I-HEC Ithuthukisa Kanjani Ukugcinwa Kwamanzi Ezinhlelweni Zesimende Eziqinile, Ezimelana Ne-Crack

Kungani Ukugcinwa Kwamanzi Kubalulekile Ezinhlelweni Zesimende

Izinto zikasimende ezifana nokhonkolo nodaka zithembele ekufakweni kwamanzi okulawulwayo ukuze kuthuthukiswe amandla. Ukulahlekelwa amanzi ngokushesha ngesikhathi sokwelashwa kuholela ku:

• Ukomisa Ngaphambi Kwesikhathi: Ibangela izibopho ezibuthakathaka kanye nokukhubazeka kwendawo.
• Ama-Shrinkage Cracks: Ukucindezeleka okuvela ekomisweni okungalingani kudala ubungozi besakhiwo.
• Ukuqina Okuncishisiwe: Ukumelana nokunciphisa isimo sezulu namandla okuthwala umthwalo.

I-Hydroxyethyl Cellulose (HEC), i-non-ionic cellulose ether, ibhekana nalezi zinselele ngokuthuthukisa ukugcinwa kwamanzi, ivumela ukugeleza kwamanzi kancane kanye nezakhiwo ezinamandla, ezimelana nokuqhekeka.

Isayensi Engemuva Kwamandla Okugcina Amanzi e-HEC

Isakhiwo samangqamuzana e-HEC—amaqembu e-hydrophilic hydroxyethyl axhunywe kumgogodla we-cellulose—sakha inethiwekhi ye-3D evalela amanzi. Izindlela eziyinhloko zifaka:

• I-Hydrogen Bonding: Ibopha ama-molecule wamanzi amahhala, inciphisa ukuhwamuka.
• Ukuthuthukisa i-Viscosity: Yakha i-colloid evikelayo ezungeze izinhlayiya zikasimende, igcine umswakama ngesikhathi sokwelashwa.
• Ukuqina kwe-pH: Isebenza ngokungaguquki ezindaweni zikasimende ezine-alkaline (pH 12–13).

Ucwaningo lubonisa ukuthi i-HEC ingathuthukisa ukugcinwa kwamanzi ngo15–30%uma kuqhathaniswa nezinhlelo ezingalashiwe, kunciphisa kakhulu ukuncipha kobudala.

I-HEC vs. Izithasiselo Zendabuko: Kungani Isebenza Kakhulu

Nakuba kusetshenziswa ezinye izindlela ezifana ne-methylcellulose (MC) noma i-guar gum, i-HEC inikeza izinzuzo eziyingqayizivele:

1. Ukuncibilika Kwamanzi Abandayo: Incibilika ngokushesha ngaphandle kokwelashwa kwangaphambili, yonga isikhathi namandla.
2. Ukubekezelela Usawoti: Izinzile ezixubeni ezinosawoti omningi (isb, ukhonkolo wasolwandle).
3. I-synergy nama-Superplasticizers: Igcina ukusebenza ngaphandle kokuyekethisa i-viscosity.

Izicelo Eziku-Crack-Resistant Systems

I-HEC ishintsha umdlalo we:

• Ukhonkolo Osebenza Kakhulu: Yehlisa ama-microcracks kumabhuloho nezakhiwo eziphakeme.
• Lungisa Izinsimbi: Ithuthukisa ukunamathela nokuphila isikhathi eside ezintweni zokuchibiyela.
• Izingubo zangaphansi zokuzilinganisa: Ivimbela ukomiswa ngaphambi kwesikhathi ukuze kuqedwe kahle.

Ucwaningo lwesigameko: Isivivinyo sango-2023 eJalimane sithole lokho kwengeza0.2% HECukulungisa udaka oluncishisiwe imifantu40%ngenkathi sithuthukisa amandla okucindezela wezinsuku ezingama-28 nge12%.

Ukusimama kanye Nezinzuzo Zezindleko

• I-Eco-Friendly: Isuselwe ku-cellulose evuselelekayo, engaboli, futhi engenabuthi.
• Udoti Owehlisiwe: Ukuqhekeka okumbalwa kusho izindleko eziphansi zokulungisa kanye nokushintshwa kwempahla.
• Ukuhambisana ne-LEED: Isekela izitifiketi zesakhiwo esiluhlaza ngokuthuthukisa ukuqina.
