Inani le-HPMC elisetshenziswa ezisetshenziswayo liyahlukahluka kuye ngesimo sezulu, izinga lokushisa, ikhwalithi yempuphu ye-calcium yomlotha wendawo, ifomula yempuphu ye-putty kanye "nekhwalithi edingekayo ngamakhasimende". Ngokuvamile, liphakathi kuka-4 kg no-5 kg. Isibonelo: iningi lempuphu ye-putty eBeijing lingu-5 kg; iningi lempuphu ye-putty eGuizhou lingu-5 kg ehlobo kanye no-4.5 kg ebusika; inani le-putty eYunnan lincane kakhulu, ngokuvamile lisuka ku-3 kg kuya ku-4 kg, njll.
Iyini i-viscosity efanele ye-hydroxypropyl methylcellulose (HPMC) ekukhiqizweni kwe-putty powder?
Impuphu ye-putty ngokuvamile ingama-yuan ayi-100,000, kanti izidingo ze-mortar ziphakeme, kanti ama-yuan ayi-150,000 ayadingeka ukuze kube lula ukuyisebenzisa. Ngaphezu kwalokho, umsebenzi obaluleke kakhulu we-HPMC ukugcina amanzi, kulandelwe ukujiya. Kumpuphu ye-putty, inqobo nje uma ukugcina amanzi kukuhle futhi i-viscosity iphansi (70,000-80,000), kungenzeka futhi. Vele, uma i-viscosity iphakeme, kungcono ukugcinwa kwamanzi. Lapho i-viscosity idlula i-100,000, i-viscosity izothinta ukugcinwa kwamanzi. Akusekho okuningi.
Uyini umsebenzi oyinhloko wokusetshenziswa kwe-HPMC ku-putty powder?
Ku-putty powder, i-HPMC idlala indima ezintathu zokuqina, ukugcinwa kwamanzi kanye nokwakhiwa.
Ukuqina: I-Cellulose ingaqiniswa ukuze imiswe futhi igcine isisombululo silingana phezulu naphansi, futhi simelane nokuwa.
Ukugcinwa kwamanzi: yenza i-putty powder yome kancane, futhi usize i-calcium yomlotha ukuthi isabele ngaphansi kokusebenza kwamanzi.
Ukwakhiwa: I-Cellulose inomphumela wokugcoba, ongenza i-putty powder ibe nokwakhiwa okuhle.
I-HPMC ayihlanganyeli kunoma yikuphi ukusabela kwamakhemikhali, kodwa idlala indima yokusiza kuphela. Ukwengeza amanzi ku-putty powder bese uyibeka odongeni kuyindlela yokusabela kwamakhemikhali, ngoba izinto ezintsha ziyakhiwa. Uma ususa i-putty powder odongeni, uyigaye ibe yi-powder, bese uyisebenzisa futhi, ngeke isebenze ngoba izinto ezintsha (i-calcium carbonate) sezivele zakhiwe. ) Izingxenye eziyinhloko ze-ash calcium powder yilezi: ingxube ye-Ca(OH)2, i-CaO kanye nenani elincane le-CaCO3, i-CaO H2O=Ca(OH)2—Ca(OH)2 CO2=CaCO3↓ H2O Indima ye-ash calcium ku-CO2 emanzini nasemoyeni Ngaphansi kwalesi simo, kukhiqizwa i-calcium carbonate, kuyilapho i-HPMC igcina amanzi kuphela, isiza ukusabela okungcono kwe-ash calcium, futhi ayihlanganyeli kunoma yikuphi ukusabela ngokwayo.
