Muindasitiri yekugadzira makemikari, kusarudzwa kwezvinhu kunopfuura nyaya yekushanda-inyaya yekuchengeteka, kusimba, uye mutengo-kubudirira. Midziyo inoshandiswa muchikamu ichi inofanira kumiramakemikari ane hasha, tembiricha yakakwira, kumanikidzwa kukuru,uyenzvimbo dzinoorazuva nezuva. Apa ndiposimbi isina ngurainoratidza kuva sarudzo yechienzi.
Asi haasi ese masimbi asina tsvina anosikwa akaenzana. Kusarudza giredhi rakakodzera kwakakosha kuti uwane hupenyu hurefu hwebasa, kudzivirira kutadza kwemidziyo, uye kuve nechokwadi chekushanda zvakanaka. Muchinyorwa chino, tinoongorora zvakakosha zvekusarudza simbi isina simbi mukugadzirisa makemikari, iwo akajairika mamakisi, uye iwo chaiwo mabhenefiti. Wakaunzwa kwaurisasaalloy, shamwari yako yaunovimba nayo mumidziyo yesimbi isina tsvina yekunaka kwemaindasitiri.
Nei Stainless Simbi Yakakosha muChemical Processing
Stainless simbi inopa yakasarudzika musanganiswa wekusaita ngura, simba, kudzivirira kupisa, uye kuchena. Kuumbwa kwayo kwechromium-rich inoumba passive oxide layer inodzivirira pamusoro kubva pakurwiswa kwemakemikari-kunyangwe paine maasidhi akasimba, alkali, uye zvinonyungudutsa.
Mabhenefiti akakosha enzvimbo dzemakemikari anosanganisira:
-
Yakanakisa kupikisa kugomba uye crevice corrosion
-
Strong mechanical properties pane zvose yakakwirira uye yakaderera tembiricha
-
Kureruka kwekugadzira uye welding
-
Kuchengetedza kwakaderera uye hupenyu hurefu hwebasa
-
Kuenderana nehutsanana uye yakachena-munzvimbo (CIP) masisitimu
At sasaalloy, tinopa makemikari-giredhi-giredhi zvigadzirwa zvesimbi zvisina simbi zvinosangana nemazinga epasi rose uye zvinodiwa nevatengi.
Zvinhu Zvokufunga nezvazvo Pakusarudza Stainless Simbi
Pakusarudza simbi isina tsvina yemakemikari ekushandisa, mainjiniya anofanirwa kuongorora:
-
Kemikari inoumbwa ye process media
-
Concentration, tembiricha, uye pressure
-
Mhando yekuora (semuenzaniso, general, pitting, stress cracking)
-
Welding nekugadzira zvinodiwa
-
Kutevedzwa kwemitemo uye kwehutsanana
-
Mutengo uye kuwanikwa
Kusawirirana pakati pezvakatipoteredza nezvinhu zvinogona kukonzerakukundikana nguva isati yakwana, kuvharwa kunodhura, uye njodzi dzinogona kuitika.
Yakajairwa Stainless Simbi Magiredhi eChemical Processing
1. 304 Stainless Simbi
-
Composition: 18% chromium, 8% nickel
-
Zvakanakira: Good corrosion resistance, ine mari
-
Kuganhurirwa: Haina kunaka kune chloride-rich nharaunda
-
Applications: Matangi ekuchengetedza, pombi, zvitsigiro zvechimiro
304 inoshandiswa zvakanyanya kune zvakajairwa-chinangwa chemakemikari michina, kunyanya kupimild acidskana nzvimbo dzisina-chloride dziripo.
2. 316 / 316L Stainless Simbi
-
Composition: 16% chromium, 10% nickel, 2% molybdenum
-
Zvakanakira: Yakavandudzwa kuramba kune chlorides uye acidic nharaunda
-
Applications: Reactors, heat exchangers, evaporators, mavharuvhu
316L ineyakaderera carbon content, zvichiita kuti zvive naniwelded applicationsuko kuora pamajoini kunogona kuva njodzi.
3. 317L Stainless Simbi
-
Composition: Yakakwira molybdenum kupfuura 316L
-
Zvakanakira: Kuwedzera kurambachloride pitting uye crevice corrosion
-
Applications: Pulp uye bepa bleaching, makemikari reactors, scrubbers
Kana 316L ikapfupika munzvimbo dzinotyisa zvakanyanya, 317L inopa nhanho yehupfumi mukudzivirira.
4. 904L Stainless Simbi
-
Composition: Yakakwira nickel uye molybdenum zvirimo
-
Zvakanakira: Yakanakisa mukatiyakasimba asidhi nharaundakusanganisira sulfuric, phosphoric, uye acetic acids
-
Applications: Vanopisa kupisa, pickling michina, kugadzirwa kweasidhi
904L inopesana nezvose zvinoderedza uye oxidizing agents uye inonyanya kushanda pakurwisanahutsinye mediapakupisa kukuru.
5. Duplex Stainless Steels (semuenzaniso, 2205, 2507)
-
Composition: Yakaenzana austenitic-ferritic chimiro
-
Zvakanakira: Simba rakakwirira, kupikisa kwakanaka kunestress corrosion cracking
-
Applications: Zvikepe zvekumanikidza, zvinopisa zvinopisa, kushandiswa kwemahombekombe
Duplex simbi isina tsvina inosanganisa akanakisa zvivakwa zve austenitic uye ferritic simbi, zvichiita kuti ive yakakodzera kune yakakwira-kushushikana, chloride-rich application.
6. Alloy 20 (UNS N08020)
-
Zvakanakira: Yakagadzirirwa zvakanangasulfuric acid resistance
-
Applications: Asidhi ekuchengetedza matangi, pickling midziyo, makemikari ekutakura
Alloy 20 inopa yakanakisa dziviriro mukatiacidic uye chloride-yakatakura maitiro, inowanzopfuura 316 uye 904L munzvimbo dzesarufa.
Zvishandiso muKemikari Indasitiri
Simbi isina tsvina inoshandiswa mune ingangoita yese nhanho yekugadzira makemikari, kusanganisira:
-
Matangi ekuchengetedza uye midziyo yekumanikidza
-
Kusanganisa uye kuita makamuri
-
Heat exchangers uye condensers
-
Pombi masisitimu uye mavharuvhu
-
Distillation columns uye scrubbers
Kutenda kune hutsanana uye husina-reactive hunhu, simbi isina tsvina zvakare yakanakiramishongauyekugadzirwa kwemakemikari ezvokudya.
Zvakanakira Kusarudza Giredhi Rakanaka
Kusarudza iyo chaiyo Stainless simbi giredhi inovimbisa:
-
Yakaderedzwa nguva yekudzikira nekuda kwekuora kana kutadza
-
Mari yekuchengetedza yakaderera
-
Hurefu hwehupenyu hwemidziyo
-
Kuvandudzwa kwekuchengetedza uye kutevedzera
-
Zvirinani kudzoka pakudyara
At sasaalloy, timu yedu yehunyanzvi inoshanda nevatengi kuti vaone iyo inodhura-inoshanda alloy mhinduro zvichienderana nemamiriro chaiwo ekushanda-kwete chete dhetabheti kukosha.
Mhedziso
Muindasitiri yekugadzira makemikari, kusarudzwa kwezvinhu isarudzo yehungwaru inobata zvakanangakuita, kuchengeteka, uye pundutso. Iine yakasarudzika corrosion kuramba, kugadzikana kwemafuta, uye michina zvivakwa,simbi isina tsvina inoramba iri ibwe rekonanokuda kwemamiriro emakemikari anoda.
Kunyangwe iwe uri kutarisana neacids, chlorides, kupisa kwakanyanya, kana kudzvanywa,sasaalloyinopa huwandu hwakazara hwesimbi isina simbi mamakisi akagadzirwa kuti aite zvakakwana. Kubva pa304 uye 316L kusvika 904L uye duplex alloys,sasaalloyyakazvipira kuendesa zvinhu zvinoita pazvinonyanya kukosha-mukati mekuita kwako.
