Qhov ceev ntawm titanium hlau yog 4.51g / cm3, uas yog siab dua aluminium tab sis qis dua hlau, tooj liab, thiab npib tsib xee, tab sis nws lub zog tshwj xeeb yog siab dua li cov ntaub ntawv hlau. Lub zog corrosion kuj ntawm titanium alloy li qub yog vim qhov tseeb tias nws cov khoom siv hauv paus, titanium, yog cov khoom siv hlau zoo heev nrog lub peev xwm sib npaug qis thiab muaj lub siab nyiam rau thermodynamic corrosion hauv nruab nrab. Qhov tseeb, titanium yog qhov ruaj khov hauv ntau qhov kev tshaj tawm, xws li oxidizing, nruab nrab, thiab tsis muaj zog ntawm kev tshaj tawm. Qhov no yog vim titanium muaj kev sib raug zoo nrog oxygen. Nyob rau hauv cov huab cua los yog oxygen-muaj xov xwm, ib tug ntom, muaj zog adhesion, thiab inert oxide zaj duab xis yog tsim nyob rau saum npoo ntawm titanium, tiv thaiv titanium substrate los ntawm corrosion. Txawm tias vim muaj kev siv tshuab, nws yuav sai sai kho tus kheej los yog rov tsim dua tshiab. Qhov no qhia tau hais tias titanium yog cov hlau uas muaj lub siab nyiam mus rau passivation. Cov oxide zaj duab xis ntawm titanium ib txwm tswj tus yam ntxwv no thaum nruab nrab kub qis dua 315 ℃.
Txhawm rau txhim kho corrosion kuj ntawm titanium, kev kho deg thev naus laus zis xws li oxidation, electroplating, plasma spraying, ion nitriding, ion implantation, thiab laser kho tau tsim, uas txhim kho cov nyhuv tiv thaiv ntawm titanium oxide zaj duab xis thiab ua tiav cov kev xav tau corrosion. tsis kam. A series ntawm corrosion-resistant titanium alloys xws li titanium molybdenum, titanium palladium, thiab titanium molybdenum npib tsib xee tau tsim los ua kom tau raws li qhov xav tau ntawm cov khoom siv hlau hauv kev tsim cov sulfuric acid, hydrochloric acid, methylamine daws, high-temperature ntub chlorine gas, thiab kub chlorides. Titanium castings yog ua los ntawm Ti-32 molybdenum alloy, thiab rau ib puag ncig qhov chaw uas crevice corrosion los yog pitting corrosion feem ntau tshwm sim, Ti-0.3 molybdenum-0.8 npib tsib xee alloy yog siv, los yog Ti-0.2 palladium alloy yog siv nyob rau hauv cov khoom siv titanium, ob qho tib si. tau ua tiav cov neeg siv kev paub zoo heev.
Cov titanium alloy tshiab tuaj yeem siv tau ntev ntawm qhov kub ntawm 600 ℃ lossis siab dua. Titanium alloys TA7 (Ti-5Al-2.5Sn), TC4 (Ti-6Al-4V), thiab Ti-2.5Zr-1.5Mo yog cov sawv cev ntawm ultra-low kub titanium alloys, thiab lawv lub zog nce nrog qhov kub thiab txias, tab sis lawv plasticity hloov me ntsis. Kev tuav zoo ductility thiab toughness ntawm ultra-tsawg kub ntawm -196-253 ℃ tiv thaiv qhov txias brittleness ntawm cov ntaub ntawv hlau, ua rau nws yog ib qho zoo tagnrho cov ntaub ntawv rau kub kub ntim, cia tank, thiab lwm yam chaw.

Nta ntxiv
Txuas ntxiv rau kev ua haujlwm yooj yim thiab tseem muaj nrog gearing, lub cev muaj zog actuators, pneumatic lossis hydraulic actuators rau cov kev pabcuam nyuaj dua.
Split los yog 3-thooj, cais lub cev & lub kaus mom rau 12 "&small.disassembles yooj yim rau kev kho cov khoom.
Std packing ntau v-teflon packing, ua ke nrog nyob loading, tswj packing compression nyob rau hauv high-cycle thiab kev pab cuam heev. Graphite packing yog siv rau hightemperature.
Tshuab-tawm pov thawj qia tsim yog lub siab-zoo qia lub xub pwg tsim uas tiv thaiv tsis ua hauj lwm nyob rau hauv siab dhau.
Antistatics tsim. Kev sib cuag hlau yog ib txwm tso cai ntawm pob thiab qia / lub cev kom tso tawm qhov tshwm sim zoo li qub thaum lub sijhawm ua haujlwm.
Kev nyab xeeb hluav taws tsim los rau API607 lossis BS 6755 kom tso cai rau lawv txoj haujlwm tsim nyog thaum muaj hluav taws. Secondary hlau-rau hlau foob ua raws li thaub qab yog thawj lub foob raug puas tsuaj los ntawm hluav taws. Valves tau txiav txim kom ua raws li API 607 yuav muab nrog graphite packing thiab gaskets.
