HNBR70 Ntsuab Roj Hmab O Ring

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 hauj lwm thiab cov yam ntxwv cov khoom tshaj cov txheej txheem Nitrile.

Acrylonitrile ntsiab lus

Tib yam li NBR, muaj ntau theem ntawm Acrylonitrile (ACN) cov ntsiab lus hauv HNBR polymers sib txawv. ACN cov ntsiab lus muaj peev xwm ua tau ntau yam los ntawm 17% mus rau 49%. Txaus ACN cov ntsiab lus muab cov khoom kub zoo dua qub tab sis cov neeg pluag tsis zoo thiab cov roj hmab lub cev. Cov ntsiab lus ACN ntau dua qhov ua rau cov neeg tsis muaj zog txaus tab sis ua rau lub cev tsis muaj zog thiab cov roj ncov qaub ncaug tuaj. Txheem HNBRs feem ntau muaj 36% ACN cov ntsiab lus.

Kev kho cov kabmob - Peroxide-Cured

HNBRs yog feem ntau Peroxide-kho rau cov ntsiab lus sib tw ntawm Ge Mao. Nws kuj yog Sulfur-kho kom zoo hloov cov khoom nyob hauv dynamic system, tiam sis yuav txo qhov kub tsis kam thiab ua rau cov teeb meem tsis tuaj yeem teeb.

Lwm Hom Variations

• HNBRs feem ntau hauv tsev kho lub cev kom zoo dua qhov yooj yim ntawm kev txhim kho lossis txo cov kev sib txhuam rau cov ntawv thov dynamic.
• HNBRs tuaj yeem tsim cov khoom "white list" xwb raws li tau teev nyob rau hauv 21.CFR 177.2600 rau kev siv rau hauv cov ntawv thov uas tus elastomer yuav tiv tauj nrog cov zaub mov lossis dej haus.
• HNBRs feem ntau siv hauv kev tswj cua txias qhov twg R134a roj cua txias lossis cov tub yees tshiab rau kev tiv thaiv zoo li R401a, R404a, R410a, R507 thiab R744.
• Cov HNBRs kuj tau siv hauv tshuab hluav taws xob vim lawv txoj kev tsis sib haum xeeb zoo.
• Nyob hauv cov dej tob tob, nws yuav tsum muaj cov khoom tsis haum rau cov cua sov, cov roj crude, hydrogen sulfide, qhov cub thiab cov nplaum tawg. Cov sib xyaw tshwj xeeb ntawm HNBR tuaj yeem muaj rau daim ntawv thov no.
