I ad effectum inorganicis flamma retardant types in perficientur de humilis-fumus halogen-liberum flamma retardant EPDM insulating Flexilis materiales
Tesserive viribus EPDM insulating tenaces materia cum Magnesium hydroxide est maxima, maxime ex eo quod
Magnesium hydroxide est acus, sicut crystallinum, particula magnitudine minus quam 2μm, et per modificationem Silanene copulata agente ad augendae et epdm et compatibility magnesii hydroxide et EPDM. Per comparet oxygeni index et vertical combustion gradus, quod potest videri quod flamma retardant effectus magnesium hydroxide est significantly melius quam de aluminium hydroxide, hoc est debitum ad excelsum decompositionis in more aeger est ex CXL Processing processus, sed Magnesium hydroxide erit formare iacuit de oxidized film adsorbed super superficiem ad tenaces materiam post siccitatibus et promovere in superficiem in superficiem et formationem in superficiem et ex convertis in superficiem, quam formationem in superficiem et in superficiem, et promovere ad formationem in superficiem, et promovere formation De Carbon, formatam durum testa super superficiem rubber materia, effective isolatur oxygeni, ita improving flamma retardant ratio. Comparison of volume resistivity can be concluded, aluminum hydroxide on the EPDM insulation rubber Ethylene propylene rubber (EPR), including binary ethylene propylene rubber and ternary ethylene propylene rubber (EPDM) two categories, is a saturated rubber, with excellent electrical insulation, moisture, heat, cold and aging resistance, is widely used in the preparation of wires and Cables, et fuit comprehendo alternative ad pelagus corpus de styrene-butadiene Flexilis ut funem inulatione materia. With the increasingly high requirements of the laying environment, wire and cable are being developed towards low-smoke halogen-free flame retardant, with the same low-pressure grades of cross-linked polyethylene, EPR also belongs to the flammable materials, its own molecular composition and structure of the flame retardant performance has little effect, only with a considerable amount of flame retardant in order to achieve the purpose of Flamma retardant, ita ut humilis-fumus halogen-liberum flamma-retardant materiae potest non solum addidit ad halogen-liberum genus de flamma retardants.

Halogen-liberum flamma-retardant EPR insulating Flexilis super annis, cum frequens occasiones ut subways et summus surge aedificia requirere altiore flamma et ad emendat in flammis et inquisitione et progressionem et magnesium modi, quod est in occursum est superius et magnesium, quod est in occursum est superius requisita.
I. Influence of De Flamma Retardant Type in perficientur de humilis fumus halogen-liberum flamma retardant EPDM EPDM Flexilis Material
Terle fortitudo EPDM insulating tenaces materia cum Magnesium hydroxide est maxima, maxime ex eo quod magnesium hydroxide est acus, sicut crystallinum, particula magnitudine minus quam 2μm, et per modificationem et compatibility magnesium hydroxide et in compatibilitate et compatibility magnesium et EPDM. Per comparet oxygeni index et vertical combustion gradus, quod potest videri quod flamma retardant effectus magnesium hydroxide est significantly melius quam de aluminium hydroxide, hoc est debitum ad excelsum decompositionis in more aeger est ex CXL Processing processus, sed Magnesium hydroxide erit formare iacuit de oxidized film adsorbed super superficiem ad tenaces materiam post siccitatibus et promovere in superficiem in superficiem et formationem in superficiem et ex convertis in superficiem, quam formationem in superficiem et in superficiem, et promovere ad formationem in superficiem, et promovere formation De Carbon, formatam durum testa super superficiem rubber materia, effective isolatur oxygeni, ita improving flamma retardant ratio. Comparatio of Volubilis resistentia potest concludi, aluminium hydroxide in EPDM Triticum Flexilis materia electrica velit perficientur de impulsum est multo minor quam magnesium hydroxide, quod est quia ath 104, and ordinary magnesium hydroxide, such as varieties of the ore method of production, due to the domestic source of the mine Influence, high impurity content, low purity, in addition to its surface with a positive charge, high polarity, microscopic internal stress, so that the conductivity is up to 250 pS-cm. I aut magis, magna numerus magnesium hydroxide addidit ad EPDM Flexilis materia et facere Flexilis materia scriptor insulating proprietatibus minuatur significantly, quamquam magnesium potest amplio in speciali superficiem et emendare potest amplio in proprietatibus in materia, sed eventus tamen non speciale. Considerans idem moles magnesium hydroxide est melius flamma retardant proprietatibus quam aluminium hydroxide, ut et magnesium hydroxide manufacturers communiter optimize physica Indicatores de modis, et productionem in EPDM et productio ad genera, et producendum ad producendum ad EPDM ad genes, et ad genera EPDM ad genera, et producendum ad producendum ad producendum ad EPDM ad genera, quod producendum ad genera ad genera ad genera etc. - mh3005 et mh3005 et mh3005z.
MH3005 et MH3005Z EPDM insulating Flexilis habere altum volumine resistentia, de quibus insulating core ex MH3005Z Flexilis basically occurrit requisita IEC (VI) DII, sed in proprietatibus MH3005 Flexilis sunt relative proprietatibus MH3005 Flexilis sunt relative. Tamen, in Nulla perficientur Core ex MH3005 Flexilis est relative humilis, et est aestimari quod superficies structura core laedi in extrusionem Vulcanization processus, et quod necesse est esse ulterius vulcanization processu, et quod necesse est esse amplius exploratur.
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 Melius et ejus resistentia potest occurrit requisita etiam sine immutatio.
II. Effectus inorganicis flammae retardants in perficientur de humilis-fumus, halogen-liberum flamma retardant EPDM insulating adhesives
Una Usus Magnesium hydroxide aut aluminium hydroxide inorganicis flamma retardant non eodem tempore occurrit in requisitis electrica proprietatibus et flamma retardant proprietatibus, sic in perficientur et magnesium halogen et ejus effectus in perficientur et magnesium halogen et eius effectus in perficientur et magnesium halden et eius effectum in perficientur et magnesium halogen et eius effectus in perficientur et magnesium halden et eius effectus in perficientur et magnesium halagen et eius effectus in perficientur et magnesium halogen et eius effectus in perficientur EPDM insulating tenaces, et in abundantia, et 104 MH3005Z dosage de summa CXX partes, cum incremento in dosis MH3005Z, in Menni Viscosity et Tensile Vires EPDM insulating tenaces auctus, flamma retardant proprietatibus auctus, volumine resistentia decrescebat. Cum autem augmentum MH3005Z, in Menni Viscositas et Tensile Virtus EPDM insulating tenaces crescit, flamma retardant res auget et volumine resisto decrescit. Cum autem Ratio aTh 104e / MH3005Z est 90/30, insulating et flamma retardant proprietatibus EPDM insulating tenaces occurrat. Compare Ath 104e / MH3005Z et Ratio CX / X et CXX / LO duo casibus, quamvis incremento X partes aTh 104e post EPDM TRANSIVIVUS Flamma Retardant PROBLENTES fuisse melius, sed corporis proprietatibus declinare. LATH 104E / MH3005Z et ratio LXX / L et LXX / XL duo casus, reducere X partes MH3005Z etsi non potest amplio per proprietatibus non obviam, sed non potest emendare proprietatibus proprietatibus et flammam non possessiones non occurrit, sed flamma retardant proprietatibus non occurrit, sed flammam retardant proprietatibus non occurrit, sed non poterit ad proprietatibus proprietatibus et in requisita. Ut ut flamma retardant possessiones, summa moles flammae retardant potest reduci.
EPDM Triticum Flexilis materiam flameless fumus density sunt CCCLV vel ita, cum moles inorganicis flamma retardant et non obvious relatione cum ratione, hoc est propter formulam omnium components, et non potest reducere et fumus, et non producit in Flamma, et non potest reducere et fumus, et non potest ad redigendum et fumus, et non potest reducere in Flame et non potest reducere et fumus, et non potest reducere in Flamma matrix Combustio.
III. Fumus reducing agente in perficientur de low-fumus halogen-liberum flamma-retardant EPDM insulating compositis
J. / T (X) DCCVII - MMVII 'Thermoplastic halogen-liberum humilis-fumus flamma retardant cable materiae requirit quod flamless CCL, ut ad redigendum et fumus supprimens. Montmorillonite continet calcium, secundum, sodium, secundum, magnesium, secundum Montmorillonite, post exuentes et dispersionem, purificationem et modificationem, specialem organicum compositum, in mediocris crassitudine est, minus quam XXV Mediocris crassitudine est, minus quam XXV Mediocris crassitudine est, minus quam XXV Mediocris crassitudine est, minus quam XXV Mediocris crassitudine est, quam XXV Minus quam in crassitudine, in crassitudine est minus, quam XXV NM. Montmorillonite est electus ad consequi melius fumus effectus.
Montmorillonite in EPDM Triticum Flexilis materia fumus density de impulsum est manifestum, sed etiam potest esse parva augmentum in flamma retardant possessiones, cum aliis proprietatibus non minus ictum; Cum incremento in moles montmorillonite, EPDM Triticum Flexilis materia fumus density gutta successive reducitur, et tendunt ad stabilized, taking in rationem sumptus factors, eligere moles montmorillonite pro V partibus.
IV conclusioni
(1) In the halogen-free low-smoke flame retardant EPDM insulating adhesive, the flame retardant effect of modified magnesium hydroxide with the same dosage is better than that of aluminum hydroxide, but magnesium hydroxide has a greater impact on the electrical insulation properties.
(II) Aluminium hydroxide et magnesium hydroxide et cum ratione XC / XXX, humilis fumus et halogen-liberum flamma retardant EPDM Stuulation tenaces materia est bonum flamma retardant et proprietatibus et proprietatibus.
