Ubukonje buke HPMC: HPMC 400 ikoreshwa cyane cyane murwego rwo kwipimisha, ariko muri rusange itumizwa mu mahanga.
Impamvu: Ubukonje buri hasi, nubwo kubika amazi ari bibi, ariko kuringaniza nibyiza, kandi ubwinshi bwa minisiteri ni bwinshi.
Hagati n'ubukonje buke:hydroxypropyl methylcelluloseHPMC 20000-40000 ikoreshwa cyane cyane kuri tile yometse kuri tile, agent ya caulking, anti-cracking mortar, mortar insulation bonding mortar, nibindi.
Impamvu: gukora neza, kongera amazi make, guhuza minisiteri ndende.
1. Intego nyamukuru ya hydroxypropyl methylcellulose (HPMC) niyihe?
——A: HPMC ikoreshwa cyane mubikoresho byubaka, gutwikira, ibisigazwa byubukorikori, ububumbyi, ubuvuzi, ibiryo, imyenda, ubuhinzi, kwisiga, itabi nizindi nganda. HPMC irashobora kugabanywamo: urwego rwubwubatsi, urwego rwibiryo hamwe nu rwego rwa farumasi ukurikije intego. Kugeza ubu, ibyinshi mubicuruzwa byo murugo ni urwego rwubwubatsi. Mu cyiciro cyubwubatsi, ingano yifu ya putty nini cyane, hafi 90% ikoreshwa mubifu ya putty, naho ibindi bikoreshwa mumasima ya sima na kole.
2. Hariho ubwoko bwinshi bwa hydroxypropyl methylcellulose (HPMC), kandi ni irihe tandukaniro mugukoresha kwabo?
—— Igisubizo: HPMC irashobora kugabanwa muburyo bwubwoko nubwoko bushushe. Ibicuruzwa byubwoko bukwirakwira vuba mumazi akonje bikabura mumazi. Muri iki gihe, amazi ntagira ubwiza, kubera ko HPMC ikwirakwizwa mu mazi gusa kandi nta gushonga nyabyo. Nyuma yiminota igera kuri 2, ubwiza bwamazi bwiyongereye buhoro buhoro, bikora colloid ibonerana. Ibicuruzwa bishonga ubushyuhe, mugihe uhuye namazi akonje, birashobora gukwirakwizwa vuba mumazi ashyushye, bikabura mumazi ashyushye. Iyo ubushyuhe bugabanutse ku bushyuhe runaka (ibicuruzwa byikigo cyacu ni dogere selisiyusi 65), ibishishwa bigenda bigaragara buhoro buhoro kugeza bibaye colloid ibonerana. Ubwoko bushyushye burashobora gukoreshwa gusa mubifu ya pome na minisiteri. Muri kole y'amazi no gusiga irangi, ibintu byo guhuzagurika bizabaho kandi ntibishobora gukoreshwa. Ubwoko bwakanya bufite intera yagutse ya porogaramu. Irashobora gukoreshwa mu ifu yuzuye ifu na minisiteri, kimwe no mu mavuta ya kole no gusiga irangi, nta kubuza kubuza.
3. Ni ubuhe buryo bwo gusesa hydroxypropyl methylcellulose (HPMC)?
—— Igisubizo: Uburyo bwo gushonga amazi ashyushye: Kubera ko HPMC idashonga mumazi ashyushye, HPMC irashobora gukwirakwizwa kimwe mumazi ashyushye mugihe cyambere, hanyuma igashonga vuba iyo ikonje. Uburyo bubiri busanzwe busobanurwa gutya:
1) Shira amazi asabwa muri kontineri hanyuma uyashyuhe kuri 70 ° C. Hydroxypropyl methylcellulose yongeweho buhoro buhoro hamwe no gukurura buhoro, mu ikubitiro HPMC ireremba hejuru y’amazi, hanyuma buhoro buhoro ikora ibibyimba, bikonjeshwa no gukurura.
2), ongeramo 1/3 cyangwa 2/3 byamazi asabwa muri kontineri, hanyuma ubishyuhe kugeza kuri 70 ° C, ukurikije uburyo bwa 1), ukwirakwiza HPMC, utegure amazi ashyushye; hanyuma ongeramo amazi asigaye mumazi ashyushye Muri slurry, imvange yarakonje nyuma yo gukurura.
Uburyo bwo kuvanga ifu: Vanga ifu ya HPMC ninshi mubindi bintu byifu yifu, vanga neza na mixer, hanyuma ushyiremo amazi kugirango ushonga, hanyuma HPMC irashobora gushonga muriki gihe idakomatanye, kuko muri HPMC harimo bike gusa agace gato. Ifu izahita ishonga ihuye namazi. —— Ubu buryo bukoreshwa nifu ya putty nabakora minisiteri. [Hydroxypropyl methylcellulose (HPMC) ikoreshwa nkibintu byabyimbye kandi bigumana amazi muri minisiteri yifu. ]
4. Nigute dushobora gusuzuma ubuziranenge bwa hydroxypropyl methylcellulose (HPMC) byoroshye kandi byihuse?
—— Igisubizo: (1) Kwera: Nubwo umweru udashobora kumenya niba HPMC yoroshye gukoresha, kandi niba urumuri rwongewe mubikorwa, bizagira ingaruka kumiterere yarwo. Nyamara, ibyinshi mubicuruzwa byiza bifite umweru mwiza. (2) Ubwiza: Ubwiza bwa HPMC muri rusange ni mesh 80 na mesh 100, naho mesh 120 ni mike. Hafi ya HPMC ikorerwa muri Hebei ni mesh 80. Nibyiza, nibyiza. . Iyo imiyoboro ihanitse, nibyiza, byerekana ko muri yo harimo ibintu bike bidashonga. Ubucucike bwa reaction ya vertical muri rusange nibyiza, kandi reaction ya horizontal iba mibi, ariko ntidushobora kuvuga ko ubwiza bwa reaction ya vertical iruta iya reaction ya horizontal, kandi hariho ibintu byinshi byerekana ubwiza bwibicuruzwa. (4) Imbaraga rukuruzi: nini nini nini, uburemere nibyiza. Uburemere bwihariye ni bunini, muri rusange kubera ko hydroxypropyl ibirimo iri hejuru, kandi hydroxypropyl irimo, amazi meza ni meza.
5. Ingano ya hydroxypropyl methylcellulose (HPMC) mu ifu yuzuye?
—— Igisubizo: Ingano ya HPMC ikoreshwa mubikorwa bifatika iratandukanye bitewe nikirere, ubushyuhe, ubwiza bwa calcium y ivu ryaho, amata yifu yifu n "ubuziranenge busabwa nabakiriya". Muri rusange, ni hagati ya 4 kg na 5 kg. Kurugero, ibyinshi mubifu byamavuta i Beijing ni kg 5; ifu ya putty muri Guizhou ni kg 5 mu cyi na 4.5 kg mu gihe cy'itumba;
6. Ni ubuhe buryo bukwiye bwa hydroxypropyl methylcellulose (HPMC)?
—— Igisubizo: Ifu yuzuye muri rusange ni 100.000 Yuan, kandi minisiteri irasaba cyane, kandi biroroshye gukoresha 150.000. Byongeye kandi, uruhare runini rwa HPMC ni ukugumana amazi, hagakurikiraho kubyimba. Mu ifu ya putty, mugihe cyose gufata amazi ari byiza kandi ubwiza buri hasi (70.000-80,000), birashoboka. Birumvikana ko ibishishwa biri hejuru, kandi ugereranije no gufata amazi ni byiza. Iyo ibishishwa birenga 100.000, ingaruka zo kwifata mu gufata amazi Ntabwo ari nyinshi.
7. Ni ibihe bimenyetso by'ingenzi bya tekinike ya hydroxypropyl methylcellulose (HPMC)?
—— Igisubizo: Hydroxypropyl ibirimo hamwe nubwiza, abakoresha benshi bita kuri ibi bipimo byombi. Iyo hydroxypropyl iri hejuru, niko gufata amazi neza. Ubukonje bwinshi, kubika amazi, ugereranije (aho kuba byimazeyo) neza, hamwe nubwiza bwinshi, gukoresha neza mumabuye ya sima.
8. Ni ibihe bikoresho by'ibanze bya hydroxypropyl methylcellulose (HPMC)?
—— A: Ibikoresho nyamukuru bya hydroxypropyl methylcellulose (HPMC): ipamba itunganijwe, methyl chloride, okiside ya propylene, ibindi bikoresho fatizo birimo flake alkali, aside, toluene, isopropanol, nibindi.
9. Ni uruhe ruhare nyamukuru rwa HPMC mu gukoresha ifu yuzuye, kandi hari chimiya?
—— Igisubizo: HPMC ifite imirimo itatu yo kubyimba, kubika amazi no kubaka ifu yuzuye. Kubyimba: Cellulose irashobora kubyimba kugirango ihagarike, igumane igisubizo kimwe kandi gihamye, kandi irinde kugabanuka. Kubika amazi: Kora ifu ya putty yumye buhoro, kandi ufashe reaction ya calcium yivu munsi yamazi. Ubwubatsi: Cellulose igira amavuta yo kwisiga, ishobora gutuma ifu ya putty igira imikorere myiza. HPMC ntabwo yitabira imiti iyo ari yo yose kandi igira uruhare gusa. Ongeramo amazi kumifu ya putty ukayishyira kurukuta ni reaction ya chimique. Kubera imiterere yibintu bishya, fata ifu ya putty kurukuta kurukuta, uyisya ifu, hanyuma wongere uyikoreshe. Ntabwo bizakora, kubera ko hashyizweho ibintu bishya (calcium karubone). ) hejuru. Ibice byingenzi bigize ifu ya calcium yivu ni: imvange ya Ca (OH) 2, CaO hamwe na CaCO3 nkeya, CaO + H2O = Ca (OH) 2 —Ca (OH) 2 + CO2 = CaCO3 ↓ + H2O Kalisiyumu yivu mumazi numwuka Mubikorwa bya CO2, karubone ya calcium ikorwa, mugihe HPMC igumana amazi gusa kandi igafasha kwitwara neza kwa calcium yivu, kandi ntabwo yitabira reaction ubwayo.
10. HPMC ntabwo ari ionic selulose ether, none non-ionic niki?
- Igisubizo: Mu magambo y’abalayiki, non-ion ni ibintu bidatera ioni mumazi. Ionisation bivuga inzira electrolyte igabanyijemo ion zigenda zidegembya mumashanyarazi yihariye (nk'amazi, inzoga). Kurugero, sodium chloride (NaCl), umunyu uribwa burimunsi, ushonga mumazi na ionize kugirango ubyare sodium yimuka yubusa (Na +) yishyurwa neza na ion ya chloride (Cl) zishishwa nabi. Ni ukuvuga, iyo HPMC ishyizwe mumazi, ntabwo yigabanyamo ion zashizwemo, ahubwo ibaho muburyo bwa molekile.
