npuasNpuas yog ib qho ntawm PET preform tsis xws luag thiab feem ntau tshwm sim los ntawm cov dej ntws los yog cua thaum lub sij hawm molding txheej txheem. Lawv txo cov neeg kho tshuab lub zog thiab pob tshab ntawm preform, uas tuaj yeem cuam tshuam tsis zoo rau lub raj mis tshuab kev ua haujlwm thiab cov tsos ntawm cov khoom kawg.
-
Cov pob dubCov pob dub tshwm sim li cov impurities tsaus nti ntawm qhov chaw lossis sab hauv lub preform, feem ntau tshwm sim los ntawm cov khoom tsis huv, degraded PET resin, los yog cov khoom seem hauv cov khoom siv txhaj tshuaj molding. Cov teeb meem no cuam tshuam cov khoom zoo li thiab yuav qhia tau tias tsis muaj kev tsim khoom.
-
HazeHaze hais txog qhov poob ntawm pob tshab uas ua rau PET preforms pom huab lossis milky. Nws yog feem ntau cuam tshuam nrog cov khoom tsis txaus kom qhuav, ua haujlwm tsis raug, lossis cov khoom siv raw tsis zoo, txo qhov pom kev pom ntawm lub raj mis tiav.
-
DajYellowing tshwm sim thaum PET resin raug kub dhau los yog cua sov ntev thaum ua, ua rau cov khoom degradation. Dhau li cuam tshuam cov tsos, nws kuj tseem qhia tau tias txo cov khoom siv thiab txo cov khoom zoo tag nrho.
-
Burrs (Flash)Burrs, tseem hu ua flash, yog nyias txheej ntawm cov yas ntau dhau los ua ib ncig ntawm lub rooj vag lossis pwm parting kab. Lawv tuaj yeem cuam tshuam nrog kev tsim cov raj mis qis qis, xav tau kev ua tiav ntxiv, thiab nce nqi tsim khoom yog tias tsis tswj kom raug.
Dab tsi ua rau PET Preform Defects?
PET preform defects tuaj yeem tshwm sim ntawm ntau theem ntawm kev tsim khoom. Kev nkag siab txog lawv cov hauv paus ntsiab lus pab txhim kho cov khoom zoo, kev tsim khoom sib xws, thiab kev tsim khoom.
Qhov zoo ntawm PET resin cuam tshuam ncaj qha rau cov tsos thiab kev ua haujlwm ntawm cov khoom tiav tiav. Cov ntaub ntawv tsis huv, degraded, los yog cov khoom tsis sib xws tuaj yeem ua rau muaj qhov tsis xws li cov pob dub, kub hnyiab, thiab xim daj. Kev siv siab - zoo PET resin pab kom zoo dua pob tshab, lub zog, thiab kev ua haujlwm ruaj khov.
PET resin nkag tau yooj yim nqus dej los ntawm ib puag ncig ib puag ncig, ua kom qhuav qhov tseem ceeb ua ntej txhaj tshuaj molding. Kev ziab tsis txaus tso cai rau cov dej noo kom nyob twj ywm hauv cov khoom, ua rau muaj npuas, txo cov pob tshab, thiab cov khoom tsis muaj zog hauv cov khoom ua tiav preform.
Kev txhaj tshuaj molding tsis pub dhau-xws li qhov kub thiab txias, kev txhaj tshuaj siab, txhaj tshuaj ceev, tuav lub siab, thiab lub sijhawm txias- yuav tsum tau ua tib zoo tswj thoob plaws hauv kev tsim khoom. Kev teeb tsa tsis raug tuaj yeem ua rau yellowing, haze, burrs, dimensional instability, thiab lwm yam molding defects uas cuam tshuam rau ob qho tib si tsos thiab cov khoom ua tau zoo.
Qhov xwm txheej ntawm kev txhaj tshuaj pwm ua lub luag haujlwm tseem ceeb hauv kev txiav txim siab preform zoo. Hnav cov khoom pwm, thaiv lub tshuab ua pa, lossis cov khoom puas tuaj yeem tsim qhov tsis zoo thiab qhov tsis sib xws. Kev tshuaj xyuas pwm tsis tu ncua thiab kev tiv thaiv kev tiv thaiv pab tswj kev tsim khoom ruaj khov thiab cov khoom zoo ib yam.
Cov cuab yeej tsim khoom lag luam ntseeg tau yog qhov tseem ceeb rau kev tswj xyuas kev tsim khoom zoo ib yam. Lub tshuab tsis ruaj khov, kev tswj cov txheej txheem tsis zoo, lossis cov khoom siv hnav tuaj yeem ua rau muaj kev hloov pauv hauv molding kev ua tau zoo thiab ua rau muaj feem cuam tshuam ntau lawm. Cov cuab yeej siv niaj hnub ua ke nrog kev saib xyuas cov txheej txheem zoo pab txhim kho kev tsim khoom thiab txo cov nqi tsis raug.
Yuav Tiv Thaiv PET Preform Defects li cas
Kev tiv thaiv PET preform tsis xws luag yuav tsum tau ceev faj tswj cov ntaub ntawv, khoom siv, pwm, thiab ua tej yam kev mob nyob rau hauv tag nrho cov txheej txheem ntau lawm. Kev ua raws li cov kev coj ua hauv qab no pab txhim kho cov khoom sib xws thaum txo cov khoom pov tseg thiab cov nqi tsim khoom.
- Siv High-Quality PET Resin- Xaiv cov ntaub ntawv PET siab -purity PET los ntawm cov neeg muag khoom txhim khu kev qha kom txo tau cov kab mob sib kis thiab ua kom cov khoom zoo sib xws thoob plaws hauv kev tsim khoom.
- Tswj cov khoom ziab khaub ncaws- Qhuav PET resin nyob rau hauv kev pom zoo kub thiab lub sij hawm ua ntej molding. Kev tswj cov dej kom zoo yuav pab tiv thaiv cov npuas, hawb pob, thiab lwm yam dej noo- cuam tshuam txog qhov tsis xws luag.
- Optimize Txhaj Molding Parameters- Tsis tu ncua saib xyuas thiab kho cov txheej txheem ua haujlwm xws li kub, siab, txhaj tshuaj ceev, thiab lub sijhawm txias. Stable molding tsis txhim kho qhov tseeb qhov tseeb thiab txo cov khoom tsis xws luag.
- Khaws Moulds tsis tu ncua- Ntxuav, tshuaj xyuas, thiab kev pabcuam pwm tsis tu ncua kom ntseeg tau tias muaj qhov cua kom zoo, sib dhos kom raug, thiab cov kab noj hniav du. Zoo-cov pwm khaws cia ua rau cov khoom zoo sib xws thiab lub neej pwm ntev dua.
- Ua raws li kev soj ntsuam nruj nruj- Tsim cov txheej txheem tswj kev ua tau zoo thoob plaws hauv kev tsim khoom, suav nrog kev tshuaj xyuas cov khoom siv raw, hauv - kev soj ntsuam cov txheej txheem, thiab kuaj cov khoom tiav. Kev tshawb pom ntxov ntawm qhov tsis xws yuav pab txo cov khoom pov tseg thiab txhim kho kev tsim khoom.
