1. Tšusumetso ya inorganic kgabo retardant mofuta ka tshebetso ya tlaase mosi halogen-free kgabo retardant EPDM kwahelang rabara thepa
Matla a go goga a didirišwa tša sekgomaretši tša go thibela EPDM ka magnesium hydroxide ke tše kgolo kudu, kudu ka lebaka la gore magnesium hydroxide ke kristale ya go swana le nalete, bogolo bja dikarolwana tša ka fase ga 2μm, le ka phetošo ya sedirišwa sa go kopanya silane go godiša maatla a go tlama le go sepelelana ga magnesium hydrode le EPDM. Ka go bapetša tšhupamabaka ya oksitšene le maemo a go tšhuma a go ema, go ka bonwa gore mafelelo a go thibela kgabo ya magnesium hydroxide a kaone kudu go feta a aluminium hydroxide, se se bakwa ke themperetšha ya go bola ga phišo ya magnesium hydroxide e phagame go feta ya aluminiamo hydroxide ka 140 ° adsorbed on the surface of the adhesive material after dehydration and promote the formation of charcoal, which will form a layer of hard shell on the surface of the adhesive material In addition, after dehydration, magnesium hydroxide will form a layer of oxidized film adsorbed on the surface of rubber material, and promote the formation of carbon, forming a hard shell on the surface of rubber material, effectively isolating oxygen, thus improving the flame retardant system. Papiso ya bophahamo ba modumo resistivity ka phethwa, aluminium hydroxide ka EPDM kwahelang rabara thepa motlakase kwahelang tshebetso ya tšusumetso e nyenyane haholo ho feta magnesium hydroxide, sena ke hobane ATH 104E conductivity ha e feta 60 ps-cm ~; le magnesium hydroxide ye e tlwaelegilego, go swana le mehuta ya mokgwa wa ore ya tšweletšo, ka lebaka la mothopo wa ka gae wa khuetšo ya moepo, diteng tša godimo tša ditšhila, go hlweka ga fase, go tlaleletša go bokagodimo bja yona ka tefo ye botse, polarity ya godimo, kgatelelo ya ka gare ya microscopic, gore go swara go fihla go 250 PS-cm. 1 goba go feta, palo ye kgolo ya magnesium hydroxide yeo e okeditšwego go sedirišwa sa rabara ya EPDM e tla dira gore dithoto tša go thibela go tsena ga moya tša sedirišwa sa rabara di fokotšege kudu, le ge e le gore magnesium hydroxide ka morago ga kalafo ye e kgethegilego ya phetošo ya bokagodimo e ka kaonafatša dithoto tša go thibela go tsena ga moya, eupša dipoelo di sa dutše di se botse. Ge go lebelelwa palo ye e swanago ya magnesium hydroxide e na le dithoto tše kaone tša go thibela kgabo go feta batšweletši ba magnesium hydroxide ka mohlakanelwa ditšhupetšo tša mmele tša magnesium hydroxide, mehuta ya diphetoši tša godimo ga mmu le mekgwa ya tšweletšo, bjalobjalo, gomme di tšweletša mehuta ye mebedi ya magnesium hydroxide yeo e loketšego go dira gore e be ya EPDM le MH3005Z.
MH3005 le MH3005Z EPDM insulating rabara na phahameng bophahamo ba modumo resistivity, eo insulating konokono entsoeng ka MH3005Z rabara motheong kopana ditlhoko tsa IEC 60502, empa thepa insulating ya MH3005 rabara ba batlang e le phahameng. Le ge go le bjalo, tshepedišo ya go thibela go tsena ga moya ya motheo wo o dirilwego ka raba ya MH3005 e fase kudu, gomme go akanyetšwa gore sebopego sa godimo sa moko se senyegile nakong ya tshepedišo ya go ntšha vulcanization ya go ntšhwa, gomme lebaka le swanetše go hlahlobja gape.
Ka kakaretso, ha ho bapisoa le EPDM kwahelang rabara le fetotsoeng magnesium hydroxide le mong le EPDM kwahelang rabara le aluminium hydroxide le mong, pele o na le molemo kgabo retardant thepa, phahameng tensile matla, le molemo insulating thepa ka mor'a khethehileng holim'a phetolo, empa ho na le e ntse e le kotsi ea ho senyeha ho insulating thepa ka insulating terata e le eona e molemo, le ho insoluse e ntle.
2. Phello ya inorganic kgabo retardants ka tshebetso ya tlaase-musi, halogen-free kgabo retardant EPDM insulating sekgomaretsi
Tšhomišo e tee ya magnesium hydroxide goba aluminium hydroxide inorganic kgabo retardant e ka se fihlelele dinyakwa tša dithoto tša mohlagase le dithoto tša go thibela kgabo, ka fao aluminiamo hydroxide le magnesium hydroxide le khuetšo ya yona go tshepedišo ya go thibela kgabo ya go se be le halogen ya muši wa fase ya muši wa fase. Koketšego ya tekanyetšo ya MH3005Z, menni viscosity le go goga maatla a EPDM insulating sekgomaretši e ile ya oketšega, kgabo retardant thepa e ile ya oketšega, bophagamo resistivity fokotsehile. Ka go oketšega ga MH3005Z, menni viscosity le go goga maatla a EPDM insulating sekgomaretši eketša, kgabo retardant thepa e a oketšega, gomme bophagamo resistivity e a fokotšega. Ha karo-karolelano ya ATH 104E / MH3005Z ke 90/30, insulating le kgabo retardant thepa ya EPDM insulating sekgomaretsi kopana le ditlhoko. Papiso ya ATH 104E / MH3005Z le karo-karolelano ya 110 / 10 le 120 / LO maemo a mabeli, le hoja keketseho ea likarolo tse 10 tsa ATH 104E ka mor'a hore EPDM insulation sekgomaretsi kgabo retardant thepa e ntlafalitsoeng, empa thepa 'meleng, thepa ea 'mele ea ho fokotseha ka potlako. Lath 104E / MH3005Z le karo-karolelano ya 70 / 50 le 70 / 40 maemo a mabedi, fokotša dikarolo tše 10 tša MH3005Z le ge e le gore e ka kaonafatša dithoto tša go thibela go tsena ga moya, eupša dithoto tša go thibela kgabo ga di fihlelele dinyakwa. Gore go kgonthišišwe dithoto tša go thibela kgabo, palomoka ya sethibela kgabo e ka se fokotšwe.
EPDM insulation rabara thepa flameless mosi segokanyipalo ke 355 kapa ho feta, le palo ya inorganic kgabo retardant le ha ho na kamano e totobetseng le karo-karolelano, sena ke ka lebaka la formula ea dikarolo tsohle, sebopeho sa mosi ke haholo-holo EPDM, le hoja e inorganic kgabo retardant ka ntlafatsa kgabo re lokolloa, empa e ke ke lokolloa ke mosi o lokolloang.
3. Mosi Fokotsa moemeli ka tshebetso ya tlaase-musi halogen-free kgabo-retardant EPDM insulating motsoako
JB / T 10707 - 2007 'thermoplastic halogen-free low-musi retardant cable materials' e nyaka gore go se be le kgabo ya muši ya sedirišwa sa rabara ga se ya swanela go ba ye kgolo go feta 250, e le gore go fokotšwe segokanyipalo sa muši sa sedirišwa sa rabara go okeletšwa go sethibela muši. Montmorillonite e na le montmorillonite ye e theilwego godimo ga khalsiamo, ye e theilwego godimo ga sodium, yeo e theilwego go magnesium, ka morago ga go hlobola le go phatlalatšwa, go hlwekiša le go fetoša, motswako wo o kgethegilego wa organic, botenya bja magareng bja lera bo ka fase ga 25 nm. Montmorillonite e kgethilwe go fihlelela khuetšo ye kaone ya muši.
Montmorillonite ka EPDM kwahelang rabara thepa mosi segokanyipalo sa tšusumetso e hlakile haholo, empa hape e ka ba e nyenyane keketseho ea kgabo retardant thepa, ha thepa tse ling na le tšusumetso e nyenyane; Ka keketseho ea palo ea montmorillonite, EPDM kwahelang rabara thepa mosi segokanyipalo theoha butle-butle fokotswa, 'me a na le tshekamelo ya ho tsitsitse, ho nahana ka mabaka a ditjeo, khetha palo ea montmorillonite bakeng sa likarolo tse 5.
