Izinkambu Zokufaka Isicelo kanye Nesethulo Esiningiliziwe se-Aqueous Hydrophilic Fumed Silica eneNdawo Ekhethekile Yobuso engu-50 m²/g

1. Izimpawu Eziyisisekelo

- Indlela Yokulungiselela: Ikhiqizwa yi-high-temperature hydrolysis ye-silicon tetrachloride elangabini le-hydrogen-oxygen, yakhe i-amorphous silica ku-nanoscale.

- Indawo Ekhethekile: 50 m²/g (iphansi uma kuqhathaniswa, elinezinhlayiya ezinkulu noma isakhiwo esihlangene).

- Izakhiwo ezingaphezulu: I-Hydrophilic (ecebile ngamaqembu e-hydroxyl phezulu, okulula ukuhlakazeka ezinhlelweni ze-polar).

- Usayizi Wezinhlayiyana: Imvamisa phakathi kwebanga lika-5-50 nm, kodwa ngenxa yendawo ethize ephansi, ezinye zingase zihlangane zibe yizinhlayiya zesibili.

2. Izinkambu Zokusebenza Eziwumgogodla

(1) Izigqoko kanye Noyinki

- Umsebenzi: Ukulawulwa kwe-Rheological, anti-sedimentation, matting.

- Indlela yokwenza: Isakhiwo senethiwekhi sakhiwa ngamabhondi e-hydrogen ukuvimbela ukuduma kwezingulube; indawo ethize ephansi ihlinzeka ngokuqina okuncane, okulungele ukumbozwa kwamanzi okudinga i-viscosity ephansi.

- Ikesi: Isetshenziswa ezingxenyeni zezakhiwo ezisekelwe emanzini, ithuthukisa ukuzinza kwesitoreji futhi igwema ukuqina okweqile okuthinta ukusebenza kokwakha ngesikhathi esifanayo.

(2) Izinamathiselo nama-Sealants

- Umsebenzi: Ukuqina, i-thixotropy, ukuqinisa.

- Inzuzo: Impahla ye-hydrophilic inokuhambisana okuhle nezinhlelo ezisekelwe emanzini, futhi ifanele izinamatheliso ezinobungani bemvelo (njenge-glue emhlophe), ukuvimbela ukuthungwa kwezithako zokugcwalisa nokuthuthukisa ukunemba kokwakhiwa.

(3) Ipulasitiki namaRubber

- Umsebenzi: I-semi-reinforcing filler, usizo lokucubungula.

- Isicelo: Kurabha ye-silicone, ingashintsha ingxenye yemikhiqizo ngendawo ethile ephezulu, yehlise izindleko ngenkathi igcina izakhiwo ezithile zemishini; kumapulasitiki (afana ne-PE), kuthuthukisa amandla okuncibilika futhi kunciphise amaphutha okucubungula.

(4) Izimonyo

- Inhloso: Ukulungiswa kwe-viscosity, ukumuncwa kukawoyela, ukuthuthuka kwesikhumba.

- Isibonelo: Isetshenziswa emikhiqizweni yokuvikela ilanga, ilinganisa ukugcwala kwe-emulsion, igwema into "yokuba mhlophe", futhi ibhebhethekisa uwoyela oweqile ngesikhathi esifanayo, ithuthukisa umuzwa oqabulayo.

(5) Imithi kanye nokudla

- Iqhaza: Glidant, disintegrant, carrier.

- Imininingwane: Njengento ecwebezelayo yamaphilisi (njengamaphilisi kavithamini C), ithuthukisa uketshezi ngesikhathi sokubhebhetheka; indawo ethize ephansi inciphisa i-hygroscopicity futhi yandise ukuzinza kwezidakamizwa.

(6) Izinto zikagesi

- Isicelo: Encapsulation materials, thermal conductive fillers.

- Umsebenzi: Kuzinto zokunamathisela ze-epoxy resin encapsulation, ilungisa indawo yokulinganisa futhi ivimbele ukuchichima kweglue; lapho ugcwalisa i-thermal conductive abicah grease, ibhalansisa ukuqhutshwa kwe-thermal kanye ne-extrudability.

3. Ukuhlaziywa Kwezinzuzo Zokusebenza

- Ukuhlakazeka: Indawo ethize ephansi ngokuqhathaniswa inciphisa amandla ezinhlayiyana, ikwenze kube lula ukuhlakazeka emanzini/izincibilikisi ze-polar nokonga ukusetshenziswa kwamandla.

- Ukusebenza kahle kwezindleko: Kushibhile kunemikhiqizo ye-silica evuthayo enendawo ethile ephezulu, futhi ifanele izimo lapho izimfuneko zokuqinisa zingaqinile khona.

- Ukuvumelana: Ingaphezulu le-hydrophilic lilungele amasistimu asekelwe emanzini, ahambisana nenkambiso yokuvikela imvelo (njengokushintsha izinto ezijiya eziphilayo).

4. Izinyathelo zokuphepha

- Imikhawulo Yokuqinisa: Ayifanele imikhiqizo yerabha enezidingo eziphezulu zemishini (njengamasondo amathayi).

- Isitoreji Esomile: Ngenxa ye-hydrophilicity yayo eqinile, idinga ukuvikelwa kumswakama ukuze igweme i-caking futhi ithinte ukuhlakazeka.

- Okunye Ukukhetha: Uma kudingeka ukujiya okuphezulu (njengakumajeli), imikhiqizo enendawo ethile engaphezu kuka-200 m²/g idinga ukushintshwa.

5. Izibonelo Zemikhiqizo Yezimakethe

- Amamodeli Afanayo: Nakuba indawo ethile ye-silica evuthayo evamile (efana ne-AEROSIL 200) iphakeme kakhulu, imikhiqizo eyenziwe ngokwezifiso noma ehlukanisiwe ingafinyelela ku-50 m²/g (njengemodeli ye-"ZLSIL-A50" ye-Zhonglian Chemical Co., Ltd. nabanye abakhiqizi).

- Ukuguqulwa Kwesicelo: Kuvame ukusetshenziswa emikhakheni lapho ukulungiswa okuhle kwezakhiwo ze-rheological kuyadingeka, njengezinamatheliso ze-elekthronikhi ezisezingeni eliphezulu noma ama-gel-grade-grade.

6. Amathrendi Akusasa

- Ukutshala: Ngokuhambisana nokuthuthukiswa kwezinhlelo ezisekelwe emanzini, kuthatha indawo yezithako ezisekelwe ku-solvent.

- Ukwenziwa komsebenzi: Ukulungiswa kwendawo (okufana nama-polymers wokuxhunyelelwa) kunweba ukusetshenziswa kwakho ezintweni ezihlakaniphile, njengabathwali bezidakamizwa ezizwela izinga lokushisa.

Ngokuhlaziya okungenhla, i-aqueous hydrophilic fumed silica enendawo ethile engu-50 m²/g idlala indima ebalulekile emikhakheni yezimboni eziningi ngenxa yamapharamitha ayo okusebenza okulinganiselayo, ikakhulukazi ezimeni lapho ukusebenza kokucubungula nokulawulwa kwezindleko kugcizelelwa khona.
