Umsebenzi we-hydroxypropyl methylcellulose (HPMC) ku-wall putty

1. Yiziphi izinkomba zobuchwepheshe eziyinhloko ze-hydroxypropyl methylcellulose (HPMC)?

Okuqukethwe kwe-Hydroxypropyl kanye ne-viscosity, abasebenzisi abaningi bakhathazekile ngalezi zinkomba ezimbili. Labo abanokuqukethwe okuphezulu kwe-hydroxypropyl ngokuvamile banokugcinwa kwamanzi okungcono. Le ene-viscosity ephezulu inokugcinwa kwamanzi okungcono, uma kuqhathaniswa (hhayi ngokuphelele), futhi leyo ene-viscosity ephezulu isetshenziswa kangcono odakeni lukasimende.

2. Uyini umsebenzi oyinhloko wokusetshenziswa kwe-HPMC ku-putty powder?
Ku-putty powder, i-HPMC inemisebenzi emithathu yokuqina, ukugcinwa kwamanzi 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.

3. Ingabe kukhona ubudlelwano phakathi kokwehla kwe-putty powder ne-HPMC?
Ukulahlekelwa kwe-powder kwe-putty powder kuhlobene kakhulu nekhwalithi ye-ash calcium, futhi akuhlangene kangako ne-HPMC. Okuqukethwe kwe-calcium ye-calcium empunga kanye nesilinganiso se-CaO ne-Ca(OH)2 ku-calcium empunga akufanelekile, okuzodala ukulahleka kwempushana. Uma kunokuthile okuphathelene ne-HPMC, khona-ke ukugcinwa kwamanzi okungekuhle kwe-HPMC kuzophinde kubangele ukulahlekelwa kwempushana.

4. Ingakanani inanii-hydroxypropyl methylcellulose (HPMC) ku-wall puttyimpushana?
Inani le-HPMC elisetshenziselwa izicelo ezisebenzayo liyahlukahluka kuye ngokuthi isimo sezulu, izinga lokushisa, izinga le-calcium yomlotha wendawo, ifomula ye-putty powder kanye "nekhwalithi edingekayo kumakhasimende". Ngokuvamile, phakathi 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.

5. Iyiphi i-viscosity efanele ye-hydroxypropyl methylcellulose (HPMC)?
Ngokuvamile, i-100,000 yuan ye-putty powder yanele, futhi izidingo zodaka ziphezulu, 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 ayinawo umthelela ekugcinweni kwamanzi. enkulu.

6. Ingakhetha kanjani i-hydroxypropyl methylcellulose (HPMC) efanele ngezinhloso ezahlukene?
Ukusetshenziswa kwe-putty powder: izidingo ziphansi, i-viscosity yi-100,000, yanele, into ebalulekile ukugcina amanzi kahle. Isicelo se-Mortar: izidingo eziphezulu, i-viscosity ephezulu, i-150,000 ingcono, ukusetshenziswa kweglue: imikhiqizo esheshayo iyadingeka, i-viscosity ephezulu.

7. Ukusetshenziswa kwe-HPMC ku-putty powder, yisiphi isizathu sama-bubbles ku-putty powder?
Ku-putty powder, i-HPMC idlala izindima ezintathu zokuqina, ukugcinwa kwamanzi kanye nokwakha. Ungabambi iqhaza kunoma yikuphi ukusabela. Izimbangela zamabhamuza:
(1) Faka amanzi amaningi kakhulu.
(2) Ungqimba olungezansi alomile, futhi olunye ungqimba luklwejwa phezulu, futhi kulula ukukhihliza amagwebu.
