I-High Temperature Nylon PPA's Characters and Main Applications

Izici zokusebenza kwe-PPA

I-1, i-PPA iyinto ekwazi ukumelana nezinga lokushisa eliphezulu, enephuzu lokuncibilika phakathi kuka-310-325°C nezinga lokushisa eliphazamisa ukushisa (HDT) phakathi kuka-280-290°C.

I-2, i-PPA inokumelana okuhle kakhulu nowoyela kanye nokumelana okuhle kakhulu nowoyela ohlukahlukene njengamafutha kaphethiloli namafutha okugcoba, ngisho nasezingeni lokushisa eliphakeme lika-150 ℃

I-3, i-PPA inokusimama okuhle kakhulu kwe-dimensional kanye ne-warpage ephansi

4, Izinga lokumuncwa kwamanzi le-PPA liphansi kakhulu kunalelo le-PA6 noma i-PA66, futhi amandla alo aqinile angahlala ngaphezu kwama-80% ngisho nangemva kokucwiliswa emanzini abandayo iminyaka eminingana.

I-5, i-PPA inokumelana nesimo sezulu esihle kakhulu futhi ilungele ukusetshenziswa isikhathi eside ngaphandle ngaphansi kwezimo zezulu ezimbi njengemisebe ye-UV ephezulu, umswakama ophezulu, nokushisa okuphezulu.

6, i-PPA inokusebenza okuhle kakhulu kwezemvelo futhi ingafinyelela ezingeni le-US FDA

Izindawo zokufaka izicelo ze-PPA

Imboni yezimoto:izingxenye zesakhiwo, izindlu ze-thermostat, amaphampu kagesi, izingxenye ze-clutch, amaphampu kawoyela, njll.

Izinkambu zikagesi neze-elekthronikhi:izixhumi, izixhumi ze-SMT, izinqamuli zesekethe, izikhala zamakhadi, njll.

Imboni yemishini:amaphampu amanzi, izesekeli zephampu kawoyela, izixhumi, izifakelo zamapayipi amanzi ashisayo, ama-bearing, amagiya, njll.

Izidingo zansuku zonke:amaphampu amanzi, izesekeli zephampu kawoyela, izixhumi, izifakelo zamapayipi amanzi ashisayo, ama-bearing, amagiya, njll.

Imboni yezimoto

Izinto ze-PPA ezisebenza kahle kakhulu zezimoto zinezakhiwo ezinhle kakhulu ezihlanganisayo. Ukuze uhlangabezane nezidingo zokusetshenziswa kwezingxenye zezimoto, izinto eziqinisiwe ze-PPA zinezindawo ezilandelayo:

Amandla aphezulu, ukuqina okuphezulu

Ukumelana ne-creep enhle kakhulu, amandla okukhathala kanye nokumelana nokudlidliza

Ukuzinza kwe-dimensional okuhle kakhulu

Ukumelana namakhemikhali kumafutha ezimoto, uketshezi kanye namafutha

Ukumelana nokushisa okuphezulu, ukumelana ne-ultrasonic welding;

I-machinability enhle ngokubekezelela isikhunta esiqinile.

I-elekthronikhi nekagesi

Izinto ze-PPA ezisebenza kahle kakhulu zezicelo zikagesi neze-elekthronikhi zinezakhiwo ezinhle kakhulu ezibanzi. Ukuze kuhlangatshezwane nezidingo zezicelo zikagesi neze-elekthronikhi, izinto ze-PPA ezithuthukisiwe zinezindawo ezilandelayo:

Izinga lokushisa lokuhlanekezelwa kokushisa (HDT) ngaphezu kuka-270°C

Ukuzinza kwe-dimensional okuhle kakhulu;

Amandla aphezulu, i-modulus ephezulu, amandla omthelela aphezulu

Ukugeleza okuphezulu kanye nokuncipha okuphansi kokubumba okunembayo

Ukushisa okuphezulu nokumelana ne-solder

I-insulation kagesi enhle kakhulu

Onjiniyela bamakhemikhali

Izinto ze-PPA ezisebenza kahle kakhulu embonini yemishini zinezakhiwo ezinhle kakhulu ezibanzi. Ukuze kuhlangatshezwane nezidingo zokusetshenziswa kwezingxenye zemboni yemishini, izinto eziqinisiwe ze-PPA zinezakhiwo ezilandelayo:

Ukumelana nokushisa okuphezulu, ukushisa okuhlanekezela ukushisa ngaphezu kuka-270 ℃

Ukumelana namakhemikhali

Amandla aphezulu, anti-ukukhathala

Ukuzinza kwe-dimensional okuhle kakhulu

Excellent amanzi ashisayo ukumelana

Ukumelana nowoyela okuhle kakhulu

Izidingo zansuku zonke

Izinto ze-PPA ezisebenza kahle kakhulu zezidingo zansuku zonke zinezakhiwo ezinhle kakhulu ezibanzi. Ukuze kuhlangatshezwane nezidingo zohlelo lokusebenza emkhakheni wezidingo zansuku zonke, izinto eziqinisiwe ze-PPA zinalezi zakhiwo ezilandelayo:

Ukumelana nokushisa okuphezulu

Ukumelana namakhemikhali, ukumelana nokukhathala

Amandla amahle kakhulu nobuqotho bemishini

Ukuzinza kwe-dimensional okuhle kakhulu

I-FDA Iyahambisana
