Iindandatho ze-O zeSilicone
Ukuqonda iRabha yeSilicone
Irabha yesilicone yahlulwe yangamacandelo amabini aphambili: i-gas-phase (ekwaziwa ngokuba yi-high-temperature) silicone kunye ne-condensation (okanye i-room temperature vulcanizing, RTV) silicone. I-gas-phase silicone, edla ngokuthandwa ngenxa yokusebenza kwayo okuphezulu, igcina umbala wayo wokuqala xa yoluliwe, uphawu olubonisa ukongezwa kweekhemikhali ezithile ngexesha lenkqubo yokwenziwa xa kukho i-silicon dioxide (silica). Olu hlobo lwe-silicone lwaziwa ngeempawu zalo zomzimba ezibalaseleyo kunye nokuzinza kumaqondo obushushu aphezulu.
Ngokwahlukileyo koko, i-condensation silicone ijika ibe mhlophe xa yoluliwe, ngenxa yenkqubo yayo yokuvelisa equka ukutshiswa kwe-silicon tetrafluoride emoyeni. Nangona zombini ezi ntlobo zinezicelo zazo, i-gas-phase silicone ngokubanzi ithathwa njengenika ukusebenza okungcono kakhulu kwizicelo zokutywina ngenxa yokuqina kwayo okuphuculweyo kunye nokumelana neemeko ezinzima.
Intshayelelo kwiSilicone O-Rings
Ii-O-Rings zeSilicone zenziwe ngerabha ye-silicone, irabha eyenziweyo exatyiswa kakhulu ngenxa yokuguquguquka kwayo, ukuqina kwayo, kunye nokumelana nobushushu obugqithisileyo. Ezi O-Rings zisetyenziswa kwiindawo ezahlukeneyo apho isitywino esithembekileyo sibalulekile, kwaye zaziwa ngokukwazi kwazo ukumelana neemeko ezinzima ngaphandle kokonakala.
Iimpawu eziphambili zeSilicone O-Rings
Ukumelana nobushushu
Ii-Silicone O-Rings zinokusebenza ngokufanelekileyo kumanqanaba obushushu abanzi, ngesiqhelo ukusuka kwi--70°C ukuya kwi-220°C. Oku kuzenza zilungele zombini ukusetyenziswa kobushushu obuphantsi kunye nobushushu obuphezulu.
Ukumelana neekhemikhali
Nangona ingenakumelana neekhemikhali njenge-PTFE, i-silicone isakwazi ukumelana neekhemikhali ezininzi, kuquka amanzi, iityuwa, kunye nezinye izinyibilikisi ezahlukeneyo. Lukhetho olufanelekileyo kwiindlela ezisetyenziswa ekutyeni, amayeza, kunye nezinye iikhemikhali.
Ukuguquguquka kunye nokuqina
Ukuguquguquka kwe-silicone kunye nokuthamba kwayo kuvumela ii-O-Rings ukuba zigcine uphawu oluqinileyo naphantsi kweemeko ezahlukeneyo zoxinzelelo. Olu phawu luqinisekisa uphawu oluhlala luhleli ubomi bonke be-O-Rings.
Ukumelana nemozulu
I-silicone ayimelani nokukhanya kwe-UV kunye nokutshintsha kwemozulu, nto leyo eyenza ii-O-Rings zilungele ukusetyenziswa ngaphandle kunye neendawo apho ukuchatshazelwa zizinto eziphilayo kuyinto exhalabisayo.
Ayinatyhefu kwaye ivunyiwe yi-FDA
I-silicone ayinabungozi kwaye ihlangabezana nemigangatho ye-FDA yokunxibelelana kokutya, nto leyo eyenza ukuba ibe yinto efanelekileyo yokusetyenziswa kwishishini lokutya neziselo, kunye nezixhobo zonyango.
Ukusetyenziswa kweeSilicone O-Rings
Ishishini leeMoto
IiSilicone O-Rings zisetyenziswa kwiimoto ezifana nezixhobo zenjini, apho zinceda ukugcina izitywino zeoyile kunye namafutha, nakwiinkqubo ze-HVAC.
Ishishini leenqwelo-moya
Kwinqwelo-moya, ii-silicone O-Rings zisetyenziswa kwizitywino zeenjini zeenqwelo-moya nakwezinye iinkqubo ezifuna ukumelana nobushushu obuphezulu kunye nokuguquguquka.
Izixhobo zonyango
Ukuhambelana kwezinto eziphilayo kweSilicone kwenza ukuba ifaneleke ukusetyenziswa kwizixhobo zonyango, kuquka ii-O-Rings zeprosthetics, izixhobo zotyando, kunye nezixhobo zokuxilonga.
Ukulungiswa kokutya neziselo
IiSilicone O-Rings zisetyenziswa kwizixhobo ezidibana nokutya neziselo, ukuqinisekisa ucoceko kunye nokuthintela ungcoliseko.
Izixhobo zombane
Ukumelana kweSilicone nokukhanya kwe-UV kunye nemozulu kwenza ukuba ibe lukhetho olufanelekileyo lokuvala izixhobo ze-elektroniki ezivezwa kwiimeko zangaphandle.
Iingenelo zokusebenzisa ii-Silicone O-Rings
Ukuguquguquka
IiSilicone O-Rings zilungele ukusetyenziswa ngeendlela ezahlukeneyo ngenxa yobushushu bazo kunye nokumelana neekhemikhali.
Ukuqina
Ukuqina kwesi sixhobo kuqinisekisa ubomi benkonzo ende, nto leyo enciphisa isidingo sokutshintshwa rhoqo.
Ukugcinwa Okuphantsi
Ukumelana kwe-silicone kwimozulu eyomileyo kunye nokukhanya kwe-UV kuthetha ukuba ii-O-Rings azidingi ukugcinwa okuncinci.
Isebenza kakuhle emalini
Nangona ii-silicone O-Rings zinokuba nexabiso eliphezulu lokuqala xa kuthelekiswa nezinye izinto, ukuhlala ixesha elide kwazo kunye nokulula kokugcinwa kwazo kunokukhokelela ekongeni iindleko ngokuhamba kwexesha.
