LSR 1: 1 litaelo tsa ho etsa hlobo ea silicone
1. Ho hloekisa mehlala le ho lokisa
2. Etsa foreimi e tsitsitseng bakeng sa mohlala 'me u tlatse lekhalo ka sethunya sa glue se chesang
3. Spray molding agent bakeng sa mohlala ho thibela ho khomarela
4. Kopanya ka ho feletseng 'me u tsose A le B ho ea ka tekanyo ea boima ba 1: 1 (hlohlelletsa ka tsela e le' ngoe ho thibela ho kena moeeng o mongata)
5. Kenya silicone e tsoakiloeng ka lebokoseng la vacuum 'me u ntše moea
6. Tšela silicone ka lebokoseng le tsitsitseng
7. Ka mor'a lihora tse 8 tsa ho leta, ho tiisa ho phethehile, ebe o tlosa mohlala
Litšobotsi tsa silicone tsa LSR
Silicone ea 1.LSR ke karohano ea lihlopha tse peli tsa AB, tse kopantsoeng le ho tsosoa ka ho lekana A le B ka tekanyo ea boima ba 1: 1, .
Nako ea ts'ebetso ke ~ metsotso e 30, nako ea ho folisa ke ~ lihora tse 2, 'me u tlose hlobo ka lihora tse 8.
2. Ho thatafala ho arotsoe ka: silicone e bonolo haholo -e ka tlaase ho 0A, 0A-60A mold silicone,
e na le melemo ea nako e telele ea 'mala le elasticity e kholo3.Tlas'a mocheso o tloaelehileng, viscosity ea silicone ea LSR e ka ba 10,000, e fokolang haholo ho feta silicone ea hlobo ea condensation,
kahoo e ka sebelisoa e le ente e bōpa thepa e tala
4. Silicone ea LSR e boetse e bitsoa silicone ea ho phekola platinum.Sehlahisoa sena se tala sa silicone se sebelisa platinum e le mohloli oa karabelo ea polymerization.Ha ho na ho ba le lintho tse bolang.
e batla e se na monko, silicone ea LSR e sebelisoa haholo ho etsa hlobo ea lijo le batho ba baholo.Ke thepa ea silicone ea boemo bo holimo ka ho fetisisa tikolohong.
5. Silicone ea LSR ke mokelikeli o bonaletsang, o ka sebelisa tranelate ea 'mala e lumellanang le tikoloho ho ea mebala e metle haholo.
6. Silicone ea LSR e ka phekoloa ka mocheso oa kamore, hape e ka futhumatsa le ho potlakisa.
Mocheso oa polokelo o ka tloha tlase ho -60 ° C ho ea ho mocheso o phahameng oa 350 ° C, o sa ameng moelelo oa silicone ea lijo-thollo e nang le botsoalle ba tikoloho.
Sepheko sa pheko bakeng sa rabara ea silicone ea tlatsetso ke eng?
Moemeli oa pheko oa tlatsetso ea rabara ea silicone ke platinum catalyst
Rabara ea Silicone e ekelitsoeng hangata e phekoloa ka li-catalysts tsa platinum, joalo ka silicone ea boemo ba lijo, silicone ea ho bopa ente, jj.
Rabara ea silicone ea likarolo tse peli e entsoe haholo ka vinyl polydimethylsiloxane le hydrogen polydimethylsiloxane.Tlas'a catalysis ea catalyst ea platinum, ho etsahala karabelo ea hydrosilylation, 'me marang-rang a marang-rang a thehoa.'mele o otlolohileng
