Sintered SS316L Powder Solid Lim Rau Gas Getters

TOPTITECH's Sintered SS316L Powder Solid Lim For Gas Getters siv roj-atomized 316L stainless hlau kheej kheej hmoov ua raws li ASTM F138 cov qauv nrog cov ntsiab lus oxygen nruj me ntsis hauv qab 300ppm. Cov txheej txheem tsim khoom siv txias isostatic nias ua raws li lub tshuab nqus tsev sintering ntawm qhov kub siab tshaj 1200 degree, tsim cov qauv monolithic ntxeem tau nrog cov pore morphology thiab siab void ntim. Tsis zoo li welded mesh kev tsim kho, cov khoom lim dej no tshem tawm cov kev pheej hmoo ntawm kev tsiv teb tsaws chaw los ntawm kev sib txuas ntawm cov khoom siv hlau ntawm cov ntsiab lus sib cuag, ua kom tsis muaj qhov cuam tshuam thaum lub sij hawm thermal cycling lossis mechanical vibration. Kev sib txuas ntawm qhov pore network tsim cov cheeb tsam sab hauv sab hauv ntau tshaj 500 cm² / g, optimizing chemisorption kinetics rau cov roj reactive hom thaum tuav cov qauv kev ncaj ncees nyob rau hauv qhov sib txawv siab txog li 250 psid.

TOPTITECH's Sintered SS316L Powder Solid Filter For Gas Getters functions as a non-evaporable getter (NEG) support or direct sorptive element in ultra-high vacuum (UHV) ib puag ncig, nquag nqus hydrogen ntawm chav tsev kub thiab tau txais cov pa oxygen, nitrogen thiab dej 5℃ntawm cov pa roj carbon monoxide ua kom muaj zog. 760 degree. Qhov ntxeem tau 316L matrix muab superior thermal stability mus txog 677℃nrog tsawg outgassing, tswj lub tshuab nqus tsev hauv qab 10⁻¹⁰ mbar hauv semiconductor manufacturing, particle accelerator beamlines, thiab hermetically kaw cov khoom siv hluav taws xob. Cov ntawv thov suav nrog MEMS lub tshuab nqus tsev ntim, me me mus ncig-wave tubes xav tau kev tiv thaiv cathode los ntawm kev lom, thiab laser diode TO- tuaj yeem sib dhos qhov chaw noo noo thiab corrosive gas adsorption tiv thaiv facet oxidation. Cov qauv tsim rov qab txhawb nqa rov ua dua tshiab - tawm mus uas tsis muaj kev ua haujlwm degradation, muab cov pa roj impurity tshem tawm hauv kev ntsuas ntsuas thiab kev ua haujlwm hauv aerospace.

Tswj Porosity thiab Pore Loj Distribution

Precise sieving thiab blending ntawm 316L kheej kheej hmoov ua ntej sintering enables ib tug uniform pore qauv nrog nqaim tis. Qhov no ua kom muaj kev sib txawv ntawm cov pa sib txawv thiab cov cwj pwm sorption tuaj yeem pom thoob plaws tag nrho cov lim dej, tshem tawm cov channeling lossis cov chaw tuag uas muaj nyob rau hauv cov ntaub pua tsev.

 

Zoo heev Corrosion Resistance rau Aggressive Gas ib puag ncig

Lub 316L austenitic qauv nrog molybdenum ntxiv muab kev tiv thaiv rau halides thiab sulfur- hom kabmob. Qhov no tiv thaiv qhov chaw passivation uas yuav txwv tsis pub cov chaw nquag nquag thaum lim cov txheej txheem nruj heev lossis tiv thaiv cov khoom hauv qab.

 

High Mechanical Strength nrog nyias phab ntsa siv

Cold isostatic pressing achieves green density uniformity, allowing sintered wall thicknesses as low as 1.5mm while withstanding differential pressures exceeding 200 psid. Qhov no txo ​​qis kev txwv tsis pub khiav thaum tuav cov txheej txheem kev ntseeg siab thaum rov qab -pulsing lossis hloov siab ceev.

 

Reusable Los ntawm Ultrasonic Tu thiab Re- ci - tawm

Cov sintered hlau matrix tiv taus cov txheej txheem tu nruj nrog rau ultrasound hauv cov kuab tshuaj organic ua raws li siab - nqus tsev vacuum - tawm. Qhov no restores thawj cov yam ntxwv ntws thiab tau txais kev ua ub no yam tsis muaj qhov hloov pauv los yog cov khoom degradation.

 

Bimodal Pore Structure Muaj peev xwm

Engineered hmoov gradations tuaj yeem tsim dual -porosity architectures qhov twg cov dej ntws loj dua txhawb nqa cov pa xa mus sai thaum micro- cov cheeb tsam ntxeem tau ua kom thaj chaw loj tshaj plaws rau chemisorption. Qhov no optimizes qhov sib npaug ntawm kev siv ceev thiab tag nrho cov peev xwm tau txais hauv ib feem.

 

Tsis muaj Particle Shedding lossis Media Migration

Lub metallurgical bonding ntawm kheej kheej hais kom meej meej tuav ntawm lub lim matrix nws tus kheej. Qhov no tshem tawm cov cim tshwj xeeb uas tuaj yeem cuam tshuam cov txheej txheem qis qis xws li cov kab hluav taws xob hluav taws xob lossis cov khoom ua haujlwm wafer.
