Ubukonje buke: 400 bukoreshwa cyane cyane murwego rwo kwipimisha, ariko muri rusange bitumizwa mu mahanga.
Impamvu: Ubukonje buke, kubika amazi nabi, ariko ibintu byiza biringaniye, ubwinshi bwa minisiteri.
Ubucucike buciriritse kandi buke: 20000-40000 bikoreshwa cyane cyane kumatafari ya tile, agent ya caulking, anti-crack mortar, minisiteri yubushyuhe bwa minisiteri, nibindi.
Impamvu: Gukora neza, amazi make yongeweho, hamwe nubucucike bwa minisiteri.
1. Ni ubuhe buryo bukoreshwa bwa hydroxypropyl methylcellulose (HPMC)?
——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 imikoreshereze.Kugeza ubu, ibicuruzwa byinshi murugo ni urwego rwubwubatsi.Mu cyiciro cyo kubaka, ifu ya putty ikoreshwa ku bwinshi, hafi 90% ikoreshwa mu ifu ya putty, naho iyindi ikoreshwa muri sima ya sima na kole.
2. Ubwoko bwa hydroxypropyl methylcellulose (HPMC) ni bangahe?Ni ubuhe buryo bakoresha?
——A: HPMC irashobora kugabanywa muburyo bwubwoko nubwoko bushushe.Ibicuruzwa ako kanya bikwirakwira vuba mumazi akonje bikabura mumazi.Amazi ntagifite ubwiza muri iki gihe kuko HPMC ikwirakwizwa mumazi gusa kandi ntabwo yashonga.Nyuma yiminota igera kuri 2, ubwiza bwamazi bugenda bwiyongera buhoro buhoro hanyuma havuka colloid ibonerana.Ibicuruzwa bishyushye birashobora gukwirakwira vuba mumazi ashyushye bikabura mumazi ashyushye mugihe uhuye namazi akonje.Iyo ubushyuhe bugabanutse kugera ku bushyuhe runaka (ibicuruzwa by'isosiyete yacu ni dogere selisiyusi 65), ibishishwa bigenda bigaragara buhoro buhoro kugeza igihe ibinyabuzima biboneye biboneye.Ubwoko bushyushye burashobora gukoreshwa gusa kubifu ya poro na minisiteri.Muri kole yamazi no gusiga irangi, guhuzagurika bizabaho kandi ntibishobora gukoreshwa.Ubwoko bwihuse bufite intera yagutse ya porogaramu.Irashobora gukoreshwa kubifu ya poro, minisiteri, kole yamazi, no gusiga irangi nta kubuza.
3. Nubuhe buryo bwo gushonga hydroxypropyl methylcellulose (HPMC)?
—— Igisubizo: Uburyo bwo gushonga amazi ashyushye: Kubera ko HPMC idashobora gushonga mumazi ashyushye, HPMC irashobora gukwirakwizwa neza mumazi ashyushye mugihe cyambere hanyuma igashonga vuba nyuma yo gukonja.Uburyo bubiri busanzwe bwasobanuwe hano hepfo:
1) Shira amazi asabwa mubikoresho hanyuma ubishyuhe kugeza kuri 70 ℃.Buhoro buhoro ongeramo hydroxypropyl methylcellulose hamwe no gukurura buhoro.Mu ikubitiro HPMC ireremba hejuru y’amazi, hanyuma igenda ikora buhoro buhoro, hanyuma ikonjesha.
2).Ongeramo 1/3 cyangwa 2/3 by'amazi asabwa muri kontineri, shyushya kuri 70 ° C, ukwirakwiza HPMC ukurikije uburyo muri 1), hanyuma utegure amazi ashyushye;hanyuma ongeramo amazi asigaye asigaye mumazi ashyushye.gutobora mumazi, koga no gukonjesha imvange.
Uburyo bwo kuvanga ifu: Vanga ifu ya HPMC ninshi mubindi bintu byifu yifu, vanga neza na blender, hanyuma ushyiremo amazi kugirango ushonga.Muri iki gihe, HPMC irashobora guseswa kandi ntishobora gufatana hamwe, kuko muri buri gice harimo akantu gato ka HPMC.Inguni nto.Ifu irashonga ako kanya iyo ihuye namazi.—— Ifu yuzuye ifu nabakora minisiteri bakoresha ubu buryo.Hydroxypropyl methylcellulose (HPMC) ikoreshwa nkumubyimba mwinshi kandi ugumana amazi mumashanyarazi ya poro.
4. Nigute dushobora gusuzuma ubwiza bwa hydroxypropyl methylcellulose (HPMC) byoroshye kandi byihuse?
—— Igisubizo: (1) Kwera: Nubwo umweru utagaragaza niba HPMC yoroshye gukoresha, niba urumuri rwongewemo mugihe cyibikorwa, bizagira ingaruka kumiterere yarwo.Nyamara, ibicuruzwa byinshi byiza bifite umweru mwiza..Hafi ya HPMC ikorerwa muri Hebei ni mesh 80.Nibyiza nibyiza nibyiza..Iyo urumuri rwinshi rwinshi, nibyiza, byerekana ko imbere harimo ibintu bidashonga imbere.Ikirere cyimyuka ihanamye muri rusange ni cyiza kuruta icyuma gitambitse, ariko ntidushobora kuvuga ko ubwiza bwa reaktori ihagaze neza kuruta iy'ibikorwa bya horizontal.Hariho ibintu byinshi byerekana ubwiza bwibicuruzwa.(4) Uburemere bwihariye: Ninini nini nini kandi iremereye, nibyiza.Uburemere bwihariye buterwa ahanini na hydroxypropyl yibirimo.Iyo hydroxypropyl iri hejuru, niko gufata amazi neza.
5. Ni ikihe gipimo cya hydroxypropyl methylcellulose (HPMC) mu ifu yuzuye?
—— Igisubizo: Ingano ya HPMC mubikorwa nyabyo iratandukanye ukurikije ikirere, ubushyuhe, ubwiza bwa calcium ya ivu, hamwe na formula yinjiza.ifu ya ty na "ubuziranenge busabwa nabakiriya".Muri rusange, ni hagati ya 4kg na 5kg.Kurugero, ifu yuzuye muri Beijing ni kg 5;ifu yuzuye muri Guizhou ni kg 5 mu cyi na kg 4.5 mu gihe cy'itumba;
6. Ni ubuhe buryo bukwiye bwa hydroxypropyl methylcellulose (HPMC)?
—— Igisubizo: Ifu ya putty muri rusange igura 100.000 Yuan, na minisiteri isaba byinshi, bityo 150.000 yuan birahagije.Kandi umurimo wingenzi wa HPMC nukugumana amazi, ugakurikirwa no kubyimba.Ifu ya putty, mugihe cyose ifite amazi meza hamwe nubukonje buke (70.000-80,000), nibyiza.Birumvikana ko hejuru yubukonje, niko gufata amazi ugereranije.Iyo ibishishwa birenga 100.000, ibishishwa ntacyo bigira ku gufata amazi.
7. Ni ibihe bimenyetso nyamukuru bya tekinike ya hydroxypropyl methylcellulose (HPMC)?
——A: Hydroxypropyl ibirimo hamwe nubwiza, abakoresha benshi bahangayikishijwe nibi bipimo byombi.Iyo hydroxypropyl iri hejuru, niko gufata amazi neza.Hamwe n'ubukonje bwinshi, kubika amazi ni byiza (ntabwo rwose) ari byiza, kandi hamwe nubukonje bwinshi, nibyiza gukoreshwa mumabuye ya sima.
8. Nibihe bikoresho nyamukuru bya hydroxypropyl methylcellulose (HPMC)?
—— A: Ibikoresho nyamukuru bya hydroxypropyl methylcellulose (HPMC): ipamba itunganijwe, methyl chloride, okiside ya propylene, ibindi bikoresho fatizo birimo soda ya caustic, aside, toluene, inzoga ya isopropyl, nibindi.
9. Ni uruhe ruhare nyamukuru rwa HPMC mu gukoresha ifu ya putty?Hoba hari ingaruka z'imiti?
—— Igisubizo: HPMC ifite imirimo itatu yingenzi yo kubyimba, gufata amazi no kubaka ifu yuzuye.Kubyimba: Cellulose irashobora kubyibuha guhagarika, kugumana igisubizo kimwe no kurwanya kugabanuka.Kubika amazi: Kora ifu ya putty yumye buhoro kandi ufashe reaction ya calcium yumukara munsi yamazi.Ubwubatsi: Cellulose igira amavuta kandi irashobora gutuma ifu ya putty ikora neza.HPMC ntabwo yitabira imiti iyo ari yo yose kandi igira uruhare gusa.Iyo ifu ya putty yongewe kumazi hanyuma igashyirwa kurukuta, hazabaho reaction ya chimique.Mugihe habaye ikintu gishya, ifu ya putty kurukuta ikurwa kurukuta hanyuma igahinduka ifu mbere yo kuyikoresha.Ibi ntibikora kuko hashyizweho ibintu bishya (calcium karubone).) hejuru.Ibice byingenzi bigize ifu ya calcium yumukara ni: imvange ya Ca (OH) 2, CaO hamwe na CaCO3 nkeya, CaO + H2O = Ca (OH) 2 -Ca (OH) 2 + CO2 = CaCO3 ↓ + H2O Kalisiyumu yumukara gushonga mu mazi no mu kirere CO2 Mubikorwa bya calcium karubone, HPMC igumana amazi gusa kandi igafasha calcium yumukara kubyitwaramo neza, kandi ntabwo yitabira reaction ubwayo.
10. HPMC ni ether ya selile idafite ionic, nonese iyindi itari iyoni?
Igisubizo: Mu magambo y’abalayiki, abatari ion ni ibintu bidateza amazi mu mazi.Ionisiyoneri ni uburyo electrolytike itandukana muri ion zigenda zidegembya mumashanyarazi amwe (urugero, amazi, inzoga).Kurugero, sodium ya chloride (NaCl), umunyu ukoreshwa burimunsi, ushonga mumazi na ionize, bikabyara mobile mobile kubuntu byubusa byitwa sodium ion (Na +) hamwe na chloride ion (Cl).Ni ukuvuga, iyo HPMC ishyizwe mumazi, ntabwo yigabanyamo ion zashizwemo, ahubwo ibaho muburyo bwa molekile.
