1. Nkucetelo wa muxaka wa inorganic flame retardant eka matirhelo ya low smoke halogen-free flame retardant EPDM insulation rubber material
Matimba ya tensile ya EPDM insulating adhesive material hi magnesium hydroxide hi yona leyikulu, ngopfu ngopfu hikokwalaho ka mhaka ya leswaku magnesium hydroxide i crystalline yofana na naliti, vukulu bya ti particle ehansi ka 2μm, naswona hiku cinciwa ka silane coupling agent ku tlakusa matimba yo boha xikan’we naku fambisana ka magnesium hydroxide na EPDM. Hi ku pimanisa oxygen index na vertical combustion grade, swi nga voniwa leswaku mbuyelo wa langavi retardant wa magnesium hydroxide wu antswa swinene ku tlula wa aluminium hydroxide, leswi swi vangiwa hi mahiselo ya thermal decomposition ya magnesium hydroxide ya le henhla ku tlula ya aluminium hydroxide hi ku tirhisa 140 ooveral , leswi papalataka ku cinca ka mati ku humelela ku humelela eka ku ya emahlweni ka ku ya emahlweni na mahiselo ya ku tirha ka processeum, ku tlula kwalaho ku humelela ka oxideum, leswi papalataka ku cinca ka mati ku humelela eka ku ya emahlweni ka ku ya emahlweni ka ku tirha ka ku tirha ka oxidde, leswi papalataka ku cinca ka mati ya le henhla ka mati hi ku tirhisa 140, leswi papalataka ku cinca ka mati ya le henhla ka mati hi ku tirhisa 140, leswi papalataka ku cinca ka mati ya le henhla ka mati hi ku tirhisa 140, leswi papalataka ku cinca ka mati ya le henhla ka mati swi humelela hi ku ya hi leswaku ku endliwa leswaku ku va na ku andza ka ku tirha ka oxideum. Adsorbed ehenhla ka adhesive material endzhaku ka dehydration naswona yi hlohletela ku endliwa ka malahla, leyi nga ta vumba leyara ya hard shell ehenhla ka adhesive material ku engetela, endzhaku ka dehydration, magnesium hydroxide yi ta vumba leyara ya oxidized film adsorbed ehenhla ka okisijini ya swilo, xisweswo yi antswisa ku vumbiwa ka khaboni, yi endla hard shell eka xiphemu xa le henhla ka rubber, isola leyi nga na okisijini. Ku pimanisiwa ka volume resistivity swinga gimetiwa, aluminium hydroxide eka EPDM insulation rubber material gezi insulation matirhelo ya impact i yitsongo swinene kutlula magnesium hydroxide, leswi swivangiwa hikuva ATH 104E conductivity ayi hundzi 60 ps-cm ~; na magnesium hydroxide ya ntolovelo, kufana na tinxaka ta ndlela ya ore ya vuhumelerisi, hikokwalaho ka xihlovo xa laha kaya xa nkucetelo wa mugodi, nhlayo yale henhla ya thyaka, ku basa ka le hansi, ku engetela eka vuandlalo bya yona na charge ya kahle, polarity yale henhla, microscopic internal stress, leswaku conductivity yifika eka 250 PS-CM. 1 kumbe ku tlula, nhlayo leyikulu ya magnesium hydroxide leyi engeteriweke eka nchumu wa rhaba ya EPDM yi ta endla leswaku swivumbeko swa ku pfalela ka nchumu wa rhaba swi hunguteka swinene, hambi leswi magnesium hydroxide endzhaku ka vutshunguri byo hlawuleka bya ku cinca ka le henhla byi nga antswisaka swivumbeko swo pfalela swa nchumu wa rhaba, kambe mbuyelo wa ha ri kahle. Loko ku tekeriwa enhlokweni nhlayo leyi fanaka ya magnesium hydroxide yi na swivumbeko swo antswa swo sivela malangavi ku tlula aluminium hydroxide, hina na vaendli va magnesium hydroxide hi ku hlanganela va antswisa swikombiso swa nyama swa magnesium hydroxide, tinxaka ta swihundzuluxi swa le henhla na tindlela ta vuhumelerisi, na swin’wana, na ku humesa tinxaka timbirhi ta magnesium hydroxide leti faneleke eka vuhumelerisi bya EPDM inhesive - Mh3055 na Mh305 na Mh305 na Mh305. MH3005Z.
MH3005 na MH3005Z EPDM insulating rubber tina high volume resistivity, laha insulating core leyi endliweke hi MH3005Z rubber hi xisekelo yi fikelelaka swilaveko swa IEC 60502, kambe swivumbeko swo pfalela swa MH3005 rubber swile henhla swinene. Hambiswiritano, matirhelo ya insulation ya core leyi endliweke hi MH3005 rubber ya le hansi swinene, naswona ku ringanyetiwa leswaku xivumbeko xa le henhla xa core xi onhakile hi nkarhi wa extrusion vulcanization, naswona xivangelo xi lava ku kamberiwa ku ya emahlweni.
Overall, compared with the EPDM insulation rubber with modified magnesium hydroxide alone and EPDM insulation rubber with aluminum hydroxide alone, the former has good flame retardant property, high tensile strength, and better insulating property after special surface modification, but there is still a risk of degradation of insulating property in the insulating wire core, while the insulating property of aluminum hydroxide is better, and its resistivity can meet the requirements even without modification.
.
Ku tirhisiwa kan’we ka magnesium hydroxide kumbe aluminium hydroxide inorganic flame retardant a swi nge swi koti ku fikelela swilaveko swa swivumbeko swa gezi na swivumbeko swo sivela malangavi, hikwalaho aluminiyamu ya hydroxide na magnesium hydroxide na vuyelo bya yona eka matirhelo ya 1 1205 000999. Ku tlakuka ka mpimo wa MH3005Z, viscosity ya Menni na matimba ya tensile ya EPDM insulating adhesive swi tlakukile, swivumbeko swa malangavi leswi sivelaka malangavi swi tlakukile, volume resistivity swi hungutekile. Hi ku tlakuka ka MH3005Z, menni viscosity na tensile strength ya EPDM insulating adhesive ya tlakuka, nhundzu ya flame retardant ya tlakuka, naswona ku lwisana ka volume ya hunguteka. Loko mpimo wa ATH 104E/MH3005Z wu ri 90/30, swivumbeko swa ku pfalela na ku sivela malangavi swa EPDM insulating adhesive swi fikelela swilaveko. Ku pimanisiwa ka ATH 104E / MH3005Z na mpimo wa 110 / 10 na 120 / LO timhangu timbirhi, hambi leswi ku tlakuka ka swiphemu swa 10 swa ATH 104E endzhaku ka EPDM insulation adhesive flame retardant properties swi antswisiwile, kambe swihlawulekisi swa xiviri swa ku hunguteka ka xihatla. Lath 104E / MH3005Z na mpimo wa 70 / 50 na 70 / 40 wa timhangu timbirhi, hunguta 10 wa swiphemu swa MH3005Z hambi leswi swi nga antswisaka swivumbeko swa ku pfalela swa rhaba, kambe swivumbeko swa ku sivela malangavi a swi fikelelangi swilaveko. Ku tiyisisa swivumbeko swa malangavi leswi sivelaka malangavi, nhlayo hinkwayo ya malangavi retardant ayi nge hungutiwi.
EPDM insulation rubber material Flameless smoke density i 355 kumbe ku tlula, na nhlayo ya inorganic flame retardant naswona kungari na vuxaka lebyi nga erivaleni na ratio, leswi swivangiwa hi formula ya swiphemu hinkwaswo, ku endliwa ka musi ngopfu ngopfu i EPDM, hambi leswi inorganic flame retardant yi nga antswisaka mapetrix ya maptrix.
3. Xiaki xo hunguta musi eka matirhelo ya xiaki xa EPDM lexi nga riki na ti- halogen lexi nga riki na ti- halogen lexi nga riki na musi
JB / T 10707 - 2007 'Thermoplastic Halogen-free low-smoke flame retardant cable materials' swi lava leswaku ku fanele ku engeteriwa musi lowu nga riki na malangavi wa nchumu wa rhaba a wu fanelanga wu va wukulu ku tlula 250, leswaku ku ta hungutiwa ku tala ka musi wa swilo swa rhaba swi fanele ku engeteriwa eka xitirhisiwa xo tshikilela musi. Montmorillonite yina calcium-based, sodium-based, magnesium-based montmorillonite, endzhaku ka ku hluvula naku hangalaka, ku basisiwa naku cinciwa, special organic composite, vukulu bya xikarhi bya leyara byi le hansi ka 25 nm. Montmorillonite yi hlawuriwa ku fikelela mbuyelo wo antswa wa musi.
Montmorillonite eka EPDM insulation rubber material musi ku tsindziyela ka ku khumbeka swi le rivaleni swinene, kambe swi nga ha tlhela swi va ku tlakuka kutsongo eka swivumbeko swa malangavi leswi sivelaka malangavi, kasi swivumbeko swin’wana swi na nkucetelo wutsongo; Hiku tlakuka ka nhlayo ya montmorillonite, EPDM insulation rubber material smoke density drop yihunguteke hakatsongotsongo, naswona yitala ku tshamiseka, hiku tekela enhlokweni swivangelo swa ntsengo, hlawula nhlayo ya montmorillonite eka 5 wa swiphemu.
4 Mahetelelo .
(1) Eka halogen-free-free low-smoke flame retardant EPDM insulating adhesive, mbuyelo wa flame retardant wa magnesium hydroxide lowu cinciweke lowu nga na mpimo lowu fanaka wu antswa ku tlula wa aluminiyamu hydroxide, kambe magnesium hydroxide yi na nkucetelo lowukulu eka swivumbeko swa ku pfalela ka gezi.
(2) Aluminium hydroxide na magnesium hydroxide naswona yi ri na mpimo wa 90 / 30, musi wa le hansi na halogen-free flame retardant EPDM insulation adhesive material yi na swivumbeko swa kahle swo sivela malangavi na swivumbeko swa insulation.
(3) Ku tirhisiwa ka montmorillonite swi nga hunguta hi ndlela leyinene ku tala ka musi wa xinamarheti xa ku pfaleriwa ka malangavi lama nga riki na ti- halogen lexi nga riki na musi wa le hansi, kambe hi ku engeteleka ka mpimo wa xona, ku tala ka musi wa xikhomela-ndhawu xa hunguteka hi ku nonoka, naswona mpimo lowunene wa montmorillonite i swiphemu swa 5.
