Sekungamakhulu eminyaka, amatshe amatshe kanye ne-plaster asetshenziselwa ukwakha izakhiwo ezinhle nezihlala isikhathi eside. Lezi zingosi zenziwa ngengxube kasimende, isihlabathi, amanzi nezinye izithasiselo. IHydroxypropyl methylcellulose (HPMC) iyisengezo esinjalo.
I-HPMC, eyaziwa nangokuthi i-hypromellose, iyi-ether ye-cellulose eguquliwe etholakala ku-pulp yokhuni nemicu kakotini. Kuyisithako esisebenza ngezindlela eziningi esisetshenziswa ezimbonini ezahlukahlukene, okubandakanya ezokwakha, ezemithi, ukudla kanye nemikhiqizo yokunakekela umuntu. Emkhakheni wezokwakha, i-HPMC isetshenziswa njenge-thickener, binder, i-ejenti yokugcina amanzi kanye ne-rheology modifier ekwenziweni kodaka.
Iqhaza le-HPMC ku-masonry plastering mortar
1. Ukulawula ukungaguquguquki
Ukungaguquguquki kodaka kubalulekile ekusetshenzisweni okufanele nokubopha. I-HPMC isetshenziselwa ukugcina ukuvumelana okudingekayo kodaka lwamatshe kanye nodaka. Isebenza njenge-thiener, ivimbela udaka ekubeni luketshezi kakhulu noma lube lukhulu, okuvumela ukusebenza kahle.
2. Ukugcinwa kwamanzi
Amanzi abalulekile enqubweni yokufakwa kwamanzi kukasimende, ingxenye ebalulekile yokwakhiwa kwamatshe kanye nodaka lokuplasta. Nokho, amanzi amaningi kakhulu angabangela ukushwabana nokuqhekeka. I-HPMC isiza ukugcina umswakama odongeni, ivumela ukugeleza okufanele kukasimende ngenkathi yehlisa ukulahlekelwa kwamanzi ngokuhwamuka. Lokhu kubangela ukusebenza okuthuthukisiwe, ukunamathela okungcono namandla andayo.
3. Hlela isikhathi
Isikhathi sokumisa sodaka sithinta ukuqina nokunamathela kwesakhiwo sokugcina. I-HPMC ingasetshenziswa ukulawula isikhathi sokumiswa kwamatshe kanye nodaka lokuplasta. Isebenza njenge-retarder, inciphisa inqubo ye-hydration kasimende. Lokhu kubangela isikhathi eside sokusebenza kanye nokusebenza okuthuthukisiwe kokubopha.
4. Amandla okunamathela
Amandla esibopho sodaka abalulekile ekuqineni kwezakhiwo zamatshe kanye ne-plaster. I-HPMC ithuthukisa amandla esibopho phakathi kodaka ne-substrate ngokunikeza ukunamathela okungcono nokusebenza okuthuthukisiwe. Lokhu kubangela isakhiwo esiqinile futhi esihlala isikhathi eside.
Izinzuzo ze-HPMC ku-masonry kanye nodaka lokuplasta
1. Thuthukisa ukusebenza
I-HPMC isiza ukwenza ngcono ukusebenza kokwakhiwa kwamatshe nodaka. Izakhiwo ezijiyayo nezigcina amanzi ze-HPMC zenza ukusetshenziswa kodaka kube lula futhi kube lula. Lokhu kwandisa ukusebenza kahle kanye nesivinini sokwakha.
2. Yehlisa ukushwabana nokuqhekeka
Ukuncipha kanye nokuqhekeka yizinkinga ezivamile ngokwakhiwa kwamatshe okuvamile kanye nodaka lwe-plaster. Izakhiwo ezigcina amanzi ze-HPMC zinciphisa ukuhwamuka futhi zinqande ukushwabana nokuqhekeka. Lokhu kubangela isakhiwo esiqinile nesihlala isikhathi eside.
3. Thuthukisa ukuqina
Ukwengezwa kwe-HPMC kumamasonry kanye nodaka lokuplasta kuthuthukisa ukuqina kwesakhiwo sokugcina. I-HPMC ithuthukise amandla ebhondi, ukucutshungulwa kanye nokugcinwa kwamanzi, okuholela ekwakhekeni okuqinile, okuhlala isikhathi eside.
4. Ukusebenza kwezindleko eziphezulu
I-HPMC iyisengezo esingabizi kakhulu esinikeza izinzuzo eziningi ekubunjweni kodaka nodaka. Izakhiwo zayo zinciphisa ingozi yezinkinga ezifana nokuncipha nokuqhekeka, ngaleyo ndlela kuncishiswe izindleko zokulondoloza impilo yonke yesakhiwo.
Ekuphetheni
I-HPMC idlala indima ebalulekile ekuthuthukiseni ukusebenza kanye nokusebenza kodaka kanye nodaka lokuplasta. Ukulawulwa kwayo ngokungaguquguquki, ukugcinwa kwamanzi, ukusetha isikhathi sokulawula kanye nezakhiwo zamandla ebhondi kunikeza izinzuzo eziningi embonini yezokwakha. Ukusetshenziswa kwe-HPMC kuholela ekusebenzeni okuthuthukisiwe, ukunciphisa ukushwabana nokuqhekeka, ukuqina okuthuthukisiwe kanye nokwakhiwa okungabizi kakhulu. Ukufakwa kwe-HPMC kumamasonry kanye nokuhlinzeka ngodaka kuyisinyathelo esihle esiya ezindleleni zokwakha ezisebenza kahle, ezisimeme nezihlala isikhathi eside.
