Kev tsim khoom txheej txheem ntawm Silicone Ua Npuas
Tsis zoo siv
Silicone ua npuas ncauj yog ib qho ntau yam paub rau nws lub teeb yuag, cov cuab yeej ntxeem, thiab tshuaj lom neeg kuj. Kab lus no muab cov ncauj lus kom ntxaws ntawm covKev tsim khoom, cov txheej txheem tseem ceeb, thiab kev lag luam cov ntawv thovNtawm silicone ua npuas ncauj, nrog rau kev tawm tshiab tshaj tawm nyob rau hauv cov tshuab ntau lawm.
1. Pib
Silicone ua npuas yog lub cellular elastomer tsim los ntawm kev qhia cov roj npuas ua ke nrog cov roj hmab silicone, ua rau cov roj hmab silicone thiab lub zog tsis muaj zog thiab nqus tau ntawm ua npuas ncauj. Nws yog dav siv nyob rau hauv kev lag luam xws liCov Khaub Ncaws (piv txwv, khiab mis pads), khoom kho mob, tsheb, thiab hluav taws xobVim nws cov khoom tshwj xeeb.
2. Cov ntsiab lus tseem ceeb ntawm Silicone Ua Npuas Ncauj
2.1 Cov Khoom Siv Raw
| Ib feem | Rooj mov | Hom Hom Hom Hom |
|---|---|---|
| Silicone Base | Thawj Elastomer Matrix | VMQ (Vinyl Methyl Silicone) |
| Tshuab tus neeg sawv cev | Tsim cov roj av kom tsim cov hws | Azodicarbonamide (Tshuaj) |
| Tus neeg sawv cev hla tus neeg sawv cev | Txhawb nqa kho | Peroxide (piv txwv, DCP) |
| Cov fillers | Hloov kho cov tshuab / thermal Khoom | Silica, carbon dub |
| Catalysts / inhibitors | Kev tswj hwm kho & ua npuas dej | Platinum catalysts |
3. Kev tsim qauv
3.1 Ua npuas ncauj tshuaj lom neeg
Txheej Txheem Kauj Ruam:
Kev sib xyaw: Silicone puag, tus neeg sawv cev, thiab cov quav ntxiv tau sib xyaw ua ke hauv kev sib xyaw sab hauv.
Moulding / Extrusion: Cov sib tov yog muab tso rau hauv cov pwm lossis extruder thiab rhuab (150-200 degree).
Foaming & Kho: Lub tshuab tus neeg sawv cev decomposes, tso roj (n₂ los yog sib zog), thaum crosson crosslinks los ua tus qauv ua npuas ncauj ruaj khov.
Qhov Zoo:
Nqi them tus nqi rau huab hwm coj ntau lawm (piv txwv li, khiab mis pads).
Adjustable Pore loj (0.1-2 mm).
3.2 Foaming Lub Cev
Txheej Txheem Kauj Ruam:
Roj txhaj: Supercritical kua dej (piv txwv li, CO₂) yog yaj mus rau Silicone nyob rau hauv kev kub siab.
Siab tso: Saipressurization nthuav tawm cov roj, tsim cov microcellular ua npuas.
Kev kho: UV lossis cov thermal kho kom ruaj khov tus qauv.
Qhov Zoo:
Uniform micropores (<100 µm).
Eco-phooj ywg (tsis muaj kab mob tshuaj).
3.3 Foaming tshuab
Huab cua lossis iner roj yog whipped rau hauv cov kua silicone, ua raws li los ntawm kev kho.
Cov Ntawv Thov: Tsawg-ntom ntom ntom (piv txwv li, txha hniav insoles).
4. Cov txheej txheem tseem ceeb
| Chaw ua uas tsis tau haus | Hloov | Kev ua kom ua kom zoo |
|---|---|---|
| Tshuab Tus Neeg Sawv Cev piv | Txiav txim siab porosity (5-80%) | 3-10% rau feem ntau cov ntawv thov |
| Qho so | Cuam tshuam rau cov foaming tus nqi & kev sib dhos | Multi-Xyaum Tswj Cua Kub |
| Kho lub sijhawm | Nyob rau hauv-cathing weakens; Tshaj-kho collapses ua npuas ncauj | Kev sim-ua kom tau zoo |
| Chais Xaiv | Txhim Kho Lub Zog / Conductivity | Nano-fillers rau kev ua haujlwm siab |
5. Kev lag luam khoom lag luam
5.1 Apparel & Textiles
Lub khob noom bra: Lub teeb yuag, ua pa ua npuas pads (0.3-0.5 g / cm³).
Sportswear: Ua npuas ncauj silicone padding rau kev cuam tshuam.
5.2 pab kiag li lawm
