yome ngokukhawuleza
Oku ikakhulu ngenxa yokongezwa okugqithisileyo kwe-ash calcium powder (isixa se-ash calcium powder esisetyenziswe kwi-putty formula sinokuncitshiswa ngokufanelekileyo) sinxulumene nesantya sokugcinwa kwamanzi e-hydroxypropyl methylcellulose, kwaye inxulumene nokomisa kodonga. .
Ukuxobula kunye nokuqengqeleka
Oku kuhambelana nomxholo ophezulu we-ash calcium okanye izinga lokugcinwa kwamanzi aphantsi kwe-hydroxypropyl methylcellulose, enokuthi yenzeke xa i-viscosity ye-cellulose iphantsi okanye inani elongezelelweyo 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. kwandiswe ngokufanelekileyo), kwaye inxulumene nokongezwa kwe-cellulose Kukho ubudlelwane phakathi kobuninzi kunye nomgangatho, obonakaliswa kwizinga lokugcinwa kwamanzi kwimveliso.Izinga lokugcinwa kwamanzi liphantsi, kwaye ixesha lokuphendula i-ash calcium powder (i-calcium oxide kwi-ash calcium powder ayiguqulwanga ngokupheleleyo kwi-calcium hydroxide) ayanelanga, ebangelwa.
ukugquma
Oku kuhambelana nokufuma okomileyo kunye nokunyuka kodonga, kwaye kunxulumene nokwakhiwa.
pin point
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.
Kuvela iintaba-mlilo kunye nemingxuma
Ngokucacileyo oku kunxulumene nokuxinana komphezulu wamanzi we-hydroxypropyl methylcellulose isisombululo samanzi.Uxinzelelo lwetafile yamanzi kwisisombululo samanzi se-hydroxyethyl ayicacanga.Kuya kulunga ukwenza unyango lokugqiba.Ikwanxulumene nokongezwa okugqithisileyo kwe-hydroxypropyl methylcellulose.
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.
Kutheni le nto i-putty powder iba yincinci emva kokongeza 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 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.
Sesiphi isizathu sokuba i-putty inzima kakhulu kwinkqubo yokukrazula?
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.
Kutheni i-viscosity ye-cellulose ivakalelwa ngokwahlukileyo xa usebenzisa i-viscosity cellulose efanayo 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.
