Dab tsi yog Qhov Zoo ntawm Kev Siv Polyurethane Prepolymers rau Polyurethane Scrapers?
Polyurethane prepolymers tau paub ntau ntxiv rau lawv cov kev ua tau zoo thiab kev ua tau zoo hauv ntau daim ntawv thov, tshwj xeeb tshaj yog nyob rau hauv kev tsim cov polyurethane scrapers.
Muaj ntau qhov zoo ntawm Polyurethane Prepolymers:
Polyurethane prepolymers nthuav tawm tshwj xeeb txhua yam muaj zog thiab yoog raws, ua rau lawv zoo tagnrho rau cov scrapers uas yuav tsum tiv taus qhov hnyav thiab tsim kua muag. Cov khoom muaj peev xwm ua haujlwm siab ua kom ntseeg tau tias cov scrapers tuaj yeem ua tau zoo hauv cov khoom hnyav yam tsis muaj deformation mus tas li.
Ib qho ntawm cov yam ntxwv tseem ceeb ntawm polyurethane yog nws cov kev ua haujlwm zoo heev. Qhov kev ua tau zoo no yog qhov tseem ceeb rau cov scrapers siv nyob rau hauv ib puag ncig hnyav, xws li mining lossis kev tsim kho, qhov chaw uas lawv ntsib cov khoom siv tsis tu ncua. Tsis tas li ntawd, qhov cuam tshuam tsis kam ntawm polyurethane pab tiv thaiv kev puas tsuaj thaum lub sijhawm ua haujlwm, txuas ntxiv kev ua neej ntawm scrapers.
Polyurethane prepolymers ua kom pom kev txhim kho hydrolytic thiab tshuaj lom neeg ruaj khov piv rau lwm cov ntaub ntawv. Cov yam ntxwv no tshwj xeeb tshaj yog muaj txiaj ntsig zoo nyob rau hauv ib puag ncig uas cov scrapers tuaj yeem raug rau cov roj, roj, lossis lwm yam tshuaj. Kev ruaj ntseg ua kom ntseeg tau tias cov scrapers tuav lawv txoj kev ncaj ncees thiab kev ua haujlwm dhau sijhawm.
Lub peev xwm los txiav cov khoom ntawm polyurethane prepolymers tso cai rau cov tuam txhab tsim cov scrapers nrog cov yam ntxwv tshwj xeeb haum rau ntau yam kev siv. Piv txwv li, hloov cov formulation tuaj yeem ua rau cov khoom sib txawv ntawm cov hardness, resilience, thiab thermal stability. Qhov kev hloov pauv no ua rau kev tsim cov khoom tshwj xeeb scrapers uas ua tau raws li qhov xav tau ntawm kev ua haujlwm tshwj xeeb.
Polyurethane prepolymers feem ntau yog yooj yim los lis thiab txheej txheem dua li cov khoom siv thermoplastics. Lawv lub xeev cov kua dej thaum lub sij hawm thov tso cai rau kev sib tov ncaj qha thiab molding txheej txheem, ua rau lub sij hawm luv luv ntawm cov hlau lead thiab txo cov nqi siv[3][5]. Qhov kev ua tau zoo no tshwj xeeb tshaj yog rau cov tuam txhab nrhiav los tsim cov scrapers sai thiab raug nqi.
Ntau cov niaj hnub polyurethane prepolymers yog tsim los siv cov khoom siv bio-based, pab txhawb kev tsim khoom lag luam ntau dua. Kev siv cov peev txheej txuas ntxiv tsis tau tsuas yog txo cov kev cuam tshuam ib puag ncig tab sis kuj ua raws li kev tswj hwm kev nruj rau cov khoom lag luam eco.
Dab tsi yog Daim Ntawv Thov ntawm Polyurethane Scrapers?
Polyurethane scrapers pom siv ntau yam kev lag luam vim lawv cov khoom muaj zog:
Hauv kev ua haujlwm mining, scrapers raug rau cov xwm txheej hnyav thiab cov ntaub ntawv abrasive. Lub durability thiab hnav tsis kam ntawm polyurethane ua rau nws yog qhov kev xaiv zoo tshaj plaws rau daim ntawv thov no.
Scrapers siv nyob rau hauv kev tsim kho cov cuab yeej tau txais txiaj ntsig los ntawm polyurethane qhov cuam tshuam tsis kam thiab hloov tau yooj yim, ua kom ntseeg tau qhov kev ua tau zoo ntawm cov chaw ua haujlwm.
Hauv cov tshuab ua liaj ua teb, polyurethane scrapers pab tswj cov cuab yeej siv tau zoo los ntawm kev tshem cov khib nyiab zoo yam tsis muaj qhov chaw puas tsuaj.
