Chimiro chetatu: silicon methyl boka inokosha

Methyl silicon carbon bond ndiyo yakanyanya kugadzikana silicon carbon bond; Kuvapo kwesilicone methyl kunopa silicone mafuta akasiyana zvivakwa; Mhando dzose dzesilicone oiri zvinobva kune methyl silicone mafuta; Mafuta e-silicone anotorwa anotumidzwa zita remapoka kunze kwemapoka emethyl.

Silicon mafuta classification

Inert silicone mafuta:mukushandiswa kazhinji haibatanidzi mukuita kwemakemikari, zvakanyanya kushandiswa kwezvinhu zvemuviri zvesilicone oiri, pane makemikari zvinhu. Zvakadai se: methyl silicone oiri, phenyl silicone mafuta, polyether silicone mafuta, refu alkyl silicone mafuta, trifluoropropyl silicone mafuta, ethyl silicone mafuta, nezvimwe.

Reactive silicone oiri: ine rakajeka reactive boka, rinowanzobatanidzwa mumakemikari maitiro ari kushandiswa.
Zvakadai se: hydroxysilicone oiri, vinyl silicone mafuta, hydrogen silicone oiri, amino silikoni mafuta, sulfhydryl silicone mafuta. Silicone oiri imhando yakakosha yemafuta emafuta ane silicon kabhoni bond uye silicon silicon bond. Silicon methyl inopa basa repamusoro, hydrophobic, uye kusunungurwa; silicon chimiro chinopa kugadzikana (inert) uye yakanakisa magetsi emagetsi.

Common silicone oiri sumo
methylsilicone mafuta
Tsanangudzo:Mapoka ese ari muchimiro chemolecular ma methyl mapoka.
Features:kugadzikana kwakanaka kwekushisa; dielectric yakanaka; hydrophobicity; viscosity uye kusvibiswa. Iyo inonyanya kukosha yekutengesa, silicone mafuta (201, DC200, KF 96, TSF451).
Kugadzirira nzira:Gadzirira nekushandisa equilibrium reaction.
Characterization zvinoreva:iyo viscosity inowanzoshandiswa kumiririra iyo polymerization yesilicone oiri, iyo viscosity inoshandiswa kusiyanisa zvigadzirwa, iyo inoenderera synthesis yeviscosity methyl silicone mafuta pazasi 50mPa.s.
Kugadzirira zvinhu:50mPa.s Commercial methylsilicone mafuta, hexamethyldisiloxane (head agent), macroporous acid cationic resin.
flash system.
Kugadzirira mudziyo:a reaction column izere neresin, vacuum flash system.
Muchidimbu maitiro:Sanganisa iyo methyl silicone oiri uye mumiriri wekuparadzanisa muchiyero kuburikidza nekoramu yekuita, uye penya kuti utore iyo yapera silicone mafuta.

ine hydrogen silicone mafuta.

Reactive silicone oiri ine iyo Si-H bond (KF 99, TSF484)
Zvikamu zviviri zvakajairika:

Kugadzirira neasidhi chiyero nzira:

Main kushandiswa:silicon hydrogen yekuwedzera raw material, silicone rabha additives, waterproof treatment agent.

Amino silicone mafuta
Tsanangudzo:a reactive silicone mafuta ane hydrocarbon amino boka.
Common structural units:

Main kushandiswa:kupedzisa jira, mold kuburitsa agent, cosmetics, organic modification.

Vinyl silicone mafuta

Common structural units:

Kugadzirira kweiyo equilibrium reaction:

Shandisa:Shandisa vinyl kune base glue uye organic modification.

Hydroxysilicon mafuta
Tsanangudzo:polysiloxane.
High-molecular-weight synthesis nzira:

Nzira yepasi molecular uremu synthesis:

Commercial hydroxyl silicone mafuta:
107 adhesive:high molecular weight hydroxysilicone oil (viscosity ye1000mPa.s pamusoro), serabha based rubber (kusanganisira phenyl boka re108 adhesive).
Low molecular hydroxyl mafuta:hydroxyl yemukati inopfuura 6%, yakarongeka control agent, fluorinated hydroxyl mafuta ekugadzirisa kudzora kwefluorosilicone rabha.
Rudzi rwemutsara:viscosity 100mPa.s~1000mPa.s, inowanzo shandiswa kugadzira yakagadziridzwa silicone oiri.

Phenyl silicone mafuta

Kushandiswa kwephenyl silicone mafuta:High phenyl yemukati yesilicone mafuta inoshandiswa mukupisa kwakanyanya uye irradiation mamiriro. Yakaderera phenyl yemukati yesilicone oiri yakaderera tembiricha kuita kwakanaka, inoshandiswa kutonhora kuramba zvinodiwa. Iyo refractive rate ye phenyl silicone oiri yakakura kwazvo kubva 1.41 kusvika 1.58, iyo inokodzera maapplication ane refractive rate zvinodiwa.
Special phenyl silicone mafuta:

Polyether silicone mafuta

Muchidimbunemusiyano wekuita we polyether chain segment uye polyether cheni chikamu, kuburikidza nemakemikari bond, hydrophilic polyether cheni chikamu chinopa hydrophilic, polydimethyl siloxane cheni chikamu chinopa kuderera kwepasi tension, uye kuumbwa kwemhando dzese dzebasa repamusoro, kutarisa kwepolethylene silicone mafuta. tsvakiridzo nekusimudzira ndeyekuongorora kwekushandisa, general synthesis nzira, nyore shanduko yechimiro, mune dzidziso inogona kusanganisa isingaperi yakasiyana-siyana yepolyether silicone oiri, kubva pachimiro haigone kunyatsoona kushanda kwayo kwechikumbiro, kuongorora kwekushandisa ndiko kutariswa kwebasa.
Kushandisa polyether silicone mafuta:polyurethane foam foaming agent (L580), coating leveling agent (BYK 3 prefix), surfactant (L-77), machira ekupedzisa agent (softener), mvura-based release agent, antistatic agent, defoaming agent (self-emulsifying type).
