Daim ntawv thov ntawm silicon carbide ceramics hauv thaj chaw photovoltaic

① Nws yog cov khoom siv tseem ceeb hauv cov txheej txheem tsim khoom ntawm cov hlwb photovoltaic
Ntawm cov khoom siv silicon carbide structural ceramics, kev lag luam photovoltaic ntawm silicon carbide nkoj txhawb nqa tau tsim kho ntawm qib siab ntawm kev vam meej, dhau los ua qhov kev xaiv zoo rau cov ntaub ntawv tseem ceeb hauv cov txheej txheem tsim khoom ntawm photovoltaic cell, thiab nws qhov kev thov ua lag luam tau nyiam kev saib xyuas ntxiv los ntawm kev lag luam.

Tam sim no, cov khoom txhawb nqa nkoj, cov thawv nkoj, cov khoom siv yeeb nkab, thiab lwm yam ua los ntawm quartz feem ntau siv, tab sis lawv raug txwv los ntawm cov khoom siv xuab zeb quartz hauv tebchaws thiab thoob ntiaj teb, thiab lub peev xwm tsim khoom me me. Muaj kev muab khoom thiab kev thov rau xuab zeb quartz huv si, thiab tus nqi tau khiav ntawm qib siab ntev heev, thiab lub neej ua haujlwm luv luv. Piv nrog cov ntaub ntawv quartz, cov khoom txhawb nqa nkoj, cov thawv nkoj, cov khoom siv yeeb nkab thiab lwm yam khoom ua los ntawm cov ntaub ntawv silicon carbide muaj kev ruaj khov thermal zoo, tsis muaj kev hloov pauv ntawm qhov kub siab, thiab tsis muaj cov pa phem precipitated. Raws li cov khoom siv zoo heev rau cov khoom quartz, lub neej ua haujlwm tuaj yeem ncav cuag ntau dua 1 xyoos, uas tuaj yeem txo qhov siv nqi thiab poob ntawm lub peev xwm tsim khoom los ntawm kev saib xyuas thiab kho. Qhov zoo ntawm tus nqi yog qhov pom tseeb, thiab nws daim ntawv thov kev cia siab ua tus neeg nqa khoom hauv thaj chaw photovoltaic yog dav.

② Siv tau ua cov khoom siv nqus cua sov rau cov tshuab hluav taws xob hnub ci
Cov tshuab hluav taws xob thermal hnub ci ntauwd tau txais kev qhuas heev hauv kev tsim hluav taws xob hnub ci vim lawv qhov sib piv siab (200 ~ 1000kW / ㎡), kub siab thermal voj voog, poob cua sov tsawg, lub kaw lus yooj yim thiab ua haujlwm tau zoo. Raws li lub hauv paus tseem ceeb ntawm kev tsim hluav taws xob thermal hnub ci ntauwd, lub absorber yuav tsum tiv taus lub zog hluav taws xob muaj zog 200-300 npaug ntau dua li lub teeb ntuj, thiab qhov kub ua haujlwm tuaj yeem siab txog ntau dua ib txhiab degrees Celsius, yog li nws qhov kev ua tau zoo tseem ceeb heev rau kev ua haujlwm ruaj khov thiab kev ua haujlwm zoo ntawm lub tshuab hluav taws xob thermal. Qhov kub ua haujlwm ntawm cov khoom siv hlau ib txwm muaj tsawg, ua rau cov ceramic absorbers yog qhov chaw tshawb fawb tshiab. Alumina ceramics, cordierite ceramics, thiab silicon carbide ceramics feem ntau siv ua cov ntaub ntawv absorber.

Lub zog hluav taws xob hnub ci thermal absorber tower

Ntawm lawv, silicon carbide ceramics muaj cov yam ntxwv zoo heev xws li lub zog siab, thaj chaw loj, tiv taus corrosion, tiv taus oxidation, rwb thaiv tsev zoo, tiv taus thermal shock thiab kub siab. Piv nrog alumina thiab cordierite ceramic absorber cov ntaub ntawv, nws muaj kev ua haujlwm kub zoo dua. Kev siv lub tshuab nqus cua sov ua los ntawm sintered silicon carbide tso cai rau lub tshuab nqus cua sov kom ua tiav qhov kub ntawm huab cua tawm mus txog 1200 ° C yam tsis muaj kev puas tsuaj rau cov khoom.
