Ukuphucula njani ukuPhathwa kweThermal yeNylon 6 Material?

Izinto ezichaphazela ukuqhutyelwa kwe-thermal ye-nylon 6 kwizinto eziphathekayo kwimeko yezinto ezisisigxina kunye nokuhambelana.

Izinto ezine:

• I-coefficient ye-Thermal conductivity yezilayi kunye nokuzaliswa kwe-nylon 6 isiseko sesiseko;

• I-Disperity kunye ne-bonding degree of fillers kwi-nylon 6 matrix;

• Ubume kunye nomxholo weefayili;

• Iimpawu zokudityaniswa kojongano lwezihluzi kunye nenayiloni 6.

Ukuphuculwa kwe-thermal conductivity ye-thermal conductive nylon 6 impahla inokuqaliswa kwiinkalo ezine.

1. Ukusetyenziswa kwezilayi kunye nokuzaliswa kwe-nylon 6 isiseko sesitokisi esine-coefficient ephezulu ye-thermal conductivity.I-thermal conductivity ye-nylon ecocekileyo ye-6 slice ngokubanzi ukusuka kwi-0.244 ukuya kwi-0.337W / MK, kwaye ixabiso layo lihambelana ngokusondeleyo ne-viscosity ehambelanayo ye-polymer, ukusabalalisa ubunzima be-molecular kunye nokuqhelaniswa kwe-molecule ye-polar.

Izigcwalisi ezisetyenziselwa ukuguqulwa kwe-non-insulator ye-nayiloni ye-thermal conductive 6 ibandakanya i-aluminium, ithusi, i-magnesium kunye nolunye umgubo wesinyithi kunye negraphite kunye ne-carbon fiber, njl. yi.Nangona kunjalo, ngokuqwalasela umgangatho, iindleko kunye nokusebenza kokusebenza kwezinto ezahlukeneyo ngokubanzi, i-aluminium powder ithandwa kakhulu.Iifayile ezisetyenziselwa ukuguqulwa kwe-insulator thermal conductive nylon 6 ziquka i-alumina kunye ne-magnesium oxide.I-alumina inexabiso eliphantsi, ikumgangatho ophezulu, kwaye kulula ukuyiqhuba, eyamkelwa ngabathengi abaninzi.

2. Phucula imilo yokuzalisaKwi-filler esetyenziswe kwi-thermal conductive nylon 6, i-thermal conductivity ye-filler ingcono ukuba inenzuzo ngakumbi ekubunjweni kwendlela yokuqhuba i-thermal.Ulungelelwaniso olunxulumeneyo yiWhisker > Fibrous > Flake > Granular.Ubuncinci ubungakanani be-particle ye-filler, bhetele ukusabalalisa kwi-nylon 6 matrix, ngcono i-thermal conductivity.

3. Ukusetyenziswa kweefayili ezinomxholo okufutshane nexabiso elibalulekileyoUkuba umxholo we-thermal conductive plastic fillers kwi-nylon 6 incinci kakhulu, i-thermal conductivity effect ayibonakali, kwaye i-mass fraction idlula i-40% kwiimeko ezininzi.Nangona kunjalo, ukuba umxholo uphezulu kakhulu, iipropathi zoomatshini ziya kuncipha kakhulu.Kwiimeko ezininzi, kukho ixabiso elibalulekileyo kumxholo wokugcwalisa kwi-nayiloni ye-6 matrix, kwaye phantsi kweli xabiso, izigcwalisi ziya kusebenzisana omnye nomnye, ukwenzela ukuba zenze i-mesh okanye i-chain-like chain conduction network network chain. inayiloni 6 matrix kwaye ngaloo ndlela ukwandisa conductivity thermal.

4. Ukuphucula iimpawu zokudityaniswa kojongano phakathi kokuzalisa kunye nenylon 6 matrixUkuphakama kweqondo lokudityaniswa phakathi kwe-filler kunye ne-nylon 6 matrix, ngcono ukuhanjiswa kwe-thermal.Unyango olungaphezulu kwi-filler kunye ne-maleic anhydride graft compatilizer efanelekileyo efanayo kunye ne-arhente yokudibanisa inokuphucula iimpawu ze-interface phakathi kwe-nayiloni 6 kunye ne-filler, kunye ne-coefficient ye-thermal conductivity ye-thermal conductive nylon 6 impahla inokunyuswa nge-10% ukuya kwi-20. %.
