Txhua txoj haujlwm tsim kho thiab kho dua tshiab yog ua los ntawm kev siv ntau yam ntaub ntawv. Gypsum thiab alabaster yog ntawm lawv. Lawv zoo ib yam rau ib leeg, ob sab nrauv thiab hauv qhov dav, thiab lawv feem ntau tsis meej pem. Hauv kab lus peb yuav tham txog txhua yam ntawm cov ntaub ntawv no, txiav txim siab lawv cov yam ntxwv zoo, tshuaj xyuas seb lawv sib txawv li cas, thiab qhov twg yog qhov zoo dua los xaiv.
Dab tsi khov dua?
Ua ntej peb pib xam seb ob yam tshuaj no txawv li cas thiab lawv zoo li cas, cia peb txheeb xyuas seb lawv txhua tus yog dab tsi.
Gypsum belongs rau qhuav tsev sib tov, lub hauv paus ntawm uas yog ntuj gypsum pob zeb . Nws yog cov khoom siv yam tsis muaj ntxhiab tsw, nws tsis deform thaum raug kub.
Ib qho ntawm nws qhov txiaj ntsig tseem ceeb yog hypoallergenicity thiab kev nyab xeeb ib puag ncig.
Kev nthuav dav ntawm daim ntawv thov gypsum yog ntau yam, nws siv rau:
-
kev tsim khoom ntawm gypsum plasterboards;
- hniav nto tiav;
- kho nyob rau hauv cov ceg ntoo ntawm cov tshuaj xws li traumatology thiab kho hniav;
- ua qauv ntawm cov duab puab thiab tsim cov ntsiab lus ntawm lub tsev facades.
Alabaster tseem yog lub tsev tsim khoom qhuav raws li cov nplua-graps gypsum . Hauv cov txheej txheem ntawm nws cov khoom, kub tau siv heev, vim tias cov yam ntxwv ntawm cov khoom sib txawv los ntawm cov gypsum.
Alabaster tuaj yeem tiv taus raug rau qhov kub thiab txias heev, nyob hauv chav. Hais txog cov khoom siv ib puag ncig zoo thiab nyab xeeb.
Lub sij hawm qhuav yog ib qho ntawm cov yam ntxwv tseem ceeb ntawm cov khoom siv. Nws yog qhov ntsuas no uas cov neeg siv khoom siv tau saib xyuas.
Khov tshwm sim:
- gypsum ua - tom qab 30 feeb tom qab thov rau saum npoo av, tau kawg, yog tias thev naus laus zis rau kev npaj cov tshuaj thiab cov xwm txheej raug tswj hwm;
- alabaster - tom qab 5-10 feeb, uas yog, nrawm dua, vim thev naus laus zis ntawm kev foob pob zeb.
Rau cov laj thawj saum toj no, alabaster tau xaiv los ntawm cov kws tsim kev paub uas paub yuav ua haujlwm nrog cov khoom li cas thiab ua raws nws. Hauv kev ua haujlwm, nws nyuaj heev. Txhawm rau kom lub sijhawm nws qhuav, nws yuav tsum tau siv cov tshuaj tshwj xeeb thiab cov tshuaj ntxiv thaum npaj cov tshuaj. Cov tshuaj no tuaj yeem ua kom qeeb cov tshuaj lom hauv cov khoom sib xyaw, thiab vim qhov no, cov khoom siv tawv tom qab 20-30 feeb.
Dab tsi yog qhov muaj zog?
Lub zog yog lwm qhov tseem ceeb tseem ceeb ntawm cov khoom siv. Qhov muaj zog nws yog, ntseeg tau ntau dua thiab ruaj khov cov khoom tsim los ntawm nws.
Coj mus rau hauv tus account qhov kev paub dhau los thiab ntau qhov kev sim ntsuas tau ua tiav, nws tuaj yeem hais nrog qhov tseeb uas alabaster yog ntau ruaj dua.
Tsis zoo li alabaster, gypsum tsis ua kom tawv. Raws li Mohs nplai, qhov sib npaug ntawm lub zog thiab tawv ntawm cov khoom tau txais 2 cov ntsiab lus - qhov no txhais tau tias cov khoom lag luam ua los ntawm plaster tuaj yeem ua puas txawm siv rau tes. Cov av noo siab hauv chav tuaj yeem ua rau nws tawg.
Tab sis alabaster tau txais 3 cov ntsiab lus, uas yog, nws muaj zog dua, muaj qhov tshwj xeeb los ntawm qib siab ntawm cov nplaum thiab sab hauv, uas ua rau muaj kev sib txuas zoo ntawm cov khoom siv rau saum npoo.
Lawv sib txawv li cas?
Alabaster thiab gypsum raws li cov tsev sib xyaw qhuav muaj qee yam ntawm lub cev thiab cov yam ntxwv zoo. Muaj qhov sib txawv me me ntawm lawv, tab sis tseem muaj qhov sib txawv. Ntxiv rau qhov ntsuas saum toj no (lub zog thiab lub sijhawm qhuav), muaj lwm qhov sib txawv.
Ib puag ncig phooj ywg
Ob qho tib si thiab lwm yam hais txog cov khoom siv ntuj uas tau muab rho tawm los ntawm cov khoom siv raw. Tab sis ua ntej nkag mus rau hauv kev tsim kho kev lag luam, lawv mus dhau tus lej ntawm kev kho mob thev naus laus zis, vim qhov uas lawv muaj pes tsawg leeg thiab cov khoom hloov pauv.
Gypsum yog tus yam ntxwv zoo ib puag ncig thiab kev nyab xeeb , yog li nws tau siv ob qho tib si hauv tshuaj thiab hauv kev tsim kho. Alabaster tsis muaj kev nyab xeeb.
Elasticity
Gypsum yog cov khoom siv mos, nws yooj yim los ua haujlwm nrog nws, tab sis nws nyuaj rau hu nws ua ywj. Heev feem ntau, tshwj xeeb tshaj yog nyob rau hauv tes tsis muaj peev xwm thiab tsis muaj kev paub, cov khoom tawg.
Alabaster, ntawm qhov tod tes, nyuab dua thiab muaj zog dua, tab sis qhuav sai dua. Koj tuaj yeem txua ib yam dab tsi los ntawm nws, tab sis koj yuav tsum tau ua haujlwm nrawm kom nws tsis muaj sijhawm nyuaj.
Qhuav
Qhov sib txawv tseem ceeb ntawm cov khoom siv yog kev siv tshuab. Txhua tus ntawm lawv yuav tsum tau kho cua sov, tsuas yog qis qis ua rau ntawm gypsum, thiab kub siab ntawm alabaster. Raws li qhov tshwm sim, cov dej noo ntau nyob hauv thawj, thiab yav tom ntej, pwm thiab lwm yam kab mob tuaj yeem tsim rau nws. Alabaster, ntawm qhov tod tes, yuav luag tag nrho lub cev qhuav dej tom qab ua tiav, uas yog vim li cas pwm thiab kab mob tsis tshwm ntawm nws.
Ntxiv rau qhov sib txawv saum toj no, muaj ob peb ntxiv
- Alabaster cov ntsiab lus thiab cov txheej txheem yog tawg-resistant . Ntawm gypsum, cov kab tawg ib txwm tshwm sim, uas ua rau muaj kev puas tsuaj sai.
- Soundproofing … Alabaster yog tus yam ntxwv los ntawm lub suab rwb thaiv tsev zoo dua.
- Alabaster, ua tsaug rau nws kom qhuav sai, feem ntau siv raws li kev ntxiv rau lwm cov kev daws teeb meem , kom ceev lub sij hawm kom qhuav.
- Sib tov cov tshuaj rau siv ntxiv . Kev sib xyaw cov tshuaj khib nyiab yog yooj yim dua. Qhov no yog vim qhov tseeb tias nws tsis nkag siab ntev.
Raws li koj tuaj yeem pom, cov ntaub ntawv no muaj ntau qhov sib txawv. Hais txog qhov zoo sib xws, peb tuaj yeem pom qhov dav thiab qhov tsis sib xws ntawm txhua yam ntawm cov khoom siv.
Qhov kev xaiv zoo tshaj yog dab tsi?
Nws nyuaj hais cov tshuaj twg zoo dua thiab qhov twg yog qhov tsim nyog siv. Txhua yam nws nyob ntawm lub hom phiaj twg koj xav siv cov khoom siv rau.
Nws tsis muaj qhov zais cia tias gypsum tau siv ntau dua li alabaster. Qhov no yog vim qhov tseeb tias cov khoom siv tau yooj yim dua los ua haujlwm nrog. Muaj ntau hom gypsum.
Tsev … Nws yog siv nyob rau hauv tus txheej txheem ntawm kev ua haujlwm plastering. Txiv qaub tau ntxiv rau hauv kev daws teeb meem txhawm rau txhawm rau ua kom muaj kev ywj pheej. Nws yog qhov zoo tagnrho rau sab hauv tiav hauv chav qhuav. Plaster ntawm Paris tuaj yeem siv tsis tau plaster.
Siab zog … Kev faib hluav taws, cov av thiab cov plooj (porcelain) cov khoom siv huv huv tau tsim los ntawm nws hnub no. Thiab tseem cov khoom tau pom daim ntawv thov tshuaj.
Polymeric … Hom gypsum no feem ntau siv hauv kev puas siab puas ntsws.
Duab puab … Qhov tsis tseem ceeb rau kev tsim ntau yam khoom siv tes ua - duab puab, khoom plig. Hauv kev lag luam aviation thiab tsheb, nws yog siv rau kev tsim khoom ntawm cov khoom thiab cov txheej txheem.
Acrylic … Nws tau siv dav hauv txheej txheem kho kom zoo nkauj sab hauv. Nws yog siv rau kev tsim khoom ntawm stucco, pob zeb zoo nkauj.
Alabaster tuaj yeem siv tshwj xeeb hauv kev tsim kho kev lag luam. Qhov no yog cov khoom siv tiv thaiv hluav taws, yog li nws tsim nyog rau kev ua tiav thaj chaw nrog qib siab ntawm kev nyab xeeb hluav taws xav tau. Cov khoom sib xyaw tuaj yeem siv rau hauv cov txheej txheem ntawm kev ua haujlwm hluav taws xob, piv txwv li, rau kev teeb tsa lub thawv ntsaws.
Dhau li ntawm qhov kev thov, thaum xaiv, koj yuav tsum coj mus rau hauv tus account koj tus kheej kev paub hauv kev ua haujlwm nrog cov tsev sib xyaw no.
