Yuav ua li cas yog ib tug geopolymer qhob?

Txhua lub sij hawm, zaum ua kev ntsuam xyuas thiab thwmsim, uas tshawb xyuas cov sib tov, sib txuas ntuj thiab dag cov khoom xyaw. Xws li ib tug tandem tso cai mus muab tau cov ntaub ntawv nrog ib tug muaj kev kawm siab, vim lub ntsiab ntawm cov khoom cua keeb kwm tej tag nrho cov nuj nqis cov neeg hais tias xwm tau muab. Ntaub ntawv tau nyob rau hauv no txoj kev no yog hu ua puas los yog polymeric. Ib tug ntawm lawv - lub geopolymer ua vaj tse, uas yog qhov tseeb environmentally tus phooj ywg thiab kev nyab xeeb tsev ntaub. Lub prefix "geo" (nyob rau hauv Greek - "teb chaws") yog ib tug qhia hais tias cov khoom tshiab muaj tsuas ntuj cov khoom xyaw.

Lub pob zeb ua mix yog tsis ib yam dab tsi tshiab - nws twb tau lub npe hu rau cov txiv neej txij li thaum lub sij hawm ancient: thaum lub sij hawm tsim kho ntawm lub pyramids nyob rau hauv Iyi tebchaws los siv zoo xws li cov tsev ntaub. Tu siab, nws caij nyoog daim ntawv qhia tseem yog ib tug paub tsis meej rau niaj hnub tus txiv neej, tab sis, nrog cov kev taw qhia ntawm qhov tseeb technology, zaum twb tau los kwv yees muaj pes tsawg leeg, cov txheej txheem thiab tau yuav luag tib yam analog, geopolymer qhob yog dab tsi yog nyob rau hauv ancient sij hawm. Tab sis qhov no fact xwb ib tug keeb kwm thiab niaj hnub siv nws tsuas yog siv nyob rau hauv ib feem.

Hauj lwm txoj kev daws teeb meem

Ib tug ntawm cov tseem ceeb tshaj plaws thaj chaw ntawm lub tshiab qhob mix - nqi siab zog nyob rau hauv ib tug luv luv lub sij hawm kiag li ua kom tawv, nws yuav tsum tau tsuas yog ib lub lim tiam, whereas cov tsoos tshuaj rau qhov no yuav tsum tau raws nraim 4 lub sij hawm ntev.

Geopolymer qhob raws li Portland MAAs, muaj raws ntawm ob peb yam, tab sis muaj pes tsawg leeg nws txawv considerably. Tus tshiab cov kua muaj mas tshauv thiab slag - twj sib txawv ntawm cov lag luam. Yav tas los, xws pov tseg yog kiag li ua thiab tsuas tsim plua plav paug ib puag ncig. Ntawm cov hoob kawm, qhov teeb meem ntawm txoj kev cov ntaub ntawv yuav tsis daws tau qhov teeb meem tam sim ntawd, tab sis tshauv thiab slag yuav ib tug tseem ceeb qhov chaw ntawm raw cov ntaub ntawv rau lawv siv thiab ua.

Qhov zoo ntawm kev siv

Raws li kws txawj, cov geopolymer qhob - ib yam khoom nrog ib tug zoo kawg lawm yav tom ntej: tsis zoo li Portland MAAs nws yog siv nyob rau hauv qhov siv thiab ua khaub-ncaws nyias siv. Tab sis hais tias tsis yog tag nrho cov: nyob rau hauv lawv cov teplosohranyayuschim yam ntxwv ntawm tus tshiab qhob mix yog nyob deb superior rau lwm lub tsev ntaub ntawv, uas yog siv nyob rau hauv kev tsim kho ntawm vaj tse. Piv txwv li, cov phab ntsa thickness ntawm no geopolymer xwb 30 cm khaws thaum tshav kub kub li zoo li thwv cib, tab sis ib tug tuab ntawm 1.25 m.

Raws li, thov kev pab rau qhov kev siv ntawm ib tug tshiab tshuaj, koj yuav txuag tau nyiaj ntau ntau:

1. Koj muaj peev xwm txua vaj tse muaj tsawg cov ntaub ntawv.
