Txhawm rau ua kom muaj kev ua kom zoo dua, yuav tsum muaj kev txhim kho los ntawm ntau yam xws li cov qauv tsim, kev tsim thev naus laus zis thiab ua tiav. Cov hauv qab no yog kev ntsuas tshwj xeeb thiab kev tshuaj ntsuam xyuas:
1. Cov Khoom Siv Daim Qauv Ua Kom Zoo
Kho cov khaub lig-txuas ceev
Txo cov nqi ntawm cross-txuas tus neeg sawv cev: ua kom muaj qhov sib txawv ntawm cov neeg tsis huv, yog li ntawd ntau qhov chaw ua si yog khaws cia ntawm molecular chains, yog li txhim kho resilience. Txawm li cas los xij, nws yog qhov tsim nyog kom tsis txhob muaj kev sib txuas tsis txaus uas ua rau cov khoom siv los ua cov nplaum lossis lub zog kom txo qis.
Xaiv cov tshuaj tsw qab heev: xws li platinum vulcanization system, uas tuaj yeem ua ib qho kev sib txuas lus sib xws, txo kev ntxhov siab hauv cheeb tsam, thiab txhim kho kev txuag hauv cheeb tsam.
Txhim kho tus muab tub lim
Txo kev txhawb nqa cov fillers: Txawm hais tias fillers xws li dawb carbon dub tuaj yeem txhim kho cov tshuab siv tshuab, ntau dhau yuav ua rau muaj kev kub ntxhov. Nws raug nquahu kom tswj tau tus nqi muab rau kev ua haujlwm raws li cov kev xav tau (xws li tus nqi ntawm cov pa roj hmab dub ntxiv dua lossis muaj sib npaug rau 30phr).
Siv cov fherical fobers: kheej kheej ferters (xws li nano-silica) muaj cov kev txav ntawm cov ntxiab molecular dua rab koob, uas pab kom muaj kev tswj hwm.
Ntxiv Elastomer Modifiers: piv txwv li, kev sib xyaw ua ke roj hmab nrog ethylene-acrylate roj hmab tuaj yeem qhia cov ntu kev hloov kho tau yooj yim.
Xaiv cov viscosity tsawg silicone
Siv cov roj me me, qis-viscosity silicone roj yog qhov pib polymer, ua rau nws yooj yim dua tom qab tau ntxhov siab.
2. Kev tswj hwm
Cov txheej txheem vulcanization kev ua kom zoo
Tswj lub vulcanization kub thiab sijhawm: tsis txaus vov neeg yuav ua rau cov neeg tsis txaus siab ntom ntom ntom thiab cov neeg txom nyem; Ntau tshaj plaws vertaneization yuav ua rau molecular chart breakage. Qhov kev ua kom zoo nkauj zoo tshaj plaws yuav tsum tau txiav txim siab sim (xws li platinum vulcanization tshuab feem ntau yog vulcanized ntawm 120-17 feeb).
Siv ob-theem vulcanization: ib theem vulcanization (kub ceev prototyping) ua raws li ob-theem kev siv tshuaj dawb (tsawg kub sai sai) tuaj yeem tshem tawm sab hauv kev ntxhov siab thiab txhim kho kev ntxhov siab sab hauv.
Sib xyaw ua ke
Xyuas kom meej tias fitters, volcanizers thiab lwm yam ntxiv yog tusyees dispersed hauv silicone kom tsis txhob muaj kev ua tau zoo hauv zos. Sab hauv tov khoom lossis qhib tov khoom yuav siv tau rau ntau yam sib xyaw, kom tsis txhob muaj qhov kub thiab txias rau kev sib xyaw ntawm cov roj ntau yam ntawm cov roj ntau yam ntawm cov neeg sawv cev sib cav sib ceg).
Txheeb thiab Kev Ua Haujlwm Tom Qab
Siv High-efficiing demoulding tus neeg sawv cev kom txo cov demoulding tsis kam thiab tsis txhob muaj kev ntxhov siab sab hauv ntawm cov ntaub ntawv.
Kev kho cua sov ntawm vulcanized silicone (xws li baking ntawm 150℃rau 2 teev) tuaj yeem tso tawm sab hauv kev ntxhov siab thiab txhim kho kev ntxhov siab ntxiv.
III. Kev Tsim Kho Txheej Txheem
Txhim kho cov khoom lag luam
Zam kev ua kom ntse lossis cov qauv sib dhos nyias cov txheej txheem kom txo cov ntsiab lus ntxhov siab. Piv txwv, hloov cov ces kaum sab xis kom sib dhos cov ces kaum tuaj yeem txo cov kev deformation hauv cheeb tsam thaum raug yuam thiab txhim kho cov khaub ncaws tsis sib thooj.
Tsim hollow qauv qauv lossis honeycomb cov qauv los txo cov rigidity los ntawm kev txo cov khoom siv thaum tswj cov kev tswj hwm tag nrho.
Ntxiv Cov Txheej Txheem
Ntxiv ib txheej txheej txheem tsis sib xws (xws li ua npuas ncauj, caij nplooj ntoos hlav) nyob rau saum npoo lossis sab hauv ntawm lub zog silicone, thiab yog li indireone lub cev, thiab yog li indirecone lub cev, thiab yog li indireone lub cev, thiab yog li indireone lub cev, thiab yog li ua kom ncaj qha txhim kho kev quab yuam.
IV. Kev Ua Si Tom Qab thiab Kev Hloov Deg
Nto Txheej
Ua ntawv thov roj silicone lossis cov txheej txheem fluorine tuaj yeem txo cov coeffication ci, txo lub zog poob thaum raug quab yuam, thiab txhim kho rov qab ua haujlwm.
Kev Hloov Rau Lub Cev
Los ntawm kev sib sau cov txheej ntom ntom ntawm silicone los ntawm kev hla kev hla kev (xws li hluav taws xob nqaj tuaj yeem raug txhim kho thaum tswj cov sab hauv.
5. Thov kom cov xwm txheej kev yoog raws
Tswj Qhov Kub
Zam txhob siv Silicone hauv qhov chaw kub tsawg (xws li qis dua -40 Degree), vim tias tsawg dua yuav cuam tshuam kev txav ntawm cov molecular charts thiab cuam tshuam kom muaj kev tiv thaiv ntau. Yog tias yuav tsum tau cov ntawv thov kub tsawg, mob khaub thuas-resistant silicone (xws li Phenyyl Silicone Roj Hmab) Yuav Xaiv.
Nruab Nrab Kev Noj Qab Haus
Yog tias silicone yuav tsum tau hu rau roj, kua qaub, alkali thiab lwm yam xov xwm tiv thaiv fluorone (lossis nruab nrab yuav tsum tau raug rho tawm los ntawm cov txheej txheem fluoroone (xws li cov roj hmab kom tiv thaiv kom tsis txhob muaj kev tiv thaiv vim qhov o lossis kev cuam tshuam.
6. Kev sim ua pov thawj thiab iteration
Kev sim nrhiav kev xeem
Siv tus tub tes taw rov ua haujlwm (xws li Shaw tus tub luam rov qab) lossis pob poob poob rau ntau tus nqi ntawm Silicone (qhov sib piv ntawm rebound qhov siab mus poob qhov siab).
Piv cov rackound tus nqi nyob rau hauv cov qauv sib txawv lossis cov txheej txheem los xaiv cov tshuaj zoo tshaj plaws.
Kev ntsuas ncua ntev ntev
Ntsuas cov kev ua tiav ntawm kev rov ua dua ntawm silicone los ntawm kev ntsuas nkees (xws li rov ua kom cov khoom siv tau ua tau zoo hauv kev siv ntev.
Piv txwv cov qauv thiab txheej txheem
Muaj peev xwm resilience silicone misula:
Lub hauv paus Polymer: 100phr qis viscosity Dimethyl Silicone Roj (molecular hnyav 50,00000,000)
Muab tub lim: 20RHR fumed silica (nto kho nrog cov neeg ua haujlwm coupling tus neeg sawv cev)
Vulcanizer: 0.5phr Platinum catalyst (suav nrog cov neeg ua kom muaj kev tiv thaiv)
Tus neeg saib xyuas: 1phr hydroxy Silicone Roj (los kho FLUCTION)
Siv Tshuab:
Kev sib xyaw: sib xyaw hauv kev sib xyaw sab hauv ntawm 120℃rau 10 feeb, thiab thinning hauv kev ua si qhib 3 zaug.
Vulcanization: 150 Qeb Moulded Vulcanization rau 15 feeb, thiab qib thib ob vulcanization ci ntawm 180℃rau 4 teev.
Kev khomob tom qab kho: Thov ntuit hniav fluorine rau saum npoo kom txo cov kev txhuam hniav.
Los ntawm cov kev ntsuas saum toj no, tus nqi rov qab los ntawm silicone tuaj yeem nce mus rau cov xwm txheej ua si, xws li cov khoom siv kis las, thiab kho tshuab kho mob.
