Qhov Zoo Tshaj Plaws
Superior Swell Resistance tiv thaiv roj thiab roj
Txheem EPDM thiab dav dav -lub hom phiaj ua npuas ncauj degrade, o, thiab poob txhua yam clamping quab yuam thaum raug cov roj ntxhia lossis cov kua dej hydraulic. Polar acrylonitrile (ACN) qaum hauv BRT Rubber's NBR sponge compound nquag tawm tsam hydrocarbons, kom ntseeg tau tias lub foob tuav nws thawj tus ntoo khaub lig-section thiab dynamic sealing quab yuam.
Siab -Kev rov qab kaw-Cell Structure
Kev tswj tsis tau ntawm tes tawg ua rau ua rau ntxov ntxov ntxov ntxov. Peb cov txheej txheem microwave vulcanization tas mus li tsim ib qho kev kaw zoo li qub -cell matrix nrog cov hlwb tsis muaj nitrogen / cua. Qhov no tiv thaiv cov dej tsiv teb tsaws chaw raws txoj kab sib koom ua ke thiab txwv kev nqus dej kom tsawg dua 5% nyob rau hauv kev txuas mus ntxiv.
Tsawg Compression Teeb rau Ntev -Lub Sij Hawm Sealing Siab
Nyob rau hauv qhov nruam flange clamping los yog txee latching, qis - qib roj hmab ua npuas ncauj raug deformation mus tas li. BRT Roj Hmab ua kom zoo rau lub xeev vulcanization kom xa cov nqi qis qis (kuaj raws li ASTM D395), tiv thaiv kev ntxhov siab thaum lub sijhawm ua haujlwm tsis tu ncua.
Balanced Abrasion thiab Tear Durability
Cov khoom siv nkag mus rau qhov rooj, tshuaj xyuas lub kaus mom, thiab cov npog tsheb yuav tsum tau qhib thiab kaw. Peb cov NBR sponge formulation muaj ntau zog tensile thiab tsim kua muag kuj piv rau cov qauv mos foams, tiv thaiv gouging thiab nto puas thaum lub sij hawm installation thiab txij nkawm.
OEM Custom Manufacturing & Processing Capabilities
Precision Extruded Profiles
BRT Roj Hmab tsim kev cai NBR daim txhuam cev profiles tsim rau cov channel thiab flange haum:
• Geometry Peev Xwm: Rectangular strips, D-profiles, P- seals, di ncauj ntsaws ruaj ruaj, Hollow- noob foob, thiab kev cai co-extruded geometry.
• Fabricated Rings: Txias-spliceed los yog kub- molded ces kaum tsim seamless kawg gaskets rau roj- nruj enclosures.
CNC Tuag-Txiav & Hnia-Txiav
Rau lub ntsej muag tiaj tus sealing, twj tso kua mis flanges, thiab txoj hauv kev cutouts:
• High-precision CNC riam txiav thiab hlau- txoj cai tuag- txiav.
• Hnia-txiav gaskets muab rau ntawm cov yob txuas ntxiv rau kev ceev ceev los yog daim ntawv thov kab sib dhos.
Tshwj xeeb siab -Sensitive Adhesives (PSA)
Peb laminate siab -kev ua tau zoo nplaum rov qab tsim tshwj xeeb rau kev lag luam substrates:
• 3M 9448A / 3M 467MP: Superior thawj tack ntawm hlau, cam khwb cia hlau, thiab hmoov-coated txee.
• Roj-PSA siab ntev: Acrylic adhesive formulations uas tiv thaiv cov nplaum tawg nyob rau hauv ib puag ncig oily.
• Scrim / Mesh Carrier Daim kab xev: Tiv thaiv qhov profile stretching thaum lub sij hawm sib dhos.
