Ukusetshenziswa kweHydroxypropyl Methyl Cellulose ku-Gypsum Mortar

(1), izici zei-hydroxypropyl methylcellulose ku-gypsum mortar:

1. Ukusebenza okuhle kokwakhiwa: kulula futhi kubushelelezi ukulenga, kungabunjwa ngesikhathi esisodwa, futhi kube ne-plasticity ngesikhathi esifanayo.

2. Ukuhambisana okuqinile: Ifanele zonke izinhlobo zezisekelo ze-gypsum, futhi inganciphisa isikhathi sokucwila se-gypsum, inciphise izinga lokunciphisa okomisa, futhi udonga akulula ukugoba nokuqhekeka.

3. Izinga elihle lokugcinwa kwamanzi: linganweba isikhathi sokusebenza kwesisekelo se-gypsum, lithuthukise ukumelana nokuqina kwesisekelo se-gypsum, likhulise amandla okubopha phakathi kwesisekelo se-gypsum nesendlalelo sesisekelo, ukusebenza okuhle kokubopha okumanzi, futhi kunciphise umlotha wokufika kanye nezinye izinkinga.

4. Thuthukisa izinga lokusabalala kwesisekelo se-gypsum: Uma kuqhathaniswa ne-hydroxypropyl methylcellulose ether efanayo, izinga lokusabalalisa lizokwenyuka kakhulu. Imikhiqizo ye-Hydroxypropyl methylcellulose ingakhuphula kakhulu izinga lokumboza, ingafaka izindawo eziningi, inganciphisa umfutho wabasebenzi, yonge izinto zokwakha, futhi ithuthukise izinzuzo zezomnotho.

5. Ukusebenza okuhle kwe-anti-sagging: lapho kulenga izingqimba eziwugqinsi, ukwakhiwa kwe-single-pass ngeke kugxumeke, futhi amaphasi angaphezu kwamabili, ngaphezu kuka-3cm, ngeke agxumeke lapho kulenga, futhi ipulasitiki ilungile.

6. Izinkambu zokufaka isicelo kanye nomthamo: i-gypsum eplastekayo ephansi elula, umthamo onconywayo ngu-2.5-3.5 kg/ton.

(2) Ukuhlolwa kokuhlolwa kwesicelo se-hydroxypropyl methylcellulose:

1. Ukuhlolwa kwamandla: Ngemva kokuhlolwa, i-hydroxypropyl methylcellulose esekelwe ku-gypsum inamandla amahle okubopha okuqinile namandla okucindezela.

2. Ukuhlola okunqanda ukuhlehla: Akukho ukuwohloka lapho ukwakhiwa kwephasi eyodwa kusetshenziswa izendlalelo eziwugqinsi, futhi akukho sag lapho kufakwa amaphasi angaphezu kwamabili (ngaphezulu kuka-3cm), futhi ipulasitiki ilungile.

3. Ukuhlolwa kokulenga odongeni: ilula futhi ibushelelezi lapho ilenga, futhi ingabunjwa ngesikhathi esisodwa. Indawo engaphezulu ithambile futhi ithambile, inokukhanya.

4. Ukuhlolwa kwesilinganiso sokusabalalisa: Izinga lokusabalala kwesisekelo se-gypsum libhekisela kumphumela otholwe ngokukala ukuminyana kwenqwaba emanzi yesisekelo se-gypsum. Ithani elilodwa lomkhiqizo osuselwe ku-gypsum wokwakhiwa kwendawo yodonga oluwugqinsi luka-10mm.

5. Ukuhlolwa kwezinga lokugcinwa kwamanzi: Izinga lokugcinwa kwamanzi elijwayelekile elijwayelekile le-GB/T28627-2012 “Plastering Gypsum”, izinga lokugcinwa kwamanzi le-gypsum eplastekayo eliphansi likhulu noma lilingana no-60%, kanye no-0.2% no-0.25% we-gypsum-based i-hydroxypropyl methylcellulose ingeziwe Inokusebenza okuhle kokugcinwa kwamanzi.
