Silicones muujiyaan astaamo badan oo waxtar leh

Silicones muujiyaan astaamo badan oo waxtar leh, oo ay ku jiraan: [1]
conductivity kaamerada Low
falcelin kiimikada Low
sumoobo Low
xasiloonida kulul (niyo ah oo guryaha ka badan kala duwan heerkulka balaadhan oo ah -100 250 ° C).
Awoodda in ay kada biyaha iyo foomka shaabadood ku xaraysid.
Ma ku eekaan muhashada badan, laakiin dhaqmayso si aad u wanaagsan in dadka kale, tusaale ahaan dhalooyinka.
Ma taageeraan koritaanka microbiological.
Resistance si oxygen, Allena, ultraviolet iftiinka iyo (UV). Hantida Tani waxa ay keentay in isticmaalka baahsan ee silicones in industry dhismaha (sida blaastiigga, ka hortagga dabka, shaabadood glazing) iyo suuqa baabuurta (gaskets dibadda, goo external).
Guryaha ningax korontada. Maxaa yeelay, silicone loo diyaariyey kartaa in ay koronto insulative ama tabinta, waxaa haboon tiro balaadhan oo ah codsiyada korontada waa.
Permeability gaaska High: heerkulka qolka (25 ° C), permeability ee caag silicone for gaasas sida oxygen waa qiyaastii 400 jeer [yeerida loo baahan yahay] in caag butyl, samaynta silicone waxtar u leh codsiyada caafimaad, taas oo kor u tuulista la doonayo. Taa waxaa ka duwan, masaxado silicone looma isticmaali karo meesha shaabadood gaas-dhagan yihiin lagama maarmaan.
Silikoon la soo saari karaa galay baco caag, halkaas oo wuxuu leeyahay sifooyin kale, sida in ay waafaqsan FDA. Tani kordhiyay isticmaalka bacaha silicone in warshadaha in ay dalbadaan nadaafadda, tusaale ahaan, cuntada iyo sharaabka iyo dawooyinka.
