Indima ye-HPMC ekwenzeni iimasonry kunye nodaka lokutyabeka

Kangangeenkulungwane, i-masonry kunye ne-plaster mortars ziye zasetyenziselwa ukudala izakhiwo ezintle kunye nezizinzileyo.Olu daka lwenziwe ngomxube wesamente, isanti, amanzi kunye nezinye izongezo.IHydroxypropyl methylcellulose (HPMC) sesinye esongezo.

I-HPMC, ekwabizwa ngokuba yi-hypromellose, yi-etha yeselulosi elungisiweyo ephuma kwintlama yeplanga kunye nemicu yomqhaphu.Sisithako esisebenzisekayo esisetyenziswa kumashishini ahlukeneyo, kubandakanya ukwakhiwa, amayeza, ukutya kunye neemveliso zokhathalelo lomntu.Kwicandelo lokwakha, i-HPMC isetyenziswa njenge-thickener, i-binder, i-arhente yokugcina amanzi kunye ne-rheology modifier kwi-formulation yodaka.

Indima ye-HPMC kwi-masonry plastering udaka

1. Ukulawula ukuhambelana

Ukuhambelana kodaka kubalulekile ekusetyenzisweni okufanelekileyo kunye nokudibanisa.I-HPMC isetyenziselwa ukugcina ukuhambelana okufunekayo kwe-masonry kunye ne-plaster mortars.Isebenza njenge-thickener, ithintela udaka ekubeni lube lulwelo kakhulu okanye lube lukhuni, luvumela ukusetyenziswa okugudileyo.

2. Ukugcinwa kwamanzi

Amanzi abalulekile kwinkqubo yokufakwa kwamanzi kwisamente, eyona nxalenye ibalulekileyo yokwakhiwa kweemasonry kunye nodaka lokutyabeka.Nangona kunjalo, amanzi amaninzi anokubangela ukushwabana kunye nokuqhekeka.I-HPMC inceda ukugcina ukufuma kudaka, ivumela ukugalela kwamanzi ngendlela eyiyo kwesamente ngelixa inciphisa ilahleko yamanzi ngokuba ngumphunga.Oku kubangela ukuphuculwa kokusebenza, ukunamathela okungcono kunye nokunyuka kwamandla.

3. Beka ixesha

Ixesha lokumisela lomdaka lichaphazela ukuqina kunye nokunamathela kwesakhiwo sokugqibela.I-HPMC ingasetyenziselwa ukulawula ixesha lokumisela i-masonry kunye nodaka lokutyabeka.Isebenza njenge-retarder, inciphisa inkqubo ye-hydration ye-samente.Oku kubangela ixesha elide lokusebenza kunye nokusebenza okuphuculweyo kokubambisana.

4. Amandla okubambelela

Amandla ebhondi yodaka abalulekile ekomeleleni kobume bamatye kunye nezakhiwo zodaka.I-HPMC yongeza amandla okudibanisa phakathi kodaka kunye ne-substrate ngokubonelela ngokunamathela okungcono kunye nokusebenza okuphuculweyo.Oku kubangela isakhiwo esomeleleyo kunye nesigxina.

Izinto ezilungileyo ze-HPMC kwi-masonry kunye nodaka lokutyabeka

1. Ukuphucula ukusebenza

I-HPMC inceda ukuphucula ukusebenza kobume kunye nodaka lokutyabeka.Ukujiya kunye neempawu zokugcina amanzi ze-HPMC zenza ukusetyenziswa kodaka kube lula kwaye kube lula.Oku kwandisa ukusebenza kakuhle kunye nesantya sokwakha.

2. Nciphisa i-shrinkage kunye nokuqhekeka

I-Srinkage kunye nokuqhekeka ziingxaki eziqhelekileyo kunye ne-masonry yendabuko kunye ne-plaster mortars.Iipropati zokugcina amanzi ze-HPMC zinciphisa ukuguquka kwamanzi kwaye zithintele ukushwabana kunye nokuqhekeka.Oku kubangela isakhiwo esihlala sihleli kwaye sihlala ixesha elide.

3. Ukomeleza ukuqina

Ukongezwa kwe-HPMC kwimasonry kunye nodaka lokutyabeka kwandisa ukuqina kwesakhiwo sokugqibela.I-HPMC iye yaphucula amandla ebhondi, ukusetyenzwa kunye nokugcinwa kwamanzi, okubangela ukuba kube namandla, isakhiwo esihlala ixesha elide.

4. Ukusebenza kweendleko eziphezulu

I-HPMC lulongezelelo olungabizi kakhulu olubonelela ngeenzuzo ezininzi kubumesri kunye nokwenziwa kodaka lodaka.Iipropati zayo zinciphisa umngcipheko weengxaki ezifana nokunciphisa kunye nokuqhekeka, ngaloo ndlela ukunciphisa iindleko zokulondoloza ubomi bonke besakhiwo.

ukuququmbela

I-HPMC idlala indima ebalulekileyo ekuphuculeni ukusebenza kunye nokusebenza kweemasonry kunye nodaka lokutyabeka.Ulawulo lwayo olungaguquguqukiyo, ukugcinwa kwamanzi, ulawulo lwexesha lokumisela kunye neempawu zamandla ebhondi zibonelela ngeenzuzo ezininzi kushishino lokwakha.Ukusetyenziswa kwe-HPMC kubangela ukuphuculwa kokusebenza, ukunciphisa ukucutheka kunye nokuqhekeka, ukomeleza ukuqina kunye nokwakhiwa kweendleko.Ukudityaniswa kwe-HPMC kubumesli kunye nokunikezela ngodaka linyathelo elilungileyo elisingise kwiindlela zokwakha ezisebenza ngempumelelo, ezizinzileyo nezizinzileyo.
