Zus tau tej cov Cardboard los Husk mov khib

Jun 28, 2016

Paub daws teeb

Husk mov tsis muaj ntau yam pauv loj tej nqi thiab feem ntau tuaj ua tej teeb meem txog nws pov tseg. Qhov kev tshawb nrhiav pom tus ntsuam uas yuav ua tau duab los qhia los ntawm cov nplej husk, li no, kom txhob muaj muaj nyiaj pulping cov khoom yuav tsum los ntawm nkauj xwb tus ntoo. Maceration txoj kev siv los mus tsim cardboards ntawm cov pulps. Kev ntsuas comparative, nrog rau cov txhuv husk, bagasse thiab ntawv pov tseg tau siv. Lub tom kawg tau zoo nyob rau ntau lub cim thiab nws ua tau txhua yam tau pom hais tias. Husk nplej muaj nyob lignin 15.2%, 20.56% cov ntoo tshauv muaj kappa ntau 99.48 thaum bagasse muaj 13.70% lignin thiab 2.23% cov ntoo tshauv muaj kappa ntau 88.39. Lub sij hawm maceration mov husk thiab bagasse yog 6 thiab 15 hnub thiab 5-10 hnub nrog tus coj sis plawv hniav yield 40.44 – 46.55% thiab 46.01 – 36.76%, feem. Cov ntsiab lus lignin nruab nrab ntawm cov nplej husk sis plawv hniav thiab bagasse sis plawv hniav heev 3.09 – 2.9% 2.95 – 2.43%, feem. Tensile Performance index, edgewise tuav hauj, thaj tsam li bursting Performance index cov duab los qhia los ntawm cov nplej husk heev 11.31 N m/j, 1.11 kN/m 0.84 kPa m2/g, feem. Rau cov txhuv husk xyaw bagasse duab los qhia, cov cim kev pom tau (20/80), (40/60), thiab (60/40) nrog ib tug tensile Performance index ntawm 17.96, 16.66 thiab 12.94 N m/j, feem. Cov edgewise compressive kuj yog 2.91, 2.42 thiab 1.99 kN/m, feem. Lub bursting Performance index yog 1.88, 1.55 thiab 1.26 kPa m2/g, feem. Cov mov noj husk mov mixed ntawv piv tau (20/80) nrog ib tug tensile Performance index ntawm 21.52 N m/g uas tau ua hauj edgewise compressive ntawm 2.75 kN/m thiab ib bursting Performance index ntawm 1.35 kPa m2/g. Li no, cov cardboards yog tsim rau ntim li corrugating txiag nruab nrab, wrapping thiab insulating.
