Analysis ntawm organic binders
Nyob rau hauv peb cov phaj kev sib txhuam, tsis muaj teeb meem li cascov khoom sib txhuamhloov, muaj ib txwm ib yam khoom, uas yog organic binder, thiab nws yog ib tug ntawm cov tseem ceeb Cheebtsam nyob rau hauv cov khoom sib txhuam. Niaj hnub no peb yuav tham txog no organic binder.
Feem ntau muaj ob hom organic binders: cob thiab roj hmab. Nws txoj haujlwm yog ua kom zoo sib xws ntawm txhua hom fibers, fillers thiab auxiliary cov ntaub ntawv nyob rau hauv cov ntaub ntawv sib txhuam nyob rau hauv daim ntawv ntawm ib tug bonding zaj duab xis, ua ib tug compact qauv nrog lub zog loj thiab Friction daim hlau uas muaj peev xwm ua tau raws li qhov yuav tsum tau ua ntawm kev sib txhuam cov ntaub ntawv.
Organic bonding yog qhov tseem ceeb ntawm cov khoom siv sib txhuam Le, thiab qhov ntau npaum li cas rau 8 feem pua -25 feem pua ntawm cov khoom. Cov resin yog cov khoom tseem ceeb ntawm cov organic binder, thiab cov roj hmab yog cov khoom siv, tab sis rau cov khoom siv sib txhuam thiab cov khoom sib txhuam, cov roj hmab yuav ntau dua cov ntsiab lus ntawm cov resin.
Rau cov organic binder nyob rau hauv kev sib txhuam phaj, nws cov tshav kub kuj tseem ceeb heev. Thaum cov khoom siv khiav, qhov kub ntawm qhov sib txhuam phaj tuaj yeem siab li 200-400degree. Lub sijhawm no, lwm cov ntaub ntawv sib txhuam yuav tsis ncav cuag qhov kub ntawm thermal decomposition. Txawm li cas los xij, cov resin thiab roj hmab tau mus txog qhov kub thiab txias ntawm thermal decomposition, thiab ntau yam kev ntsuas ntawm kev sib txhuam phaj yuav muaj kev hloov pauv tsis zoo nyob rau lub sijhawm no. Yog li ntawd, kev xaiv thiab qhov sib piv ntawm cov khoom sib txhuam yuav tsum tau tswj kom zoo.
