Polyurethane hnav-cov khoom tiv taus yog ua los ntawm siab-molecular- cov khoom hnyav polyurethane, muaj kev hnav zoo heev, kev cuam tshuam, thiab elasticity. Nws hnav tsis kam deb tshaj li cov roj hmab zoo tib yam lossis qee cov ntaub ntawv hlau, tso cai rau kev siv sijhawm ntev hauv siab - kev sib txhuam, siab - cuam tshuam ib puag ncig yam tsis muaj qhov tseem ceeb. Polyurethane kuj pom zoo corrosion kuj, acid thiab alkali tsis kam, roj kuj, thiab kev laus kuj. Cov khoom siv hardness thiab elasticity tuaj yeem hloov kho los ntawm kev tsim kom tau raws li qhov xav tau ntawm cov khoom sib txawv thiab cov khoom siv.
Lub voj voog txij nkawm rau kev hnav- cov khoom tiv thaiv polyurethane feem ntau cuam tshuam los ntawm cov cuab yeej ua haujlwm ib puag ncig, cov yam ntxwv ntawm cov khoom siv, thiab cov khoom ua haujlwm ntawm cov khoom lawv tus kheej. Nyob rau hauv siab - hnav thiab siab - cuam tshuam rau kev ua haujlwm - xws li cov uas pom nyob rau hauv cov mining crushers, pob zeb, thiab cov khoom siv sib sau ua ke- cov khoom siv tau tshwm sim sai dua, yuav tsum tau kuaj xyuas thiab tu ntau zaus. Hloov pauv, nyob rau hauv qis- hnav thiab qis- qhov cuam tshuam ib puag ncig- xws li cov khoom noj khoom haus, kev lag luam lub teeb, lossis cov cuab yeej tiv thaiv ib puag ncig- lub voj voog kev saib xyuas tuaj yeem txuas ntxiv kom tsim nyog. Cov khoom siv khoom siv-xws li hardness, particle size, ya raws, thiab corrosiveness{13}} kuj cuam tshuam ncaj qha rau tus nqi ntawm cov khoom hnav. Tsis tas li ntawd, qhov sib txawv ntawm cov khoom sib txawv ntawm qhov nyuaj, qhov ntom ntom, thiab hnav- qhov ntsuas tsis kam yuav ua rau muaj qhov sib txawv ntawm kev saib xyuas; Cheebtsam featuring siab hnav tsis kam thiab siab hardness feem ntau yuav tsum tsis tshua muaj txij nkawm.
Feem ntau, hnav-cov khoom tiv thaiv polyurethane yuav tsum tau soj ntsuam ib ntus ntawm peb lub hlis twg lossis ib nrab xyoo-ib xyoos txhawm rau txheeb xyuas qhov hnav, tawg, lossis deformation. Rau cov khoom siv uas muaj kev hnav siab, qhov kev tshuaj ntsuam xyuas yuav raug luv luv rau ib lub hlis, nrog rau kev saib xyuas tshwj xeeb rau cov chaw tseem ceeb xws li cov hlua, cov hlua, thiab cov vibrating screen decks. Thaum kuaj xyuas, txhua yam khoom uas pom tias hnav hnyav lossis cov khoom uas cuam tshuam rau cov cuab yeej ua haujlwm ib txwm yuav tsum tau hloov lossis kho tam sim ntawd. Tsis tu ncua tu cov khoom tso nyiaj thiab cov khoom seem ntawm cov khoom seem, thaum tswj xyuas qhov chaw ua haujlwm huv, tuaj yeem ua rau lawv lub neej ua haujlwm tau zoo. Los ntawm kev tshawb fawb tsim cov sijhawm saib xyuas thiab ua raws li cov txheej txheem kev ua haujlwm, nws muaj peev xwm ua kom ntev lub neej ntawm kev hnav-cov khoom tiv thaiv polyurethane, yog li txo cov nqi tu cov cuab yeej thiab txhim kho kev tsim khoom.
