Kev ua haujlwm tsis zoo ntawm cov hluav taws xob cua sov lub raj nplaum yog raws li hauv qab no

Hom polymer no suav nrog formaldehyde polymer, elastic polyurethane, thiab cov pa roj carbon dub, qhov tseem ceeb yog tias cov pa roj carbon dub no muaj tus nqi qis dua (kev nqus) thiab qhov loj me me piv rau cov pa roj carbon dub siv nyob rau hauv cov khoom sib xyaw kom deb li deb Kev txhim kho ntxiv ntawm Qhov chaw qis yog kev txhim kho ntawm cov khoom siv hluav taws xob ncaj qha. Cov yas conductive no tau tshwm sim thaum lub sij hawm sim ua haujlwm yuam kev. Qhov ntawd yog ib hnub nyob rau xyoo 1970, thaum xibfwb Shirakawa ntawm Tsukuba University hauv Nyij Pooj tau coj cov tub ntxhais kawm hauv kev sim los tsim cov polyacetylene siv cov roj ethylene, lawv ua yuam kev ntxiv cov khoom siv hluav taws xob 1000 npaug ntau dua li qhov xav tau tiag tiag rau cov reagent, thiab qhov tshwm sim tsis yog. qhov xav tau dub polyacetylene hmoov uas muaj cov pa roj carbon raws li ntev chains Nws yog ib tug ci iab nyiaj yas zaj duab xis. Tom qab ntawd, thaum kawm zaj duab xis yas no nrog ob tus neeg Asmeskas, Shirakawa pom tias ntxiv iodine rau hauv zaj duab xis tuaj yeem ua hluav taws xob tiag tiag, thiab cov khoom siv hluav taws xob tau nce 30 lab lub sijhawm. Txawm li cas los xij, nws cov conductivity tsuas yog sib npaug ntawm cov hlau lead, lossis IX ntawm tooj liab thiab nyiaj. Tom qab ntawd, tib neeg pib kawm cov yas conductive no.

Cov kev tshawb fawb tom qab tau pom tias, ntxiv rau polyacetylene, qee cov polymers siab molecular xws li polyphenylene sulfide, polypyrrole, Polythiophene thiab polythiazole kuj tuaj yeem ua cov yas yas tom qab ntxiv dopants. Raws li lub hauv paus no, tib neeg tau ua ib pawg ntawm cov polymers nrog conductivity sib npaug ntawm cov nyiaj thiab tooj liab, thiab hu ua lawv cov organic hlau lossis hlau hluavtaws.

Nrog rau txoj kev loj hlob sai ntawm cov cuab yeej siv niaj hnub no, tshwj xeeb tshaj yog qhov kev vam meej ntawm cov cuab yeej hluav taws xob niaj hnub no uas sawv cev los ntawm kev sib txuas lus thoob ntiaj teb hauv internet thiab kev sib txuas lus thoob ntiaj teb, nws ntseeg tau tias ib tiam tshiab ntawm cov khoom siv yas plated ncaj qha yuav raug tsim, vim qhov no twb yog kev lag luam ceev. xav tau. Qhov kev xav tau no yog lub zog tsav lub zog rau kev txhim kho thev naus laus zis.

Kev ua haujlwm tsis zoo ntawm cov nplaum nplaum yog raws li nram no: cov kab dej; Cua qauv. Cov nyhuv tom qab electroplating yog tias nws tseem pom meej meej tom qab electroplating, vim tias electroplating nws tus kheej muaj txheej nyias (2-30um), uas yog qhov nyuaj rau kev ua tiav los ntawm kev them nyiaj electroplating nkaus xwb.

Qhov tshwm sim ntawm cov khoom siv roj hmab puas yog batch ncov. Cov nyhuv tom qab electroplating yog tias cov txheej electroplating tseem khaws cia, uas tuaj yeem yooj yim ua rau khawb thiab cuam tshuam rau kev sib dhos.

Kev ua haujlwm tsis zoo ntawm cov nplaum nplaum yog: nplaum nplaum. Cov nyhuv tom qab electroplating yog tias nws tseem tsis tuaj yeem npog, cuam tshuam rau qhov tsos.

Kev ua haujlwm tsis zoo ntawm cov nplaum nplaum yog raws li hauv qab no: embossing / blistering. Cov nyhuv tom qab electroplating yog: foaming tom qab electroplating.

Kev ua haujlwm tsis zoo ntawm cov nplaum nplaum yog raws li hauv qab no: nplaum hlau / yas shavings. Cov nyhuv ntawm electroplating yog tias nws tsim cov hlau chips tom qab electroplating, uas cuam tshuam rau kev sib dhos thiab yooj yim puas tsuaj rau electroplating da dej tov.

Kev ua haujlwm tsis zoo ntawm cov khoom siv roj hmab yog raws li hauv qab no: kev sib tsoo / khawb. Cov nyhuv tom qab electroplating yog tias nws dhau los ua cov lus tshaj tawm thiab cuam tshuam rau cov tsos.

Kev ua haujlwm tsis zoo ntawm cov nplaum yog manifested li impurities. Cov nyhuv ntawm electroplating yog tias nws tuaj yeem ua rau cov xuab zeb, blistering, thiab to, cuam tshuam rau cov tsos.

Kev ua haujlwm tsis zoo ntawm cov nplaum yog manifested li shrinkage qhov. Cov nyhuv tom qab electroplating yog qhov yooj yim los nkaum cov tshuaj electroplating, uas cuam tshuam rau cov dej hauv lub tog raj kheej electroplating thiab ua rau plating plating ntawm lub workpiece.

Qhov tshwm sim ntawm qhov tsis zoo ntawm cov nplaum yog siv cov tshuaj tso tawm. Cov nyhuv tom qab electroplating yog tias nws yooj yim ua rau plating to, thiab lub zog sib txuas ntawm cov hlau plated tsis zoo, nrog cov roj stains.

Kev ua haujlwm tsis zoo ntawm qhov nplaum yog tshwm sim raws li cov khoom siv ntau dhau ntawm lub nozzle. Cov nyhuv tom qab electroplating yog tias nws yooj yim ua rau pitting, thiab plated qhov chaw yuav plating, ua rau tsis zoo adhesion. Qhov siab tshaj plaws ntawm cov khoom siv nozzle yuav tsum tsis pub tshaj 30 feem pua.

Kev ua haujlwm tsis zoo ntawm cov nplaum nplaum yog tshwm sim raws li cov pwm luam ntawv, cov cim cim, thiab rub cov cim. Cov nyhuv tom qab electroplating yog tias nws dhau los ua cov lus tshaj tawm thiab cuam tshuam rau cov tsos.

Matte corrosion kab ntawm electroplated qhov chaw: Lub thickness ntawm nto corrosion kab yuav tsum zoo ib yam, tshwj xeeb tshaj yog rau semi gloss chromium khoom. Yog tias cov kab xeb zoo zoo, yuav tsis muaj cov nyhuv matte.

Teeb tsa txoj haujlwm dai rau cov khoom siv hluav taws xob: Yog tsis muaj qhov tsim nyog dai, nws yooj yim rau deformation, thiab kev sib txuas tsis zoo ntawm qhov chaw thiab cov dej nozzles tuaj yeem ua rau tsis zoo tam sim no, ua rau yellowing thiab plating to.

Cov khoom muaj pes tsawg leeg ntawm electroplated qhov chaw: Electroplated qib ABS yog qhov zoo tshaj plaws, los yog ABS zoo tib yam siv tau. Cov khoom xyaw yuav tsum yog hom tshiab, thiab tsis muaj xim hmoov yuav tsum tau ntxiv.

Cov txheej txheem ntim rau cov khoom siv electroplated: Txoj kev nyiam yog siv ib lub thawv hlwv rau ntim, ua raws li ib txheej ntawm PE hnab. Cov khoom loj yuav tsum tau qhwv nrog cov ntaub paj rwb sab hauv thiab cov hnab npuas sab nraud.
