I-putty ne-plaster yizinto ezithandwayo ezisetshenziswa kabanzi embonini yezokwakha.Zibalulekile ekulungiseni izindonga nosilingi ukuze kupende, ukuvala imifantu, ukulungisa izindawo ezilimele, nokudala izindawo ezibushelelezi, ezilinganayo.Akhiwe ngezithako ezahlukene ezihlanganisa usimende, isihlabathi, umcako nezinye izithasiselo ukuze zinikeze ukusebenza nezici ezidingekayo.I-Methylhydroxyethylcellulose (MHEC) ingenye yezithako ezibalulekile ezisetshenziselwa ukukhiqizwa kwe-putty ne-plaster powder.Isetshenziselwa ukuthuthukisa izakhiwo ze-powder, ukuthuthukisa izakhiwo zabo zokusebenza nokwandisa izinhlelo zabo zokusebenza.
Izinzuzo zokusebenzisa i-MHEC ukukhiqiza i-putty ne-gypsum powder
I-MHEC itholakala ku-cellulose futhi ikhiqizwa ngenqubo yokuguqulwa kwamakhemikhali.Kuyinhlanganisela encibilikayo emanzini esetshenziswa kabanzi njenge-thickener, stabilizer kanye ne-emulsifier embonini yezokwakha.Uma yengezwe ku-putty kanye ne-gypsum powders, i-MHEC igqoka izinhlayiya, inikeze isendlalelo esivikelayo esibavimbela ekuhlanganiseni nasekuxazululeni.Lokhu kukhiqiza ukuhlanganisa okulinganayo, okungaguquki okulula ukusebenza ngakho futhi kunikeza isiphetho esingcono.
Enye yezinzuzo eziyinhloko zokusebenzisa i-MHEC kuma-putty nama-plasters ukuthi ithuthukisa izindawo zabo zokugcina amanzi.I-MHEC imunca futhi igcine umswakama, iqinisekisa ukuthi imiksi ihlala isebenziseka futhi ayisheshi yome.Lokhu kubaluleke kakhulu ezindaweni ezishisayo nezomile lapho ingxube isheshe ingasebenziseki, okuholela ekuqedeni okubucayi.
I-MHEC iphinde ithuthukise ukusebenza kanye nesikhathi sokusebenza sama-putty namapulasi.I-MHEC yenza ukuhlanganisa nokusebenzisa ingxube kube lula ngokugcina umswakama nokuvimbela ingxube ukuthi yome.Ngaphezu kwalokho, ukuthungwa kwe-MHEC okubushelelezi, okunebhotela kuvumela i-putty ne-stucco ukuthi zisabalale ngokulinganayo phezu kwendawo ngaphandle kokushiya izigaxa noma izigaxa, okuqinisekisa isiphetho esingenasici, esihle.
Ngaphezu kokuthuthukisa ukuthungwa nokusebenza kwama-putty nama-plaster, i-MHEC ingaphinde ithuthukise izakhiwo zabo zokubopha.Ngokwenza ungqimba oluvikelayo ezizungeze izinhlayiya, i-MHEC iqinisekisa ukuthi zibopha kangcono endaweni eziyelaphayo.Lokhu kubangela indawo eqinile, ehlala isikhathi eside futhi mancane amathuba okuthi iqhekeke, ihlehle noma ixebuke ngokuhamba kwesikhathi.
Enye inzuzo ebalulekile yokusebenzisa i-MHEC ku-putty ne-plaster ukuthi kwandisa ukumelana kwabo nomoya kanye nomswakama.Lokhu kusho ukuthi uma i-putty noma i-stucco isetshenziswa, izomelana nomonakalo ovela emoyeni kanye nomswakama, iqinisekise ukuthi ubuso buhlala buqinile futhi bubuhle isikhathi eside.
Ukuthuthukisa Ukusebenza kwe-Putty ne-Gypsum Ukusebenzisa i-MHEC
Ukwandisa ukusebenza kwe-putty ne-plaster powder, kubalulekile ukuqinisekisa ukuthi i-MHEC isetshenziswa ngezilinganiso ezifanele.Lokhu kusho ukuthi ukusebenzisa inani elifanele le-MHEC kungafeza ukusebenza okufunayo kanye nezici ze-putty noma i-stucco ekhiqizwayo.
Izici zemvelo ezingase zithinte ukusebenza kwe-putty ne-gypsum powder kumele zicatshangelwe.Isibonelo, ezindaweni ezishisayo nezomile, i-MHEC eyengeziwe ingase idingeke ukuze kuqinisekiswe ukuthi ingxube ihlala isebenza futhi ingaguquki.
Kubalulekile ukuqinisekisa ukuthi i-putty noma i-stucco isetshenziswa ngendlela efanele ukuze kwandiswe ukusebenza kwayo.Lokhu kusho ukulandela imiyalelo yomkhiqizi ngokucophelela futhi uqinisekise ukuthi ingxube ixubene kahle ngaphambi kokusetshenziswa.Ukwengeza, amathuluzi akhethekile angadingeka ukuze kuqinisekiswe ukuthi i-putty noma i-stucco isetshenziswa ngokulinganayo futhi ngokungaguquki endaweni ephathwayo.
I-MHEC iyisengezo esibalulekile esisetshenziswa ekukhiqizeni i-putty ne-plaster powder.Ithuthukisa izakhiwo kanye nezakhiwo zalezi zinto, ukuthuthukisa ukucutshungulwa kwazo, ukugcinwa kwamanzi, ukunamathela kanye nokumelana nomoya nomswakama.Lokhu kubangela isiphetho esingaguquguquki, esihlala isikhathi eside futhi esikhangayo okungenzeka mancane ukuqhekeka, ukucweba noma ukuxebuka ngokuhamba kwesikhathi.Ukuze kuthuthukiswe ukusebenza kwe-putty ne-gypsum powder, kubalulekile ukuqinisekisa ukuthi isilinganiso esifanele se-MHEC sisetshenziswa, kucatshangelwa izici zemvelo ezingase zithinte ukusebenza kwazo.Ukwengeza, kubalulekile ukusebenzisa i-putty noma i-stucco ngendlela efanele ukuze ukwandise ukusebenza kwayo futhi uzuze imiphumela oyifunayo.
I-HEMC isetshenziselwa ukwakhiwa kukasimende ukuthuthukisa izakhiwo zayo I-Hydroxyethyl methylcellulose (HEMC) iyikhemikhali esetshenziswa kabanzi embonini yezokwakha.Isixhumanisi phakathi kokusebenza, ukugcinwa kwamanzi, i-thixotropy, njll. Namuhla, uhlobo olusha lwe-cellulose ether luthola ukunakwa okwengeziwe.Okudonse ukunakwa okwengeziwe i-hydroxyethyl methylcellulose (MHEC).
Esinye sezici ezibaluleke kakhulu ezinquma izinga lemikhiqizo kasimende ukusebenza kwengxube.Kulula kanjalo usimende ukuxutshwa, ukulolongwa kanye nendawo.Ukufeza lokhu, ingxube kasimende kufanele ibe uketshezi olwanele ukuze ithele futhi igeleze kalula, kodwa futhi kufanele ibe ne-viscous ngokwanele ukuze ibambe ukuma kwayo.I-MHEC ingakwazi ukufeza lesi sakhiwo ngokwandisa i-viscosity kasimende, ngaleyo ndlela ithuthukise ukusebenza kwayo.
I-MHEC ingakwazi futhi ukusheshisa ukufakwa kukasimende futhi ithuthukise amandla ayo.Amandla okugcina usimende ancike enanini lamanzi asetshenziswa ukuwuxuba.Amanzi amaningi azonciphisa amandla kasimende, kuyilapho amanzi amancane kakhulu azokwenza kube nzima kakhulu ukusebenza ngawo.I-MHEC isiza ukugcina inani elithile lamanzi, ngaleyo ndlela iqinisekise i-hydration ephelele ye-samente futhi ikhuthaze ukwakheka kwezibopho eziqinile phakathi kwezinhlayiya ze-cement.
I-MHEC isiza ukunciphisa isibalo sokuqhekeka kukasimende.Njengoba usimende uphulukisa, ingxube iyancipha, okungaholela ekwakhekeni kwemifantu uma ukuncipha kungalawulwa.I-MHEC ivimbela lokhu kuncipha ngokugcina inani elifanele lamanzi ekuxubeni, ngaleyo ndlela ivimbele usimende ekuqhekekeni.
I-MHEC iphinde isebenze njengefilimu evikelayo endaweni usimende, evimbela amanzi ukuthi ahwamuke ebusweni.Le filimu iphinde isize ekugcineni umswakama wokuqala usimende, unciphise nakakhulu amathuba okuqhekeka.
I-MHEC nayo ilungele imvelo.Okokuqala, i-biodegradable, okusho ukuthi ayihlali isikhathi eside endaweni ezungezile.Okwesibili, kungasiza ukunciphisa inani likasimende elidingekayo emisebenzini yokwakha.Lokhu kungenxa yokuthi i-MHEC ikhulisa ukusebenza kanye ne-viscosity kasimende, inciphisa isidingo samanzi engeziwe avele ahlambulule ingxube kasimende.
Ukusetshenziswa kwe-MHEC kusimende kunikeza izinzuzo ezimbalwa futhi kungaba negalelo elikhulu embonini yezokwakha.Ithuthukisa ukusebenza kwengxube kasimende, inciphisa inani lemifantu eyakhiwe ngesikhathi sokuphulukiswa, ikhuthaza ukugeleza kukasimende namandla, futhi yenza njengefilimu evikelayo endaweni usimende.Ukwengeza, i-MHEC ilungele imvelo.Ngakho-ke, i-MHEC ingumkhiqizo obalulekile embonini yezokwakha njengoba ithuthukisa izinga likasimende futhi inikeza izinzuzo kubasebenzi kanye nemvelo.
