Yuav ua li cas rau Customize Conductive Roj Hmab nrog txawv Conductivity theem

Hauv kev tsim khoom siv hluav taws xob, kev tsim hluav taws xob aerospace, thiab kev tiv thaiv kab mob, cov txheej txheem insulating roj hmab tsis txaus. Cov kws tshaj lij qhia cov khoom siv roj hmab kom ua tiav cov khoom siv hluav taws xob tshwj xeeb, txawm tias muab hluav taws xob hluav taws xob (ESD) kev nyab xeeb, tsim cov khoom siv hauv av, lossis cov khoom sib khi hauv txee los thaiv electromagnetic cuam tshuam (EMI).

Customizing conductive roj hmab yog qhov sib npaug ntawm cov khoom siv science thiab mechanical engineering. Kev kho hluav taws xob conductivity tsis yog tsuas yog txo qis kev tiv thaiv; nws yuav tsum ntsuas hluav taws xob kev ua tau zoo nrog kev txwv kev siv tshuab, cov khoom siv sib xws, thiab cov nqi tsim khoom. Hauv phau ntawv qhia no, peb rhuav tshem cov ntsiab lus tseem ceeb uas tswj xyuas cov roj hmab tiv thaiv thiab yuav ua li cas kho lawv rau koj daim ntawv thov.

1. Qhov tseem ceeb Engineering Factors uas txiav txim siab Rubber Conductivity

Cov roj hmab uas tsis tau hloov kho yog qhov uas tsis yog - conductive. Txhawm rau hloov hluav taws xob tam sim no lossis thaiv EMI, cov xov tooj hluav taws xob yuav tsum tau muab sib xyaw rau hauv elastomer siv cov khoom tshwj xeeb thiab cov txheej txheem txheej txheem:

• 1. Hom Conductive Fillers:Kev xaiv ntawm cov muab tub lim yog qhov tseem ceeb ntawm kev tsav tsheb hluav taws xob thiab kev ua haujlwm ntawm tus nqi. Common conductive additives muaj xws li:
  - Cov pa roj carbon dub (cov qib kev coj ua):Tus nqi- zoo, siv los tiv thaiv- zoo li qub thiab ESD- cov khoom nyab xeeb.
  - Graphite & Carbon Fiber:Nruab nrab conductivity thiab tsis hnyav.
  - Nickel & Silver -Coated Aluminium:Kev ua tau zoo heev, lub hauv paus rau siab -kev ua tau zoo B2B EMI gaskets.
  - Pure Silver Powder:Qhov siab tshaj plaws hluav taws xob conductivity, tab sis tus nqi siab.
  General Performance Rule:Nyiaj> Nyiaj-Coated Aluminium> Nickel> Graphite> Carbon Dub. Kev ua tau zoo ntawm hluav taws xob ncaj qha nce nqi raw khoom.
• 2. Filler Loading Ratio (Lub Percolation Threshold):Txhawm rau ua hluav taws xob, cov khoom siv hluav taws xob yuav tsum tau kov lub cev hauv cov roj hmab kom tsim txoj hauv kev txuas mus ntxiv (percolation). Ua kom cov khoom ntim ntxiv (piv txwv li, los ntawm 10% mus rau 30%) txo qhov ntim ntawm cov khoom tiv thaiv thiab ua kom cov conductivity. Txawm li cas los xij, cov khoom ntim ntau dhau ntawm cov neeg coob coob tawm ntawm cov saw hlau polymer, txo lub zog tensile, nce hardness, thiab ua tiav cov foob pob.
• 3. Base Elastomer Xaiv:Txawv elastomers txais thiab faib cov khoom siv hluav taws xob sib txawv.Silicone Roj Hmab (VMQ)yog tus neeg nqa khoom nyiam vim tias nws cov pob txha hloov tau yooj yim molecular tso cai rau cov khoom siv sib txuas ua kom yooj yim nrog kev ua haujlwm tsawg kawg nkaus. EPDM, NBR, thiab FKM kuj tau hloov kho rau ib puag ncig tshwj xeeb uas yuav tsum muaj roj, roj, lossis tshuaj tiv thaiv.
• 4. Elastomer Hardness (Durometer):Hardness plays lub luag haujlwm hloov maj mam hauv kev sib cuag. Softer conductive compounds (50 mus rau 60 Shore A) tso cai rau cov roj hmab kom ua tau yooj yim nyob rau hauv clamping quab yuam, ua kom muaj kev sib cuag saum npoo thiab txo qis kev tiv thaiv. Cov ntaub ntawv nyuaj dua tuaj yeem pom qhov ua haujlwm siab dua me ntsis vim yog qhov tawv tawv mating.
• 5. Compression Rate (Squeeze):Nyob rau hauv compression, cov conductive hais nyob rau hauv cov roj hmab yog nias los ze zog ua ke, nce kev sib cuag ceev. Yog li ntawd, feem ntau EMI gaskets thiab grounding pads pom cov hluav taws xob qis dua thaum compressed (hauv -siv lub xeev) piv rau lawv lub xeev so, uninstalled.
• 6. Environmental Factors (Kub & Kev Laus):Kev khiav hauj lwm kub hloov tsis kam raws li thermal expansion hloov qhov sib thooj ntawm cov khoom siv hluav taws xob. Tsis tas li ntawd, ib puag ncig kev laus los ntawm UV teeb, ozone, thiab cua sov ua rau cov saw hlau polymer, uas tuaj yeem ua rau cov khoom siv hluav taws xob sib cais, ua rau muaj kev tiv thaiv lub sijhawm.

Kev siv hluav taws xob siv hluav taws xob: Volume Resistivity los ntawm Compound

Thaum tsim qhov kev cai, qhia qhov tseeb **Volume Resistivity ( ntsuas hauv Ohm -centimeters, Ω·cm)** yog qhov tseem ceeb. Cov lus hauv qab no qhia txog cov hluav taws xob resistivity spectrum ntawm cov kev cai sib xyaw ua ke:
