Cov ntawv roj hmab yog qhov tseem ceeb hauv kev lag luam, nrog rau lawv cov txiaj ntsig tau txhais los ntawm cov khoom siv tseem ceeb. Los ntawm cov roj hmab ntuj mus rau cov khoom siv hluavtaws thiab cov khoom siv rov ua dua tshiab, txhua yam muaj qhov ua tau zoo tshwj xeeb raws li cov kev siv tshwj xeeb, ua rau kev xaiv cov khoom tseem ceeb rau kev ua haujlwm zoo thiab ua haujlwm ntev. Hauv qab no yog cov ncauj lus kom ntxaws ntxaws ntawm cov ntaub ntawv roj hmab sib xws, lawv cov khoom, kev siv, thiab cov kev sib piv tseem ceeb.
Cov Khoom Siv Roj Hmab Tseem Ceeb: Cov Khoom & Daim Ntawv Thov
1. Ntuj Roj Hmab (NR) Cov Ntawv
Muab tau los ntawm cov ntoo roj hmab latex, NR nplooj ntawv yog khoom plig rau qhov tshwj xeeb elasticity (elongation mus txog 800%), siab tensile zog, thiab superior resilience. Lawv ua tau zoo nyob rau hauv nruab nrab kub (-50 ° C mus rau 80 ° C) tab sis muaj kev cuam tshuam rau roj, ozone, thiab UV hluav taws xob.
- Daim ntawv thov: General manufacturing gaskets, conveyor siv, automotive qhov rooj ntsaws ruaj ruaj, shock absorbers, thiab cov neeg siv khoom (xws li, roj hmab lev).
2. Nitrile (NBR) Cov Ntawv
Cov roj hmab hluavtaws ua los ntawm butadiene thiab acrylonitrile, NBR cov ntawv ua tau zoo hauv cov roj, roj, thiab tshuaj lom neeg. Lawv muab lub zog tensile zoo thiab ua haujlwm hauv qhov kub ntawm -40 ° C txog 120 ° C, txawm tias elasticity qis dua NR.
- Daim ntawv thov: Roj thiab roj pipelines, automotive engine gaskets, roj hoses, industrial tanks, thiab cov khoom ua zaub mov (qib NBR).
3. Silicone (SI) Cov Ntawv
Paub txog qhov kub thiab txias (-60 ° C txog 230 ° C, nrog qee qib mus txog 300 ° C), cov ntawv silicone tsis muaj tshuaj lom, hloov tau, thiab tiv taus ozone, UV, thiab kev laus. Lawv muaj lub zog tensile nruab nrab thiab tsis muaj roj tsis kam.
- Daim ntawv thov: Aerospace Cheebtsam, hluav taws xob rwb thaiv tsev, khoom noj khoom haus machinery, khoom kho mob (sterilizable), thiab high-temperature gaskets.
4. EPDM (Ethylene Propylene Diene Monomer) Cov Ntawv
Cov roj hmab hluavtaws uas muaj huab cua zoo heev, UV, thiab ozone tsis kam, EPDM cov ntawv ua haujlwm hauv -40 ° C txog 150 ° C thiab tiv taus dej, chav dej, thiab tshuaj me me. Lawv muaj cov roj tsis muaj zog tab sis zoo heev durability.
- Daim ntaub ntawv: Kev tsim kho cov dej tsis zoo (ru tsev, hauv qab daus), rwb thaiv tsev sab nraum zoov, lub qhov rais tsheb kaw, cov pas dej da dej, thiab HVAC systems.
5. Neoprene (CR) Cov Ntawv
Ua los ntawm chloroprene, cov nplooj ntawv neoprene muab kev sib xyaw ua ke ntawm kev hnav tsis kam, yoog raws, thiab nplaim taws retardancy. Lawv ua haujlwm nyob rau hauv -30 ° C mus rau 120 ° C thiab tiv taus ozone, UV, thiab tshuaj me me, nrog cov roj tsis zoo.
- Daim ntaub ntawv: Muaj hoses, tiv thaiv iav ( hnab looj tes, waders), marine seals, anti-slip flooring, thiab hluav taws xob tiv thaiv.
6. Recycled Rubber Sheets
Ua los ntawm cov neeg siv khoom tom qab (xws li, cov log tsheb) lossis cov khoom siv roj hmab tom qab kev lag luam, cov nplooj ntawv no yog eco-friendly, raug nqi zoo, thiab muaj kev hnav zoo. Lawv muaj qis elasticity thiab kub kam rau ua (-20 ° C txog 80 ° C) dua li cov ntaub ntawv nkauj xwb.
- Daim ntawv thov: Chaw ua si chaw, kis las kis las, chaw nres tsheb bumpers, suab rwb thaiv tsev, thiab cov ntaub pua tsev dav dav.
Kev sib piv kev ua haujlwm & kev ua haujlwm
Performance Metric NR NBR SI EPDM CR Recycled
Ua haujlwm tau zoo, txhua yam khoom siv hais txog qhov kev xav tau ntawm kev lag luam: NR thiab CR ua qhov tseem ceeb rau kev yooj yim rau kev siv zog (xws li, kev poob siab); NBR tsom rau tshuaj lom neeg / roj tsis kam rau kev lag luam; SI thiab EPDM ua tau zoo nyob rau hauv qhov chaw huab cua (siab kub / huab cua); thiab cov roj hmab rov siv dua cov nqi thiab kev ruaj ntseg rau kev siv tsis tseem ceeb.
Kev nkag siab txog qhov sib txawv no ua kom cov lag luam xaiv cov ntaub ntawv roj hmab zoo los ua kom zoo dua qub, txo cov nqi tu, thiab ua tau raws li cov qauv kev lag luam. Raws li kev siv thev naus laus zis, cov tuam txhab lag luam txuas ntxiv txhim kho cov khoom siv-xws li kev txhim kho EPDM cov roj tiv thaiv lossis txhawb nqa cov roj hmab rov ua dua tshiab-tshaj qhov kev sib tw ntawm cov ntawv roj hmab thoob ntiaj teb kev lag luam.
