1. Ukuxinana
Inkcazo yamagama esayensi netekhnoloji: Iimpawu zevolumu zezinto ezilulwelo, ezilulwelo oluyi-pseudo okanye ezilulwelo oluyi-pseudo-solid xa zithelekiswa nokuhamba kwamanzi, oko kukuthi, ukungqubana kwangaphakathi okanye ukumelana kwangaphakathi kokuhamba kwamanzi phakathi kwee-molecule xa zihamba phantsi kwesenzo samandla angaphandle. Kwiimeko eziqhelekileyo, i-viscosity ihambelana ngqo nobunzima.

2. Ukuqina
Amandla ezinto ezisetyenziswayo ukumelana nezinto eziqinileyo ezicinezelwe kumphezulu wazo abizwa ngokuba bubunzima. Irabha yesilicone inoluhlu lobunzima beShore oluqala kwi-10 ukuya kwi-80, nto leyo enika abayili inkululeko epheleleyo yokukhetha ubunzima obufunekayo ukuze bafezekise imisebenzi ethile. Amaxabiso ahlukeneyo obulukhuni obuphakathi anokufezekiswa ngokuxuba ii-substrates zepolymer, izizalisi kunye nezongezo ngobuninzi obahlukeneyo. Ngokufanayo, ixesha kunye nobushushu bokufudumeza kunye nokunyanga kunokutshintsha ubulukhuni ngaphandle kokutshabalalisa ezinye iimpawu zomzimba.

3. Amandla okuxinana
Amandla okutsalwa abhekisa kumandla afunekayo kwiyunithi nganye yoluhlu ukuze kukrazuke isampulu yezinto zerabha. Amandla okutsalwa kwerabha ye-silicone eqinileyo evulcanized thermally aphakathi kwe-4.0-12.5MPa. Amandla okutsalwa kwerabha ye-fluorosilicone aphakathi kwe-8.7-12.1MPa. Amandla okutsalwa kwerabha ye-silicone engamanzi aphakathi kwe-3.6-11.0MPa.

Isine, amandla okukrazula
Ukumelana okuthintela ukwanda kwesinqumlo okanye amanqaku xa kusetyenziswa amandla kwisampulu esinqumliweyo. Nokuba ibekwe phantsi koxinzelelo oluphezulu kakhulu emva kokusikwa, irabha ye-silicone eqinileyo evulcanized thermally ayinakukrazulwa. Uluhlu lwamandla okukrazulwa kwerabha ye-silicone eqinileyo evulcanized hot-vulcanized luphakathi kwe-9-55 kN/m. Uluhlu lwamandla okukrazulwa kwerabha ye-fluorosilicone luphakathi kwe-17.5-46.4 kN/m. Amandla okukrazulwa kwerabha ye-silicone engamanzi aqala kwi-11.5-52 kN/m.

5. Ukwandiswa
Ngokwesiqhelo ibhekisa kwi-"Ultimate Break Elongation" okanye ukwanda kwepesenti ngokumalunga nobude bokuqala xa isampuli iqhekeka. Irabha ye-silicone eqinileyo evulcanized thermally idla ngokuba nobude obuphakathi kwe-90 ukuya kwi-1120%. Ukwandiswa ngokubanzi kwerabha ye-fluorosilicone kuphakathi kwe-159 kunye ne-699%. Ukwandiswa ngokubanzi kwerabha ye-silicone engamanzi kuphakathi kwe-220 kunye ne-900%. Iindlela ezahlukeneyo zokucubungula kunye nokukhetha i-hardener kunokutshintsha kakhulu ukwandiswa kwayo. Ukwandiswa kwerabha ye-silicone kunento yokwenza kakhulu nobushushu.

6, ixesha lokusebenza
Ixesha lokusebenza libalwa ukususela ngexesha i-colloid yongezwa kwi-agent ye-vulcanizing. Akukho mda upheleleyo phakathi kweli xesha lokusebenza kunye nexesha elilandelayo le-vulcanization. I-colloid iye yafumana i-vulcanization reaction ukususela ngexesha i-agent ye-vulcanizing yongezwa ngalo. Eli xesha lokusebenza lithetha ukuba i-30-minute vulcanization reaction yemveliso ayichaphazeli umgangatho wemveliso egqityiweyo. Ke ngoko, okukhona ixesha ligcinwa kwinkqubo yokusebenza kwemveliso, kokukhona inenzuzo enkulu kwimveliso egqityiweyo.

7, ixesha lokuphilisa
Ezinye iindawo ziya kuthi lixesha lokuphiliswa. Ngamanye amazwi, i-vulcanization reaction ye-silica gel iphela emva kwexesha elide kangaka. Oku kuyaphela, oko kuthetha ukuba imveliso sele ikhona, kodwa eneneni kusekho inxalenye encinci ye-curing reaction engekapheli. Ke ngoko, iimveliso ezenziwe ngerabha ye-silicone, ezifana nee-silicone molds, zihlala zithatha ixesha ngaphambi kokuba zisetyenziswe.
Ijeli yeSilica (ijeli yeSilica; iSilica) igama elidala: Ijeli yeSilica yinto esebenza kakhulu ekufakweni kwayo, eyinto engenasimo. Ifomula yayo yekhemikhali yi-mSiO2·nH2O; ayisebenzi nayo nayiphi na into ngaphandle kwe-alkali enamandla kunye ne-hydrofluoric acid. Ayinyibiliki emanzini nakweyiphi na i-solvents, ayinatyhefu, ayinancasa, kwaye izinzile ngokweekhemikhali. Iintlobo ezahlukeneyo zejeli ye-silica zakha izakhiwo ezahlukeneyo ze-microporous ngenxa yeendlela zazo ezahlukeneyo zokwenza. Ulwakhiwo lweekhemikhali kunye nolwakhiwo lomzimba lwejeli ye-silica lugqiba ukuba inezinye izinto ezininzi ezifanayo ezinzima ukuzitshintsha: ukusebenza okuphezulu kokufakweni kwayo, uzinzo oluhle lobushushu, iipropati zekhemikhali ezizinzileyo, kunye namandla aphezulu oomatshini. Ngokobungakanani bobukhulu be-pore yayo, ijeli ye-silica yahlulwe yaba: ijeli ye-silica emacroporous, ijeli ye-silica emacroporous, ijeli ye-silica emacroporous, ijeli ye-silica e-coarse pore, ijeli ye-silica yohlobo lwe-B, ijeli ye-silica emacroporous, njl.

Ixabiso langoku lezinto ze-silicone alizinzanga kakhulu, linyuka yonke imihla, kunzima kuthi ukumisela ixabiso. Singenza kuphelaii-silicone moldsngoku.
