Ku-Field Of Organic Silicon, izinto zenjoloba ye-silicon engezansi zingahlukaniswa zibe izinto eziqinile neziwuketshezi, futhi zombili izinto zokwakha okwamanje zisetshenziswa kabanzi ezimbonini ezinkulu ezihlukahlukene, ezifana ne-potting glass glue, organic silicone water, kanye nokuvala imikhiqizo ye-silicon Rubber, electronic. izesekeli zokuvala uphawu, njll. Kukhona ukufana okuningi phakathi kwezinkambu zabo zokufaka isicelo kanye nezakhiwo ezibonakalayo, futhi izinqubo zabo zokukhiqiza zihlukile.Emkhakheni wemikhiqizo, izindima nemisebenzi yabo iyafana.Uyini umehluko phakathi kwezinto zokwakha kanye nemikhiqizo?

Umehluko omkhulu phakathi kwejeli ye-silica ewuketshezi kanye nejeli ye-silica eqinile: enye iwuketshezi kanti enye iqinile;kodwa ngemva kokucubungula umkhiqizo osuphelile, lezi ezimbili akulula kakhulu ukuzihlukanisa.Ijeli ye-silica ewuketshezi iwuketshezi futhi inoketshezi.Ijeli ye-silica eqinile iqinile futhi ayinamanzi.

Izinkambu ezahlukene zokusetshenziswa:
(1) I-silicone ewuketshezi ngokuvamile isetshenziswa emikhiqizweni yezingane, emikhiqizweni yasekhishini ye-silicone kanye nemikhiqizo yezokwelapha, ingathintana ngqo nokudla kanye nomzimba womuntu;

(2) Ijeli yesilika eqinile ngokuvamile isetshenziselwa izidingo zansuku zonke, izingxenye ezixubile zezimboni kanye nezingxenye zezimoto;

(3) Ukuphepha kwejeli ye-silica ewuketshezi kanye nejeli ye-silica eqinile: Ijeli ye-silica ewuketshezi iyinto esobala kakhulu, ephephile kakhulu yezinga lokudla.Azikho izinto ezisizayo ezifana ne-ejenti ye-vulcanizing ezingeziwe ngesikhathi sokubumba.Impahla yokuvala yakhiwa ngokuvala.

Ijeli ye-silica eqinile iyinto ekhanyayo.I-Vulcanization iyadingeka ukusheshisa isikhathi sokwelapha.

Ukubumba:

I-Liquid Silicone (LSR): Igama eligcwele irabha ye-silicone ewuketshezi yokufaka umjovo, kanti okokusebenza kwe-vulcanization umshini wokubumba umjovo.Inqubo yomshini wokubumba umjovo ilula kakhulu, ukunemba komkhiqizo kuphezulu, futhi okukhiphayo kuphezulu (i-A/B glue ixutshwe imizuzwana embalwa ekushiseni okuthile).Izinto ezisetshenziswayo zixutshwe futhi zengezwe ngeglue enemibala kanye ne-catalyst ukuze zijove ngokuzenzakalelayo emgodini wesikhunta ngaphandle kokusebenza ngesandla.Izinzuzo zomkhiqizo Umkhiqizo une-fluidity enhle, ukunwebeka okuqinile nokuqina, futhi isikhunta sihlanganiswe ukubumba komjovo, ngakho umkhiqizo unembobo yomjovo wepulasitiki futhi ngokuyisisekelo ayikho imigqa yokuhlukanisa indawo.

I-Silicone Eqinile: Impahla eluhlaza yokubumba ijeli ye-silica iqinile.Ngemuva kokuthi umkhiqizi womkhiqizo werabha ye-silicone exutshwe yi-mixer, udinga ukwengeza iglue yombala kanye ne-catalyst, bese uyisika ibe usayizi ofanele futhi uyifake ngesandla emgodini wesikhunta ukuze wakhe futhi uphulukise.Indlela yokucubungula okuzenzakalelayo idinga ukusebenza ngesandla ukuze kuthathwe isikhunta futhi kukhishwe impahla.Ngenxa yokuthi i-material iqinile, i-fluidity kanye nokuqina kokuqina kungaphansi kancane kunoketshezi.Umkhiqizo awunayo imbobo yomjovo, futhi umkhiqizo oqediwe ocutshunguliwe uzoba nemigqa ehlukanisayo ephezulu naphansi .

Uyini Umehluko Phakathi Kwezinto Ze-Silicone Ewuketshezi Nezinto Eziqinile Ze-Silicone?
Ijeli ye-silica eqinile yenziwa ngokwezimboni ngengilazi yamanzi (i-sodium silicate) njengento eluhlaza, i-hydrolyzed endaweni ye-asidi ukuze yakhe ijeli, bese yenziwa ijeli ye-silica ngokuguga, ukuwashwa, ukomiswa, njll., kuya ngokuqukethwe kwamanzi, okucwebezelayo noma okumhlophe okuqinile.Imikhiqizo emakethe inamajeli e-silica ayi-granular, ayindilinga, kanye ne-microspherical, avame ukusetshenziswa njengama-catalysts e-vulcanization ekusebenzeni kombhede omanzi.

ezimbili.Uma isetshenziswa njengesithwali se-catalyst, ijeli ye-silica ivame ukucwiliswa esixazululweni esiqukethe izingxenye ezisebenzayo, ukuze isisombululo singene kuma-pores we-silica gel, futhi izingxenye ezisebenzayo zisatshalaliswa ebusweni be-silica.I-Gelation ngokusebenzisa ukomiswa, ukwenza kusebenze, njll. Isakhiwo se-pore sejeli ye-silica sinethonya elibalulekile ezimpahleni ze-catalyst esekelwe elungiselelwe, njengevolumu yembotshana kanye nokusabalalisa usayizi we-pore wejeli ye-silica.Ngokuvamile, ijeli ye-silica enobubanzi obuyimbotshana obuphakathi obungaphansi kuka-15 kuya ku-20 ibizwa ngokuthi ijeli ye-silica ye-pore;futhi i-avareji yembotshana ububanzi engaphezu kuka-40 kuya ku-50 angstrom ibizwa ngokuthi ijeli ye-silica ye-pore.

Isingeniso senqubo ye-silicone ewuketshezi

Ijeli ye-silica ewuketshezi isetshenziswa embonini ukukhipha amanzi e-sodium abe yi-silica sol ngokushintshaniswa kwe-ion.Iwuketshezi olumhlophe oluyi-milky olushintshashintshayo olunokuqina okuphezulu.Ijeli ye-silica eqinile iba isiqinile esinezimbotshana ngemva kokoma.Isibonelo, ekulungiseleleni i-(phosphorus-molybdenum-niobium-oxygen)/i-silica catalyst yokulungiselela i-acrylonitrile nge-oxidative oxidation ye-propylene, isisombululo esiqukethe izingxenye ezisebenzayo sixutshwe ne-silica sol, futhi ama-microspheres alungiswa ngokufafaza i-catalyst.
