Indandatho yokuvala ye-polyurethane ibonakala ngokumelana nokuguguleka, uwoyela, i-asidi kanye ne-alkali, i-ozone, ukuguga, izinga lokushisa eliphansi, ukudabuka, umthelela, njll. Indandatho yokuvala ye-polyurethane inomthamo omkhulu wokusekela umthwalo futhi isetshenziswa kabanzi emikhakheni eyahlukahlukene. Ngaphezu kwalokho, indandatho yokuvala ehlanganisiwe ayimelani namafutha, ayimelani ne-hydrolysis, ayigugi, futhi inamandla aphezulu, afanele imishini kawoyela enomfutho ophezulu, imishini yokuphakamisa, amathuluzi omshini wokubumba, imishini emikhulu ye-hydraulic, njll.
Indandatho yokuvala ye-polyurethane: i-polyurethane inezakhiwo ezinhle kakhulu zemishini, futhi ukumelana kwayo nokuguguleka kanye nokumelana nokucindezela okuphezulu kuphakeme kakhulu kunezinye irabha. Ukumelana nokuguga, ukumelana ne-ozone kanye nokumelana nowoyela nakho kuhle impela, kodwa kulula ukuyi-hydrolyze ekushiseni okuphezulu. Ngokuvamile isetshenziselwa izixhumanisi zokuvala ezingaguguleki kanye nezingagugi, njengezilinda ze-hydraulic. Ngokuvamile, izinga lokushisa lingu-45~90 ℃.
Ngaphezu kokuhlangabezana nezidingo ezijwayelekile zezinto zokubopha indandatho, izindandatho zokubopha ze-polyurethane kufanele futhi ziqaphele lezi zimo ezilandelayo:
(1) Okugcwele ukunwebeka nokuqina;
(2) Amandla afanele omshini, okuhlanganisa amandla okukhula, ukunwebeka kanye nokumelana nokudabuka.
(3) Ukusebenza okuzinzile, okunzima ukukhukhumala endaweni ephakathi nendawo, kanye nomphumela omncane wokuncipha kokushisa (umphumela we-Joule).
(4) Kulula ukuyicubungula nokuyibumba, futhi ingagcina usayizi oqondile.
(5) Akuyona into elimaza indawo yokuxhumana futhi ayingcolisi indawo yokuxhumana.
I-Ningbo Yokey Automotive Parts Co., Ltd igxile ekuxazululeni izinkinga zezinto zerabha zamakhasimende kanye nokuklama ukwakheka kwezinto ezahlukene ngokusekelwe ezimweni ezahlukene zokusetshenziswa.
