Iyini i-hydroxypropyl methyl cellulose HPMC?

I-HPMC i-hydroxypropyl methyl celluloseumkhiqizi ongumkhiqizi wefekthri umphakeli ngaphandle
Kuyini ukusetshenziswa okuyinhloko kwe-HPMC?
I-HPMC ingahlukaniswa: Ibanga lokwakha, ibanga lokudla kanye nebanga lezokwelapha ngokusetshenziswa.
I-HPMC isetshenziswa kabanzi ezintweni zokwakha, okokugqoka, izinsalela zokwenziwa, izitsha zobumba, imithi, ukudla, izindwangu, ezolimo, izimonyo, ugwayi nezinye izimboni.
Njengamanje, iningi lebanga lokwakhiwa kwasekhaya, ebangeni lokwakha, isilinganiso se-putty powder sikhulu, cishe i-90% isetshenziselwa ukwenza i-putty powder, enye isetshenziselwa ukwenza udaka lukasimende neglue.

Yiziphi izinto zokusetshenziswa eziyinhloko ze-HPMC?
Izinto zokusetshenziswa eziyinhloko ze-HPMC: ukotini ocolisisiwe, i-chloromethane, i-propylene oxide. Ezinye izinto zokusetshenziswa yilezi, ithebhulethi ye-alkali, i-asidi, i-toluene, i-isopropanol nokunye.

- I-HPMC ihlukaniswe yaba izinhlobo eziningana, yimuphi umehluko ekusetshenzisweni?
I-HPMC ingahlukaniswa ngohlobo olusheshayo noluncibilikayo ngokushisa.

Imikhiqizo esheshayo, emanzini abandayo yahlakazeka ngokushesha, yanyamalala emanzini, ngalesi sikhathi uketshezi alunayo i-viscosity, ngoba i-HPMC ivele ihlakazeke emanzini, akukho ukuchithwa kwangempela. Cishe imizuzu emi-2, i-viscosity yoketshezi ikhula kancane kancane, yakha i-viscous colloid esobala. Uhla olubanzi lwesicelo, ku-putty powder nodaka, neglue ewuketshezi nopende, lungasetshenziswa, akukho taboo.

Imikhiqizo encibilikayo eshisayo, emanzini abandayo, ingahlakazwa ngokushesha emanzini ashisayo, inyamalale emanzini ashisayo, lapho izinga lokushisa lehla liye ezingeni elithile lokushisa, i-viscosity ibonakala kancane, kuze kube yilapho kwakheka i-viscous colloid ebonakalayo. Ingasetshenziswa kuphela ku-putty powder nodaka, ku-glue ewuketshezi nopende, kuzoba nesenzakalo seqembu, esingeke sisetshenziswe.

Yiziphi izinkomba zobuchwepheshe eziyinhlokoI-HPMC?
Okuqukethwe kwe-Hydroxypropyl kanye ne-viscosity, abasebenzisi abaningi bakhathazekile ngalezi zinkomba ezimbili.

Okuqukethwe kwe-Hydroxypropyl kuphezulu, ukugcinwa kwamanzi ngokuvamile kungcono.

I-viscosity, ukugcinwa kwamanzi, isihlobo (kodwa hhayi ngokuphelele) nayo ingcono, futhi i-viscosity, odakeni lukasimende sebenzisa kangcono okunye.

Ingakanani i-viscosity efanele i-HPMC?
Iqhaza elibaluleke kakhulu le-HPMC ukugcinwa kwamanzi, okulandelwa ukujiya.
Putty powder ngokuvamile 100000 cps kungaba. Uma nje ukugcinwa kwamanzi kuhle, i-viscosity iphansi (70,000-80000), kungenzeka futhi, yebo, i-viscosity inkulu, ukugcinwa kwamanzi okuhlobene kungcono, lapho i-viscosity ingaphezu kuka-100,000, i-viscosity ine-viscosity. umthelela omncane ekugcinweni kwamanzi.
Imfuneko ku-MORTAR Inde kakhulu, UFUNA IZINKULUNGWANE EZIYI-150 ukuze nje ube muhle ukuyisebenzisa.
Glue isicelo: badinga imikhiqizo esheshayo, viscosity high.
