Momwe Mungakulitsire Matenthedwe Otentha a Nylon 6 Material?

Zomwe zimathandizira kutenthetsa kwazinthu za nayiloni 6 pakakhala zinthu zokhazikika komanso zofananira.

Zinthu zinayi:

• Thermal conductivity coefficient of slices and fillers of nayiloni 6 base stock;

• Disperity ndi kugwirizana digiri ya fillers mu nayiloni 6 masanjidwewo;

• Mawonekedwe ndi zomwe zili mu fillers;

• Mawonekedwe olumikizana ndi ma fillers ndi nayiloni 6.

Kusintha kwa matenthedwe matenthedwe azinthu zotenthetsera za nayiloni 6 zitha kuyambika kuchokera kuzinthu zinayi.

1. Kugwiritsa ntchito magawo ndi zomangira za nayiloni 6 zoyambira zokhala ndi machulukidwe apamwamba kwambiri amafuta.Kutentha kwapang'onopang'ono kwa kagawo kakang'ono ka nayiloni 6 nthawi zambiri kumachokera ku 0.244 mpaka 0.337W/MK, ndipo mtengo wake umagwirizana kwambiri ndi kukhuthala kwa polima, kugawa kwa kulemera kwa mamolekyu ndi kutengera kwa molekyulu ya polar.

Zodzaza zomwe zimagwiritsidwa ntchito pakusintha kwa nayiloni 6 yomwe si insulator yotentha imaphatikizapo aluminiyamu, mkuwa, magnesium ndi zitsulo zina zachitsulo komanso graphite ndi carbon fiber, ndi zina zotero. Kukwera kwapamwamba kwa matenthedwe amtundu wa chitsulo ufa ndiko, kumapangitsanso kutentha kwabwino. ndi.Komabe, poganizira za khalidwe, mtengo ndi kukonza ntchito za zipangizo zosiyanasiyana momveka bwino, ufa wa aluminiyamu ndi wabwino kwambiri.Zodzaza zomwe zimagwiritsidwa ntchito posintha insulator matenthedwe conductive nylon 6 zimaphatikizapo alumina ndi magnesium oxide.Alumina ndi yotsika mtengo, yapamwamba kwambiri, komanso yosavuta kukonza, yomwe imavomerezedwa ndi makasitomala ambiri.

2. Sinthani mawonekedwe a fillerPakuti filler ntchito matenthedwe conductive nayiloni 6 zakuthupi, matenthedwe conductivity wa filler bwino ngati n'kopindulitsa kwambiri mapangidwe matenthedwe conduction njira.Dongosolo lachibale ndi Whisker> Fibrous> Flake> Granular.Zing'onozing'ono kukula kwa tinthu za filler, bwino disperity mu nayiloni 6 masanjidwewo, ndi bwino matenthedwe madutsidwe.

3. Kugwiritsa ntchito zodzaza ndi zomwe zili pafupi ndi mtengo wofunikiraNgati zili ndi thermally conductive mapulasitiki fillers mu nayiloni 6 ndi laling'ono kwambiri, matenthedwe madutsidwe zotsatira si zoonekeratu, ndi misa kachigawo kuposa 40% nthawi zambiri.Komabe, ngati zomwe zili pamwambazi ndizokwera kwambiri, zimango zake zimachepa kwambiri.Nthawi zambiri, pamakhala phindu lofunika kwambiri pazomwe zimadzaza mu nayiloni 6 masanjidwewo, ndipo pansi pa mtengo uwu, zodzazazo zimalumikizana wina ndi mnzake, kuti apange mauna kapena unyolo ngati unyolo wowongolera kutentha kwaukonde mu nayiloni 6 masanjidwewo motero kuonjezera matenthedwe madutsidwe.

4. Sinthani mawonekedwe olumikizirana pakati pa chodzaza ndi nayiloni 6 matrixKukwera kwa kuchuluka kwa kuphatikiza pakati pa chodzaza ndi nayiloni 6 matrix, kumapangitsa kuti matenthedwe azitha bwino.The mankhwala pamwamba pa filler ndi yoyenera maleic anhydride kumezanitsa compatilizer ndi kugwirizana wothandizira akhoza kusintha mawonekedwe mawonekedwe pakati nayiloni 6 ndi filler, ndi matenthedwe madutsidwe coefficient wa matenthedwe conductive nayiloni 6 zakuthupi akhoza ziwonjezeke ndi 10% mpaka 20 %.
