Alabaster Yog lub tsev qhuav sib xyaw, uas yog tau los ntawm kev hlawv cov nyom gypsum. Cov khoom siv feem ntau siv hauv kev tsim kho thiab kho rau kev tsim cov phiaj hlau, vaj huam sib luag, txhaws qhov tawg lossis nqaws, thiab kho kom zoo nkauj. Nws, zoo ib yam li lwm lub tsev thiab cov khoom siv tiav, muaj qee lub cev thiab cov txuj ci tsis zoo thiab cov yam ntxwv.

Ib qho ntawm cov khoom tseem ceeb ntawm alabaster uas tau them nyiaj mloog yog lub sijhawm qhuav. Cov khoom siv yog cov khoom siv kom qhuav kom qhuav, yog li qee qhov txuj ci xav tau los ua haujlwm zoo nrog nws.

Qhuav cov kauj ruam raws li qhov xwm txheej ib txwm muaj

Kev tsim kho qhuav sib xyaw alabaster muaj gypsum, cov tshuaj polymer thiab cov khoom siv ib puag ncig zoo. Nws yoog raws, tsis kub hnyiab thiab tuaj yeem tiv taus qhov kub siab heev.

Feem ntau, cov khoom siv hauv cov txheej txheem:

• kho qhov tsis xws luag ntawm phab ntsa;
• kev npaj saum npoo av ua ntej thov kev ua tiav;
• hluav taws xob ua haujlwm;
• kho kom zoo nkauj sab hauv.

Txhawm rau kom txoj haujlwm ua haujlwm tau zoo thiab ua haujlwm tau zoo, koj yuav tsum paub lub sijhawm kom qhuav ntawm alabaster ntawm phab ntsa tom qab thov, hauv daim ntawv tom qab kneading, hauv qhov hluav taws xob.

Nyob ntawm lub sijhawm kom qhuav, alabaster tau muab cais ua 3 pawg

• Qhuav qhuav … Tom qab ob peb feeb, cov khoom siv tam sim pib teeb tsa nrog cov nplaim, thiab tom qab 20 feeb, kev ua tiav tiav tiav tshwm sim.
• Nruab nrab (ib txwm) kom qhuav nrawm … Qhov no teev nyob rau hauv 6 feeb, thiab tawv tom qab 30 feeb.
• Qhuav kom qeeb . Tsuas yog 25 feeb tom qab thov daim ntawv cov ntaub ntawv pib teeb rau saum npoo.

Txhua hom saum toj no ntawm alabaster yog tus yam ntxwv ntawm qee lub sijhawm ntawm lub sijhawm uas lub alabaster mus dhau txhua theem ntawm ziab.

Lub sijhawm ua kom qhuav ntawm alabaster raws li qhov xwm txheej ib txwm muab faib ua theem:

• tsis pub dhau 5-8 feeb tom qab thov rau saum npoo, nws pib teeb tsa;

• tom qab 25-40 feeb, nws yuav tsum ua kom tiav ntawm qhov chaw;
• tom qab 2-3 teev, theem pib ntawm lub zog tau mus txog, uas tuaj yeem tiv taus lub nra hnyav txog 6 MPa;
• tsuas yog tom qab 24-48 teev tom qab thov, cov khoom qhuav tag.

Tau kawg, cov sijhawm no tuaj yeem hloov pauv. Cov ncauj lus kom ntxaws ntxiv txog ntev npaum li cas cov sib tov twb tau thov rau saum npoo yuav qhuav tuaj yeem pom los ntawm kev saib ntawm lub thawv ntim khoom lag luam.

Cov chaw tsim khoom yuav tsum qhia qhov ntsuas no.

Yam dab tsi cuam tshuam txog kev ua kom tiav?

Tau kawg, koj yuav tsum coj mus rau hauv tus account cov ntaub ntawv muab los ntawm cov khw. Tab sis, ntxiv rau qhov no, nws yog qhov yuav tsum tau coj mus rau hauv tus account lwm yam uas cuam tshuam rau lub sijhawm ua kom qhuav ntawm alabaster.

Lub sij hawm ziab ntawm cov khoom nyob ntawm ntau yam nuances

• Txheej tuab. Yog tias nws tuab, cov khoom siv sijhawm ntev kom qhuav. Cov khoom siv pib nkag mus rau saum npoo tom qab 5-6 feeb, tab sis theem pib ntawm kev teeb tsa thiab ua kom qhuav tas ntev dua.
• Cua av coefficient. Yog tias nws nyob sab hauv tsev lossis sab nraum zoov, cov txheej txheem ua qeeb.
• Cua kub. Qhov kub ntawm huab cua ntau dua, cov ntaub ntawv yuav qhuav sai dua.
• Qhov sib xws ntawm kev npaj sib xyaw. Lub xov tooj txawb (kua) ua kom qhuav ntev dua li tuab.
• Hom thiab muaj pes tsawg leeg. Txhua yam tshuaj uas ua rau alabaster cuam tshuam rau lub sijhawm teeb tsa ntawm kev sib xyaw.

Los ntawm qhov tau hais ua ntej, peb tuaj yeem xaus tias nws yog qhov xav tau los ua haujlwm nrog alabaster raws li qhov xwm txheej ib txwm muaj - nrog cov av noo ib txwm muaj, huab cua sov . Yog tias txoj haujlwm yuav tsum tau ua tam sim ntawd, thiab cov xwm txheej sab hauv tsev lossis sab nraum zoov tsis tau raws li qhov yuav tsum tau ua, nco ntsoov tias cov theem kev ua kom qhuav tas yuav siv sijhawm ntev dua.

Dab tsi ntxiv kom khov qeeb dua?

Feem ntau muaj cov xwm txheej thaum nws yog qhov tsim nyog kom qeeb lub sijhawm ua kom qhuav ntawm cov khoom. Dab tsi tuaj yeem ua tiav kom tsis txhob ua kom nrawm dua ntawm kev ua kom ruaj khov, tab sis, ntawm qhov tsis sib xws, kom qeeb cov txheej txheem no?

Muaj ntau txoj hauv kev sim sijhawm uas koj tuaj yeem siv tau . Txhawm rau kom qeeb cov txheej txheem kom qhuav ntawm qhov sib tov, thaum npaj cov tshuaj, qee yam tshuaj yuav tsum tau ntxiv rau nws.

• Pob txha kua nplaum … Nws kuj tseem tuaj yeem pleev xim lossis kua nplaum ntoo. Qhov tseem ceeb yog tsis txhob ua dhau nws. Nws cov nyiaj yuav tsum tsis pub tshaj 2% ntawm tag nrho qhov hnyav ntawm cov khoom sib xyaw npaj.
• Txiv qaub kua txiv … Txoj kev no tsis tshua siv vim nws tuaj yeem muab cov txiaj ntsig sib txawv txhua lub sijhawm. Qhov tshaj plaws yog tias tus nqi ntawm citric acid tuaj yeem sib txawv nyob ntawm seb hom alabaster. Nws yuav siv ntau qhov kev sim ua kom raug kwv yees qhov feem. Qhov nruab nrab, rau 100 grams ntawm alabaster, koj yuav tsum noj li 5-6 cov kua qaub.
• PVA kua nplaum . Cov kws tshaj lij hais tias 3% kua nplaum ntxiv rau cov tshuaj alabaster ua rau lub sijhawm tawv tawv. Tab sis thaum ntxiv PVA rau qhov sib xyaw, koj yuav tsum tau ua haujlwm sai, txij li zaj duab xis yuav pib tsim rau ntawm qhov chaw ntawm cov tshuaj, uas yuav thaiv qhov ua kom cov kua ua kua, yog li ua rau txo qis hauv lub zog yam ntxwv ntawm alabaster.

Feem ntau, cov pib tsim khoom lossis yooj yim tsis muaj txuj ci amateurs uas tsis paub yuav ua haujlwm nrog alabaster thiab txhawj xeeb tias lawv yuav tsis ua raws cov khoom siv mus rau cov txheej txheem ntawd.

Tab sis cov kws tshaj lij tseem pom zoo kom tsis txhob dilute cov khoom, yog li tsis txo nws cov khoom muaj txiaj ntsig thiab yam ntxwv.
