1) Kev npaj thiab cov khoom sib xyaw
Pib los ntawm kev ntsuas koj cov khoom kom raug. Rau txhua 100 g ntawmSilicone molding XG-360W-1, 10 g ntawmXG-360WB-1 catalyst(10: 1 puag rau catalyst) thiab kwv yees li 25% thinner (XG-X1000) txheeb ze rau lub ntim silicone. Cov kauj ruam thinning no txhim kho cov silicone ntws, kom ntseeg tau tias cov kab sib txuas thiab cov duab zoo ib yam, tshwj xeeb tshaj yog cov ntsiab lus zoo.
Sib tov kom huv si kom txog thaum lub catalyst thiab thinner yog tag nrho incorporated thiab cov xim thiab viscosity yog uniform. Kev sib xyaw kom zoo tiv thaiv cov pob tsis zoo thiab ua kom tus cwj pwm kho kom zoo. Thaum cov xim yuav tsum tau (piv txwv li, xim liab rau lub hauv paus), ntxiv rau lawv thaum lub sij hawm no kom cov xim sib xws nyob rau hauv txhua pawg.
2) Dispensing Setup
Thaum koj cov khoom sib tov silicone npaj txhij, hloov mus rau qhovdispensing tshuab. Dispensing tshuab siv nyob rau hauv ob- cov khoom siv silicone yog tsim los ntsuas thiab sib tov siab - cov ntaub ntawv viscosity nyob rau hauv kev tswj lub siab thiab qhov sib piv, muab cov ntaub ntawv meej ncaj qha rau hauv pwm lossis rau hauv cov khoom siv.
Program lub dispenser raws li lub logo tsim: qhia qhov ntim ntawm silicone, dispense txoj kev, ceev, thiab piv chaw. Kev suav nrog cov thinner yuav tsum tau muab xam rau hauv tag nrho rheology thiab txaus tus nqi, vim qhov no cuam tshuam li cas cov silicone mus los ntawm hoses thiab nozzles.
3) Sau cov pwm thiab siv cov silicone
Nrog lub tshuab dispensing calibrated, pib sau cov pwm kab noj hniav nrog cov silicone sib tov. Cov pwm yuav tsum huv si, ua ntej- npaj, thiab yog tias tsim nyog, kho nrog pwm- tso tawm tus neeg sawv cev los yog zaj duab xis kom yooj yim demolding tom qab kho. Txawm hais tias tsis tas yuav tsum tau ua, cov txheej txheej nyias nyias tuaj yeem txuas lub neej pwm thiab txo cov khib nyiab.
Muab faibdawb silicone rau lub logo tivthaiv ua ntej- qhov no muab lub hauv paus huv si, opaque uas yuav tom qab tsim los yog sau nrog cov xim liab silicone. Tam sim ntawd ua raws li kev thovliab silicone rau keeb kwm yav dhau los yog accents. Lub tshuab hluav taws xob ua kom ntseeg tau tias ob cov ntaub ntawv no tau muab tso nrog cov khoom tsim tawm thiab cov khoom pov tseg tsawg.
4) Npog nrog Kub Melt Zaj duab xis
Thaum cov silicone yog dispensed,npog lub pwm puv nrog ib zaj duab xis kub yaj. Cov yeeb yaj kiab no ua haujlwm ntau yam:
Nws tiv thaiv silicone nto,
Nws muab cov cab kuj rau tom qab cua sov- nias rau ntawm ntaub,
Thiab nws pab tswj cov duab thaum lub sij hawm vulcanization txheej txheem.
Txiav cov yeeb yaj kiab kub yaj kom meej rau qhov loj me, muab tso rau hauv cov silicone, thiab xyuas kom tsis muaj wrinkles los yog lub hnab ntim cua ua ntej txav mus rau theem kho.
5) Kev kho (Vulcanization)
Hloov cov pwm nrog silicone thiab kub yaj zaj duab xis rau hauvvulcanizing (kub xovxwm) tshuab. Siv tau zoo silicone pwm curing cia siab rau kev tswj qhov kub thiab txias kom pib thiab ua tiav crosslinking. Hauv theem no:
Cov silicone hloov los ntawm viscous muab tshuaj txhuam rau hauv daim ntawv elastomeric khoom.
Thaum tshav kub kub thiab siab interlinks polymer chains, tsim kom muaj zog txhua yam muaj zog.
Cov txheej txheem kub hloov pauv tswj qhov kub pwm sab saud zoo tshaj qhov nruab nrab thiab siv cov pwm qis dua ua ib feem ntawm lub voj voog. Qhov ntsuas kub thiab lub sijhawm nyob yog nyob ntawm qhov tsim thickness thiab silicone formulation, tab sis rau ntau cov txheej txheem silicone molding, cov pwm sab sauv kub yog nyob rau hauv 150-180℃ntau yam nrog nias lub sij hawm ntawm ob peb feeb mus rau feeb.
Tom qab lub voj voog xovxwm, cia cov pwm kom txias ua ntej sim demolding. Txias stabilizes silicone thiab tiv thaiv distortion.
