Kua iav - yog dab tsi? Kua iav dej qab zib

Sawv daws yeej paub dab tsi ib qho iav. Nws tshwm nyob rau hauv Egypt txog 5,000 xyoo dhau los. Thiab ces muaj yog dej iav. Yuav ua li cas yog nws? Tsis yog, nws tsis yog ib yam dab tsi zoo heev. Qhov no aqueous tov uas tau npaj los ntawm sodium silicate.

tag nrho

Silicate lo los yog dej iav, - ib tug tov ntawm dej thiab silicate ntsev. Nyob rau hauv kev npaj ntawm cov muaj pes tsawg leeg siv cov khoom xyaw tib uas yog siv rau zus tau tej iav khoom.

Qhuav yees ntau. Ntau nrov - nws yog lub feem ntawm kev daws rau ntaub ntawv uas muaj silica nyob rau hauv qhov kub. Ob txhais Embodiment - fusing xuab zeb thiab cov dej.

Raws li hais hauv daim ntawv thov, siv sib txawv thiab xov ua hauj lwm yog tsis tau tsis muaj no muaj pes tsawg leeg. Yog tsis muaj zoo dua cov ntaub ntawv uas rau waterproofing tshaj kua iav. Yuav ua li cas yog nws lub npe hu rau ib ntev lub sij hawm, rau lub hom phiaj ntawm ib yam dab tsi zoo dua yog tsis tau tsim. Kev siv cov no nplaum heev tsub kom lub neej ntawm lub tsev.

Silicate lo ua rau lub hauv paus ntawm sodium, potassium los yog lithium, txawm hais tias tus tom kawg yog siv heev tsis tshua muaj. Poov tshuaj yog siv nyob rau hauv ntau lub teb, thiab nws muaj zoo heev kev yam ntxwv thiab cov khoom. Yog hais tias koj muab qhov no piv nplaum thiab sodium dej iav, thawj qauv muaj ib tug xoob me qauv. Stitches ua nrog no lo tsis txawv stability.

Thiab poov tshuaj, sodium thiab adhesives yuav siv tau nyob rau hauv ntau qhov chaw, tab sis cov muaj pes tsawg leeg rau ntawm lub hauv paus ntawm poov tshuaj tshwm sim ntau npaum li cas tsawg zaus. Qhov no yog hais tias nws tus nqi yog heev siab heev. Yog li ntawd feem ntau nws yog hloov nrog sodium adhesives.

qauv

Nyob rau hauv tshuaj nroj tsuag rau zus tau tej cov universal uas siv sulfuric anhydrite, hlau oxide thiab txhuas silicate modulus, sodium thiab calcium oxide, pob zeb ntais dioxide. Sodium waterglass thiab poov tshuaj yuav tsum muaj li ntawm sodium thiab calcium oxide, tab sis nyob rau hauv me me compositions. Yog li, lub iav muaj ib tug 9% sodium, sodium thiab calcium - tsuas yog 0.2%.

kev yam ntxwv

Qhov no iav raws li GOST 13078-81. Cov kev ceev uas cov ntaub ntawv uas yuav qhuav nyob rau yuav ua li cas thiab nyob qhov twg nws yog thov. Yog hais tias lub khob yog siv nyob rau hauv cov ntshiab daim ntawv no, nws yog qhuav rau 10 feeb. Muaj pes tsawg leeg ntawm lub mixtures thaum lub sij hawm solidification yuav siv sij hawm 2 teev.

Cov kev ceev ntawm lub khob yog li 1,45 g / cm ^3. Txee lub neej - 2 xyoo. Kev Lub ntiajteb txawj nqus - 1,45. Yuav kom yaj silicate kua nplaum, nws yuav tsum tau rhuab mus rau 1088 degrees.

ntau lawm

Cov tsim txoj kev ntawm cov kua iav es nyuab, yog li ua cov ntaub ntawv uas nyob rau hauv lub tshuaj ua lag luam. Thawj kauj ruam yog av quartz xuab zeb, thiab ces tov nrog sodium carbonate, poov tshuaj carbonate, sodium los yog poov tshuaj sulphate.

Ces nws tag nrho fused rau hauv ib lub tsev ingot. Rau lub hom phiaj no, autoclaves. Tom qab melting lub resulting loj yuav tsum tau yaj. Nyob rau hauv rooj plaub no tus kub yuav tsum txog 170 degrees. Qhov no tus txheej txheem yog heev ntev thiab yuav siv sij hawm txog 7 teev.

daim ntawv thov

Cov kev siv kev lag luam tau ntev to taub thiab muaj peev xwm nyob tau mus thov cov kua iav. Yuav ua li cas nws yog, ntawm chav kawm, tab sis cov kua nplaum yog siv? Nws yog vim lub ntsiab khoom, tab sis, theej ib tug siab nplaum zog, qhov no cov ntaub ntawv uas tau ua ib tug ntawm lub Cheebtsam rau ib tug ntau yam ntawm mortars.

Sodium thiab poov tshuaj iav muaj tseem sib txawv qauv, thiab nws lub sij lub Scope ntawm lawv cov kev siv. Cov yav tas yog resistant rau tshuaj thiab weathering. Feem ntau qhov no cov ntaub ntawv uas yog siv raws li ib tug ntawm cov khoom xyaw rau zus tau tej cov kev tiv thaiv cov xim tsev.

Dej qab zib iav yuav ua tau kom cov nplaum zoo. Cov khoom ua hauj lwm zoo nrog mineral tshuaj. Lug siv sodium silicate cov nplaum rau cov waterproofing cov me nyuam yaus. Tsis tas li ntawd nyob rau hauv nws lub hauv paus yog npaj antiseptic thiab hluav taws retardant sib tov. Tab sis muaj lwm yam khoom uas muaj dej iav.

Yuav ua li cas yog nws, lub npe hu xwb los kev builders. Txawm li cas los, yog tsis muaj txoj kev zoo rau zus tau tej cov thermal rwb thaiv tsev cov ntaub ntawv. Siv ntawm no cov ntaub ntawv uas muaj peev xwm mas heev kub.

Qhov no cov ntaub ntawv uas yog yuav luag tag txawm rau tib neeg. Txawm li cas los, koj yuav tsum mus ua hauj lwm nrog nws heev kom zoo zoo: tag nrho cov txhaum ntawm alkali - ib qho ntawm lub Cheebtsam. Nws yog qhov zoo tshaj plaws los mus siv cov hnab looj tes thaum kov.

Kua iav: tus nqi yog tsawg tsawg, nyob rau qhov siab ntawm cov kev tshwm sim

Tsis tsuas yog vim hais tias ntawm lub high school kawm, cov khoom no twb tau thov nyob rau hauv kev tsim kho. Tsis zoo li lwm yam zoo xws ntaub ntawv, iav nqi yog tsawg heev (200 rubles. 5 kg). Yog li ntawd, nws siv raws li ib tug tivthaiv nyob rau hauv pob zeb ua kev daws teeb meem. Nws yuav them rau cov nqi ho txhim kho yam ntxwv zog thiab ya raws kuj. Silicate lo yog tau maximize sau txawm qhov tsawg tshaj plaws tej kab nrib pleb los yog pob.

Nrog rau tag nrho cov zoo muaj yog ib tug me me disadvantage - ib tug ceev ceev curing ceev. Tej zaum nws tsis yog tswv yim heev. Yog li ntawd, feem ntau ib tug silicate nplaum nto pawg impregnated. Thiab yog hais tias nws yog ces pleev xim rau los yog plastered, ces cov kua tsis yog tsim nyog los siv iav.

Tsis tsuas yog rau kev tsim kho ntawm

Qhov no cov ntaub ntawv uas yog nrov tsis tsuas nyob rau hauv kev ua lag luam. Muaj ntau tsav tsheb siv kua iav rau cov tsheb. Kom txog rau thaum nyuam qhuav, ntawm cov tshuaj rau hauv lub cev xwb nws yog ciab, thiab hnub no yog heev nrov tshwj xeeb tej hub pes tsawg leeg los yog cim nanocoating.

Ceramic txheej kua iav cev muab siab gloss, siab water- thiab av-pleev cov tshuaj zog, siab kuj tshav, tiv thaiv los ntawm khawb thiab tshuaj. Koj tau yooj yim yuav kua iav - nws tus nqi yog tsawg heev.

Txawm li cas los nanokosmetika rau nws cov hauv paus yuav tsum tau saib qhov muag. Tsis tas li ntawd, muaj ntau yam teeb meem nrog rau daim ntawv thov ntawm cov tebchaw nyob rau hauv lub cev.

daim ntawv thov technology

Cov ua ntawm lub tsheb hu ua tej hub polishing. Nws yog tib yam rau tag nrho cov nanopreparations. Thawj kauj ruam yog los ntxuav lub tsheb kom huv si. Ces ua degreasing ntawm lub cev tag nrho saum npoo av. Ua li no, xaiv tau cawm cov tshuaj. Ntxiv mus, polishing yog ua kom tshem tawm cov laus remnants polishing pastes thiab ntau yam inclusions. Ces tshem tawm cov nti thiab polished mus rau ib tug ci dua. Ntxiv thov waterglass. Yuav ua li cas yog nws ntev paub, tiam sis pib siv tau tsuas yog ib ob peb xyoos dhau los. Nws yuav tsum tau ua ntawv thov los ntawm 3 mus rau 10 khaubncaws sab nraud povtseg. Ces lub cev yog qhuav rau 8 teev. Yog hais tias muaj tej yam kev txawj ntse uas yuav tau mus thov mus rau lub muaj pes tsawg leeg ntawm lawv tus kheej txhais tes. Tab sis ua tib yam li nyob rau hauv lub srt yuav raug nqi ib tug nqi siab.

Yuav ua li cas ntev li cas lub kev pab them nqi?

Kua iav rau lub tsheb raws li cov chaw tsim tshuaj paus yuav tsum tau muaj nyob rau hauv lub cev ntawm 3 xyoo. Txawm li cas los, nws yog pom zoo kom hloov tag nrho cov ntau ntau. Nws yog zoo dua rau ua 1 lub sij hawm rau ib lub xyoo, yog hais tias tus tshuab yog siv txhua txhua hnub.

Yuav ua li cas ntxuav koj lub tsheb?

Thawj lub sij hawm lub tsheb ntxuav yog tsis tsim nyog, vim hais tias tseem muaj kev tsim tsa ntawm high-tech kev tiv thaiv txheej. Manufacturers ntawm cov tebchaw hais tswv yim los txhob ntxuav rau 3 lub lis piam. Ces, nyob rau hauv rov qab yuav muaj me ntsis av, thiab nws yuav ua tau txaus cia li mus yaug.

Xyuas

Nanoceramics rau cov tsheb ua tau xwb. Tag nrho cov neeg uas tau sim rau cov dej iav, tsuas sau zoo xyuas.

Txheej yog ib qhov nyuaj heev, nws tsis yog txawm ib tug ntsia thawv mus kos. Dej kuj tsis nyob twj ywm nyob rau hauv lub cev. Ciab xws li ib cov nyhuv tsis.

Siv cov kev faib tshwj xeeb kuj zoo txog cov khoom. Nws tus yam ntxwv, tus nqi pheej yig pub rau waterproofing tej hauj lwm sai heev.
