Ukusetshenziswa kweHydroxypropyl Methyl Cellulose Emikhiqizweni Yezinto Zokwakha Ezihlukahlukene

IHydroxypropyl Methyl Cellulose (HPMC) iyi-polymer eguquguqukayo ethola ukusetshenziswa okubanzi ezintweni zokwakha ezahlukahlukene ngenxa yezakhiwo zayo ezihlukile.Le nto ephuma ku-cellulose ether isuselwa ku-cellulose yemvelo futhi isetshenziswa kakhulu emikhiqizweni yokwakha ngokugcina amanzi, ukujiya, kanye namandla okubopha.

1. Isingeniso se-Hydroxypropyl Methyl Cellulose (HPMC)

IHydroxypropyl Methyl Cellulose iyi-ether engeyona ionic cellulose etholakala ngokwelapha i-cellulose yemvelo nge-propylene oxide ne-methyl chloride.Iyancibilika emanzini futhi yakha isixazululo esisobala, esine-viscous.Imvelo eguquguqukayo ye-HPMC ivela ekhonweni layo lokuguqula izakhiwo ze-rheological, ukugcinwa kwamanzi, nokunamathela ezintweni zokwakha.

2. Izicelo ku-Mortar

2.1.Ukugcina Amanzi

I-HPMC ijwayele ukusetshenziswa ekwenziweni kodaka ukuze kuthuthukiswe ukugcinwa kwamanzi.Imvelo yayo eyi-hydrophilic ivumela ukuthi imunce futhi igcine amanzi, ivimbele ukomiswa kodaka ngaphambi kwesikhathi.Lesi sakhiwo siqinisekisa ukusebenza okungcono, isikhathi sokusetha eside, kanye nokunamathela okuthuthukisiwe kuma-substrates.

2.2.Ukujiya kanye nokulawula i-Rheology

Ukwengezwa kwe-HPMC ekwakhekeni kodaka kunikeza izici ezifiselekayo zokujiya, kube nomthelela ekuziphatheni kwe-rheological kwengxube.Lokhu kubalulekile ukuze kube lula ukusetshenziswa kanye nokufeza ukuvumelana okufunayo odakeni.

2.3.Ukunamathela Okuthuthukisiwe

Ukufaka i-HPMC odakeni kuthuthukisa ukunamathela ezindaweni ezihlukahlukene, okunikela emandleni ewonke kanye nokuqina kwempahla yokwakha.Lokhu kubaluleke kakhulu ezinhlelweni ezifana nokufakwa kwamathayela e-ceramic.

3. Izicelo ku-Tile Adhesives kanye namaGrouts

3.1.Ukusebenza Okuthuthukisiwe

Okunamathelayo kwethayela kuvame ukuqukatha i-HPMC ukuze kuthuthukiswe ukusebenza kahle nesikhathi esivulekile.I-polymer iqinisekisa ukuthi okunamathelayo kuhlala kusesimweni esisebenzayo isikhathi eside, okuvumela ukubekwa kwamathayili ngendlela efanele ngaphandle kokoma ngaphambi kwesikhathi.

3.2.Ukuncishiswa Kwehlisa

I-HPMC inikela ezenzweni zokunqanda ukunyakaza kwezinamathelisi zamathayili.Lokhu kubalulekile uma ufaka amathayela ezindaweni eziqondile, njengoba kuvimbela amathayela ukuthi angasheleli phansi ngaphambi kokuba okunamathiselwe kumiswe.

3.3.Ukumelana ne-Crack ku-Grouts

Ekwenziweni kwe-grout, i-HPMC isiza ukuvimbela ukuqhekeka ngokunikeza ukuguquguquka nokunciphisa ukushwabana.Lokhu kunenzuzo ikakhulukazi ezindaweni lapho ukuhlukahluka kwezinga lokushisa kungathinta izinto zokwakha.

4. Izicelo kuPlaster

4.1.Ukusebenza Okuthuthukisiwe Nokusabalala

I-HPMC ivamise ukungezwa ekwakhiweni kukakhonkolo ukuze kuthuthukiswe ukusebenza nokusabalala.I-polymer isiza ukufeza ukusetshenziswa okushelelayo nokungaguquguquki kwe-plaster ezindaweni ezingaphezulu.

4.2.I-Crack Resistance

Ngokufana nendima yayo kuma-grouts, i-HPMC inomthelela ekwandeni kokuqhekeka ku-plaster.Yakha ifilimu eguquguqukayo evumela ukunyakaza kwemvelo kwezinto zokwakha, ukunciphisa amathuba okuqhekeka.

5. Izicelo Ezihlanganisweni Zokuzilinganisa

5.1.Ukulawula Ukugeleza

Kumakhompiyutha okuzilinganisa, i-HPMC isetshenziselwa ukulawula ukugeleza nokubeka izinga.I-polymer iqinisekisa ukusatshalaliswa okufanayo futhi isiza ukugcina ukujiya okufunayo kwenhlanganisela kuyo yonke indawo yohlelo lokusebenza.

5.2.Ukunamathela Okuthuthukisiwe

I-HPMC ithuthukisa ukunamathela kwezinhlanganisela zokuzilinganisa kuma-substrates ahlukahlukene, inikeze isibopho esiqinile nesihlala isikhathi eside.Lokhu kubalulekile ekusebenzeni kwesikhathi eside kwendawo esezingeni.

6. Isiphetho

IHydroxypropyl Methyl Cellulose idlala indima ebalulekile ekuthuthukiseni ukusebenza kwempahla yokwakha eyahlukene.Ukufakwa kwayo odakeni, okunamathelisa amathayela, ama-grouts, ukhonkolo, nezinhlanganisela ezizilinganisayo kukhombisa ukuguquguquka kwayo nokusebenza ngempumelelo embonini yezokwakha.Izakhiwo ezihlukile ze-HPMC, ezihlanganisa ukugcinwa kwamanzi, ukujiya, nokunamathela okuthuthukisiwe, zifaka isandla kukhwalithi iyonke, ukuqina, nokusebenza kwalezi zinto zokwakha.Njengoba imboni yezokwakha iqhubeka nokuvela, i-HPMC isalokhu iyisithako esibalulekile ekwakhiweni kwezinto zokwakha ezisezingeni eliphezulu nezisebenza kahle kakhulu.
