NBR-PVC Blend yog dab tsi?
Kev sib xyaw ntawm cov polymers tau txais kev txaus siab ntau vim tias nws tuaj yeem siv los tsim cov ntaub ntawv polymeric tshiab nrog cov khoom tshwj xeeb tsim nyog rau qee qhov tshwj xeeb.Cov khoom sib xyaw los ntawm acrylonitrile butadiene roj hmab (NBR) thiab polyvinyl chloride (PVC) tau tsim los rau cov khoom ua haujlwm hauv kev sib cuag nrog cov roj.Qhov PVC feem muab ozone, nplaim taws thiab huab cua tiv thaiv, qhov NBR feem muab kev puas tsuaj zoo thiab tshuaj tiv thaiv nrog rau cov roj, roj, thiab lwm yam tsis muaj polar compounds.
NBR / PVC elastomers yog siv nyob rau hauv ntau lub lag luam thiab kev lag luam nrog rau cov rooj tog zaum, lub tsev & kev tsim kho, tsheb sab hauv, khau, kev lag luam thiab khoom siv hauv tsev, thiab ntim khoom noj.Qee daim ntawv thov tseem ceeb suav nrog kev nyab xeeb khau khau, cov tshuab luam ntawv muag muag, cov ntaub pua tsev, cov tsho xim xim thiab cov xim hose npog.
Kev ua haujlwm ntawm NBR hauv kev hloov pauv hloov pauv hloov pauv PVC compound
Qhov sib ntxiv ntawm PVC rau NBR kuj tseem ua rau cov xim muaj peev xwm nqa tau hauv cov xim sib xyaw, ua rau kom zoo dua khaws cov xim ci.Cov khoom sib xyaw kuj nthuav tawm cov yas yas qis dua vim qhov muaj zog ntawm cov roj hmab nitrile rau cov khoom siv ua kua plasticizer.1
Raws li cov ntsiab lus ntawm PVC thiab plasticizer, NBR-PVC blends muab elasticity, nce compression teeb tsis kam, thiab zoo kub hloov tau yooj yim.Feem ntau, qhov elongation ntawm kev so nce nrog nce qib ntawm NBR thaum lub zog tensile nce nrog nce qib ntawm PVC.
Plexible PVC plasticized nrog cov pa plasticizers yuav plam plasticizer nyob rau hauv qee yam mob thiab ua nruj thiab nkig.Nyob rau hauv kev sib cuag nrog roj, NBR txo cov extraction ntawm plasticizer.Flexible PVC hloov nrog NBR poob qis dua thaum sib cuag nrog roj.Yog li ntawd, kev tuav pov hwm kev hloov pauv thiab kev ua haujlwm ntev dua tau ua tiav.
Nitrile Roj Hmab NBR Qhov Zoo
1. Plasticizer Persistence:NBR tuaj yeem ua rau PVC elasticity ntawm cov khoom thiab txo cov khoom siv plasticizer;Nyob rau tib lub sijhawm, vim nyiam cov plasticizers thiab txo cov kev tsiv teb tsaws ceev ntawm plasticizers.
2. Zoo heev Resistancerau roj, roj, hydrolysis thiab tshuaj: NBR muaj ntau ntawm CN pawg, uas tuaj yeem txhim kho cov roj thiab hnyav ntawm PVC.
3. Zoo Tsawg Kub Flexibility:Tsis muaj qhov hloov tau yooj yim thiab elastic saw qauv hauv PVC molecule, yog li nws qhov kev ua tau zoo ntawm qhov kub tsis zoo.Tom qab ntxiv PNBR elastomer, nws qhov kub thiab txias tsis kam yog txhim kho.
4. Zoo Abrasion Resistance:NBR tuaj yeem txhim kho qhov hnav tsis kam ntawm PVC thiab ua kom lub neej ua haujlwm ntev ntawm cov khoom.
5. Zoo Dimensional Stability:Lub yaj viscosity ntawm NBR / PVC yog qhov ruaj khov nyob rau hauv ntau qhov kub thiab txias, uas ua rau cov txheej txheem ua haujlwm ntawm cov khoom.
6. Ntev Ntev Flexibility:Raws li ib qho elastomer, NBR tsim cov qauv "hiav txwv-kob" thaum sib xyaw nrog PVC, uas ua rau muaj txiaj ntsig zoo ntawm PVC.
7. Roj hmab kov:PVC compound nrog NBR zoo nkaus li thiab kov zoo li Roj Hmab.
8. Cov rwb thaiv tsev zoo heev:Ntxiv NBR tuaj yeem txhim kho kev ua haujlwm ntawm cov khoom.
