Lintlha tse susumetsang conductivity ea mocheso oa thepa ea nylon 6 tabeng ea thepa e tsitsitseng le e tšoanang.
Lintlha tse 'nè:
-
Thermal conductivity coefficient ea lilae le li-filler tsa nylon 6 base stock;
-
Disperity le bonding degree of fillers in nylon 6 matrix;
-
Sebopeho le litaba tsa li-fillers;
-
Litšobotsi tsa khokahano ea khokahano ea li-filler le nylon 6.
Ntlafatso ea conductivity ea mocheso oa thepa ea nylon 6 ea mocheso e ka qalisoa ho tsoa likarolong tse 'nè.
1. Tšebeliso ea lilae le li-filler tsa nylon 6 base stock e nang le coefficient e batlang e le e phahameng ea mocheso oa mocheso.Thermal conductivity ea pure nylon 6 slice ka kakaretso e tloha 0.244 ho 0.337W / MK, 'me boleng ba eona bo amana haufi-ufi le viscosity e amanang le polymer, kabo ea boima ba limolek'hule le ho shebana ha molek'hule ea polar.
Li-fillers tse sebelisetsoang ho fetola nylon 6 e se nang insulator ea mocheso li kenyelletsa aluminium, koporo, magnesium le phofo e 'ngoe ea tšepe hammoho le graphite le carbon fiber, joalo-joalo. ke.Leha ho le joalo, ha ho nahanoa ka boleng, litšenyehelo le ts'ebetso ea ts'ebetso ea lisebelisoa tse fapaneng ka ho feletseng, phofo ea aluminium e molemo haholo.Fillers tse sebelisetsoang ho fetola insulator thermal conductive nylon 6 li kenyelletsa alumina le magnesium oxide.Alumina e theko e tlaase, ea boleng bo holimo, 'me e bonolo ho e sebetsa, e amoheloang ke bareki ba bangata.
2. Ntlafatsa sebopeho sa ho tlatsaBakeng sa filler e sebelisitsoeng ho thermal conductive nylon 6 material, thermal conductivity of filler e molemo haeba e le molemo ho theha tsela ea ho tsamaisa mocheso.Taelo e lekanyelitsoeng ke Whisker > Fibrous > Flake > Granular.E nyenyane boholo ba likaroloana tsa ho tlatsa, ho molemo ho senyeha ha matrix a nylon 6, ho ntlafatsa mocheso oa mocheso.
3. Tšebeliso ea li-filler tse nang le litaba tse haufi le boleng ba bohlokoaHaeba litaba tsa li-plastics tsa thermally conductive fillers ka nylon 6 li le nyane haholo, phello ea conductivity ea mocheso ha e hlake, 'me karoloana ea boima e feta 40% maemong a mangata.Leha ho le joalo, haeba litaba li phahame haholo, thepa ea eona ea mechine e tla fokotseha haholo.Maemong a mangata, ho na le boleng ba bohlokoa bakeng sa likahare tsa ho tlatsa ka har'a matrix a nylon 6, 'me tlas'a boleng bona, li-fillers li tla sebelisana, e le hore li thehe letlooeng kapa ketane e kang mocheso oa mocheso oa marang-rang. nylon 6 matrix 'me kahoo eketsa conductivity ea mocheso.
4. Ntlafatsa litšoaneleho tsa bonding tsa interface lipakeng tsa filler le nylon 6 matrixHa tekanyo ea ho kopana e phahame pakeng tsa ho tlatsa le matrix ea nylon 6, ho etsa hore mocheso o be le mocheso o betere.Phekolo e holim'a filler e nang le compatilizer e ts'oanang ea maleic anhydride graft le moemeli ea kopanyang e ka ntlafatsa sebopeho sa sebopeho lipakeng tsa nylon 6 le setlamo, 'me coefficient ea conductivity ea mocheso oa thepa ea nylon 6 e ka eketsoa ka 10% ho isa ho 20. %.
