Faa'iidooyinka kuleyliyaha kulaylka leh magnesium oxide

Dareenka kulaylka waxaa si isku mid ah uga buuxsamay walxo matrix kuleyl ah iyadoo la isticmaalayo kuleylka kuleylka si loo hagaajiyo kuleylka kuleylka.Waxqabadka kulaylka waxaa inta badan lagu cabbiraa kuleyliyaha kuleylka (cutub: W/mk).Daawaynta kulaylka waxa loo qaybiyaa balaastiig hadhaaga kulaylka iyo caaga dahaarka kulaylka.Qaybaha ugu muhiimsan ee kulaylka kuleylka waxaa ka mid ah walxaha substrate-ka iyo buuxinta, iyo walxaha substrate-ka waxaa ka mid ah PPS, PA6/PA66, LCP, TPE, PC, PPA, PEEK, iwm.;Budada kaarboon kulaylka sareeyo, iwm.

Balaastikada kulaylka leh waxay leedahay sifooyinka soo socda:
(1) Kala daadinta kulaylka lebbiska ah, ka fogow meelaha gubanaya, yaraynta qallafsanaanta maxalliga ah ee ay keento heerkulka sare sababtoo ah heerkulka sare;
(2) Miisaanka fudud, 40-50% ka fudud aluminium;
(3) Way ku habboon tahay samaynta iyo ka-hortagga, ma jirto habayn labaad;
(4) Heerka sare ee naqshadeynta alaabta;

Sababtoo ah habka wax-soo-saarka ayaa inta badan ah wax-qabashada, caaggu wuxuu ku qulqulayaa caaryada ka dib kuleylka, ka dibna la qaboojiyo.Astaamaha habka wax-soo-saarka ayaa ka dhigaya isku-dhafka kuleylka ee walxaha muujinaya sifooyinka jinsiga ka soo horjeeda, taas oo ah jihada qulqulka xabagta inta lagu jiro duritaanka iyo jihada qulqulka qulqulka tooska ah.Guud ahaan, heerkulka kulaylka ee jihada qulqulka xabagta waa 3-6 jeer marka loo eego kuleylka kuleylka ee jihada qulqulaya ee caag toosan.Kala duwanaanshiyahan waxaa sababa qaabeynta la isku duro ee caagga marka ay si fudud u sameysanto jihada socodka.

Nadiifinta sare ee oxide magnesium, caddaan wanaagsan, granularity yar yar iyo lebis, iyo baahinta wanaagsan, waxaa loo isticmaali karaa conductivity kulaylka filimka silicon kulaylka, conductivity kaamerada (PA6, PP, PPS, ABS), iwm Qadarka gaari karaa 70- Qaybaha 80, iyo heerka ugu sarreeya ee kulaylku wuxuu gaari karaa 5W / mk Natiijooyinku waxay muujinayaan in marka xaddiga magnesium oxide uu ka yar yahay qaybaha 200, hagida kulaylka iyo xoogga xajinta ee cabbirka walxaha yar yar ee magnesium oxide buuxinta caag silikoon ayaa ka weyn kan weyn. Cabbirka walxaha magnesium oxide, halka heerka fidintu uu ka soo horjeedo;cabbirka walxaha waaweyni waa ka soo horjeeda;xajmiga qaybta weyn;Magnesium oxide/xajmiga qayb yar oo magnesium oxide ah iyo saamiga isticmaalka caag silikoon ee 100/100 waa tan ugu weyn;ku darida qadar ku haboon ee wakiilka isku xirka silane waxay ku haboon tahay kordhinta hagida kulaylka ee caag silikoon.Qadarka magnesium waa 0.5%.Gudaha PA, PP, PES, ku dar 40-50% magnesium oxide, taas oo si weyn u wanaajin karta kulaylka caagga ah.
