Yuav Ua Li Cas Txhim Kho Thermal Conductivity ntawm Nylon 6 Khoom?

Cov yam ntxwv cuam tshuam rau cov thermal conductivity ntawm nylon 6 cov khoom nyob rau hauv cov ntaub ntawv ntawm cov khoom ruaj khov thiab sib txuam

Plaub yam:

• Thermal conductivity coefficient ntawm slices thiab fillers ntawm nylon 6 puag Tshuag;

• Dispersity thiab bonding degree ntawm fillers nyob rau hauv nylon 6 matrix;

• Cov duab thiab cov ntsiab lus ntawm fillers;

• Qhov sib txuas sib txuas cov yam ntxwv ntawm cov fillers thiab nylon 6.

Kev txhim kho ntawm thermal conductivity ntawm thermal conductive nylon 6 khoom tuaj yeem pib los ntawm plaub yam

1. Kev siv cov hlais thiab cov khoom ntim ntawm nylon 6 lub hauv paus Tshuag nrog cov thermal conductivity coefficient ntau dua.Lub thermal conductivity ntawm ntshiab nylon 6 daim yog feem ntau los ntawm 0.244 mus rau 0.337W / MK, thiab nws cov nqi yog ze ze rau cov txheeb ze viscosity ntawm polymer, kev faib ntawm molecular hnyav thiab orientation ntawm lub polar molecule.

Fillers siv rau kev hloov kho ntawm non-insulator thermal conductive nylon 6 suav nrog txhuas, tooj liab, magnesium thiab lwm yam hlau hmoov nrog rau graphite thiab carbon fiber, thiab lwm yam. Qhov siab dua thermal conductivity coefficient ntawm cov hmoov hlau yog, qhov zoo dua thermal conductivity. yog.Txawm li cas los xij, xav txog qhov zoo, tus nqi thiab kev ua haujlwm ntawm cov ntaub ntawv sib txawv, cov hmoov txhuas yog qhov zoo dua qub.Fillers siv rau kev hloov kho ntawm insulator thermal conductive nylon 6 suav nrog alumina thiab magnesium oxide.Alumina yog pheej yig, zoo, thiab yooj yim rau txheej txheem, uas tau txais los ntawm ntau tus neeg muas zaub.

2. Txhim kho qhov zoo ntawm cov muab tub limRau cov muab tub lim siv nyob rau hauv cov khoom siv thermal conductive nylon 6, cov thermal conductivity ntawm cov muab tub lim yog qhov zoo dua yog tias nws muaj txiaj ntsig zoo rau kev tsim cov thermal conduction.Qhov kev txiav txim txheeb ze yog Whisker> Fibrous> Flake> Granular.Qhov me me me me ntawm cov muab tub lim, qhov zoo dua qhov dispersity hauv nylon 6 matrix, qhov zoo dua thermal conductivity.

3. Kev siv cov fillers nrog cov ntsiab lus nyob ze ntawm tus nqi tseem ceebYog hais tias cov ntsiab lus ntawm thermally conductive plastics fillers nyob rau hauv nylon 6 yog me me heev, cov thermal conductivity nyhuv tsis pom tseeb, thiab qhov loj feem ntau tshaj 40% nyob rau hauv ntau zaus.Txawm li cas los xij, yog tias cov ntsiab lus siab dhau lawm, nws cov khoom siv kho tshuab yuav txo qis heev.Feem ntau, nws yog ib qho tseem ceeb rau cov ntsiab lus ntawm cov muab tub lim nyob rau hauv nylon 6 matrix, thiab nyob rau hauv tus nqi no, cov muab tub lim yuav cuam tshuam nrog ib leeg, thiaj li tsim ib tug mesh los yog saw-zoo li kub conduction network saw nyob rau hauv lub nylon 6 matrix thiab yog li ua kom cov thermal conductivity.

4. Txhim kho qhov sib txuas sib txuas cov yam ntxwv ntawm cov muab tub lim thiab nylon 6 matrixQhov siab dua ntawm kev sib xyaw ua ke ntawm cov muab tub lim thiab nylon 6 matrix, qhov zoo dua thermal conductivity.Kev kho saum npoo ntawm cov muab tub lim nrog qhov tsim nyog zoo ib yam li txiv neej anhydride graft compatilizer thiab coupling tus neeg sawv cev tuaj yeem txhim kho cov yam ntxwv ntawm cov nylon 6 thiab cov muab tub lim, thiab thermal conductivity coefficient ntawm thermal conductive nylon 6 cov khoom tuaj yeem nce 10% mus rau 20. %.
