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 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.

I-LSR 1:1 imiyalelo yokwenza isikhunta se-silicone

1. Ukuhlanza amamodeli nokulungisa
2. Yenza ifreyimu ehleliwe yemodeli bese ugcwalisa igebe ngesibhamu se-glue esishisayo esishisayo
3. Futha i-ejenti yokubumba yemodeli ukuvimbela ukunamathela
4. Hlanganisa ngokugcwele futhi uvuse u-A no-B ngokwesilinganiso sesisindo esingu-1: 1 (goqa ohlangothini olulodwa ukuze uvimbele ukungena emoyeni omningi)
5. Faka i-silicone ehlanganisiwe ebhokisini le-vacuum bese ukhipha umoya
6. Thela i-silicone ebhokisini elilungisiwe
7. Ngemuva kwamahora angu-8 wokulinda, ukuqinisa kuqedile, bese kususa imodeli
