1. Kwishishanya
Ibisobanuro byamagambo yubumenyi nubuhanga: Ibiranga volumetricike yibintu byamazi, pseudo-fluid cyangwa pseudo-ikomeye yibintu bitemba, ni ukuvuga guterana imbere cyangwa kurwanya imbere yimbere hagati ya molekile iyo itemba ikorwa nimbaraga ziva hanze.Mubihe bisanzwe, viscosity ihwanye neza no gukomera.
2. Gukomera
Ubushobozi bwibikoresho byo kurwanya ibintu bikomye hejuru yacyo byitwa gukomera.Rubber ya silicone ifite inkombe ya Shore iri hagati ya 10 na 80, iha abayishushanya umudendezo wuzuye wo guhitamo ibikenewe kugirango bagere kubikorwa byihariye.Indangagaciro zitandukanye zo hagati zishobora kugerwaho muguhuza polymer substrates, kuzuza ninyongeramusaruro muburyo butandukanye.Mu buryo nk'ubwo, igihe n'ubushyuhe bwo gushyushya no gukiza birashobora kandi guhindura ubukana bitarimbuye ibindi biranga umubiri.
3. Imbaraga zikomeye
Imbaraga zingutu bivuga imbaraga zisabwa muri buri gice cyurwego rwo gutera igice cyibikoresho bya rubber.Imbaraga zingana za silicone ikomeye ya silicone ikomeye iri hagati ya 4.0-12.5MPa.Imbaraga zingana za fluorosilicone reberi iri hagati ya 8.7-12.1MPa.Imbaraga zingana za silicone ya silicone iri murwego rwa 3.6-11.0MPa.
Icya kane, imbaraga zo kurira
Kurwanya bibuza kwaguka gukata cyangwa amanota mugihe imbaraga zashyizwe kumurongo waciwe.Nubwo yashyizwe munsi yumuvuduko ukabije wa torsional nyuma yo gukata, reberi ya silicone ikomeye cyane ntishobora gushwanyagurika.Imbaraga zo kurira zingana na silicone ikomeye ishyushye iri hagati ya 9-55 kN / m.Imbaraga zo kurira za fluorosilicone reberi iri hagati ya 17.5-46.4 kN / m.Imbaraga zo kurira za reberi ya silicone yamazi iri hagati ya 11.5-52 kN / m.
5. Kurambura
Mubisanzwe bivuga "Ultimate Break Elongation" cyangwa ijanisha ryiyongera ugereranije n'uburebure bwambere mugihe icyitegererezo kimenetse.Ubushuhe bukabije bwa silicone reberi muri rusange ifite uburebure buri hagati ya 90 na 1120%.Kurambura muri rusange reberi ya fluorosilicone iri hagati ya 159 na 699%.Kurambura muri rusange ka rubber ya silicone iri hagati ya 220 na 900%.Uburyo butandukanye bwo gutunganya no guhitamo gukomera birashobora guhindura cyane kuramba.Kurambura reberi ya silicone bifite byinshi byo gukora n'ubushyuhe.
6, igihe cyo gukora
Igihe cyo gukora kibarwa uhereye igihe colloid yongewe kumukozi wa volcanizing.Mubyukuri ntamupaka wuzuye uri hagati yiki gikorwa nigihe cyo gukurikira.Colloid yahuye na volcanisation kuva igihe agent yongeyeho.Iki gihe cyo gukora bivuze ko iminota 30 yibirunga yibicuruzwa bitagira ingaruka kumiterere yibicuruzwa byarangiye.Kubwibyo, umwanya munini wabitswe mubikorwa byibicuruzwa, niko bigirira akamaro ibicuruzwa byarangiye.
7, igihe cyo gukiza
Ahantu hamwe bazavuga ko gikiza igihe.Muyandi magambo, reaction ya vulcanisation ya silika gel irarangiye ahanini nyuma yigihe kinini.Ibi ahanini birangira, bivuze ko ibicuruzwa bimaze kuboneka, ariko mubyukuri haracyari agace gato ka reaction yo gukira itararangira.Kubwibyo, ibicuruzwa bikozwe muri reberi ya silicone, nkibishushanyo bya silicone, mubisanzwe bifata igihe mbere yo gukoreshwa.
Silica gel (Silica gel; Silica) alias: Gelika ya Silica nikintu gikora cyane adsorption, nikintu cya amorphous.Imiti yimiti ni mSiO2 · nH2O;ntabwo ikora nibintu byose usibye alkali ikomeye na aside hydrofluoric.Ntishobora gushonga mumazi nigishishwa icyo aricyo cyose, kidafite uburozi, uburyohe, kandi gihamye.Ubwoko butandukanye bwa silika gel bugizwe nuburyo butandukanye bwa microporome bitewe nuburyo butandukanye bwo gukora.Imiterere yimiti nuburyo bugaragara bwa silika gel igena ko ifite ibindi bikoresho byinshi bisa nibigoye kuyisimbuza: imikorere ya adsorption nyinshi, ituze ryiza ryumuriro, imiterere yimiti ihamye, nimbaraga zikomeye.Ukurikije ubunini bwacyo bwa pore, gelika ya silika igabanyijemo: macroporous silica gel, coarse pore silica gel, gel B yo mu bwoko bwa B, silika gel, pore nziza ya silika gel, nibindi.
Igiciro kiriho cyibikoresho bya silicone ntigihungabana cyane, kuzamuka burimunsi, biratugoye kumenya igiciro.Turashobora gukora gusasiliconeubungubu.
