Ama-admixtures asetshenziswa kakhulu ekwakheni udaka ngodaka lwe-HPMC

I-Hydroxypropyl methylcellulose (HPMC):

1. Ukwakheka kwamakhemikhali:
I-HPMCyi-ether engekho i-ether etholwa kusuka ku-polymer cellulose yemvelo ngokuguqulwa kwamakhemikhali.
Ihlanganiswe namaqembu we-methoxyl kanye ne-hydroxypropyl.

2. Imisebenzi nezinzuzo:
Ukugcinwa kwamanzi: I-HPMC ithuthukisa ukugcinwa kwamanzi ngodaka, okubaluleke kakhulu ukuthola i-hydration efanelekile yokwenza usimende nokwenza ngcono ukusebenza.
Ukuqina
I-Adhesion ethuthukisiwe: I-HPMC ithuthukisa izindawo zokunamathela zodaka, ukuvumela ukunamathela kangcono kuma-substrate ahlukahlukene.
Ukusebenza: Ngokulawula i-Rheology ye-Mortar Mix, i-HPMC ithuthukisa ukusebenza kwayo, okwenza kube lula ukufaka isicelo nokusakazeka.
Kuncishiswe i-sagging: kuyasiza ekunciphiseni ukubheja kanye nokwenza ngcono i-verticality yodaka olusetshenzisiwe, ikakhulukazi ezindaweni ezibheke mpo.
Ukuguquguquka okuthuthukisiwe: I-HPMC ingadlulisela ukuguquguquka kodaka, okuzuzisa kakhulu izinhlelo zokusebenza lapho kulindeleke khona ukunyakaza okuncane, njengokufakwa kwe-tile.
Ukumelana nokuqhekeka: Ngokuthuthukisa ubumbano kanye nokuguquguquka kodaka, i-HPMC isiza ekunciphiseni izehlakalo zokuqhekeka, ukuthuthukisa ukuqina kokuqina kwesakhiwo.

3. Izindawo zohlelo lokusebenza:
Ama-tile anamathela: I-HPMC isetshenziswa kabanzi kuma-tile anamathela ukuze uthuthukise ukunamathela, ukusebenziseka kanye nokugcinwa kwamanzi.
UMasoniry udaka: ekwakhiweni kwama-masonry ngodaka, i-HPMC inikela ekusebenzikeni okungcono, ukunamathela, kanye nokunciphiswa kwe-shrinkage.
Udaka oluphambanisa
Ama-compounds wokuzilinganisa: I-HPMC nayo isetshenziswa kumakhompiyutha okuzikhandla ukulawula ukugeleza kwezakhiwo futhi uthuthukise ukuqedwa komhlaba.

4. Imithamo kanye nokuhambisana:
Umthamo we-HPMC uyahlukahluka ngokuya ngezidingo ezithile nokwakhiwa kodaka.
Iyahambisana nezinye izengezo kanye nama-admixtures asetshenziswa kakhulu odongeni oluhlanganisiwe olomile, njengama-superplastimizer, ama-agents angenisa umoya, nokubeka ama-accelerator.

5. Izindinganiso zekhwalithi nokucatshangelwa:
I-HPMC esetshenziswe kwizicelo zokwakha kufanele ihambisane namazinga afanelekile kanye nemininingwane yokuqinisekisa ukuvumelana nokusebenza.
Ukulondolozwa okufanele nokusingathwa kubalulekile ukuze kugcinwe ukusebenza ngempumelelo kwe-HPMC, kufaka phakathi ukuvikelwa kumswakama nangokushisa okwedlulele.

6. Ukucatshangelwa Kwezemvelo Nezokuphepha:
I-HPMC ngokuvamile ithathwa njengephephile ukuze isetshenziswe kwizicelo zokwakha lapho isingathwa ngokuya ngemihlahlandlela enconyiwe.
Kuyinto engathandeki futhi ayibeki ubungozi obukhulu bemvelo lapho busetshenziswa njengoba kuhlosiwe.

I-Hydroxypropyl methylcellulose (HPMC)Ingabe ukuhlanganiswa okuguquguqukayo okusetshenziswa kakhulu ekwakhiweni kodaka okuxutshwe ngamakhono alo okuthuthukisa ukusebenza, ukunamathela, ukugcinwa kwamanzi, kanye nokusebenza okuphelele kwezinto zokwakha. Ukuhambisana kwalo ngezithasiselo ezahlukahlukene kanye nezicelo ezikhona kuzo zonke izimo zokwakha ezahlukahlukene zikwenza kube isithako esibalulekile emikhubeni yanamuhla yokwakha.
