Ungakuthuthukisa Kanjani Ukuqhutshwa Kwe-Thermal Kwe-Nylon 6 Material?

Izici ezithonya ukuqhutshwa kokushisa kwento enayiloni 6 esimweni sezinto ezingaguquki nokumatanisa

Izici ezine:

• I-coefficient ye-thermal conductivity yezingcezu nezigcwalisi ze-nylon 6 base stock;

• Ukuhlakazeka kanye ne-bonding degree of fillers in inayiloni 6 matrix;

• Ukuma nokuqukethwe kokugcwalisa;

• Izici zokuhlanganisa esibonakalayo zokugcwalisa nenayiloni 6.

Ukuthuthukiswa kokusebenza okushisayo kwe-thermal conductive inayiloni 6 kungaqalwa kusuka ezicini ezine.

1. Ukusetshenziswa kwezingcezu nezigcwalisi zesitoko sesisekelo senayiloni 6 esinecoefficient ephezulu uma kuqhathaniswa ne-thermal conductivity.I-thermal conductivity yocezu lwenayiloni engu-6 emsulwa ngokuvamile isuka ku-0.244 iye ku-0.337W/MK, futhi inani layo lihlobene eduze ne-viscosity ehlobene ye-polymer, ukusatshalaliswa kwesisindo samangqamuzana nokuma kwe-molecule ye-polar.

Izihlungi ezisetshenziselwa ukuguqulwa kwe-non-insulator ye-thermal conductive inayiloni 6 zifaka i-aluminium, ithusi, i-magnesium nenye impushana yensimbi kanye ne-graphite ne-carbon fiber, njll. Uma iphezulu i-coefficient ye-thermal conductivity ye-powder yensimbi, kungcono ukuqhutshwa kwe-thermal. kuyinto.Kodwa-ke, uma kucatshangelwa izinga, izindleko kanye nokusebenza kokucubungula kwezinto ezihlukene ngokuphelele, i-aluminium powder ingcono kakhulu.Izigcwalisi ezisetshenziselwa ukuguqulwa kwe-insulator thermal conductive nylon 6 zihlanganisa i-alumina ne-magnesium oxide.I-Alumina ishibhile, isezingeni eliphezulu, futhi kulula ukuyicubungula, okwamukelwa amakhasimende amaningi.

2. Thuthukisa ukuma kokugcwalisaNgokugcwalisa okusetshenziselwa i-nylon 6 ye-thermal conductive, i-thermal conductivity ye-filler ingcono uma kunenzuzo kakhulu ekubunjweni kwendlela yokuhambisa ukushisa.I-oda elihlobene lithi Whisker > Fibrous > Flake > Granular.Uma kuncane usayizi wezinhlayiyana zokugcwalisa, ngcono ukuhlakazeka ku-matrix ye-nylon 6, kungcono ukuqhutshwa kwe-thermal.

3. Ukusetshenziswa kwezigcwalisi ezinokuqukethwe eduze nenani elibalulekileUma okuqukethwe kwe-thermal conductive plastic fillers ku-nylon 6 kuncane kakhulu, umphumela we-thermal conductivity awubonakali, futhi ingxenyenamba enkulu idlula i-40% ezimweni eziningi.Kodwa-ke, uma okuqukethwe kuphezulu kakhulu, izici zayo zokumaka zizokwehla kakhulu.Ezimweni eziningi, kunenani elibalulekile lokuqukethwe kwesigcwalisi ku-matrix yenayiloni 6, futhi ngaphansi kwaleli xabiso, izigcwalisi zizosebenzisana, ukuze kwakhiwe iketango lenethiwekhi yokuqhuba ukushisa okufana neketango inayiloni 6 matrix futhi ngaleyo ndlela andise conductivity ezishisayo.

4. Thuthukisa izici zokuhlanganisa isixhumi esibonakalayo phakathi kokugcwalisa ne-nayiloni 6 matrixUkuphakama kwedigri yenhlanganisela phakathi kwesigcwalisi kanye ne-nayiloni 6 matrix, kuba ngcono ukuqhutshwa kwe-thermal.Ukwelashwa okungaphezulu kwesigcwalisi ngesihlanganisi segraft ye-maleic anhydride efanelekile efanayo kanye ne-ejenti yokuhlanganisa kungathuthukisa izici zokusebenzelana phakathi kwenayiloni 6 nesigcwalisi, kanye ne-thermal conductivity coefficient ye-thermal conductive inayiloni 6 impahla ingakhuphuka ngo-10% iye ku-20. %.
