1. Iingxaki eziqhelekileyo kumgubo we-putty
Ukomisa ngokukhawuleza: Oku kungenxa yobungakanani bomgubo we-calcium welayimu ongezelelweyo (ubukhulu kakhulu, ubungakanani bomgubo we-calcium welayimu osetyenzisiweyo kwifomula ye-putty bunokuncipha ngokufanelekileyo) bunxulumene nesantya sokugcina amanzi kwifayibha, kwaye bunxulumene nokoma kodonga.
Khuhla uze uqengqele. Oku kunxulumene nesantya sokugcina amanzi, okulula ukwenzeka xa i-viscosity ye-cellulose iphantsi okanye ubungakanani bokongeza buncinci.
Ukususwa komgubo we-putty yodonga lwangaphakathi: Oku kunxulumene nobungakanani bomgubo we-calcium womlotha ongezelelweyo (ubungakanani bomgubo we-calcium womlotha kwifomula ye-putty buncinci kakhulu okanye ubunyulu bomgubo we-calcium womlotha buphantsi kakhulu, kwaye ubungakanani bomgubo we-calcium womlotha kwifomula ye-putty powder kufuneka bonyuswe ngokufanelekileyo) Kwangaxeshanye, kunxulumene nobungakanani kunye nomgangatho we-cellulose, obonakala kwizinga lokugcina amanzi kwimveliso. Izinga lokugcina amanzi liphantsi, kwaye ixesha lomgubo we-calcium womlotha (i-calcium oxide kwi-ash calcium powder ayiguqulwanga ngokupheleleyo ibe yi-calcium hydroxide) alanele. ,kubangelwa.
Ukudumba: Oku kunxulumene nokufuma okomileyo kunye nokuba sicaba kodonga, kwaye kunxulumene nolwakhiwo.
Kuvela ii-Pinpoints. Oku kunxulumene ne-cellulose, eneempawu ezimbi zokwenza ifilimu. Kwangaxeshanye, ukungcola kwi-cellulose kusabela kancinci kwi-calcium yomlotha. Ukuba impendulo inzima, i-putty powder iya kubonakala kwimeko ye-bean curd residue. Ayinakubekwa eludongeni, kwaye ayinamandla adibeneyo ngaxeshanye. Ukongeza, le meko iyenzeka nakwiimveliso ezifana ne-carboxymethyl exutywe ne-cellulose.
Inkangeleko yee-craters kunye nee-pinholes: Oku ngokucacileyo kunxulumene noxinzelelo lwamanzi kwisisombululo samanzi se-hydroxypropyl methylcellulose. Uxinzelelo lwamanzi kwisisombululo samanzi se-hydroxyethyl alubonakali. Kuya kuba kuhle ukwenza unyango lokugqibela.
Emva kokuba i-putty yomile, kulula ukuyiqhekeza ize ibe tyheli: oku kunxulumene nokongezwa komgubo omkhulu we-calcium yomlotha. Ukuba ubungakanani bomgubo we-calcium yomlotha buninzi kakhulu, ubunzima bomgubo we-putty buya kwanda emva kokuba womile. Kuphela ubunzima obungenakuguquguquka obuya kuqhekeka lula, ngakumbi Kulula ukuyiqhekeza xa iphantsi kwamandla angaphandle. Ikwanxulumene nomxholo ophezulu we-calcium oxide kwi-ash calcium powder.
2. Kutheni i-putty powder iba ncinci emva kokufaka amanzi?
I-Cellulose isetyenziswa njengesithambisi kunye nearhente yokugcina 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 kukutshatyalaliswa kwesakhiwo esidibeneyo esidibeneyo sezinto ezikwi-putty powder. Esi sakhiwo sivela xa siphumle kwaye siqhekeka phantsi koxinzelelo. Oko kukuthi, i-viscosity iyancipha xa ixutywa, kwaye i-viscosity iyabuyela kwimeko yayo xa ime ngxi.
3. Yintoni isizathu sokuba i-putty ibe nzima xa kukhuhlwa?
Kule meko, i-viscosity ye-cellulose esetyenziswa ngokubanzi iphezulu kakhulu. Abanye abavelisi basebenzisa i-cellulose engama-200,000 ukwenza i-putty. I-putty eveliswa ngale ndlela ine-viscosity ephezulu, ngoko ke ivakala inzima xa ikrwelwa. Ubungakanani obucetyiswayo be-putty kwiindonga zangaphakathi yi-3-5 kg, kwaye i-viscosity yi-80,000-100,000.
4. Kutheni i-viscosity cellulose efanayo ivakala yahlukile ebusika nasehlotyeni?
Ngenxa yobushushu bemveliso, i-viscosity ye-putty kunye ne-mortar iya kuncipha kancinci kancinci xa ubushushu bunyuka. Xa ubushushu budlula ubushushu be-gel bemveliso, imveliso iya kuphuma emanzini ize ilahlekelwe yi-viscosity yayo. Ubushushu begumbi ehlotyeni buhlala bungaphezulu kwama-30 degrees, nto leyo eyahlukileyo kakhulu kubushushu basebusika, ngoko ke i-viscosity iphantsi. Kucetyiswa ukuba ukhethe imveliso ene-viscosity ephezulu xa ufaka imveliso ehlotyeni, okanye ukonyusa ubungakanani be-cellulose, kwaye ukhethe imveliso ene-gel ephezulu. Zama ukungasebenzisi i-methyl cellulose ehlotyeni. Ubushushu be-gel buphakathi kwama-55 degrees, ubushushu buphezulu kancinci, kwaye i-viscosity yayo iya kuchaphazeleka kakhulu.
