Zirconium Foil Piav Qhia: Cov Khoom, ASTM B551 Qib thiab Qhov Loj

Dab tsi yog Zirconium Foil

Zirconium ntawv ci yog lub thinnest dov daim ntawv ntawm kev lag luam ntshiab zirconium, muab los ua ib daim ntawv txuas ntxiv lossis raws li cov hlua khi thiab ribbon. Nws yog tsim los ntawm txias dov zirconium sawb mus rau thicknesses ntsuas nyob rau hauv pua pua ntawm ib millimeters, nrog intermediate annealing kom cov hlau ua hauj lwm. Qhov twg zirconium sawb thiab phaj siv rau cov txheej txheem liners thiab cov ciam ciam siab, cov ntawv ci yog siv qhov twg cov hlau yuav tsum ua raws li txoj kev sib txawv, ua raws li nyias nyias, lossis sib txuas rau lwm qhov chaw. Qhov sib txawv ntawm cov ntawv ci thiab sawb yog vim li no ib qho ntawm kev ntsuas thiab kev tuav, tsis yog metallurgy: ob qho tib si los ntawm tib daim txhuam cev - muab cov hlau thiab sib faib tib yam kev coj tus cwj pwm.

Lub cev thiab Thermal Properties

Zirconium sib xyaw ua ke qhov sib piv qis thermal neutron absorption cross-section nrog muaj zog tiv thaiv rau ntau hom acids thiab alkalis, thiab ob lub zog ua ke piav qhia feem ntau ntawm nws cov kev xav tau.

Khoom	Tus nqi
Qhov ntom	6.51 g / cm³
Melting point	1855 degree
Boiling point	4 409de
Hom purity ntawm kev lag luam ntawv ci	99.4%
Standard foil thickness ntau yam	0.03-0.3 hli
Txheem foil dav	mus txog 580 mm

Qhov ceev yog hais nyob rau hauv grams ib cubic centimeter, uas yog qhov tseeb chav tsev rau cov cuab yeej ntawm cov hlau nws tus kheej. Ib daim duab qhia ib square meter yog qhov hnyav rau ib cheeb tsam thiab nyob ntawm qhov ntsuas tau dov, yog li nws tsis tuaj yeem piav qhia txog cov khoom siv.

Qib thiab Standards

Zirconium ntawv ci feem ntau raug txiav txim tawm tsam ib ntawm ob lub cev ntawm kev qhia tshwj xeeb. Txoj kev Asmeskas yog ASTM B551 / B551M, tus qauv qhia tshwj xeeb rau zirconium thiab zirconium alloy sawb, ntawv thiab phaj, uas tseem npog cov tin -cov kabmob thiab niobium-cov kabmob alloy qib. Suav txoj kev yog GB / T 21183, lub teb chaws tus qauv rau zirconium thiab zirconium alloy daim hlau, nplooj ntawv, strips thiab foils. Qhov twg ib qhov project hu rau GB / T 21183, tsab ntawv tam sim no yuav tsum raug suav hais tias; xyoo 2007 dhau los no tau hloov pauv thiab yuav tsum tsis txhob muab tso rau hauv kev yuav khoom tshwj xeeb.

Khoom npe	Khoom siv	Purity	Txuj
Zirconium sawb	Zr702, Zr1	99.4%	ASTM B551, GB / T 21183
Zirconium ntawv ci	Zr702, Zr1	99.4%	ASTM B551, GB / T 21183

Zr702 yog cov khoom lag luam ntshiab, qis - qib pa oxygen uas tswj cov tshuaj lom neeg thiab kev pabcuam corrosion. Zr1 yog cov tin - cov kabmob alloy tsim siv qhov twg xav tau lub zog siab dua me ntsis yam tsis tau poob corrosion. Ob qib yog muab los ntawm tib lub rooj sib txawv thiab txawv ntawm chemistry thiab mechanical zog es tsis yog los ntawm cov tsos.

Muaj Qhov Loj

Cov ntawv ci yog dov nyob rau hauv ib ntu ntawm cov tuab tuab, thiab qhov dav thiab ntev uas tuaj yeem muab tau ua siab dav dua li qhov ntsuas tau nce, vim tias qhov hnyav dua tuaj yeem ua rau dov thiab coiling loads zoo dua.

(0.01–0.02) × (30–100) × (Ntau tshaj los yog sib npaug rau 500) mm

(0.03–0.09) × (50–300) × (Ntau dua los yog sib npaug rau 500) mm

(0.10–0.30) × (50–300) × (Ntau tshaj los yog sib npaug rau 500) mm

(0.40–0.90) × (50–500) × (Ntau tshaj los yog sib npaug rau 1000) mm

(1.0–2.0) × (50–500) × (Ntau tshaj los yog sib npaug rau 2000) mm

Thawj peb pawg poob rau hauv cov ntawv ci txhais tau siv ntawm no, nrog rau 0.03-0.09 hli band yog lub tshuab ua haujlwm rau cov nroj tsuag tshuaj thiab txheej txheej. Ob qhov hnyav dua piav qhia txog sawb thiab lub teeb phaj, teev ua ke nrog cov ntawv ci vim tias lawv tawm ntawm tib txoj kab dov thiab feem ntau raug txiav txim ua ib pob ntawm ib qhov project fabrication.

Daim ntawv thov

Qhov loj tshaj plaws ib leeg siv zirconium ntawv ci thiab nyias sawb yog nyob rau hauv cov cuab yeej uas tswj nruj chemistry. Zirconium resists hydrochloric acid, sulfuric acid thiab feem ntau cov organic acids zoo dua li cov hlau tsis muaj steel, thiab nws tsis tawm tsam los ntawm cov alkalis uas pit lwm cov hlau reactive, uas yog vim li cas nws tshwm li liners, tais, tshav kub exchanger internals thiab nyias daim nyias nyias nyob rau hauv tshuaj. Hauv kev lag luam nuclear, tib cov hlau ua haujlwm ua cov roj cladding thiab cov khoom siv hauv cov reactors thiab hauv atomic zog cov kev pab cuam, qhov twg nws tsawg neutron absorption yog txiav txim. Aerospace siv los ua kev sib xyaw ua ke ntawm qhov hnyav thiab siab melting point rau nyias cov khoom raug tshav kub thiab corrosive kua.

Kev tuav thiab tshuaj xyuas

Zirconium ntawv ci yog mos nyob rau hauv cov mob annealed thiab cov cim tau yooj yim, yog li nws feem ntau raug xa tawm ntawm cov ntawv sib cuam tshuam hauv cov ntaub ntawv nruj nrog daim ntawv pov thawj zeb thiab cov ntawv ntim ib sab. Kev tshuaj xyuas tuaj yuav tsum paub meej tias tus naj npawb cua sov tiv thaiv daim ntawv pov thawj, txheeb xyuas qhov tuab ntawm ob peb lub ntsiab lus hla lub kauj lossis daim ntawv, xyuas cov kab nrib pleb thiab dov - nyob rau hauv kev sib kis, thiab paub meej tias tsis muaj hlau paug tau qhia los ntawm kev sib cuag nrog carbon steel thaum tuav. Cia kom deb ntawm noo noo thiab los ntawm kev sib cuag ncaj qha nrog cov hlau sib txawv khaws cia ob qho tib si saum npoo tiav thiab kev ua haujlwm corrosion ntawm cov khoom tiav.
