Iingxaki eziqhelekileyo ze-putty ezinganyangekiyo ngamanzi kwiindonga zangaphakathi

1. Iingxaki eziqhelekileyo kwiputty powder:

1.1 Yoma ngokukhawuleza.Oku kuhambelana ikakhulu nokongezwa kwe-calcium yothuthu kunye nesantya sokugcinwa kwamanzi kwifayibha, kwaye kunxulumene nokoma kodonga.

1.2 Ukuxobula nokuqengqeleka.Oku kuhambelana nesantya sokugcinwa kwamanzi, okulula ukwenzeka xa i-viscosity ye-cellulose iphantsi okanye inani lokongezwa lincinci.

1.3 Ukuphelisa umgubo.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.

1.4 Ukugqabhuka kwamadyungudyungu.Oku kuhambelana nokufuma okomileyo kunye nokunyuka kodonga, kwaye kunxulumene nokwakhiwa.

1.5 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.

1.6 Kuvela iintaba-mlilo kunye nemingxuma emincinane.Ngokucacileyo oku kunxulumene nokuxinana komphezulu wamanzi we-hydroxypropyl methylcellulose isisombululo samanzi.Uxinzelelo lwetafile yamanzi kwisisombululo samanzi se-hydroxyethyl ayicacanga.Kuya kulunga ukwenza unyango lokugqiba.

1.7 Emva kokuba iputty 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, eyaziswa ngaphambili.

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. Kutheni iputty inzima 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-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.Kunconywa ukuba ukhethe imveliso ene-viscosity ephezulu ehlobo, okanye ukwandisa inani le-cellulose, kwaye ukhethe imveliso enobushushu obuphezulu be-gel.Zama ukukhetha imveliso kunye nobushushu be-gel ngaphezu kwama-70 degrees.Zama ukuba ungasebenzisi i-methyl cellulose ehlotyeni, ubushushu bayo be-gel bujikeleze ama-degrees angama-55, ukuba ubushushu buphezulu kancinci, i-viscosity yayo iya kuchaphazeleka kakhulu.
