Abavelisi beemveliso ze-silica gel bavelisa iimveliso ezahlukeneyo zejeli ye-silica, ngokweemfuno zabathengi kunye nemisebenzi eyahlukeneyo yejeli ye-silica, banokuvelisa iimveliso ezahlukeneyo ze-silica ukuze basebenzise abathengi.Ngoko ke zeziphi iingxaki abavelisi be-silicone kufuneka banakekele kwimveliso?
1. Ukuveliswa kweemveliso ze-silicon kangangoko kunokwenzeka ukuphepha naluphi na uhlobo lwe-asidi eyomeleleyo kunye neekhemikhali zealkali
Irabha ye-Silicone luhlobo lwesiseko se-adsorption esisebenza kakhulu, esinganyibilikiyo emanzini kunye naso nasiphi na isinyibilikisi, esingenatyhefu kunye nencasa, iipropathi zekhemikhali ezizinzileyo.Ngaphandle kwe-alkali eyomeleleyo, i-asidi eyomeleleyo, ayifuni nantoni na.Utshintsho lweMichiza luya kwenzeka phantsi kwe-asidi eqinile kunye nesiseko, ngoko zama ukuphepha olu hlobo lwe-asidi eqinile kunye neekhemikhali ezisisiseko kwinkqubo yokusetyenziswa.Iindidi ezahlukeneyo zejeli ye-silica zenza izakhiwo ezahlukeneyo ze-micropore ngenxa yeendlela zabo ezahlukeneyo zokuvelisa.
2. Iimveliso ze-silica zejeli kunzima ukubuyisela ukubunjwa kweekhemikhali kunye nesakhiwo somzimba we-silica gel, egqiba ukuba ine-perperty ekhethekileyo ukuba ezinye izinto ezininzi ezifanayo kunzima ukubuyisela iimpawu zayo: umsebenzi ophezulu we-adsorption, uzinzo oluhle lwe-thermal, iikhemikhali ezizinzileyo. iipropati, amandla aphezulu omatshini, njl. Ngokobukhulu bayo be-silicone, i-silicone yahlulwe yaba: ijeli ye-silica ye-pore enkulu, i-coarse pore silica gel, i-B uhlobo lwe-silica gel, i-gel pore silica gel.
3. Ukuvelisa iimveliso ze-silica gel ukwenzela ukuba yedwa kunye nokukhusela.Olona phawu lucacileyo lwejeli ye-silica yi-adsorption, eyona nto iluthuli olutsalwa ngumoya okanye uthuli oluthile kwinkangeleko, lubangela ukubonakala kumdaka kakhulu.Ngenxa yolu phawu, kwinkqubo yokuvelisa, umzi-mveliso kufuneka uphumeze ukukhuselwa kwe-silicone yodwa ukusuka kwinqanaba lokuxuba i-rubber, ukusetyenziswa kwephepha lerabha elicacileyo ukuze livule umphezulu walo.Ngale ndlela, nokuba izinto zisekho kwinkqubo yokulayisha ngothuli okanye umlotha, aziyi kuqhagamshelana nokubonakala kwe-silica gel izinto eziluhlaza, ukwenzela ukuba kuveliswe iimveliso ze-silica gel ngokucoceka ngakumbi.
