Yintoni i-self-leveling gypsum mortar?

Udaka lwegypsum oluzilinganisayo, olukwabizwa ngokuba yi-self-leveling gypsum underlayment okanye i-self-leveling gypsum screed, luhlobo lwemathiriyeli yomgangatho eyilelwe ukwenza umgangatho ongaphezulu phezu komgangatho ongalinganiyo. Yenziwe ngomxube we-gypsum powder, i-aggregates, kunye neentlobo ezahlukeneyo zokudibanisa ezibonelela ngodaka kunye neempawu zalo zokuzilinganisa.

Udaka lwegypsum oluzilinganisayo luqhele ukusetyenziswa kwizicelo zangaphakathi, ezinjengendawo yokuhlala kunye nezakhiwo zorhwebo, apho lugalelwa ngaphezulu kwekhonkrithi, iinkuni, okanye ezinye iintlobo zemigangatho engaphantsi. Lukhetho oludumileyo lofakelo lomgangatho ngenxa yokusebenziseka lula, isantya sokufakela, kunye nokukwazi ukwenza umphezulu ogudileyo kunye nomgangatho olungele ukufakwa komgangatho ongaphezulu.

Ukuqulunqwa kwe-Self-Leveling Gypsum Mortar

Udaka lwegypsum oluzilinganisayo lwenziwe ngokudityaniswa komgubo wegypsum, iaggregates, kunye nezongezo ezahlukeneyo ezibonelela ngodaka kunye neempawu zalo zokuzilinganisa. I-powder ye-gypsum isebenza njenge-binder, ngelixa i-aggregates, ngokuqhelekileyo isanti okanye i-perlite, ibonelela ngesakhiwo kunye nokuzinza kumdaka. Izongezo ezisetyenziswa kumdaka we-gypsum wokuzilinganisa zinokuhluka, kodwa zibandakanya:

1. I-Superplasticizers: Ezi zizongezo zekhemikhali ezisetyenziselwa ukunyusa ukuhamba kunye nokusebenza komdaka, okuvumela ukuba uzenzele kwaye uzalise iindawo eziphantsi.
2. I-Retarders: Ezi zizongezo ezicotha ixesha lokumisela udaka, zinika ixesha elingakumbi lokuhamba kunye nenqanaba ngaphambi kokuba liqine.
3. Ukomelezwa kweFayibha: Ezinye iintsimbi zegypsum ezizilinganisa ngokwazo zinokuqulatha ifayibha yokuqinisa, enokuphucula amandla kunye nokuqina kodaka.
4. Ezinye izongezo: Ezinye izongezo zingongezwa ukuphucula ukunyanzeliswa kwamanzi kumdaka, ukucutheka, okanye ukuncamathela kwi-subfloor.

Ukusetyenziswa kwe-Self-Leveling Gypsum Mortar

Ukusetyenziswa kodaka lwegypsum oluzilinganisayo lubandakanya amanyathelo aliqela. Okokuqala, i-subfloor kufuneka ihlambuluke ngokucokisekileyo kwaye ilungiswe ukuqinisekisa ukunamathela ngokufanelekileyo kodaka. Naziphi na izinto ezixeliweyo, ezinje ngobutyobo, uthuli, okanye izinto ezincamathelayo ezindala, kufuneka zisuswe.
