Yintoni umbhobho wentsimbi engacocekanga?

Iimbono: 0 Umbhali: Umhleli we-Gades Shipasha ixesha: 2022-03-15 Imvelaphi: Indawo

Ibakala le-Sokowila Zininzi izinto zokungenisa elizweni minyaka le.

1. Uhlalutyo olungaphezulu lwensimbi engenasimo

Zombini iindlela ze-AES kwaye indlela ye-SPS ingasetyenziselwa ukuhlalutya umphezulu wensimbi engenasimo ukufumanisa ubuchule bokungabikho komphezulu womhlaba wangaphakathi nowangaphandle kwentsimbi engenasiseko. I-diameter yohlalutyo ekhutshwe yi-AES incinci kakhulu, enokuba ngaphantsi kwe-20nm. Umsebenzi wayo wokuqala kukuchonga izinto. Ixabiso lohlalutyo lwendlela ye-XPS imalunga ne-10μm, esetyenziselwa ukumisela imeko yekhemikhali yezinto ezikufutshane nomphezulu.

Ukuskena umphezulu ovuthiweyo we-316 intsimbi enesibetho esivele kwimozulu kunye nabacimisi be-XPS ibonisa ukuba eyona nto iphambili kuhlalutyo lwe-15NM, kwaye ibonelela ngolwazi malunga nokubekwa kunye nobungqingqwa bomaleko. Ukuchasana nokunganyangeki.

Ngokwenkcazo, intsimbi engenasimo i-austenitic iqulethe i-chromium ephezulu kunye ne-nickel, kwaye ezinye ziqulathe i-molybdenum, i-titanium, njl njl. Ukuchasana nokunganyangeki sisiphumo sepropathi yokukhusela ye-chromium etyebileyo. Umaleko wevenkile uhlala u-3-5nm ubukhulu, okanye olingana neeathom ezili-15. Umaleko we-plastivad wenziwa ngexesha lenkqubo yokuphelisa i-oxidation apho i-chromium kunye nentsimbi i-oxidod. Ukuba umaleko wepasile wonakalisiwe, kuya kwenziwa umaleko omtsha wokudluliselwa ngokukhawuleza kwaye i-electrochemional i-Electrochenion iya kwenzeka ngokukhawuleza, kwaye iindawo ezinzulu zensimbi ziya kuvela. I-colovion kunye ne-inrasion yosulelo. Ukunganyangeki kohlobo lokucoca unxulumene nemixholo yezinto zekhemikhali ezikwintsimbi engenasimo, njengeChromium ephezulu, i-NECKEL yaseMolybdenum, njl. Njl. kwaye uyisebenzise ngomphezulu wangaphakathi wombhobho wentsimbi engenasimo. I-fluid wine ihambelana.

I-2. Ukuphakanyiswa komphezulu wombhobho wentsimbi engenasitayile

. Ukuba umaleko we-plareper kuphela kwintsimbi, umaleko oshicilelweyo uya kuqhubeka nokuyalela. Kwiimeko ezininzi, umaleko wedleleni wonakaliswa kuphela kwindawo yendawo yomphezulu wensimbi. Iziphumo ze-corrosion yenze imingxunya encinci okanye imingxunya. Imingxunya encinci esasazwe ngokungacwangciswanga kumphezulu wezinto ezibonakalayo zibizwa ngokuba yindawo yokuthambisa. Ireyithi yokucoca i-pirsion inyuka ngokukhulisa ubushushu obandayo kwaye yonyuka ngokukhulisa uxinzelelo. Isisombululo kukusebenzisa i-ultra-cal-carbon yentsimbi (njenge-316l okanye i-304L)

. Xa iqondo lobushushu lokufudumeza kunye nesantya sokufudumeza ngexesha lokuvelisa kunye ne-welding sikwindawo yokushishina ngentsimbi engenasithambisi (emalunga ne-425-815 ° C), i-probon ene-proorium yeza kuqala i-chromium carbide kwaye iphulukane neChromium. Ngenxa yoko, umxholo we-chromium womda wengqolowa uyaqhubeka nokuncipha ngokuqhubeka kwe-chromium carbide, ebizwa ngokuba yindawo ebizwa ngokuba yi-chiromium epheleleyo kwaye inciphisa ukunganyangeki kwe-coromion yomaleko. Xa kunxibelelana nemithombo yeendaba zobutyebi ezinjenge-ci- tic ephakathi, iya kubangela i-corrosion encinci. Nangona i-corrosion iphezu kobuso obuziinkozo, ingene ngokukhawuleza ngaphakathi ngaphakathi kwi-Internation yokucoca i-insosion. Ngakumbi imibhobho yentsimbi engenasitayile icacile kakhulu kwinxalenye yonyango lwe-welding.

. Imo yokusingqongileyo yokuqhekeka koxinzelelo idla ngokuntsonkothileyo. Ayisiyiyo kuphela uxinzelelo lobungqingisi, kodwa ukudityaniswa kolu xinzelelo kunye noxinzelelo olushiyekileyo kwisinyithi ngenxa ye-nyibilithi, i-welding, okanye unyango lobushushu.

3. Inkqubo yemveliso ye-bonial ye-bonigy yentsimbi engenasitayile

I-Willing engagungqiyo

Kucetyiswa ukuba usebenzise i-Steid yensimbi yentsimbi yentsimbi I-Hingao Tech (Matshini weSeko) . Kuba i-stript yentsimbi isetyenziselwa ngokuthe ngqo kwi-welding emva kokwenziwa, ukunyamezelana kunye nokuthambisa kombhobho kunokulawulwa kakuhle, kwaye inkqubo yomzobo obandayo inokushiywa.

Kukho izixhobo ezininzi eziphambili kwimveliso:

(1) Isixhobo seNqanaba elingaphakathi Ngexesha lokuPhila kwangaphakathi kunye nePoling yangaphandle, inokunciphisa inani kunye nobunzulu be-pile yokuphola kunye nokunciphisa ilahleko.

(2) Irhasi yokukhusela irhasi eqaqambileyo)

Umbutho oqaqambileyo weXesha eliqaqambileyo: Isakhiwo esikhulu licandelo elijikelezayo Ukufudumeza isithando somlilo , nto leyo eyamkela indlela yokufudumeza yokufumana iikhola zokufudumeza, ukuze lonke icandelo lendlela linokufudunyezwa kuzo zonke iindlela. Irhasi yokukhusela ayisebenzi nje njengomqobo emoyeni, kodwa ikwasebenza njengokujikeleza umoya okupholileyo. Ubume be-compact, ukusebenza ngokukhuselekileyo, ulawulo oluthembekileyo kunye nolondolozo olululo. Umahluko weqondo lobushushu kwisiko lilawulwa ngaphakathi kwi ± 1-2 ℃.

Abavelisi banokukhetha ukusebenzisa izixhobo ze-Amonia Dearication Izixhobo zokwenza irhasi yokukhusela okanye ngokuthe ngqo irhasi ye-calty ngokweemeko zabo.
