ukoma ngokukhawuleza
Oku kungenxa yokongezwa kakhulu komgubo we-ash calcium (ubungakanani bomgubo we-ash calcium osetyenziswa kwifomula ye-putty bunokunciphisa ngokufanelekileyo) oku kunxulumene nesantya sokugcina amanzi se-hydroxypropyl methylcellulose, kwaye kunxulumene nokoma kodonga.
Ukuxobula nokuqengqeleka
Oku kunxulumene nomxholo ophezulu we-ash calcium okanye izinga eliphantsi lokugcinwa kwamanzi le-hydroxypropyl methylcellulose, elikwanokwenzeka xa i-viscosity ye-cellulose iphantsi okanye inani elongeziweyo lincinci.
Ukususa umgubo 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), kwaye kunxulumene nokongezwa kwe-cellulose Kukho ubudlelwane phakathi kobuninzi kunye nomgangatho, obonakala kwizinga lokugcina amanzi kwimveliso. Izinga lokugcina amanzi liphantsi, kwaye ixesha lokuphendula lomgubo we-calcium womlotha (i-calcium oxide kwi-calcium powder yomlotha ayiguqulwanga ngokupheleleyo ibe yi-calcium hydroxide) alwanele, nto leyo ebangelwa.
ukubila
Oku kunxulumene nokufuma okomileyo kunye nokuba tyaba kodonga, kwaye kunxulumene nolwakhiwo.
indawo yephini
Oku kunxulumene ne-cellulose, eneempawu ezimbi zokwenza ifilimu. Kwangaxeshanye, ukungcola kwi-cellulose kusabela kancinci kwi-calcium yomlotha. Ukuba impendulo inzima, umgubo we-putty uya kubonakala kwimeko ye-bean curd residue. Ayinakubekwa eludongeni, kwaye ayinamandla adibeneyo ngaxeshanye. Ukongeza, le meko iyenzeka nakwiimveliso ezifana ne-carboxymethyl exutywe ne-cellulose.
Kuvela iintaba-mlilo kunye nemingxuma yemigodi
Oku ngokucacileyo kunxulumene noxinzelelo lwamanzi kwisisombululo samanzi se-hydroxypropyl methylcellulose. Uxinzelelo lwamanzi kwisisombululo samanzi se-hydroxyethyl alubonakali. Kuya kuba kuhle ukwenza unyango lokugqibela. Kukwanxulumene nokongeza kakhulu i-hydroxypropyl methylcellulose.
Emva kokuba i-putty yomile, kulula ukuyiqhekeza ize ijike ibe tyheli
Oku kunxulumene nokongezwa komgubo omkhulu we-ash-calcium. Ukuba umgubo we-ash-calcium wongezwa kakhulu, ubunzima bomgubo we-putty buya kwanda emva kokuba womile. Ukuba umgubo we-putty awunakuguquguquka, uya kuqhekeka lula, ingakumbi xa uphantsi kwamandla angaphandle. Kukwanxulumene nomxholo ophezulu we-calcium oxide kwi-ash calcium powder.
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.
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.
Kutheni i-viscosity ye-cellulose ivakala yahlukile xa kusetyenziswa i-viscosity cellulose efanayo ebusika nasehlotyeni?
Ngenxa yokufudumala kwemveliso, 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 kwaye ilahlekelwe yi-viscosity yayo. Ubushushu begumbi ehlotyeni ngokubanzi 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 ukwandisa ubungakanani be-cellulose, kwaye ukhethe imveliso ene-viscosity ephezulu ye-gel.
