Xa senza kwaye sisebenzisa umgubo we-putty, siza kudibana neengxaki ezahlukeneyo. Namhlanje, esikuthethayo kukuba xa umgubo we-putty uxutywe namanzi, okukhona uxuba, kokukhona i-putty iya kuba ncinci, kwaye imeko yokwahlulwa kwamanzi iya kuba yingozi.
Unobangela oyintloko wale ngxaki kukuba i-hydroxypropyl methylcellulose eyongezwe kwi-putty powder ayifanelekanga. Makhe sijonge umgaqo osebenzayo kunye nendlela esinokuyisombulula ngayo.
Umgaqo wokuba umgubo we-putty ube mncinci ngakumbi nangakumbi:
1. I-viscosity ye-hydroxypropyl methylcellulose ayikhethwanga kakuhle, i-viscosity iphantsi kakhulu, kwaye isiphumo sokuxhoma asanele. Ngeli xesha, kuya kwenzeka ukwahlukana okukhulu kwamanzi, kwaye isiphumo sokuxhoma esifanayo asiyi kubonakaliswa;
2. Yongeza into yokugcina amanzi kwi-putty powder, enefuthe elihle lokugcina amanzi. Xa i-putty inyibilika ngamanzi, iya kutshixa amanzi amaninzi. Ngeli xesha, amanzi amaninzi axutywa abe ngamaqela amanzi. Ngokuxutywa kwamanzi amaninzi ayahlukana, ngoko ke ingxaki eqhelekileyo kukuba okukhona uxuba, kokukhona iba ncinci. Abantu abaninzi baye badibana nale ngxaki, unganciphisa ngokufanelekileyo inani le-cellulose eyongeziweyo okanye unciphise amanzi ongezelelweyo;
3. Inobudlelwane obuthile nesakhiwo se-hydroxypropyl methylcellulose kwaye ine-thixotropy. Ke ngoko, emva kokongeza i-cellulose, yonke i-coating ine-thixotropy ethile. Xa i-putty ixutywa ngokukhawuleza, isakhiwo sayo siphela siya kusasazeka size sibe mncinci kwaye sinciphe, kodwa xa ishiywe inganyakazi, iya kubuyela esiqhelweni kancinci.
Isisombululo: Xa usebenzisa i-putty powder, ngokuqhelekileyo yongeza amanzi uze uxube ukuze ifikelele kwinqanaba elifanelekileyo, kodwa xa wongeza amanzi, uya kufumanisa ukuba amanzi amaninzi ongezwayo, kokukhona encipha. Yintoni isizathu soku?
1. I-Cellulose isetyenziswa njengesithambisi kunye nearhente yokugcina amanzi kwi-putty powder, kodwa ngenxa ye-thixotropy ye-cellulose ngokwayo, ukongezwa kwe-cellulose kwi-putty powder kukhokelela kwi-thixotropy emva kokongeza amanzi kwi-putty;
2. Le thixotropy ibangelwa kukutshatyalaliswa kwesakhiwo esidibeneyo esidibeneyo sezinto ezikwi-putty powder. Esi sakhiwo siveliswa xa siphumle size siqhekeke phantsi koxinzelelo, oko kukuthi, i-viscosity iyancipha xa ixutywa, kwaye i-viscosity xa iphumle Ukubuyisela, ngoko ke kuya kubakho isiganeko sokuba i-putty powder iba ncinci njengoko yongezwa ngamanzi;
3. Ukongeza, xa kusetyenziswa umgubo we-putty, woma ngokukhawuleza kakhulu kuba ukongezwa kakhulu komgubo we-calcium womlotha kunxulumene nokoma kodonga. Ukuxobuka nokuqengqeleka komgubo we-putty kunxulumene nesantya sokugcina amanzi;
4. Ke ngoko, ukuze siphephe iimeko ezingeyomfuneko, kufuneka siqwalasele ezi ngxaki xa siyisebenzisa.
