Ib qho: Cov khoom tseem ceeb ntawm cov roj dimethicone Dimethicone yog cov kab oligosiloxane nrog cov tshuaj formula (CH3)3SiO[(CH3)2SiO]nSi(CH3)3. Nws muaj cov tshuaj zoo, thermal, mechanical, hluav taws xob insulating thiab biocompatibility. Dimethicone yog cov tshuaj tsis muaj tshuaj lom, tsis muaj ntxhiab, tsis muaj xim, thiab tsis muaj nplaim taws. Nws muaj cov khoom tsis tshua muaj zog, tsis muaj suab nrov thiab lubric dej zoo thiab yog ib qho tseem ceeb siav nplua nuj.
Ob: Lub tswv yim ntawm viscosity thiab unit viscosity yog cov cuab yeej ntawm cov kua los tiv thaiv deformation txav sab hauv. Qhov ntau dua qhov viscosity, qhov ntau dua qhov tsis kam ntws thiab rov ua dua. Viscosity yog ntsuas nyob rau hauv pastecoseconds (Pa·s) thiab tuaj yeem qhia ua millipascals me (mPa·s). Hauv kev lag luam, feem ntau siv viscosity units suav nrog tus lej heptanetriane (cSt) thiab phaus-seconds/in² (lb·s / in²).
Peb: Daim ntawv thov thiab qhov sib txawv nyob rau hauv txawv viscosities
1. Tsawg viscosity dimethicone roj (10-100cSt): Tsawg viscosity dimethicone roj muaj fluidity zoo thiab volatility, thiab feem ntau yog siv nyob rau hauv sib tsoo kua, luam ntawv inks, zaub mov additives thiab lwm yam teb. Nws muaj peev xwm txaus txaus tso cai rau nws los txhim kho cov txheej txheem kev ua tau zoo mus rau qhov zoo.
2. Medium viscosity dimethicone roj (100-1000cSt): Nruab nrab viscosity dimethicone roj yog dav siv hauv tsev thiab kev lag luam, xws li cov khoom siv tu tawv nqaij, tshuaj pleev plaub hau, tshuaj pleev thaiv hnub, tshuaj pleev ib ce, kua nplaum, luam ntawv inks, latex xim thiab lwm yam. teb. Nws cov khoom lubricating thiab tshuaj stability yog zoo.
3. High viscosity dimethicone roj (1000-10000cSt): High viscosity dimethicone roj yog siv nyob rau hauv high-temperature sealing cov ntaub ntawv, hluav taws xob tivthaiv cov ntaub ntawv ntim, xim thickeners, adhesives, pwm polishing agents thiab lwm yam teb. Nyob rau hauv qhov kub thiab txias, nws viscosity tsis yooj yim hloov, thiab nws muaj qhov kub thiab txias tsis kam. Hauv kev xaus, cov kua dej dimethicone nrog cov viscosities sib txawv muaj cov kev siv thiab cov khoom sib txawv. Xaiv qhov zoo viscosity yog qhov tseem ceeb heev rau kev tsim khoom thiab kev siv. Thaum siv, nws raug nquahu kom xaiv qhov tsim nyog viscosity raws li cov ntawv thov tshwj xeeb, thiab siv nws ntawm qhov kub thiab txias kom muab kev ua si tag nrho rau nws qhov kev ua tau zoo thiab txhim kho kev tsim khoom thiab cov khoom zoo.
