1. Isayensi Yezinto Ezibalulekile kanye Nezindlela Zokusebenza
1.1 Incazelo kanye Nokuhlelwa Kwezinhlanganisela Ezingasindi
(I-Lightweight Concrete Admixtures)
Izithako zikakhonkolo ezingasindi zingamakhemikhali akhethekile noma izithasiselo zomzimba eziklanyelwe ukunciphisa ukuminyana kwezinhlelo zikasimende ngenkathi zilondoloza noma zithuthukisa ukusebenza kahle kwesakhiwo nokusebenza kahle..
Ngokungafani nama-aggregate omdabu, lezi zixube zethula i-porosity elawulwayo noma zihlanganisa izigaba zokuminyana okuphansi ku-matrix kakhonkolo., okuholela ezisindweni zedivayisi ngokuvamile ezisukela ku 800 ku 1800 kg/m ZIMBILI, kuqhathaniswa nama-2300– 2500 kg/m ³ ngokhonkolo ojwayelekile.
Ahlukaniswe kabanzi abe izinhlobo ezimbili: amagwebu amakhemikhali kanye nokuhlanganiswa kwesisindo sokukhanya okwakhiwe kusengaphambili.
Abamele amagwebu amakhemikhali bakha kahle, izikhala zomoya ezinzile ngokuthulwa kwe-in-situ gas– ngokuvamile ngokusebenzisa impushana ye-aluminium kukhonkolo owenziwe nge-autoclaved aerated (I-AAC) noma i-hydrogen peroxide ene-catalysts– kuyilapho ukufakwa okwenziwe kusengaphambili kuhlanganisa i-polystyrene enwetshiwe (EPS) okusanhlamvu, i-perlite, i-vermiculite, kanye ne-ceramic noma i-polymer microspheres engenalutho.
Okuhlukile okuthuthukisiwe nakho kufaka phakathi i-silica evunyelekayo ene-nanostructured, ama-aerogels, kanye nokuqongelelwa kabusha kwesisindo sokukhanya okuvela emikhiqizweni yezimboni efana nengilazi enwetshiwe noma i-slag.
Ukukhethwa kwe-admixture kuncike ekufakweni kwe-thermal okudingekayo, ukuqina, ukumelana nomlilo, kanye nokusebenza, ukubenza basebenze ngezindlela ezihlukahlukene ezidingweni ezahlukene zokwakha.
1.2 Isakhiwo Sezimbotshana kanye Nobudlelwano Bokuminyana-Impahla
Ukusebenza kahle kukakhonkolo wesisindo esilula kulawulwa yi-morphology, ukusatshalaliswa kosayizi, kanye nokuxhumana kwama-pores okwethulwa yi-admixture.
Amasistimu alungile afaka ukusabalala ngokulinganayo, izimbotshana zamaseli avaliwe ezinosayizi phakathi 50 futhi 500 ama-micrometer, okunciphisa ukumuncwa kwamanzi kanye ne-thermal conductivity ngenkathi kusizakala ngokugcwele ekusebenzeni kokufakwa.
Izimbotshana ezivulekile noma ezixhumene, ngenkathi kuncipha ukuminyana, ingalimaza amandla nokuqina ngokusiza ngokufinyelela ubumanzi kanye nomonakalo wokuqandisa.
Izingxube ezizinza kahle, amabhamuza ahlukene– njengama-protein-based noma ama-surfactants okwenziwa kukhonkolo wegwebu– qinisa kokubili ukuqina komshini nokusebenza kahle kokushisa.
Ubudlelwano obuphambene phakathi kokuminyana kanye nokuqina okucindezelayo kusungulwe kahle; nokho, ukwakheka kwesimanje kwe-admixture kunciphisa lokhu kuhwebelana ngokusebenzisa ukuminyana kwe-matrix, ukuqinisa i-fiber, kanye nemithi yokwelapha elungiselelwe.

Ngokwesibonelo, okuhlanganisa i-silica fume noma umlotha ondizayo kanye nokumela amagwebu kushuna kahle uhlaka lwembotshana futhi kuthuthukise ukunamathisela okukhonkolo, ukunika amandla ukhonkolo ongasindi onamandla aphezulu (kuya ku 40 I-MPa) ngezicelo zezakhiwo.
2. Uhlobo Lwenhlanganisela Eyinhloko Nezindima Zazo Zobunjiniyela
2.1 Ama-brokers Amagwebu kanye nezixazululo zokungenisa umoya
Abamele amaprotheni-based and synthetic frothing bayisisekelo sokukhiqiza ukhonkolo wegwebu, ukudala amabhamuza omoya avikelekile ahlanganiswe ngomshini ku-slurry kakhonkolo.
Amagwebu amaprotheni anempilo, etholakala emithonjeni yezilwane noma yemifino, zinikeza ukuphepha okuphezulu kwegwebu futhi zilungele izinhlelo zokusebenza eziphansi (
I-Cabr-Concrete ingumphakeli we-Concrete Admixture ene-over 12 Iminyaka yokuhlangenwe nakho kwe-nano-building energy ukongiwa kanye nokuthuthukiswa kwe-nanotechnology. Yamukela inkokhelo ngekhadi lesikweletu, T/T, I-West Union ne-Paypal. I-TRUNNO izothumela izimpahla kumakhasimende aphesheya kwezilwandle nge-FedEx, I-DHL, ngomoya, noma ngolwandle. Uma ufuna ikhwalithi ephezulu ye-Concrete Admixture, sicela ukhululeke ukuxhumana nathi futhi uthumele uphenyo.
