UPutty noPlaster bayizinto ezithandwayo ezisetshenziswa kabanzi embonini yezokwakha. Babalulekile ekulungiseleleni izindonga nophahla lokupenda, ukumboza imifantu, ukulungisa izindawo ezilimele, nokwakha okubushelelezi, ngisho nokubukeka. Bahlanganiswa izithako ezahlukahlukene kufaka phakathi usimende, isihlabathi, i-lime nezinye izengezo ukuhlinzeka ngokwenza kanye nezimpawu ezidingekayo. I-methylydroxyyylcelcellellose (Mhec) ingenye yezithasiselo ezisemqoka ezisetshenziswa ekukhiqizweni kwe-putty ne-powsaster powder. Kusetshenziselwa ukuthuthukisa izakhiwo zama-powders, kuthuthukise izakhiwo zazo zokusebenza nokwandisa izinhlelo zazo.
Izinzuzo zokusebenzisa i-MHEC ukukhiqiza i-putty ne-gypsum powder
I-MHEC isuselwa ku-cellulose futhi ikhiqizwe ngenqubo yokuguqulwa kwamakhemikhali. Yikhompiyutha engenakuthelwa amanzi esetshenziswa kabanzi njengomuntu omkhulu, i-stabilizer kanye ne-emulsifier embonini yezokwakha. Uma ungezwe kuma-putty and gypsum powders, i-MheC ihalalisela izinhlayiya, ukuhlinzeka ngongqimba oluvikelayo olubavimbela ekuhlolweni nasekuxazululeni. Lokhu kukhiqiza umxube kakhudlwana ngisho, okulula ukusebenza nakho futhi kunikeza ukuqeda okungcono.
Enye yezinzuzo eziphambili zokusebenzisa i-MHEC kuma-tutties kanye nama-plasters ukuthi kuthuthukisa izakhiwo zazo zokugcina amanzi. I-Mhec Amuscorbs futhi igcine umswakama, ukuqinisekisa ukuxuba kuhlala kungasebenziseka futhi akusomile ngokushesha okukhulu. Lokhu kubaluleke kakhulu ezindaweni ezishisayo nezomile lapho ingxube isheshe iba khona, okuholela ekuqedeni okungekho emthethweni.
I-MHEC ibuye ithuthukise ukusebenziseka kanye nesikhathi sokusebenza sama-tupties nama-plasters. I-MHEC yenza ukuxubana nokusebenzisa le ngxube kube lula ngokugcina umswakama nokuvimbela ingxube ekumisweni komiswa. Ngaphezu kwalokho, ukuthungwa okubushelelezi kweMhec, ubuthi buvumela ukubeka uPutty neStucco ukusabalala ngokulinganayo ngaphezulu kobuso ngaphandle kokushiya izigaxa noma ama-clumps, ukuqeda okungekho emthethweni.
Ngaphezu kokuthuthukisa ukuthungwa kanye nokusebenza kwama-tupties nama-plasters, i-MHEC nayo ingathuthukisa izakhiwo zayo zokubopha. Ngokwakha ungqimba oluvikelayo azungeze izinhlayiya, i-MHEC iqinisekisa ukuthi bahlangana kangcono ebusweni bakwelapha. Lokhu kuphumela endaweni enamandla, eqinile kakhudlwana okungase kukhule, chip noma amakhasi ngokuhamba kwesikhathi.
Enye inzuzo ebalulekile yokusebenzisa i-MHEC ngesiPututy noPlaster ukuthi kwandisa ukumelana kwabo nomoya nomswakama. Lokhu kusho ukuthi uma uPutty noma iStucco noma isetshenziswa, izokwenqaba ukulimala kusuka emoyeni nasemswakama, kuqinisekisa ukuthi ingaphezulu lihlala lihlala isikhathi eside futhi lihle isikhathi eside.
Ukulungiselela ukusebenza kwama-putty kanye ne-gypsum usebenzisa i-mhec
Ukwenza kahle ukusebenza kwe-putty ne-polaster powder, kubalulekile ukuqinisekisa ukuthi i-MHEC isetshenziswa ngezilinganiso ezifanele. Lokhu kusho ukuthi ukusebenzisa inani elifanele le-MHEC kungafinyelela ukusebenza okufunayo kanye nezimpawu ze-putty noma i-stucco ekhiqizwayo.
Izici zezemvelo ezingathinta ukusebenza kwe-putty ne-gypsum powder kufanele kubhekwe. Isibonelo, ezindaweni ezishisayo nezomile, ngaphezulu kwe-Mhec kungadinga ukungezwa ukuze kuqinisekiswe ukuthi ingxube ihlala isebenza futhi iyavumelana.
Kubalulekile ukuqinisekisa ukuthi i-putty noma i-stucco isetshenziswa kahle ukukhulisa ukusebenza kwayo. Lokhu kusho ukulandela imiyalo yomenzi ngokucophelela futhi uqiniseke ukuthi ingxube ixubene kahle ngaphambi kokusebenzisa. Ngaphezu kwalokho, amathuluzi akhethekile angacelwa ukuthi aqinisekise ukuthi i-Putty noma iStucco isetshenziswa ngokulinganayo futhi ngokungaguquki ebusweni belashwa.
I-MHEC isengezo esibalulekile esisetshenziswa ekukhiqizeni i-putty ne-powder powsar. Kuthuthukisa izakhiwo nezakhiwo zalezi zinto zokwenziwa, ukuthuthukisa ukucubungulwa kwazo, ukugcinwa kwamanzi, ukunamathela kanye nokumelana nomoya nomswakama. Lokhu kuphumela ekuqedeni okungaguquki, okuhlala isikhathi eside futhi okukhangayo okungase kukhule, chip noma amakhasi ngokuhamba kwesikhathi. Ukuze wandise ukusebenza kwe-putty ne-gypsum powder, kubalulekile ukuqinisekisa ukuthi umthamo ofanele we-MHEC uyasetshenziswa, kucatshangelwa izici zezemvelo ezingathinta ukusebenza kwazo. Ngokwengeziwe, kubalulekile ukusebenzisa i-putty noma i-stucco kahle ukuze wandise ukusebenza kwayo futhi uzuze imiphumela oyifunayo.
IHemc isetshenziswa ekwakhiweni kosesimende ukuthuthukisa izakhiwo zayo i-hydroxyyethyll methylcellulose (hemc) ingamakhemikhali asetshenziswa kabanzi embonini yezokwakha. Kungumsebenzi phakathi kokusebenza, ukugcinwa kwamanzi, i-thixotropy, njll. Namuhla, uhlobo olusha lwe-cellulose ether luthola ukunakwa okwengeziwe. Okuheha ukunakwa okwengeziwe yi-hydroxyethyll methylcellulose (Mhec).
Enye yezinto ezibaluleke kakhulu ezinquma ikhwalithi yemikhiqizo yesimende ukusebenziseka kwengxube. Yile ndlela usimende olula ngayo ukuxuba, ukwakheka nendawo. Ukufeza lokhu, ingxube kasimende kufanele kube uketshezi ngokwanele ukuwathela nokugeleza kalula, kepha kufanele futhi kube nokuningiliswe ngokwanele ukubamba ukwakheka kwalo. I-MHEC ingafinyelela le mpahla ngokwandisa i-viscosity ye-clean, ngaleyo ndlela ithuthukise ukusebenziseka kwayo.
I-MHEC nayo ingasheshisa i-hydration kasimende futhi ithuthukise amandla ayo. Amandla okugcina kasimende ancike kwinani lamanzi asetshenziselwa ukulixuba. Amanzi amaningi azonciphisa amandla kasimende, ngenkathi amanzi amancane kakhulu azokwenza kube nzima kakhulu ukusebenza nawo. I-MHEC isiza ukugcina inani elithile lamanzi, ngaleyo ndlela liqinisekise ukuthi i-hydration efanelekile yokhonkolo futhi ithuthukise ukwakheka kwamabhondi aqinile phakathi kwezinhlayiya zomoya.
I-MHEC isiza ukunciphisa inani lokuqhekeka kosimende. Njengoba ukwelashwa kwesimende, ingxube iyancipha, okungaholela ekwakhekeni kwemifantu uma i-shrinkage ingalawulwa. I-MheC ivimbela le shrinkage ngokugcina inani elifanele lamanzi ku-mix, ngaleyo ndlela kuvinjelwe usimende kusuka ekuqhekekeni.
I-MHEC ibuye isebenze njengefilimu evikelayo endaweni eseyili, ivimbela amanzi ekutholeni ebusweni. Le filimu nayo isiza ukugcina umswakama wokuqala usimende, uphinde unciphise ithuba lokuqhekeka.
I-MHEC nayo ilungele imvelo. Okokuqala, kuyinto eyingqayizivele, okusho ukuthi akuhlali emvelweni isikhathi eside. Okwesibili, kungasiza ukunciphisa inani likasimende oludingekayo kumaphrojekthi wokwakha. Lokhu kungenxa yokuthi i-MHEC inyusa ukusebenziseka nokubonakala kosimende, ukunciphisa isidingo samanzi angeziwe amane anciphise ingxube kasimende.
Ukusetshenziswa kwe-MHEC kuCement kunikeza izinzuzo eziningana futhi kungafaka isandla ebalulekile embonini yezokwakha. Kuthuthukisa ukusebenziseka kwengxube kasimende, kunciphisa inani lokuqhekeka okwenziwe ngesikhathi sokuphulukisa, kukhuthaza i-hydration namandla kasimende namandla, futhi kusebenza njengefilimu evikelayo endaweni evuthayo. Ngaphezu kwalokho, i-MHEC ilungele imvelo. Ngakho-ke, i-MHEC ingumkhiqizo obalulekile embonini yezokwakha njengoba ithuthukisa ikhwalithi kasimende futhi ihlinzeka ngezinzuzo kubasebenzi kanye nemvelo.
