Ndezvipi zvigadzirwa zvesilicone zvauri kugadzira?
--liquid silicone rabha, silicone rabha, silicone mafuta;Platinum mumiririri:
- Zvinoenderana neakasiyana silicone molds, silicone yedu ine viscosity yakasiyana, uye inokonzeresa kuoma kwakasiyana, density yekusangana nezvikumbiro kubva kune mutengi.
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.
