Cov khoom ntawm polyurethane elastomer: hluav taws xob khoom
Cov hluav taws xob rwb thaiv tsev kev ua tau zoo ntawm polyurethane elastomer yog qhov zoo ntawm kev ua haujlwm kub, uas yog sib npaug ntawm cov roj hmab chloroprene thiab phenolic resin ester. Vim tias nws tuaj yeem ua tau ob qho tib si cam khwb cia thiab thermoplastic, nws feem ntau yog siv los ua cov khoom siv hluav taws xob thiab cov hlua cable. Cov khoom hluav taws xob ntawm polyurethane elastomer yog piv nrog cov khoom ntawm ntau yam khoom siv polymer (Table 1) thiab cov kua encapsulation polymers (saib Daim duab 2) Vim nws qhov siab molecular polarity thiab affinity rau dej, cov khoom hluav taws xob ntawm polyurethane elastomer sib txawv heev nrog cov av noo ib puag ncig. , thiab nws tsis haum rau siv raws li cov khoom siv hluav taws xob ntau zaus. Kev cuam tshuam ntawm ib puag ncig cov av noo thiab ntsuas hluav taws xob zaus ntawm cov khoom hluav taws xob ntawm polyurethane elastomer (saib Daim duab 3). Kev cuam tshuam ntawm cov qauv tshuaj elastomer thiab kev nqus dej ntawm nws cov khoom siv hluav taws xob (saib daim duab 4) Ntxiv rau, cov khoom hluav taws xob ntawm polyurethane elastomer txo qis nrog qhov kub thiab txias thiab nce nrog cov khoom hardness (saib Daim duab 5)
