Ngaba i-silicone yeyemveliso yeplastiki?
I-silica gel yi-colloidal material eyenziwe nge-silicate, eyona nto ihlanganiswe ne-silica, amanzi kunye ne-silicone monomers.Ijeli ye-silica ineempawu ze-elasticity ephezulu, ukucaca okuphezulu, ukuzinza okuphezulu kunye nokumelana nokushisa okuphezulu, ngoko isetyenziswa ngokubanzi kwiinkalo ezahlukeneyo.Nangona i-silica gel ifana neplastiki kwezinye iipropathi, azikho kwiimveliso zeplastiki ukusuka kwindawo yokujonga ukwakheka kweekhemikhali kunye nenkqubo yokulungiselela.
Okokuqala, kukho ukungafani okucacileyo kwisakhiwo sekhemikhali ye-silicone kunye neplastiki.Iiplastiki ngokuqhelekileyo ziqulunqwe ngamacandelo aphezulu e-molecular, avelisa i-molecule ze-chain chain ngokusebenzisa i-polymerization, eyenza isakhiwo esifanayo esiqhubekayo.Ijeli ye-silica iqulunqwe ikakhulu ngamabhondi e-silico-oxygen, okwenza isakhiwo sothungelwano.Ulwakhiwo olukhethekileyo lwebhondi ye-silico-oksijeni yenza i-silica gel ibe neempawu zezinto eziqinileyo ze-colloidal, ngelixa iiplastiki zihlala ziyizinto ezithambileyo ze-colloidal.
Okwesibini, kukho umahluko ocacileyo phakathi kwejeli ye-silica kunye neplastiki kwinkqubo yokulungiselela.Ukulungiswa kweeplastiki ngokuqhelekileyo kuqhutyelwa ngokunyibilika okutshisayo, ukukhupha, ukubunjwa kwenaliti kunye nezinye iindlela zokulungisa ukwenza iimveliso zeemilo ezahlukeneyo kunye nobukhulu.Ukulungiswa kwejeli ye-silica kuqhutywa ikakhulu ngempendulo yejeli ye-hydrated colloid, efuna ukulawula iimeko zokusabela, umlinganiselo kunye nexabiso le-pH kunye nezinye iiparameters, kwaye emva koko ngokumisa kunye nokubala kunye namanye amanyathelo, ukuze yenze i-silico-. inethiwekhi ye-oksijini bond, kwaye ekugqibeleni ilungiswe kwiimveliso ze-silicone.
Ukongeza, kukho umahluko phakathi kwe-silicone kunye neplastiki kwindalo kunye nokusetyenziswa.Iimpawu eziqhelekileyo zeplastiki ziyi-insulation elungileyo, amandla omatshini kunye nokuzinza kweekhemikhali, njl., Ezisetyenziswa ngokubanzi kubomi bemihla ngemihla, ukuveliswa kwemveliso kunye nemimandla yombane.Ijeli ye-silica inozinzo olulungileyo lwe-thermal, ukuxhathisa ukunxiba kunye nokungangeni kweekhemikhali kwaye isetyenziswa kakhulu ekutyeni, ezonyango, kwi-electronics kunye ne-aviation kunye nezinye iindawo.Izicelo eziqhelekileyo zeemveliso ze-silicone ziquka imilomo yeebhotile ze-silicone, i-silicone bracelets kunye ne-silicone seals.
Isishwankathelo, nangona i-silica gel ifana neplastiki kwezinye iipropathi, kukho ukungafani okucacileyo phakathi kwe-silica gel kunye neplastiki ngokubhekiselele kwisakhiwo samakhemikhali, inkqubo yokulungiselela kunye neendawo zokusebenzisa.I-silica gel yinto ekhethekileyo ye-colloidal kunye neempawu zayo ezizodwa kunye nexabiso lesicelo.Ngoko ke, i-silicone ayikho kwiimveliso zeplastiki.
