1. Viscosity
Tsananguro yematemu esainzi uye tekinoroji: Humiro hwevhoriyamu hwemvura, pseudo-mvura kana pseudo-yakasimba nyaya inopokana nekuyerera, kureva, kukwesha kwemukati kana kuramba kwemukati kwekuyerera pakati pemamorekuru kana ichiyerera pasi pekuita kwesimba rekunze.Mumamiriro ezvinhu akajairika, viscosity yakaenzana zvakananga nekuoma.
2. Kuoma
Kugona kwechinhu kurwisa zvinhu zvakaoma munzvimbo yacho kunonzi kuomarara.Silicone rabha ine Shore kuomarara siyana kubva gumi kusvika 80, iyo inopa vagadziri rusununguko ruzere rwekusarudza kuomarara kunodiwa kuti vanyatsoita chaiwo mabasa.Yakasiyana-siyana yepakati kuomarara kukosha inogona kuwanikwa nekusanganisa polymer substrates, mafirita uye ekuwedzera muzvikamu zvakasiyana.Saizvozvo, iyo nguva uye tembiricha yekudziya nekurapa inogona zvakare kushandura kuomarara pasina kuparadza humwe hunhu hwemuviri.
3. Kusimba simba
Kusimba kwesimba zvinoreva simba rinodiwa muchikamu chega chega kuti chimedu cherubber material chitsemuke.Iko kusimba kusimba kweiyo thermally vulcanized solid silicone rabha iri pakati pe4.0-12.5MPa.Simba rekusimba refluorosilicone rabha riri pakati pe8.7-12.1MPa.Iko kusimba kwesimba remvura silicone rabha iri mumhando ye3.6-11.0MPa.
Chechina, kubvarura simba
Kupokana kunotadzisa kukwidziridzwa kwekuchekwa kana zvibodzwa kana simba richiiswa kune yakachekwa sampuli.Kunyangwe ikaiswa pasi peyakanyanya kunyanyisa kushushikana mushure mekucheka, iyo thermally vulcanized solid silicone rabha haigone kubvaruka.Iyo yekubvarura simba renji yekupisa-vulcanized solid silicone rabha iri pakati pe9-55 kN/m.Simba rekubvarura re fluorosilicone rabha riri pakati pe17.5-46.4 kN/m.Simba rekubvarura remvura silicone rabha rinobva pa11.5-52 kN/m.
5. Kurebesa
Kazhinji inoreva "Ultimate Break Elongation" kana kuti chikamu chekuwedzera chinoenderana nehurefu hwepakutanga kana sampuli yapwanyika.Thermally vulcanized solid silicone rabha kazhinji ine elongation muhuwandu hwe90 kusvika 1120%.Iyo yakawanda elongation yefluorosilicone rabha iri pakati pe159 ne699%.Iyo yakawanda elongation yemvura silicone rabha iri pakati pe220 ne900%.Nzira dzakasiyana dzekugadzirisa uye sarudzo yehardener inogona kuchinja zvakanyanya kureba kwayo.Iyo elongation yesilicone rabha ine zvakawanda zvekuita nekushisa.
6, nguva yekushanda
Nguva yekushanda inoverengwa kubva panguva iyo colloid inowedzerwa kune vulcanizing agent.Iko chaiko hakuna muganho wakazara pakati peiyi nguva yekuvhiya uye inotevera vulcanization nguva.Iyo colloid yakaita vulcanization reaction kubva panguva iyo vulcanizing agent inowedzerwa.Iyi nguva yekushanda inoreva kuti 30-maminetsi vulcanization maitiro echigadzirwa haakanganisa kunaka kwechigadzirwa chakapedzwa.Naizvozvo, iyo nguva yakawanda yakachengetwa muchirongwa chekushanda kwechigadzirwa, inonyanya kubatsira kune chigadzirwa chakapedzwa.
7, nguva yekuzorora
Dzimwe nzvimbo dzinoti inguva yekurapa.Mune mamwe mazwi, iyo vulcanization reaction yesilica gel yakatopera mushure menguva yakareba kudaro.Izvi zvinopera, izvo zvinoreva kuti chigadzirwa chave chiripo, asi chaizvoizvo kuchine chikamu chiduku chekugadzirisa maitiro chisati chapera.Naizvozvo, zvigadzirwa zvakagadzirwa nesilicone rabha, senge silicone molds, kazhinji zvinotora nguva isati yashandiswa.
Silica gel (Silica gel; Silica) alias: Silica gel chinhu chakanyanya kushanda adsorption, chiri chinhu amorphous.Mushonga wayo wemakemikari ndeye mSiO2 · nH2O;haiite nechero chinhu kunze kwekusimba alkali uye hydrofluoric acid.Hainyungudike mumvura uye chero zvinonyungudutsa, isiri-chepfu, haina kunaka, uye yakagadzikana mumakemikari.Mhando dzakasiyana-siyana dzesilica gel dzinogadzira akasiyana microporous zvimiro nekuda kwemaitiro avo akasiyana ekugadzira.Kuumbwa kwemakemikari uye chimiro chemuviri chesilica gel chinotarisa kuti ine zvimwe zvinhu zvakawanda zvakafanana izvo zvakaoma kutsiva: yakakwira adsorption performance, yakanaka thermal kugadzikana, kugadzikana kwemakemikari zvimiro, uye yakakwirira mechanic simba.Zvinoenderana nehukuru hwehukuru hwayo pore, silica gel yakakamurwa kuita: macroporous silica gel, coarse pore silica gel, B-mhando silica gel, yakanaka pore silica gel, nezvimwe.
Mutengo wezvino wesilicone zvinhu hauna kugadzikana, uchikwira zuva rega rega, zvakaoma kwatiri kuona mutengo.Tinogona chete kugadzirasilicone moldsikozvino.
