1. Iingxaki eziqhelekileyo kwi-putty powder
Yoma ngokukhawuleza:
Isizathu esona sizathu kukuba isixa se-ash calcium powder esongeziweyo (inkulu kakhulu, isixa se-ash calcium powder esisetyenziswe kwi-putty formula sinokuncitshiswa ngokufanelekileyo) sinxulumene nesantya sokugcinwa kwamanzi kwefiber, kwaye inxulumene nokoma kodonga.
Ukuxobula kunye nokuqengqeleka:
Ihambelana nezinga lokugcinwa kwamanzi, kwaye i-viscosity ephantsi ye-cellulose ixhomekeke kule meko okanye inani lokongezwa lincinci.
Ukukhutshwa komgubo wangaphakathi wodonga lweputty:
Umthamo wepowder ye-ash calcium eyongeziweyo (umthamo we-ash calcium powder kwi-putty formula incinci kakhulu okanye ukucoceka komgubo we-ash calcium uphantsi kakhulu, kunye nomthamo we-ash calcium powder kwi-putty powder formula kufuneka yandiswe ngokufanelekileyo), kwaye inxulumene nesixa seselulosi kunye nomgangatho unxulumene, obonakaliswa kwizinga lokugcinwa kwamanzi kwimveliso. Izinga lokugcinwa kwamanzi liphantsi, kwaye i-ash calcium powder (i-calcium oxide kwi-ash calcium powder ayiguqulwanga ngokupheleleyo kwi-calcium hydroxide ye-hydration) ayikho ixesha elaneleyo, elibangelwayo.
Ugwebu:
Ukufuma okomileyo eludongeni kuhambelana nokucaba, kwaye kunxulumene nokwakhiwa.
Ingongoma ibonakala:
Inxulumene ne-cellulose, ipropati yayo yokwenza ifilimu ihlwempuzekileyo, kwaye ngexesha elifanayo, 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 elifanayo. Ukongeza, le meko iyenzeka nakwiimveliso ezifana ne-carboxymethyl exutywe neselulosi.
Emva kokuba iputty yomile, kulula ukuqhekeka kwaye ijike ibe tyheli:
Inxulumene nokongezwa kwenani elikhulu le-ash-calcium powder. Ukuba inani le-ash-calcium powder liyongezwa kakhulu, ubunzima be-putty powder buya kwanda emva kokumisa. Ukuba i-putty powder ayinakho ukuguquguquka, kuya kuba lula ukuqhekeza, ngakumbi xa iphantsi 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 isetyenziswa 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 esibophekileyo se-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. Kucetyiswa ukuba ehlobo, zama ukukhetha imveliso ene-viscosity ephezulu xa usebenzisa imveliso, okanye ukwandisa inani le-cellulose.
