Iputty powder–hydroxypropyl methylcellulose

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, ngokulinganayo (kungekhona ngokupheleleyo), kwaye lowo une-viscosity ephezulu isetyenziswe kangcono kwi-samente 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 ubungakanani be-hydroxypropyl methylcellulose (HPMC) kwi-putty powder?

Isixa se-HPMC esisetyenziswa kwizicelo ezisebenzayo siyahluka ngokuxhomekeke kwimozulu, ubushushu, umgangatho wekhalsiyam yothuthu lwendawo, ifomula yeputty powder kunye 'nomgangatho ofunwa ngabathengi'.

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.

2. Xa umaleko ongezantsi ungasomile, omnye umaleko ukhutshiwe phezulu, kwaye kulula ukuphosa amagwebu.
