Silicone keypads, tseem hu ua silicone nyees khawm los yog organosilicon keypads, yog cov khoom tseem ceeb ua los ntawm silicone roj hmab (mSiO₂·nH₂O). Lawv muaj cov yam ntxwv xws li kub tsis kam (-20℃txog 180 degree), txias tsis kam, hluav taws xob rwb thaiv tsev, thiab qaug zog tiv thaiv. Tsis muaj tshuaj lom, tsis muaj ntxhiab, thiab muaj tshuaj lom neeg ruaj khov, lawv tau siv dav hauv cov neeg siv khoom siv hluav taws xob xws li lub laij lej, cov chaw taws teeb tswj, thiab cov keyboards hauv computer, thiab tau nthuav dav mus rau hauv kev lag luam xws li kev siv tshuab cua txias thiab khoom siv kho mob.

 

Raws li qhov siab, lawv tau muab faib ua plaub theem: 50-80g (lub tshuab xam zauv), 80-120g (cov chaw taws teeb tswj), 120-180g (cov cuab yeej lag luam), thiab tshaj 180g (kev lag luam tshwj xeeb). Lawv tuaj nyob rau hauv ntau tshaj 20 hom, suav nrog ib leeg-taw tes, conductive, thiab translucent, nrog lifespans xws li 0.5 txog 30 lab keystrokes. Cov txheej txheem ntau lawm yuav tsum tau tswj qhov kub thiab txias thiab pwm tso tawm cov txheej txheem los tiv thaiv kev tawg, thiab high-precision laser engraving yog siv los ua kom tiav cov cim translucent, txhim kho pom kev hmo ntuj. Cov khoom lag luam muaj kev tiv thaiv kev tiv thaiv tsawg dua 150Ω thiab lub zog rwb thaiv tsev ntawm 25-30kV / mm, ua rau nws tsim nyog rau cov pob xav tau ntawm ntau yam khoom siv hluav taws xob.

 

Silicone gel (tseem hu ua silicone roj hmab) yog cov khoom siv adsorbent uas muaj zog heev, cov tshuaj amorphous nrog cov tshuaj formula mSiO2·nH2O. Nws yog insoluble hauv dej thiab ib qho hnyav, tsis yog - tshuaj lom, tsis muaj ntxhiab, thiab tshuaj lom neeg ruaj khov, ua rau tsis muaj tshuaj tshwj tsis yog muaj zog alkalis thiab hydrofluoric acid. Ntau hom silica gel muaj cov qauv microporous sib txawv vim lawv txoj kev tsim khoom sib txawv. Cov tshuaj lom neeg muaj pes tsawg leeg thiab lub cev qauv ntawm silica gel muab ntau yam ntxwv uas nyuaj rau lwm cov ntaub ntawv zoo sib xws los hloov: siab adsorption muaj peev xwm, zoo thermal stability, tshuaj stability, thiab siab mechanical zog. Silicone gel yog cais raws li nws qhov pore loj rau hauv: macroporous silica gel, coarse -pore silica gel, hom B silica gel, thiab nplua - pore silica gel.
