Iingxaki zeClassic nge-hydroxypropyl methyl seluplose

1. Sisiphi esona sicelo siphambili se-hydroxypropyl methylcelculose (HPMC)?
I-HPMC isetyenziswa ngokubanzi kwizixhobo zokwakha, iingubo, i-reatsins, i-ceramic, i-ceramics, ukutya, izibalo, i-cosmetics, amanye amashishini. I-HPMC inokwahlulwa ibe yeyaba kwinqanaba lokwakha, inqanaba lokutya kunye namayeza ngokwenjongo. Okwangoku, uninzi lweemveliso zasekhaya libakala lokwakha. Kwinqanaba lokwakha, i-popy powder isetyenziswa kwisixa esikhulu, malunga ne-90% isetyenziselwa umgubo ongezantsi, kwaye ezinye zisetyenziselwa ukhula lwesamente.

2. Yintoni ivumba le-hydroxypropyl methylcelcelculose (i-HPMC)?
I-HPMC eveliswa yindlela ye-Solvent isebenzisa i-toluene kunye ne-isopropanol njengamanyibilikisi. Ukuba ukuhlamba akulunganga kakhulu, kuya kubakho iphunga eligqithisiweyo.

3. Zithini iindlela zokuchithwa kwe-hydroxypropyl methylcelcelgalose (HPMC)?
Indlela eshushu yokuphelisa amanzi Iindlela ezimbini eziqhelekileyo zichazwe ngolu hlobo lulandelayo:
1) Beka inani elifunekayo lamanzi ashushu kwisitya kwaye asitshise malunga nama-70 ° C. I-hydroxypropyl methylcelcelsele yongezwa ngokuthe ngcembe, ekuqaleni i-HPMC inyibilikiswe kumphezulu wamanzi, emva koko yayiphoswa kancinci i-sloring.
2), Yongeza i-1/3 okanye i-2/3 yexabiso elifunekayo lamanzi kwisitya, kwaye usitshise ukuya kwi-70 ° C, ukusasaza i-HPMC ngokwesilayidi esishushu; Emva koko yongeza inani elisele lamanzi abandayo ukuya kumanzi ashushu amanzi amdaka, umxube wapholwa emva kokuvuselela.

Indlela yokuxuba i-powder I-Supick Powder kunye nabavelisi bodaka basebenzisa le ndlela. [Hydroxypropyl Methylcelceltulose (HPMC) isetyenziswa njenge-arhente yokugcina amanzi kunye nokugcinwa kwamanzi kwi-sty powder farser. ]

4. Ungawugweba njani umgangatho we-hydroxypropyl methylcelculose (i-HPMC) ngokulula nangokuthathelayo?
. Nangona kunjalo, uninzi lweemveliso ezilungileyo lube mhlophe mhlophe.
. Uninzi lwe-HPMC luveliswe eHebei yi-80 mesh. Ukuhlehlisa, ngokuchaseneyo, kungcono.
. Okukhona ugqithisele ngakumbi ukuhambisa, engcono, ebonisa ukuba kukho ukungavumi okuncinci kuyo. . Ukutshintsha kweesanda ezithe nkqo zihlala zilungile, kwaye oko kubi kakhulu, kodwa oko akuthethi ukuba umgangatho wokuphendula ngokuthe nkqo ubhetele kuneso sezinto ezininzi.
. Ubungqina bukhulu, ngokubanzi ngenxa yokuba umxholo weqela le-hydroxypropy kuyo kuphezulu, kwaye umxholo weqela le-hydroxypropy iphezulu, ukugcinwa kwamanzi kungcono.

5. Nguwuphi umahluko phakathi kohlobo olubandayo lwaManzi oluBandayo kwangoko kunye nohlobo olunyibilikayo lwe-hydroxypropyl methylcelcelcelcelceluplose kwinkqubo yemveliso?
Uhlobo lokusasazeka okukhawulezayo lwe-HPMC luphathwe umphezulu neGlyoxal, kwaye iyasasaza ngokukhawuleza emanzini abandayo, kodwa ayinyibiliki. Inyibilikisa kuphela xa uVekyusi uyanda. Uhlobo lwethutyana alunawo unyango lomphezulu nge-glyoxal. Ukuba isixa se-glyngoxal sikhulu, ukusasazeka kuya kukhawuleza, kodwa i-vickosity iya kukhula kancinci, kwaye ukuba isixa sincinci, okuchaseneyo kuya kuba kuyinyani.

6. Luthini uVekyusis ofanelekileyo we-hydroxypropyl methylcelcellulose (HPMC)?
I-podty powder ibingama-100,000 Yuan, kwaye iimfuno zodaka ziphezulu, kwaye i-150,000 yuan iyafuneka ukuze isetyenziswe ngokulula. Ngaphezu koko, owona msebenzi ubalulekileyo we-HPMC yindawo yokugcina amanzi, ilandelwe ngokutyibilika. Kumgubo obekelweyo, lo gama nje ukugcinwa kwamanzi kulungile kwaye i-vickosity iphantsi (70,000-80,000), kunokwenzeka. Ewe, ukuphakama okuphezulu, okungcono ukugcinwa kwamanzi. Xa uVeksity engaphezulu kwe-100,000, uVekyusi uya kuchaphazela ukugcinwa kwamanzi. Hayi imali kwakhona.

7. Zeziphi izikhombisi eziphambili ze-hydropylpropyl methylcelculose (HPMC)?
Umxholo weHydroxypropy kunye noVeksity, uninzi lwabantu luxhalabile ngezi zikhombisi zimbini. Abo banomxholo ophezulu we-hydroxypropy ngokubanzi banogcino lwamanzi olungcono. Lowo une-viscosity ephezulu unyanzelekile ukuba ugcinwe ngaphezulu, ngokulinganayo (hayi ngokupheleleyo), kunye nalowo unee-viscofity ephezulu esetyenziswe ngcono ekwanje.

8. Zeziphi izixhobo eziphambili ze-hydroxypropyl methylcelcelcelce (i-HPMC)?
Ezona zinto ziphambili ze-Hydroxypropyl Methylcelcelculose (HPMC): I-HPMC ye-HPMC, i-methyl hloride, i-propylene oxide, i-supec, i-tooda, isopropanol, njl.

9. Nguwuphi umsebenzi ophambili wokusetyenziswa kwe-HPMC kwi-potty powder, kwaye kwenzeka ngokukhawuleza?
Kwibhontsi ye-Putty, i-HPMC idlala iindima ezintathu zokugcina amanzi, ukugcinwa kwamanzi kunye nokwakha amanzi kunye nokwakha amanzi.

Ukutyibilika: I-seluplose inokuba yinto etyibilikayo ukuyinqumamisa kwaye igcine isisombululo iyuniform inyuke kwaye iphantsi, kwaye ixhathise i-ig.
Ukugcinwa kwamanzi: Yenza umgubo obekwe kancinci, kwaye uncede i-ASH Calcium ukuba iphendule phantsi kwesenzo samanzi.
Ulwakhiwo: I-Seleculose inefuthe lokuthambisa, elinokwenza umgubo obekiweyo onokwakha kakuhle.

Ukongeza amanzi kumbhobho wokungeniswa kwaye uyibeke eludongeni yindlela yokuphendula yemichiza, kuba kusenziwa izinto ezintsha. Ukuba ususa umgubo odongwe eludongeni eludongeni, gxotha ube ngumgubo, kwaye uyisebenzise kwakhona, ayiyi kusebenza kuba izinto ezintsha (i-calcium carbonate) zenziwe. ) nayo.

Izinto eziphambili ze-Ash Calcium Powder zezi: umxube we-CA (oh) 2, i-cao kunye ne-COOS ESHORCUM ivelisiwe, i-CAO HOORE: I-COO HOORE kuphela I-calcium, kwaye ayithathi nxaxheba kuyo nayiphi na impendulo ngokwayo.

I-10. I-HPMC yi-ionic seluplose ether, ke yeyiphi i-non-ionic?

Kwimigaqo ye-walaman, i-ions zizinto ezingasebenziyo emanzini. I-ioris ibhekisa kwinkqubo apho i-electrolyte ihluthwe kwii-Ions ezinokuhamba ngokukhululekileyo kwi-Solvent ekhethekileyo (njengamanzi, utywala). Umzekelo, i-sodium chloride (i-NACL), ityuwa esiyitya yonke imihla, inyibilikiswe emanzini kwaye i-Ionid ukuvelisa i-Ions ye-sodium esuswe ngokukhululekileyo kunye ne-chloride i-ions (CLI) ezihlawuliswa kakubi. Oko kukuthi, xa i-HPMC ifakwe emanzini, ayiyi kukhokelela kwi-Ions, kodwa ikho ngohlobo lweeMolekyuli.

11. Ithini iqondo lokushisa le-gene le-hydroxypropyl methylcelcelcelcelcelose ehambelana nayo?
Iqondo lokushisa le-HPMC lihambelana nomxholo wayo we-FOFMCY, iphantsi komxholo wendlela, iqondo lobushushu.

12. Ngaba lukhona ubudlelwane phakathi kwethontsi lomgubo we-potty kunye ne-HPMC?
I-powder ilahleko yomgubo wokubeka ihambelana ikakhulu kumgangatho we-ASH Calcium, kwaye ingenanto yokwenza ne-HPMC. Umxholo we-calcium ophantsi ye-calcium engwevu kunye nomyinge oqinisekileyo we-cao kunye ne-2 kwi-2 kwi-clecium ye-grey ye-grey iya kubangela ilahleko yomgubo. Ukuba inento yokwenza ne-HPMC, ke ukuba i-HPMC inelungelo lamanzi ahlwempuzekileyo, iya kubangela ilahleko yomgubo.

13. Nguwuphi umahluko phakathi kohlobo olubandayo lwaManzi oluBandayo kwangoko kunye nohlobo olunyibilikayo lwe-hydroxypropyl methylcelcelcelcelcelgalose kwimveliso yemveliso?
Uhlobo lokusasazeka okukhawulezayo lwe-HPMC luphathwe umphezulu neGlyoxal, kwaye iyasasaza ngokukhawuleza emanzini abandayo, kodwa ayinyibiliki. Inyibilikisa kuphela xa uVekyusi uyanda. Uhlobo lwethutyana alunawo unyango lomphezulu nge-glyoxal. Ukuba isixa se-glyngoxal sikhulu, ukusasazeka kuya kukhawuleza, kodwa i-vickosity iya kukhula kancinci, kwaye ukuba isixa sincinci, okuchaseneyo kuya kuba kuyinyani.
