Imibuzo Evame Ukubuzwa

Ngokuvamile, i-silicone inikeza ukuvikela okuhle kakhulu futhi ivame ukusetshenziswa ezimotweni, ezintweni zikagesi, nasemishinini emikhulu ukuvimba ugesi kanye nokushisa. Kodwa-ke, uma ezinye izinto, njengekhabhoni evame kakhulu yokuqhuba, zengezwa ku-silicone, i-silicone ingaphinde ifeze umsebenzi wokuqhuba, one-conductivity enhle kakhulu. Ivame ukusetshenziselwa izinhlelo zokusebenza ezifana nokuvala ukuphazamiseka kwe-electromagnetic, ukuvala ingcindezi, kanye nokuvala imvelo.

Ama-polymer afana nerabha ye-silicone ayancipha uma eshiswa ngoba amaketanga awo e-molecular ayagoba. I-Silicone iyi-elastomer ene-coefficient ephezulu yokwanda kokushisa. Ngakho-ke, ukuncipha kufanele kucatshangelwe lapho kuklanywa izibunjwa ezenziwe ngerabha ne-silicone. Njengoba ukuncipha kuhluka phakathi kwezinto zokwakha, ubukhulu bungadinga ukulungiswa ngokufanele.

Kusetshenziswa i-primer ekhethekile kanye namasu okwelapha ubuso akhethekile, irabha ye-silicone ingahlangana nezinhlobo ezahlukene ze-substrate, okuhlanganisa izinsimbi ezivamile kanye nepulasitiki.

Isikhathi esinconywayo sokuphila kweshelufu semikhiqizo yerabha ye-silicone siyiminyaka engama-20.

I-silicone ingaphinde isetshenziswe futhi isetshenziswe, kodwa ngenxa yokuthi irabha ye-silicone ihlala isikhathi eside kakhulu, isikhathi sokuphila sayo singaphezu kweminyaka eyi-100, ngokuvamile idinga inkampani ekhethekile yokuvuselela kabusha ukuze isetshenziswe kabusha ngempumelelo. Imikhiqizo yerabha ye-silicone enophawu lokuvuselela kabusha oluphrintiwe ingaphinde isetshenziswe yizimoto zokuvuselela kabusha ezinobungani nemvelo. Ngaphezu kwalokho, i-silicone ikhishwa kumaminerali emvelo futhi ayinazo izinto ezinobuthi. Ayinaphunga futhi ayinabo ubuthi uma ishiswa, ngakho-ke ngaphezu kokuvuselelwa kabusha, ingalahlwa ngqo ngaphandle kokulimaza imvelo.

Irabha ye-silicone ikhethwa ukuze isetshenziswe ekwakhiweni kwayo ngenxa yokumelana kwayo nomlilo okuhle kakhulu kanye nobuthi obubambezelekile. Nakuba i-silicone ivimbela umlilo ngokwemvelo, iphinde ihlukaniswe ngama-grade ahlukene okumelana nomlilo ngokusho kwesitifiketi se-UL.

Yebo, izingxenye ezenziwe ngerabha ye-silicone azinamanzi.

Ukumelana kwe-silicone ekushiseni namakhemikhali ekugcineni kusho ukuthi ngeke isabele ngokudla noma ezinye izinto ezitholakala emigqeni ekhulayo. Kodwa-ke, izinto ezihlangabezana nezindinganiso ze-FDA zibhekwa "njengeziphephile ekudleni."

Irabha ye-silicone idlulisa ukushisa kancane kancane, okubangela ukumelana kwayo nokushisa okuhle kakhulu ngokwemvelo. Kodwa-ke, ngokungeza amafomula amakhemikhali akhethwe ngokucophelela, irabha ye-silicone ingaba umqhubi kagesi omuhle.
