1. I-Viscosity
Incazelo yamagama esayensi nezobuchwepheshe: Izici zevolumu yoketshezi, uketshezi-mbumbulu noma uketshezi-mbumbulu oluphikisana nokugeleza, okungukuthi, ukungqubuzana kwangaphakathi noma ukumelana kwangaphakathi kokugeleza phakathi kwama-molecule lapho ageleza ngaphansi kwesenzo samandla angaphandle.Ngaphansi kwezimo ezijwayelekile, i-viscosity ilingana ngokuqondile nobulukhuni.

2. Ubulukhuni
Ikhono lempahla yokumelana nezinto eziqinile ezicindezelwe endaweni yayo kubizwa ngokuthi ubulukhuni.Irabha ye-Silicone inobubanzi bokuqina be-Shore obuyi-10 kuya ku-80, okunikeza abaklami inkululeko egcwele yokukhetha ubulukhuni obudingekayo ukuze bafeze kangcono imisebenzi ethile.Amanani ahlukahlukene okuqina aphakathi angafinyelelwa ngokuxuba ama-polymer substrates, izigcwalisi nezithasiselo ngezilinganiso ezihlukene.Ngokufanayo, isikhathi nezinga lokushisa lokushisa nokuphulukisa kungashintsha futhi ubulukhuni ngaphandle kokucekela phansi ezinye izici zomzimba.

3. Amandla okuqina
Amandla okuqina asho amandla adingekayo kuyunithi ngayinye yobubanzi ukuze kudabuke ucezu lwesampula lento yerabha.Amandla aqinile werabha ye-silicone eqinile eshiswe ngokushisa aphakathi kuka-4.0-12.5MPa.Amandla aqinile werabha ye-fluorosilicone aphakathi kuka-8.7-12.1MPa.Amandla aqinile werabha ye-silicone ewuketshezi ikubanga elingu-3.6-11.0MPa.

Okwesine, amandla ezinyembezi
Ukumelana okuvimbela ukukhuliswa kokusikwa noma amaphuzu lapho kusetshenziswa amandla kusampula esikiwe.Ngisho noma ibekwe ngaphansi kwengcindezi ephezulu kakhulu ye-torsional ngemva kokusikwa, irabha eqinile ye-silicone eshibhile ayikwazi ukudatshulwa.Ibanga lamandla okudabula lerabha eqinile ye-silicone eshisayo liphakathi kuka-9-55 kN/m.Uhlu lwamandla okudabula lwerabha ye-fluorosilicone luphakathi kuka-17.5-46.4 kN/m.Amandla okudabula erabha ewuketshezi ye-silicone asukela ku-11.5-52 kN/m.

5. Ukwelula
Ivamise ukusho “Ultimate Break Elongation” noma ukwenyuka kwephesenti uma kuqhathaniswa nobude bangempela lapho isampula linqamuka.Irabha eqinile ye-silicone eshiswe ngokushisa ivamise ukuba nobude ku-90 kuya ku-1120%.Ukwelulwa okujwayelekile kwerabha ye-fluorosilicone kuphakathi kuka-159 no-699%.Ukwelulwa okujwayelekile kwerabha ye-silicone ewuketshezi kuphakathi kuka-220 no-900%.Izindlela ezihlukene zokucubungula nokukhetha kwe-hardener kungashintsha kakhulu ubude bayo.Ukwelulwa kwerabha ye-silicone kuhlobene kakhulu nezinga lokushisa.

6, isikhathi sokusebenza
Isikhathi sokusebenza sibalwa kusukela ngesikhathi i-colloid yengezwe ku-ejenti elimazayo.Empeleni awukho umkhawulo ophelele phakathi kwalesi sikhathi sokusebenza kanye nesikhathi sokwenza vulcanization.I-colloid ibhekane ne-vulcanization kusukela ngesikhathi i-ejenti elimazayo yengezwa.Lesi sikhathi sokusebenza sisho ukuthi ukusabela kwe-vulcanization kwemizuzu engama-30 komkhiqizo akuphazamisi ikhwalithi yomkhiqizo oqediwe.Ngakho-ke, lapho kugcinwa isikhathi esiningi enqubweni yokusebenza komkhiqizo, kuba nenzuzo kakhulu emkhiqizweni ophelile.

7, isikhathi sokuphumula
Ezinye izindawo zingasho ukuthi yisikhathi sokwelapha.Ngamanye amazwi, ukusabela kwe-vulcanization kwejeli ye-silica kuphelile ngemva kwesikhathi eside kangaka.Lokhu ngokuyisisekelo kuyaphela, okusho ukuthi umkhiqizo usuvele utholakala, kodwa empeleni kusenengxenye encane yokusabela kokwelapha okungakapheli.Ngakho-ke, imikhiqizo eyenziwe ngerabha ye-silicone, njengesikhunta se-silicone, ngokuvamile ithatha isikhathi ngaphambi kokuba isetshenziswe.
Ijeli ye-silica (ijeli ye-silica; i-silica) i-alias: Ijeli ye-silica iyinto esebenza kakhulu ye-adsorption, into e-amorphous.Ifomula yayo yamakhemikhali ithi mSiO2 · nH2O;ayisabeli nanoma iyiphi into ngaphandle kwe-alkali enamandla ne-hydrofluoric acid.Ayincibiliki emanzini nakunoma yiziphi izincibilikisi, ayinabuthi, ayinambitheki, futhi azinzile kumakhemikhali.Izinhlobo ezahlukahlukene zejeli ye-silica zakha izakhiwo ezihlukene ezincane ngenxa yezindlela zazo ezihlukene zokukhiqiza.Ukwakheka kwamakhemikhali kanye nokwakheka komzimba kwejeli ye-silica kunquma ukuthi inezinye izinto eziningi ezifanayo okunzima ukuzishintsha: ukusebenza okuphezulu kwe-adsorption, ukuqina okuhle kokushisa, izici zamakhemikhali ezizinzile, namandla aphezulu emishini.Ngokusho kobukhulu bosayizi we-pore, ijeli ye-silica ihlukaniswe ngokuthi: ijeli ye-silica e-macroporous, ijeli ye-silica eqinile ye-pore, ijeli ye-silica yohlobo lwe-B, ijeli ye-silica epholile, njll.

Intengo yamanje yezinto ze-silicone ayizinzile kakhulu, ikhuphuka nsuku zonke, kunzima ngathi ukunquma intengo.Singenza kuphelaisikhunta se-siliconemanje.
