Polyurethane hnav -}} Cov ntawv sau hluavtaws tshiab yog cov khoom siv molecular hluavtaws siab, muab tso rau ntawm cov roj hmab thiab yas. Nws ua ke lub zog siab ntawm cov yas nrog lub siab elasticity ntawm roj hmab.
Dav hardness si:
Txawm tias hauv qab hardness, nws tseem khaws tau lub elongation thiab resilience yog roj hmab. Lub hardness ntau ntawm polyurethane elastomers yog ntug dej A10 rau D80.
Lub zog siab:
Ntawm cov roj hmab - theem hardness, nws cov kua muag muaj zog yog ntau dua li cov dav dav- lub hom phiaj roj hmab. Ntawm qhov nyuaj, nws qhov kev cuam tshuam thiab khoov tau lub zog tseem muaj zog ntau dua li cov yas.
Hnav zoo heev:
Polyurethane belongs rau siab molecular organic elastomers, nrog cov khoom tiv thaiv zoo, flex tsis kam, thiab siab thauj} cov kabmob muaj peev xwm. Cov ntaub ntawv raw siv los tsim polyurethane pads undergo kev kho tshwj xeeb kom ntseeg tau tsis muaj delamination nyob rau hauv ntev- sij hawm lwm txoj kev hloov pauv.
Dej, corrosion, thiab kev tiv thaiv:
Polyurethane ta yog yooj yim los hloov thiab tswj, thiab lawv pab txo kom muaj kev siv ntau dua, ua rau lawv muaj kev tsim kho ntau ntawm loj - cov khoom teev.
Tsawg lub luag haujlwm:
Lawv ntsib cov qauv suab nrov ib puag ncig thiab muaj ntau cov kev siv nrog cov kws tshaj lij kev yoog tau.
Cov Kev Pab Nyiaj Txiag Tseem Ceeb:
Qib txij nkawm thiab cov kev pabcuam ntev ntev ua rau polyurethane porrats cov kev xaiv acepitable rau feem ntau ntawm cov lag luam yav tom ntej.
Cov Khoom Siv Khoom:
Polyurethane hnav - Cov khoom siv tau dav, kev tsheb thauj khoom, tshuab siv roj, khoom siv pob ncaws pob, thiab lwm thaj chaw.
Cov khoom lag luam raug xws li cov ntawv txheeb, cov pas nrig, cov roj hmab dampers, cov ntxaij vab tshaus, cov ntxaij vab tshaus, roj hmab, cov roj hmab rollers, textile chais, thiab lwm yam.
