I-Silicone tube iwuhlobo lwerabha enezakhiwo ezibanzi nezinhle ezibanzi.Inokusebenza okuhle kakhulu kokufakwa kukagesi, ukumelana nokuguga, ukuzinza kwamakhemikhali, ukumelana ne-oxidation kanye nokumelana nesimo sezulu, ukumelana nemisebe, inertia ye-physiological, ukungena komoya okuhle, nokumelana nokushisa okuphezulu nokuphansi.Ingasetshenziswa ku -60℃～250℃ ukuze isetshenziswe isikhathi eside.Ngakho-ke, isetshenziswa kabanzi kwezokundiza, i-electronics, i-petroleum, imboni yamakhemikhali, imishini, izinto zikagesi, ezokwelashwa, i-oven, ukudla nezinye izimboni zesimanje, imboni yezokuvikela kanye nezidingo zansuku zonke.
Ishubhu ye-silicone yenziwe ngerabha yerabha eluhlaza ye-silicone engezwe kumxube werabha ogingqika kabili noma i-kneader engangenisi umoya, futhi izithasiselo ezimnyama ezimhlophe nezinye zengezwa kancane kancane ukuze zicwengwe ngokuphindaphindiwe nangokulinganayo.Ngokusho kwamazinga obuchwepheshe embonini, umkhiqizo wenziwa nge-extrusion.
Ukwahlukanisa
Amashubhu a-silicone ajwayelekile yilawa: ishubhu ye-silicone yezokwelapha, ishubhu ye-silicone yebanga lokudla, ishubhu ye-silicone yezimboni, ishubhu elimise okwe-silicone elikhethekile, izesekeli zeshubhu ye-silicone.
Amashubhu e-silicone yezokwelapha asetshenziselwa ikakhulukazi izesekeli zedivayisi yezokwelapha, ama-catheter ezokwelapha, futhi amukele ukwakheka kwe-antibacterial ukuqinisekisa ukusetshenziswa okuphephile.
Amashubhu e-silicone ebanga lokudla asetshenziselwa iziphakeli zamanzi, amapayipi okuphambukisa umshini wekhofi, kanye nokuvikelwa kolayini ongangeni manzi ezintweni zasendlini.
Amashubhu e-silicone yezimboni asetshenziselwa ukusakazwa kwamakhemikhali akhethekile, ugesi nokunye okukhethekile okuthwala ukuvikela imvelo, kusetshenziswa i-silicone yokusebenza okukhethekile.
izici zobuchwepheshe
1. Ukuqina: 70±5, amandla aqinile: ≥6.5.
2. Umbala womkhiqizo: obala, omhlophe, omnyama, obomvu, ophuzi, oluhlaza okotshani (ungakhiqizwa futhi ngesicelo).
3. Ibanga lokumelana nezinga lokushisa: -40–300℃.
4. Usayizi: caliber 0.5—30MM.
5. Izakhiwo ezingaphezulu: Hlanganisa amanzi, anganamathele ezintweni eziningi, futhi angadlala indima yokuba yedwa.
6. Izakhiwo zikagesi: Uma zichayeka kumswakama noma amanzi noma izinga lokushisa likhuphuka, ushintsho luncane, ngisho noma luvutha kumjikelezo omfushane.
7. I-silicon dioxide ekhiqiziwe iseyi-insulator, eqinisekisa ukuthi izinto zikagesi ziyaqhubeka nokusebenza, ngakho-ke ifaneleka kakhulu ekwenzeni izintambo, izintambo, nezintambo zokuhola.
izici zokusebenza
①Ibanga lokushisa eliqhubekayo lokusetshenziswa: -60℃~200℃;
②Ithambile, imelana ne-arc futhi imelana ne-corona;
③ Ukucaciswa okuhlukahlukene kungenziwa ngezifiso ngokuya ngezidingo zekhasimende.
④Ayinabungozi, ayinabungozi futhi ayinambitheki
⑤Ukumelana nengcindezi ephezulu, ukuvikelwa kwemvelo
Izici
Irabha ye-Silicone iwuhlobo olusha lwezinto ezinwebekayo ze-polymer, ezinokumelana okuhle kakhulu nokushisa okuphezulu (250-300 ° C) nokumelana nokushisa okuphansi (-40-60 ° C), ukuzinza okuhle komzimba, futhi ingakwazi ukumelana nezimo ezinzima eziphindaphindiwe.Futhi izimo zokubulala amagciwane, ezinokuqina okuhle kakhulu kanye nokuguqulwa okuncane okungapheli (200 ℃ amahora angu-48 ngaphansi kuka-50%), i-voltage yokuwohloka (20-25KV/mm), ukumelana ne-ozone, ukumelana ne-UV.Ukumelana nemisebe nezinye izici, irabha ekhethekile ye-silicone inokumelana nowoyela.
isicelo
1. Ezokuthutha: ezisetshenziswa embonini yokwakha imikhumbi.
2. Umsakazo kanye nezinjini: embonini yezokuxhumana.
3. Kusetshenziswa embonini yezinsimbi nezinsimbi.
4. Isicelo embonini yezokundiza.
5. Ifanele izinto zikagesi zasendlini, ukukhanyisa, ukwelashwa, ubuhle nemishini yokulungisa izinwele, njll.
Umehluko ngepayipi le-PVC
Ishubhu le-silicone nalo liwuhlobo lweshubhu lerabha, elikwazi ukumelana nowoyela futhi likwazi ukumelana nokushisa.Amashubhu enjoloba anezicelo eziningi ngenxa yezinhlobo ezahlukene zenjoloba.Izinto ezisetshenziswa kakhulu zamashubhu enjoloba zifaka i-EPDM, i-CR, i-VMQ, i-FKM, i-IIR, i-ACM, i-AEM, njll. Izakhiwo ezivamile zihlanganisa ungqimba olulodwa, ungqimba oluphindwe kabili, ungqimba oluningi, nokuqinisiwe, okungathuthukisiwe, njll.
Okokuqala, ijeli ye-silica ingeyezinto zenjoloba, i-PVC ingeyepulasitiki, impahla eyinhloko yepayipi le-PVC yi-polyvinyl chloride, kanti into eyinhloko yepayipi ye-silicone i-silicon dioxide.
1. Ipayipi le-PVC lenziwe nge-polyvinyl chloride resin, stabilizer, lubricant, njll., bese likhishwa ngomshini wokubumba umjovo oshisayo.Ukusebenza okuyinhloko, ukwahlukanisa ugesi;ukuzinza okuhle kwamakhemikhali;ukuzicisha;ukumuncwa kwamanzi aphansi;kulula ukunamathela Connection, ungakwazi ukumelana lokushisa eliphezulu mayelana 40 °.Imishini eyinhloko igesi yasezimbonini, izinto zokuhamba eziwuketshezi, njll., amapayipi endle, amapayipi amanzi, njll. Izinkinga zokuvikela imvelo: Izinto eziyinhloko ezisizayo ezifana nama-plasticizer kanye nama-anti-aging agents anezelwe anobuthi.Amapulasitiki kumapulasitiki e-PVC asetshenziswa nsuku zonke ikakhulukazi asebenzisa i-dibutyl terephthalate, i-dioctyl phthalate, njll. Lawa makhemikhali Imikhiqizo inobuthi.
2. Amashubhu e-silicone, impahla ye-silicone inamakhemikhali azinzile, ayiphenduli nanoma yiziphi izinto zamakhemikhali ngaphandle kwe-alkali eqinile ne-hydrofluoric acid, inamakhemikhali amahle, ukusebenza kahle kokufakwa kukagesi, akulula ukuguga nesimo sezulu, izinto ezithambile, ezinobungani bemvelo. kanye nezinto ezingezona ezinobuthi, Ezingenambala futhi azinaphunga.Amapayipi asekhaya azokwenziwa ngezinto ze-silicone, ezisetshenziswa kakhulu ezintweni zasendlini, imboni yezokwelapha, imboni yezimboni, imboni yezimoto nokunye.
Isici esikhulu kunazo zonke se-silicone hose ukuthi imelana nezinguquko zokushisa kusuka ku--60 degrees kuya ku-250 degrees, kodwa izindleko zibiza kakhulu.I-PVC ivame ukusetshenziswa njengamapayipi amanzi ajwayelekile, azwela ukushisa, eshibhile futhi enuka, afanele izindawo zokusebenza ezijwayelekile, futhi angenazo izidingo zamapayipi.Amashubhu a-silicone amelana nengcindezi, kodwa i-PVC iyisilinganiso, kuye ngokuqina kodonga kanye nekharibha.Lona umehluko phakathi kwamashubhu e-silicone namashubhu e-PVC.
