1. Iingxaki eziqhelekileyo kwi-putty powder
Ukomisa ngokukhawuleza kubangelwa ubukhulu becala lomgubo we-ash calcium eyongeziweyo (inkulu kakhulu, isixa se-ash calcium powder esetyenziswe kwi-putty formula sinokuncitshiswa ngokufanelekileyo) inxulumene nesantya sokugcinwa kwamanzi kwifayibha, kwaye inxulumene kwakhona. ukoma kodonga.
I-peeling kunye ne-curling ihambelana nesantya sokugcinwa kwamanzi, okulula ukuba kwenzeke xa i-viscosity ye-cellulose iphantsi okanye inani lokongezwa lincinci.
Ukususwa komgubo wodonga lwangaphakathi lwe-putty powder 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 nobungakanani kunye nomgangatho we-cellulose, obonakaliswa kwinqanaba 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.bangelwa.
I-Foaming inxulumene nokufuma okomileyo kunye nokunyuka kodonga, kwaye kunxulumene nokwakhiwa.
Ukubonakala kwee-pinpoints kuhambelana ne-cellulose, eneempawu ezimbi zokwenza ifilimu.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 elinye.Ukongeza, le meko iyenzeka nakwiimveliso ezifana ne-carboxymethyl exutywe neselulosi.
Iicraters kunye nemingxuma yokuqhafaza ziyavela.Ngokucacileyo oku kunxulumene nokuxinana komphezulu wamanzi we-hydroxypropyl methylcellulose isisombululo samanzi.Uxinzelelo lwetafile yamanzi kwisisombululo samanzi se-hydroxyethyl ayicacanga.Kuya kulunga ukwenza unyango lokugqiba.
Emva kokuba iputty yomile, kulula ukuqhekeka kwaye ijike ibe tyheli.Oku kuhambelana nokongezwa komthamo omkhulu we-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, iya kuqhekeka ngokulula, 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 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-Around 55 degrees, ukuba iqondo lokushisa liphezulu kancinci, i-viscosity yayo iya kuchaphazeleka kakhulu.
