Kangangeenkulungwane, ii-mortar ezenziwe ngomthi kunye ne-plaster bezisetyenziswa ukwenza izakhiwo ezintle nezihlala ixesha elide. Ezi mortar zenziwe ngomxube wesamente, isanti, amanzi kunye nezinye izongezo. I-Hydroxypropyl methylcellulose (HPMC) yenye yezo zongezo.
I-HPMC, eyaziwa ngokuba yi-hypromellose, yi-modified cellulose ether ephuma kwi-pulp yomthi kunye ne-cotton fibers. Sisithako esisetyenziswa ngeendlela ezahlukeneyo kumashishini ahlukeneyo, kuquka ulwakhiwo, amayeza, ukutya kunye neemveliso zokhathalelo lomntu. Kwicandelo lokwakha, i-HPMC isetyenziswa njengesithambisi, isibambi, iarhente yokugcina amanzi kunye nesiguquli se-rheology kwi-mortar formulations.
Indima ye-HPMC kwi-masonry plastering mortar
1. Ulawulo lokungaguquguquki
Ukuqina kwesamente kubalulekile ekusetyenzisweni nasekubotshelelweni ngokufanelekileyo. I-HPMC isetyenziselwa ukugcina ukuqina okufunekayo kwesamente kunye nesamente. Isebenza njengesithambisi, ithintela isamente ukuba singabi manzi kakhulu okanye sibe ngqindilili, nto leyo evumela ukusetyenziswa kwayo kube lula.
2. Ukugcinwa kwamanzi
Amanzi abalulekile kwinkqubo yokufunxa isamente, into ebalulekileyo kwi-masonry kunye ne-plastering mortars. Nangona kunjalo, amanzi amaninzi anokubangela ukushwabana nokuqhekeka. I-HPMC inceda ukugcina umswakama kwi-mortar, ivumela ukufunxa ngokufanelekileyo isamente ngelixa inciphisa ukulahleka kwamanzi ngokuphuma komphunga. Oku kuphumela ekusebenzeni ngcono, ukunamathela okungcono kunye namandla angakumbi.
3. Beka ixesha
Ixesha lokubeka i-mortar lichaphazela ukuqina kunye nokunamathela kwesakhiwo sokugqibela. I-HPMC ingasetyenziselwa ukulawula ixesha lokubeka i-mortars yobumba kunye ne-plaster. Isebenza njenge-retarder, icothisa inkqubo yokufunxa isamente. Oku kuphumela kwixesha elide lokusebenza kunye nokusebenza okuphuculweyo kokubopha.
4. Amandla okuncamathela
Amandla okubopha kweemortar abaluleke kakhulu ekuqineni kwezakhiwo zobumba kunye neplasta. I-HPMC yonyusa amandla okubopha phakathi kwemortar kunye ne-substrate ngokubonelela ngokunamathela okungcono kunye nokusebenza ngcono. Oku kuphumela kwisakhiwo esomeleleyo nesihlala ixesha elide.
Iingenelo ze-HPMC kwiimayini kunye neeplasta zemortars
1. Phucula ukusebenza kakuhle
I-HPMC inceda ekuphuculeni ukusebenza kakuhle kwee-mortars ezenziwe ngomthi kunye neplasta. Iipropati zokuqina kunye nokugcina amanzi ze-HPMC zenza ukusetyenziswa kwe-mortar kube lula kwaye kube lula. Oku kwandisa ukusebenza kakuhle kunye nesantya sokwakha.
2. Nciphisa ukushwabana nokuqhekeka
Ukushwabana nokuqhekeka ziingxaki eziqhelekileyo kwiimota zemveli zokwakha nokwakha ngeplasta. Iimpawu zokugcina amanzi zeHPMC zinciphisa ukufuma kwaye zithintela ukushwabana nokuqhekeka. Oku kuphumela kwisakhiwo esihlala ixesha elide nesihlala ixesha elide.
3. Yandisa ukuqina
Ukongezwa kwe-HPMC kwii-mortars zokwakha kunye ne-plastering kwandisa ukuqina kwesakhiwo sokugqibela. I-HPMC iphucule amandla e-bond, ukuqhubekeka kokusebenza kunye nokugcinwa kwamanzi, nto leyo ekhokelela kwisakhiwo esomeleleyo nesihlala ixesha elide.
4. Ukusebenza ngexabiso eliphezulu
I-HPMC sisongezelelo esingabizi kakhulu esibonelela ngeenzuzo ezininzi kwizakhiwo zobumba kunye nokuplasta. Iimpawu zayo zinciphisa umngcipheko weengxaki ezinje ngokushwabana nokuqhekeka, ngaloo ndlela zinciphisa iindleko zokulungisa ubomi bonke besakhiwo.
ukuququmbela
I-HPMC idlala indima ebalulekileyo ekuphuculeni ukusebenza kunye nokusebenza kwee-mortars zokwakha kunye ne-plastering. Ulawulo lwayo lokungaguquguquki, ukugcinwa kwamanzi, ulawulo lwexesha lokubeka kunye neempawu zokuqina kwebhondi zibonelela ngeenzuzo ezininzi kwishishini lokwakha. Ukusetyenziswa kwe-HPMC kuphumela ekuphuculweni kokusebenza, ukunciphisa ukuncitshiswa kunye nokuqhekeka, ukuqina okuphuculweyo kunye nokwakhiwa okungabizi kakhulu. Ukufakwa kwe-HPMC kwii-mortars zokwakha kunye ne-render linyathelo elihle eliya kwiindlela zokwakha ezisebenzayo, ezizinzileyo nezihlala ixesha elide.
