Ifomula kunye nenkqubo yodaka olutsha lwegypsum

Ukudala udaka olutsha lwegypsum kubandakanya ukuqwalaselwa ngenyameko kweempawu ezifunwayo kunye neemfuno zokusebenza. Nantsi ifomula ngokubanzi kunye nenkqubo yokuphuhlisa udaka lwegypsum olusisiseko:

Izithako:

1. I-Gypsum: I-Gypsum yi-binder ephambili kwi-mortar kwaye inikezela ukunamathela okufunekayo kunye namandla. Ngokuqhelekileyo iza ngohlobo lwe-gypsum plaster okanye i-gypsum powder.
2. I-aggregates: Ii-aggregates ezifana nesanti okanye i-perlite zisenokongezwa ukuphucula ukusebenza, ukuxinana kwesambuku, kunye neempawu zomatshini wodaka.
3. Amanzi: Amanzi abalulekile ekufakeni amanzi kwigypsum kunye nokwenza intlama esebenzayo.

izongezo (Ngokuzikhethela):

1. IiRetarders: IiRetarders zingongezwa ukulawula ixesha lokumisela udaka, ukuvumela ixesha elide lokusebenza.
2. Izilungisi: Iimodyuli ezahlukeneyo ezifana ne-cellulose ethers, iipolima, okanye i-air-entraining agents zinokudityaniswa ukuphucula iimpawu ezithile ezifana nokusebenza, ugcino lwamanzi, okanye ukuqina.
3. I-Accelerators: Ii-accelerators zinokuqukwa ukukhawulezisa ukusetwa kunye nenkqubo yokunyanga, iluncedo kwimozulu ebandayo okanye usetyenziso oluthatha ixesha.
4. Izigcwalisi: Izigcwalisi ezifana ne-lightweight aggregates okanye i-microspheres zingasetyenziselwa ukunciphisa ubuninzi kunye nokuphucula iimpawu ze-thermal okanye i-acoustic insulation.

Inkqubo:

1. Ukuxuba:
   • Qala ngokulinganisa kwangaphambili izixa ezifunekayo zegypsum, i-aggregates, kunye nezongezelelo ngokwendlela efunwa ngayo.
   • Hlanganisa izithako ezomileyo (i-gypsum, i-aggregates, fillers) kwisitya sokuxuba okanye umxube kwaye udibanise ngokucokisekileyo kude kube yi-homogeneous.
2. Ukongeza Amanzi:
   • Yongeza kancinci amanzi kumxube owomileyo ngelixa udibanisa ngokuqhubekayo de kube i-paste egudileyo, esebenzayo yenziwe.
   • Umlinganiselo wamanzi ukuya kwi-gypsum kufuneka ulawulwe ngokucophelela ukuze ufezekise ukuhambelana okufunayo kunye nexesha lokubeka.
3. Ukubandakanya izongezo:
   • Ukuba usebenzisa izongezo ezinje ngeretarders, accelerators, okanye modifiers, zongeze kumxube ngokwemiyalelo yomenzi.
   • Xuba udaka ngokucokisekileyo ukuqinisekisa ukuhanjiswa okufanayo kwezongezo kunye nokusebenza okuhambelanayo.
4. Uvavanyo kunye noLungiso:
   • Yenza iimvavanyo kudaka olusanda kulungiswa ukuvavanya iipropathi ezinjengokusebenza, ixesha lokubeka, uphuhliso lwamandla, kunye nokuncamathela.
   • Lungisa uqulunqo njengoko kuyimfuneko ngokusekelwe kwiziphumo zovavanyo kunye neendlela zokusebenza ezifunekayo.
5. Isicelo:
   • Gcoba i-gypsum mortar kwi-substrate usebenzisa iindlela ezifanelekileyo ezifana nokubhuqa, ukutshiza, okanye ukugalela.
   • Qinisekisa ukulungiswa okufanelekileyo komphezulu kunye nokuhambelana kwe-substrate ukunamathela ngokufanelekileyo kunye nokusebenza.
6. Ukunyanga:
   • Vumela udaka ukuba lunyange kwaye lubekwe ngokwexesha elibekiweyo, kuthathelwa ingqalelo iimeko zokusingqongileyo ezifana nobushushu kunye nokufuma.
   • Ukubeka iliso kwinkqubo yokunyanga kwaye ukhusele udaka ekomisweni kwangaphambi kwexesha okanye ukuvezwa kweemeko ezimbi.
7. Ulawulo lwemeko:
   • Yenza uvavanyo lolawulo lomgangatho kudaka olunyangisiweyo ukuvavanya iipropathi ezinje ngamandla, ukuqina, kunye nokuzinza komda.
   • Yenza naluphi na uhlengahlengiso oluyimfuneko ekuqulunqweni okanye kwiindlela zokusetyenziswa ngokusekelwe kwiziphumo zokulawula umgangatho.

Ngokulandela le fomyula kunye nenkqubo, unokuphuhlisa i-gypsum mortar entsha elungiselelwe iimfuno ezithile zeprojekthi, ukuqinisekisa ukusebenza kakuhle kunye nokuqina. Kubalulekile ukwenza uvavanyo olucokisekileyo kunye nolawulo lomgangatho kuyo yonke inkqubo yophuhliso ukufezekisa iziphumo ezingaguqukiyo kunye nokuhlangabezana nemigangatho yoshishino.
