1. Iingxaki eziqhelekileyo kwi-putty powder
Yoma ngokukhawuleza.Oku ikakhulu ngenxa yokuba isixa somgubo wekhalsiyam eyongeziweyo (inkulu kakhulu, isixa somgubo wekhalsiyam esetyenziswa kwifomula yeputty sinokuncitshiswa ngokufanelekileyo) sinxulumene nesantya sokugcinwa kwamanzi kwifayibha, kwaye ikwanxulumene nokoma. yodonga.
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 (umthamo we-ash calcium powder kwi-putty formula incinci kakhulu okanye ukucoceka kwe-ash calcium powder kuphantsi kakhulu, kunye nomthamo we-ash calcium powder kwi-putty powder formula kufuneka. yandiswe ngokufanelekileyo), kwaye ikwanxulumene nokongezwa kweselulosi.Kukho ubudlelwane phakathi kobuninzi kunye nomgangatho, 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) ixesha alanele, elibangelwa.
bubbly.Oku kuhambelana nokufuma okomileyo kunye nokunyuka kodonga, kwaye kunxulumene nokwakhiwa.
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 elifanayo.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 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 kokuba amanzi afakwe 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.
