Liquid Silicone Molding

Liquid silicone

Liquid silicone rabara ke mofuta o phahameng oa 'mele oa' mele o hloekisitsoeng o nang le khatello e tlase, botsitso bo boholo le bokhoni ba ho hanyetsa mocheso o feteletseng le serame se loketseng tlhahiso ea likarolo, moo boleng bo phahameng bo tlamehang. Ka lebaka la sebopeho sa thepa, mofuta oa silicone oa ho enta ka metsi o hloka kalafo e khethehileng, joalo ka ho kopanya ho tebileng, ha o ntse o boloka thepa ka mocheso o tlase pele e phuthulloa.

Likopo tse tloaelehileng

Likopo tse tloaelehileng tsa rabara ea silicone ea metsi ke lihlahisoa tse hlokang ho otloloha ka mokhoa o phahameng joalo ka litiiso, ho manama litšila, likhokahanyo tsa motlakase, likhokahano tse nang le lipini tse ngata, lihlahisoa tsa masea moo ho batloang libaka tse boreleli, joalo ka mabotlolo a botlolo, lits'ebetso tsa bongaka hammoho le thepa ea kichineng joalo ka ho baka. lipane, li-spatulas, jj. Hangata, rabara ea silicone e tšoloheloa likarolong tse ling tse entsoeng ka polasetiki e fapaneng. Mohlala, sefahleho sa konopo ea silicone se ka fetisetsoa ntlong ea Nylon e 6,6.

Kahemo

Ka khemikhale, rabara ea silicone ke lelapa la li-elmometer tsa thermoset tse nang le mokokotlo oa alternating silicon le liathomo tsa oksijene le lihlopha tsa mahlakore a methyl kapa a vinyl. Li-rubic tsa Silicone li theha karolo ea 30% ea lelapa la silicone, e ba etsang sehlopha se seholo sa lelapa leo. Li-ruble tsa silicone li boloka thepa ea tsona ea mochini ka holim'a mocheso o mongata le ho ba teng ha lihlopha tsa methyl ho li-rubic tsa silicone ho etsa hore lisebelisoa tsena li be hydrophobic haholo, li etse hore li tšoanelehe bakeng sa ho kenella ha motlakase.

Litšobotsi tsa LSR

Ho etsa lintho ka mefuta-futa: Tlas'a tlhahlobo e pharaletseng, rabara ea silicone ea metsi e bontšitse tšebelisano e phahameng le lithane tsa motho le metsi a 'mele. Ha ho bapisoa le li-elastomers tse ling, LSR e hanana le kholo ea baktheria mme e ke ke ea senya le ho theola lisebelisoa tse ling. LSR hape ha e na mafome ebile ha e na monko ebile e ka etsoa hore e lumellane le litlhoko tse thata tsa FDA. Lingoloa li ka silafatsoa ka mekhoa e fapaneng, ho kenyelletsa mouoane o ikemetseng, ethylene oxide (ETO), gamma, e-beam le mekhoa e meng e mengata, ho fihlela tumellano e hlokahalang joalo ka BfR XV, FDA 21 CFR 177.2600, USP Class VI.

E tšoarellang

Likarolo tsa LSR li khona ho mamella mocheso o feteletseng, o li etsang khetho e nepahetseng bakeng sa likarolo tse tlasa hofi ea likoloi le haufi le enjine. Likarolo tse entsoeng ka metsi a tsoang ka ente ea silicone ea rabara ha li na mollo hape li ke ke tsa qhibiliha.

Khahlano le lik'hemik'hale

Liquid silicone rabara e hanyetsa metsi, oxidation le tharollo ea lik'hemik'hale tse kang acid le alkali

Ho hanyetsa mocheso

Ha e bapisoa le li-elastomers tse ling, silicone e khona ho mamella mocheso o mongata o phahameng / o tlase haholo.

Lisebelisoa tsa mochini

LSR e na le bolelele bo botle, ho taboha ho hoholo le ho tepella, ho tenyetseha le maemo a boima ba 5 ho isa ho 80 Shore A.

Thepa ea motlakase

LSR e na le thepa e ntle ea ho futhumatsa, e fanang ka khetho e ipiletsang bakeng sa lits'ebetso tse ngata tsa motlakase. Ha e bapisoa le thepa e tloaelehileng e futhumatsang, silicone e ka sebetsa ka litheko tse phahameng haholo le tse tlase.

Sekhahla le pigmentation

LSR e na le ponaletso ea tlhaho, tšobotsi ena e etsa hore ho khonehe ho hlahisa, lihlahisoa tse mebala, tsa setso, tse bopehileng

Melemo ea LSR

 Matla a batches (lisebelisoa tse itokiselitseng ho sebelisa)

 Ho pheta-pheta

 Ente e tobileng (ha ho na litšila)

 Nako e khutšoane ea potoloho

 Mahlale a 'Flashless' (ha ho na libapali)

Ts'ebetso e ikemetseng

Lits'ebetso tse ikemetseng tsa demolding

Boleng bo tsitsitseng
