Nws lub luag haujlwm tseem ceeb yog kom xaus qhov plastics nrog kev coj ua lossis tshuaj tiv thaiv hluav taws xob, ua rau lawv muaj kev lag luam, ntim rau cov khoom ua haujlwm ntawm cov ntaub ntawv.
2. Kev faib tawm ntawm kev coj ua tau zoo masterbatches
Raws li cov fillers sib txawv, kos cov masterbatches tuaj yeem yog faib rau hauv cov khoom lag luam hauv qab no:
Cov pa roj carbon-raws li cov masterbatch: Siv carbon dub, carbon fibene, nws muaj tus nqi qis dua thiab haum rau feem ntau cov cai tshuaj lom neeg thiab dav dav.
Hlau-based conductive masterbatch: nws siv cov hlau ua ke xws li nyiaj hmoov, tooj liab hmoov lossis npib tsib poob. Nws muaj kev ua tau zoo heev, tab sis tus nqi yog qhov siab. Nws yog tsuas yog siv nyob rau hauv high-kawg hauv hluav taws xob thiab hluav taws xob tiv thaiv teb.
Composite conductive masterbatch: sib txuas ntau yam kev ua haujlwm rau cov chaw ua haujlwm, nws ua kom zoo tshaj plaws cov khoom lag luam thiab kev ua tau ruaj khov, thiab tsim nyog rau cov ntawv thov tshwj xeeb.
3. Cov kev ua tau zoo ntawm kev coj ua ntawm masterbatch
Cov ntsuas tseem ceeb ntawm cov ntsiab lus tseem ceeb ntawm kev coj ua ke ntawm cov masterbatch muaj xws li:
Conductivity:Nws yog feem ntau ntsuas los ntawm cov ntim resistivity, nrog cov ntau xws li los tiv thaiv cov qub (10⁶ txog 10 ω ω ω ω ω⁹) (((10⁶⁹⁹⁹⁹⁹⁹⁹⁹⁹⁹ (() rau kev ua haujlwm siab (< 10² Ω·cm).
Dispersion:Cov qib ntawm cov kev faib tawm ntawm cov muab tub lim rau hauv lub cob, uas cuam tshuam rau hluav taws xob kev coj ruaj khov thiab cov tsos ntawm cov khoom kawg.
Ua cov khoom yoog tau: nws yuav tsum sib haum nrog ntau yam plastics (xws li PP, PE, ABS, thiab lwm yam) kom paub meej tias kev txhaj tshuaj zoo thaum lub sij hawm txhaj tshuaj molding, extrusion, thiab lwm yam txheej txheem.
4. Daim Ntawv Thov Cov Khoom Siv Kev Ua Haujlwm Masterbatch
Ces xeeb capbatch yog dav siv nyob rau hauv ntau yam kev lag luam:
Khoom Siv Hluav Taws Xob:Siv rau IC cov tais, ntim ntawm cov hluav taws xob hluav taws xob, cov keyboard thiab cov xwm txheej, kom tsis txhob muaj kev puas tsuaj elottrostatic.
Kev Lag Luam Automotive:Siv rau cov khoom siv ntawm cov roj tshuab thiab roj teeb plhaub rau kev siv hluav taws xob tshiab, muaj peev xwm ua rau muaj kev nyab xeeb thiab tiv thaiv kev sib cuam tshuam.
Kev tawg-ntawv pov thawj:Siv nyob rau hauv cov xwm txheej uas yog qhov hluav taws xob hluav taws xob zoo li cas, xws li hauv cov khoom siv mining thiab cov kav dej chemical, kom txo qis kev pheej hmoo ntawm kev tawg.
Kev Lag Luam Ntim:Kev lag luam siab rau kev lag luam xws li tshuaj thiab tub rog, los tiv thaiv hluav taws xob zoo li qub los yog kev cuam tshuam cov khoom siv thev naus laus zis.
5.Qhov kev tsim kho thev naus laus zis ntawm kev coj ua tau zoo masterbatches
Cov lus qhia yav tom ntej kev txhim kho ntawm cov masterbatches suav nrog:
Tsawg-sau cov tshuab siv tshuab hluav taws xob siab:Los ntawm kev ua kom zoo rau cov fiber (xws li cov nanotubes, graphene), tus nqi ntawm cov muab tub lim ntxiv tuaj yeem txo thaum tswj lub siab.
Multifunctional kev sib xyaw ua ke:Sib txuas nrog conductive, nplaim taws-retardant, thiab cov tshuaj tua kab mob tua kom tau raws li cov kev yuav tsum tau ua tiav ntau dua.
Kev tiv thaiv ib puag ncig:Txhim kho biodegradable substrates thiab halogen-dawb nplaim-retardant system-retardant, hauv kab nrog ntsuab tsim qauv.
6. Kev Nyuaj Siab thiab Cov zeem muag
Txawm hais tias lub khw muag khoom granule granule muaj qhov dav dav yav tom ntej, nws tseem ntsib qee qhov kev cov nyom:
Technical bottleneck:Cov teeb meem xws li qhov sib npaug ntawm kev ua haujlwm siab thiab kev ua tiav, nrog rau kev ruaj ntseg ntawm cov dispersion ntawm nanofillers, tseem yuav tsum tau kov yeej.
Tus nqi siab:Cov nqi ntawm cov chav high-enders (xws li nyiaj hmoov thiab carbon nanotubes) yog qhov tseem ceeb, uas cuam tshuam lawv cov ntawv thov loj.
Cov Qauv Ua Tau:Cov kev ntsuas kev lag luam thiab cov qauv kev kawm tseem tsis tau tsim kev tsim tawm tag nrho, uas cuam tshuam rau cov khoom lag luam zoo.
Nrog rau kev loj hlob sai ntawm kev lag luam xws li 5g, lub zog tshiab, thiab muaj tswv yim hluav taws xob, kev lag luam lag luam rau cov granules granules tseem yuav loj hlob ntxiv. Yav tom ntej, kev ua tau zoo, tus nqi qis, thiab ib puag ncig cov phooj ywg granules hauv kev lag luam, kev tsav tsheb txuas ntxiv hauv kev hloov kho cov yas.
