koob valve thiab lub rooj zaum ntawm lub rooj sib txuas ntawm cov koob valve kom tiv thaiv cov khoom me me los ntawm kev daig.
Yuav tsum tau hloov cov ntsaws ruaj ruaj: O-rings thiab sealing rings yuav tsum tau hloov txhua 1 lab pwm cycles los tiv thaiv kev laus thiab to.
Coaxiality Check: Lub nozzle thiab sprue lub tes tsho sib txawv yuav tsum tsawg dua los yog sib npaug rau 0.05mm los tiv thaiv kev hnav los ntawm thermal expansion.
3. Precise Temperature Control and Electrical System Maintenance:
Thermocouple Calibration: Kuaj txhua 3 lub hlis kom paub meej qhov ntsuas kub ntawm txhua cheeb tsam tsawg dua lossis sib npaug rau ± 1 degree.
Heating Coil Resistance Test: Hloov tam sim yog qhov sib txawv tshaj ± 10% kom tsis txhob muaj cua sov hauv zos.
Insulation Resistance Test: The insulation resistance of the conductor to ground should be >10MΩ txhawm rau tiv thaiv luv luv hauv qhov chaw ntub dej.
Pom zoo: Siv qhov ntsuas kub tswj qhov ntse (xws li Altanium®) uas txhawb nqa lub tswb tsis siv neeg thiab cov ntaub ntawv kaw rau kev taug qab tsis zoo.
4. Cov khoom siv thiab txheej txheem hloov kho kom zoo
Zam kev ua haujlwm ntev - lub sijhawm ua haujlwm siab - cov ntaub ntawv hnav: Cov ntaub ntawv uas muaj cov iav fiber ntau / cov khoom siv ntxhia (xws li PP + GF) ua rau muaj kev cuam tshuam loj ntawm cov dej ntws; Nws raug pom zoo kom txo lub voj voog txij nkawm mus rau 300,000 cycles.
Tswj kev txhaj tshuaj siab: Lub siab ntau dhau yuav ua rau kom qaug zog ntawm cov qauv sealing; nws yuav tsum tau khaws cia nyob rau hauv lub system tsim ntau yam.
Xaiv qis-shear internally heated nozzles: Haum rau cov cua sov- cov ntaub ntawv rhiab heev xws li PC thiab PMMA, txo qhov kev pheej hmoo ntawm degradation thiab txuas ntxiv cov ntws channel tu lub voj voog.
