Ibiranga HPMC muri minisiteri yumye

1. Ibiranga HPMC muri minisiteri isanzwe

HPMC ikoreshwa cyane nkumuti wa rearger na mazi bagushingwa namazi muri sima ugereranije. Mu bice bifatika na minisiteri, birashobora guteza imbere virusi n'ingabo, gushimangira imbaraga zifatanije, kugenzurwa na sima yo kugenzura igihe, no kunoza imbaraga zambere n'imbaraga zinyuranye. Kuberako ifite imikorere yo kuguma amazi, irashobora kugabanya gutakaza amazi ku buso bwa beto, irinde ibice kuruhande, no kuzamura imitekerereze nimikorere yubwubatsi. Cyane cyane mubwubatsi, igihe cyo gushyiraho kirashobora kwaguka no guhinduka. Hamwe no kwiyongera kwa HPMC, hazagushiraho igihe cya minisiteri bizaguka byakurikiranye; Kunoza amabuye no guhubuka, bikwiranye nubwubatsi bukoreshwa; Gutezimbere imikorere yubwubatsi kandi bigirire akamaro ubuso bwubaka irinda ikirere cyumyuga.

2. Ibiranga HPMC muri minisiteri idasanzwe

HPMC ni umukozi ushinzwe amazi menshi kumurima wumye minisiteri yumye, bigabanya urugero rwo kuva amaraso no gucyasi bya minisiteri kandi biteza imbere ubumwe bwa minisiteri. Nubwo HPMC igabanya gato imbaraga zihinduka kandi zitera imbogamizi za minisiteri, irashobora kongera imbaraga nimbaraga za minisiteri. Byongeye kandi, HPMC irashobora kubuza neza gushinga ibice bya pulasitike muri minisiteri no kugabanya urutonde rwa plastike ya minisiteri. Kugumana amazi yo kwiyongera no kwiyongera kwa visosi ya HPMC, kandi iyo ubushyuhe bumaze kurenga 100000mpa · s, kugumana amazi ntabwo byiyongereye cyane. Ibyiza bya HPMC nabyo bigira uruhare runini kuri kamwe ka minisiteri. Iyo uduce dufite impumuro, umubare wogumana amazi wa minisiteri uratera imbere. Ingano ya HPMC isanzwe ikoreshwa kuri sima ikwiye kuba munsi ya microns 180 (80 mesh ya ecran). Igipimo gikwiye cya HPMC mumasatsi yumye ni 1 ‰ ~ 3 ‰.

2.1. Nyuma ya HPMC imaze guseswa mumazi, ikwirakwizwa ryingirakamaro kandi rimwe mugabanywa ibikoresho byahinduwe muri sisitemu byemejwe kubera ibikorwa byo hejuru. Nka colloid ikingira, HPMC "ipfundo" ibice bikomeye kandi ikora igice hejuru yubuso bwacyo. Igice cya Filime yoroheje ituma sisitemu ya mirtar ihamye neza, kandi inazamura amazi ya minisiteri mugihe cyo kuvanga no kwihitiramo.

2.2. Bitewe n'imiterere yabyo, igisubizo cya HPMC gituma amazi yo muri minisiteri ataroroshye gutakaza, kandi arekura buhoro buhoro igihe kirekire, ashyikirize minisiteri no kugumana amazi meza no kubaka. Irashobora kubuza amazi atemba vuba kuva kuri minisiteri kugera kuri minisiteri, kugirango amazi aguma hejuru yibikoresho bishya, bishobora guteza imbere hydration ya sima kandi itezimbere imbaraga zanyuma. By'umwihariko niba interineti ihura na sima ya sima, plaster, no kumuzitizi itakaza amazi, iki gice ntigifite imbaraga kandi nta mbaraga zifatanije. Muri rusange, ubuso burahuza nibi bikoresho ni ababitangaza, byinshi cyangwa bike bikurura amazi yo hejuru, bituma habaho imisozi ituzuye kandi bituma habaho verot ram.

Mugutegura minisiteri, kugumana amazi ya HPMC ni imikorere nyamukuru. Byagaragaye ko kugumana amazi bishobora kuba hejuru ya 95%. Ubwiyongere bw'uburemere bwa HPMC kandi bwiyongereyeho umubare wa sima buzatezimbere kugumana amazi n'imbaraga z'umuryango.

Urugero: Kubera ko ubumwe bufite imbaraga zigomba kugira imbaraga ndende zombi hagati ya substrate na tile, ingufu zigira ingaruka ku baguzi b'amazi ava mu nkomoko ebyiri; hejuru (urukuta) hejuru n'amabati. Cyane cyane kuri tile, ireme iratandukanye cyane, bamwe bafite insunga nini, kandi amabati afite igipimo kinini cyamazi, asenya imikorere ihuza. Umukozi ugumana amazi ni ngombwa cyane, kandi yongeyeho HPMC irashobora kubahiriza iki gisabwa.

2.3. HPMC ihamye aside na alkali, hamwe nigisubizo cyacyo gihamye cyane murwego rwa PH = 2 ~ 12. Amazi ya Caustic Soda na Lime ntacyo afite ku mikorere yacyo, ariko alkali irashobora kwihutisha iseswa ryayo kandi ryongerera ubuyobe.

2.4. Imikorere yubwubatsi ya minisiteri yongeweho HPMC yateye imbere cyane. Umuryango usa naho "oily", ushobora gutuma urukuta rwuzuye, rworokora uburebure cyangwa amatafari hamwe ninsanganyamatsiko yo gukomera, kandi irashobora kurambagira umwanya munini, kandi bikwiranye nubwubatsi bunini.

2.5. HPMC nigikoresho cya electrolyte na polymeric, bihamye cyane mubisubizo byiminyururu na electrolytes na electrolytes, kandi birashobora kongerwaho ibikoresho byo kubaka igihe kirekire kugirango bibeho neza.
