1. Chithovu cha silikoni: Njira imodzi-yowumba
Kupangidwa kwa mphira wa silicone wopangidwa ndi thovu ndi njira "yophatikizika".
Njira yake yotulutsa thovu ndi kupanga mapangidwe azinthu zimamalizidwa nthawi yomweyo komanso mumagulu omwewo. Cholinga chachikulu: Zida zolimba za silikoni zomwe zasakanizidwa ndipo zimakhala ndi zinthu zotulutsa thovu zimapimidwa ndendende ndikuziika-mu zitsulo zotentha kwambiri. Chikombole chikatsekedwa, kutenthedwa ndi kutentha, zochitika ziwiri zimachitika nthawi imodzi: vulcanization (mtanda-kulumikiza) : The molecular chain of the silikoni gel cross-link, kusinthika kuchoka ku rabara yaiwisi kupita ku mphira wokhwima ndikukula. Kuchita thovu: Mankhwala otulutsa thovu amawola akatenthedwa, ndikupanga mpweya. Mpweyawu umakulungidwa ndi silika wopangidwa ndi vulcanized, kupanga timabowo tating'ono tating'ono tating'ono timene timatsekeka-mkati mwake.
Zofunika kwambiri: Khungu lowundana: Pamene silikoni imagwirana ndi-kutentha kwapamwamba, wosanjikiza wakunjayo amanjenjemera ndi kupanga "khungu" losalala, lowundana, komanso losakhala{1}}lopanda thovu. Khungu ili limapangitsa kuti ziwalo zopangidwa ndi thovu zikhale ndi maonekedwe abwino, kukhudza kosalala, komanso kusindikizidwa bwino komanso kusavala.
Zovuta kwambiri-zokhala ndi magawo atatu: Ndizotheka kupanga mwachindunji zinthu zokhala ndi zopinga zitatu{1}}zowoneka ngati concave-zowoneka bwino, zowoneka bwino-zokwanira, ndi zokhotakhota zosakhazikika, zomwe zimapangika popanda kusokoka. Kuchita bwino komanso mtengo wake: Oyenera kupanga zambiri, ndikuchita bwino pachidutswa chilichonse. Komabe, nkhungu zachitsulo zenizeni ziyenera kupangidwa, ndipo mtengo wake woyamba ndi wokwera kwambiri, choncho siwoyenera kupanga{6}}magulu ang'onoang'ono.
M'mawu osavuta, kuumba thovu ndi njira yopangira "gawo lopangidwa ndi thovu lopangidwa ndi khungu".
2.Conventional Silicone Rubber Foaming : Njira ziwiri-ziwiri
Silicone thovu wamba ndi "sitepe-ndi-pang'onopang'ono". Imayamba kupanga zinthu zomaliza-zomaliza (mabokosi a thovu kapena ma rolls), kenaka amazipanga kukhala zomaliza ngati pakufunika.
Core process:
Khwerero 1: Kupanga gawo lapansi la thovu. Kudzera m'zida monga makina owerengera, zida za silikoni zomwe zimakhala ndi thovu zimasinthidwa mosalekeza kukhala matabwa kapena mipukutu. Izi zimapanga mosalekeza komanso zofananira za "silicone foam rolls".
Khwerero 2: Kukonzekera kwachiwiri. Malinga ndi zomwe makasitomala amafuna, matabwa okhala ndi thovuwa amakhomeredwa, CNC amalembedwa kapena kuumbidwa kuti apange mawonekedwe ofunikira (monga ma gaskets, mizere yosindikiza, ndi zina).
Zofunikira zazikulu:
Porous cross-gawo: Pamwamba pa chinthucho ndi chopingasa-gawo cha thovu, chokhala ndi povunda lotseguka lopanda khungu lowundana lomwe limapezeka powumba. Chifukwa chake, mawonekedwe ake osindikiza komanso mawonekedwe ake sizowoneka bwino ngati a magawo owumbidwa. Mawonekedwe osavuta: Amapanga magawo athyathyathya kapena opindika (monga ma gaskets). Ndizovuta kwambiri kupanga magawo atatu{5}}ovuta kwambiri, ndipo pali kuwonongeka kwakukulu kwa zinthu.
Kuchita bwino ndi mtengo wake: Ndiwoyenera kwambiri-magulu ang'onoang'ono komanso angapo{1}}kupanga mitundu yosiyanasiyana monga kufa kokha{2}}kudula kumafunika, ndi mtengo wotsikirapo woyambira (palibe kufunikira kwa ma 3D molds okwera mtengo). Ma board a thovu opangidwa ndi mafakitale akulu amakhala ndi magwiridwe antchito ofanana komanso okhazikika.
