Inani le-HPMC elisetshenziselwa izicelo ezisebenzayo liyahlukahluka kuye ngokuthi isimo sezulu, izinga lokushisa, ikhwalithi yendawo ye-ash calcium powder, ifomula ye-putty powder kanye "nekhwalithi edingekayo kumakhasimende". Ngokuvamile, iphakathi kuka-4 kg no-5 kg. Isibonelo: iningi le-putty powder e-Beijing liyi-5 kg; iningi lempushana e-Guizhou lingama-5 kg ehlobo kanye no-4.5 kg ebusika; inani le-putty e-Yunnan lincane kakhulu, ngokuvamile li-3 kg kuya ku-4 kg, njll.
Iyiphi i-viscosity efanelekile ye-hydroxypropyl methylcellulose (HPMC) yokukhiqiza i-putty powder?
I-putty powder ivamise ukuba ngu-100,000 yuan, futhi izidingo zodaka ziphezulu, futhi 150,000 yuan iyadingeka ukuze isetshenziswe kalula. Ngaphezu kwalokho, umsebenzi obaluleke kakhulu we-HPMC ukugcinwa kwamanzi, okulandelwa ukuqina. Ku-putty powder, inqobo nje uma ukugcinwa kwamanzi kuhle futhi i-viscosity iphansi (70,000-80,000), kungenzeka futhi. Yiqiniso, ukuphakama kwe-viscosity, kungcono ukugcinwa kwamanzi okuhlobene. Lapho i-viscosity idlula i-100,000, i-viscosity izothinta ukugcinwa kwamanzi. Akusenani.
Imuphi umsebenzi oyinhloko wokusetshenziswa kwe-HPMC ku-putty powder?
Ku-putty powder, i-HPMC idlala izindima ezintathu zokuqina, ukugcinwa kwamanzi kanye nokwakha.
Ukuqina: I-Cellulose ingajiywa ukuze imise futhi igcine umfaniswano wekhambi phezulu naphansi, futhi imelane nokuwohloka.
Ukugcinwa kwamanzi: yenza i-putty powder yome kancane, futhi usize i-calcium yomlotha ukuba isabele ngaphansi kwesenzo samanzi.
Ukwakhiwa: I-Cellulose inomphumela wokugcoba, ongenza i-putty powder ibe nokwakhiwa okuhle.
I-HPMC ayibambi iqhaza kunoma yikuphi ukusabela kwamakhemikhali, kodwa idlala indima yokusiza kuphela. Ukwengeza amanzi ku-putty powder bese uyibeka odongeni ukusabela kwamakhemikhali, ngoba kwakhiwa izinto ezintsha. Uma ususa i-putty powder odongeni odongeni, uyigaye ibe yimpuphu, futhi uyisebenzise futhi, ngeke isebenze ngoba izinto ezintsha (i-calcium carbonate) zenziwe. ) futhi. 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, i-calcium carbonate ikhiqizwa, kuyilapho i-HPMC igcina amanzi kuphela, isiza ukusabela okungcono kwe-ash calcium, futhi ayihlanganyeli kunoma yikuphi ukusabela ngokwayo.
