Polyamide Nylon PA66 Txoj Hlub Ntsej Nyiam rau Cov Chaw Tso Tsij Tsis Txog

Lub npe muaj peev xwm "polyamide nylon" tsim nyog ua ke ua ib qhov kev tshuaj txwv kev kawm, txhawj tias cov khoom siv yog ib qho khoom polyamide nyuj. Nws feem ntau siv hauv cov lej ntsiag kev kawm, cov ntsiab lus xa khoom, thiab kev pab xov xwm kho tshuaj kom tshem tawm yam tsis meej ntsis, kom ntseeg tias cov ntsiab lus hais rau cov polyamides aliphatic feem ntau xws li PA6, PA66, PA610 lossis cov duav ntxiv, tsis yog lwm qhov members ntawm polyamide tseem ceeb. Qhov no yog qhov tseem ceeb vim tias lub npe tsha yas "polyamide" tsuas yog, nyob ze, tuaj yeem muaj cov neeg siv ntau thiab ntau taim npaum li PPA aromatic lossis polyamides tsha, uas muaj siv sib txawv heev, kev them nqi, thiab nqi. Los ntawm kev siv "polyamide nylon," lub nqes siab raug suav nrog rau cov khoom siv tseem ceeb uas coob tshaj plaws hauv zaj piv. Cov khoom no tau pom zoo rau lawv lub zog zoo, txaus siab, thiab kev tiv thaiv. Ib qhov kev txiav txim siab tseem ceeb uas txwv rau qhov no yog lawv qhov kev nyob ruaj ruaj. Lawv yuav tsum siv tag nrho ua ntej (feem ntau saum 0.2% tus nqi dej) kom tiv thaiv kev puav tswj thiab kev los ntawm kev siv tshuaj. Txij li cas los, lawv kev crystallinity cuam tshuam mus rau kev rov qab loj dua nyob rau sab nraud cooling, ib qhov tseem ceeb tshaj plaws uas yuav tsum muaj kev xav kom meej meej rau hauv kev kho tshuaj thiab kev kho tshuaj. Kawm qhov no txhais le lus kom paub meej across the supply chain, los ntawm cov khoom siv khoom siv thiab cov neeg kho tshuaj mus rau cov neeg siv tshuaj, kom ntseeg tias cov khoom siv tshuaj, raws li cov ntaub ntawv historical feem ntau rau nyuj, yog ib txwm tau.
