Ubungakanani be-HPMC obusetyenziswayo kwiindlela ezisebenzayo buyahluka ngokuxhomekeke kwimozulu, ubushushu, umgangatho womgubo we-calcium womlotha wasekuhlaleni, ifomula yomgubo we-putty kunye "nomgangatho ofunekayo kubathengi". Ngokubanzi, buphakathi kwe-4 kg kunye ne-5 kg. Umzekelo: uninzi lomgubo we-putty eBeijing yi-5 kg; uninzi lomgubo we-putty eGuizhou yi-5 kg ehlotyeni kunye ne-4.5 kg ebusika; ubungakanani be-putty eYunnan buncinci, ngokubanzi ukusuka kwi-3 kg ukuya kwi-4 kg, njl.njl.
Ingakanani i-viscosity efanelekileyo ye-hydroxypropyl methylcellulose (HPMC) ekuveliseni umgubo we-putty?
Umgubo wePutty ngokubanzi yi-100,000 yuan, kwaye iimfuno ze-mortar ziphezulu, kwaye i-150,000 yuan iyafuneka ukuze kube lula ukuyisebenzisa. Ngaphezu koko, owona msebenzi ubalulekileyo we-HPMC kukugcina amanzi, kulandele ukuqina. Kwi-putty powder, ukuba nje ukugcinwa kwamanzi kulungile kwaye i-viscosity iphantsi (70,000-80,000), kunokwenzeka. Kakade ke, xa i-viscosity iphezulu, kokukhona i-viscosity iphezulu, kokukhona i-viscosity ingaphezulu kwe-100,000, i-viscosity iya kuchaphazela ukugcinwa kwamanzi. Akusekho kakhulu.
Yintoni umsebenzi ophambili wokusetyenziswa kwe-HPMC kwi-putty powder?
Kwi-putty powder, i-HPMC idlala indima ezintathu zokwandisa ukuqina, ukugcina amanzi kunye nokwakha.
Ukuqina: I-Cellulose ingenziwa ibe nkulu ukuze ixhonywe kwaye igcine isisombululo sihambelana phezulu nasezantsi, kwaye singavumeli ukugoba.
Ukugcinwa kwamanzi: yenza umgubo we-putty wome kancinci, kwaye uncede i-ash calcium ukuba isabele phantsi kwentshukumo yamanzi.
Ulwakhiwo: I-Cellulose inefuthe lokuthambisa, nto leyo enokwenza ukuba umgubo we-putty ube nolwakhiwo oluhle.
I-HPMC ayithathi nxaxheba kuzo naziphi na ii-chemical reactions, kodwa idlala indima yokuncedisa kuphela. Ukongeza amanzi kwi-putty powder uze uyibeke eludongeni yi-chemical reaction, kuba izinto ezintsha ziyavela. Ukuba ususa i-putty powder eludongeni, uyigaye ibe yi-powder, uze uyisebenzise kwakhona, ayizukusebenza kuba izinto ezintsha (i-calcium carbonate) zenziwe. ) nazo. Izinto eziphambili ze-ash calcium powder zezi: umxube we-Ca(OH)2, i-CaO kunye ne-CaCO3 encinci, i-CaO H2O=Ca(OH)2—Ca(OH)2 CO2=CaCO3↓ H2O Indima ye-ash calcium kwi-CO2 emanzini nasemoyeni. Phantsi kwale meko, i-calcium carbonate iveliswa, ngelixa i-HPMC igcina amanzi kuphela, inceda i-ash calcium isebenze ngcono, kwaye ayithathi nxaxheba kuyo nayiphi na i-reaction ngokwayo.
