Li cas los xaiv txoj caiPolyurethane pwm?
Polyurethane tau dhau los ua ib qho ntawm cov ntaub ntawv cog lus tshaj plaws hauv cov khoom siv pwm niaj hnub. Raws li qhov tshiab -} tiam elastomeric polymer, nws muab cov roj hmab zoo sib xws ntawm kev hloov pauv thiab lub zog. Nyob rau hauv xyoo tsis ntev los no, nws siv hauv pwm rau iasostatic nias, ceramics, thiab hmoov metallurgy tau loj hlob sai vim nws lub neej zoo thiab lub neej ntev.
Qhov Zoo Qhov Zoo ntawm Polyurethane Moulds
1. Cov khoom siv lub cev thiab cov kws kho tshuab
Polyurethane kev pov thawj zoo dua rau cov roj, siab, hnav, kua muag, thiab oxidation.
Piv nrog cov tsoos pwm cov khoom siv xws li roj hmab lossis hlau, polyurethane muab sijhawm pab ntau dua, thiab tsawg dua deormation raws li kev ntxhov siab ntxiv. Cov yam ntxwv no ua rau nws tsim nyog rau cov ntawv thov xws li txias iextatic nias (CIE {1} pre} precision ua cov txheej txheem.
2. Dav tau kho hardness ntau
Ib ntawm Polyurethane qhov ua tau zoo tshaj plaws yog nws cov khoom siv dav dav. Nws lub hardness tuaj yeem hloov kho tau meej los ntawm ntau cov mos mos (ntug dej ib 20) rau kev nyuaj (ntug dej D 70 lossis siab dua) nyob ntawm qhov yuav tsum tau ua.
Qhov kev ua tau zoo no tso cai rau polyurethane pwm kom tau customized rau cov khoom sib txawv thiab cov kev mob siab} Muab cov hlau sib xyaw los ntawm cov hlau lossis cov pwm sib xyaw.
3. Cov lus tso tawm tshiab thiab anti -} sticking cov khoom
Polyurethane pwm muab elasticity zoo heev thiab du zoo nkauj, uas txhim kho kev ua kom zoo.
Piv nrog Silicone pwm, polyurethane pwm tsis tshua muaj khoom siv cov khoom nplaum, nrawm dua, thiab ntau dua. Qhov txiaj ntsig no yog qhov tseem ceeb hauv cov loj- nplai lossis txuas ntxiv kev tsim khoom lossis kev ua haujlwm txuas ntxiv thiab kev ua tiav nto yog qhov tseem ceeb.
Cov teeb meem thiab kev daws teeb meem hauv polyurethane pwm siv
1. Txhaum lossis nyuaj dauv
Qhov teeb meem no yuav tshwm sim yog tias cov txheej txheem tsis yog tsis tsim nyog. Kev daws suav nrog:
Txo kev txhaj tshuaj lossis tuav siab.
Txhim kho cov txheej txheem moulding thiab kho cov khoom lossis puab cov ntsuas kub.
Kev kuaj xyuas thiab kho cov hluav taws xob lub kaum sab xis ntawm cov pwm kom ntseeg tau yooj yim.
Kev thov kom tsim nyog ntawm cov neeg sawv cev pwm tuaj yeem pab txo qis qis.
2. Machining thiab Kev Ua Kev Nyuaj Siab
Cov ntaub ntawv polyurethane tuaj yeem yog machined nrog siab- Cov cuab yeej ceev ceev uas muaj lub tog ceev thiab tshem tawm cov ces kaum.
Thaum lub sijhawm machining, nws yog ib qho tseem ceeb uas yuav tau xav txog theem nyuaj ntawm polyurethane thiab kho kev txiav ceev, pub tus nqi noj mov raws li.
Yog li cov txiaj ntsig zoo tshaj plaws, cov pwm saum npoo av yuav tsum polished thiab kho kom ua tiav kom meej meej meej meej.
