Uburyo busanzwe kandi bworoshye bwo gutandukanya ubuziranenge bwa selile HPMC ：
1. Imiterere igaragara ya selile ya HPMC yuzuye ni fluffy, kandi ubwinshi bwinshi ni buto, hamwe na 0.3-0.4g / ml; HPMC yasambanijwe ifite selile nziza kandi ifite amaboko aremereye, ibyo bikaba bitandukanye cyane no kugaragara kwibicuruzwa byukuri.
2. Umweru wa selile HPMC yera ni nziza, bivuze ko ibikoresho fatizo bikoreshwa mu musaruro ari byiza kandi reaction ikaba yuzuye neza nta mwanda. Ugereranije nibicuruzwa bya selile byo mu mahanga bifitanye isano, birashobora kugaragara ko umweru wibicuruzwa byiza bya selile nziza ya ether buri gihe ari byiza kuruta ibicuruzwa byo murugo rwa kabiri.
3. Amazi meza ya HPMC selile yamazi arasobanutse, hamwe no kohereza urumuri rwinshi, nigipimo cyo gufata amazi ≥ 97%; Umusemburo w'amazi ya HPMC wasambanijwe ni umuyonga, kandi igipimo cyo gufata amazi kiragoye kuzuza ibisabwa. Ihererekanyabubasha ryumuti wamazi nibyiza, byerekana ko ibicuruzwa birimo ibintu bitangirika kandi nibintu byinshi byingirakamaro.
4. Cellulose nziza ya HPMC ntigomba kunuka ammonia, ibinyamisogwe n'inzoga; Selulose yanduye HPMC irashobora guhumura ubwoko bwose bwibiryo. Nubwo yaba idafite uburyohe, izumva iremereye.
5. Ifu ya HPMC isukuye ni fibrous munsi ya microscope cyangwa ikirahure kinini; Cellulose ya HPMC yasambanijwe irashobora kugaragara nka granular ikomeye cyangwa kirisiti munsi ya microscope cyangwa ikirahure kinini.
6. Uburyo bworoshye bwo kwipimisha kubintu byivu bya selulose ether: gupima garama imwe kugeza kuri ebyiri za selile ya selile, kuyitwika ukoresheje urumuri, gupima igisigara cy ivu cyasizwe no gutwikwa na selile, kandi mugihe ibisigazwa by ivu / selile ya selile ari ≥ 5 %, ubwiza bwa selile ether ntabwo yujuje ibyangombwa. .
7. Inganda zimwe ningo zikoresha selile nkeya ya C ivanze na hydroxypropyl methyl selulose ether, kandi mugihe igisubizo cyamazi ya C selile gihuye na tin, silver, aluminium, gurş, fer, umuringa hamwe nibyuma bimwe biremereye, hazabaho reaction yimvura; Iyo c-selile yumuti wamazi ubanye na calcium, magnesium numunyu, ntabwo bizatanga imvura, ahubwo bizagabanya ubukonje bwumuti wamazi wa c-selile.
8. Niba ibintu bibyemereye, gerageza neza ubwiza bwumuti wamazi wa selile ether hanyuma ugereranye igipimo cyo gufata amazi yibintu bike bya selile ether mortar
Nkumushinga wabigize umwuga wa selile, Y.oungcel selulose Azatanga n'umutima we wose ibicuruzwa na serivisi nziza
