Ubwino wa matenthedwe madutsidwe ndi magnesium okusayidi

Thermal conductivity imadzazidwa mofanana ndi zinthu zotentha za matrix pogwiritsa ntchito matenthedwe amtundu kuti apititse patsogolo kayendetsedwe kake ka kutentha.Kutentha kwapang'onopang'ono kumayesedwa makamaka ndi kutentha kwapakati (gawo: W / mk).Matenthedwe madutsidwe amagawidwa kutentha conductive pulasitiki ndi matenthedwe kutchinjiriza pulasitiki.Zigawo zazikulu za matenthedwe matenthedwe zimaphatikizapo zida zam'munsi ndi zodzaza, ndipo zida zam'munsi zimaphatikizapo PPS, PA6/PA66, LCP, TPE, PC, PPA, PEEK, etc.;High-kutentha mpweya ufa, etc.

Thermal conductive pulasitiki ili ndi izi:
(1) Kutentha kwamtundu umodzi, kupewa mawanga oyaka, kuchepetsa mapindikidwe am'deralo chifukwa cha kutentha kwambiri chifukwa cha kutentha kwambiri;
(2) Kulemera kopepuka, 40-50% kupepuka kuposa aluminiyamu;
(3) Ndi yabwino akamaumba ndi processing, palibe processing yachiwiri;
(4) Mlingo wapamwamba wa kapangidwe kazinthu;

Chifukwa njira yopangirayo imakhala yowumba, mphira umalowa mu nkhungu pambuyo potentha, kenako utakhazikika.Makhalidwe a ndondomekoyi amachititsa kutentha kwa zinthu zomwe zimasonyeza makhalidwe a amuna kapena akazi okhaokha, ndiko komwe kumayenda kwa guluu panthawi ya jekeseni ndi kayendetsedwe ka guluu wowongoka.Nthawi zambiri, kutenthetsa kwamafuta komwe kumayendera guluu kumakhala nthawi 3-6 kuposa momwe matenthedwe amatenthetsera komwe kumayendera mphira wowongoka.Kusiyanaku kumayamba chifukwa cha jekeseni wopangira mphira pamene amapangidwa mosavuta mumayendedwe oyenda.

High -kuyera kwa magnesium okusayidi, whiteness wabwino, granularity yaing'ono ndi chifanane, ndi decentralization wabwino, angagwiritsidwe ntchito matenthedwe madutsidwe wa matenthedwe pakachitsulo filimu, matenthedwe madutsidwe (PA6, PP, PPS, ABS), etc. The kuchuluka akhoza kufika 70- Zigawo 80, komanso kutentha kwakukulu kumatha kufika 5W/mk Zotsatira zikuwonetsa kuti kuchuluka kwa magnesium oxide kumakhala kochepera 200, chiwongolero chamafuta ndi kulimba kwa tinthu tating'onoting'ono ta magnesium oxide kudzaza mphira wa silicon ndi wamkulu kuposa wamkulu. kukula kwa tinthu ta magnesium okusayidi, pomwe kuchuluka kwa kutambasula ndikosiyana;kukula kwakukulu kwa tinthu ndikosiyana;chachikulu tinthu kukula;Magnesium okusayidi / yaying'ono tinthu kukula magnesium okusayidi ndi ntchito chiŵerengero cha mphira pakachitsulo pa 100/100 ndi yaikulu;kuwonjezera kuchuluka koyenera kwa silane coupling agent ndikoyenera kukulitsa chitsogozo chamafuta a rabara ya silicon.Kuchuluka kwa magnesium ndi 0.5%.Mu PA, PP, PES, onjezani 40-50% magnesium oxide, yomwe imatha kusintha kwambiri matenthedwe apulasitiki.
