Mastering Mold Creation with Addition-Cure Silicone: A Comprehensive Guide

Kupanga zisankho moyenera komanso modalirika ndi luso lomwe limaphatikizapo kusankha zinthu zoyenera ndikutsata mosamala.Silicone yochiritsira yowonjezera, yomwe imadziwika ndi kusinthasintha kwake komanso kugwiritsa ntchito bwino, yakhala yotchuka kwambiri pakati pa amisiri ndi opanga.Mu bukhuli lathunthu, tifufuza njira yopangira nkhungu ndi silicone yowonjezera, kuwonetsetsa zotsatira zabwino.

Khwerero 1: Yeretsani ndi Kuteteza Nkhungu

Ulendo umayamba ndi kuyeretsa mosamala nkhungu kuti athetse zonyansa zilizonse.Mukayeretsa, sungani bwino nkhunguyo m'malo mwake, kuteteza kusuntha kulikonse kosafunika panthawi yotsatila.

Gawo 2: Pangani Mafelemu Olimba

Kuti mukhale ndi silikoni panthawi yakuumba, pangani chimango cholimba kuzungulira nkhungu.Gwiritsani ntchito zinthu monga matabwa kapena pulasitiki kuti mupange chimango, kuonetsetsa kuti chikuphimba nkhunguyo.Lembani mipata iliyonse mu chimango ndi mfuti yotentha ya glue kuti muteteze kutayikira kwa silicone.

Khwerero 3: Ikani Wotulutsa Mold

Thirani chinthu choyenera kumasula nkhungu pa nkhungu.Gawo lofunikirali limalepheretsa silicone kuti isamamatire nkhungu, ndikuwonetsetsa kuti njira yobowola yosalala komanso yopanda kuwonongeka.

Khwerero 4: Sakanizani zigawo za A ndi B

Potsatira kulemera kwa 1: 1, sakanizani bwino zigawo za A ndi B za silicone.Limbikitsani mbali imodzi kuti muchepetse kuyambitsa kwa mpweya wochuluka, kuonetsetsa kuti kusakanikirana kofanana.

Khwerero 5: Vacuum Deaeration

Ikani silikoni yosakanikirana mu chipinda chochotseramo mpweya kuti muchotse thovu la mpweya.Vacuum deaeration ndiyofunikira kuti muchotse mpweya uliwonse wotsekeredwa mumsanganizo wa silikoni, kutsimikizira malo opanda cholakwika mu nkhungu yomaliza.

Khwerero 6: Thirani mu chimango

Mosamala tsanulirani silicone ya vacuum-degassed mu chimango chokonzekera.Izi zimafuna kulondola kuti mpweya usatseke, kuonetsetsa kuti nkhunguyo ikhale yofanana.

Khwerero 7: Lolani Kuchiritsa

Khalani oleza mtima ndikulola silicone kuti ichire.Nthawi zambiri, nthawi yochiritsa ya maola 8 imafunika kuti silikoni ilimbe ndikupanga nkhungu yolimba komanso yosinthika yokonzeka kugwetsedwa.

Malangizo Owonjezera:

1. Nthawi Yogwira Ntchito ndi Kuchiritsa:

Nthawi yogwira ntchito yowonjezera-chiza silicone kutentha kwapakati ndi pafupifupi mphindi 30, ndi nthawi yochiritsa ya maola awiri.Kuti muchiritsidwe mwachangu, nkhungu imatha kuyikidwa mu uvuni wa preheated pa 100 ° C kwa mphindi 10.

2. Chenjezo Lokhudza Zida:

Silicone yowonjezera-mankhwala sayenera kukhudzana ndi zinthu zina, kuphatikizapo dongo lopangidwa ndi mafuta, dongo la mphira, zida za UV resin nkhungu, zipangizo zosindikizira za 3D, ndi RTV2.Kukhudzana ndi zinthu izi kungalepheretse kuchiritsa bwino kwa silikoni.

Kutsiliza: Kupanga Ungwiro ndi Silicone Yowonjezera-Cure

Potsatira mosamalitsa masitepewa ndikutsatira malangizo omwe aperekedwa, amisiri ndi opanga amatha kugwiritsa ntchito mphamvu ya silicone yowonjezerapo kuti apange nkhungu mwatsatanetsatane komanso modalirika.Kaya mukupanga ma prototypes otsogola kapena kutulutsanso ziboliboli zatsatanetsatane, njira yowonjezera yochizira silikoni imatsegula mwayi wambiri wowonetsa luso komanso kupanga bwino.
