Izici ze-Methyl Silicone Amafutha

Iyini I-Methyl Silicone Amafutha?

Ngokuvamile, i-methylamafutha abicahuketshezi olungenambala, alunambitheki, olungenabuthi futhi olungaguquguquki.Ayincibiliki emanzini, i-methanol noma i-ethylene glycol.Ingahlanganiswa ne-benzene, i-dimethyl ether, i-carbon tetrachloride noma uphalafini.Incibilika kancane ku-acetone, i-dioxan, i-ethanol ne-butanol.Ngokuqondene nowoyela we-methyl abicah, ngoba amandla e-intermolecular mancane, uchungechunge lwamangqamuzana luyi-spiral, futhi amaqembu e-organic angashintshwa ngokukhululekile, anezici ezinhle kakhulu zokusabalalisa ukusebenza, ukugcoba, ukumelana nokushisa okuphezulu nokuphansi, ukumelana nesimo sezulu, ukumelana nemisebe, indawo ekhanyayo ephezulu, ukushuba kwesimo esiphansi kanye ne-inertia yokuphila, njll. Isetshenziswa kabanzi ezimbonini zansuku zonke.amakhemikhali, imishini, ugesi,izindwangu, ukugqoka, umuthi nokudla, njll.

Amakhemikhali

Tyena Izici zeAmafutha e-Methyl Silicone

Uwoyela we-silicone we-methyl unokusebenza okukhethekile kakhulu.

■ Ukumelana nokushisa okuhle

Kumolekyuli kawoyela we-silicone, iketango eliyinhloko lakhiwa -Si-O-Si-, elinesakhiwo esifanayo ne-polymer ye-inorganic futhi enamandla amakhulu ebhondi.Ngakho inokusebenza okuhle kakhulu kokumelana nokushisa.

■ Ukumelana kahle ne-oxidation kanye nokumelana nesimo sezulu

■ Ukusebenza kahle kwe-insulating kagesi

Amafutha e-Silicone anezakhiwo ezinhle kakhulu ze-dielectric.Ngokushintsha kwezinga lokushisa nenombolo yomjikelezo, isici sayo sikagesi sishintsha kancane.I-Dielectric njalo iyancipha njengoba izinga lokushisa likhuphuka, kodwa ushintsho luncane kakhulu.Isici samandla samafutha we-silicone siphansi futhi sikhuphuka ngokukhuphuka kwezinga lokushisa, kodwa ayikho imithetho yemvamisa.Ukumelana nevolumu kuyehla ngokukhuphuka kwezinga lokushisa.

■ I-hydrophobicity enhle kakhulu

Nakuba iketango eliyinhloko lamafutha abicah lakhiwe ngebhondi ye-polar, i-Si-O, amaqembu e-alkyl angeyona i-polar ochungechungeni oluseceleni aqondiswe ngaphandle ukuze avimbele ama-molecule amanzi ukuthi angangeni ngaphakathi futhi adlale indima ye-hydrophobic.Ukungezwani phakathi kobuso phakathi kukawoyela we-silicone namanzi cishe kungama-dynes angama-42/cm.Uma usakazwa phezu kwengilazi, ngenxa yokuxosha amanzi, uwoyela we-silicone ungenza i-engeli yokuthintana engaba ngu-103°, uma kuqhathaniswa nengcina kapharafini.

■ I-coefficient encane ye-viscosity-temperature

I-viscosity kawoyela we-silicone iphansi futhi ishintsha kancane ngokushisa.Ihlobene nesakhiwo esivunguzayo sama-molecule kawoyela we-silicone.Amafutha e-Silicone yiwo anesici esihle kakhulu se-viscosity-temperature phakathi kwazo zonke izinhlobo zezinto zokuthambisa eziwuketshezi.Lesi sici senza umqondo omkhulu kumishini yokudambisa.

■ Ukumelana okuphezulu nokucindezela

Ngenxa yesakhiwo sawo esivunguzayo kanye nebanga elikhulu le-intermolecular, uwoyela we-silicone unokumelana nokucindezelwa okuphezulu.Ukusebenzisa lesi sici samafutha we-silicone, singasetshenziswa njengemithombo yamanzi.Uma kuqhathaniswa nentwasahlobo yemishini, ivolumu ingancishiswa kakhulu.

■ Ukungezwani okuphansi kwendawo

I-low surface tension yisici samafutha abicah.I-low surface tension ikhombisa umsebenzi ophezulu.Ngakho-ke, uwoyela we-silicone unomsebenzi omuhle kakhulu wokuqeda ugwebu kanye nokusebenza kwe-antifoaming, ukusebenza kokuzihlukanisa nezinye izinto kanye nokusebenza kokugcoba.

Amafutha e-Silicone

∎ I-inertia engenabuthi, engaguquguquki kanye neyokuphila

Ngokombono wokuphila, i-siloxane polymer ingenye yezinhlanganisela ezisebenza kancane kakhulu ezaziwayo.Amafutha e-dimethyl abicah ayisebenzi ezintweni eziphilayo futhi ayinakho ukusabela okwenqaba nezilwane.Ngakho-ke isetshenziswe kabanzi emnyangweni wokuhlinza kanye nomnyango wemithi yangaphakathi, imithi, ukudla nezimonyo, njll.

■ Ukuthambisa okuhle

Amafutha e-Silicone anezakhiwo eziningi ezinhle kakhulu njengesithako sokuthambisa, njengephuzu eliphakeme elikhanyayo, indawo ebandayo ephansi, ukuzinza okushisayo, ukuguquka kwe-viscosity encane ngezinga lokushisa, akukho ukugqwala kwensimbi futhi akukho thonya elibi enjolobeni, ipulasitiki, upende kanye nefilimu kapende we-organic, indawo ephansi. ukungezwani, ukusabalalisa kalula endaweni yensimbi nokunye.Ukuze kuthuthukiswe insimbi ku-lubricity yensimbi kawoyela we-silicone, izithasiselo zokugcoba ezingaxutshwa namafutha abicah zinganezelwa.Izakhiwo zokugcoba zamafutha we-silicone zingathuthukiswa kakhulu ngokwethula iqembu le-chlorophenyl eketheni le-siloxan noma esikhundleni seqembu le-dimethyl ngeqembu le-trifluoropropyl methyl.
