Indandatho yokutywina yePolyurethane ibonakaliswa kukumelana nokuguguleka, ioyile, iasidi kunye ne-alkali, i-ozone, ukwaluphala, ubushushu obuphantsi, ukukrazula, impembelelo, njl. Indandatho yokutywina yePolyurethane inomthwalo omkhulu wokuxhasa umthwalo kwaye isetyenziswa kakhulu kwiindawo ezahlukeneyo. Ukongeza, indandatho yokutywina eyenziwe nge-cast ayixhasi ioyile, ayixhasi i-hydrolysis, ayigugi, kwaye inamandla aphezulu, afanelekileyo kwizixhobo zeoyile ezinoxinzelelo oluphezulu, izixhobo zokuphakamisa, izixhobo zomatshini zokubumba, izixhobo ezinkulu ze-hydraulic, njl.
Indandatho yokutywina yePolyurethane: i-polyurethane ineempawu ezintle kakhulu zoomatshini, kwaye ukumelana kwayo nokuguguleka kunye nokumelana noxinzelelo oluphezulu kuphezulu kakhulu kunezinye iirabha. Ukumelana nokuguga, ukumelana ne-ozone kunye nokumelana neoyile nako kulungile, kodwa kulula ukuyinyibilikisa kwiqondo lobushushu eliphezulu. Isetyenziswa ngokubanzi kwiikhonkco zokutywina ezimelana noxinzelelo oluphezulu kunye nokumelana nokuguguleka, ezifana neesilinda ze-hydraulic. Ngokubanzi, uluhlu lobushushu luyi - 45~90 ℃.
Ukongeza ekuhlangabezaneni neemfuno eziqhelekileyo zezinto zokuvala indandatho, indandatho zokuvala i-polyurethane kufuneka ziqwalasele le miqathango ilandelayo:
(1) Igcwele ukuthamba kunye nokuqina;
(2) Amandla afanelekileyo oomatshini, kuquka amandla okwandisa, ukwandiswa kunye nokumelana nokukrazula.
(3) Ukusebenza okuzinzileyo, kunzima ukudumba kwindawo ephakathi, kunye nesiphumo esincinci sokuncitshiswa kobushushu (isiphumo seJoule).
(4) Kulula ukuyicubungula nokuyibumba, kwaye inokugcina ubungakanani bayo buchanekile.
(5) Ayingcolisi umphezulu woqhagamshelwano kwaye ayingcolisi indawo engaphakathi.
I-Ningbo Yokey Automotive Parts Co., Ltd igxile ekusombululeni iingxaki zezinto zerabha zabathengi kunye nokuyila iindlela ezahlukeneyo zezinto ezisetyenzisiweyo ngokusekelwe kwiimeko ezahlukeneyo zokusetyenziswa.
