I-EPDM gasket abicah gasket
Izinhlobo zeSilicone
Uma uzibuza ukuthi ingabe irabha ye-silicone iyisinqumo esifanele sokuvala, sekuyisikhathi sokubhekisisa lawa ma-elastomer okwenziwa.Okokuqala, sizohlola izinzuzo zokuvala nge-silicone futhi siqhathanise izinto ezithile ze-silicone gasket.Sizobe sesihlukanisa irabha ye-silicone ngezindlela ezahlukene futhi sihlole ezinye izinhlelo zokusebenza.
Ukuxoxa ngesicelo sakho sokuvalwa nge-silicone,sicela usithinte.
Izinzuzo zokuvala uphawu ngeSilicone
Ama-silicone amelana nomswakama, amakhemikhali, ukushisa, amakhaza, i-ozone, nemisebe ye-ultraviolet (UV).Futhi azinzile, aguquguqukayo, ahlala isikhathi eside, futhi ayathandeka ngobuhle.Izinzuzo zenjoloba ye-silicone zihlanganisa:

1. Ukuzinza okuhle kokushisa kanye nokusebenza kabusha kwamakhemikhali aphansi.
2. Ukumelana okuhle kakhulu ne-ozone, ukukhanya kwelanga nomoya-mpilo.
3. Izakhiwo ezingaguquki ekushiseni okuphezulu nokuphansi.
4.Ixosha amanzi, imelana nomswakama, futhi yakha izimpawu ezingangeni manzi.
5. Ukufakwa kahle kukagesi kanye nokungena kahle kwegesi.
6. Woza ngohlu lwama-durometer nemibala yangokwezifiso.
7. Itholakala kumabanga akhethekile kanye nezinto zokugcwalisa.
Izicelo Zokuvala Nge-Silicone Rubber Gaskets
Uma usazibuza ukuthi ingabe ukuvala uphawu nge-silicone kuyisinqumo esifanele, cabanga ngokusetshenziswa kwale polymer ehlukahlukene.Izibonelo ozofunda ngazo akuzona kuphela ukusetshenziswa kwe-silicone, kodwa zimele.
Imishini Ephathwayo
Abakhiqizi bemishini ephathwayo badinga izinto zokuvala nokufaka izinto ezingamelana nezimo ezinzima njengokushisa kwenjini, amazinga okushisa angaphandle adlulele, umoya, amanzi, nodaka.Izibonelo zemikhiqizo ye-silicone yemishini yeselula ihlanganisa izigxivizo ze-shaft, ama-spark plug caps, amapayipi okushisa erediyetha, ama-O-rings, nama-roller gaskets.
Abakhiqizi bemishini ephathwayo nabo badinga amacansi aphansi, izigxivizo zezicabha nezamafasitela, kanye nokufakwa kwe-thermal ne-acoustic.Irabha ye-silicone ayisetshenziselwa zonke lezi zinhlelo zokusebenza, kodwa ukwahlukanisa kwe-injini kungaba ne-fiberglass eboshwe nge-silicone ebheke kanye nongqimba lwegwebu le-silicone yeseli evulekile.Lokhu kugqunywa kwe-thermal-acoustic akukwazi ukumelana nomlilo futhi kumelana namazinga okushisa aqhubekayo afika ku-500° F.
Defense, Aerospace kanye Aviation
Osonkontileka bezokuvikela badinga irabha yokuvala izigxivizo ezimotweni zamasosha nakwezinye izindawo ezinzima kakhulu.Ngezinye izikhathi, ama-silicone wezinga lezempi ayadingeka.Isibonelo, i-MIL-DTL-83528 ichaza izimfuneko zamagaskhi avikelayo e-elastomeric ahlanganisa ukuvalwa kwemvelo nokuvikelwa ekuphazamisekeni kogesi (EMI).
Imboni ye-aerospace nayo idinga ama-silicone gaskets anezakhiwo ezikhethekile.Isibonelo, ama-silicone ahlangabezana nezidingo zokucaciswa kwe-AA-59588A ahlinzeka ngokuqinile kokumelana nokukhathala - isilinganiso sekhono le-elastomer lokumelana nokuguquguquka okuphindaphindiwe noma ukugoba.Ama-silicone ajwayelekile angakwazi ukumelana namazinga okushisa ahlukahlukene, kodwa akuwona wonke ama-silicone amelana namazinga aphezulu okukhathala.
Izinsiza Zokudla
Abakhiqizi bezinto zokudla badinga irabha ekwazi ukumelana nokushisa okuphezulu okuvela kohhavini bezentengiselwano kanye namazinga okushisa abandayo avela eziqandisini naseziqandisini.Ama-Silicone aphatha lawa mazinga okushisa adlulele futhi angamelana nokuhlanzwa okuvamile okudingekayo ngokudla nempahla yesiphuzo.Kusukela kumata okubhaka kuya kuma-oven seals, irabha ye-silicone iphinde imelane nama-grease namafutha.
Ngokuya ngesicelo, abakhiqizi bensimbi engagqwali kanye nempahla yokudla bangadinga ukusebenzisa izinto ze-silicone ezigunyazwe yi-FDA.Ama-silicone e-FDA awawona ubuthi, awamaki, futhi awawona ama-allergenic.Futhi ayinambitheki, ayinaphunga, futhi imelana nokukhula kwemvelo kwamagciwane.Akuwona wonke ama-silicones ebanga lokudla avunyelwe yi-FDA, noma kunjalo.
Ezivalekile kanye Nokwakha kanye Nokwakha
Ukuvalwa kwe-Enclosure ngama-flurosilicons kusetshenziswa imishini yamathebulethi embonini yezemithi.Ama-silicones nawo asetshenziswa ezindaweni ezivalekile zemishini kagesi nekagesi.Ezakhiweni, irabha ye-silicone ingasetshenziswa ezimpawu zefasitela nezimpawu zeminyango.Ngezinye izinhlobo zezakhiwo ezakhiwe, ama-silicone asetshenziselwa ukunwetshwa kwamalunga ngoba lawa ma-elastomers avumela ukwanda okushisayo ngaphandle kokuhlanekezela.
Ngezakhiwo zawo eziqinile ze-dielectric, ama-silicone asetshenziswa nezintambo nokunqanyulwa kwekhebula, amashubhu okufakwayo angamelana ne-corona, amakhibhodi, nomata bokuxhumana.Ama-silicone agcwele izinhlayiyana ahlinzeka ngokuvikela kwe-EMI asetshenziswa ezimpahleni eziguquguqukayo ngoba izinhlayiya zensimbi noma ezimbozwe ngensimbi nazo zinikeza ukuqhutshwa kukagesi.Ama-silicone angu-UL 94 amelana nokusabalala komlilo asetshenziswa kuma-gasket enjoloba ezindaweni ezivalekile zikagesi.
Ukunakekelwa Kwezempilo Nezempilo
Ama-Silicone wezinhlelo zokusebenza zezokwelapha nezokunakekelwa kwezempilo asetshenziswa kushubhu kumishini yezokwelapha kanye nemishini, imibhobho yama-respirators okwenziwa, namagasket e-EMI.Njengempahla yokudla nesiphuzo, irabha egunyazwe yi-FDA ingadingeka.Nokho akuwona wonke ama-silicone ezindawo zokunakekelwa kwempilo adinga ukugunyazwa kwe-FDA.Izibonelo zifaka izivalo zeminyango ye-silicone kubhavu abangena kuwo ezigulini zasesibhedlela.
Ama-Silicone nawo asetshenziswa nezibambo zokuphakamisa isiguli.Ishubhu lensimbi lingathwala isisindo sesiguli, kodwa insimbi engagqwali iyabanda, iqinile, futhi ngezinye izikhathi iyashelela.Izibambo ze-silicone ze-slip-on zisekela ukubamba okulula ukuze kuphephe nokunethezeka kwesiguli.
