I-putty powder iyimpahla yokwakha edumile esetshenziselwa ukugcwalisa izikhala, imifantu kanye nezimbobo endaweni ngaphambi kokupenda noma ukufaka amathayela. Izithako zayo ngokuyinhloko zakhiwe i-gypsum powder, i-talcum powder, amanzi nezinye izinto. Kodwa-ke, ama-putty akhiwe yesimanje nawo aqukethe isithako esengeziwe, i-hydroxypropyl methylcellulose (HPMC). Lesi sihloko sizoxoxa ngokuthi kungani sengeza i-HPMC ku-putty powder kanye nezinzuzo ezilethayo.
IHydroxypropyl methylcellulose iyi-polymer encibilika emanzini etholakala ku-cellulose, ingxenye eyinhloko yezindonga zamaseli ezitshalo. Isetshenziswa kabanzi ezimbonini ezahlukahlukene ezifana nezokwakha, ezemithi, izindwangu nezokudla. Ekwakhiweni, isetshenziswa njengesithako kuma-mortars, ama-grouts, amapende nama-putty.
Ukwengeza i-HPMC ku-putty powder kunezinzuzo ezilandelayo:
1. Khulisa ukugcinwa kwamanzi
I-HPMC iyi-polymer eyi-hydrophilic edonsa futhi igcine ama-molecule amanzi. Ukwengeza i-HPMC ku-putty powder kungathuthukisa ukusebenza kwayo kokugcinwa kwamanzi. Ngesikhathi sokwakhiwa, i-putty powder exutshwe ne-HPMC ngeke yome ngokushesha, inikeze abasebenzi isikhathi esanele sokusingatha izinto futhi igcwalise ngempumelelo izikhala ngaphandle kokubangela ukuthi izinto ziqhekeke noma zinciphise. Kanye nokugcinwa kwamanzi okwandisiwe, ama-putty powders nawo abopha kahle endaweni, enciphisa amathuba okuqhekeka noma ukuxebuka.
2. Thuthukisa ukusebenza
Impushana ixutshwa ne-HPMC ukuze kwakheke ukuvumelana okufana nokunamathisela, okwenza kube lula ukukusebenzisa nokusabalalisa ezindaweni zonke. I-HPMC inika ama-putty powders ukuthungwa okushelelayo, anikeze isiphetho esingcono uma kupenda noma kufakwa amathayela. Iphinde inikeze i-putty inani lesivuno esiphezulu, ikhono lokumelana nokuguqulwa ngaphansi kwengcindezi. Lokhu kusho ukuthi i-putty powder exutshwe ne-HPMC ingabunjwa kalula futhi ibunjwe ukuze ivumelane nezindawo ezihlukahlukene.
3. Yehlisa ukushwabana nokuqhekeka
Njengoba kushiwo ngaphambili, i-HPMC ingathuthukisa ukugcinwa kwamanzi kwe-putty powder. Ngenxa yalokho, i-putty powder mancane amathuba okuthi yome ngokushesha uma isetshenziswa endaweni engaphezulu, okubangela ukuncipha nokuqhekeka. I-HPMC iphinde isize ekunciphiseni ukushwabana nokuqhekeka ngoba ikhulisa amandla ebhondi empushana ephutshayo, okwenza izinto zizinze futhi zingabi lula ukuqhekeka.
4. Ukumelana kangcono nokushintsha kwamanzi nezinga lokushisa
I-putty powder exutshwe ne-HPMC inokumelana kangcono namanzi kanye nokushintsha kwezinga lokushisa kune-putty powder ngaphandle kwe-HPMC. I-HPMC iyi-polymer eyi-hydrophilic evikela ama-putty powders ekushintsheni kwezinga lokushisa nomswakama. Lokhu kusho ukuthi i-putty powder exutshwe ne-HPMC ihlala isikhathi eside futhi ingamelana nokuchayeka ezimweni zezulu ezahlukahlukene.
5. Impilo yeshalofu ende
Ukwengeza i-HPMC ku-putty powder kungandisa impilo yayo yeshalofu. I-HPMC ivimbela ama-putty powder ukuthi ome futhi aqine ngesikhathi sokugcina. Lokhu kusho ukuthi i-putty powder exutshwe ne-HPMC ingagcinwa isikhathi eside ngaphandle kokulahlekelwa ikhwalithi noma ingasetshenziswa.
Ukufingqa, ukwengeza i-HPMC ku-putty powder kunezinzuzo ezimbalwa. Yandisa ukugcinwa kwamanzi, ithuthukisa ukucutshungulwa, inciphisa ukushwabana nokuqhekeka, inikeza ukumelana okungcono namanzi nezinga lokushisa, futhi yandisa ukuphila kweshalofu. Zonke lezi zinzuzo ziqinisekisa ukuthi i-putty powder exutshwe ne-HPMC izohlinzeka ngokuqeda okungcono futhi ihlale isikhathi eside. Ngakho-ke, kuyisici esibalulekile esinomthelela empumelelweni yanoma yimuphi umsebenzi wokwakha.
Sekukonke, ukusetshenziswa kwe-HPMC kuma-putty powders kuyintuthuko enhle embonini yezokwakha. Inikeza izinzuzo eziningi ezisiza ukwenza umsebenzi wawo wonke umuntu ube lula, uphumelele futhi usebenze kahle. Ukuqhubeka nokusetshenziswa kwayo kungase kuholele ekuthuthukisweni okusha okuqhubekisela phambili ukuthuthukisa ikhwalithi yezinto zokwakha kanye nezinqubo zokwakha.
