Zithini iingxaki eziqhelekileyo ze-hydroxypropyl methylcelcelgalose?

1. Sisiphi esona sicelo siphambili se-hydroxypropyl methylcelculose (HPMC)?

I-Hydroxypropyl Methylcelcelsulose isetyenziswa ngokubanzi kwizixhobo zokwakha, iingubo, i-resings, i-ceramic, i-ceramics, i-cosmetics, icuba kunye namanye amashishini. I-Hydroxypropyl Methylcelceltulose in inqwahlulwa yaya kwibanga lokwakha, iBanga lokutya kunye namayeza ngokwesicelo sayo. Okwangoku, uninzi lweemveliso zasekhaya libakala lokwakha. Kwibanga lokwakha, i-popy powder isetyenziswa kwisixa esikhulu, malunga ne-90% isetyenziselwa umgubo ongezantsi, kwaye okuseleyo kusetyenziselwa ukuqina kwesamente kunye neglue.

2. Zininzi iintlobo ze-hydroxypropyl methylcelculose (i-HPMC), kwaye yintoni umahluko ekusebenziseni kwabo?

I-HPMC inokwahlulwa kuba luhlobo lwethutyana kunye nodidi olushushu. Iimveliso zohlobo kwangoko zisasaza ngokukhawuleza xa zidibana namanzi abandayo kwaye zitshabalale emanzini. Ngeli xesha, ulwelo alunanto yokuba i-HPMC ichithwa njengamanzi ngaphandle kokupheliswa kokwenene. Emva kwemizuzu emi-2, i-viscosity ye-ulwelo ngokuthe ngcembe inyuka, yenza i-viscous ebonakalayo. Iimveliso ezishushu-zinyibilikisa, xa zidibene namanzi abandayo, zinokusasaza ngokukhawuleza emanzini ashushu kwaye zinyamalala emanzini ashushu. Xa iqondo lobushushu liyelela kubushushu obuthile, i-viscofity iya kuvela kancinci ide ibe yi-collous engabonakaliyo. Uhlobo olushushu olushushu lunokusetyenziswa kuphela kwi-podty powder nodaka. Kwiglue yeglue kunye nepeyinti, kuya kubakho i-phenomenong yeqela kwaye ayinakusetyenziswa. Uhlobo lwethutyana lunoluhlu olubanzi lwezicelo. Ingasetyenziselwa umgubo we-potty kunye nodaka, kunye neglue engamanzi kunye nepeyinti, ngaphandle kokuphikisana.

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 yenani elifunekayo lamanzi esi sitya, kwaye sitshise ukuya kwi-70 ° C, ngokwendlela ye-1), ukusasaza i-HPMC ilungisa amanzi amdaka; Emva koko yongeza inani elisele lamanzi abandayo ukuya kumanzi ashushu, umxube wapholwa emva kokuvuselela.

Indlela yokuxuba i-powder I-Supick Powder kunye nabavelisi bodaka basebenzisa le ndlela. [I-HYDROXYPPOPLL methylcelceltulose (i-HPMC) isetyenziswa njenge-tickener kunye nearhente yokugcina amanzi kwi-stod powty farr.]

4. Ungawugweba njani umgangatho we-hydroxypropyl methylcelculose (i-HPMC) ngokulula nangokuthathelayo?

. Nangona kunjalo, uninzi lweemveliso ezilungileyo lube mhlophe mhlophe.

. Ukuhlehlisa, ngokuchaseneyo, kungcono.

. Ukuphakama okuphezulu, okungcono, kubonisa ukuba akukho ntweni incinci 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. Yintoni ubungakanani be-hydroxypropyl methylcelculose (i-HPMC) kwi-powty powder?

Isixa se-HPMC esisetyenziswa kwizicelo ezisebenzayo ziyahluka ngokuxhomekeke kwimozulu, ubushushu, umgangatho we-Ash Calcium, ifomula ye-poty powder kunye "nomgangatho ofunwa ngabathengi". Ngokubanzi, phakathi kwe-4 kg kunye ne-5 kg. Umzekelo: uninzi lwe-powty powder eBeijing yi-5 kg; Uninzi lwe-poty powty powty eGuizhou yi-5 kg ​​ehlotyeni kunye ne-4.5 kg ebusika; Ixabiso le-popy powder eYunnan incinci, ngokubanzi i-3 kg ukuya kwi-4 kg, njl.

6. Luthini uVekyusis ofanelekileyo we-hydroxypropyl methylcelcellulose (HPMC)?

I-podty powder isebenze ngokubanzi i-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 lwabasebenzisi baxhalabile 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. I-HPMC ayithathi nxaxheba kuyo nayiphi na indlela yokuphendula yekhemikhali, kodwa idlala kuphela indima encedisayo. Ukongeza amanzi kumbhobho wokungeniswa kwaye uyibeke eludongeni yindlela yokuphendula yemichiza, kuba kusenziwa izinto ezintsha. Ukuba ususa umgubo odongwe eludongeni eludongeni, gele ube ngumgubo, kwaye uphinde awusebenzise, ​​awuyi kusebenza kuba izinto ezintsha (i-calcium carbonate) ziye zasekwa.). Izinto eziphambili ze-Ash Calcium Powder zezi: umxube we-CA (oh) 2, i-COO TOHCOATE ye-CO2, i-CAO HOO = COAT I-CARCEMP kuphela i-2 + i-COO THIT kuphela ye-ASH 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.
