Tọ Àgwà nkeMethyl silicon mmanụ
Methyl silicone mmanụ nwere ọtụtụ pụrụ iche arụmọrụ.
■ Ezigbo okpomọkụ na-eguzogide
Na molikula mmanụ silicone, isi yinye bụ -Si-O-Si-, nke nwere usoro yiri ya na polymer inorganic ma nwee ike njikọ dị elu.Ya mere, ọ nwere arụmọrụ dị mma nke nguzogide okpomọkụ.
■ Ezigbo nguzogide oxidation na iguzogide ihu igwe
■ Ezigbo ihe mkpuchi ọkụ eletrik
Mmanụ silicone nwere ezigbo dielectric Njirimara.Site na mgbanwe nke okpomọkụ na ọnụọgụ okirikiri, njirimara eletrik ya na-agbanwe ntakịrị.Dielectric mgbe niile na-ebelata ka okpomọkụ na-abawanye, mana mgbanwe ahụ dị ntakịrị.Ihe ike nke mmanụ silicone dị ala ma na-abawanye na okpomọkụ na-ebili, ma ọ dịghị iwu maka ugboro ole.Iguzogide olu na-ebelata na okpomọkụ na-abawanye.
■ Ezigbo hydrophobicity
Ọ bụ ezie na isi yinye mmanụ silicone bụ nke njikọ polar, Si-O, ndị na-abụghị polar alkyl dị n'akụkụ agbụ ahụ na-atụgharị anya n'èzí iji gbochie ụmụ irighiri mmiri ịbanye n'ime ime ma rụọ ọrụ hydrophobic.Esemokwu dị n'etiti ihu dị n'etiti mmanụ silicone na mmiri dị ihe dịka 42 dynes / cm.Mgbe ị na-ekesa n'elu iko, n'ihi mmiri na-asọ oyi ya, mmanụ silicone nwere ike ịmepụta akụkụ kọntaktị nke ihe dịka 103 °, ma e jiri ya tụnyere paraffin wax.
■ Obere ọnụọgụ viscosity-okpomọkụ
Viscosity nke mmanụ silicone dị ala ma ọ na-agbanwe ntakịrị na okpomọkụ.Ejikọtara ya na usoro okirikiri nke mkpụrụ ndụ mmanụ silicone.Mmanụ silicone bụ nke nwere njirimara viscosity-okpomọkụ kacha mma n'etiti ụdị mmanu mmiri niile.Àgwà ọma a na-enwe ezi uche na akụrụngwa damping.
■ Nnukwu iguzogide mkpakọ
N'ihi usoro okirikiri ya na nnukwu anya intermolecular, mmanụ silicone nwere nguzogide mkpakọ dị elu.N'iji njirimara a nke mmanụ silicone, enwere ike iji ya dị ka mmiri mmiri.E jiri ya tụnyere mmiri mmiri na-arụ ọrụ, enwere ike belata ụda olu nke ukwuu.
■ Ala ala esemokwu
Esemokwu dị ala dị ala bụ njirimara mmanụ silicone.Esemokwu dị ala na-egosi ọrụ elu dị elu.N'ihi ya, mmanụ silicone nwere ezigbo defoaming na antifoaming arụmọrụ, ikewapụ ọrụ na ndị ọzọ bekee na lubricating arụmọrụ.
■ Ndị na-adịghị egbu egbu, ndị na-adịghị agbanwe agbanwe na physiological inertia
Site na echiche physiological, siloxane polymer bụ otu n'ime ogige ndị na-arụ ọrụ kacha nta mara.Dimethyl silicone mmanụ bụ inert na ntule na ọ dịghị ajụ mmeghachi omume na ụmụ anụmanụ.Ya mere, etinyere ya n'ọtụtụ ebe na ngalaba ịwa ahụ na ngalaba ọgwụ n'ime ụlọ, ọgwụ, nri na ihe ịchọ mma, wdg.
■ Mma mmanu mmanu
Mmanụ silicone nwere ọtụtụ ihe magburu onwe ya dị ka mmanu mmanu, dị ka ebe ọkụ dị elu, ebe na-ekpo ọkụ dị ala, nkwụsi ike nke okpomọkụ, obere viscosity mgbanwe na okpomọkụ, ọ dịghị corrosion nke ígwè na enweghị mmetụta ọjọọ na roba, plastic, agba na organic paint film, ala ala. esemokwu, dị mfe ịgbasa n'elu igwe na ihe ndị ọzọ.Iji mee ka ígwè ahụ dịkwuo mma na mmanu ọla nke mmanụ silicone, enwere ike ịgbakwunye ihe mgbakwunye na-egbuke egbuke nke nwere ike ịgwakọta ya na mmanụ silicone.Enwere ike imeziwanye ihe mmanu mmanu nke silicone site na iwebata otu chlorophenyl n'ime agbụ siloxan ma ọ bụ dochie otu dimethyl na otu trifluoropropyl methyl.
