Umsesane wokutywina we-Silicone luhlobo lomsesane wokutywina.Yenziwe ngejeli ye-silica eyahlukeneyo kwaye isetyenziselwa ukulungisa ikhava ye-annular ukuze ikwazi ukufanisa isithuba phakathi kwe-ferrule okanye i-gasket kwi-bearing.Ihluke kumsesane wokutywina owenziwe ngezinye izinto.Ukusebenza kokumelana namanzi okanye ukuvuza kungcono ngakumbi.Okwangoku, isetyenziselwa ikakhulu ukutywinwa kwamanzi kunye nokugcinwa kwezinto eziyimfuneko zemihla ngemihla ezifana ne-crisper, i-rice cooker, i-dispenser yamanzi, ibhokisi lesidlo sasemini, ikomityi enemagnethi, imbiza yekofu, njl. ethandwa ngumntu wonke.Ke namhlanje, makhe sijonge nzulu umsesane wokutywina we-silicone.
Umahluko phakathi kweringi yokutywina ye-silicone kunye nezinye ikhonkco lokutywina:
1. Ukumelana nemozulu okugqwesileyo
Ukumelana nemozulu kubhekiselele kuthotho lweziganeko zokwaluphala ezifana nokufiphala, ukujika kombala, ukuqhekeka, ukutshotsholwa kunye nokuncipha kwamandla ngenxa yempembelelo yeemeko zangaphandle ezifana nokukhanya kwelanga ngqo kunye nokutshintsha kobushushu.Imitha ye-ultraviolet iyona nto iphambili ekhuthaza ukuguga kwemveliso.Ibhondi ye-Si-O-Si kwirabha ye-silicone izinzile kakhulu kwi-oksijini, i-ozone kunye nemitha ye-ultraviolet, kwaye inokumelana okuhle kakhulu nokhukuliseko lwe-ozone kunye nee-oxides.Ngaphandle kwazo naziphi na izongezo, inokumelana nemozulu entle kakhulu, nokuba isetyenziswe ngaphandle ixesha elide, ayiyi kuqhekeka.
2. Ukhuseleko lwezinto eziphathekayo kunye nokukhuselwa kwendalo
Irabha ye-Silicone ine-inertness yayo ekhethekileyo ye-physiological, engeyiyo ityhefu kwaye ayinancasa, ayinamthubi kwaye ayifihli emva kokusetyenziswa kwexesha elide, kwaye ayiphazanyiswa kangako yimeko yangaphandle.Ihlangabezana nemigangatho yokutya yelizwe kunye nococeko lwezonyango.Isetyenziswa kakhulu ekutyeni, amayeza, aluminiyam isilivere intlama kunye neeoli ezahlukeneyo.ukungcola kwesihluzi sodidi sivuliwe.
3. Ukusebenza kakuhle kokufakelwa kombane
I-silicone ye-silicone ineempawu ezigqwesileyo zokugquma umbane, kwaye ilungile kakhulu ekuxhathiseni kwe-corona (ikhono lokuchasa ukuthotywa komgangatho) kunye nokumelana ne-arc (amandla okuxhathisa ukuwohloka okubangelwa yi-high-voltage arc action).
4. Ukungena komoya ophezulu kunye nokukhetha ukuhanjiswa kwegesi
Ngenxa yesakhiwo semolekyuli ye-silica gel, i-silica gel yokutywina iringi inokungena kakuhle kwegesi kunye nokukhetha okulungileyo kwiigesi.Kwiqondo lokushisa, i-gas permeability yerabha ye-silicone emoyeni, i-nitrogen, i-oksijini, i-carbon dioxide kunye nezinye iigesi ziphindwe ngama-30-50 ngaphezu kwerabha yendalo.amaxesha.
5. Hygroscopicity
Amandla angaphezulu kwendandatho ye-silicone iphantsi, inomsebenzi wokufunxa kunye nokukhusela umswakama kwindawo.
6. Uluhlu olubanzi lokumelana nokushisa okuphezulu kunye nokuphantsi
(1).Ukumelana nobushushu obuphezulu:Xa kuthelekiswa nerubha eqhelekileyo, ikhonkco lokutywina elenziwe nge-silica gel inokumelana nobushushu obungcono, kwaye inokufudumeza kwiqondo lokushisa eliphezulu ngaphandle kokuguqulwa kwaye ngaphandle kokuvelisa izinto ezinobungozi.Ingasetyenziselwa phantse ngonaphakade kwi-150 ° C ngaphandle kokutshintsha ukusebenza, ingasetyenziselwa ngokuqhubekayo kwi-200 ° C kwiiyure ze-10,000, kwaye ingasetyenziselwa kwi-350 ° C ixesha elithile.Isetyenziswa kakhulu kwiimeko ezifuna ukumelana nobushushu, njenge: ibhotile ye-thermos yokutywina iringi.
(2).Ukumelana nobushushu obuphantsi:Irabha eqhelekileyo iya kuba lukhuni kwaye ibe brittle ku -20°C ukuya ku -30°C, lo gama irabha yesilicone isenokwaleka okulungileyo ku -60°C ukuya ku -70°C.Enye irabha yesilicone eyenziwe ngokukodwa Iyakwazi ukumelana namaqondo obushushu aphantsi kakhulu, afana nala: iiringi zokutywina ze-cryogenic, eyona iphantsi inokufikelela kwi -100°C.
Ukungalungi kwamatywina erabha ye-silicone:
(1).Iimpawu zomatshini zamandla okuqina kunye namandla okukrazula zimbi.Akukhuthazwa ukusebenzisa iindandatho zokutywina ze-silicone zokwelula, ukukrazula, kunye nokunxiba okunamandla kwindawo yokusebenza.Ngokuqhelekileyo, isetyenziselwa kuphela ukutywinwa okumileyo.
(2).Nangona irabha ye-silicone ihambelana neoli eninzi, iikhompawundi kunye nezinyibilikisi, kwaye ine-asidi efanelekileyo kunye nokumelana ne-alkali, ayinakumelana ne-alkyl hydrogen kunye neoli enuka kamnandi.Ngoko ke, ayifanelekanga ukusetyenziswa kwiindawo apho uxinzelelo olusebenzayo ludlula iipounds ezingama-50.Ukongezelela, akukhuthazwa ukusebenzisa izitywina ze-silicone kwii-solvents ezininzi ezigxininisiweyo, i-oyile, i-acids egxininisiweyo kunye ne-diluted caustic soda solutions.
(3).Ngokwexabiso, xa kuthelekiswa nezinye izinto, iindleko zokwenziwa kwe-silicone yokutywina iringi yerabha iphezulu.
