I-Silicone sealing ring iwuhlobo lwendandatho yokuvala.Yenziwe ngejeli ye-silica ehlukahlukene futhi isetshenziselwa ukulungisa ikhava ye-annular ukuze ikwazi ukufanisa igebe phakathi kwe-ferrule noma i-gasket ekuthwaleni.Ihlukile kunendandatho yokuvala eyenziwe ngezinye izinto.Ukusebenza kokumelana namanzi noma ukuvuza kungcono nakakhulu.Njengamanje, isetshenziselwa kakhulu ukuvala amanzi kanye nokugcinwa kwezidingo zansuku zonke ezifana ne-crisper, i-rice cooker, i-water dispenser, ibhokisi lesidlo sasemini, inkomishi enozibuthe, ibhodwe lekhofi, njll. Kulula ukuyisebenzisa, iphephile futhi ihambisana nemvelo, futhi ijulile. ethandwa yiwo wonke umuntu.Ngakho-ke namuhla, ake sibheke ngokujulile iringi yokuvala i-silicone.
Umehluko phakathi kwendandatho yokuvala i-silicone nezinye izindandatho zokuvala:
1. Ukumelana nesimo sezulu esihle kakhulu
Ukumelana nesimo sezulu kubhekisela ochungechungeni lwezigigaba zokuguga ezinjengokufiphala, ukushintsha umbala, ukuqhekeka, ukushotsholwa nokuphelelwa amandla ngenxa yethonya lezimo zangaphandle ezifana nokukhanya kwelanga okuqondile kanye nokushintsha kwezinga lokushisa.Imisebe ye-Ultraviolet iyisici esiyinhloko esikhuthaza ukuguga komkhiqizo.Ibhondi ye-Si-O-Si kurabha ye-silicone izinze kakhulu kumoya-mpilo, i-ozone kanye nemisebe ye-ultraviolet, futhi inokumelana okuhle kakhulu nokuguguleka kwe-ozone nama-oxides.Ngaphandle kwanoma yiziphi izithasiselo, inokumelana nesimo sezulu esihle kakhulu, noma ngabe isetshenziswa ngaphandle isikhathi eside, ngeke iqhekeke.
2. Ukuphepha kwezinto ezibonakalayo kanye nokuvikelwa kwemvelo
Irabha ye-Silicone inomzimba wayo oyingqayizivele ongenabuthi, ongenabuthi futhi awunambitheki, awuphuzi futhi awufihli ngemva kokusetshenziswa isikhathi eside, futhi ayiphazanyiswa kancane indawo yangaphandle.Ihlangabezana nezindinganiso zikazwelonke zokudla kanye nenhlanzeko yezokwelapha.Isetshenziswa kakhulu ekudleni, emithini, ekunamathiseleni kwesiliva kwe-aluminium kanye namafutha ahlukahlukene.ukungcola kwesihlungi sekilasi kuvuliwe.
3. Ukusebenza kahle kokufakwa kukagesi
I-silicone ye-silicone inezinto ezinhle kakhulu zokufaka ugesi kagesi, futhi inhle kakhulu ekuphikisweni kwe-corona (ikhono lokumelana nokuwohloka kwekhwalithi) kanye nokumelana ne-arc (ikhono lokumelana nokuwohloka okubangelwa isenzo se-arc enamandla kagesi).
4. Ukungena komoya okuphezulu kanye nokukhetha ekudluliselweni kwegesi
Ngenxa yesakhiwo samangqamuzana ejeli ye-silica, indandatho yokuvala ijeli ye-silica inokungena kahle kwegesi nokukhetha okuhle kumagesi.Emazingeni okushisa asekamelweni, ukungena kwegesi kwenjoloba ye-silicone emoyeni, i-nitrogen, i-oxygen, i-carbon dioxide namanye amagesi kuphindwe izikhathi ezingu-30-50 kunaleyo yenjoloba yemvelo.izikhathi.
5. Hygroscopicity
Amandla angaphezulu kwendandatho ye-silicone aphansi, anomsebenzi wokumunca nokufaka umswakama endaweni.
6. Uhlu olubanzi lokumelana nokushisa okuphezulu nokuphansi
(1).Ukumelana nezinga lokushisa eliphezulu:Uma kuqhathaniswa nerabha evamile, indandatho yokuvala eyenziwe ngejeli ye-silica inokumelana nokushisa okungcono, futhi ingashiswa ekushiseni okuphezulu ngaphandle kokuguqulwa futhi ngaphandle kokukhiqiza izinto eziyingozi.Ingasetshenziswa cishe unomphela ku-150°C ngaphandle kokushintsha kokusebenza, ingasetshenziswa ngokuqhubekayo ku-200°C amahora angu-10,000, futhi ingasetshenziswa ku-350°C isikhathi esithile.Isetshenziswa kakhulu ezikhathini ezidinga ukumelana nokushisa, njengalokhu: indandatho yokuvala ibhodlela le-thermos.
(2).Ukumelana nezinga lokushisa eliphansi:Irabha evamile izoba lukhuni futhi ibe brittle ku -20°C kuya ku-30°C, kuyilapho irabha ye-silicone isenokunwebeka okuhle kokuthi -60°C kuya ku-70°C.Enye irabha ye-silicone eyakhiwe ngokukhethekile Ingakwazi futhi ukumelana namazinga okushisa aphansi kakhulu, njengalezi: izindandatho zokuvala i-cryogenic, eziphansi kakhulu zingafinyelela -100°C.
Ububi bezimpawu zenjoloba ye-silicone:
(1).Izakhiwo zemishini zamandla aqinile namandla okudabula zimbi.Akunconywa ukusebenzisa izindandatho zokuvala i-silicone ukuze zilule, ziklebhule, futhi zigqoke ngokuqinile endaweni yokusebenza.Ngokuvamile, isetshenziselwa ukubekwa uphawu okumile kuphela.
(2).Nakuba irabha ye-silicone ihambisana namafutha amaningi, izinhlanganisela nezinyibilikisi, futhi ine-asidi enhle ne-alkali ukumelana, ayinakho ukumelana ne-alkyl hydrogen namafutha anephunga elimnandi.Ngakho-ke, akufanelekile ukusetshenziswa ezindaweni lapho ingcindezi yokusebenza idlula amakhilogremu angu-50.Ngaphezu kwalokho, akunconywa ukusebenzisa izimpawu ze-silicone kuma-solvents amaningi, amafutha, ama-acids agxilile kanye nezixazululo ze-caustic soda ezihlanjululwe.
(3).Ngokwenani, uma kuqhathaniswa nezinye izinto, izindleko zokukhiqiza indandatho yenjoloba yokuvala i-silicone iphakeme kakhulu.
