Izimpawu ze-PU

I-polyurethane yokuvala indandatho ibonakala ngokumelana nokugqoka, uwoyela, i-asidi ne-alkali, i-ozone, ukuguga, izinga lokushisa eliphansi, ukudabuka, umthelela, njll. Indandatho yokuvala i-polyurethane inomthwalo omkhulu wokusekela umthamo futhi isetshenziswa kabanzi emikhakheni ehlukahlukene.Ngaphezu kwalokho, indandatho yokuvala insimbi iyamelana nowoyela, imelana ne-hydrolysis, ayigugi, futhi inamandla aphezulu, elungele imishini kawoyela enengcindezi ephezulu, izinto zokuphakamisa, amathuluzi omshini wokubumba, imishini emikhulu ye-hydraulic, njll.

I-polyurethane seal ring: I-polyurethane inezakhiwo ezinhle kakhulu zemishini, futhi ukumelana kwayo nokugqoka kanye nokumelana nokucindezela okuphezulu kuphakeme kakhulu kunamanye amarabha.Ukumelana nokuguga, ukumelana ne-ozone nokumelana nowoyela nakho kuhle impela, kepha kulula ukwenza i-hydrolyze ekushiseni okuphezulu.Ivamise ukusetshenziselwa izixhumanisi zokuvala ezimelana nengcindezi ephezulu nezingagugi, njengamasilinda asebenza ngamanzi.Ngokuvamile, izinga lokushisa ngu-45~90 ℃.

Ngaphezu kokuhlangabezana nezidingo ezijwayelekile zokuvala izindandatho, izindandatho zokuvala ze-polyurethane nazo zizonaka lezi zimo ezilandelayo:

(1) Igcwele ukunwebeka nokukhuthazela;

(2) Amandla emishini afanele, okuhlanganisa amandla okunweba, ubude nokumelana nezinyembezi.

(3) Ukusebenza okuzinzile, okunzima ukuvuvukala phakathi nendawo, kanye nomphumela omncane wokunciphisa ukushisa (umphumela we-Joule).

(4) Kulula ukuyicubungula nokulolongwa, futhi ingagcina usayizi oqondile.

(5) Ayigqwali indawo ethintwayo futhi ingcolise okuphakathi.

I-Ningbo Yokey Automotive Parts Co., Ltd igxile ekuxazululeni izinkinga zezinto zenjoloba zamakhasimende kanye nokuklama ukwakheka kwezinto ezihlukene ngokusekelwe ezimweni ezihlukene zohlelo lokusebenza.
