Lapho senza futhi sifaka i-putty powder, sizohlangabezana nezinkinga ezihlukahlukene. Namuhla, esikhuluma ngakho ukuthi lapho i-putty powder ixubene namanzi, lapho ugoqa kakhulu, i-putty izoba mncane, futhi umcimbi wokuhlukaniswa kwamanzi uzoba mkhulu.
Imbangela yale nkinga ukuthi i-hydroxypropyl methylcellulose engezwe ku-putty powder ayifanelekile. Ake sibheke isimiso sokusebenza nokuthi singasixazulula kanjani.
Umgomo we-putty uba mncane futhi ube mncane:
1. I-viscosity ye-hydroxypropyl methylcellulose ayikhethwe ngendlela engafanele, i-viscosity iphansi kakhulu, futhi umphumela wokumisa awanele. Ngalesi sikhathi, ukuhlukaniswa kwamanzi okunzima kuzokwenzeka, futhi umphumela wokumisa umfaniswano ngeke ubonakale;
2. Engeza i-agent egcina amanzi ku-putty powder, enomphumela omuhle wokugcina amanzi. Lapho i-putty ichitheka ngamanzi, izokhiya inani elikhulu lamanzi. Ngalesi sikhathi, amanzi amaningi aqoqelwa ndawonye abe amaqoqo amanzi. Ngokunyakazisa amanzi amaningi ahlukaniswe, ngakho inkinga evamile ukuthi lapho ugoqa kakhulu, iba mncane. Abantu abaningi baye bahlangabezana nale nkinga, ungakwazi ukunciphisa kahle inani le-cellulose eyengeziwe noma unciphise amanzi angeziwe;
3. Iphinde ibe nobudlelwano obuthile nesakhiwo se-hydroxypropyl methylcellulose futhi ine-thixotropy. Ngakho-ke, ngemva kokwengeza i-cellulose, yonke ingubo ine-thixotropy ethile. Lapho i-putty inyakaziswa ngokushesha, isakhiwo sayo sonke sizohlakazeka futhi sibe mncane futhi sibe mncane, kodwa uma sishiywe singanyakazi, sizolulama kancane kancane.
Isixazululo: Uma usebenzisa i-putty powder, ngokuvamile wengeze amanzi futhi ugovuze ukuze afinyelele izinga elifanele, kodwa lapho ungeza amanzi, uzothola ukuthi amanzi amaningi engeziwe, aba mncane. Siyini isizathu salokhu?
1. I-Cellulose isetshenziswa njenge-thickener kanye ne-agent egcina amanzi ku-putty powder, kodwa ngenxa ye-thixotropy ye-cellulose ngokwayo, ukungezwa kwe-cellulose ku-putty powder nakho kuholela ku-thixotropy ngemva kokwengeza amanzi ku-putty;
2. Le thixotropy ibangelwa ukubhujiswa kwesakhiwo esihlangene ngokukhululekile sezingxenye ku-putty powder. Lesi sakhiwo sikhiqizwa ekuphumuleni futhi sihlakazwe ngaphansi kokucindezeleka, okungukuthi, i-viscosity iyancipha ngaphansi kokugqugquzela, futhi i-viscosity ekuphumuleni Ukubuyisela, ngakho-ke kuyoba khona into yokuthi i-putty powder iba mncane njengoba yengezwa ngamanzi;
3. Ngaphezu kwalokho, lapho i-putty powder isetshenziswa, yoma ngokushesha kakhulu ngoba ukwengezwa ngokweqile kwe-ash calcium powder kuhlobene nokomisa kodonga, futhi ukuxebuka nokuginqika kwe-putty powder kuhlobene nenani lokugcinwa kwamanzi. ;
4. Ngakho-ke, ukuze sigweme izimo ezingadingekile, kufanele sinake lezi zinkinga lapho sisisebenzisa.
Uma sisebenzisa i-putty powder, sihlala sihlangabezana nazo zonke izinhlobo zezinkinga eziyinqaba. Yebo, akunandaba. Uma nje sazi isimiso nekhambi, singakwazi ukuvimbela izinto ezinjalo ukuba zenzeke.
