Kafukufuku wotsika ndi utsi wotsika ndi ntchentche mfulu yamphamvu ethylene ma proble

Ethylene Proble rabara (ERI), kuphatikizapo ma propylene ma probylene Proble Hiplent Proble (Epdm) Ndi zofuna za malo okhala, waya ndi chingwe zikupangidwa kukhala ndi utsi wopanda utsi, zomwe zimapangidwanso ndi zotupa za polyethylene, zokhazokha za moto woyaka, Chifukwa chake kuti mupange utsi wotsika-flamen-romdant-reacklent amatha kuwonjezeredwa ndi gulu lopanda lala la halogen wolabadira. Kafukufuku wawonetsa kuti magetsi a Epdm amakhudzidwa kwambiri ndi lala, kungowonjezera magawo 80 a hydroxide yamphamvu kutentha kwambiri kwa kukana /> ​​3.67 mce -km ndi volidy ≥ 3.67 mcested ≥ (nthawi yomweyo) Zovuta. Izi zapangitsa kuti ikhale yocheperako yamphamvu yotsika mtengo patadutsa zaka zambiri, pomwe nyumba zapamwamba komanso zokwera kwambiri zimafuna kuti moto wonse ukhale wotetezeka. Ndiukadaulo wosinthika wa itorgeton okhazikika monga aluminiyamu hydroxide ndi kafukufuku wa njira zatsopano zopangira, ndizotheka kukwaniritsa zofunikira pamwambapa.

1 zotsatira za itorganic Flamentant Mitundu Yoyenda Pamayendedwe Otsika-Flame-Free Flame Hilday Epdm Epdming EPDM

Mphamvu yamphamvu ya Epdm Imbitsitsani zomatira ndi magnesium hydroxide ndiye wamkulu kwambiri, makamaka chifukwa chakuti

Magnesium hydroxide ndi monga Crystalline, kukula kwa tinthu kochepera 2μm, ndipo kudzera mu kusintha kwa wothandizila ku Silane kuti athandize mphamvu yakumanga ndikugwirizana kwa Epdroxide ndi EPDM. Poyerekeza mlozera wa oxygen ndi kalasi yolumikizira, imatha kuwoneka kuti lalaya imagwira bwino kwambiri kuposa aluminium hydroxide pasadakhale Njira, mochuna Magnesium hydroxide imapanga wosanjikiza wa filimu yomata pazinthu zomata zam'mimba Kupanga chipolopolo cholimba pamtunda wa mphira, moyenera mpweya, motero amawongolera dongosolo lamoto. Kuyerekeza kwa kuchuluka kwa kuchuluka kwa kuchuluka kwake kumatha kutsimikizika, aluminiyamu hydroxide pa epd ethylene ma proprable andylene proble ndipo yakhala njira yokwanira ku thupi lalikulu la mphira wa styrene-butadiene ngati zinthu zotchinga. Ndi zofuna za malo okhala, waya ndi chingwe zikupangidwa kukhala ndi utsi wopanda utsi, zomwe zimapangidwanso ndi zotupa za polyethylene, zokhazokha za moto woyaka, Chifukwa chake kuti mupange utsi wotsika-flamen-romdant-reacklent amatha kuwonjezeredwa ndi gulu lopanda lala la halogen wolabadira. Kafukufuku wawonetsa kuti magetsi a Epdm amakhudzidwa kwambiri ndi lala, kungowonjezera magawo 80 a hydroxide yamphamvu kutentha kwambiri kwa kukana /> ​​3.67 mce -km ndi volidy ≥ 3.67 mcested ≥ (nthawi yomweyo) Zovuta. Izi zapangitsa kuti ikhale yocheperako yamphamvu yotsika mtengo patadutsa zaka zambiri, pomwe nyumba zapamwamba komanso zokwera kwambiri zimafuna kuti moto wonse ukhale wotetezeka. Ndiukadaulo wosinthika wa itorgeton okhazikika monga aluminiyamu hydroxide ndi kafukufuku wa njira zatsopano zopangira, ndizotheka kukwaniritsa zofunikira pamwambapa.

1. Mphamvu ya itorganiac Flamentant Affice Pamayendedwe Ochepera-Flame-Free Flame Hitday EPD

Mphamvu yakuwoneka ya epdm yolumikizira zomatira ndi magnesium hydroxide ndiye kuti magranesium hydroxide ndiosachepera magnesium hydroxide ndi epdm. Poyerekeza mlozera wa oxygen ndi kalasi yolumikizira, imatha kuwoneka kuti lalaya imagwira bwino kwambiri kuposa aluminium hydroxide pasadakhale Njira, mochuna Magnesium hydroxide imapanga wosanjikiza wa filimu yomata pazinthu zomata zam'mimba Kupanga chipolopolo cholimba pamtunda wa mphira, moyenera mpweya, motero amawongolera dongosolo lamoto. Kufanizira kwa kuchuluka kwa kuchuluka kwa kuchuluka kwake kumatha kutsimikizika, aluminiyamu hydroxide pazinthu zamagetsi za EPDM Ndipo wamba magnesium hydroxide, monga mitundu yazomwe zimapangidwira, chifukwa cha gwero lapanyumba, zodetsa kwambiri, kupsinjika kwakukulu, kuloza kwa mawonekedwe a 250 ps cm. 1 kapena kupitilira apo, kuchuluka kwa magnesium hydroxide kuwonjezeredwa ku zinthu za mphira kudzaza zomwe zimawonongeka kwambiri, ngakhale magnesium hydroxide pambuyo pa mankhwala a mphira, koma zotsatira zake sizabwino. Kuganizira kuchuluka komweko kwa magnesium hydroxide kuli bwino kwambiri kuposa ma aluminium hydroxide, mitundu yopanga magnesium hydroxide yopanga zomata - Mh3005 ndi Mh3005 ndi Mh3005Z.

Mh3005 ndi Mh3005Z EPDM Imbikitsitsani rabar ali ndi mphamvu yayitali, yomwe imakhazikika pamtundu wa Mh3005z kwenikweni zimakwaniritsa zofunikira za iec. Komabe, magwiridwe antchito a pakati pa mh3005 rabara ndi ochepa, ndipo akuti mawonekedwe a pachimake anali atawonongeka poyambira, ndipo chifukwa chake akuyenera kuwunikiranso.

Ponseponse, poyerekeza ndi EPDM Stratetion Hydroider Hydroxide Wokha ndi Aluminide Wokhala ndi Aluminide Pakatikati, koma Ndipo kusamvana kwake kumatha kukwaniritsa zofunikira ngakhale popanda kusintha.

2. Mphamvu ya itorganic Flameants ogwiritsira ntchito utsi wotsika, phwi la Flame Flement Epdm EPDM ISTUTIT

Kugwiritsa ntchito kamodzi kwa magnesium hydroxide kapena aluminium hydroxide atornant Flamentant ndi magnernamu hydroxide Mh3005Z Mlingo wa magawo 120, ndikuwonjezeka kwa mh3005z, mphamvu ya annsile a EPDM yowonjezera zomata, katundu wa Flamentant adachuluka. Ndi kuwonjezeka kwa Mh3005Z, mescnions ku Viensni ndi Annsile Mphamvu ya Mphamvu ya EPDM Imbitsitsani Kumatira, Katundu Wamoto Wobwezeretsa Kuchuluka, ndipo Katundu Wosankhidwa wa Mphamvu Amatsika. Pamene chiwerengero cha ath 104E / mh3005Z ndi 90/30, okhazikika ndi lalattartant carties of Epdm akukwaniritsa zomatira. Kuyerekeza ath 104e / Mh3005Z ndi chiwerengero cha 110/10 ndi 120 / CREASS 20 Lath 24E / MH3005Z ndi chiwerengero cha 70/50 ndi 70/40 milandu ya Mh3005Z Ngakhale kuti katundu wosinthika wa MH3005Z sakwaniritsa zofunikira. Kuti muwonetsetsenso moto wobwezeretsanso, kuchuluka kwa moto sungathe kuchepetsedwa.

Mphamvu ya EPDM yopanda utsi yopanda utsi ndi 355 kapena apo, ndi kuchuluka kwa nthochi yodziwikiratu ndi kuchuluka kwa starm, ndipo sizingapangitse utsi, koma sizingachepetse utsi womwe watulutsidwa ndi mankhwala osokoneza bongo a rabara.

3. Utoto wochepetsa wothandizira

JB / T 10707 - 2007 'Bormoplastic Halogen-Flament Flamentard Rible Great Starday Montmoriltonite amakhala ndi calcium, sodium-yochokera ku Montmoriganonite, atavula ndikubalalika, kuyeretsa ndi kusinthana, mawonekedwe apadera a wosanjikizawo ndi ochepera 25 nm. Montmorillonite amasankhidwa kuti akwaniritse utsi wabwino.

Montmorilnorite pazinthu za mphira wa epdm zokhumba utsi zochulukitsa ndizodziwikiratu, komanso zitha kukhala zowonjezereka zocheperako zamoto, pomwe katundu wina samakhumudwitsa; Ndi kuwonjezeka kwa Monmorillonite, Epdm zokhumba za huble nthochi zimatsika pang'onopang'ono, ndipo amakonda kukhazikika, ndikuganizira zomwe mwapanga, sankhani kuchuluka kwa montmorigalonite kwa magawo 5.
