KuMmandla weSilicon ye-Organic, izixhobo zerabha ye-silicon esezantsi zinokwahlulwa zibe zizixhobo eziqinileyo nezilulwelo, kwaye zombini izixhobo ngoku zisetyenziswa ngokubanzi kumashishini amakhulu awohlukeneyo, anje ngeglue yeglasi, amanzi e-organic silicone, kunye nokutywinwa kweemveliso zeRubber ye-silicon. izincedisi zokutywina, njl. Kukho ukufana okuninzi phakathi kweendawo zabo zokufaka izicelo kunye neempawu zezinto eziphathekayo, kunye neenkqubo zabo zokuvelisa zahlukile.Kwintsimi yeemveliso, iindima kunye nemisebenzi yazo iyafana.Yintoni umahluko phakathi kwezinto kunye neemveliso ?

Umahluko omkhulu phakathi kwejeli ye-silica elulwelo kunye nejeli ye-silica eqinileyo yile: enye ilulwelo kwaye enye iqinile;kodwa emva kokucubungula imveliso egqityiweyo, ezi zimbini azikho lula ukuzohlula.Ijeli ye-silica elulwelo ilulwelo kwaye inomanzi.Ijeli ye-silica eqinile iqinile kwaye ayinamanzi.

Iinkalo ezahlukeneyo zokusetyenziswa:
(1) I-silicone yolwelo isetyenziswa ngokubanzi kwiimveliso zabantwana, iimveliso ze-silicone zasekhitshini kunye neemveliso zonyango, inokuqhagamshelana ngqo nokutya kunye nomzimba womntu;

(2) Ijeli ye-silica eqinile isetyenziswa ngokubanzi kwiimfuno zemihla ngemihla, iinxalenye zemizi-mveliso nezinto eziziimoto;

(3) Ukhuseleko lwejeli ye-silica ye-liquid kunye ne-silica gel eqinile: Ijeli ye-silica ye-liquid yinto ebonakalayo ebonakalayo, ekhuselekileyo ephezulu yokutya.Akukho zixhobo ezincedisayo ezifana ne-agent vulcanizing zongezwa ngexesha lokubumba.Izinto zokutywina zenziwe ngokutywinwa.

Ijeli ye-silica eqinile yinto eguquguqukayo.I-Vulcanization iyafuneka ukukhawulezisa ixesha lokunyanga.

Ukubumba:

I-Liquid Silicone (LSR): Igama elipheleleyo liyi-injection yokubumba i-rubber ye-silicone ye-liquid, kunye nesixhobo se-vulcanization ngumatshini wokubumba inaliti.Inkqubo yomshini wokubumba i-injection ilula kakhulu, ukuchaneka kwemveliso kuphezulu, kwaye imveliso iphezulu (i-A / B glue ixutywe imizuzwana embalwa kwiqondo lokushisa elithile).Izinto eziphathekayo zixutywe kwaye zongezwa ngeglue yombala kunye ne-catalyst yokufaka ngokuzenzekelayo kwi-mold cavity ngaphandle kokusebenza ngesandla.Izibonelelo zeMveliso Imveliso ine-fluidity elungileyo, ukolula olomeleleyo kunye nokomelela, kwaye isikhunta sidityaniswe nesitofu sokubumba, ngoko ke imveliso inezibuko leplastiki yokutofa kwaye ngokusisiseko akukho migca yokwahlula komhlaba.

I-Silicone eSolid: Izinto ezikrwada zokubumba ijeli ye-silica ziqinile.Emva kokuba umenzi wemveliso yerabha ye-silicone ixutywe ngumxube, kufuneka idibanise umbala weglue kunye ne-catalyst, kwaye emva koko uyinqumle ibe yisayizi efanelekileyo kwaye uyifake ngesandla kwi-mold cavity ukuze ifake kwaye iphilise.Indlela yokucubungula ngokuzenzekelayo idinga ukusebenza kwencwadana ukuthatha isikhunta kunye nokukhupha izinto eziphathekayo.Ngenxa yokuba i-material iqinile, i-fluidity kunye nokolula ukomelela kungaphantsi kancinci kunolwelo.Imveliso ayinayo i-port ye-injection, kwaye imveliso egqityiweyo egqityiweyo iya kuba nemigca ephezulu kunye nesezantsi.

Yintoni Umahluko phakathi kweSilicone eLiquid kunye neZizinto zeSilicone eziSolid?
Ijeli ye-silica eqinile yenziwa kwimizi-mveliso yeglasi yamanzi (i-sodium silicate) njengento ekrwada, i-hydrolyzed kwi-acid medium ukwenza ijeli, emva koko yenziwe ibe yijeli ye-silica ngokuguga, ukuhlamba, ukomisa, njl., kuxhomekeke kumxholo wamanzi. ukuguquguquka okanye okumhlophe okuqinileyo.Iimveliso ezikwiimarike zineejeli ze-silica ezingqukuva, ezingqukuva, kunye ne-microspherical, ezidla ngokusetyenziswa njengezinto ezibangela ukuba vulcanization kwimisebenzi yebhedi enolwelo.

Mbini.Xa isetyenziswe njenge-catalyst carrier, i-silica gel ivame ukucwiliswa kwisisombululo esinamacandelo asebenzayo, ukwenzela ukuba isisombululo sifakwe kwi-pores ye-silica gel, kwaye izinto ezisebenzayo zisasazwa phezu kwe-silica.I-Gelation ngokumisa, ukusebenza, njl. Ubume be-pore ye-silica gel inempembelelo ebalulekileyo kwiipropati ze-catalyst exhaswayo elungiselelwe, njengomthamo we-pore kunye nokusabalalisa ubungakanani be-silica gel.Ngokuqhelekileyo, ijeli ye-silica ene-avareji ye-pore diameter engaphantsi kwe-15 ukuya kwi-20 ibizwa ngokuba yijeli ye-silica ecocekileyo;kunye ne-avareji ye pore diameter engaphezulu kwama-40 ukuya kuma-50 angstrom ibizwa ngokuba yijeli yesilica erhabaxa.

Ukuqaliswa kwenkqubo ye-silicone yolwelo

Ijeli ye-silica elulwelo isetyenziswa kwishishini ukuze ikhuphe amanzi e-sodium kwi-silica sol ngokutshintshiselana kwe-ion.Lulwelo olumhlophe olulubisi oluguquguqukayo olunozinzo oluphezulu.Ijeli ye-silica eqinileyo iba yinto eqinileyo enemingxuma emva kokumiswa.Ngokomzekelo, ekulungiseleleni (i-phosphorus-molybdenum-niobium-oxygen) / i-silica catalyst yokulungiselela i-acrylonitrile nge-oxidation ye-oxidative ye-propylene, isisombululo esiqulethe izinto ezisebenzayo zixutywe ne-silica sol, kunye ne-microspheres zilungiswa ngokutshiza i-catalyst.
