Lub keeb kwm ntawm tshwm sim

Cementing ntaub ntawv pib yuav tsum tau siv nyob rau hauv ancient sij hawm. Thawj zaug nws yog cov nqaij nyoos av nplaum. Vim nws yooj yim rau tau thiab disseminating nws thov qhov txhia chaw. Tab sis vim hais tias ntawm cov uas qaug zog viscosity thiab stability ntawm av nplaum muab txoj kev ua cua sov rau kho cov ntaub ntawv.

Nyob rau hauv Egypt thawj zoo tsim kho cov ntaub ntawv twb npaj. Qhov no txiv qaub thiab plaster. Lawv muaj peev xwm tawv nyob rau hauv cov huab cua, thiab li tau tau lug siv. Cov tsev ntaub ntawv raws li cov uas yuav tsum tau, twb tsis tau pib los tsim navigation. Nws los ua tsim nyog ib tug tshiab tshuaj uas yuav tiv thaiv qhov kev txiav txim ntawm cov dej.

Nyob rau hauv lub XVIII xyoo pua, nws yog invented khoom - romantsement. Nws yog ib yam khoom uas yuav tawv rau hauv cov dej thiab nyob rau hauv cov huab cua. Tab sis lub zog txoj kev loj hlob ntawm lub lag luam yuav tsum tau zoo dua cov ntaub ntawv thiab kev ruaj zog. Nyob rau hauv lub XIX xyoo pua nws twb yees ua ib tug tshiab tshuaj rau cov thwj toob. Nws yog hu ua Portland MAAs. Qhov no cov ntaub ntawv uas yog siv los mus hnub no. Nrog rau txoj kev loj hlob ntawm cov tib neeg mus rau lub phau ntawv tswj tshiab xav tau. Rau txhua kev lag luam siv nws tus kheej hom, uas muaj cov kev tsim nyog zog.

qauv

Maas - yog qhov tseem ceeb feem ntawm qhov kev siv kev lag luam. Lub ntsiab Cheebtsam nyob rau hauv nws yog av nplaum thiab limestone. Lawv sib xyaw ua ke thiab raug los ua cua sov kev kho mob. Ces tus uas ua loj yog as mus rau ib tug hmoov zoo. Grey zoo sib tov - qhov no yog qhov xis mas. Thaum tov nrog dej, lub qhov ceeb thawj yuav nws thiaj li ua zoo li ib lub pob zeb. Lub ntsiab feature yog lub peev xwm rau tawv nyob rau hauv cov huab cua thiab tiv ya raws.

Kev npaj ntawm grout

Yuav kom lub tsev loj yog tsim nyog zoo ntawm qhov yuav tsum muaj tsawg kawg yog 25% kua. Hloov cov piv nyob rau hauv cov kev taw qhia tau nyob rau hauv qis kawm thaj chaw ntawm cov tshuaj raws li zoo raws li nws zoo. Qaug dab peg tom qab 60 feeb tom qab tas li ntawd ntawm dej, thiab tom qab 12 teev, lub sib tov loses nws elasticity. Tag nrho cov nyob rau ntawm huab cua kub. Lub siab dua nws yog, tus ceev cov tawv loj.

Rau cov tshuaj yuav tsum tau cov xuab zeb rau hauv uas xis mas yog ntxiv. Cov uas ua sib tov yog meej tov thiab poured dej. Nyob rau hauv lub chaw ua hauj lwm ua cov tshuaj yuav ua tau ib tug pa los yog enriched. Tus thawj muaj cov proportions ntawm 1: 5, thiab lub thib ob - 1: 2.

Hom thiab xis mas ntau lawm

Thaum lub caij, nws ua ib tug ntau ntawm cov ntau ntau yam ntawm phau ntawv. Txhua yus muaj los ntawm nws tus kheej degree ntawm hardness, uas yog qhia nyob rau hauv lub cim.

Lub ntsiab yam yog:

• Portland MAAs (txiv qaub). Nws yog tus founder ntawm tag nrho cov hom. Hom twg yog siv raws li ib tug hauv paus. Qhov sib txawv yog kom muaj nuj nqis thiab muaj pes tsawg leeg ntawm lub additives uas impart ntshaw zog xis mas. Lub hmoov nws tus kheej muaj ib tug grey-ntsuab xim. Thaum muab kua nws hardens thiab prochneet. Tsis siv ntawm nws tus kheej nyob rau hauv kev tsim kho, thiab yog raws li ib lub hauv paus rau lub creation ntawm puas cov ntaub ntawv.

• Aluminous. Nws possesses siab ua si tus nqi chaw (45 feeb) thiab solidification (full tshwm sim tsis pub dhau 10 xuaj moos). Tsis tas li ntawd yus feature yog lub nce kuj mus ya raws.
• Acid. Tsim los ntawm nws silica xuab zeb thiab sodium silicofluoride. Dej qab zib yog ntxiv los npaj ib tug tov waterglass. Qhov kom zoo dua ntawm xws MAAs - kuj mus acids. Disadvantage - ib tug me me lub neej.
• Xim. Tsim los ntawm nws Portland MAAs thiab xim tshuaj. Qhov txawv tsuas yog siv rau cov hniav hom phiaj.

Maas ntau lawm yog muaj li ntawm plaub theem:

• Extraction ntawm raw cov ntaub ntawv thiab nws cov kev npaj.
• Tua thiab clinker ntau lawm.
• Sib Tsoo mus rau ib tug hmoov zoo.
• Additive tsim nyog impurity.

Txoj kev ntawm zus tau tej cov MAAs

Muaj 3 txoj kev, uas nyob ntawm seb lub raw khoom npaj rau thermal kho mob:

• Ntub. Nrog rau qhov no txoj kev, tag nrho cov theem ntawm MAAs ntau lawm yuav tsum tau kom muaj nuj nqis ntawm cov kua yog tam sim no. Nws yog siv nyob rau hauv lub sij hawm uas lub ntsiab Cheebtsam tsis muaj peev xwm koom tau rau hauv tus txheej txheem tsis muaj kev siv ntawm cov dej. Nws yog chalk nrog ib tug high school cov dej cov ntsiab lus, yas av nplaum los yog limestone.

• Qhuav. Tag nrho cov MAAs raug cov kauj ruam kuaj nrog cov ntaub ntawv uas muaj ib tug tsawg kawg nkaus kom muaj nuj nqis ntawm cov dej.
• Chav. Maas ntau lawm muaj xws li ob leeg ntub thiab qhuav txoj kev. Initial MAAs tov yog tsim nrog dej, thiab ces nws twb lim tshaj plaws tshwj xeeb cov khoom.

qhob

Qhov no tsev ntaub, uas yog tsim los ntawm nws ib tug xis mas, ib tug tub lim, thiab kua additives yuav tsum tau.
