Maitiro eKuvandudza Thermal Conductivity yeNylon 6 Material?

Izvo zvinhu zvinopesvedzera thermal conductivity yenylon 6 zvinhu munyaya yezvakagadziriswa zvinhu uye zvinoenderana.

Zvinhu zvina:

• Thermal conductivity coefficient yezvidimbu uye mafirita enylon 6 base stock;

• Disperity uye bonding degree remafirita munylon 6 matrix;

• Chimiro uye zviri mukati mekuzadza;

• Iyo interface yekubatanidza maitiro ekuzadza uye nylon 6.

Iko kuvandudzwa kwekupisa kwekupisa kweiyo thermal conductive nylon 6 zvinhu zvinogona kutangwa kubva pazvikamu zvina.

1. Kushandiswa kwezvimedu uye mafirita enylon 6 base stock ine yakawedzera kupisa yekupisa conductivity coefficient.Iyo yekupisa conductivity yeyakachena nylon 6 slice inowanzo kubva 0.244 kusvika 0.337W/MK, uye kukosha kwayo kunodyidzana nehukama viscosity yepolymer, kugovera kwemamorekuru uye kutaridzika kwepolar molecule.

Mafirita anoshandiswa kugadziridza asiri-isulator thermal conductive naironi 6 anosanganisira aruminiyamu, mhangura, magnesium uye imwe simbi poda pamwe negraphite uye kabhoni faibha, etc. Iyo yakakwirira yekupisa conductivity coefficient yesimbi poda ndeye, zviri nani thermal conductivity. ndizvo.Zvisinei, tichifunga nezvehutano, mari uye kushandiswa kwekushanda kwezvinhu zvakasiyana-siyana zvakakwana, aluminium poda inonyanya kudiwa.Mafirita anoshandiswa pakugadzirisa insulator thermal conductive nylon 6 anosanganisira alumina uye magnesium oxide.Alumina yakachipa, yepamusoro-soro, uye iri nyore kugadzirisa, iyo inogamuchirwa nevatengi vakawanda.

2. Kuvandudza chimiro chekuzadzaKune iyo inozadza inoshandiswa mune thermal conductive nylon 6 zvinhu, iyo thermal conductivity yemuzadziri iri nani kana ichinyanya kubatsira pakuumbwa kweiyo thermal conduction nzira.Iyo yehukama order ndeye Whisker> Fibrous> Flake> Granular.Iyo diki iyo particle size yekuzadza, zviri nani kupararira munylon 6 matrix, zviri nani kudziya kwekushisa.

3. Kushandiswa kwemafuta ane zvinyorwa zviri pedyo nekukosha kwakakoshaKana zviri mukati me thermally conductive plastics fillers munylon 6 idiki zvakanyanya, thermal conductivity effect haisi pachena, uye chikamu chehuwandu chinodarika 40% muzviitiko zvakawanda.Nekudaro, kana zvirimo zvakanyanyisa, ma mechanics ayo anodzikira zvakanyanya.Muzviitiko zvakawanda, pane kukosha kwakakosha kune zviri mukati meiyo nylon 6 matrix, uye pasi pehukoshi uhwu, mafirita anopindirana, kuitira kuti agadzire mesh kana cheni-yakafanana nekushisa conduction network cheni. nylon 6 matrix uye nekudaro wedzera thermal conductivity.

4. Kuvandudza chimiro chekubatanidza hunhu pakati pekuzadza nenylon 6 matrixIyo yakakwira dhigirii remubatanidzwa pakati pekuzadza uye naironi 6 matrix, zviri nani kudziya kwekupisa.Iko kurapwa kwepamusoro pazadza neakakodzera yakafanana maleic anhydride graft compatilizer uye coupling agent inogona kuvandudza hunhu pakati penylon 6 uye filler, uye iyo yekupisa conductivity coefficient ye thermal conductive nylon 6 zvinhu zvinogona kuwedzerwa ne10% kusvika makumi maviri. %.
