Momwe mungathetsere zowawa zazitsulo zopanda utsi za halogen zopanda utsi?

LSZH imayimira ma halojeni a utsi wochepa, opanda utsi wopanda halojeni, chingwe chamtunduwu ndi waya zimatulutsa utsi wochepa kwambiri ndipo sizitulutsa ma halojeni apoizoni zikamatenthedwa. Komabe, Kuti mukwaniritse zinthu ziwiri zofunika kwambiri, popanga zida zachitsulo zopanda utsi wopanda utsi, ma halogens a Low-smoke zero halogens (LSZH) amadzaza kwambiri, zomwe zimatsogoleranso mwachindunji kumakina & kukonza katundu.

Zovuta pakukonza zinthu zopanda utsi wopanda halogen:

1. Nthawi zonse chilinganizo, LLDPE/EVA/ATH mkulu zili wodzazidwa LSZH polyolefin chingwe mankhwala mankhwala ali mpaka 55-70% ATH/MDH, Monga ambiri a aluminiyamu hydroxide, magnesium hydroxide, ndi zina retardants lawi kuti agwirizane ntchito dongosolo. kusuntha kumakhala koyipa, kutulutsa kutentha kokangana pakukonza kumabweretsa kutentha komwe kumayambitsa kuwonongeka kwa aluminiyamu ndi magnesium hydroxide.

2. Low extrusion dzuwa, ngakhale inu kuonjezera liwiro la extrusion voliyumu amakhalabe chimodzimodzi.

3. Kusagwirizana koyipa kwa inorganic flame retardants ndi fillers ndi polyolefins, kubalalitsidwa moyipa panthawi yokonza, zomwe zimapangitsa kuti mawotchi achepetse.

4. Moukali pamwamba ndi kusowa gloss pa extrusion chifukwa chosiyana kubalalitsidwa kwa inorganic flame retardants mu dongosolo.

5.Mapangidwe a polarity a retardants ndi zodzaza moto zimapangitsa kusungunuka kumamatira kumutu wa nkhungu, kuchedwetsa kutulutsidwa kwa zinthuzo kuchokera mu nkhungu, kapena mamolekyu ang'onoang'ono omwe amapangidwawo amatuluka, zomwe zimapangitsa kuti zinthu zambiri zitheke potsegula nkhungu, motero zimakhudza ubwino wa chingwe.

Kutengera ndi zomwe zili pamwambazi, SILIKE yapanga mndandanda wasilicon yowonjezeramankhwala opangidwa makamaka kuti athe kuthana ndi zowawa za kukonza ndi kumtunda kwa chingwe chopanda utsi cha halogen wopanda utsi, utsi wotsika zero zero halogens waya&chingwe mankhwala, kapena mankhwala ena odzaza mchere a Polyolefin opangira mawaya ndi zingwe, kupereka mayankho ogwira mtima osiyanasiyana. ku zovuta izi.

Mwachitsanzo:Silicone Masterbatch (Siloxane Masterbatch) LYSI-401ndi mawonekedwe a pelletized ndi 50% ultra-high molecular weight siloxane polima omwazikana mu low-density polyethylene (LDPE). Amagwiritsidwa ntchito kwambiri ngati chowonjezera chothandizira pamakina opangira utomoni wa PE kuti apititse patsogolo zinthu zogwirira ntchito ndikusintha mawonekedwe apamwamba.

Kuwonjezera 0.5-2% yaSILIKE silikoni masterbatch LYSI-401Kumakina odzaza ndi utsi wochepa wa utsi wa halogen wopanda waya & zingwe kapena utsi wotsika zero halogens (LSZH) zingwe zimathandizira mawaya ndi opanga zingwe kuti azichulukirachulukira, amatha kupititsa patsogolo kusungunuka kwamadzi, kuchepetsa torque, kuthamanga kwa mzere wothamanga popanda chilichonse. kusamuka, kusintha khalidwe pamwamba pa waya ndi chingwe komanso, (Lower coefficient ya mikangano, zikande bwino ndi kuvala kukana, kutsika kwabwinoko, komanso kumva m'manja ...) osalipira ndalama zambiri pazowonjezera zosafunikira.

Kawirikawiri, kwa Wambasilicone masterbatch, siloxane si polar, ndipo ambiri a carbon unyolo polima solubility magawo a kusiyana ndi lalikulu kwambiri, Kuwonjezera chiwerengero chachikulu cha milandu kungachititse kuti processing slippage wononga, kudzoza kwambiri, pamwamba pa mankhwala delamination, zimakhudza pamwamba pa zinthu za kugwirizana katundu wa mankhwala mu gawo lapansi omwazika mosagwirizana ndi zina zotero.

Pamene,SILIKE's ultra-high molecular weight silikoni zowonjezeraamasinthidwa ndi magulu apadera, omwe amatha kusankhidwa ndikufananizidwa ndi zosowa zosiyanasiyana za zowonjezera za silicone m'magulu osiyanasiyana. Mndandanda wazinthuzi ukhoza kugwira ntchito yokhazikika mu gawo lapansi, motero kugwirizana bwino ndi gawo lapansi, kubalalitsidwa kosavuta, kugwirizanitsa mwamphamvu, motero kumapatsa gawo lapansi ntchito yabwino kwambiri. Ikagwiritsidwa ntchito m'makina a LZSH ndi HFFR, imatha kupewa kutsetsereka komanso imatha kutenga gawo lalikulu pakuwongolera kuchuluka kwa zinthu mkamwa.
