Ukwengeza irabha ye-silicone ewuketshezi

Irabha ye-silicone ye-addition liquid iyinhlangano ye-silicone engenabuthi futhi engenaphunga enokumelana nokuswakama okuhle kakhulu, ukumelana nokubanda, ukumelana nokushisa, ukwahlukanisa, ukumelana nemisebe kanye nokumelana nesimo sezulu.

Ingahlanganiswa nezinto ezihlukahlukene, njenge-PC, i-PA, i-TPU ne-ABS.Ukusetshenziswa kwe-ejenti yokunamathisela yerabha yerabha ye-silicone yohlobo lokwengeza kungathuthukisa ukusebenza kahle kokukhiqiza okubophayo kwerabha ye-silicone nalezi zinto futhi kuzenze zihlanganiswe.Imikhiqizo ebunjwe ngamakhemikhali iphephile, ayinabo ubuthi futhi ayinazincibilikisi.

Irabha ye-abicah ewuketshezi yokwengeza isetshenziswa kakhulu ku-elekthronikhi nakugesi, ukwakhiwa, izimoto, imishini, ezokwelashwa neminye imikhakha.

Izici ze-silicone ze-LSR

I-silicone ye-1.LSR iyisigaba samaqembu amabili we-AB, axutshwe futhi anyakaziswa ngokulinganayo u-A no-B ngesilinganiso sesisindo esingu-1: 1, Isikhathi sokusebenza siyimizuzu engu-~30, isikhathi sokuphulukisa singamahora angu-2, kanye nokususa isikhunta ngo-8. amahora.

2. Ukuqina kuhlukaniswe: abicah super soft -below 0A, 0A-60A isikhunta abicah,
inezinzuzo zombala omude nokunwebeka okukhulu

3. Ngaphansi kwezinga lokushisa elivamile, i-viscosity ye-LSR silicone cishe i-10,000, encane kakhulu kune-silicone yokubunjwa kwesikhunta,
ngakho-ke ingasetshenziswa njenge-injection yokubumba impahla eluhlaza

4. I-silicone ye-LSR ibizwa nangokuthi i-silicone yokwelapha i-platinum.Le nto eluhlaza ye-silicone isebenzisa iplatinamu njenge-catalyst ekuphenduleni kwe-polymerization.Ngeke kube khona izinto zokubola.
cishe engenalo iphunga, i-silicone ye-LSR isetshenziswa kabanzi ekwenzeni isikhunta sokudla kanye nabantu abadala.Yimpahla ye-silicone yezinga eliphezulu kakhulu kwezemvelo.

5. I-silicone ye-LSR iwuketshezi olusobala, ingasebenzisa ukhilimu wombala ovumelana nemvelo ukuze ibe nombala omuhle kakhulu.

6. I-silicone ye-LSR ingelashwa ngokushisa kwegumbi, futhi ingashiswa futhi isheshiswe.
Izinga lokushisa lesitoreji lingasuka liphansi -60 ° C lifinyelele izinga lokushisa eliphakeme lika-350 ° C, elingaphazamisi ingqikithi yalesi sibicah esinobungani bemvelo.

Izici ze-silicone zokwengeza isikhunta

1. Uhlobo lokwengeza ijeli ye-silica iyizingxenye ezimbili ze-AB.Uma uyisebenzisa, hlanganisa kokubili ngesilinganiso sesisindo esingu-1: 1 futhi ugovuze ngokulinganayo.Kuthatha imizuzu engama-30 yokusebenza kanye namahora ama-2 wesikhathi sokuphulukisa.Ingasuswa ngemva kwamahora angu-8.Sebenzisa isikhunta, noma usifake kuhhavini usishise sibe ngu-100 degrees Celsius imizuzu eyi-10 ukuze uqedele ukuphulukiswa.

2. Ukuqina kuhlukaniswe ngejeli ye-silica ethambile eyi-sub-zero ne-silica gel engu-0A-60A, enezinzuzo zokungaguquguquki okuhlala isikhathi eside kanye nokunwebeka okuhle.

3. Izinga lokushisa elivamile le-viscosity yejeli ye-silica yohlobo lokwengeza licishe libe ngu-10,000, elincanyana kakhulu kunejeli ye-silica yohlobo lwe-condensation, ngakho-ke ingasetshenziswa njengento eluhlaza yokubumba umjovo.

4. Ijeli ye-silica yohlobo lokwengeza ibizwa nangokuthi ijeli ye-silica ephulukisiwe yeplatinamu.Lolu hlobo lwe-silicone eluhlaza lusebenzisa iplatinamu njenge-catalyst ekuphenduleni kwe-polymerization.Ayikhiqizi noma yimiphi imikhiqizo yokubola.Ayinaphunga futhi isetshenziswa kabanzi ekwenzeni isikhunta sokudla kanye nemikhiqizo yocansi yabantu abadala.Yimpahla enezinga eliphakeme kakhulu lokuvikelwa kwemvelo phakathi kwamajeli e-silica.

5. Ijeli ye-silica yohlobo lokwengeza iwuketshezi olubonisa ngale, futhi imibala enemibala ingaxutshwa nokunamathisela kombala okuvumelana nemvelo.

6. I-silicone yokwengeza ingelashwa ekamelweni lokushisa noma ukushiswa ukusheshisa ukuphulukiswa.Isitoreji sansuku zonke singamelana namazinga okushisa aphansi angu -60°C namazinga aphezulu okushisa angu-350°C ngaphandle kokuphazamisa imvelo ye-silicone yezinga lokudla ehambisana nemvelo.
