1. Iingxaki eziqhelekileyo kwi-putty powder
Ukomisa ngokukhawuleza: Oku kubangelwa ikakhulu kumthamo wekalika ye-lime powder eyongeziweyo (inkulu kakhulu, isixa se-lime calcium powder esetyenziswa kwi-putty formula ingancitshiswa ngokufanelekileyo) inxulumene nesantya sokugcinwa kwamanzi kwifayibha, kwaye ikwanjalo. enxulumene nokoma kodonga.
Peel kwaye uqengqe.Oku kuhambelana nesantya sokugcinwa kwamanzi, okulula ukwenzeka xa i-viscosity ye-cellulose iphantsi okanye inani lokongezwa lincinci.
I-De-powdering yodonga lwangaphakathi lwe-putty powder: Oku kuhambelana nomthamo we-ash calcium powder eyongeziweyo (ubuninzi be-ash calcium powder kwi-putty formula incinci kakhulu okanye ukucoceka kwe-ash calcium powder kuphantsi kakhulu, kunye nomthamo wothuthu. I-calcium powder kwi-putty powder formula kufuneka inyuswe ngokufanelekileyo) Ngexesha elifanayo, likwanxulumene nomlinganiselo kunye nomgangatho we-cellulose, obonakaliswa kwizinga lokugcinwa kwamanzi kwimveliso.Izinga lokugcinwa kwamanzi liphantsi, kwaye ixesha le-ash calcium powder (i-calcium oxide kwi-ash calcium powder ayiguqulwanga ngokupheleleyo kwi-calcium hydroxide) ayanele.,ibangelwa.
Amadyungudyungu: Oku kunxulumene nokufuma okomileyo kunye nokuthe tyaba eludongeni, kwaye kukwanxulumene nolwakhiwo.
Amanqaku ayavela.Oku kuhambelana ne-cellulose, eneempawu ezimbi zokwenza ifilimu.Ngelo xesha, ukungcola kwi-cellulose kusabela kancinci nge-ash calcium.Ukuba ukusabela kubukhali, i-putty powder iya kubonakala kwimeko yentsalela yebhontshisi.Ayinakubekwa eludongeni, kwaye ayinayo amandla adibeneyo ngexesha elinye.Ukongeza, le meko iyenzeka nakwiimveliso ezifana ne-carboxymethyl exutywe neselulosi.
Inkangeleko yecraters kunye neepinholes: Oku ngokucacileyo kunxulumene noxinzelelo lomphezulu wamanzi we-hydroxypropyl methylcellulose isisombululo samanzi.Uxinzelelo lwetafile yamanzi kwisisombululo samanzi se-hydroxyethyl ayicacanga.Kuya kulunga ukwenza unyango lokugqiba.
Emva kokuba i-putty isomile, kulula ukukrazula kunye nokujika kwephuzi: oku kuhambelana nokongezwa kwenani elikhulu le-ash calcium powder.Ukuba inani le-ash calcium powder lininzi kakhulu, ubunzima be-putty powder buya kunyuka emva kokumisa.Ukuqina kuphela ngaphandle kokuguquguquka kuya kuqhekeka ngokulula, ngakumbi Kulula ukuqhekeka xa uphantsi kwamandla angaphandle.Kwakhona kuhambelana nomxholo ophezulu we-calcium oxide kwi-ash calcium powder.
2. Kutheni le nto i-putty powder iba ncinane emva kokufaka amanzi?
I-cellulose isetyenziswe njenge-thickener kunye ne-agent egcina amanzi kwi-putty.Ngenxa ye-thixotropy ye-cellulose ngokwayo, ukongezwa kwe-cellulose kwi-putty powder kukhokelela kwi-thixotropy emva kokongeza amanzi kwi-putty.Le thixotropy ibangelwa ukutshatyalaliswa kwesakhiwo esidibeneyo samacandelo kwi-putty powder.Esi sakhiwo sivela ekuphumleni kwaye siphule phantsi koxinzelelo.Oko kukuthi, i-viscosity iyancipha phantsi kokuvuselela, kwaye i-viscosity iphinda ibuyele xa imile.
3. Sisiphi isizathu sokuba i-putty ibe nzima kakhulu kwinkqubo yokukhuhla?
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 kwiindonga zangaphakathi yi-3-5 kg, kwaye i-viscosity yi-80,000-100,000.
4. Kutheni i-cellulose ye-viscosity efanayo ivakalelwa ngokwahlukileyo ebusika nasehlotyeni?
Ngenxa ye-thermal gelation yemveliso, i-viscosity ye-putty kunye nomdaka iya kuncipha ngokuthe ngcembe ngokunyuka kweqondo lokushisa.Xa iqondo lokushisa lidlula ukushisa kwe-gel yemveliso, imveliso iya kuhlanjululwa emanzini kwaye ilahlekelwe yi-viscosity yayo.Ukushisa kwegumbi ehlotyeni ngokuqhelekileyo kungaphezulu kwama-30 degrees, okuhluke kakhulu kwiqondo lokushisa ebusika, ngoko i-viscosity iphantsi.Kunconywa ukuba ukhethe imveliso ene-viscosity ephezulu xa usebenzisa imveliso ehlobo, okanye ukwandisa inani le-cellulose, kwaye ukhethe imveliso enobushushu obuphezulu be-gel.Zama ukungasebenzisi i-methyl cellulose ehlotyeni.Ubushushu bejeli buphakathi kwe-55 degrees, iqondo lobushushu liphezulu kancinci, kwaye i-viscosity yayo iya kuchaphazeleka kakhulu.
