Umsebenzi we-hydroxypropyl methylcellulose (HPMC) kwi-putty eludongeni

1. Ziziphi iimpawu eziphambili zezobugcisa ze-hydroxypropyl methylcellulose (HPMC)?

Umxholo weHydroxypropyl kunye ne-viscosity, abaninzi abasebenzisi banenkxalabo malunga nezi zikhombisi zimbini.Abo banomxholo ophezulu we-hydroxypropyl ngokubanzi banokugcinwa kwamanzi okungcono.Lowo une-viscosity ephezulu unokugcinwa kwamanzi okungcono, ngokuthelekiswa (kungekhona ngokupheleleyo), kwaye lowo une-viscosity ephezulu isetyenziswe ngcono kwi-cement mortar.

2. Yintoni umsebenzi oyintloko wokusetyenziswa kwe-HPMC kwi-putty powder?
Kwi-putty powder, i-HPMC inemisebenzi emithathu yokuqina, ukugcinwa kwamanzi kunye nokwakhiwa.
Ukutyebisa: Iselulosi inokujiya ukuze inqunyanyiswe kwaye igcine iyunifomu yesisombululo inyuka naphantsi, kwaye imelane nokudodobala.Ukugcinwa kwamanzi: yenza i-putty powder yome kancinci, kwaye uncedise i-calcium yothuthu ukuba isabele phantsi kwesenzo samanzi.Ukwakhiwa: I-Cellulose inefuthe lokuthambisa, elinokwenza ukuba i-putty powder ibe nokwakhiwa kakuhle.

3. Ngaba kukho ubudlelwane phakathi kokuhla kwe-putty powder kunye ne-HPMC?
Ukulahlekelwa ngumgubo we-putty powder kuhambelana ikakhulu nomgangatho we-ash calcium, kwaye ayinanto encinci ne-HPMC.Umxholo we-calcium we-gray calcium kunye nomlinganiselo we-CaO kunye ne-Ca (OH) 2 kwi-gray calcium ayifanelekanga, eya kubangela ukulahleka kwe powder.Ukuba inento yokwenza ne-HPMC, ke ukugcinwa kwamanzi okungahambi kakuhle kwe-HPMC kuya kubangela ukulahlekelwa ngumgubo.

4. Yintoni isixai-hydroxypropyl methylcellulose (HPMC) kwi-putty eludongeniumgubo?
Isixa se-HPMC esisetyenziswe kwizicelo eziphathekayo siyahluka ngokuxhomekeke kwimozulu, ubushushu, umgangatho we-calcium ash ash yendawo, ifomula ye-putty powder kunye "nomgangatho ofunwa ngabathengi".Ngokuqhelekileyo, phakathi kwe-4 kg kunye ne-5 kg.Umzekelo: ininzi ye-putty powder e-Beijing yi-5 kg;ininzi ye-putty powder e-Guizhou yi-5 kg ​​ehlotyeni kunye ne-4.5 kg ebusika;inani le-putty eYunnan lincinci, ngokubanzi i-3 kg ukuya kwi-4 kg, njl.

5. Yintoni i-viscosity efanelekileyo ye-hydroxypropyl methylcellulose (HPMC)?
Ngokubanzi, i-100,000 ye-yuan ye-putty powder yanele, kwaye iimfuno zodaka ziphezulu, kwaye i-150,000 ye-yuan iyafuneka ukuze isetyenziswe lula.Ngaphezu koko, owona msebenzi ubalulekileyo we-HPMC kukugcina amanzi, kulandelwa kukuqina.Kwi-putty powder, ngokude nje ukugcinwa kwamanzi kulungile kwaye i-viscosity iphantsi (70,000-80,000), nayo inokwenzeka.Ngokuqinisekileyo, ukuphakama kwe-viscosity, ngcono ukugcinwa kwamanzi okuhambelanayo.Xa i-viscosity idlula i-100,000, i-viscosity ayinayo impembelelo ekugcinweni kwamanzi.enkulu.

6. Indlela yokukhetha i-hydroxypropyl methylcellulose (HPMC) efanelekileyo ngeenjongo ezahlukeneyo?
Ukusetyenziswa kwe-putty powder: iimfuno ziphantsi, i-viscosity yi-100,000, yanele, into ebalulekileyo kukugcina amanzi kakuhle.Ukusetyenziswa komdaka: iimfuno eziphezulu, i-viscosity ephezulu, i-150,000 ingcono, isicelo seglue: iimveliso ezikhawulezayo ziyafuneka, i-viscosity ephezulu.

7. Ukusetyenziswa kwe-HPMC kwi-putty powder, yintoni isizathu se-bubbles kwi-putty powder?
Kwi-putty powder, i-HPMC idlala iindima ezintathu zokuqina, ukugcinwa kwamanzi kunye nokwakhiwa.Musa ukuthatha inxaxheba kuzo naziphi na iimpendulo.Izizathu zamaqamu:
(1) Beka amanzi amaninzi kakhulu.
