Mayelana ne-hydroxypropyl methylcellulose ngesikhathi sokusebenzisa i-putty powder

1. Izinkinga ezivamile ku-putty powder

[Ukomiswa ngokushesha] Lokhu ikakhulukazi kuhlobene nenani lomlotha we-calcium powder ongezwe (likhulu kakhulu, linganciphisa ngokufanelekile inani lempushana yomlotha we-calcium esetshenziswa kufomula ye-putty) kanye nezinga lokugcinwa kwamanzi le-hydroxypropyl methylcellulose (HPMC), futhi ihlobene futhi Ihlobene nokoma kodonga.

[Ukwesulwa nokugoqa] Lokhu kuhlobene nezinga lokugcinwa kwamanzi. I-Hydroxypropyl methylcellulose (HPMC) ine-viscosity ephansi futhi ijwayele lesi simo noma inani lokungezwa lincane.

[Ukususwa kwempuphu ye-putty yodonga lwangaphakathi] Lokhu kuhlobene nenani le-ash calcium powder eyengeziwe (inani lomlotha we-calcium powder ku-putty formula lincane kakhulu noma ubumsulwa be-ash calcium powder buphansi kakhulu, kanye nenani lomlotha. I-calcium powder ku-putty powder formula kufanele inyuswe ngendlela efanele) Ngesikhathi esifanayo, iphinde ihlotshaniswe nenani kanye nekhwalithi ye-hydroxypropyl methylcellulose (HPMC), ebonakala ngenani lokugcinwa kwamanzi lomkhiqizo. Izinga lokugcinwa kwamanzi liphansi, futhi i-calcium oxide ku-ash calcium powder ayitholi ngokugcwele i-Calcium hydroxide conversion hydration) isikhathi asanele, esibangelwa.

[Amabhamuza] Lokhu kuhlobene nokuswakama okomile kanye nokucaba kodonga, futhi kuhlobene nokwakhiwa.

[Kuvela amaphuzu ephini] Lokhu kuhlobene ne-cellulose, enezakhiwo ezingezinhle zokwakha ifilimu, futhi nokungcola okuku-hydroxypropyl methylcellulose (HPMC) kusabela kancane ngomlotha we-calcium. Uma ukusabela kunzima, i-putty powder izobonakala i-tofu Slag state. Ayikwazi ukufakwa odongeni, futhi ayinakho amandla ahlangene ngesikhathi esifanayo. Ngaphezu kwalokho, imikhiqizo efana ne-hydroxypropyl methylcellulose (HPMC) exutshwe neqembu le-carboxymethyl nayo ivela kulesi simo.

[Kuvela imihume nezimbobo zezintaba-mlilo] Lokhu ngokusobala kuhlobene nokushuba kwesimo samanzi sesisombululo samanzi se-hydroxypropyl methylcellulose (HPMC). Ukungezwani kwetafula lamanzi kwesisombululo samanzi se-hydroxyethyl akubonakali. Kungaba kuhle ukwenza ukwelashwa kokuqeda.

[I-putty kulula ukuqhekeka futhi ibe phuzi ngemva kokoma] Lokhu kuhlobene nokwengezwa kwenani elikhulu lempushana yomlotha we-calcium. Uma inani le-ash calcium powder lengezwa kakhulu, ubulukhuni be-putty powder buzokhula ngemva kokumisa. Ubulukhuni kuphela obungenakho ukuguquguquka buzoqhekeka kalula, ikakhulukazi Kungenzeka ukuthi uqhekeke uma ungaphansi kwamandla angaphandle. Ibuye ihlotshaniswe nokuqukethwe okuphezulu kwe-calcium oxide ku-ash calcium powder.

2. Kungani i-putty powder iba mncane ngemva kokwengeza amanzi?

IHydroxypropyl methylcellulose (HPMC) isetshenziswa njenge-ejenti ejiya futhi egcina amanzi kumafutha. Ngenxa ye-thixotropy ye-hydroxypropyl methylcellulose (HPMC), i-hydroxypropyl methylcellulose ku-putty powder Ukwengezwa kwe-HPMC nakho kubangele i-thixotropy ngemva kokwengeza amanzi ku-putty. Le thixotropy ibangelwa ukubhujiswa kwesakhiwo esihlanganisiwe esikhululekile sezingxenye ku-putty powder. Lesi sakhiwo sivuka ekuphumuleni futhi siphuka ngaphansi kokucindezeleka. Okusho ukuthi, i-viscosity iyancipha ngaphansi kokugqugquzela, futhi i-viscosity iyalulama lapho imile.

3. Yisiphi isizathu esenza ukuthi i-putty ibe nzima kakhulu ekukhunjweni?

Kulokhu, i-viscosity ye-hydroxypropyl methylcellulose (HPMC) evame ukusetshenziswa iphezulu kakhulu, futhi abanye abakhiqizi basebenzisa amayuan angama-200,000 ukwenza i-putty. I-putty ekhiqizwa ngale ndlela ine-viscosity ephezulu, ngakho izocwila lapho i-batch ikhuhla. umuzwa we. Inani elinconyiwe le-putty yezindonga zangaphakathi yi-3-5 kg, futhi i-viscosity yi-80,000-100,000.

4. Kungani uzwa sengathi i-viscosity ye-hydroxypropyl methylcellulose (HPMC) ene-viscosity efanayo ihlukile ebusika nasehlobo?

Ngenxa ye-gelation eshisayo yomkhiqizo, i-viscosity ye-putty ne-mortar izokwehla kancane kancane ngokunyuka kwezinga lokushisa. Lapho izinga lokushisa lidlula izinga lokushisa lejeli lomkhiqizo, umkhiqizo uzodonswa emanzini futhi ulahlekelwe yi-viscosity yawo. Izinga lokushisa lekamelo ehlobo livame ukuba ngaphezu kwama-degree angu-30, okuhluke kakhulu ekushiseni kwasebusika, ngakho-ke i-viscosity iphansi. Kunconywa ukukhetha umkhiqizo one-viscosity ephakeme uma usebenzisa umkhiqizo ehlobo, noma ukwandisa inani le-hydroxypropyl methylcellulose (HPMC), nokukhetha umkhiqizo onezinga lokushisa eliphezulu lejeli.
