I-Tile Adhesive Construction
Kunezinhlobo ezimbili zezinto ezisetshenziswayo ezisetshenziselwa ukubeka amathayili: enye inamathela ngamathayi, kanti enye iyinhlangano yokunamathisela yokunamathisela yokunamathisela, engabizwa nangokubizwa ngokuthi yi-glue emuva ye-tile emuva. I-Tile Adhesive ngokwayo yi-emulsion-efana ne-auxisissiesdiate ebalulekile, ngakho-ke silusebenzisa kanjani i-tile adhesive elungile ...Funda kabanzi -
Ungayisebenzisa kanjani i-tile anamathela kahle
Hlanza umhlane wethayela kuqala. Uma amabala, ungqimba oluntantayo kanye ne-dephual deder edelela ngemuva kwamathayili ahlanzwa, kulula ukuqoqa futhi wehluleke ukwakha ifilimu ngemuva kokuthi kusetshenziswe i-adhesive ngemuva kokufakwa okunamathela. Isikhumbuzi esikhethekile, amathayili ahlanzekile angapendwa kuphela ngokunamathela ngemuva kokuba sebe ...Funda kabanzi -
I-Glue Tlue, i-Tile Adhesive, I-Tlue Emuva Yasemuva, Silly Futhi Acaci
Manje lapho sihlobisa futhi sibeka amathayili ekhaya, sihlala sihlangabezana nesimo esinjalo: I-Master Bricklayer ebeka ama-tile iyasibuza: Ngabe usebenzisa ukusekela okunamathela ekhaya lakho? Abanye baphinde babuza ukuthi bayisebenzise yini ukunamathela kwe-tile? Kulinganiselwa ukuthi abangane abaningi bazodideka ....Funda kabanzi -
Izinkinga zakudala nge-hydroxypropylylylylylyls cellulose
1. Yiluphi uhlelo lokusebenza oluphambili lwe-hydroxypropyllll methylcellulose (HPMC)? I-HPMC isetshenziswa kabanzi ezintweni zokwakha, ukumboza, ama-desin okwenziwa, ama-ceramics, umuthi, ukudla, izindwangu, amazweli, ugwayi kanye nezinye izimboni. I-HPMC ingahlukaniswa iba ibanga lokwakha, ibanga lokudla ...Funda kabanzi -
Uyini umehluko phakathi kwe-HPMC ne-MC
I-MC yi-methyl cellulose, etholakala ngokuphatha ukotini ocwengekile nge-alkali, usebenzisa i-methyl chloride njenge-ejenti yokuphelisa, nokwenza i-cellulose ether ngochungechunge lokuphendula. Ngokuvamile, izinga lokufakwa esikhundleni ngu-1.6 ~ 2.0, kanye ne-solubity futhi kwehlukile ngama-degree ahlukene ...Funda kabanzi -
Izici ezithinta ukukhiqizwa kwento ye-HPMC
1. I-Viscosity ilawulwa kakhulu i-Hydroxyproppropyll methylcellulose ayikwazi ukukhiqiza i-cellulose ephezulu kakhulu ngokuvuselela nokubuyisela i-nitrogen. Kodwa-ke, uma ithuluzi lokulinganisa le-avector oxygen lingafakwa ku-kettle, ukukhiqizwa kwe-viscosity kungalawulwa ngobuciko. 2. Ukusetshenziswa ...Funda kabanzi -
