1. Igwebu le-silicone elibunjiwe:{1}}Isinyathelo esisodwa sokubumba
Ukubunjwa kwerabha ye-silicone okubunjiwe kuyinqubo "ehlanganisiwe".
Inqubo yayo yokukhipha amagwebu kanye nenqubo yokubunjwa komkhiqizo kuqedwa ngesikhathi esifanayo futhi kusethi efanayo yokubunjwa. Inqubo ewumgogodla: Izinto zokusetshenziswa ze-silicone eziqinile ezixutshiwe futhi eziqukethe izinto ezibangela amagwebu amakhemikhali ziyakalwa ngokunembile bese zifakwa{1}}ezikhunjini zensimbi eziphezulu. Ngemuva kokuthi isikhunta sivalekile, sicindezelwe futhi sishisiwe, ukusabela okubili kwenzeka ngesikhathi esisodwa: i-vulcanization (-ukuxhumanisa) : Amaketanga emolekyuli esixhumanisi sejeli ye-silicone{4}}, ashintsha ukusuka kunjoloba eluhlaza ukuya kwirabha ekhulile futhi athola ukunwebeka. Igwebu: Amakhemikhali afaka ugwebu ayabola lapho kushisa, ekhiqiza igesi. Igesi isongwe ngejeli ye-silica evundile, eyenza inqwaba yezimbobo zamaseli{7}ezincane ezivaliwe ngaphakathi.
Izici ezibalulekile: Isendlalelo sesikhumba esiminyene: Njengoba i-silicone ithintana ngqo-nesikhunta esiphezulu{0}}sezinga lokushisa eliphezulu, ungqimba olungaphandle luvuvukala ngokushesha lube "isikhumba" esibushelelezi, esiminyene, futhi{1}}esinganamagwebu. Lolu ngqimba lwesikhumba luqinisekisa ukuthi izingxenye ezibunjiwe ezinegwebu zinekhwalithi enhle yokubukeka, ukuthinta okubushelelezi, nokuvalwa okuhle kakhulu nokumelana nokugqoka.
Izakhiwo ezinobukhulu obuthathu-eziyinkimbinkimbi: Kungenzeka ukwenza imikhiqizo ngokuqondile enezakhiwo ezinobukhulu obuthathu-ezifana ne-concave-i-concave, i-snap{3}}fit{3}}, kanye nezindawo ezigobile ezingajwayelekile, ezakheke ngokuhlangene ngaphandle kwemithungo. Ukusebenza kahle nezindleko: Ifanele ukukhiqizwa ngobuningi, ngokusebenza kahle okuphezulu ucezu ngalunye. Kodwa-ke, isikhunta sensimbi esinembile sidinga ukwenziwa, futhi izindleko zokuqala zokubumba ziphezulu kakhulu, ngakho-ke akufaneleki ukukhiqizwa kwenqwaba{6}}okuncane.
Ngamagama alula, ukubumba amagwebu kuyinqubo yokwenza "ingxenye yegwebu elibunjiwe ngesikhumba".
2.Ugwebu Lwerabha Ye-Silicone : Izindlela-ezimbili
I-silicone foaming evamile "isinyathelo--ngesinyathelo" senqubo. Iqala ikhiqize imikhiqizo esele-eqediwe (amabhodi anegwebu noma amaroli), bese icubungula ibe yimikhiqizo yokugcina njengoba kudingeka.
Inqubo eyinhloko:
Isinyathelo sokuqala: Ukukhiqiza i-substrate enegwebu. Ngemishini efana nemishini ye-calendering, izinto ze-silicone eziqukethe ama-foaming agents ziqhubeka zicutshungulwa zibe amabhodi amagwebu noma imiqulu. Le nqubo ikhiqiza ama-"silicone foam rolls" aqhubekayo futhi afanayo.
Isinyathelo Sesibili: Ukucubungula okwesibili. Ngokwezidingo zamakhasimende, lawa mabhodi anegwebu ayashaywa, aqoshwe i-CNC noma abunjwe ukuze akhe izimo ezidingekayo (njengama-gaskets, ama-sealing strips, njll.).
Izici ezibalulekile:
Ingxenye enezimbotshana eziphambanayo-: Indawo yomkhiqizo iyingxenyana-eyisiphambano yegwebu, enesakhiwo esinezimbotshana ezivulekile ngaphandle koqweqwe lwesikhumba oluminyene olutholakala ekubumbeni. Ngakho-ke, ukusebenza kwayo kokubeka uphawu nokubukeka kwayo akukuhle njengalezo zezingxenye ezibunjiwe. Umumo olula: Ikakhulukazi ikhiqiza izingxenye eziyisicaba noma ezilula ezigobile (njengama-gaskets). Kunzima kakhulu ukwenza izingxenye eziyinkimbinkimbi-ezinobukhulu obuthathu, futhi kunokumosheka okukhulu kwezinto.
Ukusebenza kahle nezindleko: Ifaneleka kakhulu-inqwaba kanye{1}}nokukhiqiza okunhlobonhlobo okuhlukahlukene{2}}kudingeka ukusika kuphela, ngezindleko eziphansi zokuqala zokutshala (asikho isidingo sokubumba ezibizayo ze-3D). Amabhodi anegwebu akhiqizwa amafekthri amakhulu anomsebenzi ofanayo kakhulu futhi ozinzile.
