1. Sib tov
Ua ntej ntxiv lub hnab loj ntawm cov ntaub ntawv mus rau lub tov khoom, ces ntxiv lub hnab me me ntawm cov ntaub ntawv, qhuav rau 1-2 feeb, ces ntxiv txog 90% ntawm cov dej thiab sib tov rau 2-3 feeb. Thaum ntxiv dej thiab nplawm, lub sijhawm sib xyaw ntub dej yuav tsum tsis pub tsawg tshaj 5 feeb. Cov dej ntim ntxiv yog kho raws li qhov xwm txheej. Thaum koj xav tau ntxiv dej ntxiv, txuas ntxiv stirring rau 1-2 feeb tom qab ntxiv dej. Siv lub ntsuas ntsuas thaum ntxiv dej los xyuas kom meej lub zog ntawm cov khoom.
2. Pouring kev tsim kho
Cov castable sib xyaw yuav tsum tau nchuav sai sai, thiab cov khoom sib xyaw castable yuav tsum tau nchuav rau hauv pwm, feem ntau hauv 20 feeb. Thaum lub castable nto yog dej nyab thiab ntws, txav lub vibrating pas nrig. Lub vibration yuav tsum tau nqa tawm mechanically nrog ib tug portable vibrator thiab ua ke nrog phau ntawv mashing. Qhov txav ceev yog 1-2 meters / feeb. Lub sij hawm vibration yuav tsum tsis txhob ntev dhau, thiab yuav tsum tsis txhob muaj qhov to lossis kev co ntau dhau. Tom qab kev vibration tiav, thaum rub tawm lub vibrator, qhov ceev yuav tsum qeeb, txwv tsis pub nws yuav deflect, cuam tshuam rau cov khoom, lub zog thiab kev ua haujlwm. Ua ntej qhov kawg ntawm pouring, qhov kub ntawm qhov chaw yuav tsum tau khaws cia siab tshaj 5 degree. Yog tias qhov kub ntawm qhov chaw qis qis, kev tiv thaiv cua sov tuaj yeem ua tau, txwv tsis pub nws yuav ua rau muaj kev cuam tshuam thiab txo cov khoom lag luam.
3. Kev tu
Tom qab cov khoom siv pouring hardens, qhov saum npoo ntawm lub cev yuav tsum tau them nrog polyethylene yas zaj duab xis tam sim ntawd, thiab lub sij hawm demoulding yuav tsum tsis pub tsawg tshaj 96 teev tom qab pouring ntawm 20 degree rau 48 teev. Qhov kub yuav tsum qis dua 20 degree. Thaum lub sij hawm tu txheej txheem, txuas ntxiv npog nrog polyethylene yas zaj duab xis thiab ntub straw hnab castables. Tom qab ntub dej, kev kho cua sov nruj yuav tsum tau nqa tawm, thiab nws tuaj yeem siv tau tsuas yog tom qab dhau qhov txheej txheem ci.
