Bimetallic daim hlau tsis yog ib hom khoom siv tab sis ib pawg dav ntawm daim hlau tsim los ntawm kev sib txuas ob hlau nrog cov khoom sib txawv siv cov txheej txheem tshwj xeeb. Cov hom feem ntau yog hnav- cov phaj sib xyaw thiab cov phaj sib xyaw ua ke; txoj kev xaiv yog nyob ntawm koj daim ntawv thov tshwj xeeb.
Hom twg muaj qhov zoo tshaj plaws hnav tsis kam thiab kav ntev?
Yog tias koj xav tau cov ntaub ntawv rau siab - hnav ib puag ncig- xws li cov mines, cement nroj tsuag, los yog cov chaw nres nkoj -bimetallic hnav- resistant composite steel phaj yog tus qauv xaiv. Cov no yog tsim los ntawm overlay-welding high-chromium alloy hnav- txheej tiv thaiv mus rau lub hauv paus ntawm cov hlau zoo tib yam (xws li Q235), tsim kom muaj kev sib txuas ntawm ob qho tib si. Qhov tawv tawv tuaj yeem ncav cuag HRC 62-66, muab 20-25 npaug ntawm kev hnav tsis kam ntawm tus qauv qis- carbon hlau. Lawv muaj kev cuam tshuam-resistant thiab tuaj yeem welded lossis txiav. Cov kev qhia tshwj xeeb muaj xws li 5+3, 6+4, thiab 8+6 (qhov twg thawj tus lej yog tag nrho cov tuab thiab qhov thib ob yog qhov tuab ntawm hnav- txheej tiv thaiv). Cov nqi sib txawv raws li qhov tshwj xeeb thiab cov chaw tsim khoom-xws li ntawm pua pua yuan ib square meter mus rau ntau txhiab yuan ib tuj- yog li nws yog qhov zoo tshaj plaws los sab laj tus neeg muag khoom kom paub meej.
Hom twg pab txuag cov nqi hlau muaj nuj nqis?
Yog tias koj ua haujlwm hauv kev lag luam tshuaj, kev tsim nkoj, lossis kev tsim cov hlab ntsha siab, cov txheej txheem bimetallic composite daim hlau yog qhov tsim nyog. Ua los ntawm kev sib tsoo tawg lossis yob sib txuas, cov phaj no sib xyaw ua ke ntawm corrosion- tiv taus lossis siab - cov hlau muaj zog (xws li stainless hlau, titanium, lossis tooj liab) nrog cov hlau zoo tib yam. Txoj kev no ua kom muaj kev tiv thaiv corrosion thaum txo tus nqi ntawm cov hlau tseem ceeb uas xav tau, yog li txo cov nqi. Piv txwv xws li titanium-steel thiab stainless-steel composite plates, uas yog siv dav hauv petrochemicals, shipbuilding, thiab cov khoom siv fais fab.
Hom twg khoov tau txais kev hloov pauv kub?
Kuj tseem muaj cov khoom siv hu ua "thermostatic bimetal." Nws muaj ob txheej hlau nrog sib txawv thermal expansion coefficients sib txuas ua ke; Thaum rhuab, qhov sib txawv ntawm deformation ua rau cov khoom khoov tau. Nws yog feem ntau siv rau hauv cov khoom siv me me xws li cov khoom siv ntsuas kub, cov khoom tiv thaiv overload, thiab cov twj paj nruag. Feem ntau xws li los ntawm 0.1 mus rau 2.5 hli nyob rau hauv thickness, qhov no yog ib tug txawv chav kawm ntawm cov khoom los ntawm industrial daim hlau hais ua ntej lawm.
Qhov kev xaiv nyob ntawm koj daim ntawv thov feem ntau: xaiv hnav- cov phaj resistant rau siab - hnav khaub ncaws; xaiv cov qauv sib xyaw phaj yog tias koj xav tau kev tiv thaiv corrosion thiab txuag nqi; thiab xaiv cov khoom siv thermostatic bimetal rau kev tswj qhov kub thiab txias. Nws raug nquahu kom koj qhia meej txog koj qhov kev siv tshwj xeeb ua ntej kev sab laj cov neeg muag khoom txog cov lus qhia tshwj xeeb thiab tus nqi.
