Malunga ne-hydroxypropyl methylcellulose ngexesha lokusetyenziswa kwe-putty powder

1. Iingxaki eziqhelekileyo kwi-putty powder

[Ukomisa ngokukhawuleza] Oku kunxulumene ikakhulu nomthamo we-ash calcium powder eyongeziweyo (inkulu kakhulu, inokunciphisa ngokufanelekileyo umthamo we-ash calcium powder esetyenziswe kwi-putty formula) kunye nesantya sokugcinwa kwamanzi kwe-hydroxypropyl methylcellulose (HPMC), kwaye nayo inxulumene Inxulumene nokoma kodonga.

[Ulusu kunye nokugoba] Oku kuhambelana nezinga lokugcinwa kwamanzi. I-Hydroxypropyl methylcellulose (HPMC) ine-viscosity ephantsi kwaye ixhomekeke kule meko okanye inani lokongezwa lincinci.

[Ukususwa komgubo we-putty yodonga lwangaphakathi] Oku kuhambelana nomthamo we-ash calcium powder eyongeziweyo (ubuninzi be-ash calcium powder kwi-putty formula incinci kakhulu okanye ukucoceka kwe-ash calcium powder kuphantsi kakhulu, kunye nomthamo wothuthu. I-calcium powder kwi-putty powder formula kufuneka inyuswe ngokufanelekileyo) Ngexesha elifanayo, likwahambelana nomlinganiselo kunye nomgangatho we-hydroxypropyl methylcellulose (HPMC), ebonakaliswa kwinqanaba lokugcinwa kwamanzi kwimveliso. Izinga lokugcinwa kwamanzi liphantsi, kwaye i-calcium oxide kwi-ash calcium powder ayifaki ngokupheleleyo i-Calcium hydroxide conversion hydration) ixesha alanelanga, libangelwa.

[Ukugqabhuka] Oku kunxulumene nokufuma okomileyo kunye nokuba mcaba kodonga, kwaye kukwanxulumene nolwakhiwo.

[Amanqaku avelayo] Oku kunxulumene neselulosi, eneempawu ezimbi zokwenza ifilimu, kunye nobumdaka obukwi-hydroxypropyl methylcellulose (HPMC) busabela kancinane ngekhalsiyam yothuthu. Ukuba impendulo inzima, i-putty powder iya kubonakala i-tofu Slag state. Ayinakubekwa eludongeni, kwaye ayinayo amandla adibeneyo ngexesha elinye. Ukongeza, iimveliso ezifana ne-hydroxypropyl methylcellulose (HPMC) exutywe neqela le-carboxymethyl nazo ziyavela kule meko.

[Imiqolomba yentaba-mlilo kunye neepinhole ziyavela] 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.

[I-putty kulula ukuqhekeka kwaye ijike ibe tyheli emva kokoma] Oku kunxulumene nokongezwa komgubo omkhulu wekhalsiyam yothuthu. Ukuba inani le-ash calcium powder lifakwe kakhulu, ubunzima be-putty powder buya kwanda emva kokumisa. Ukuqina kuphela ngaphandle kokuguquguquka kuya kuqhekeka ngokulula, ngakumbi Kunokwenzeka ukuba uqhekeke xa uphantsi 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.
