I-silicone yodlula njani ngesikhumba sokwenziwa kwesintu?
2023-11-23
I-permeability yesikhumba sokwenziwa kwesintu ihlala ihlwempuzekile, ngelixa ukunyanzeliswa kwesikhumba se-silicone kungcono. Ngenxa yomsantsa omkhulu phakathi kweemolekyuli zayo, inceda ngakumbi ekungeneni komphunga wamanzi. Xa kuthelekiswa nesikhumba sokwenziwa kwemveli, isikhumba se-silicone sinokungena komoya okungcono. Ngokubhekiselele ekuxhathiseni ukunxiba, isikhumba se-silicon ye-organic nayo yodlula ngokupheleleyo ufele lwemveli olwenziweyo. I-organic silicon yesikhumba inokumelana nokunxiba kakuhle. Ngaphantsi kovavanyo lokumelana nokunxiba, isantya esijikelezayo si-60 revolutions phantsi komthwalo we-1000g, kwaye isantya esijikelezayo singaphezulu kwe-2000 revolutions ngomzuzu. Akukho tshintsho lucacileyo. I-coefficient iphezulu kwibakala 4. Kubomi bemihla ngemihla, inokuhlangabezana neemfuno zeemeko ezahlukeneyo zesicelo.
Ngokubhekiselele kwiipropathi zesikhumba, ukuxhathisa ukufuma okunokuthi abantu abambalwa banikele ingqalelo ngokwenene kubaluleke kakhulu. Ngokomzekelo, kwimozulu emanzi emzantsi, isikhumba sokwenziwa kwendabuko sinokuba nemvakalelo emanzi phezu komhlaba, embi kakhulu. Ngaphantsi kovavanyo lobungqina bomswakama, xa ubushushu bungama-40 ° C, umswakama ngu-92%, kwaye imveliso ayinalo utshintsho olungaqhelekanga. Ukusebenza kobungqina bokufuma kugqwesileyo, okunokuthi kuthintele ufele ukuba lonakaliswe yimozulu emanzi. Esi sakhiwo samakhemikhali esiyingqayizivele se-silicone.
Ke kuthekani ngobomi besikhumba se-silicone? Enye yeempawu zesikhumba se-silicone kukuba inokumelana nokuguga okugqwesileyo, ukuxhathisa okunamandla kwe-hydrolysis, ukuxhathisa kwemozulu kunye nokumelana ne-UV, ezingcono kunesikhumba sokwenziwa kwendabuko, ngoko ubomi bayo buya kuba bude.
Ukuzuza ngokusemthethweni kwiimpawu ezingenakuthelekiswa nanto ze-silicon, okwenza ukuba igcine uzinzo kunye nokusebenza okugqwesileyo kwiindawo ezininzi ezinzima, kunye nenkqubo yesikhumba ye-silicone ekhulayo, eninzi ixesha elide kumswakama, imboni ye-corrosion, ibe yimimandla ephambili yesicelo sesikhumba se-silicone, njenge ifenitshala kunye nokuhombisa kwiiyachts, ifenitshala yangaphandle, izihlalo zeemoto, izixhobo zonyango njalo njalo. Ukongeza kwi-asidi kunye nokumelana ne-alkali, i-silicone yesikhumba nayo ine-anti-wrinkle kunye ne-anti-ultraviolet iipropati, nokuba ukukhanya kwexesha elide kwilanga langaphandle, akusayi kuba nayiphi na impembelelo, ngoko ke, izihlalo ezininzi zezemidlalo ngoku zisebenzisa isikhumba se-silicone ukuvelisa. .
