HydroxyPropyl Methylcellse HPMC ikoreshwa muri rusange mu musaruro w'imbere kandi hanze ya selile ya 200.000, kandi mu bindi miseri ya charpos, kandi mu bindi miri ya selile, bikunze gukoreshwa virusi ya 400. Ubugari bwa selile, iki gicuruzwa gifite ingaruka nziza z'amazi, ingaruka nziza zijimye kandi zifite ireme. HPMC ikoreshwa cyane mubikoresho byo kubaka kandi ikoreshwa mumafaranga menshi. Ubutugo burashobora gukoreshwa nkumucuruzi, umukozi ushinzwe kugumana amazi, umubyimba na binder. Uburenganzira bwa Cellulose bugira uruhare runini muri minisiteri isanzwe yumye, abigana urukuta rwo hanze, kwishyira hamwe kwa pertar, bihurira kandi bihuje kandi bihuje na minisiteri.
Bikunze gukoreshwa na selile birimo hec, HPMC, CMC, PMC, MHEC, Mhec, Gutandukana Amazi ya Dother, Gutandukana Amazi ya Dother hamwe na Gutandukanya amazi, kandi ni ngombwa kongera gutanga ibikoresho byo kubaka. HPMC, MC cyangwa Ehec ikoreshwa mu nyubako nyinshi zishingiye ku nyongeragaciro cyangwa gysum, nka centring minisiteri, gypsum, zirashobora kunoza amata ya sima, n'ibindi, bikaba ari ngombwa cyane kuri plant, bikabije. HEC ikoreshwa muri sima, ntabwo ari umucuruzi gusa, ariko kandi nkumukozi ugumana amazi, kandi heHPC nayo ikoreshwa muriki kibazo. MC cyangwa hec bakunze gukoreshwa hamwe na CMC nkigice gikomeye cya Wallpaper. Hagati-viscosiya cyangwa violitura-selile bakunze gukoreshwa muri wallpaper ibikoresho byubaka.
Imitungo ya hydroxypropyl methylcellse
HydroxyPropyl Methylcellse Ibicuruzwa Hpmc guhuza imitungo myinshi yumubiri na shimi kugirango ibe ibicuruzwa byihariye hamwe nibikoresho byinshi. Ibintu bitandukanye ni ibi bikurikira:

(12) uburyohe kandi butagira impumuro, ntibiterwa na metabolism; ikoreshwa nk'ibiryo n'ibiyobyabwenge, ntibazateganyirizwa mu biryo kandi ntibazatanga karori.
Inzira rusange kandi yoroshye kugirango umenye ubuziranenge
1. HPMC yera iragaragara kandi ifite ubucucike bugufi buke, kuva kuri 0.3-0.4g / ml; Yasambanye HPMC ifite amazi meza kandi yumva aremereye, biragaragara ko bitandukanye nibicuruzwa byukuri mumiterere.
2. HPMC yera ifite igihano cyiza, bivuze ko ibikoresho fatizo bikoreshwa mubikorwa byera, kandi reaction irarubashye ntamwanda utagira umwanda. Ugereranije nibijyanye na selile ya selile ya ether, birashobora kugaragara ko cyera cyibicuruzwa byiza bya cother bihora biruta ibyo bicuruzwa byimiryango ya kabiri.
3.. Igisubizo cyera cya HPMC gisobanutse neza, umukono woherejwe, igipimo cyo kugumana amazi ≥ 97%; Yasambanye hpmc igisubizo cyibitangaza ni turbid, kandi igipimo cyo kugumana amazi biragoye kubahiriza ibisabwa. Umucyo ushyirwaho igisubizo cyibitangaza ni byiza, byerekana ko ibicuruzwa birimo ibintu bidashomeze kandi bifite ibintu byinshi mubigize.
4. HPMC yera idakwiye kunuka Ammonia, udusimba n'inzoga; HPMC yasambanijweho nakunze kunuka impumuro zose, nubwo yaba afite impumuro, izumva iremereye.
5. Ifu ya HPMC yera ni fibrous munsi ya microscope cyangwa ikirahure kinini; Yasambanijwe HPMC irashobora kubahirizwa nkibisubizo bya granular cyangwa kristu munsi ya microscope cyangwa ikirahure.
6. Uburyo bworoshye bwo kwipimisha ku mvura ya selile ni ugupima garama imwe kugeza kuri bibiri bya selile, bikaboroga bikabije, kandi bipima umucyo, kandi gapima isi yavuye inyuma nyuma yuburenganzira bwa selile bwagatwitse. Iyo ash residue / selile ether ≥ 5%, fibre ireme ryibisanzwe ntabwo ridahuye. .
7. Igisubizo cya CMC cyamazebwe na calcium, magnesium, hamwe numunyu umwe, nta mvura yameneka, ariko viscosiya igisubizo cya CMC kizagabanuka.
8. Niba ibisabwa uruhushya, gerageza mu buryo butaziguye ibisubizo bitangaje bya selile ether no kugereranya umubare wo kugumana amazi ya selile ya selile elt.
