Muffle rauv, tseem hu ua lub thawv hom rauv, yooj yim los tswj, lub cub tawg yog nruab nrog lub chimney tswj. Nws tuaj yeem siv rau hauv hluav taws xob hluav taws xob, ntawv, petrochemical, cement, kev ua liaj ua teb thiab tsiaj txhu, kev tshawb fawb txog kev kho mob, kev qhia thiab lwm yam kev lag luam thiab chaw ua haujlwm. Nyob rau tib lub sijhawm, nws kuj tseem tsim nyog rau kev tshuaj xyuas cov thee, coking khoom thiab cov khoom siv tshuaj lom neeg.
Muffle furnace yog siv dav hauv cov hmoov tshauv, cov teeb meem tsis haum, kev txiav txim siab tag nrho cov sulfur thiab cov hmoov tshauv ntawm cov thee. Nws yog ib qho ntawm cov khoom siv feem ntau siv rau kev tsom xam cov thee zoo.

Qauvntawm Muffle Furnace
Muffle furnace los ntawm daim ntawv thov feem ntau muab faib ua ob qhov loj: rauv lub cev thiab cov maub los.
Lub tshuab ua kom sov lub cev muaj lub plhaub, txheej rwb thaiv tsev, qhov cub chamber thiab cov khoom cua sov.
1, Lub plhaub yog welded los ntawm lub kaum sab xis steel thiab steel phaj, kom yooj yim nkag tau, lub nraub qaum ntawm lub plhaub tau yooj yim tshem tawm lub qhov rooj me me.
2, rwb thaiv tsev txheej los ua lub luag haujlwm hauv kev rwb thaiv tsev thiab rwb thaiv tsev. Kev khiav hauj lwm kub hauv qab 950 degrees nyob rau hauv lub muffle furnace, nrog hluav taws xob cua sov hlau raws li ib tug cua sov caij, nrog lub teeb rwb thaiv tsev cib los yog aluminium silicate paj rwb rwb thaiv tsev; ua hauj lwm kub hauv qab 1300 degrees nyob rau hauv lub high-kub rauv, nrog silicon-carbon pas nrig raws li ib tug cua sov caij, nrog refractory bricks li rwb thaiv tsev ntaub ntawv.
3, Lub cub tawg chamber feem ntau yog duab plaub.
4, Hluav taws xob xaim hluav taws xob kub qhov cub chamber nrog me me nthuav coefficient ntawm siab corundum ua, thiab rau ob chav qauv nrog qhov; silicon-carbon pas nrig high-temperature rauv nrog siab alumina cib ua rau hauv ib lub chamber. Hluav taws xob cua sov xaim los ua cov khoom cua sov, hnav hauv chamber ntawm lub qhov los ntawm lub qhov, los ntawm lub chamber tsis tuaj yeem pom; silicon-carbon rod high-temperature furnace heating element yog silicon-carbon pas nrig, nthuav tawm hauv lub chamber, yog li lub qhov rooj tau nruab nrog kev hloov mus los, thaum lub qhov rooj qhib tau txiav tawm lub zog kom muaj kev nyab xeeb.
Kev khiav hauj lwm cov cai rau kev txiav txim siab ntawm tshauv thiab volatile nyob rau hauv Muffle furnace
【Tshuaj tua hluav taws】
1. Slow Ashing method:
(1) Cov qauv ntsuas tau raug coj tawm ntawm lub tshuab ziab khaub ncaws, (tsis txhob thim cov qauv) mus rau qhov kub thiab txias ntawm lub qhov cub Muffle uas nws qhov kub tsis tshaj 100 degree. Kaw lub qhov cub thiab tawm qhov sib txawv ntawm li 15 hli ntawm lub qhov rooj rau qhov cub, thiab maj mam nce mus rau 500 degree tsis pub tsawg tshaj 30 feeb, thiab tuav ntawm qhov kub no rau 30 min. Txuas ntxiv kom sov txog (815 degree ± 10 degree) thiab hlawv ntawm qhov kub no rau 1h.
(2) Tshem tawm cov hmoov tshauv tawm ntawm lub qhov cub, muab tso rau ntawm lub tshav kub-resistant porcelain phaj lossis asbestos phaj, txias hauv huab cua li 5 feeb. Tom qab ntawd txav nws mus rau hauv lub tais kom qhuav, txias rau hauv chav tsev kub, thiab tom qab ntawd xa mus rau chav sib npaug rau qhov hnyav.
(3) Rau kev kuaj xyuas kub, 20 min txhua lub sijhawm, kom txog rau thaum qhov kev hloov pauv loj tom qab ob qhov kev kub hnyiab tsis ntau tshaj 0.0010g, raws li qhov zoo ntawm qhov kawg kub kub.
2. Txoj kev ashing sai
(1) Tshem tawm cov tais diav (thawj cov hmoov tshauv nrog cov qauv thee) ntawm lub tshuab ziab khaub ncaws, qhib lub qhov rooj Muffle furnace uas yog pre-rhuab mus rau 815 degree. Muab cov hmoov tshauv tso rau ntawm qhov kub ntawm qhov cub qhov cub, thiab maj mam thawb rau hauv lub qhov cub Muffle. Tos 5-10 feeb tom qab cov qauv thee tsis haus luam yeeb, thiab thawb cov hmoov tshauv ntxiv rau hauv qhov kub ntawm qhov cub ua ntu zus ntawm qhov ceev tsis pub tshaj 2 cm ib feeb (yog tias cov qauv thee tawg ntawm hluav taws, qauv yuav muab pov tseg.
(2) Kaw lub qhov cub thiab hlawv ntawm (815 ± 10) degree rau 40 min
(3) Tshem tawm cov hmoov tshauv tawm ntawm lub qhov cub, muab tso rau hauv qhov cua kom txias li 5 feeb, txav mus rau hauv lub tshuab ziab khaub ncaws kom txias rau hauv chav sov, thiab xa mus rau hauv chav sib npaug kom "hnyav".
Rau kev soj ntsuam kev kub hnyiab, 20 min txhua lub sijhawm kom txog rau thaum qhov kev hloov pauv loj tom qab ob qhov kev kub hnyiab tsis ntau tshaj 0.0010g, qhov loj tom qab qhov kawg hlawv yog lub hauv paus rau kev suav. Yog tias qhov kev kuaj xyuas kub tsis ruaj khov, nws yuav tsum tau rov txiav txim siab los ntawm txoj kev ashing qeeb. Lus Cim: Lub coke yog hlawv rau 2 teev.
【Kev tua hluav taws ntawm volatile compounds】
(1) Tshem tawm lub crucible thav duab nrog cov qauv ntawm lub tshuab ziab khaub ncaws thiab muab tso rau ntawm Muffle hearth, uas yog rhuab mus rau 920 degree ua ntej.
(2) Qhib lub qhov rooj rauv thiab muab cov crucible thiab cov qauv ntawm chromium hlau khib rau hauv qhov kub thiab txias, tam sim ntawd kaw lub qhov cub thiab lub sij hawm, cua kub kom raug rau 7 min
(3) Lub crucible thiab txee yog muab tso rau hauv lub cub tawg kub yuav tsum rov qab mus rau (900 ± 10) degree nyob rau hauv 3 feeb, thiab ces nyob twj ywm ntawm (900 ± 10) degree, txwv tsis pub tus qauv yog scrapped.
(4) Tshem tawm lub crucible los ntawm lub cub tawg, txias nws hauv huab cua li 5 feeb, txav mus rau hauv lub tshuab ziab khaub ncaws, txias rau hauv chav tsev kub, thiab xa mus rau hauv chav sib npaug.
(5) Muab lub crucible tso rau hauv lub qhov cub thiab tshem tawm lub crucible, tsis txhob co tawm lub crucible cover, thaum tus qauv muab pov tseg.
(6) Yog tias tsuas muaj ib qho qauv xwb, lub khib nyiab crucible yuav tsum tau ntim nrog khoob crucible kom paub meej qhov kub thiab txias thiab xyuas kom meej cov ntaub ntawv tsis hloov pauv.
Qhov txawv ntawm amufflerauvthiab ib lub qhov cub
Muffle qhov cub thiab qhov cub feem ntau yog siv cov khoom siv cua sov hauv chav kuaj, tab sis lawv lub luag haujlwm thiab hom kev ua haujlwm txawv.
Muffle qhov cub feem ntau yog siv rau kev sim ntsuas kub, feem ntau ncav cuag qhov kub siab tshaj 1000 degree. Muffle furnace feem ntau siv hluav taws xob los yog roj rau cua sov, thiab muaj kev tswj xyuas qhov kub thiab txias. Nws tuaj yeem siv rau hauv fused iav, kub kub tshuaj tiv thaiv, ceramic manufacturing thiab lwm yam kev sim.
Cov qhov cub feem ntau yog siv rau kev ziab kom qhuav thiab kub tsis tu ncua. Nws yog tsuas yog cua sov los ntawm hluav taws xob cua sov, uas tuaj yeem tswj qhov kub ntawm kaum ob degrees Celsius thiab ntau pua degrees Celsius. Qhov cub yog dav siv hauv chemistry, biology, zaub mov, tshuaj thiab lwm yam kev sim, xws li ziab, kev txiav txim siab noo noo, kab lis kev cai aseptic, thiab lwm yam.
LIB Environmental yog ib qho ntawm cov kws tshaj lij thiab cov tuam txhab tsim khoom lag luam kev nyab xeeb thiab ib puag ncig kuaj hauv Suav teb. Nruab nrog lub Hoobkas tshaj lij, peb tuaj yeem muab koj tus nqi sib tw tshaj plaws ntawmLab Muffle Rauv.
Tam sim no peb muaj zoo Lab Muffle Rauv thiab lwm qhov cub rau muag. Tsuav koj muaj kev tsis ntseeg txog kev ntsuas ntsev ntsev corrosion, xav nrhiav kev daws teeb meem, lossis koj xav siv lub tshuab no, thov koj xav tiv tauj peb.
