Amavuta ya Methyl Silicone Niki?
Muri rusange, methylamavuta ya siliconeni ibara, uburyohe, ntabwo ari uburozi kandi budahindagurika.Ntishobora gushonga mumazi, methanol cyangwa Ethylene glycol.Irashobora guhuzwa na benzene, dimethyl ether, karubone tetrachloride cyangwa kerosene.Irashobora gushonga gato muri acetone, dioxan, Ethanol na butanol.Naho amavuta ya methyl silicone, kubera ko imbaraga za intermolecular ari nto, urunigi rwa molekile ni umuzenguruko, kandi amatsinda kama ashobora kuzunguruka ku buntu, afite ibintu byiza cyane byo gukwirakwiza imikorere, amavuta, kurwanya ubushyuhe bwo hejuru no hasi, kurwanya ikirere, kurwanya imirasire, flash flash point, hejuru yubushyuhe buke hamwe nubusembwa bwa physiologique, nibindi bikoreshwa cyane mubikorwa bya buri munsiimiti, imashini, amashanyarazi,imyenda, gutwikira, imiti n'ibiryo, nibindi
Twe IbirangaMethyl Silicone Amavuta
Methyl silicone amavuta afite imikorere idasanzwe.
Resistance Kurwanya ubushyuhe bwiza
Muri molekile ya peteroli ya silicone, urunigi nyamukuru rugizwe na -Si-O-Si-, rufite imiterere isa na polymer organique kandi ifite ingufu nyinshi.Ifite rero imikorere myiza yo kurwanya ubushyuhe.
Resistance Kurwanya okiside nziza no kurwanya ikirere
Performance Imikorere myiza yamashanyarazi
Amavuta ya Silicone afite imiterere myiza ya dielectric.Hamwe nimihindagurikire yubushyuhe numubare wikiziga, amashanyarazi aranga bike.Dielectric ihora igabanuka uko ubushyuhe bwiyongera, ariko impinduka ni nto cyane.Imbaraga zamavuta ya silicone ni make kandi yiyongera hamwe nubushyuhe buzamuka, ariko ntamategeko agenga inshuro.Ijwi ryirwanya rigabanuka hamwe nubushyuhe bwiyongera.
Hyd hydrophobicity nziza
Nubwo urunigi nyamukuru rwamavuta ya silicone rugizwe numubumbe wa polar, Si-O, amatsinda adafite inkingi ya alkyl kumurongo wuruhande yerekeza hanze kugirango abuze molekile zamazi kwinjira imbere kandi zigira uruhare rwa hydrophobique.Impagarara hagati yamavuta ya silicone namazi ni ingoma 42 / cm.Iyo ikwirakwije hejuru yikirahure, kubera amazi yayo, amavuta ya silicone arashobora gukora impande zingana na 103 °, ugereranije nigishashara cya paraffine.
■ Coefficient ya viscosity-ubushyuhe
Ubukonje bwamavuta ya silicone ni make kandi burahinduka gake hamwe nubushyuhe.Bifitanye isano nuburyo buzenguruka bwa molekile ya silicone.Amavuta ya Silicone niyo afite ubwiza-ubushyuhe bwiza buranga ubwoko bwamavuta yose.Ibi biranga byumvikana cyane kubikoresho byo kugabanya.
Resistance Kurwanya cyane kwikuramo
Kubera imiterere ya spiral hamwe nintera nini ya intermolecular, amavuta ya silicone afite imbaraga zo kwihanganira cyane.Ukoresheje ibi biranga amavuta ya silicone, irashobora gukoreshwa nkisoko y'amazi.Ugereranije nisoko yimashini, amajwi arashobora kugabanuka cyane.
Tension Ubushyuhe buke
Ubushyuhe buke bwo hejuru buranga amavuta ya silicone.Ubushyuhe buke bwo hejuru bwerekana ibikorwa byo hejuru.Kubwibyo, amavuta ya silicone afite ibikorwa byiza byo gusebanya no kurwanya antifoaming, imikorere yo kwigunga hamwe nibindi bintu hamwe no gusiga amavuta.
■ Uburozi budafite uburozi, budahindagurika na physiologique
Uhereye kuri physiologique, siloxane polymer nimwe mubintu bidakora bizwi.Amavuta ya Dimethyl silicone yinjizwa mubinyabuzima kandi nta reaction yo kwangwa ninyamaswa.Byakoreshejwe cyane mu ishami ryo kubaga no mu ishami ry'ubuvuzi bw'imbere, ubuvuzi, ibiryo n'amavuta yo kwisiga, n'ibindi.
Ub Amavuta meza
Amavuta ya Silicone afite ibintu byinshi byiza bisiga amavuta, nka flash point yo hejuru, ahantu hakonje cyane, ubushyuhe bwumuriro, ihinduka ryinshi ryubushyuhe hamwe nubushyuhe, nta kwangirika kwicyuma kandi nta ngaruka mbi bigira kuri reberi, plastike, irangi na firime yamabara, hejuru yubutaka impagarara, byoroshye gukwirakwira hejuru yicyuma nibindi.Kugirango tunonosore ibyuma kumavuta ya silicone, amavuta yo kwisiga ashobora kuvangwa namavuta ya silicone arashobora kongerwamo.Amavuta yo gusiga amavuta ya silicone arashobora kunozwa cyane mugutangiza itsinda rya chlorophenyl mumurongo wa siloxan cyangwa gusimbuza dimethyl hamwe na trifluoropropyl methyl groupe.
