Graphite hmoov yog kub hauv kev lag luam teb, thiab nws ua lub luag haujlwm loj hauv ntau qhov chaw. Ua ntej, nws tau hais ntau zaus tias graphite hmoov yog cov tshuaj zoo tshaj plaws los tiv thaiv corrosion ntawm cov khoom siv, thiab ntau tus neeg siv khoom tsis paub vim li cas. Niaj hnub no, tus editor ntawm Furuite Graphite yuav piav qhia meej vim li cas koj hais qhov no:
Kev ua tau zoo ntawm graphite hmoov ua rau nws yog qhov kev daws teeb meem zoo tshaj plaws los tiv thaiv cov khoom siv corrosion.
1. Resistant rau tej yam kub. Kev siv kub ntawm graphite hmoov yog nyob ntawm cov khoom siv impregnating, xws li phenolic resin impregnated graphite tuaj yeem tiv taus 170-200 ℃, thiab yog tias muaj qhov tsim nyog ntawm silicone resin impregnated graphite ntxiv, nws tuaj yeem tiv taus 350 ℃. Thaum phosphoric acid tso rau ntawm carbon thiab graphite, oxidation tsis kam ntawm carbon thiab graphite tuaj yeem txhim kho, thiab qhov ua haujlwm kub tuaj yeem nce ntxiv.
2. Cov thermal conductivity zoo heev. Graphite hmoov kuj muaj cov thermal conductivity zoo, uas siab dua cov hlau ntawm cov ntaub ntawv nonmetallic, qeb duas ntawm cov ntaub ntawv nonmetallic. Lub thermal conductivity yog ob zaug ntawm carbon steel thiab xya npaug ntawm stainless hlau. Yog li ntawd, nws yog qhov tsim nyog rau cov khoom siv hluav taws xob hloov hluav taws xob.
3. Zoo heev corrosion kuj. Txhua yam carbon thiab graphite muaj kev tiv thaiv zoo heev rau txhua qhov kev sib xyaw ntawm hydrochloric acid, phosphoric acid thiab hydrofluoric acid, suav nrog cov xov xwm fluorine. Daim ntawv thov kub yog 350 ℃ -400 ℃, uas yog, qhov kub ntawm cov pa roj carbon thiab graphite pib oxidize.
4. Qhov saum npoo tsis yooj yim rau cov qauv. Qhov "affinity" ntawm graphite hmoov thiab cov xov xwm feem ntau yog me me, yog li cov av tsis yooj yim rau kev ua raws li qhov chaw. Tshwj xeeb tshaj yog rau cov khoom siv condensation thiab cov khoom siv crystallization.
Cov lus piav qhia saum toj no tuaj yeem ua rau koj nkag siab tob dua ntawm graphite hmoov. Qingdao Furuite Graphite tshwj xeeb hauv kev ua thiab tsim cov graphite hmoov, flake graphite thiab lwm yam khoom. Koj tuaj yeem tuaj xyuas thiab coj peb lub Hoobkas.
