Neoprenemuaj cov qauv tsis tu ncua thiab crystalline elongation.Cov roj hmab ntshiab muaj lub zog tensile siab, thiab vim tias nws cov saw molecular muaj cov tshuaj chlorine atoms, nws qhov kev ua tau zoo muaj cov yam ntxwv hauv qab no:
1) Zoo aging kuj thiab kub kuj.Vim tias cov tshuaj chlorine atom muaj lub luag haujlwm ntawm kev nqus hluav taws xob thiab tiv thaiv, yog li cov roj hmab neoprene muaj kev tiv thaiv kev laus.Tshwj xeeb tshaj yog huab cua aging thiab ozone aging kuj.Nyob rau hauv dav dav-lub hom phiaj roj hmab tsuas yog zoo ib yam li ethylene propylene roj hmab thiab butyl roj hmab, nws kub kuj thiab nitrile roj hmab sib npaug.Nws yog ib qho yooj yim los hloov xim tom qab tshav ntuj raug thiab yuav tsum tsis txhob siv raws li lub teeb xim los yog pob tshab khoom.
2) Zoo combustion kuj.Kev kub hnyiab tuaj yeem tso tawm ntau ntawm hydrogen chloride, tsuas yog carbonization tsis ncua kev sib txuas, kev tua tus kheej zoo.Nws cov nplaim tsis kam yog qhov zoo tshaj plaws hauv cov roj hmab uas siv dav dav.
3) Zoo tiv thaiv huab cua permeability.Nws yog thib ob tsuas yog cov roj hmab butyl thiab nitrile roj hmab, thiab zoo dua li cov roj hmab ntuj, butylbenzene roj hmab thiab butyl roj hmab.
4) Cov roj ua haujlwm zoo thiab tshuaj lom neeg ua haujlwm.Tsuas yog cov roj uas muaj ntxhiab hydrocarbon thiab chlorinated hydrocarbon roj, nws ruaj khov hauv lwm cov kuab tshuaj.Nws cov roj kuj zoo dua li cov roj hmab ntuj thiab SBR, tab sis tsis zoo li NBR.Nws yog resistant rau dav inorganic acids thiab alkalis, tab sis tsis rau concentrated sulfuric acid thiab concentrated nitric acid.
5)Neoprenetuaj yeem ua vulcanized nrog hlau oxides (xws li: magnesium oxide, zinc oxide).
Disadvantages: tsis zoo cia stability.General neoprene yog ib qho yooj yim rau hardening thiab deteriorate thaum lub sij hawm cia, feem ntau tsawg tshaj li ib xyoos ntawm 20 degrees Celsius, thiab feem ntau tsawg tshaj li rau lub hlis ntawm 30 degrees Celsius.Tab sis tsis yog-sulfur-regulated 54-1 hom cia lub sij hawm ntawm 30 degrees Celsius tuaj yeem mus txog 40 lub hlis.
Yuav ua li casneopreneua nrog nws?Qhov nrov stubby cooler, pleev hnab, hnab ntub dej, hnab tote, lub hnab laptop thiab lwm yam khoom siv ncaws pob yog ua los ntawm cov khoom siv neoprene.
