HPMC kunye neputty powder

1. Yintoni umsebenzi oyintloko wokusetyenziswa kwe-HPMC kwi-putty powder? Ngaba kukho ukusabela kweekhemikhali?

--Impendulo: Kwi-putty powder, i-HPMC idlala iindima ezintathu zokuqina, 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. I-HPMC ayithathi nxaxheba kuyo nayiphi na intshukumo yeekhemikhali, kodwa idlala indima encedisayo kuphela. Ukongeza amanzi kwi-putty powder kunye nokuyibeka eludongeni kukusabela kweekhemikhali, kuba izinto ezintsha zenziwe. Ukuba ususa i-putty powder eludongeni eludongeni, ugaye ube ngumgubo, kwaye uyisebenzise kwakhona, ayiyi kusebenza ngenxa yokuba izinto ezintsha (i-calcium carbonate) zenziwe. ) nayo. Amalungu aphambili omgubo we-ash calcium zezi: umxube weCa(OH)2, iCaO kunye nesixa esincinci seCaCO3, CaO H2O=Ca(OH)2 —Ca(OH)2 CO2=CaCO3↓ H2O Indima ye-ash calcium kwi-CO2 emanzini kunye nomoya Ngaphantsi kwesi simo, i-calcium carbonate yenziwe, ngelixa i-HPMC igcina amanzi kuphela, incedisa ukusabela okungcono kwe-ash calcium, kwaye ayithathi nxaxheba kuyo nayiphi na impendulo ngokwayo.

2. Uthini ubungakanani be-HPMC eyongeziweyo kwi-putty powder?

——Impendulo: Isixa se-HPMC esisetyenzisiweyo kwizicelo eziphathekayo siyahluka ngokuxhomekeka kwimozulu, ukushisa, 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.

3. Yintoni i-viscosity efanelekileyo ye-HPMC kwi-putty powder?

——Impendulo: Ngokubanzi, i-yuan eyi-100,000 yanele kwiputty powder, kwaye iimfuno zodaka ziphezulu, kwaye i-yuan eyi-150,000 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 (i-70,000-80,000), nayo inokwenzeka. Ngokuqinisekileyo, ukuphakama kwe-viscosity, ngcono ukugcinwa kwamanzi okuhambelanayo. Xa i-viscosity idlula i-100,000, i-viscosity iya kuchaphazela ukugcinwa kwamanzi. Akusekho kakhulu.

4. Kutheni i-putty powder iphosa amagwebu?

——Impendulo: I-Phenomenon: amaqamza aveliswa ngexesha lenkqubo yokwakha kwaye emva kwexesha elithile, umphezulu we-putty uyagqabhuka.

unobangela:

1. Isiseko sirhabaxa kakhulu kwaye isantya sokutyabeka sikhawuleza kakhulu;

2. Umaleko we-putty kwisakhiwo esinye bukhulu kakhulu, mkhulu kune-2.0mm;

3. Ubumanzi bengca buphezulu kakhulu, kwaye ukuxinana kukhulu kakhulu okanye kuncinci kakhulu.

4. Emva kwexesha lokwakhiwa, ukuqhuma kunye ne-foaming phezu komhlaba kubangelwa ikakhulu ukuxuba okungalinganiyo, ngelixa i-HPMC idlala indima ekugcinweni kwamanzi, ukuqina kunye nokuphucula ukusebenza kwi-putty powder, kwaye ayithathi nxaxheba kuyo nayiphi na impendulo.

5. Sisiphi isizathu sokukhutshwa komgubo we-putty powder?

——Impendulo: Oku kunxulumene ikakhulu nobungakanani kunye nomgangatho wegrey calcium eyongeziweyo. Umxholo ophantsi we-calcium we-gray calcium kunye nomlinganiselo ongafanelekanga we-CaO kunye ne-Ca (OH) 2 kwi-gray calcium iya kubangela ukususwa kwe powder. Kwangaxeshanye, ikwanxulumene HPMC. Izinga lokugcinwa kwamanzi liphantsi, kwaye ixesha le-ash calcium hydration alanele, eliya kubangela nokususwa kwe powder.

6. Kutheni i-putty inzima kwinkqubo yokukhuhla?

——Impendulo: Kule meko, i-viscosity ye-cellulose esetyenziswa ngokubanzi iphezulu kakhulu. Abanye abavelisi basebenzisa i-200,000 yeselulosi ukwenza i-putty. I-putty eveliswe ngolu hlobo ine-viscosity ephezulu, ngoko ivakalelwa kakhulu xa ikhuhla. Isixa esicetyiswayo se-putty powder kwiindonga zangaphakathi yi-3-5 kg, kwaye i-viscosity yi-80,000-100,000.
