I-HPMC ne-putty powder

1. Uyini umsebenzi oyinhloko wokusetshenziswa kwe-HPMC ku-putty powder? Ingabe kukhona ukusabela kwamakhemikhali?

——Impendulo: 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 nokuyibeka 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 zempushana ye-ash calcium 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.

2. Iyini inani le-HPMC elingezwe ku-putty powder?

——Impendulo: Inani le-HPMC elisetshenziswa ekusebenzeni okungokoqobo liyahlukahluka kuye ngokuthi isimo sezulu, izinga lokushisa, izinga le-calcium yomlotha wendawo, ifomula ye-putty powder kanye “nekhwalithi edingwa amakhasimende”. Ngokuvamile, phakathi kuka-4 kg no-5 kg. Isibonelo: iningi le-putty powder e-Beijing liyi-5 kg; impushana eningi eGuizhou ingu-5 kg ​​ehlobo no-4.5 kg ebusika; inani le-putty e-Yunnan lincane kakhulu, ngokuvamile li-3 kg kuya ku-4 kg, njll.

3. Iyini i-viscosity efanele ye-HPMC ku-putty powder?

——Impendulo: Ngokuvamile, ama-yuan angu-100,000 anele kumpushana we-putty, futhi izidingo zodaka ziphakeme, futhi 150,000 yuan iyadingeka ukuze isetshenziswe kalula. Ngaphezu kwalokho, umsebenzi obaluleke kakhulu we-HPMC ukugcinwa kwamanzi, okulandelwa ukujiya. 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.

4. Kungani i-putty powder igwebu?

——Impendulo: I-Phenomenon: amabhamuza akhiqizwa phakathi nenqubo yokwakha futhi ngemva kwesikhathi esithile, ingaphezulu le-putty liyaqhuma.

imbangela:

1. Isisekelo simaholoholo futhi isivinini sokuplasta siyashesha kakhulu;

2. Isendlalelo se-putty esakhiweni esisodwa sikhulu kakhulu, sikhulu kuno-2.0mm;

3. Umswakama ophansi kakhulu uphezulu kakhulu, futhi ukuminyana kukhulu kakhulu noma kuncane kakhulu.

4. Ngemuva kwesikhathi sokwakhiwa, ukuqhuma nokukhipha amagwebu ebusweni ikakhulukazi kubangelwa ukuxuba okungalingani, kuyilapho i-HPMC idlala indima ekugcineni amanzi, ukuqina nokuthuthukisa ukusebenza ku-putty powder, futhi ayihlanganyeli kunoma yikuphi ukusabela.

5. Iyini isizathu sokukhishwa kwempuphu ye-putty powder?

——Impendulo: Lokhu kuhlobene kakhulu nenani nekhwalithi ye-calcium empunga engeziwe. I-calcium ephansi ye-calcium empunga kanye nesilinganiso esingalungile se-CaO ne-Ca(OH)2 ku-calcium empunga kuzodala ukukhishwa kwempushana. Ngesikhathi esifanayo, ihlobene ne-HPMC. Izinga lokugcinwa kwamanzi liphansi, futhi isikhathi se-ash calcium hydration asanele, okuzophinde kubangele ukukhishwa kwe-powder.

6. Kungani i-putty isindayo ohlelweni lokukhuhla?

——Impendulo: Kulokhu, i-viscosity ye-cellulose esetshenziswa ngokuvamile iphezulu kakhulu. Abanye abakhiqizi basebenzisa i-cellulose engu-200,000 ukwenza i-putty. I-putty ekhiqizwa ngale ndlela ine-viscosity ephezulu, ngakho izwa isindayo uma ikhuhla. Inani elinconyiwe le-putty powder ezindongeni zangaphakathi yi-3-5 kg, futhi i-viscosity yi-80,000-100,000.
