1 Kodi ndi ntchito zazikulu ziti za 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.
2 Kodi ma cellose 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, minda yamafuta, chakudya ndi minda ina;
EC imagwiritsidwa ntchito kwambiri mu mankhwala, phazi siliva wamagetsi ndi minda ina;
HPMC imagawidwa m'malingaliro osiyanasiyana ndipo imagwiritsidwa ntchito mu matope, mankhwala, chakudya, malonda a PVC, mankhwala amankhwala amasiku tsiku lililonse.
Kodi pali kusiyana kotani pakati pa HPMC ndi Ahec pakugwiritsa ntchito?
Zophatikiza mitundu iwiri ya cellulose ndizofanana, koma kutentha kwambiri kumalibwino, makamaka nthawi yachilimwe pomwe kutentha kwa khoma kumakhala kwabwino kwambiri .
4 Momwe mungangongoweruza 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.
5 Njira Ya Viscence Codinetion of 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.
Kodi pali kusiyana kotani pakati pa mtundu wa HPMC Kumpopompo ndi Mtundu Wotentha?
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.
7 celluose yophatikizika ndi celluose yosinthidwa
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 zina, otsutsa, omwe amakulitsa nthawi yopanga, ndi zina zambiri, ziyenera kudziwidwa kuti makampani ambiri Gwiritsani ntchito cellulose yotsika mtengo yomwe imayesedwa kuti muchepetse ndalama zimatchedwa celluuse yapamwamba kapena cellulose yosinthidwa. Monga ogula, yesani kusiyanitsa ndi kusapusitsidwa. Ndikofunika kusankha zinthu zodalirika kuchokera ku mitundu yayikulu ndi mafakitale akuluakulu.
