Sarudza Mutauro 
Kunze kwemamwe marudzi mashoma ekugadzira rabha, akawanda synthetic rubber zvigadzirwa , kufanana rabha chaiyo , vari zvinhu zvinopfuta kana kutsva . Mumaindasitiri akadai simba idzva, hurongwa hwebhatiri ,uye midziyo yemagetsi , yepamusoro-soro-inodzoreredza zvinodiwa zvinoiswa pazvikamu zverabha, kunyanya kune zvigadzirwa senge Battery Pads uye Halogen-Yemahara Flame-Retardant Vibration Dampers.
Parizvino, nzira huru dzehunyanzvi dzekuvandudza kunonoka kwemurazvo wezvigadzirwa zverubha sanganisira:
Kuwedzera zvinodzivirira moto kana mafiritsi anodzosa moto
Kugadzirisa kusanganisa nezvinhu zvinodzivirira moto
Kusuma mapoka ekushanda anopisa moto panguva ye polymerization
Kuwedzera crosslink density yezvigadzirwa zverabha
Zvikamu zvinotevera zvinopa kurongwa kupfupi uye tsananguro ye tekinoroji yerabha-inodzoreredza moto.
1. Flame-Retardant Technologies yeHydrocarbon Rubbers
1.1 Hunhu hweHydrocarbon Rubbers
Hydrocarbon rubbers kunyanya kusanganisira:
NR (Natural Rubber)
SBR (Styrene-Butadiene Rubber)
BR (Butadiene Rubber)
IIR (Butyl Rubber)
EPR / EPDM (Ethylene Propylene Rubber)
Nyangwe NBR (Nitrile Rubber) haisi yakajairika hydrocarbon rabha, yayo nzira dzekurapa dzinodzora murazvo akafanana uye anowanzo kukurukurwa pamwechete mumainjiniya maapplication.
Hunhu hunokosha hwehydrocarbon rubber hunosanganisira:
Kuderedza Oxygen Index (LOI): approx. 19–21
Thermal decomposition tembiricha: 200-500°C
Kutadza kunonoka kwemurazvo uye kusamira kupisa
Chizvarwa chezvizhinji zve magasi anopisa panguva yekupisa
Saka, kana inoshandiswa mu Battery Pads, Industrial damping pads , kana general vibration yekuzviparadzanisa nevamwe zvikamu , kugadziridzwa kusingadzoreki kwemoto kunokosha.
1.2 Nzira Dzakafanana neMurazvo-Retardant dzeHydrocarbon Rubbers
(1) Kusanganiswa neFlame-Retardant Polymers
Nekusanganisa marabha ehydrocarbon ane mapolymer anodzoreredza moto senge:
Polyvinyl Chloride (PVC)
Chlorinated Polyethylene (CPE)
Chlorosulfonated Polyethylene (CSM)
Ethylene-Vinyl Acetate (EVA)
kunonoka kwemurazvo kunogona kuvandudzwa kusvika pamwero wakati. Panguva yekubatanidza, kunyanya kukoshesa kunofanira kubhadharwa:
Kuenderana kwezvinhu
Co-crosslinking system dhizaini
Iyi nzira inonyanya kushandiswa structural Battery Pads kana kwete-yakakwirira-elasticity damping zvikamu.
(2) Kuwedzera kweFlame Retardants (Primary Approach)
Kuwedzera kwe zvinodzivirira moto ndiyo inonyanya kukosha nzira yekusimudzira kunonoka kwemurazvo muma hydrocarbon rubber uye inogona kuvandudzwa kuburikidza synergistic systems.
Organic halogen-based flame retardants (chinyakare mhinduro):
Hexachlorocyclopentadiene derivatives
Decabromodiphenyl ether
Chlorinated parafini
Inorganic synergistic flame retardants:
Antimony trioxide (Sb₂O₃) (inowanzo shandiswa)
Zinc borate
Aluminium hydroxide
Ammonium chloride
⚠ Zvinokosha:
Halogen-based flame retardants haifanirwe kunge iine halogens dzakasununguka , zvikasadaro vangadaro:
Corrode processing equipment uye molds
Deredza magetsi ekudzivirira kushanda
Negatively kukanganisa kuchembera kuramba
Mu simba idzva uye maindasitiri ezvemagetsi, Halogen-Yemahara Flame-Retardant Vibration Dampers vave vemazuva ose, zvichiita kuti pave nechido chakasimba che halogen-isina flame-retardant systems.
(3) Kuwedzera kweFlame-Retardant Inorganic Fillers
Inowanzoshandiswa fillers inosanganisira:
Calcium carbonate
Kaolin ivhu
Talc
Precipitated silica
Aluminium hydroxide
Iyi nzira inovandudza kunonoka kwemoto:
Kuderedza chikamu che zvinobvira organic zvinhu
Kushandisa iyo endothermic decomposition effect ye fillers
Semuyenzaniso:
Calcium carbonate uye aluminium hydroxide tora kupisa kwakanyanya panguva yekuora
Zvisinei, pfungwa inofanira kubhadharwa kune chokwadi chokuti:
Yakawandisa filler kurodha kunoderedza mechanical properties
Haina kukodzera high-elasticity kana high-damping vibration isolation components
(4) Kuwedzera Rubber Crosslink Density
Zvidzidzo zvakaratidza izvozvo:
Higher crosslink density → Idekisi yeokisijeni yepamusoro → Kudzoreredza kwemurazvo kwakavandudzwa
Iyi michina inogona kunge yakabatana neiyo kuwedzera kwekushisa kwekuparara kwekupisa.
Iyi nzira yakashandiswa zvinobudirira mukati EPDM rubber systems uye inokodzera:
Bhatiri Mapedhi anoshandiswa munzvimbo dzepakati-kusvika-pamusoro tembiricha
Structural flame-retardant vibration damping rubber components
2. Flame-Retardant Characteristics yeHalogenated Rubbers
Halogenated rubbers masikirwo ane halogen zvinhu uye anowanzo ratidza:
Oxygen index: 28-45
FPM (Fluororubber) oksijeni index inodarika makumi matanhatu neshanu
Yakakwira halogen yemukati → nani murazvo retadancy
Kuzvimisa kuzvibata mushure mekubvisa murazvo
Nekuda kweizvozvo, kurapa-kurebesa moto kwehalogenated rubber kuri nyore, kazhinji kunongoda kusimbiswa kudiki nemaretardants.
⚠ Zvisinei, nokuda mitemo yezvakatipoteredza (zvakaita se RoHS uye REACH ) uye mafambiro mu indasitiri itsva yesimba, halogen-isina mhinduro vari kuwedzera kufarirwa. Ichi ndicho chikonzero chikuru chekugamuchirwa kwakapararira kwe Halogen-Yemahara Flame-Retardant Vibration Dampers.
3. Flame-Retardant Technologies yeHeterochain Rubbers
Mumiririri mukuru heterochain rubber ndizvo:
Dimethyl Silicone Rubber (VMQ)
Hunhu hwayo hunokosha hunosanganisira:
Oxygen index inosvika makumi maviri neshanu
Thermal decomposition tembiricha inosvika 400-600°C
Excellent high-temperature kugadzikana
Moto unodzoreredza nzira dzesilicone rabha dzinonyanya kusanganisira:
Kuwedzera thermal decomposition tembiricha
Kuwedzera huwandu hwe yasara char mushure mekuora
Kuderedza chiyero chechizvarwa chegasi rinopisa
Semagumo, silicone rabha inoshandiswa zvakanyanya mu:
High-tembiricha Battery Pads
High-end halogen-isina flame-retardant damping components
Dziviriro yekuvharira zvikamu zvemagetsi uye magetsi matsva emidziyo
Mhedziso
Dhizaini inodzoreredza murazvo we zvigadzirwa zverabha inofanira kutariswa zvizere zvichibva pa rudzi rwerabha, application environment ,uye kudzora zvinodiwa.
Zvemaapplications akadai:
Battery Pads
Halogen-Yemahara Flame-Retardant Vibration Dampers
zvinokurudzirwa kuisa mberi:
Halogen-isina murazvo-retardant masisitimu
Yakakodzera crosslink density dhizaini
Yakaenzana mhinduro pakati pemoto-inodzoreredza mafirita uye mashandiro emuchina
Kunze kwemhando shoma dzekugadzira rabha, dzakawanda synthetic rubber zvigadzirwa , kufanana natural rabha , vari zvinhu zvinopfuta kana kupfuta.
