I-EPDM (Ethylene Propeclene Dieene Monomer) Irabha
Irabha le-EPDMIngabe i-copolymer ye-ethylene, i-propylene kanye nenani elincane le-monomer yesithathu engahlanganisiwe i-diene. Igama lomhlaba wonke ngu: Ethihiene Propyne Diene heteyiene, noma i-EPDM emfushane. I-ePDM Rubber ihle kakhuluUkumelana kwe-UV, ukumelana nesimo sezulu, ukumelana nokuguga, ukumelana kokushisa, ukumelana okuphansi, ukumelana kwama-ozone, ukumelana kwamanzi, ukufakwa kwamanzi, ukufakwa okuhle kukagesi, nezinye izakhiwo ezingokomzimba nezemishini. Lezi zinzuzo azikwazi ukushintshwa ezinye izinto eziningi.
1. Ukumelana Nesimo SezuluInamandla okubekezelela ukubanda okunzima, ukushisa, ukoma kanye nomswakama isikhathi eside, futhi kunomelana kahle nokugqwala kokugqwala ngokuguguleka kweqhwa namanzi, okungangezelela ngokuphelele impilo yenkonzo yeminyango, amawindi kanye nezindonga zekhethini.
2. Ukumelana nokushisa kokuqina kusho ukuthi inokumelana okuqinile kokuguga komoya okushisayo. Ingasetshenziswa ku -40 ~ 120 ℃ isikhathi eside. Futhi kungagcina izici ezisebenzayo isikhathi eside ku-140 ~ 150 ℃. Ingamelana namazinga okushisa aphezulu angama-230 ~ 260 ℃ ngesikhathi esifushane. Ingadlala indima ekuqothulweni kwesakhiwo zasemadolobheni. Ukubambezeleka komphumela; kuhlanganiswe nokusetshenziswa kwefomula ekhethekile,Irabha le-EPDMunomuzwa ofanayo kusuka ku--50 ° C kuya ku-15 ° C. Lokhu kufakwa kwesayithi lokukhiqiza kudale imiphumela esebenza kahle.
3. NgobaI-EPDMInokumelana okuhle kwe-ozone, kwaziwa nangokuthi "irabha elingenama-crack-free". Isetshenziswa ikakhulukazi ezakhiweni ezahlukahlukene zasemadolobheni ngezinkomba ezahlukahlukene zezulu futhi zivezwa ngokuphelele emoyeni. Kuzokhombisa nokuphakama komkhiqizo wayo.
I-4. Ukumelana ne-Ultraviolet Radiation kuhlinzeka ngokuvikelwa kwemvelo kwabasebenzisi bezakhiwo eziphakeme; Ingamelana namandla kagesi angama-60 kuye kwayi-150kv, futhi inokumelana kahle kwe-corona, ukumelana kukagesi, kanye nokumelana kwe-arc. Ukushisa okushisa okuphansi, izinga lokushisa lapho umthamo we-tensile ufinyelela ku-100MPA ngu -58.8 ℃.

1. Ngenxa yezinzuzo zezimpawu ezihlelekile zeI-Silicone Rubber, inamandla okugcina ukuqina okuhle ngaphakathi kwebanga lesikhathi esithile kanye nobubanzi bokushisa obuthile. Uma kuqhathaniswa namanye amakhono okwenziwa, irabha ye-silicone ingamelana namazinga okushisa we-Ultra-101 kuya ku-316 ° C futhi alondoloze izakhiwo zawo zokucindezela.
2. Ezinye izakhiwo ezihlukile zaleli altastomer lendawo yonke:Ukumelana kwemisebe, umthelela omncane we-disinfection umthamo; Ukumelana ne-Vibration, cishe izinga lokudlulisa elihlala njalo kanye nemvamisa ye-resonance ku -50 ~ 65 ° C; Ukuphefumula okungcono kunenye impahla ye-polymers; amandla e-dielectric 500v · km-1; isilinganiso sokuhambisa <0.1-15ωωωωω; kukhulule noma ukugcina ukunamathela; Izinga lokushisa le-Ablation 4982 ° C; ukuqeda okuncane ngemuva kwenhlanganisela efanele; elula yokufaka isicelo ngaphansi kwemithetho yokulawula ukudla ukudla; Izakhiwo ze-Flame retardant; Imikhiqizo engenamibala nongenamphundla ingakhiqizwa; Izakhiwo ezingangeni manzi; Ukuvuselelwa kwe-Physiological kwezindawo ezinhlanu nezifansi zezokwelapha.
3. I-Silicone RubberKungenziwa ngemikhiqizo yemibala ehlukahlukene ngokwezidingo zamakhasimende kanye nezidingo zobuciko.

3. I-TPV / TPE Thermoplastic Elastomer
I-Thermoplastic elastomer inezindawo ezingokomzimba nezemishini zenjoloba evundlekeni kanye nokukhononywa kwamapulasitiki athambile. Kusendaweni ethile phakathi kwepulasitiki nerabha. Ngokuya ngokucutshungulwa, luhlobo lwepulasitiki; Mayelana nezakhiwo, luhlobo lwenjoloba. Ama-elastomers ashisayo anezinzuzo eziningi ngaphezulu kwama-rubber we-thermoset.
1. Ubuningi obuphansi be-thermoplastic elastomer(0.9 ~ 1.1G / CM3), ngaleyo ndlela siyonga izindleko.
2.Ukuguqulwa kwe-compression ephansikanye nokuphikiswa okuhle kokuphefumula.
I-3. Kungahle kube ngokushisayo ukuthuthukisa ukuguquguquka komhlangano nokubekwa uphawu.
I-4. Izinto zokungcola (eziphunyukayo ezifuywayo, izinto zokudonswa kwemfucumfucuza) kanye nemikhiqizo yokugcina imfucuza eyenziwe ngesikhathi sokukhiqiza kungabuyiselwa ngokuqondile ukuze kusetshenziswe kabusha, ukunciphisa ukungcoliswa kwemvelo kanye nokwandisa imithombo yokuphinda usebenzise izinsiza. Kuyinto eluhlaza eluhlaza okotshani nemvelo.
