Vim li cas cov neeg muab khoom qee zaum hloov cov khoom siv
Kev nkag siab txog tus neeg muag khoom qhov kev xav pab cov neeg yuav khoom kom tsis txhob muaj cov khoom tsis sib haum. Muaj peb yam xwm txheej uas tus neeg muag khoom yuav sib txawv ntawm cov khoom siv:
1. Hloov SUS304 rau SUS301 kom txuag tau nqi.Yog tias tus neeg yuav khoom tsis qhia meej SUS301 thiab tsuas yog hais tias "stainless steel dome," qee tus neeg muag khoom yuav siv pheej yig dua SUS304 sawb. Lub dome yuav dhau qhov pib quab yuam thiab qhov ntsuas qhov ntsuas, tab sis yuav ua tsis tiav ntxov hauv kev pabcuam. Ib txwm qhia "SUS301 tag nrho nyuaj" los ntawm lub npe, tsis yog "stainless steel."
2. Siv softer temper los ntaus lub hom phiaj uas tsis muaj zog.Yog tias tus neeg yuav khoom thov lub zog qis qis (qis dua 100g) rau lub dome me, tus neeg muag khoom yuav siv cov khoom siv softer 1/2H lossis 3/4H es tsis txhob optimizing lub dome geometry. Qhov tshwm sim yog lub dome uas pom tau tias yog thawj zaug tab sis tsis zoo tactile piv thiab lub neej luv luv. Zoo dua los tsim ib lub dome loj dua, thinner dome nyob rau hauv tag nrho cov ntaub ntawv nyuaj dua li siv cov khoom muag.
3. Mill kev txwv.SUS316 nyob rau hauv ultra- ntsuas nyias (0.05–0.08mm) thiab tempers meej tsis yog ib txwm yooj yim. Tus neeg muag khoom tuaj yeem hloov cov qib zoo sib xws lossis kev kub ntxhov. Qhov no siv tau yog tias tau sau tseg thiab rov- tsim nyog, tab sis nws yuav tsum tsis txhob tshwm sim ntsiag to. Nug koj tus neeg muag khoom rau daim ntawv qhia txog kev xeem zeb (MTR) nrog rau txhua yam khoom siv, qhia qhov tseeb qib, tus naj npawb cua sov, thiab hardness.
Cov khoom siv cuam tshuam li cas rau lwm yam Dome Properties
Kub rhiab heev
Stainless hlau poob lub zog tensile thaum kub nce. SUS301 tag nrho nyuaj ntawm +85℃tej zaum yuav pom 10-15% qis actuation quab yuam tshaj ntawm chav tsev kub. Ntawm -40 degree, quab yuam nce 5-10%. Qhov no yog qhov qub thiab kwv yees tau, tab sis nws tseem ceeb yog tias koj cov khoom yuav tsum ua haujlwm thoob plaws qhov kub thiab txias - qhia lub zog ntawm qhov kub thiab txias, tsis yog chav tsev kub xwb. SUS304 yog qhov kub thiab txias me ntsis, tab sis ntawm tus nqi qis zog. SUS316 coj zoo ib yam li SUS301 thermally.
Plating Adhesion
Cov khoom saum npoo av ncaj qha cuam tshuam rau plating adhesion. SUS301 ua hauj lwm- cov sawb tawv tawv muaj cov chromium ib txwm muaj passivated- nplua nuj nto uas lees txais npib tsib xee thiab kub plating zoo. Txawm li cas los xij, yog tias cov sawb tau raug kho nrog roj lossis cov ntiv tes ua ntej plating, adhesion tsis ua haujlwm. Qhov no yog cov txheej txheem tswj qhov teeb meem es tsis yog qhov teeb meem ntawm qib khoom, tab sis nws pom tau ntau dua ntawm kev kub ntxhov uas qhov roughness qis dua.
Dome Life vs. Material Thickness
Rau lub dome txoj kab uas hla thiab quab yuam, cov khoom thicker nyob rau hauv lub softer temper yuav muaj lub neej luv dua li cov khoom thinner nyob rau hauv ib tug nyuaj temper. Qhov no zoo li qhov tsis txaus ntseeg tab sis ua rau muaj kev nkag siab: qhov kev qaug zog tsis ua haujlwm yog tawg ntawm qhov khoov lub vojvoog, thiab ib qho thinner, nyuaj dome muaj kev ntxhov siab tsawg dua ntawm lub vojvoog. Thaum thovkev cai dome arrays, nug tus neeg muag khoom kom pom zoo rau lub ntsuas qhov nyias nyias uas ua tau raws li koj qhov kev xav tau ntawm lub zog tag nrho -SUS301 nyuaj es tsis ua rau lub ntsuas tuab, softer.
Dab tsi los muab tso rau hauv koj RFQ thiab Kev Txiav Txim
Txhawm rau kom tsis txhob muaj cov khoom tsis meej, suav nrog cov khoom tshwj xeeb no hauv koj lub dome specification thiab PO:
- Cov ntaub ntawv qib: "SUS301 tag nrho nyuaj" - tsis yog "stainless hlau." Rau corrosion- daim ntawv thov tseem ceeb: "SUS316 tag nrho nyuaj."
- Temper thiab hardness: Qhia ob qho tib si temper designation (H) thiab Rockwell lossis Vickers hardness range (xws li, HV 550–600). Qhov no tiv thaiv tus neeg muag khoom los ntawm kev hloov lub siab softer.
- Khoom thickness kam rau ua± 10% ntawm nominal thickness. Thickness variation yog qhov loj tshaj plaws contributor rau quab yuam variation ntawm ntau ntau.
- Mill Test Report (MTR): Yuav tsum tau MTR nrog rau txhua qhov khoom xa tuaj qhia qib, tus naj npawb cua sov, lub zog tensile, thiab hardness. Nov yog koj cov ntaub ntawv traceability.
- Kev hloov khoom siv tau txais: Yog tias tus neeg xa khoom xav tau hloov pauv (piv txwv li, SUS304L tsis yog SUS304), yuav tsum tau sau ntawv ceeb toom thiab rov ua dua - kev xeem ntawv tsim nyog - yeej tsis lees txais qhov hloov pauv ntsiag to.
