Tau ntev lawm, cov ntaub ntawv siv rau phab ntsa hauv kev tsim kho tseem yog cov txiv qaub ntsuab ib txwm muaj. Cov kua qaub ntsuab kub hnyiab yuav tsum tau dhau los ntawm cov txheej txheem ntawm kev tua dej, txau, thiab laus, thiab tom qab ntawd ntxiv cov ntaub ntawv fiber xws li riam hemp kom sib xyaw ua ke ua ntej kev tsim kho. Nws cov txheej txheem yog ntau yam, tus nqi siab, lub zog qis, shrinkage loj, ntshai dej, thiab phab ntsa yooj yim tawg, vau, npuas, poob thiab lwm yam tsis zoo. HCMilling (Guilin Hongcheng), ua tus tsim khoom ntawmcov khoom siv tsim cov hmoov sib xyaw rau cov ntaub ntawv siv hauv tsev, yuav qhia txog txoj kev tsim cov hmoov dawb sib xyaw rau cov ntaub ntawv siv hauv tsev nrog limestone ua cov khoom siv tseem ceeb, tus nqi qis, lub zog siab thiab kev nqus dej zoo.

Cov kua qaub ntsuab thiab gypsum putty tsim nyob rau xyoo tas los no siv tau yam tsis ntxiv cov ntaub ntawv fiber, tab sis tus qub yog ua los ntawm kev ntxiv gypsum ntawm qhov sib npaug, nrog tus nqi siab dua li cov txiv qaub ntsuab ib txwm muaj, thiab phab ntsa tseem tawg. Tus tom kawg yog ua los ntawm kev ntxiv ntau yam khoom ntxiv rau hauv hmoov gypsum, nrog tus nqi siab, thiab tuaj yeem siv rau hauv cov tsev siab dua, uas tsis haum rau cov tsev ib txwm muaj thiab cov tsev nyob hauv zej zog. Yuav ua li cas tsim cov hmoov sib xyaw ua ke? Li Yinghai thiab Li Jing tau tshaj tawm txoj kev tsim cov hmoov dawb sib xyaw rau kev tsim kho, uas siv limestone ua cov khoom siv raw tseem ceeb, ntxiv qee qhov ntawm cov thee gangue, lossis sib xyaw ntawm silica, txhuas trioxide thiab thee, thiab xa nws mus rau hauv lub qhov cub kom raug calcined rau 72-120 teev ntawm qhov kub ntawm 1100-1200 ℃, uas yog cov khoom siv laus, thiab tom qab ntawd ntxiv cov hmoov gypsum tsim nyog rau clinker, uas yog cov khoom tiav tom qab sib tsoo. Nws cov khoom siv raw los ntawm ntau qhov chaw. Thee gangue tuaj yeem siv los hloov cov khib nyiab mus rau hauv cov khoom muaj nqis, thiab nws cov mis yog qhov tshwj xeeb. Cov khoom muaj ob qho kev ua tau zoo ntawm cov txiv qaub ntsuab ib txwm muaj thiab cement. Nws muaj lub zog siab, kev nqus dej zoo thiab tus nqi qis. Nws tsis tas yuav sib xyaw nrog cov khoom siv fiber xws li riam hemp. Nws tuaj yeem plastered los ntawm kev sib xyaw nrog dej ncaj qha. Nws muaj kev nplaum zoo, tsis muaj npuas lossis tawg ntawm phab ntsa, thiab nws kuj tuaj yeem siv los ntawm kev ntxiv cov xim rau xim. Nws yog cov khoom siv hauv tsev tshiab uas hloov cov txiv qaub ntsuab ib txwm muaj.

Cov txheej txheem saum toj no yog calcined hauv lub cub tawg ntsug, thiab cov khoom tiav tuaj yeem ua los ntawm kev sib tsoo cov limestone mus rau 170-180 meshes nrog antsuglub menyuamlub zebCov txheej txheem yooj yim, uas yog qhov zoo rau kev tsim khoom siv tshuab loj. HCMilling (Guilin Hongcheng), ua tus tsim cov khoom siv tsim khoom siv hmoov, tau siv dav Raymond zeb limestone, pob zeb av nplaumntsug roller zebthiab lwm yam khoom siv tsim hmoov hauv kev tsim cov haujlwm tsim hmoov. Qhov ua tiav ntawm cov txheej txheem yog kho tau ntawm 80-600 meshes. Rau kev tsim cov hmoov hauv tsev, nws muaj qhov zoo ntawm cov zis loj, kev teeb tsa yooj yim thiab lwm yam. Yog tias koj muaj cov kev xav tau yuav khoom, thov hu rau peb kom paub meej ntxiv txog cov khoom siv thiab muab cov ntaub ntawv hauv qab no rau peb:
