Xa sisebenzisa i-putty powder, kuya kuhlala kukho iingxaki, ngoko asazi isizathu.Ndicinga ukuba kufuneka kubekho iintlobo ezisixhenxe zeengxaki ezihlala zivela kwiputty powder!
Omnye: Yenza ngokukhawuleza.Oku kuhambelana ikakhulu nokongezwa kwe-calcium yothuthu kunye nesantya sokugcinwa kwamanzi kwifayibha, kwaye kunxulumene nokoma kodonga.
Zimbini: peel and roll.Oku kuhambelana nesantya sokugcinwa kwamanzi, okulula ukwenzeka xa i-viscosity ye-cellulose iphantsi okanye inani lokongezwa lincinci.
Ezintathu: ukususwa komgubo.Oku kuhambelana nomthamo we-ash calcium eyongeziweyo, kwaye inxulumene nomlinganiselo kunye nomgangatho we-cellulose eyongeziweyo.Kubonakaliswa kwizinga lokugcinwa kwamanzi kwimveliso.Izinga lokugcinwa kwamanzi liphantsi kwaye ixesha le-hydration ye-ash calcium ayanele.
Zine: Unamadyunguza.Oku kuhambelana nokufuma okomileyo kunye nokunyuka kodonga, kwaye kunxulumene nokwakhiwa.
Eyesihlanu: Kuvela inqaku lephini.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 obumbano ngexesha elinye.Ukongeza, le meko iyenzeka nakwiimveliso ezinje ngamaqela e-carboxyl afakwe kwiselulosi.
Isithandathu: Kuvela imiqolomba yentaba-mlilo kunye nemingxuma emincinci.Ngokucacileyo oku kunxulumene nokuxinana komphezulu wamanzi we-hydroxypropyl methylcellulose isisombululo se-aqueous, kodwa ukuxinezeleka komphezulu wamanzi wesisombululo esinamanzi se-hydroxyethyl akucaci.Kuya kuba ngcono ukwenza unyango olulula.
Esixhenxe: Emva kokuba i-putty yomile, kulula ukuqhekeka kwaye ijike ibe tyheli.Oku kuhambelana nokongezwa kwesixa esikhulu se-calcium engwevu.Ukuba ubuninzi be-calcium egrey bongezwa kakhulu, ubunzima be-putty powder buya kunyuka emva kokumisa.Ubunzima kuphela kwaye akukho bhetyebhetye kuya kuqhekeka ngokulula, ngakumbi xa iphantsi kwamandla angaphandle.Ikwanxulumene nomxholo ophezulu we-calcium oxide kwi-gray calcium.
1. Kutheni i-putty powder iba ncinane emva kokufaka amanzi?
I-ether ye-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 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.
2. Sisiphi isizathu sokuba i-putty inzima 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.
3. Kutheni i-putty kunye nomdaka owenziwe nge-cellulose kunye ne-viscosity efanayo uziva uhlukile ebusika nasehlotyeni?
Ngenxa ye-thermal gelation yemveliso, i-viscosity yemveliso 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 ukhethe imveliso ene-viscosity ephezulu xa usebenzisa imveliso ehlotyeni, okanye ukwandisa inani leselulosi, kwaye ukhethe imveliso enobushushu obuphezulu be-gel.
