Yuav ua li cas thiaj paub thiab xaiv tau ntawm PA6 thiab PA66 uas tau hloov kho (Ntu 1)?

Yuav ua li cas thiaj paub thiab xaiv tau ntawm PA6 thiab PA66 uas tau hloov kho (Ntu 1)?

Nrog rau kev loj hlob ntawm cov thev naus laus zis nylon hloov kho R&D, qhov kev siv ntawm PA6 thiab PA66 tau nthuav dav maj mam. Ntau tus neeg tsim khoom yas lossis cov neeg siv cov khoom yas nylon tsis meej txog qhov sib txawv ntawm PA6 thiab PA66. Tsis tas li ntawd, txij li tsis muaj qhov sib txawv pom tseeb ntawm PA6 thiab PA66, qhov no tau ua rau muaj kev tsis meej pem ntau. Yuav ua li cas thiaj paub qhov txawv ntawm PA6 thiab PA66, thiab yuav tsum xaiv lawv li cas?

Ua ntej, Cov Lus Qhia rau Kev Txheeb Xyuas PA6 thiab PA66:
Thaum hlawv, ob qho tib si PA6 thiab PA66 tso tawm ib qho tsw zoo li cov plaub hau hlawv lossis cov rau tes. PA6 tsim cov nplaim daj, thaum PA66 hlawv nrog cov nplaim xiav. PA6 muaj zog dua, pheej yig dua PA66, thiab muaj qhov melting qis dua (225 ° C). PA66 muaj zog dua, tiv taus kev hnav zoo dua, thiab qhov melting siab dua (255 ° C).

Qhov thib ob, Qhov sib txawv ntawm Cov Khoom Siv Lub Cev:

• PA66:Qhov kub yaj: 260–265°C; qhov kub hloov iav (qhuav): 50°C; qhov ceev: 1.13–1.16 g/cm³.
• PA6:Cov pellets polymer crystalline semi-transparent los yog opaque milky-white; melting point: 220°C; decomposition temperature: siab tshaj 310°C; relative density: 1.14; dej nqus (24 teev hauv dej ntawm 23°C): 1.8%. Nws muaj kev tiv thaiv kev hnav zoo heev thiab kev ua kom nws tus kheej lubrication, lub zog siab mechanical, zoo tiv thaiv kub thiab hluav taws xob rwb thaiv tsev, zoo ua haujlwm kub qis, nws tus kheej tua hluav taws, thiab tshuaj lom neeg - tshwj xeeb tshaj yog tsis kam roj.

Piv rau PA66, PA6 yooj yim dua rau kev ua thiab pwm, muab qhov ci ntsa iab zoo dua hauv cov khoom tiav, thiab muaj qhov kub thiab txias siv tau dav dua. Txawm li cas los xij, nws muaj kev nqus dej ntau dua thiab kev ruaj khov tsis zoo. Nws tsis khov kho, muaj qhov kub yaj qis dua, thiab siv tau ntev hauv qhov chaw nyuaj. Nws tswj tau qhov kev ntxhov siab zoo thoob plaws ntau qhov kub thiab txias, nrog rau qhov kub thiab txias tas mus li ntawm 105 ° C.

Qhov thib peb, Yuav Ua Li Cas Txiav Txim Siab Seb Puas Siv PA66 lossis PA6?
Kev sib piv ntawm kev ua tau zoo ntawm PA6 thiab PA66:

• Cov khoom siv kho tshuab: PA66 > PA6
• Kev ua haujlwm thermal: PA66 > PA6
• Nqe: PA66 > PA6
• Melting point: PA66 > PA6
• Kev nqus dej: PA6 > PA66

Plaub, Qhov Sib Txawv Hauv Daim Ntawv Thov Scope:

• PA6 engineering yasmuaj lub zog tensile siab, tiv taus kev cuam tshuam zoo, tiv taus kev hnav zoo heev, tiv taus tshuaj lom neeg, thiab coefficient sib txhuam tsawg. Los ntawm kev hloov kho xws li iav fiber reinforcement, mineral filling, lossis flame retardant additives, lawv cov kev ua tau zoo tag nrho tuaj yeem txhim kho ntxiv. Lawv feem ntau yog siv hauv kev lag luam tsheb thiab electronics / hluav taws xob teb.
• PA66muaj kev ua tau zoo tshaj plaws, suav nrog lub zog siab, kev ruaj khov, kev cuam tshuam, roj thiab tshuaj lom neeg tsis kam, kev hnav tsis kam, thiab kev ua kom lubrication tus kheej. Nws tshwj xeeb tshaj yog ua tau zoo hauv qhov nyuaj, kev ruaj khov, kev kub tsis kam, thiab kev nkag tsis kam. Vim nws muaj zog dua piv rau PA6, PA66 feem ntau siv rau hauv kev siv hauv kev lag luam xws li kev tsim cov log tsheb.
