Iimpawu zezinto ze-silica gel, iteknoloji yokucubungula kunye nokusetyenziswa

Izinto ze-silica gel zineempawu zokusebenza okuphezulu kwe-adsorption, ukuzinza okuhle kwe-thermal, ukuzinza kweekhemikhali, amandla aphezulu omatshini kunye nokunye, kwaye isetyenziswa ngokubanzi kuyilo lwemveliso. Kwaye izinto eziphathekayo zatshintshwa zibe yijeli ye-silica ekhethekileyo ukuze ihambelane neemfuno zokusebenza kweemveliso ezahlukeneyo, ezifana ne-luminous, ion negative, i-discoloration kunye nezinye iimpawu.

Intshayelelo ye-silica gel

Ijeli ye-silica luhlobo lwezixhobo ze-adsorption ezisebenzayo kakhulu, ze-amorphous substance, equkethe i-polysiloxane, ioli ye-silicone, i-silica emnyama (i-silica), i-agent edibeneyo kunye ne-filler, njl., inxalenye ephambili yi-silica. I-insoluble emanzini kunye nayiphi na i-solvent, i-non-toxic kunye ne-tasteless, i-chemicals stable, ngaphandle kwe-alkali eqinile, i-hydrofluoric acid ayifuni nayiphi na into. Iindidi ezahlukeneyo zejeli ye-silica zenza izakhiwo ezahlukeneyo ze-micropore ngenxa yeendlela zabo ezahlukeneyo zokuvelisa. Ukwakhiwa kweekhemikhali kunye nesakhiwo somzimba we-silica gel sinquma ukuba sineempawu zezinye izinto ezininzi ezifanayo okunzima ukuzitshintsha: ukusebenza okuphezulu kwe-adsorption, ukuzinza okuhle kwe-thermal, iipropati ezizinzileyo zeekhemikhali, kunye namandla aphezulu omatshini.

Ukuhlelwa kwejeli ye-silica

I-Silicone inokuhlelwa ngokweempawu ezahlukeneyo:

Ngokutsho kokubunjwa kunokwahlulwa ibe: icandelo elinye kunye necandelo ezimbini ze-silica gel.
Ngokutsho vulcanization lobushushu inokwahlulwa ibe: vulcanization lobushushu eliphezulu kunye nobushushu begumbi vulcanization abicah.
Ngokwemilo yemveliso inokwahlulwa ibe: ijeli ye-silica engamanzi kunye neqinile.
Ngokutsho reaction vulcanization zinokwahlulwa ibe: uhlobo yokusabela condensation, platinum ukongeza uhlobo reaction kunye nodidi peroxide ukuhlanganiswa.
Ngokwesakhiwo sekhonkco esiphambili sinokuhlulwa sibe: i-silica gel ecocekileyo kunye ne-silica gel eguquliweyo.
Ngokweempawu zemveliso zinokwahlulwa zibe: uhlobo oluphezulu nolusezantsi lokumelana nobushushu, uhlobo lwe-anti-static, i-oyile kunye nokumelana ne-solvent, uhlobo lwe-conductive, uhlobo lwesiponji sogwebu, uhlobo lokumelana nokukrazula amandla aphezulu, uhlobo lokhuselo lomlilo olunelangatye, uhlobo oluphantsi loxinzelelo lwe-deformation. .
