1. Ukujiya
Incazelo yamagama esayensi nobuchwepheshe: Izici zevolumu zezinto eziwuketshezi, eziwuketshezi oluyi-pseudo noma eziwuketshezi oluyi-pseudo-solid ngokumelene nokugeleza, okungukuthi, ukungqubuzana kwangaphakathi noma ukumelana kwangaphakathi kokugeleza phakathi kwama-molecule lapho kugeleza ngaphansi kwesenzo samandla angaphandle. Ngaphansi kwezimo ezivamile, i-viscosity ihambisana ngqo nobunzima.

2. Ubulukhuni
Ikhono lento yokumelana nezinto eziqinile ezicindezelwe ebusweni bayo libizwa ngokuthi ubulukhuni. Irabha ye-silicone inobubanzi bobulukhuni be-Shore obuyi-10 kuya ku-80, okunikeza abaklami inkululeko ephelele yokukhetha ubulukhuni obudingekayo ukuze bafeze imisebenzi ethile kangcono. Amanani ahlukahlukene obulukhuni obuphakathi angatholakala ngokuxuba ama-polymer substrates, ama-filler kanye nezithasiselo ngezilinganiso ezahlukene. Ngokufanayo, isikhathi kanye nezinga lokushisa lokushisa nokulungisa nakho kungashintsha ubulukhuni ngaphandle kokubhubhisa ezinye izici zomzimba.

3. Amandla okudonsa
Amandla okudonseka abhekisela emandleni adingekayo kuyunithi ngayinye yobubanzi ukuze kudabuke ucezu lwezinto zerabha. Amandla okudonseka kwerabha ye-silicone eqinile evulcanized thermally aphakathi kuka-4.0-12.5MPa. Amandla okudonseka kwerabha ye-fluorosilicone aphakathi kuka-8.7-12.1MPa. Amandla okudonseka kwerabha ye-silicone ewuketshezi aphakathi kuka-3.6-11.0MPa.

Okwesine, amandla okudabuka
Ukumelana okuvimbela ukwandiswa kokusikwa noma i-score lapho kusetshenziswa amandla kusampula yokusikwa. Ngisho noma ibekwe ngaphansi kokucindezeleka okuphezulu kakhulu kokugoba ngemva kokusikwa, irabha ye-silicone eqinile evulcanized thermally ayikwazi ukudabuka. Ububanzi bamandla okudabuka kwerabha ye-silicone eqinile evulcanized hot-vulcanized buphakathi kuka-9-55 kN/m. Ububanzi bamandla okudabuka kwerabha ye-fluorosilicone buphakathi kuka-17.5-46.4 kN/m. Amandla okudabuka kwerabha ye-silicone ewuketshezi asukela ku-11.5-52 kN/m.

5. Ukwelula
Ngokuvamile kubhekisela ku-“Ultimate Break Elongation” noma ukwanda kwamaphesenti uma kuqhathaniswa nobude bokuqala lapho isampula iphuka. Irabha ye-silicone eqinile evulcanized Thermally ngokuvamile inobude obuphakathi kuka-90 no-1120%. Ukwandiswa okujwayelekile kwerabha ye-fluorosilicone kuphakathi kuka-159 no-699%. Ukwandiswa okujwayelekile kwerabha ye-silicone ewuketshezi kuphakathi kuka-220 no-900%. Izindlela ezahlukene zokucubungula kanye nokukhetha i-hardener kungashintsha kakhulu ukwandiswa kwayo. Ukwandiswa kwerabha ye-silicone kuhlobene kakhulu nokushisa.

6, isikhathi sokusebenza
Isikhathi sokusebenza sibalwa kusukela ngesikhathi i-colloid ingezwa ku-ejenti ye-vulcanizing. Empeleni akukho mkhawulo ophelele phakathi kwalesi sikhathi sokusebenza nesikhathi esilandelayo se-vulcanization. I-colloid iye yabhekana nokusabela kwe-vulcanization kusukela ngesikhathi i-ejenti ye-vulcanizing ingezwa ngaso. Lesi sikhathi sokusebenza sisho ukuthi ukusabela kwe-vulcanization kwemizuzu engama-30 komkhiqizo akuthinti ikhwalithi yomkhiqizo oqediwe. Ngakho-ke, lapho isikhathi esiningi silondolozwa enkambisweni yokusebenza komkhiqizo, kulapho kuzuzisa khona umkhiqizo oqediwe.

7, isikhathi sokupholisa
Ezinye izindawo zizothi sekuyisikhathi sokuphola. Ngamanye amazwi, ukusabela kwe-silica gel okubangela ukubola kuphelile ngemva kwesikhathi eside kangaka. Lokhu kuphelela, okusho ukuthi umkhiqizo usuvele utholakala, kodwa empeleni kusenengxenye encane yokusabela kokuphola engakapheli. Ngakho-ke, imikhiqizo eyenziwe ngerabha ye-silicone, njenge-silicone molds, imvamisa ithatha isikhathi ngaphambi kokuba isetshenziswe.
Ijeli ye-Silica (ijeli ye-Silica; i-Silica) igama elivamile: Ijeli ye-Silica iyinto esebenza kakhulu yokumunca, okuyi-amorphous. Ifomula yayo yamakhemikhali yi-mSiO2·nH2O; ayisebenzi nanoma iyiphi into ngaphandle kwe-alkali enamandla ne-hydrofluoric acid. Ayincibiliki emanzini nanoma yiziphi izinyibilikisi, ayinabo ubuthi, ayinambitheki, futhi izinzile ngamakhemikhali. Izinhlobo ezahlukene zejeli ye-silica zakha izakhiwo ezahlukene ze-microporous ngenxa yezindlela zazo ezahlukene zokukhiqiza. Ukwakheka kwamakhemikhali kanye nesakhiwo somzimba sejeli ye-silica kunquma ukuthi inezinye izinto eziningi ezifanayo okunzima ukuzishintsha: ukusebenza okuphezulu kokumunca, ukuzinza okuhle kokushisa, izakhiwo zamakhemikhali ezizinzile, kanye namandla aphezulu omshini. Ngokusho kosayizi wosayizi wayo we-pore, ijeli ye-silica ihlukaniswe phakathi: ijeli ye-silica emacroporous, ijeli ye-silica emacoarse pore, ijeli ye-silica yohlobo lwe-B, ijeli ye-silica emacoarse pore, njll.

Intengo yamanje yezinto ze-silicone ayizinzile, ikhuphuka nsuku zonke, kunzima kithi ukunquma intengo. Singenza kuphelaizikhunta ze-siliconemanje.
