Vim li cas cov kua siicone roj hmab pob tshab lossis ib nrab pob tshab?
Lub hauv paus rau phau ntawv
Kua Silicone Roj Hmab (LSR) yog ib qho ntau ntxiv dav siv hauv kev kho mob, kho kho kom zoo nkauj, thiab cov khoom siv hluav taws xob zoo heev, thiab yoog raws thiab yooj. Ib qho ntawm nws cov yam ntxwv uas tsim nyog yog nws cov lus pob lossis ib nrab pob tshab, xws li lo ntsiab muag, muab cov ntsaws ruaj ruaj, thiab cov khoom siv kho mob. Cov ntawv no tshawb nrhiav qhov tseem ceeb tseem qab LSR cov pob tshab.
1. Amorphoud molecular qauv
Tsis zoo li crystalline polymers uas scatter teeb vim lawv tau xaj molecular kev npaj, LSR yog tsim ntawmpolysiloxanes(piv txwv li, PDMS - polydimethylsiloxane), uas muaj ib qhoAmorphous (tsis-crystalline) qauvCov. TusSi-O-Si Bycleneyog heev hloov tau, nrog cov ntawv cog lus ntev ntev thiab cov ces kaum loj, tso cai rau cov saw polymer kom txav mus dawb. Qhov kev tsis sib haum xeeb no minimizes lub teeb tawg, uas ua rau pob tshab.
2. Qis hla kev sib txuas ntom ntom ntom ntom ntom
LSR Curse ntawm ib qho platinum-catalyzed hydrosilylation tshuaj tiv thaiv, sib sau ua peb-seem network. Txawm li cas los xij, tusHla-txuas ntom ntom yog qhov tsawg, txhais tau cov saw hlau polymer khaws cov ntsiab lus tseem ceeb ntawm cov ntsiab lus txuas sib txuas. Qhov no txwv tsis pub muaj kev tsim cov av ntom, cov cheeb tsam tawg, tswj xyuas cov kev paub zoo saib xyuas qhov tseeb.
3. Cov Purity thiab Tsawg Tshaj Plaws Ntxiv
Tsis muaj cov sau los yog pigments: Tsis zoo li cov khoom siv silicone
Ultra-ntshiab zog: Lub hauv paus silicone polymers thiab cov tshuaj tua kab yog kev lim hiam, txo cov impurities uas tuaj yeem nqus tau lossis lub teeb scatter.
4. Cov Hom Teeb Ua Haujlwm
Rau cov khoom siv los ua pob tshab, nws cov khoom siv yuav tsum muajSib txuam ua cov khoom siv tsis tu ncuaCov. Hauv LSR:
Lub hauv paus silicone thiab cross-txuas muaj cov khoom siv tsis zoo sib xws (~ 1.40-1.43).
Ib qho twg ntxiv nanoparticles (piv txwv li, fumed silica rau qhov cuab lub zog) muaj ntau dua li pom lub teeb (<50 nm), preventing significant light scattering.
5. Ua cov txiaj ntsig zoo
Npuas-dawb moulding: LSR qhov viscosity tsawg zam nws kom sau moulds zoo, txo cov pa hluav taws xob plhaw pa uas yuav ua rau hazhe.
Tsawg-Kub Kho: Tsis zoo li kub npau taws (HTV) silcanization (lsr cures ntawm qhov kub kub khov kho, tiv thaiv kev cuam tshuam thermal lossis daj.
Yam uas tuaj yeem txo cov pob tshab
Thaum LSR yog pob tshab, qee yam kev hloov kho tuaj yeem txo cov ntsiab lus meej:
Ntxiv cov fillaque(piv txwv li, titanium dioxide, carbon dub).
Siab hla-txuas kev ntom ntom ntom ntom, ua rau kev sib cais microphase.
Tsis raug cai, ua rau cov npuas lossis paug.
Cov ntawv thov ntawm pob tshab lsr
Vim nws cov khoom kho tshiab, LSR siv nyob rau hauv:
✔ Cov Khoom Siv Kho Mob(pob tshab tubing, ua pa lub khob noom).
✔ Cheebtsam Optical(Lens gaskets, cov lus qhia teeb).
✔ Cov Neeg Siv Khoom Electronics(Mos-kov keypads, waterproof ntsaws ruaj ruaj).
✔ LED Encapsulation(Tiv thaiv cov coj thaum tswj kev kis lub teeb).
Tag
Cov pob tshab ntawm cov kua silicone roj hmab stems los ntawm nwsAmorphous Txuj Ci, Qis Hla-Txuas Nrig Nrig, Siab Purity, thiab Ua kom tsis muaj kev sib sau ua keCov. Los ntawm kev ua tib zoo tswj cov kev tsim qauv thiab kev tsim ua, cov tuam ntxhab tuaj yeem ua kom LSR's kho qhov muag khoom rau cov ntaub ntawv pom tseeb, kav ntev, thiab hloov tau.
