Abrasion kuj yog lwm tus yam ntxwv ntawm polyurethane elastomers. Hauv ntau daim ntawv thov kev lag luam, cov khoom siv tau raug kev sib txhuam tas li, qhov cuam tshuam qhov cuam tshuam, lossis zawv zawg sib cuag nrog lwm qhov chaw. Polyurethane cov ntaub ntawv paub zoo rau lawv cov hnav tsis kam, uas tso cai rau lawv tswj hwm lawv cov qauv kev ncaj ncees thiab kev ua haujlwm zoo nyob rau lub sijhawm ua haujlwm ntev. Cov cuab yeej no muaj txiaj ntsig tshwj xeeb hauv kev lag luam xws li mining, kev tuav cov khoom, thiab kev thauj mus los ntau qhov chaw uas cov khoom siv tau raug rau cov khoom siv abrasive.
Elasticity thiab cuam tshuam kuj tseem yog qhov zoo ntawm polyurethane casting. Polyurethane elastomers sib xyaw ua ke nrog cov neeg kho tshuab siab zog, tso cai rau lawv nqus cov shocks thiab vibrations yam tsis muaj cracking lossis deformation mus tas li. Cov khoom xws li kev poob siab absorbers, hloov tau yooj yim couplings, thiab cov ntaub thaiv kev tiv thaiv tau txais txiaj ntsig zoo los ntawm cov yam ntxwv no. Lub peev xwm rov qab tau lawv cov duab qub tom qab deformation txuas ntxiv lub neej kev pabcuam ntawm cov khoom thiab txo cov kev xav tau ntawm kev saib xyuas.
Lwm qhov zoo dua yog tias cov khoom siv polyurethane feem ntau xav tau kev saib xyuas qis. Thaum ntsia, ntau qhov chaw polyurethane ua haujlwm tau zoo nrog kev pabcuam tsawg lossis hloov pauv. Qhov no txo qis sijhawm rau cov tshuab thiab txo cov nqi ua haujlwm rau cov neeg siv kawg. Hauv kev lag luam uas cov khoom siv kev ntseeg siab ncaj qha cuam tshuam rau kev tsim khoom, qhov no ua rau muaj txiaj ntsig zoo rau kev lag luam ntawm cov khoom siv polyurethane.
Kev yuav cov ntaub ntawv polyurethane ncaj qha los ntawm cov tuam txhab tuaj yeem txhim kho cov nqi ua haujlwm ntxiv. Kev muab khoom ncaj nraim pab kom cov khoom zoo ib yam thaum txo cov nqi nruab nrab. Cov neeg tsim khoom tuaj yeem siv cov ntaub ntawv no los tsim cov khoom sib txawv ntawm tus kheej lossis tsim cov khoom loj dua uas npaj rau kev muag khoom. Qhov kev hloov pauv no ua rau polyurethane casting haum rau ob qho tib si rau cov haujlwm tshwj xeeb engineering thiab rau kev lag luam loj ntau lawm.
Polyurethane castingthev naus laus zis nws tus kheej kuj tseem muaj qhov ua tau zoo. Piv nrog rau qee yam kev tsim cov yas yas, polyurethane casting tuaj yeem siv nrog cov cuab yeej yooj yim thiab cov cuab yeej. Cov pwm siv nyob rau hauv casting feem ntau tsis tshua kim tshaj qhov yuav tsum tau rau siab -siab txhaj molding tshuab. Yog li ntawd, thawj zaug peev rau kev tsim khoom tuaj yeem qis dua, tshwj xeeb tshaj yog thaum tsim khoom nruab nrab lossis me me.
