1. Iingxaki eziqhelekileyo kwi-putty powder
yome ngokukhawuleza
Oku kuhambelana kakhulu nomthamo we-ash calcium powder eyongeziweyo (inkulu kakhulu, ubuninzi be-ash calcium powder esetyenziswe kwi-putty formula inokuncitshiswa ngokufanelekileyo) kunye nesantya sokugcinwa kwamanzi kwe-hydroxypropyl methylcellulose (HPMC), kwaye inxulumene nayo. ukoma kodonga ezinxulumene.
Ukuxobula kunye nokuqengqeleka
Oku kuhambelana nezinga lokugcinwa kwamanzi, okulula ukwenzeka xa i-viscosity ye-hydroxypropyl methylcellulose (HPMC) iphantsi okanye inani elongezelelweyo lincinci.
I-De-powdering yodonga lwangaphakathi lwe-putty powder
Oku kuhambelana nomthamo we-ash calcium powder (ubungakanani be-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 ube inyuswe ngokufanelekileyo), kwaye inxulumene nobungakanani be-hydroxypropyl methyl Isixa sesiseko se-cellulose (HPMC) sinxulumene nomgangatho, obonakaliswa kwizinga 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.,ibangelwa.
ukugquma
Oku kuhambelana nokufuma okomileyo kunye nokunyuka kodonga, kwaye kunxulumene nokwakhiwa.
pin point
Oku kuhambelana ne-cellulose, eneempawu ezimbi zokwenza ifilimu.Ngaxeshanye, ukungcola kwi-hydroxypropyl methylcellulose (HPMC) kusabela kancinane nge-ash calcium.Ukuba ukusabela kubukhali, i-putty powder iya kuba kwimeko yentsalela yebhontshisi.Ayinakubekwa eludongeni, kwaye ayinayo amandla adibeneyo ngexesha elinye.Ukongeza, iimveliso ezifana ne-hydroxypropyl methylcellulose (HPMC) exutywe neqela le-carboxymethyl nazo ziyavela kule meko.
Kuvela iintaba-mlilo kunye nemingxuma
Oku ngokucacileyo kunxulumene noxinzelelo lomphezulu wamanzi we-hydroxypropyl methylcellulose (HPMC) 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?
IHydroxypropyl methylcellulose (HPMC) isetyenziswa njengento etyebisayo kunye ne-agent egcina amanzi kwi-greasy.Ngenxa ye-thixotropy ye-hydroxypropyl methylcellulose (HPMC), i-hydroxypropyl methylcellulose kwi-putty powder Ukongezwa kwe-HPMC kubangele i-thixotropy emva kokufaka 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-hydroxypropyl methylcellulose (HPMC) esetyenziswa ngokubanzi iphezulu kakhulu, kwaye abanye abavelisi basebenzisa i-yuan engama-200,000 ukwenza i-putty.I-putty eveliswe ngolu hlobo ine-viscosity ephezulu, ngoko iya kutshona xa i-batch ikhuhla.imvakalelo ye.Isixa esicetyiswayo se-putty kwiindonga zangaphakathi yi-3-5 kg, kwaye i-viscosity yi-80,000-100,000.
4. Kutheni uvakalelwa kukuba i-viscosity ye-hydroxypropyl methylcellulose (HPMC) ene-viscosity efanayo iyahluka 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-hydroxypropyl methylcellulose (HPMC), kwaye ukhethe imveliso enobushushu obuphezulu be-gel.
