Uma sisebenzisa i-putty powder, kuvame ukuba nezinkinga ezithile, ngakho-ke asazi isizathu. Ngicabanga ukuthi kufanele kube nezinhlobo eziyisikhombisa zezinkinga ezivame ukuvela ku-putty powder!
Okokuqala: Kwenze ngokushesha. Lokhu kuhlobene kakhulu nokwengezwa kwe-calcium yomlotha kanye nezinga lokugcina amanzi kwefayibha, futhi kuhlobene nokoma kodonga.
Okwesibili: ukuhlubula bese ugoqa. Lokhu kuhlobene nesilinganiso sokugcina amanzi, okulula ukwenzeka uma i-viscosity ye-cellulose iphansi noma inani lokwengeza lincane.
Okwesithathu: ukususwa kwempuphu. Lokhu kuhlobene nenani le-calcium yomlotha engeziwe, futhi kuhlobene nenani kanye nekhwalithi ye-cellulose engeziwe. Kubonakala ngesilinganiso sokugcina amanzi somkhiqizo. Izinga lokugcina amanzi liphansi futhi isikhathi sokumanzisa kwe-calcium yomlotha asanele.
Okwesine: Ukuqhumisa. Lokhu kuhlobene nomswakama owomile kanye nokuba yisicaba kodonga, futhi kuhlobene nokwakhiwa kwalo.
Isihlanu: Kuvela iphuzu lephini. Lokhu kuhlobene ne-cellulose, enezakhiwo ezimbi zokwakha ifilimu. Ngesikhathi esifanayo, ukungcola ku-cellulose kusabela kancane ne-calcium yomlotha. Uma ukusabela kukubi kakhulu, i-putty powder izovela esimweni se-residue ye-bean curd. Ayikwazi ukufakwa odongeni, futhi ayinawo amandla okuhlangana ngesikhathi esifanayo. Ngaphezu kwalokho, lesi simo siyenzeka nangemikhiqizo efana namaqembu e-carboxyl engezwe ku-cellulose.
Isithupha: Kuvela imihume yentaba-mlilo kanye nemigodi emincane. Lokhu kusobala ukuthi kuhlobene nokucindezeleka kwamanzi kwesisombululo samanzi se-hydroxypropyl methylcellulose, kodwa ukucindezeleka kwamanzi kwesisombululo samanzi se-hydroxyethyl akubonakali. Kuzoba ngcono ukwenza ukwelashwa okulula.
Isikhombisa: Ngemva kokuba i-putty yomile, kulula ukuyiqhekeka bese iphenduka ibe phuzi. Lokhu kuhlobene nokwengezwa kwenani elikhulu le-calcium empunga. Uma inani le-calcium empunga lingezwa kakhulu, ubulukhuni bempuphu ye-putty buzokhula ngemva kokoma. Ubulukhuni kanye nokungabi nokuguquguquka kuphela okuzoqhekeka kalula, ikakhulukazi uma kungaphansi kwamandla angaphandle. Kuhlobene futhi nokuqukethwe okuphezulu kwe-calcium oxide ku-calcium empunga.
1. Kungani i-putty powder iba ncane ngemva kokufaka amanzi?
I-cellulose ether isetshenziswa njengesithambisi kanye nesithambisi sokugcina amanzi ku-putty. Ngenxa ye-thixotropy ye-cellulose uqobo, ukungezwa kwe-cellulose ku-putty powder nakho kuholela ku-thixotropy ngemva kokufaka amanzi ku-putty. Le thixotropy ibangelwa ukubhujiswa kwesakhiwo esihlanganisiwe kalula sezingxenye ku-putty powder. Lesi sakhiwo sivela lapho siphumule futhi siwohloka ngaphansi kokucindezeleka. Okusho ukuthi, i-viscosity iyancipha lapho ixutshwa, futhi i-viscosity iyalulama lapho ime ndawonye.
2. Yisiphi isizathu esenza i-putty ibe nzima kakhulu enqubweni yokuklwebha?
Kulesi simo, i-viscosity ye-cellulose esetshenziswa ngokuvamile iphakeme kakhulu. Abanye abakhiqizi basebenzisa i-cellulose engu-200,000 ukwenza i-putty. I-putty ekhiqizwa ngale ndlela inobuthi obukhulu, ngakho-ke izwakala inzima uma iklwejwa. Inani elinconywayo le-putty yezindonga zangaphakathi lingu-3-5 kg, kanti i-viscosity ingu-80,000-100,000.
3. Kungani i-putty kanye nodaka okwenziwe nge-cellulose ene-viscosity efanayo kuzwakala kuhlukile ebusika nasehlobo?
Ngenxa yokushisa komkhiqizo, i-viscosity yomkhiqizo izoncipha kancane kancane ngokukhuphuka kwezinga lokushisa. Lapho izinga lokushisa lidlula izinga lokushisa le-gel lomkhiqizo, umkhiqizo uzokhishwa emanzini bese ulahlekelwa i-viscosity yawo. Izinga lokushisa legumbi ehlobo ngokuvamile lingaphezu kwama-degrees angu-30, okuhluke kakhulu ekushiseni kwasebusika, ngakho-ke i-viscosity iphansi. Kunconywa ukukhetha umkhiqizo ono-viscosity ephezulu lapho usebenzisa umkhiqizo ehlobo, noma ukwandisa inani le-cellulose, bese ukhetha umkhiqizo onokushisa okuphezulu kwe-gel.
