Kev kho blackening ntawm U-shaped cua sov raj feem ntau muaj ob peb kauj ruam yooj yim:

Kev kho blackening ntawm U-shaped cua sov raj feem ntau muaj ob peb kauj ruam yooj yim:

1. Dab tsi yuav tsum tau ua yog tshem tawm cov organic teeb meem ntawm qhov chaw, uas yog hu ua degreasing kev kho mob. Txhua tus neeg yuav tsum tau so kom paub tseeb tias kev kho degreasing yooj yim ua tiav ntawm no. Defatting kev kho mob tsuas yog yuav tsum muaj cov tshuaj degreasing. Thiab cov tshuaj degreasing kuj yooj yim muaj nyob hauv khw. Qhov yuav tsum tau ua rau kev kho degreasing yog kom tswj tau qhov siab alkalinity ntawm cov kua, nrog rau cov pH ruaj khov ntawm ib ncig ntawm 13. Lub sijhawm yuav tsum tau ua yog kwv yees li 30 feeb. Tom qab qhov kev kho no, qhov saum npoo yuav tsum tau ntxuav kom tshem tawm cov impurities tsim los ntawm cov tshuaj tiv thaiv. Kev ntxuav yuav tsum tau ua nrog dej huv kom ntseeg tau tias muaj kev huv huv ntawm qhov chaw ntawm lub raj cua sov.

2. Qhov yuav tsum tau ua ua ntej rau kev kho blackening yog ua kom lub ntsej muag ntawm lub raj cua sov kom huv si thiab huv si. Yog hais tias muaj impurities rau ntawm nws nto, nws yuav tsis conducive rau blackening kev kho mob.

3. Tom qab ua tiav peb kauj ruam saum toj no, nws yog ib qho tsim nyog los xyuas kom meej tias Ph nyob nruab nrab ntawm 2-4. Lub sijhawm 10 feeb yog txaus. Tom qab ua tiav, pib nrog kev tu.

5, Qhuav lub cua sov raj. Kev ziab yog ua kom tshem tawm cov dej adhering rau saum npoo ntawm lub raj cua sov. Thaum kawg, nws yog lub sijhawm los thov roj.

4. Tom qab alkaline ntxuav, nws yuav tsum tau pickled. Vim nws qhov chaw tsis yog tsuas yog muaj alkaline organic teeb meem, tab sis kuj acidic organic teeb meem. Yog li acidic tu kuj tseem tsim nyog. Tus nqi pH ntawm 3 yog xav tau rau acidity, thiab lub sijhawm ua haujlwm yuav tsum tsis pub tshaj 10 feeb.

Ultra-siab kub tungsten rhenium thermocouple muaj ib txheej txheej tiv thaiv raj, thiab cov khoom siv tiv thaiv siv yog tungsten raj lossis tantalum raj. Tam sim no, muaj ob peb lub tuam txhab tsim hluav taws xob ntawm ultra-siab kub tungsten rhenium thermocouples, thiab tseem muaj ob peb lub tuam txhab tshawb nrhiav ultra-siab kub tiv thaiv raj thiab cov ntaub ntawv rwb thaiv tsev. Yog vim li cas yog vim li cas kev lag luam sib koom ntawm ultra-siab kub tungsten rhenium thermocouples yuav tsum tau nyob rau hauv lub tshav pob ntawm ultra-siab kub ntsuas yog me me, qhov nyiaj khwv tau los yog me me, thiab kev tshawb fawb nyuaj thiab peev nqi yog siab dhau, uas ua rau muaj ntau yam khoom siv txawv teb chaws. kom muaj kev nyuaj rau kev tswj xyuas thiab yuav cov khoom no. Kev yuav cov khoom no los ntawm txawv teb chaws muaj lub voj voog ntev thiab tus nqi siab. Cov khoom muaj qhov muaj kev nyab xeeb txaus rau nws qhov kev siv kub. Vim lub hardness thiab brittleness ntawm tungsten thiab tantalum tiv thaiv tubing nyob rau hauv chav tsev kub nyob rau hauv Tuam Tshoj, cov neeg siv yuav tsum tau xav txog tag nrho cov muaj feem xyuam rau lub uncertainties thaum lub sij hawm installation los tiv thaiv kev puas tsuaj rau cov hlab tiv thaiv.

Qhov ntsuas kub ntawm qhov ntsuas kub ntawm ultra-siab kub tungsten rhenium thermocouple yog 0-2300 degree, thiab qhov kub siab tshaj ntawm cov khoom no tuaj yeem ncav cuag 2600 degree, ua rau nws qhov kub siab tshaj ntsuas tungsten rhenium thermocouple hauv tsev thiab txawv teb chaws. Txawm li cas los xij, lub peev xwm thermoelectric ntawm tungsten rhenium thermocouple yog tawg tom qab tshaj 2300 degree, uas yuav cuam tshuam qhov tseeb ntawm qhov ntsuas kub. Ultra-siab kub tungsten rhenium thermocouples ua los ntawm peb lub tuam txhab siv domestically tsim tungsten los yog tantalum tiv thaiv tubing, thiab siv nws tus kheej tsim cov ntaub ntawv rwb thaiv tsev uas muaj peev xwm tiv taus 2600 degree ultra-siab kub. Tom qab siv sij hawm ntev hauv kev lag luam hauv tsev ultra-siab kub, lawv tau txais kev lees paub zoo hauv kev lag luam no.
