Rau ib ntev lub sij hawm, cov phab ntsa plastering cov ntaub ntawv uas siv nyob rau hauv lub tsev tsim yog tseem yog cov tsoos txiv qaub.Lub burnt quicklime yuav tsum mus los ntawm cov txheej txheem ntawm dej blasting, tshuaj tsuag, thiab kev laus, thiab ces ntxiv fiber ntau ntaub ntawv xws li hemp riam los sib tov tusyees ua ntej kev tsim kho.Nws cov txheej txheem muaj ntau yam, tus nqi siab, tsis tshua muaj zog, shrinkage loj, ntshai dej, thiab cov phab ntsa yog nquag tawg, tawg, npuas, poob thiab lwm yam tsis xws luag.HCMilling (Guilin Hongcheng), ua cov chaw tsim khoom ntawmcompound hmoov ntau lawm khoom rau cov khoom siv hauv tsev, yuav qhia txog kev tsim cov hmoov dawb hmoov rau cov khoom siv hauv tsev nrog limestone ua cov khoom siv tseem ceeb, tus nqi qis, lub zog siab thiab kev nqus dej zoo.

Cov txiv qaub hluavtaws thiab gypsum putty tsim nyob rau hauv xyoo tas los no tuaj yeem siv tsis tau ntxiv cov ntaub ntawv fiber ntau, tab sis yav dhau los yog tsim los ntawm kev ntxiv gypsum ntawm qhov sib npaug, nrog tus nqi siab dua li cov txiv qaub ib txwm, thiab cov phab ntsa tseem tawg.Cov tom kawg yog tsim los ntawm kev ntxiv ob peb additives hauv gypsum hmoov, nrog tus nqi siab, thiab tuaj yeem siv rau hauv cov tsev siab dua, uas tsis haum rau cov vaj tsev zoo tib yam thiab cov vaj tsev nyob.Yuav ua li cas los tsim lub tsev compound hmoov?Li Yinghai thiab Li Jing tau nthuav tawm ib txoj kev tsim cov hmoov dawb sib xyaw rau kev tsim kho, uas siv limestone ua cov khoom siv tseem ceeb, ntxiv qee qhov ntawm cov coal gangue, los yog sib tov ntawm silica, aluminium trioxide thiab thee, thiab xa mus rau hauv cov ncej. kiln yuav tsum tau calcined rau 72-120 teev ntawm qhov kub ntawm 1100-1200 ℃, uas yog cov ntaub ntawv mature, thiab ces ntxiv ib tug tsim nyog tus nqi ntawm gypsum hmoov rau lub clinker, uas yog cov khoom tiav tom qab sib tsoo.Nws cov khoom siv raw yog los ntawm ntau qhov chaw.Coal gangue tuaj yeem siv los hloov cov khoom pov tseg rau hauv cov khoom muaj nqis, thiab nws cov mis yog qhov tshwj xeeb.Cov khoom muaj kev ua tau zoo dual ntawm cov txiv qaub thiab cov cement.Nws muaj lub zog siab, kev nqus dej zoo thiab tus nqi qis.Nws tsis tas yuav tsum tau tov nrog cov ntaub ntawv fiber ntau xws li riam hemp.Nws tuaj yeem plastered los ntawm kev sib xyaw ncaj qha nrog dej.Nws muaj zog adhesion, 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.

Cov txheej txheem saum toj no yog calcined nyob rau hauv ib lub qhov cub ntsug, thiab cov khoom tiav tuaj yeem ua los ntawm kev sib tsoo cov limestone rau 170-180 meshes nrog ib tugntsugcov menyuamzeb.Cov txheej txheem khiav yog yooj yim, uas yog conducive rau loj-scale mechanized ntau lawm.HCMilling (Guilin Hongcheng), raws li cov chaw tsim khoom ntawm cov khoom siv hauv tsev hmoov cov khoom siv, tau siv dav Limestone Raymond zeb, limestonentsug roller millsthiab lwm yam khoom siv hauv tsev hmoov cov khoom siv hauv kev tsim cov hmoov nplej ntau lawm.Qhov kev ua kom zoo yog kho tau ntawm 80-600 meshes.Rau kev tsim cov hmoov hauv tsev, nws muaj qhov zoo ntawm cov khoom siv loj, cov qauv yooj yim thiab lwm yam.Yog tias koj muaj qhov xav tau ntawm kev yuav khoom, thov hu rau peb kom paub meej cov khoom siv thiab muab cov ntaub ntawv ua raws li peb:
