Ibikorwa bito, bigira uruhare runini mugutezimbere imikorere yo kubaka minisiteri ivanze-zivanze, zirenga 40% yikiguzi cya minisiteri yumye. Byinshi mubirori mumasoko yimbere murugo bitangwa nabashinzwe kubanyamahanga, kandi dosiye yerekana ibicuruzwa nayo itangwa nabatanga isoko. Igiciro cyo kuvanga kwumye kimene kiguma hejuru cyane, kandi biragoye kumenyekanisha Maller isanzwe kandi persterting fartar nini hamwe nurwego runini. Ibicuruzwa byisoko ryimisozi bigenzurwa namasosiyete, kandi abakora minisiteri bavanze ba mirtar bafite inyungu nke kandi zigabanijwe; Gushyira mubikorwa ibintu bibuze ubushakashatsi buringaniye kandi bugenewe, no gukurikiza buhumyi amahanga. Hano, ibyo dusangiye nawe ni, ni uruhe ruhare rwa hydroxypropyl methylcellse mugice rusange cya minisiteri zubashye?
HydroxyPropyl Methylcellse nubu bwoko bwa selile birasohoka no kurya byagendaga byiyongera vuba cyane mumyaka yashize. HydroxyPropyl methylcellse ikozwe mu ipamba inoze nyuma yo kuvura alkalisa na methyl nk'abakozi ba eriviene nk'abakozi ba erivie, havanze selile ivanze ether, ivanze ether yakozwe mu buryo butandukanye. Urwego rwo gusimbuza ni 1.2 ~ 2.0. Imitungo yayo iratandukanye bitewe nigipimo cya uburyo na hydroxyproppopyl. Ibiranga HydroxyPropyl Methylcellse ni nkibi:
1. HydroxyPropyl Methylcellllse irashonga byoroshye mumazi akonje, kandi bizahura nibibazo byo gushonga mumazi ashyushye. Ariko ubushyuhe bwa pelale mumazi ashyushye burenze ivya methyl selile. Kudakemura mumazi akonje nabyo birateye imbere cyane ugereranije na methyl selile.
2. Viscozetity ya hydroxypropyl methylcellse ifitanye isano nuburemere bwa molekile. Uburemere bunini bwa molekile, hejuru cyane. Ubushyuhe bugira ingaruka kandi ku rubyiruko, uko ubushyuhe bwiyongera, vicosity igabanuka. Ariko, ingaruka za viscosity, ubushyuhe buri munsi ya methyl selile. Igisubizo cyacyo kirahagaze mugihe kibitswe mubushyuhe bwicyumba.
3. Kugumana amazi ya hydroxyPropyl methylcellellse biterwa namafaranga yiyongera, ubushyuhe, nibindi, hamwe nigipimo cyamazi cyacyo mumafaranga yinyongera arenze iy Methyl selile.
4. HydroxyPropyl Methylcellsells irahamye aside na alkali, hamwe nigisubizo cyacyo gihamye muburyo bwa PH = 2 ~ 12. Amazi ya Caustic Soda na Lime ntacyo afite ku mikorere yacyo, ariko alkali irashobora kwihutisha iseswa ryayo kandi ryongerera ubuyobe. HydroxyPropyl Methylcellse irahamye muminyuhuri isanzwe, ariko iyo kwibanda ku gisubizo cyumunyu hejuru, viscogity ya hydroxyPropyl methylcellse igisubizo gikunda kwiyongera.
5. Nka Polyvinyl Inzoga, ibikatsi bya Ether, gum yimboga, nibindi
6. HydroxyPropyl Methylcellse ifite enzyme nziza kuruta methycelllllliulose, kandi amahirwe yo gutesha agaciro igisubizo cyayo kiri munsi yubwa methylcellse.
7. AMAFARANGA ya HydroxyPropyl Methylcellse kugirango ubwubatsi bwa minisiteri ari hejuru kurenza uw'inditi.
