Ulwazi lwesicelo se-hydroxypropyl methylcellulose kwi-putty powder

Isixa se-HPMC esisetyenzisiweyo kwizicelo ezisebenzayo siyahluka ngokuxhomekeka kwimozulu, ubushushu, umgangatho wepowder ash calcium yendawo, ifomula ye-putty powder kunye "nomgangatho ofunwa ngabathengi". Ngokuqhelekileyo, iphakathi 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.

Yiyiphi i-viscosity efanelekileyo ye-hydroxypropyl methylcellulose (HPMC) yokuvelisa i-putty powder?

I-Putty powder iqhele ukuba yi-yuan eyi-100,000, 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.

Nguwuphi umsebenzi oyintloko wokusetyenziswa kwe-HPMC kwi-putty powder?

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. Amacandelo aphambili e-ash calcium powder ngala: umxube weCa(OH)2, iCaO kunye nomlinganiselo omncinci weCaCO3, 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.
