Dub titanium yog cov khoom siv hlau tsis muaj steel uas siv cov txheej txheem tshwj xeeb xws li electroplating lossis dej plating los ua kom cov hlau tsis muaj xim dub. Txoj kev kho no tsis tsuas yog txhim kho cov hniav zoo nkauj ntawm cov hlau tsis huv, tab sis kuj txhim kho nws cov corrosion kuj, hnav tsis kam, thiab UV tsis kam. Cov ntaub ntawv ntawm cov xim dub titanium stainless hlau phaj feem ntau suav nrog ntau hom stainless hlau xws li 201, 304, thiab 316, thiab cov tuab ntawm 0.28mm txog 5mm. Nyob rau hauv cov nqe lus ntawm lub cev khoom, qhov ceev ntawm dub titanium stainless hlau yog hais txog 7.92 g / cm³, elastic modulus yog 200 GPa, lub tensile zog yog 520 MPa, lub elongation yog 40%, thiab hardness yog 207HBW. Hais txog cov tshuaj muaj pes tsawg leeg, nws muaj qee qhov kev faib ua feem ntawm cov ntsiab lus xws li carbon, silicon, manganese, phosphorus, sulfur, chromium, nickel, thiab molybdenum. Cov hom dub titanium stainless hlau muaj xws li dub titanium txhuam, dub titanium frosted, thiab dub titanium daim iav, thiab lwm yam. Cov hom no yuav siv cov txheej txheem kev kho deg sib txawv thaum ua, xws li daim iav polishing, txhuam sandblasting, los yog etching. Ntawm lawv, cov titanium dub daim iav stainless hlau phaj yog tsim los ntawm kev sib tsoo thiab polishing lub zoo tib yam stainless hlau phaj, thiab ces titanium plating nws los tsim ib tug corrosion-resistant dub titanium txheej ntawm nws nto. Cov txheej txheem ntau lawm ntawm titanium stainless hlau feem ntau suav nrog electroplating thiab dej plating. Cov xim ntawm electroplating yog grey, thaum cov xim ntawm cov dej plating yog dub. Yog tias 304 lossis 316 stainless hlau daim hlau siv rau dej plating ntawm titanium dub, xim tuaj yeem hloov kho rau xim dub lossis xiav raws li cov neeg siv khoom xav tau. Cov xim dub titanium stainless hlau phaj yog qhov yooj yim hauv cov txheej txheem ua, xim ruaj khov, thiab teeb meem xim sib txawv tsis tshua muaj tshwm sim. Nws muaj zog kho kom zoo nkauj. Dub, raws li ntau yam xim, tuaj yeem siv rau ntau yam scenes los tsim kom muaj qhov zoo nkauj zoo nkauj thiab zoo nkauj.
Puas muaj titanium dub?
Titanium suboxide
Titanium suboxide yog cov khoom siv ua haujlwm siab thiab ntshiab dub inorganic tshiab lub zog ua haujlwm. Nws cov xim yog dub. Hais txog cov qauv tshuaj, nws yog nruab nrab ntawm titanium dioxide (TiO2) thiab hlau titanium. Nws muaj ntau hom ntawv, suav nrog polycrystalline thiab crystalline cov ntaub ntawv, ntawm cov ntaub ntawv feem ntau yog anatase thiab rutile. Cov qauv ntawm anatase-type titanium dioxide yog tetragonal, thiab cov qauv ntawm rutile-type titanium dioxide yog hexagonal. Titanium dioxide yog ib puag ncig tus phooj ywg thiab tsis muaj tshuaj lom, ua tau raws li cov qauv kev nyab xeeb ntawm cov zaub mov, tsis ua rau cov tawv nqaij puas tsuaj, thiab ua tau raws li cov kev xav tau ntawm kev lag luam qis carbon. Titanium dioxide muaj hluav taws xob zoo conductivity, tshwj xeeb tshaj yog Ti4O7 theem, nws ib leeg siv lead ua conductivity siab li 1500S / cm³. Tsis tas li ntawd, titanium dioxide kuj muaj thermal stability thiab zoo dispersibility thiab tuaj yeem sib npaug ntawm cov dej thiab cov resin. Cov yam ntxwv dub ntawm titanium dioxide ua rau nws siv dav hauv photocatalysts, roj teeb electrode cov ntaub ntawv, LED dub matrix cov ntaub ntawv, thiab lwm yam. Vim nws qhov tshwj xeeb lub cev thiab tshuaj lom neeg, titanium dioxide tuaj yeem siv los ua cathode los hloov graphite hauv lub roj teeb kom txo tau qhov capacitance attenuation los ntawm kev them nqi thiab tawm mus. Nyob rau tib lub sijhawm, nws tseem qhia tau tias kev ua haujlwm zoo hauv kev lag luam tshuaj, electrometallurgy, electroplating, kev tiv thaiv ib puag ncig, thiab kev kho dej.
Dub titanium dioxide
Cov tsoos titanium dioxide yog cov xim dawb siv dav hauv cov txheej txheem, yas, papermaking, thiab lwm yam lag luam. Txawm li cas los xij, titanium dioxide tuaj yeem ua dub los ntawm kev kho tshuaj tshwj xeeb, xws li hydrogenation, tshuaj txo qis, thiab anodization-annealing.
Piv nrog rau cov tsoos dawb titanium dioxide, cov titanium dioxide dub no nthuav tawm lub teeb pom kev zoo thiab kev thauj mus los ntawm hluav taws xob, tau txhim kho qhov muag pom kev, thiab tuaj yeem nqus lub teeb los ntawm ultraviolet mus rau infrared thaj tsam ntawm lub hnub ci spectrum, feem ntau yog vim nws qhov tshwj xeeb core-plhaub. qauv, nyob rau hauv uas lub plhaub sab nrauv yog ib qho tsis muaj oxygen amorphous txheej thiab lub hauv paus tseem ceeb yog thawj crystalline theem. Titanium dioxide nrog cov qauv no nthuav tawm ntau dua kev ua haujlwm hauv photocatalytic kev ua tau zoo, tshwj xeeb tshaj yog nyob rau thaj tsam pom thiab ze-infrared lub teeb, uas yog qhov tseem ceeb rau kev txhim kho kev siv lub hnub ci zog. Qhov no ua rau nws muaj peev xwm siv tau tus nqi hauv thaj chaw ntawm photocatalysis, hnub ci hlwb, hnub ci thermal sau, thiab lwm yam thiab muab kev tshawb fawb tshiab rau kev siv peev xwm ntawm titanium dioxide hauv lub zog teb.
