Funso mwachangu lokhudza cellulose et

01. Ntchito yayikulu ya cellulose ether hpmc?

HPMC imagwiritsidwa ntchito ndi matope omanga, utoto wopangidwa ndi madzi, zopangidwa ndi zitsulo, zosakaniza, chakudya, chakudya, chodzola, fodya, ndi mafakitale ena. Imagawidwa m'gulu la kalasi yomanga, kalasi ya chakudya, kalasi ya mankhwala a mankhwala, pvc mafakitale ndi kalasi ya tsiku ndi tsiku.

02. Kodi ma cellulose ndi ati?

Maselo wamba ndi MC, HPMC, Mic, CMC, Hec, EC
Pakati pawo, Hec ndi CMC amagwiritsidwa ntchito kwambiri pakuyamika madzi,
CMC itha kugwiritsidwanso ntchito mu ceramics, munda wamafuta, chakudya ndi minda ina
EC imagwiritsidwa ntchito kwambiri mu mankhwala, siliva wamakono ndi malo ena
HPMC imagawidwa m'mataito osiyanasiyana matope, mankhwala, chakudya, malonda a PVC, mankhwala amankhwala a mankhwala ndi mafakitale ena

03. Kodi pali kusiyana kotani pakati pa HPMC ndi Miche mu pulogalamu?

Mayipi a mitundu iwiri ya cellulose ndi chimodzimodzi, koma kutentha kwambiri kwa nthawi yachilimwe, makamaka kutentha kwa khoma pomwe kutentha kwa mahec kuli bwino kuposa kutentha kwa hpmc.

04. Momwe angangoweruza mtundu wa HPMC?

1) Ngakhale kuyera sikungadziwe ngati HPMC ndikosavuta kugwiritsa ntchito, ndipo ngati odekha amawonjezeredwa pakupanga, ndiye kuti zinthu zabwino zimakhala ndi kuyera kwabwino, komwe kumatha kuweruzidwa bwino.
2) Kupendekera Kuwala: Atatha kusungunula hpmc m'madzi kuti apange cololoid colloid, yang'anani pakuwunikira kwake. Zabwino zonse zowunikira, chinthu chocheperako chomwe chilipo, ndipo khalidweli ndilabwino.
Ngati mukufuna kuweruza molondola pa cellulose, njira yodalirika ndiyogwiritsa ntchito zida zaukadaulo mu labotale ya akatswiri yoyesedwa. Zizindikiro zazikulu zoyeserera zimaphatikizapo mafakisoni, kusunga madzi, ndi phulusa.

05. Momwe mungayesere mafayilo a cellulose?

Wofikitsa wofala mu msika wa cellulose ndi NDJ, koma pamsika wapadziko lonse lapansi, opanga osiyanasiyana nthawi zambiri amagwiritsa ntchito njira zoyeserera za Visction. Anthu wamba ndi Broookfeld RV, Hupler, ndipo palinso mayankho osiyanasiyana, omwe amagawidwa mu 1% yankho ndi 2% yankho. Zosachedwa masholo osiyanasiyana komanso njira zosiyanasiyana zomwe zimapangitsa kuti nthawi zingapo zitheke kapena nthawi zambiri m'mavuto.

06. Kodi pali kusiyana kotani pakati pa mtundu wa hpmc pompopompo ndi mtundu wosungunuka?

Zogulitsa za HPMC zimatchulapo zinthu zomwe zimabalalika msanga m'madzi ozizira, koma ziyenera kudziwika kuti kubala sizitanthauza kuti sizingachitike. Zogulitsa nthawi yomweyo zimathandizidwa ndi glyloxal pamtunda ndikumwazika m'madzi ozizira, koma siziyamba kusungunuka nthawi yomweyo. , kotero ma viscy samapangidwa pomwepo mutabalalika. Kuchuluka kwa chithandizo cha glymoxal pamtunda, kumawonjezera mwachangu, koma pang'onopang'ono ma visctoni, ocheperako kuchuluka kwa Glyloxal, komanso mosemphanitsa.

1.
Tsopano pali cellulose yambiri yosinthidwa ndi celluose yopaka pamsika, ndiye kuti kusinthaku ndi kotani?

Cellulose yamtunduwu nthawi zambiri imakhala ndi katundu yemwe amakhala ndi katundu woyambirirawu kapena wowonjezerapo kuti makampani ambiri amakonzeranso ma celluuse kapena osinthika
