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.

Iyini i-ejenti yokwelapha yokwengeza irabha ye-silicone?

I-ejenti yokwelapha yokwengeza irabha ye-silicone i-platinum catalyst

Irabha ye-silicone yokwengeza ngokuvamile yelapheka ngezithako zeplatinamu, njenge-silicone yebanga lokudla, i-silicone yokubumba umjovo, njll.

Irabha ye-silicone enezingxenye ezimbili ikakhulukazi yakhiwe i-vinyl polydimethylsiloxane ne-hydrogen polydimethylsiloxane.Ngaphansi kwe-catalysis ye-platinum catalyst, ukusabela kwe-hydrosilylation kwenzeka, futhi inethiwekhi exhunywe ngokuphambana iyakhiwa.umzimba elastic

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

Izinyathelo zokuzivikela

1. Ngaphansi kwezinga lokushisa elijwayelekile, isikhathi sokusebenza sokwengeza i-silicone imizuzu engama-30, futhi isikhathi sokuphulukisa amahora ama-2.

Ungakwazi futhi ukufaka kuhhavini ongu-100-degree Celsius bese uqedela ukuphulukisa ngemizuzu eyi-10.

2. I-silicone ye-LSR ayikwazi ukuchayeka odakeni lukawoyela, i-rubber puree, amamodeli ejeli ye-UV, izinto ze-3D zokuphrinta ze-resin, isikhunta se-RTV2, ngaphandle kwalokho i-silicone ngeke iqine.
