RTV2 mold liquid silicone rabha yemhando dzakasiyana dzekushongedza makenduru

tsananguro pfupi:

Kushanda tembiricha yemvura mold silicone
Kushanda tembiricha yemvura mold silicone iri pakati -40 ℃ uye 250 ℃

Iyo tembiricha yekuumba yemvura silicone zvigadzirwa inotemerwa zvichienderana nehunhu hwechigadzirwa.Tembiricha yekamuri vulcanized silicone rabha inogona kukamurwa kuita condensation mhando uye yekuwedzera mhando zvinoenderana neiyo vulcanization maitiro;inogona kukamurwa kuita mhando mbiri maererano neyakarongedza nzira: maviri-chikamu uye imwechete-chikamu.Hunhu hwesilicon-okisijeni zvisungo zvinoumba cheni huru yesilicone rubber inosarudza kuti silicone rabha ine zvakanakira izvo zvakasikwa rabha uye mamwe marubha asina.Iyo ine yakakura kwazvo yekushanda tembiricha renji (-40 ° C kusvika 350 ° C) uye ine yakanakisa yakakwirira uye yakaderera tembiricha kuramba.

Iyo nzira yekukurumidza kugadzirwa kwesilicone mold zvigadzirwa ndeiyi inotevera

Zano 1. Kusarudzwa kwezvinhu: Edza kusarudza zvinhu zvakatsetseka kuita tenzi mold uye mold furemu.Iyo mold furemu inogona kugadzirwa nemapurasitiki ekuvaka zvidhinha kana acrylic mabhodhi.

Zano 2. Spray release agent: Spray release agent pane master mold.Zvakajairwa kuburitsa zvinomiririra mvura-yakavakirwa, yakaoma, uye mafuta-yakavakirwa.Kazhinji, mvura-based release agents uye resin-based release agents anoshandiswa kugadzira mold sematombo akagadzirwa uye kongiri.Shandisa yakaoma (inonziwo kusarerekera) kuburitsa mumiririri, polyurethane mhando shandisa mafuta ekuburitsa mumiriri, kana chidimbu chidiki cheforoma chakapindurwa, unogona zvakare kushandisa sipo yedhishi kana sipo mvura pachinzvimbo.

Zano rechitatu: Vhura mold mushure mekusimba kwakazara: Sezvo nzira yekurapa yesilicone yemvura ichibva pakugadzika kwekutanga kusvika pakusimba, vanhu vazhinji vari kuyedza kutenderedza mold vanovhura mold pakarepo mushure mekutanga kusimba.Panguva ino, iyo silicone haina kusimba zvachose uye inogona kungove yakanyatso kusimba.Kana iyo yemukati layer isina kuporeswa, kumanikidza mold kuvhurika panguva ino zvakare kukonzeresa matambudziko nechikamu chakapora mucous membrane.Naizvozvo, zvinowanzokurudzirwa kuvhura mold mushure memaawa gumi nemaviri kusvika makumi maviri nemana.Izvi zvinogona zvakare kudzivirira dambudziko re deformation kana kuwedzera shrinkage yesilicone mold..

Zano 4: Sarudza iyo silicone yakakodzera: Paunenge uchishandisa liquid silicone kuumba transparent epoxy resin zvigadzirwa zvemaoko, unofanirwa kusarudza iyo silicone chaiyo.Kana uri kushandisa condensation liquid silicone uye uine matambudziko ekunamira mold, unogona kuisa silicone mold muovheni.Bika mold pane tembiricha yepakati (80 ℃-90 ℃) kwemaawa maviri, zvichienderana nehukuru hwesilicone mold.Zvadaro, mirira kuti silicone mold itonhore uye wozoshandisa epoxy resin kugadzirisa dambudziko rekunamatira mold.Kana iwe uri kushandisa yekuwedzera mvura mold silicone, dambudziko rekunamatira mold nderekuti silicone mold kana master prototype haina kuchena zvakakwana, kana kuti pane dambudziko nemhando yesilicone kana resin.

Zvikonzero nei mold silicone isingaomese

Zvikonzero nei mold silicone isingaome inogona kunge iri nekuda kweanotevera mapoinzi matatu: 1:

Tembiricha yakadzikira.Liquid silicone ichanetsa kuomesa pasi pe10°C.Izvi zvinowanzoitika zvakanyanya munguva yechando.Muchiitiko ichi, inogona kugadziriswa nekusimudza tembiricha yekamuri kusvika pamusoro pe20 ℃.

Hardener ratio haina kunaka.Kazhinji, reshiyo ye condensation-mhando silica gel kune inorapa mumiririri i100:2.Kana reshiyo yeanorapa ajenti yakawedzerwa idiki kwazvo, haizokonzerese kurapa kana kunetsa mukurapa.Pamusoro pezvo, mushonga unorapa unopihwa nemugadziri kazhinji huremu hwehuremu kwete chiyero chevhoriyamu.
Iyo silicone gel uye mumiririri wekurapa haina kunyatso kusanganiswa zvakaenzana.Kana musanganiswa usina kuzunguzwa zvakaenzana, zvinowanzokonzera kusimba kwechidimbu uye kusasimba.Nokudaro, paunenge uchikurudzira, teerera kune yakasara silicone pamakona emudziyo.
