Ihoyili ye-DIY Resin Ukugalela ubucwebe bezacholo ulwelo Irabha yeSilicone

inkcazelo emfutshane:

Ukulumkela:

1. Phantsi kobushushu obuqhelekileyo, ixesha lokusebenza lokongeza i-silicone yimizuzu engama-30, kwaye ixesha lokunyanga ziiyure ezi-2.Ungafaka kwi-oven ye-100-degree Celsius kwaye ugqibezele ukunyanga ngemizuzu eyi-10.

2. I-silicone ye-LSR ayinakuvezwa eludakeni lweoyile, ipuree yerabha, imifuziselo yejeli ye-UV, i-3D yoshicilelo lwe-resin, i-RTV2 molds, kungenjalo i-silicone ayiyi kuqina.

LSR 1:1 abicah ngundo ukwenza umyalelo wokusebenza

1. Iimodeli zokucoca kunye nokulungiswa
2. Yenza isakhelo esisisigxina somzekelo kwaye ugcwalise i-gap nge-hot melt glue gun
3. Sitshiza i-ejenti yokubumba imodeli yokuthintela ukunamathela
4. Hlanganisa ngokupheleleyo kwaye ugxobhoze i-A kunye ne-B ngokomlinganiselo wobunzima be-1: 1 (vuselela kwicala elinye ukukhusela ukungena emoyeni kakhulu)
5. Beka i-silicone edibeneyo kwibhokisi ye-vacuum kwaye ukhuphe umoya
6. Thela i-silicone kwibhokisi esisigxina
7. Emva kweeyure ezi-8 zokulinda, ukuqiniswa kugqityiwe, emva koko kususa imodeli

Ixabiso elenziwayo i-RTV-2 irabha elulwelo yesilicone yokwenza umngundo kunye nomgangatho wokutya okumgangatho ophezulu wokunyanga i-silicone-02 (5)

Iimpawu ze-silicone ze-LSR

I-silicone ye-1.LSR yi-AB yecandelo elibini leqela, lixutywe kwaye lixutywe ngokulinganayo i-A kunye ne-B ngomlinganiselo wobunzima be-1: 1, .
Ixesha lokusebenza yi ~ 30 imizuzu, ixesha lokunyanga yi ~ iiyure ezi-2, kunye nokukhupha umngundo kwiiyure ezisi-8.

2. Ubunzima buhlukaniswe: i-silicone ethambileyo kakhulu -ngaphantsi kwe-0A, i-0A-60A yokubumba i-silicone,
ineengenelo zombala omde kunye nokunwebeka okukhulu3.Ngaphantsi kobushushu obuqhelekileyo, i-viscosity ye-silicone ye-LSR imalunga ne-10,000, enqabileyo kakhulu kune-silicone yokubumba i-condensation,
ngoko ke inokusetyenziswa njengenaliti yokubumba imathiriyeli ekrwada

4. I-silicone ye-LSR ikwabizwa ngokuba yi-silicone yokuphilisa i-platinum.Le mpahla eluhlaza ye-silicone isebenzisa iplatinam njenge-catalyst kwi-polymerization reaction.Akuyi kubakho zinto zokubola.
phantse akukho nevumba, i-silicone ye-LSR isetyenziswa ngokubanzi ukwenza ukungunda kokutya kunye nabantu abadala.Yeyona ndawo iphakamileyo ye-silicone imathiriyeli.

5. I-silicone ye-LSR lulwelo olucacileyo, inokusebenzisa ikhrimu yombala ehambelana nokusingqongileyo ukuya kumbala obalaseleyo.

6. I-silicone ye-LSR inokunyangwa ngubushushu begumbi, nayo inokufudunyezwa kwaye ikhawuleze.
Ubushushu bokugcina bunokusuka kwi-low -60 ° C ukuya kuthi ga kwiqondo lobushushu obuphezulu be-350 ° C, obungachaphazeli undoqo we-abicah ehambelana nokusingqongileyo.

I-agent ephilisayo yokongeza irabha ye-silicone yi-platinum catalyst

Irabha eyongeziweyo ye-silicone inyangwa ikakhulu ngeplatinam, njenge-silicone yebakala lokutya, i-silicone yokubumba inaliti, njl.

I-rubber ye-silicone eyongeziweyo yamacandelo amabini iqulunqwe kakhulu nge-vinyl polydimethylsiloxane kunye ne-hydrogen polydimethylsiloxane.Ngaphantsi kwe-catalysis ye-platinum catalyst, i-hydrosilylation reaction iyenzeka, kwaye inethiwekhi edibeneyo ifakwe.umzimba elastic
