Yuav ua li cas txheeb xyuas thiab xaiv ntawm PA6 hloov kho thiab PA66 (Pib 1) li cas?

Nrog kev loj hlob zuj zus ntawm kev hloov kho nylon R & D thev naus laus zis, daim ntawv thov ntawm PA6 thiab PA66 tau maj mam nthuav dav. Ntau cov khoom lag luam yas lossis cov neeg siv cov khoom siv nylon yas tsis paub meej txog qhov sib txawv ntawm PA6 thiab PA66. Tsis tas li ntawd, vim tias tsis muaj qhov pom tseeb pom qhov txawv ntawm PA6 thiab PA66, qhov no tau ua rau muaj kev ntxhov siab ntau. PA6 thiab PA66 txawv li cas, thiab lawv yuav tsum xaiv li cas?

Ua ntej, Cov Lus Qhia rau Kev Txheeb Xyuas PA6 thiab PA66:
Thaum kub hnyiab, ob qho tib si PA6 thiab PA66 emit ib tug ntxhiab tsw zoo li burnt ntaub plaub los yog rau tes. PA6 ua rau cov nplaim daj, thaum PA66 hlawv nrog cov nplaim xiav. PA6 muaj qhov toughness zoo dua, yog pheej yig dua PA66, thiab muaj qhov qis qis (225 ° C). PA66 muaj lub zog ntau dua, hnav tsis kam, thiab cov ntsiab lus melting ntau dua (255 ° C).

Thib ob, Qhov sib txawv ntawm lub cev muaj zog:

• PAB 66:Melting point: 260-265 ° C; iav hloov kub (lub xeev qhuav): 50 ° C; Qhov ceev: 1.13-1.16 g / cm³
• PA 6:Semi-pob tshab los yog opaque milky-dawb crystalline polymer pellets; melting point: 220 ° C; decomposition kub: siab tshaj 310 ° C; txheeb ze ntom ntom: 1.14; Kev nqus dej (24 teev hauv dej ntawm 23 ° C): 1.8%. Nws muaj kev hnav zoo heev thiab nws tus kheej lubrication, siab txhua yam muaj zog, zoo tshav kub tsis kam thiab hluav taws xob rwb thaiv tsev zog, kev ua tau zoo ntawm qhov kub thiab txias, nws tus kheej-extinguishing zog, thiab tshuaj tiv thaiv-tshwj xeeb tshaj yog roj kuj.

Piv rau PA66, PA6 yooj yim dua rau txheej txheem thiab pwm, muaj qhov zoo dua qhov ci hauv cov khoom tiav, thiab muaj qhov dav dav siv tau ntau yam. Txawm li cas los xij, nws muaj qhov nqus dej ntau dua thiab qhov tsis zoo ntawm qhov ntev. Nws tsis tshua muaj zog, muaj qhov qis melting point, thiab tuaj yeem siv tau ntev hauv qhov chaw hnyav. Nws tuav cov kev ntxhov siab zoo thoob plaws qhov kub thiab txias, nrog rau qhov kub thiab txias ntawm 105 ° C.

Thib peb, Yuav Ua Li Cas Txiav Txim Siab Siv PA66 lossis PA6?
Kev sib piv ntawm PA6 thiab PA66:

• Mechanical zog: PA66> PA6
• Kev ua haujlwm kub: PA66> PA6
• Nqe: PA66> PA6
• Melting point: PA66> PA6
• Kev nqus dej: PA6> PA66

Plaub, Qhov txawv ntawm Daim Ntawv Thov Scope:

• PA6 engineering yasmuaj lub zog tensile siab, muaj kev cuam tshuam zoo, hnav tsis kam, tshuaj lom neeg, thiab kev sib txhuam coefficient tsawg. Los ntawm kev hloov kho xws li iav fiber reinforcement, ntxhia filling, los yog nplaim retardant additives, lawv cov kev ua tau zoo tag nrho tuaj yeem txhim kho ntxiv. Lawv tsuas yog siv rau hauv kev lag luam tsheb thiab hluav taws xob / hluav taws xob.
• PAB 66muaj kev ua tau zoo tag nrho, suav nrog lub zog siab, rigidity, cuam tshuam tsis kam, roj thiab tshuaj ua haujlwm, hnav tsis kam, thiab nws tus kheej lubrication. Nws tshwj xeeb tshaj yog nyob rau hauv hardness, rigidity, tshav kub tsis kam, thiab creep kuj. Vim nws lub zog ntau dua piv rau PA6, PA66 feem ntau siv rau hauv kev lag luam xws li cov log tsheb cord ntau lawm.
