Kukumana ndi Mphamvu Yaikulu, Kutaya Magazi, Kapena Kuyenda Mosauka mu Ma Cable Compounds a LSZH?
Zipangizo za chingwe zopanda utsi wochepa (LSZH) zikufunikira kwambiri kuti chingwecho chikhale chotetezeka komanso chokhazikika. Komabe, kukwaniritsa kukonzedwa bwino kwambiri kukupitirirabe kukhala kovuta. Kugwiritsa ntchito kwambiri zinthu zodzaza moto monga aluminium hydroxide (ATH) ndi magnesium hydroxide (MDH)—nthawi zambiri kumayambitsa kusayenda bwino kwa madzi, mphamvu yayikulu, kutha kwa malo ouma, komanso kuuma kwa madzi panthawi yotulutsa.

Chifukwa chiyani ma LSZH Cable Compounds ndi ovuta kuwakonza？

Zinthu zomwe zimapanga waya ndi chingwe choletsa moto chopanda utsi wambiri ndi zakuti zinthu zonse zilibe halogen, ndipo utsi wochepa kwambiri umatuluka panthawi yoyaka. Pofuna kukwaniritsa zinthu ziwiri zofunikazi, zinthu zambiri zoletsa moto zinawonjezedwa pakupanga, zomwe zimayambitsa mavuto ambiri okhudzana ndi kukonza.

Zotsatirazi ndi zizindikiro zodziwika bwino za mankhwala a chingwe opanda utsi wambiri a halogen:

1. Chifukwa cha kuchuluka kwa zinthu zodzaza moto monga aluminiyamu hydroxide ndi magnesium hydroxide zomwe zawonjezeredwa, zomwe zimapangitsa kuti kuyenda bwino kwa madzi kusamayende bwino, komanso kutentha komwe kumachitika chifukwa cha kutentha kumakwera, zomwe zimapangitsa kuti aluminiyamu hydroxide ndi magnesium hydroxide ziwonongeke.

2. Kuchepa kwa ntchito yotulutsa mpweya, komanso liwiro lotulutsa mpweya kwambiri, mphamvu yotulutsa mpweyayo sinasinthe.

3. Chifukwa cha kusagwirizana bwino kwa ma polyolefin ndi ma retardants amoto ndi ma filler ena, zomwe zimapangitsa kuti pasakhale kufalikira bwino panthawi yokonza ndi kuchepa kwa mphamvu zamakanika.

4. Kufalikira kosagwirizana kwa zinthu zoletsa moto zomwe sizili zachilengedwe m'dongosolo kumabweretsa malo owuma komanso kusowa kwa kuwala panthawi yotulutsa.

5. Kugawanika kwa kapangidwe ka zinthu zoletsa moto ndi zina zodzaza kumapangitsa kuti kusungunuka kumamatire ku mutu wa die, kuchedwetsa kuchotsedwa kwa zinthu, kapena kuchepa kwa mamolekyulu omwe amapangidwa, zomwe zimapangitsa kuti zinthu zisonkhanitsidwe pakamwa pa die, motero zimakhudza ubwino wa chingwecho.

Kodi mungathetse bwanji mavuto a njirazi ndi khalidwe la pamwamba pa chingwe cha LSZH?

Kuti tithetse mavuto awa,ukadaulo wa silicone masterbatchyakhala njira yodalirika mu mapangidwe a LSZH compound, ikukweza magwiridwe antchito a processing komanso magwiridwe antchito a pamwamba popanda kuwononga mphamvu zamakanika kapena zamagetsi.

Chifukwa chiyanisilicone masterbatch ndi njira yothandiza kwambirikuti ziwongolere kukonza ndi kugwira ntchito bwino kwa ma LSZH cable compounds?

Silikoni masterbatch ndi mtundu wachowonjezera chogwira ntchitondi ma thermoplastics osiyanasiyana ngati zonyamulira ndi polysiloxane ngati ziwalo zogwirira ntchito. Kumbali imodzi, masterbatch yochokera ku silicone imatha kukonza mphamvu ya kayendedwe ka thermoplastic system panthawi yosungunuka, kufalitsa bwino ma fillers, kuchepetsa kugwiritsa ntchito mphamvu ya extrusion ndi jekeseni, ndikuwonjezera magwiridwe antchito opanga; Kumbali ina, chithandizo chopangira zinthu chochokera ku Silicone ichi chingathandizenso kukonza bwino pamwamba pa zinthu zomaliza zapulasitiki, kuchepetsa kukwera kwa pamwamba ndikuwonjezera kukana kwa kuwonongeka ndi kukanda. Kuphatikiza apo, monga chithandizo chopangira zinthu zamakampani opanga ma thermoplastic, silicone masterbatch imatha kusintha bwino ndi kuchuluka kochepa (<5%), popanda kuganizira kwambiri momwe imagwirira ntchito ndi zinthu za matrix.

Kodi munthu angasankhe bwanji bwino wopanga silicone masterbatch woyenera kuti athetse mavuto okhudzana ndi njira yopangira komanso ubwino wa pamwamba pa zingwe zopanda utsi wambiri komanso zopanda halogen (LSZH)?

Chengdu Silike Technology Co., Ltd. ndi kampani yotsogola kwambiri yaku China yomwe imadziwika bwino ndizowonjezera zopangidwa ndi silikonikwa mafakitale a pulasitiki ndi rabara. Ndi kafukufuku wodzipereka wa zaka zoposa 20 wokhudzana ndi kuphatikiza kwa silicone ndi ma polima, Silike yadzikhazikitsa yokha ngati mnzawo watsopano komanso wodalirika wa mayankho owonjezera ogwira ntchito bwino.

Pofuna kuthandiza opanga kuthana ndi mavuto opanga okhudzana ndi zingwe za LSZH, Silike yapanga mndandanda wathunthu wazowonjezera za pulasitiki za siliconeZopangidwa makamaka kuti ziwongolere kukonza kwa zinthu za chingwe. Zinthu zodziwika bwino, monga Silicone Masterbatch LYSI-401 ndi Silicone Masterbatch LYSI-502C, zimapereka mayankho ogwira mtima omwe cholinga chake ndi kukonza bwino ntchito ndi ubwino wa pamwamba, motero zimathandiza kuti ntchito ya waya ndi chingwe ikhale yabwino kwambiri.

Ubwino wa Kuchita Bwino: Zotsatira Zachizolowezi za Mayeso a Silicone Masterbatch mu LSZH Cable Compounds

Kuwonjezera SILIKESilikoni Masterbatch (Siloxane Masterbatch) mndandanda wa LYSIKudzera mu makina odzaza ndi utsi wochepa wa halogen opanda utsi, chingwecho chimatha kusintha kusinthasintha kwa ntchito, kuchepetsa mphamvu, komanso kukonza bwino ntchito. Chithunzi 1 chikuwonetsa kuyerekeza kwa magwiridwe antchito a chingwecho mutawonjezera 1%LYSI-401 silicone masterbatchmu fomula ya kampani yathu yoyeserera yopanda utsi wambiri (Table 1). Zitha kuwoneka kuti magwiridwe antchito oyenera awonjezeka kwambiri.

Chithunzi 2, Chithunzi 3, ndi Chithunzi 4 zikuwonetsa mayeso a torque rheometer a siloxane High ContentSilikoni masterbatch LYSI-502Cyowonjezeredwa ku fomula yodziwika bwino yopanda utsi wambiri komanso kuyerekeza ndi mphamvu, kupanikizika, ndi kukhuthala kwa zinthu zakunja zomwe zimapikisana nazo. Zitha kuwoneka kuti LYSI-502C ili ndi ntchito yabwino kwambiri yopaka mafuta.

Chithunzi 5 chikuwonetsa kufunika kwa kusonkhanitsa zinthu mkati mwa chingwe chotulutsira chingwe pambuyo powonjezera silicone masterbatch. Zotsatira zake zikuwonetsa kuti kuphatikiza silicone masterbatch yokhazikika kumachepetsa kwambiri kuchuluka kwa ma die. Kuphatikiza apo, SILIKE'smkulu molekyulu kulemera silikoni masterbatchimasonyeza bwino kwambiri zotsatira zake pochepetsa kuchuluka kwa ma die buildup, zomwe zikusonyeza kuthekera kwake kowonjezera magwiridwe antchito.

Chidule:Siloxane imapezeka mu standardma masterbatches a silikonisiili ndi polar, zomwe zingayambitse mavuto chifukwa cha kusiyana kwa magawo a kusungunuka kwa ma polima ambiri a carbon chain. Ngati kuwonjezerako kuli kochulukirapo, kungayambitse mavuto monga kutsetsereka kwa screw, mafuta ochulukirapo, kugawanika kwa pamwamba pa chinthucho, kugwira ntchito kosagwirizana, komanso kufalikira kosagwirizana mkati mwa substrate.

Pofuna kuthana ndi mavutowa, SILIKE yapanga njira zingapo zothanirana ndi mavutowa.zowonjezera za silicone zolemera kwambiri zamamolekyuluzomwe zasinthidwa ndi magulu apadera ogwira ntchito. Izizowonjezera zopangira polima zopangidwa ndi siliconeZapangidwa kuti zikwaniritse zofunikira zinazake zogwiritsidwa ntchito m'machitidwe osiyanasiyana a thermoplastic. Pogwira ntchito ngati zomangira mkati mwa substrate, zimathandizira kuti zigwirizane, zimafalitsa bwino, komanso zimalimbitsa kumamatira. Izi zimapangitsa kuti ntchito yonse ya substrate ikhale yabwino kwambiri. M'machitidwe opanda utsi wambiri komanso opanda halogen, zowonjezera zatsopanozi zimaletsa kutsetsereka kwa screw ndi kuchepetsa kwambiri kuchulukana kwa zinthu zomwe zimawonongeka.

Kodi mukufunafunachowonjezera chopangira polimakuti muwongolere njira yanu yopangira chingwe cha LSZH?
Onani momwe mayankho a masterbatch ochokera ku silicone a SILIKE, kuphatikizapo LYSI-401 yowonjezera ya silicone ndi siloxane masterbatch LYSI-502C, angakuthandizireni kukonza zokolola, kuchepetsa kukonza die, komanso kukwaniritsa mtundu wapamwamba wa chingwe. Tikukupemphani kuti mulumikizane nafe kuti mudziwe zambiri komanso kuti mupemphe chitsanzo.
