Hydroxypropyl methylcellse hpmc ubumenyi rusange

1. Niyihe ntego nyamukuru ya HPMC?

Iki gicuruzwa gikoreshwa nkuwabyimbye, usannye, binder, abakuru, gukinisha amavuta, filler, Emalifier, Emalizer na Stabilizer mu nganda. Bikoreshwa kandi muri synthectic resin, petrochemical, ceramic, impapuro, uruhu, imiti, inganda zibi.

2. Ni uruhe ruhare rwa HPMC mubutaka bwimbere?

HPMC ifite imikorere itatu: ifu ya putty kurukuta rwimbere, kubyimba, gufunga amazi no kubaka. Kwibandaho: Methyl selile irashobora kwibandaho no kureremba cyangwa gutangaza igisubizo cyo gukomeza imirimo imwe kandi ihamye no gukumira gutemba no kumanika. Gufunga amazi: Ifu yimbere yimbere yumye buhoro, kandi Calcium yongeyeho igaragarira mugukoresha amazi. Ubwubatsi bwubuhanga: Methyl selile ifite imikorere itose, ishobora gutuma urukuta rwimbere rufite imiterere myiza yubuhanga. HPMC ntabwo yitabira guhindura imiti yose, ariko igira uruhare gusa yo kuzuza. Inner wall putty powder, on the wall, is a chemical change, because there is a new chemical conversion, the inner wall putty powder is removed from the wall, milled, and reused , Because a new chemical substance (calcium bicarbonate) has been produced. Ibice byingenzi byifu ya gray calcium ni: imvange ya ca (Oh) 2, Cao na Caico3 iguye gusa Kandi ntabwo yitabira reaction yose ubwayo.

3. Nigute wacira ireme rya HPMC gusa kandi byanze bikunze?

. Ariko, ibicuruzwa byiza bifite cyera cyiza. . Ibyiza byiza, nibyiza muri rusange. . Imbere, mubyiza, byerekana ko hari ibicucu bike imbere. . Ibijyanye na reactique reaction muri rusange ni byiza, kandi reactOr ya horizontal ni bibi, ariko ntibisobanura ko ubwiza bwa reactique biruta iyo mico itambitse. Ubwiza bwibicuruzwa buracyafite ibintu byinshi. (4) Umubare: nini igipimo, iremereye cyane. Umwihariko mwinshi mubisanzwe biterwa na hydroxyleproppoppopylepylepylepyley, kandi hejuru ya hydroxyPropyle, ni byiza kugumana amazi.

4. Ni iki kigomba kwitabwaho mugihe ukoresheje viscosiya nubushyuhe bwa HPMC?

Uruzinduko rwa HPMC ni kugereranywa mu buryo bubi ku bushyuhe, ni ukuvuga, viscosity yiyongera uko ubushyuhe bugabanuka. Mubisanzwe tuvuga ko viscosiya yibicuruzwa bivuga ibisubizo byo kwipimisha igisubizo cyayo 2% yamazeko ku bushyuhe bwa dogere 20. Mubikorwa bifatika, mubice bifite ubushyuhe bunini bwizuba, ni bwo bukwiye kumenya ko bisabwa gukoresha urusyo ruke mu gihe cy'itumba, kikaba cyiza cyo kubaka. Bitabaye ibyo, iyo ubushyuhe ari buke, vino ya selile iziyongera, kandi ukuboko kuzumva uremereye igihe yakuweho.

5. Ni ubuhe buryo bwo kuvugurura bwa HPMC?

Uburyo bushyushye bwamazi: Kubera ko HPMC idashonga mumazi ashyushye, HPMC irashobora gutatanya rimwe mumazi ashyushye mugihe cyambere, hanyuma ashonga vuba iyo akonje. Uburyo bubiri busanzwe busobanurwa ku buryo bukurikira: 1). Umubare w'amazi ashyushye kandi ugera kuri 70 ° C. Buhoro Ongeraho HydroxyPropyl Methylcellse hamwe no gukangurira buhoro, Tangira HPMC ireremba hejuru y'amazi, hanyuma uzenguruke buhoro buhoro, hanyuma uhagarike buhoro buhoro, kandi ukonjesha uhindagurika. 2). Ongeramo 1/3 cyangwa 2/3 byamazi asabwa mumazi no gushyushya kugeza 70 ° c. Ukurikije uburyo bwa 1), gutatanya hpmc gutegura amazi ashyushye; Noneho ongeramo umubare usigaye wamazi akonje kumazi ashyushye mumazi, akonje kuvanga nyuma yo kubyutsa. Uburyo bwo kuvanga powder: Kuvanga ifu ya HPMC hamwe nibindi bikoresho byifu, kuvanga neza, kuko buri mfuruka yo gushonga, kuko buri nkoni ya HPMC ishonga ako kanya iyo yujuje amazi. -Gukoresha ifu ya farteror hamwe nabakora uburozi bakoresha ubu buryo. . ]

6. Nikidosageya hpmc yongeyeho muri powder ifu?

Umubare wa HPMC ikoreshwa muburyo buratandukanye bitewe nikirere, ubushyuhe, ubwiza bwaho, formulaire ya powder ifu, na "ubuziranenge busabwa nabakiriya". Muri rusange, ni hagati ya kg 4 na 5 kg. Kurugero, ifu ya Putty imbaye imyenda '> Beijing ahanini ahanini 5 kg; Ifu ya Putty muri Guizhou ahanini ahanini ari 5 kg mu cyi na 4.5 kg mu gihe cy'itumba; Amafaranga yongeyeho ya Yunnan ugereranije ni muto, muri rusange 3 kg-4 kg nibindi.
