Dab Tsi Yog Qhov Tshaj Tawm Thiab Siv Ntawm Cov Mos Mos?

1. Kub tsis kam

Cov khoom siv roj silicone ua raws li cov ntawv cog lus silicon-oxygen (Si-O). Kev sib zog lub zog ntawm CC daim ntawv cog lus yog 82.6 kcal / g qauv, thiab lub zog sib zog ntawm cov nyiaj Si-O yog 121 kcal hauv silicone. / gram lwg me me, yog li cov khoom lag luam silicone muaj qhov ua kom zoo thermal stability, thiab cov ntawv cog lus tshuaj ntawm cov molecules thaum muaj qhov kub (lossis hluav taws xob) tsis tawg lossis rhuav tshem. Silicone tsis tsuas tiv taus huab cua sov, tab sis kuj tiv taus kub thiab tsis tshua muaj siab thiab tuaj yeem siv dhau ntau qhov kub thiab txias. Txawm hais tias nws yog tshuaj lom neeg los yog lub cev ua rau lub zog, nws txawv me me nrog qhov ntsuas kub.

2. Huab cua tsis kam

Lub saw tseem ceeb ntawm cov khoom siv silicone yog -Si-O-, uas tsis muaj ob txoj hlua khi thiab yog li tsis yooj yim decomposed los ntawm ultraviolet teeb thiab ozone. Silicones muaj zoo dua thermal stability thiab tiv taus hluav taws xob thiab huab cua dua li lwm cov ntaub ntawv polymer. Cov kev pab cuam lub neej ntawm silicone nyob rau hauv lub ntuj puag ncig tuaj yeem ncav cuag ntau xyoo lawm.

3. Kev ntsuas hluav taws xob ua haujlwm

Cov khoom ua kua hluav taws xob muaj cov hluav taws xob zoo hluav taws xob tiv thaiv, thiab lawv cov hluav taws xob tsis zoo, tiv taus voltage, arc tsis kam, corona tsis kam, ntim resistivity thiab nto resistivity yog cov zoo tshaj plaws hauv cov ntaub ntawv insulating, thiab lawv cov khoom siv hluav taws xob tau cuam tshuam los ntawm qhov kub thiab zaus. Qhov kev cuam tshuam yog me me. Yog li ntawd, lawv yog cov hluav taws xob ruaj khov insulating khoom siv thiab yog siv dav hauv cov khoom siv hluav taws xob thiab hluav taws xob. Ntxiv rau kev tiv thaiv kev kub nyhiab zoo, silicone muaj cov dej zoo heev, uas yog qhov lees tias muaj kev ntseeg siab ntawm kev siv cov khoom hluav taws xob hauv qab ntub.

4. Lub cev muaj zog inertia

Polysiloxanes yog ib qho ntawm cov khoom siv tsis muaj zog. Lawv tiv taus kev laus lom, tsis muaj kev tsis lees txais nrog tsiaj, thiab muaj cov khoom zoo anticoagulant.

5. Tsis tshua muaj qhov nro thiab cov nplaim hluav taws xob tsawg

Lub ntsiab saw ntawm silicone yog yoog heev, thiab nws lub zog intermolecular muaj ntau tsis muaj zog tshaj qhov uas ntawm hydrocarbons. Yog li ntawd, nws qis dua nyob rau hauv viscosity dua li hydrocarbons ntawm tib lub cev nyhav, muaj qhov tsis sib thooj ntawm qhov muag, lub zog me me, thiab cov zaj duab xis muaj zog muaj peev xwm. Qhov no tsis tshua muaj qhov siab thiab lub ntsej muag tsis tshua muaj lub zog yog qhov laj thawj tseem ceeb rau nws daim ntawv thov siv ntau: hydrophobic, defoaming, ua npuas dej khov, tiv thaiv kev cuam tshuam, tiv thaiv lub hauv siab, lubrication, siab thiab lwm yam zoo heev.
