Neoprene Rubber yog dab tsi?
Neoprene yog cov roj hmab hluavtaws ua los ntawm -polymerization ntawm chloroprene (2-chloro-}1,3-butadiene) uas yog siv dav hauv cov khoom siv tiv thaiv huab cua, nplaum khau khau, txheej, thiab foob pob hluav taws roj. Peb feem ntau hu nws: CR. Raws li lub ntsej muag muag muag rau lub hom phiaj dav dav, nws yog qhov tsim nyog rau kev tshaj tawm xws li cov roj tsiaj, cov roj zaub, cov roj inorganic lubricating, thiab cov slurries heev corrosive nrog pH variations tseem ceeb.
Cov tsos ntawm Neoprene yog milky dawb, beige, los yog lub teeb xim av flake los yog thaiv zoo li cov khoom, uas yog ib tug elastomer tsim los ntawm alpha polymerization ntawm chloroprene (ie . 2-chloro-1,3-butadiene). Lub solubility parameter ntawm chloroprene roj hmab account rau δ=9.2-9.41. Nws yog soluble nyob rau hauv toluene, xylene, dichloroethane, thiab trivanadium ethylene, me ntsis soluble nyob rau hauv acetone, methyl ethyl ketone, ethyl acetate, thiab cyclohexane, insoluble nyob rau hauv n-hexane cov kuab tshuaj nyob rau hauv cov kuab tshuaj uas tsim nyog. thiab cov kuab tshuaj tsis zoo thiab cov kuab tshuaj tsis zoo lossis cov kuab tshuaj tsis zoo thiab cov kuab tshuaj tsis zoo. Nws swells tab sis tsis yaj nyob rau hauv zaub roj thiab ntxhia roj.
Neoprene muaj lub cev zoo thiab txhua yam khoom, roj ua haujlwm, tiv thaiv tshav kub, nplaim taws, tshav ntuj tiv thaiv, ozone tsis kam, acid thiab alkali tsis kam, thiab tshuaj reagent kuj. Qhov tsis zoo yog qhov tsis zoo rau qhov txias txias thiab ruaj khov. Nws muaj lub zog tensile siab, elongation, thim rov qab crystallinity, thiab zoo adhesion. Resistant rau kev laus thiab kub. Zoo heev roj kuj thiab tshuaj corrosion kuj. Cov huab cua tsis kam thiab ozone aging kuj yog thib ob tsuas yog ethylene propylene roj hmab thiab butyl roj hmab. Lub tshav kub tsis kam yog sib npaug rau cov roj hmab nitrile, nrog rau qhov kub thiab txias ntawm 230-260 degree. Nws tuaj yeem tiv taus 120-150℃hauv lub sijhawm luv luv thiab tuaj yeem siv rau lub sijhawm ntev ntawm 80-100 degree, thiab muaj qee qhov hluav taws kub retardancy. Cov roj kuj txaus ntshai yog qhov thib ob tsuas yog cov roj hmab nitrile. Zoo tiv thaiv inorganic acid thiab alkali corrosion. Txawm li cas los xij, nws muaj kev tiv thaiv tsis zoo thiab tsis zoo hluav taws xob rwb thaiv tsev.
Thiab tam sim no cia peb tham txog dab tsi yog neoprene roj hmab siv rau?
Raws li cov yam ntxwv ntawm Roj resistant, Huab cua aging thiab corrosion kuj, daim ntawv thov ntawm neoprene yog raws li nram no.
1.Kev sib khi qhov chaw. Xws li Rubber sealing strips ntawm lub qhov rooj thiab qhov rais ntawm lub tsheb, txheej txheej ntawm cov roj raj, roj resistant roj hmab gasket ntawm nws pib cav, tsheb qhov rais qhia zawj. Cov cheeb tsam hauv tsev: Cov ntaub thaiv phab ntsa sealing sawb, lub qhov rooj tsis muaj dej tsis zoo thiab lub qhov rais sealing sawb, nthuav dav sib koom ua ke dej nres. Cov cuab yeej siv: Pipeline flange gaskets, corrosion-cov ntsaws ruaj ruaj rau cov khoom siv tshuaj.
2.Adhesive and coating field: Solvent based universal adhesive: siv rau kev sib txuas ntawm cov ntaub ntawv xws li ntoo, hlau, roj hmab, yas, thiab lwm yam. Piv txwv li, kev tsim khau thiab rooj tog sib dhos hauv cov khau factories. Anti corrosion coatings: tshuaj tank sab hauv phab ntsa txheej, nkoj lawj tiv thaiv plam txheej, sab nraum zoov steel qauv tiv thaiv xeb txheej. Sensitive nplaum: daim ntawv nplaum, daim kab xev kho mob substrate nplaum.
3. Cov khoom siv roj hmab: Cables: Cables siv hauv mines; tus tiv thaiv ntawm cov cables siv nyob rau hauv nkoj nkoj. Feem ntau siv nyob rau hauv acid thiab alkali resistant, ozone resistant tej yam kev mob. Nws yog qhov zoo heev siv nyob rau hauv ib puag ncig hnyav. Conveyor siv thiab roj hmab raj: Roj resistant conveyor siv, roj hmab hose rau tshuaj xa khoom, sab hauv txheej ntawm cov kav dej hydraulic. Cov khoom tiv thaiv kev ua haujlwm: hnab looj tes nrog cov kua qaub thiab alkali tsis kam, Hnav cov khau tiv thaiv, lub qhov ncauj qhov ntswg. Cov khoom lag luam poob siab: Cov khoom siv roj hmab poob siab siv hauv tsheb, cov khoom siv tsis zoo rau cov khoom siv, kev poob siab rau kev txhawb nqa choj.
4.Qee qhov chaw muaj kev lag luam tshwj xeeb: cov khoom siv hluav taws xob xws li hluav taws kub resistant hoses, conveyor siv rau mines thiab hluav taws kub resistant roj hmab los xij. Cov tub rog thiab Aerospace thaj chaw: Sealing qhov chaw rau Roj Tank ntawm lub dav hlau, Huab cua Resistant Roj Hmab Cheebtsam rau riam phom. Dej hiav txwv engineering thaj chaw: roj hmab sealing rau seawater desalination khoom, nkoj fender roj hmab strips (resistant rau seawater corrosion).
Ib qho kev siv tseem ceeb ntawm Neoprene roj hmab yog rau cov roj hmab sealing strips. Neoprene roj hmab sealing strips tuaj yeem siv rau ntau qhov chaw thiab ua raws li kev sib khi. Neoprene roj hmab sealing strips yog tsim los ntawm Neoprene roj hmab uas muaj elasticity zoo heev. Nws yog qhov zoo ntawm cov roj resistant, huab cua aging resistant, thiab hluav taws kub resistant yog li nws yog dav siv nyob rau hauv tsheb, tsev, thiab lwm yam industries. Kev ua haujlwm kub ntawm nws yog los ntawm -45 degrees rau 100 degrees. Vim muaj kev tiv thaiv zoo ntawm huab cua, nws tuaj yeem siv sab nraud rau ntau tshaj 20 xyoo.
