Yintoni i-Methyl Silicone Oli?
Ngokuqhelekileyo, i-methylioli ye-siliconealunambala, alunancasa, alunatyhefu kwaye alunaguquguquki. Ayinyibiliki emanzini, i-methanol okanye i-ethylene glycol. Inokunyibilika kwi-benzene, i-dimethyl ether, i-carbon tetrachloride okanye i-kerosene. Inyibilika kancinane kwi-acetone, i-dioxan, i-ethanol kunye ne-butanol. Ngokuphathelele ioli ye-silicon ye-methyl, ngenxa yokuba i-intermolecular force incinci, i-molecular chain is spiral, kwaye amaqela e-organic angajikeleziswa ngokukhululekileyo, aneempawu ezibalaseleyo zokusasaza ukusebenza, ukuthambisa, ukumelana nobushushu obuphezulu kunye obuphantsi, ukumelana nemozulu, ukumelana nemitha, indawo yokukhanya ephezulu, uxinzelelo olusezantsi kunye ne-physiological inertia, njl njl. Isetyenziswa ngokubanzi kumashishini emihla ngemihla.ikhemikhali, oomatshini, umbane,impahla, ukugquma, amayeza kunye nokutya, njl.
Tyena Iimpawu zeIoli yeMethyl Silicone
Ioli ye-silicone ye-methyl inomsebenzi okhethekileyo.
■ Ukumelana nobushushu okulungileyo
Kwimolekyuli yeoli ye-silicone, ikhonkco eliphambili liqulunqwe yi-Si-O-Si-, enesakhiwo esifanayo kunye ne-polymer ye-inorganic kwaye inamandla amakhulu ebhondi. Ngoko inomsebenzi obalaseleyo wokumelana nobushushu.
■ Ukuxhathisa okulungileyo kwi-oxidation kunye nokumelana nemozulu
■ Ukusebenza kakuhle kokugquma umbane
Ioli ye-Silicone ineempawu ezintle ze-dielectric. Ngokutshintsha kweqondo lokushisa kunye nenombolo yomjikelezo, uphawu lwayo lombane lutshintsha kancinci. I-Dielectric rhoqo iyancipha njengoko iqondo lokushisa linyuka, kodwa utshintsho luncinci kakhulu. Amandla e-oyile ye-silicone aphantsi kwaye ayanda ngokunyuka kweqondo lokushisa, kodwa akukho mithetho yokuphindaphinda. Umthamo wokuxhathisa uyancipha ngokunyuka kobushushu.
■ I-hydrophobicity egqwesileyo
Nangona umxokelelwane oyintloko weoli ye-silicone yenziwe ngebhondi ye-polar, i-Si-O, amaqela e-alkyl angenayo i-polar kwi-chain chain ajoliswe ngaphandle ukuthintela iimolekyuli zamanzi ukuba zingene ngaphakathi kwaye zidlale indima ye-hydrophobic. Uxinzelelo phakathi kobuso phakathi kweoli ye-silicone kunye namanzi malunga ne-42 dynes / cm. Xa usasazwa phezu kweglasi, ngenxa yokugxothwa kwamanzi, ioli ye-silicone inokwenza i-angle yoqhagamshelwano malunga ne-103 °, xa ithelekiswa ne-wax yeparafini.
■ I-viscosity-iqondo lobushushu elincinci lomlinganiso
I-viscosity yeoli ye-silicone iphantsi kwaye itshintsha kancinci ngeqondo lokushisa. Inxulumene nesakhiwo esijikelezayo seemolekyuli zeoli ye-silicone. Ioyile yeSilicone yeyona ineempawu zobushushu be-viscosity phakathi kwazo zonke iintlobo zezithambiso ezingamanzi. Olu phawu lwenza ingqiqo enkulu kwisixhobo sokudambisa.
■ Ukuxhathisa okuphezulu kuxinzelelo
Ngenxa yobume bayo obujikelezayo kunye nomgama omkhulu we-intermolecular, ioli ye-silicone inokumelana noxinzelelo oluphezulu. Ukusebenzisa olu phawu lweoli ye-silicone, inokusetyenziswa njengemithombo yamanzi. Xa kuthelekiswa nentwasahlobo yomatshini, umthamo ungancitshiswa kakhulu.
■ Ukuxinezeleka okuphantsi komphezulu
Uxinzelelo olusezantsi luphawu lweoyile ye-silicone. Ukuxinezeleka okuphantsi komhlaba kubonisa umsebenzi ophezulu. Ke, ioyile ye-silicone inomsebenzi ogqwesileyo wokuthoba ugwebu kunye ne-antifoaming, ukusebenza kodwa kunye nezinye izinto kunye nokusebenza kokuthambisa.
∎ I-nertia engenabungozi, engaguquguqukiyo kunye neyomzimba
Ukusuka kwimbono ye-physiological, i-siloxane polymer yenye yezona zinto zincinci zisebenzayo ezaziwayo. Ioli ye-silicone ye-Dimethyl i-inert kwizinto eziphilayo kwaye ayinayo impendulo yokwenqaba kunye nezilwanyana. Ke isetyenziswe ngokubanzi kwisebe lotyando kunye nesebe lamayeza angaphakathi, amayeza, ukutya kunye nezithambiso, njl.
■ Ukuthambisa okulungileyo
Ioyile yeSilicone ineempawu ezininzi ezigqwesileyo njenge-lubricant, njengendawo ephezulu ye-flash point, indawo yokukhenkceza ephantsi, ukuzinza kwe-thermal, utshintsho oluncinci lwe-viscosity kunye nobushushu, akukho konakala kwentsimbi kwaye akukho mpembelelo imbi kwirabha, iplastiki, ipeyinti kunye nefilimu yepeyinti yendalo, indawo ephantsi. ukuxinezeleka, ukusasazeka lula kumphezulu wesinyithi kunye nokunye. Ukuze kuphuculwe intsimbi kwi-lubricity yensimbi yeoli ye-silicone, izongezelelo zokuthambisa ezinokuxutywa neoli ye-silicone zingongezwa. Iimpawu zokuthambisa zeoli ye-silicone zingaphuculwa kakhulu ngokuzisa iqela le-chlorophenyl kwikhonkco le-siloxan okanye endaweni yeqela le-dimethyl kunye neqela le-trifluoropropyl methyl.
