Qhov hnyav molecular ntawm HPMC tuaj yeem qhia tau los ntawm nws cov tshuaj viscosity hauv cov kuab tshuaj siv.
Tshwj tsis yog hais tias muaj lwm yam, qhov hnyav molecular ntawm HPMC ntsuas ntawm no nrog UBBELOHDE viscometer ntawm 20 ℃ siv cov tshuaj aqueous uas muaj 2% (qhov hnyav) ntawm HPMC.
Nws cov degree withering feem ntau yog li 5 txog 200000 mpa. Sd siv hydroxypropyl methyl cellulose ether ua tus neeg sawv cev rau ncua kev kawm ntawv polymerization ntawm ethylene unsaturated monomers. Qhov kev xaiv ruaj khov yog li 5 mpa. s, los ntawm lOmpa. S. mus txog 400 mpa. s, uas yog hais txog I00mPa. s.
S, 10100, thiab 400mpa S yog feem sib npaug rau tus lej nruab nrab molecular hnyav ntawm 1000013000,26000, thiab 410000 HPMC ether aqueous kua siv los ua thickener raws li kev tsim thiab viscosity ntawm 20 ℃, tsawg kawg yog li ntawm l. Nws yog qhov zoo dua yog hais txog 15000 mpa. s, yog li qhov viscosity ntawm cov tshuaj feem ntau yog txog li 200000 rau iso, thiab nws zoo dua yog 120000 rau 100000 m pa. s, thiab nws zoo dua yog 75000 mpa Yog li tus lej nruab nrab molecular hnyav (M).
Qhov nruab nrab molecular hnyav (M) ntawm tus lej a tuaj yeem txiav txim siab los ntawm osmometry los ntawm kwv yees li 20000, zoo dua los ntawm 55000, zoo dua los ntawm 120000; Txog 280000, 250000 zoo dua, thiab 2200000 zoo dua.
Youngcel HPMC/MHEC Nws yog dav siv los ua Tus Neeg Sawv Cev Pabcuam rau Pobzeb Adhesive, Cement Plaster, Qhuav mix mortar, Phab ntsa putty, Txheej, Detergent thiab lwm yam.Thiab peb tuaj yeem muab koj tus nqi qis tshaj thiab zoo tshaj plaws.
Peb cov khoom yog nrov nyob rau hauv Egypt, Russia, South Africa, Middle East, qaib ntxhw, Nyab Laj, Fabkis, Ltalis, Singapore, Bangladesh, Indonesia, South America thiab hais txog. Ua tsaug ua ntej thiab txais tos hu rau.
