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

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 qho 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 hom tshuaj kua txiv thiab alkalis, cov tshuaj khov dua), thiab hluav taws xob zoo hluav taws xob.

Kev kho kab mob kev nkeeg - Kev haus dej phwj thiab kho mob

Tus qauv EPDMs feem ntau yog leej faj. Sulfur-cured compounds tau muab cov khoom yooj yim dua tab sis muaj ntau txoj hnyav thiab tsis tuaj yeem tsim kom muaj kev kub siab. Peroxide-kho lub plawv EPDMs muaj cua kub zoo thiab txo kom tsawg zaus. Nws ua raws ntev nrog kev siv tshwj xeeb tshaj yog rau kev tsim kho kev lag luam, tab sis tib lub sij hawm tseem kim thiab ntau nyuaj rau ntau tshaj li cov mis sulfur-kho.

Lwm Hom Variations

• Cov EPDMs feem ntau hauv tsev kho lub cev kom txhim kho yooj yim los yog txo cov kev sib txhuam rau cov ntawv thov dynamic.
• EPDMs tuaj yeem tsim cov khoom "white list" xwb raws li tau teev nyob hauv 21.CFR 177.2600 rau kev siv rau hauv cov ntawv uas tus elastomer yuav tiv tauj nrog khoom noj lossis dej haus.
• EPDMs tuaj yeem xa daim ntawv tso cai los ntawm National Sanitation Foundation (NSF) rau kev siv cov dej haus.
• EPDMs feem ntau siv hauv tsheb cua txias tshuab qhov twg R134a roj tub yees thiab POE los yog PAG lubricant thiab cov tub yees tshiab rau kev tiv thaiv ib puag ncig R744 siv. Nyob rau hauv R744 cua txias system, nws yuav tsum tau zoo heev ua hauj lwm rau kev nplua deg nyob rau hauv hydrogen dioxide ntawm kev kub siab thiab siab kub.
• EPDMs feem ntau yog siv nyob rau hauv phosphate ester type hydraulic fluids.

Qhia rau peb paub yog tias koj xav tau cov ntaub ntawv kom ua tau raws li cov qauv nram qab no: ROHS2.0, NSF, ASTM, FDA, KTW, WRAS, USP Class VI, los yog NORSOK M-710, Peb muaj ntau qhov tshwj xeeb uas muaj peev xwm ua tau raws li cov lus qhia koj tab tom nrhiav rau.
