Hydroxypropyl methylcellulose, izwi kandi nka hypromellose na selulose hydroxypropyl methyl ether, ikozwe muri selilose nziza yipamba kandi ikaba idasanzwe cyane mugihe cya alkaline.
itandukaniro:
ibiranga bitandukanye
Hydroxypropyl methylcellulose: ifu yera cyangwa yera isa na poro cyangwa granules, yubwoko butandukanye butari ionic buvanze na selile, iki gicuruzwa nigice cya sintetike, idakora ya viscoelastic polymer.
Hydroxyethyl selulose ni umweru cyangwa umuhondo, impumuro nziza, fibre idafite uburozi cyangwa ifu ikomeye, ibikoresho nyamukuru ni alkali selulose na etylene oxyde etherification, ikaba ari ether ya ionic soluble selile.
Gukoresha biratandukanye
Mu nganda zisiga amarangi, hydroxypropyl methylcellulose ifite imbaraga zo gukemura neza mumazi cyangwa ibishishwa kama nkibibyimbye, bikwirakwiza kandi bigahindura. Polyvinyl chloride ikoreshwa nk'ikuraho irangi kugirango ihagarike polymerisation kugirango itegure polyvinyl chloride, ikoreshwa cyane mu mpu, mu mpapuro, kubungabunga imbuto n'imboga, imyenda n'inganda.
Hydroxypropyl methylcellulose: hafi idashonga muri Ethanol yuzuye, ether, acetone; gushonga mu mucyo cyangwa mu gihirahiro cya colloidal mumazi akonje, akoreshwa cyane mugutwikira, wino, fibre, gusiga irangi, gukora impapuro, kwisiga, imiti yica udukoko, amabuye y'agaciro Gutunganya ibicuruzwa, kugarura amavuta ninganda zimiti.
gutandukana
Hydroxypropyl methylcellulose: hafi idashonga muri Ethanol yuzuye, ether, acetone; gushonga mumazi meza cyangwa yibicu bya colloidal mumazi akonje.
Hydroxyethyl selulose (HEC): Irashobora gutegura ibisubizo muburyo butandukanye bwijimye, kandi ifite ibyiza byo gushonga umunyu kuri electrolytike.
