Kev Kub Hlwb Range Chart

Qhov sib txawv ntawm qhov kev pab no yog rau kev siv xwb.
Hauv qhov chaw ib puag ncig, qee lub tebchaw muaj peev xwm tsis ncav lub siab tshaj plaws raws li qhia hauv daim phiaj xwm no. Txawm li cas los xij, qhov kub siab dua tuaj yeem raug tau yog tias raug kis tau luv luv los yog sib quas ntus.

Roj Thiab Kub Tshav Kub Sib Piv Sib Peem

XLONG muab ntau tshaj 10 hom elastomer rau neeg xaiv:

Nitrile Roj Hmab (NBR)

Nitrile roj hmab, tseem hu ua NBR los yog Noob, Nws yog ib qho siv feem ntau siv sealing elastomers vim nws tsis tuaj yeem ua rau roj av fuels thiab lubricants thiab nws tus nqi qis dua. Nitrile elastomers yog copolymers ntawm acrylonitrile thiab butadiene. Muaj ntau ntau hom kev sib txawv ntawm nitrile tebchaw.

Ethylene Propylene Rubber (EPR, EPDM)

EPDM yog ib tug copolymer ntawm ethylene thiab propylene, thiab ntxiv rau terpolymer ntawm ethylene thiab propylene nrog ib tug me me ntawm ib tus thib peb monomer (feem ntau ib diolefin) kom pom zoo rau vulcanization nrog sulfur. Feem ntau Ethylene Propylene Roj Hmab muaj kev xyuam xim zoo heev rau kev ua rau lub hnub nyoog, hnub ci thiab huab cua, thiab muaj kev ywj pheej zoo ntawm qhov kub, tshuaj tua tsis zoo (ntau cov dej ntim thiab alkalis, cov tshuaj khia dej), thiab hluav taws xob zoo hluav taws xob.

Fluorocarbon (FPM, FKM)

Fluorocarbon yog ib txoj kev ua haujlwm zoo heev, thiab tshwj xeeb tshaj yog nws muaj kev tiv thaiv zoo rau kev kub, ua rau huab cua, roj, cov roj hluav taws, roj, hydraulic kua, aromatics thiab ntau cov organic solvents thiab tshuaj.

Hydrogenated Nitrile Roj Hmab (HNBR)

Hydrogenated Nitrile (HNBR) yog ib qho hluavtaws polymer uas tau txais los ntawm cov khoom sib xyaws rau nitrile cov butadiene theem nrog hydrogen, thiab nws tseem hu ua HSN (Highly Saturated Nitrile). Qhov tshwj xeeb kev ua kom hydrogenation thiaj li muaj ntau ntau cov khoom sib txuas hauv cov ntsiab choj ntawm NBR polymer, yog li HNBR muaj superior kub, ozone, tshuaj lom neeg ua haujlwm thiab cov yam ntxwv cov khoom tshaj li tus qauv Nitrile.

Silicone Rubber (MQ, VMQ, PVMQ)

Lub cev, silicones yog raws li silicon, lub caij muab los ntawm quartz. Los tsim cov hoob kawm ntawm hluavtaws elastomers, pendant organic pawg xws li methyl, phenyl thiab cov hlua txuas nrog silicon atoms. Qhov sib ntxiv ntawm sab chains tuaj yeem ua kom muaj kev sib txawv hauv cov khoom. Silicones muaj cua kub zoo heev, nws muaj zog thiab muaj zog tiv thaiv kab mob, zoo dielectric stability, thiab ua rau ntau cov roj, tshuaj, thiab cov kuab tshuaj. Thiab rau tag nrho cov elastomers, silicones muaj qhov zoo tshaj plaws cov khoom yooj ywm ntawm qhov tsawg. Tab sis nws kuj muaj qee yam tsis muaj zog xws li lub zog tsis muaj zog, tsis tsim kua muag thiab hnav tsis taus.

Chloroprene roj hmab (CR)

Chloroprene yog ib qho ntawm thawj cov khoom cua zoo thawj zaug hauv xyoo 1931 los ntawm Dupont, thiab lub npe hu ua Neoprene. Nws yog npaj los ntawm emulsion polymerization ntawm chloroprene, los yog 2-chlorobutadiene. CR yog ib lub tswv yim siv ntau lub ntsiab lus uas ua rau lub zog ua ke ntawm cov khoom. Nws muaj qhov tsis zoo rau lub hnub, ozone, huab cua thiab ua haujlwm zoo nrog cov roj thiab ntau yam tshuaj. Nws kuj qhia txog lub cev muaj zog thiab kev tawm tsam zoo rau hluav taws.

Fluorosilicone roj hmab (FVMQ)

Fluorosilicone zoo ib yam li cov roj hmab, cov khoom cog rau trifluoropropyl, methyl, thiab cov hlua li ntawm cov saw hlau. Cov neeg kho tshuab thiab lub cev muaj ntsis zoo ib yam li VMQ. Txawm li cas los xij, FVMQ muaj cov roj thiab cov pob zeb ua haujlwm tsis zoo tuaj, tab sis cov neeg tsis tuaj yeem ua rau huab cua txias dua VMQ.
