Tsis ntev los no, silicone pwm tau siv ntau ntxiv, uas yog qhov txawv ntawm qhov tseeb tias nws hardens nyob rau hauv chav tsev kub tsis shrinking thiab cov ntaub ntawv roj hmab. Rau kev tsim cov pwm hauv tsev, koj tuaj yeem siv ob lub ntsiab lus.
Silicone roj hmab thiab cov khoom sib txuas tau yooj yim hloov mus rau hauv pwm hauv tsev, tsis tas yuav tsum muaj cov khoom siv ntxiv, vim tias lawv tso cai rau kev ywj pheej ntawm phau ntawv nchuav. Yog li, silicone rau pwm yog siv rau ntau lub hom phiaj, koj tuaj yeem xav txog kev luam cov khoom yooj yim. Pib nrog, koj tuaj yeem nrum ib feem ntawm epoxy rau hauv cov pwm cais, uas muaj ob ntu.
Thaum tus nqi pheej yig thiab ntau hom silicone sealant zoo haum rau kev ua haujlwm no, nws yooj yim dua thiab yooj yim dua los siv ob lub ntsiab lus uas tau tsim tshwj xeeb rautsim cov ntawv. Epoxy resin kuj tseem siv rau casting. Muaj ntau ntawm cov khoom siv no nyob rau hauv kev ua lag luam, yog li thaum xaiv nws yog ib qho tseem ceeb uas yuav tsum tau coj mus rau hauv tus account xws li qhov yuav tsum tau ua tsis luv luv lub sij hawm polarization. Yog tias siv ob feem pwm silicone, tus neeg sawv cev tso tawm yuav tsum tau ua kom cov halves sib cais ntawm ib leeg.
Tam sim no, muaj ntau yam khoom sib cais uas tau tsim tshwj xeeb rau lub hom phiaj no. Lawv feem ntau yog nyob rau hauv daim ntawv ntawm wax-based aerosols, tab sis tsis tu ncua melted ciab los yog roj av jelly kuj siv tau.
Plasticine tuaj yeem ua cov khoom siv hauv tsev hauv qhov no. Ua ntej koj pib ua pwm, koj tuaj yeem tshawb xyuas cov ntaub ntawv xaiv kom sib xws. Nyob rau hauv cov kev tshwm sim hais tias qhov no nuance yog tsis, koj muaj peev xwm ua lwj tag nrho cov hauj lwm. Koj yuav tsum xyuas kom meej tias cov silicone tawm tau yooj yim los ntawm ib qho chaw ua los ntawm tib yam khoom raws li qhov koj xav luam. Yog tias qhov no tsis ua haujlwm, ces nws yuav tsum tau them nrog tus neeg sawv cev tso tawm. Tom ntej no, nws yog ib qho tseem ceeb kom paub tseeb tias cov epoxy cais zoo los ntawm silicone tom qab kho, thiab lub cev lub cev ntawm cov khoom yog txaus siab tom qab kho. Tsuas yog tom qab ntawd tuaj yeem siv molding silicone.
Cov txheej txheem tsim khoom pib nrog qhov tseeb tias plasticine yog siv rau hauv qhov chaw tiaj tus, uas yuav tsum tau nias lub tshuab luam ntawv. Yog hais tias peb tham txog ib feem tiaj tus, ces nws yuav nias mus txogciam teb uas daim ntawv yuav muab faib. Yog hais tias nws yog voluminous txaus, ces koj yuav tsum tau siv lwm txheej ntawm plasticine nyob ib ncig ntawm lub perimeter. Cov khoom yuav tsum raug nias zoo tiv thaiv ib feem, uas yuav tso cai rau tsim cov ciam teb sib txawv.
Ua ntej siv silicone rau pwm, nws yog ib qho tsim nyog yuav tsum tau ua cov phab ntsa ntawm lub thawv yav tom ntej, uas yog siv tib lub plasticine. Nyob rau hauv qab ntawm lub thawv, koj tuaj yeem ua ob peb qhov chaw so kom cov halves tuaj yeem tau docked rau ib leeg. Tam sim no hais tias txhua yam yog npaj txhij rau pouring, nws yog heev muaj peev xwm siv kua silicone rau pwm. Tom qab hardening, koj tuaj yeem tshem tawm tag nrho cov plasticine, vim li ntawd, tsuas yog cov pwm silicone tseem nyob.
