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 iiyuan ezingama-150,000 ziyafuneka ukuze zisetyenziswe 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.
Ukujiya: 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.
