1. Pub qib calcium formate: 1. Raws li hom tshiab pub additive.Pub calcium formate kom nce qhov hnyav thiab siv calcium formate ua cov khoom noj ntxiv rau piglets tuaj yeem txhawb kev qab los noj mov ntawm piglets thiab txo tus nqi raws plab.Ntxiv 1% mus rau 1.5% calcium formate rau piglet noj tuaj yeem txhim kho kev ua tau zoo ntawm cov piglets weaned.Ib txoj kev tshawb fawb German pom tau hais tias ntxiv 1.3% calcium formate rau kev noj zaub mov ntawm cov piglets weaned tuaj yeem txhim kho qhov hloov pauv hloov pauv ntawm 7% mus rau 8%, thiab ntxiv 0.9% tuaj yeem txo qhov tshwm sim ntawm piglet raws plab.Zheng Jianhua (1994) ntxiv 1.5% calcium formate rau kev noj zaub mov ntawm 28-hnub-hnub weaned piglets rau 25 hnub, qhov nce txhua hnub ntawm piglets nce 7.3%, pub hloov pauv tus nqi nce 2.53%, thiab kev siv cov protein thiab lub zog siv. tus nqi nce los ntawm 10.3% feem.thiab 9.8%, piglet raws plab tau txo qis.Wu Tianxing (2002) ntxiv 1% calcium formate rau kev noj zaub mov ntawm ternary hybrid weaned piglets, qhov nce txhua hnub tau nce los ntawm 3%, kev hloov pauv hloov pauv tau nce los ntawm 9%, thiab piglet raws plab tau txo los ntawm 45.7%.Lwm yam uas yuav tsum tau nco ntsoov yog: kev siv cov calcium formate zoo ua ntej thiab tom qab yuag, vim tias hydrochloric acid secreted los ntawm piglets nce nrog hnub nyoog;calcium formate muaj 30% yooj yim nqus calcium, yog li ua tib zoo saib xyuas cov calcium thiab phosphorus thaum tsim cov khoom noj.kev faib ua feem.
2. Muaj qib calcium formate:
(1) Kev tsim kho kev lag luam: raws li tus neeg sawv cev ceev ceev, roj nplua nyeem thiab cov neeg ua kom qhuav rau cov cement.Nws yog siv nyob rau hauv kev tsim kho mortar thiab ntau yam concretes kom ceev lub hardening ceev ntawm xis mas thiab txo lub sij hawm teem, tshwj xeeb tshaj yog nyob rau hauv lub caij ntuj no kev tsim kho, kom tsis txhob qeeb heev ceev ntawm qhov kub thiab txias.Lub demoulding yog ceev, kom cov cement tuaj yeem siv sai li sai tau.
(2) Lwm yam kev lag luam: tanning, hnav-resistant cov ntaub ntawv, thiab lwm yam.
Daim ntawv thov
1.Pub Qib Calcium Formate: Pub Additives
2. Qib Kev Lag LuamCalcium Formate:
(1) Kev Tsim Kho Siv: Rau cov cement, ua coagulant, lubricant; Forbuilding mortar, rau acceleration cement lub hardening.
(2) Lwm yam Kev Siv: Rau tawv, cov ntaub ntawv tiv thaiv hnav, thiab lwm yam
Calcium formate yog cov khoom siv ntau heev hauv cov txheej txheem kho kom zoo nkauj.Nws qhov sib ntxiv tuaj yeem txhim kho kev ua haujlwm thiab kev ruaj ntseg ntawm gypsum mortar.Yog li dab tsi yog qhov zoo ntawm calcium formate hauv gypsum mortar?
Ua ntej, calcium formate tuaj yeem ceev tus nqi ntawm gypsum condensation.Gypsum mortar yuav tsum muaj lub sijhawm teem sijhawm thaum lub sijhawm tsim kho kom ntseeg tau tias cov mortar tuaj yeem kho tau thiab tawv.Ntxiv cov calcium formate kom tsim nyog tuaj yeem ncua qhov kev teeb tsa ntawm gypsum mortar, kom cov neeg ua haujlwm tsim kho muaj sijhawm txaus los ua haujlwm thiab kho, txhawm rau txhim kho kev tsim kho.
Thib ob, calcium formate muaj qhov cuam tshuam loj rau lub zog thiab hardness ntawm gypsum mortar.Calcium formate nyob rau hauv gypsum mortar tuaj yeem hnov mob nrog hydration hardening khoom hauv gypsum los tsim cov qauv siv lead ua ruaj khov.Cov tshuaj tiv thaiv no tuaj yeem txhim kho lub zog thiab hardness ntawm gypsum mortar, ua rau nws ruaj khov thiab ruaj khov.Nyob rau tib lub sijhawm, calcium formate kuj tuaj yeem txhim kho qhov kev sib tsoo ntawm gypsum mortar thiab txo qhov teeb meem tawg los ntawm qhov qhuav qhuav.
Tsis tas li ntawd, calcium formate tuaj yeem txhim kho cov dej tsis kam thiab ua haujlwm ntev ntawm gypsum mortar.Thaum gypsum mortar ntsib cov dej los yog cov av noo, nws yog ib qho yooj yim rau soften thiab yaj.Los ntawm kev ntxiv cov calcium uas tsim nyog, nws tuaj yeem hnov mob nrog dej los tsim cov khoom ruaj khov, yog li lub peev xwm ntawm gypsum los tiv thaiv dej yaig kuj tau txhim kho zoo heev.Nyob rau hauv txoj kev no, txawm hais tias nws yog nyob rau hauv lub plum nag los yog lwm yam huab cua ntub heev rau lub sij hawm ntev, nws tsis yooj yim cuam tshuam los ntawm cov av noo hloov.
Tsis tas li ntawd, calcium formate tuaj yeem txhim kho kev ua haujlwm thiab kev tsim kho ntawm gypsum mortar.Tom qab ntxiv calcium formate, fluidity thiab viscosity ntawm gypsum mortar yog txhim kho, uas ua rau kev tsim kho yooj yim dua.Cov neeg ua haujlwm tsim kho tuaj yeem tswj tau qhov fluidity thiab cohesiveness ntawm mortar, thiaj li kom tau txais cov txiaj ntsig zoo dua qub thiab du.
Yog li ntawd, lub luag hauj lwm ntawm calcium formate nyob rau hauv industrial engineering ua tsis yog yuav tsum tau underestimated.Nws tuaj yeem txo lub sijhawm teeb tsa ntawm gypsum mortar kom ntau li ntau tau, nce lub zog thiab hardness ntawm mortar, txhim kho dej tsis kam thiab kav ntev, thiab tseem txhim kho kev ua haujlwm thiab kev tsim kho.Yog li ntawd, thaum siv gypsum mortar, ntxiv calcium formate yog ib qho kev txhim kho zoo, uas tuaj yeem txhim kho qhov zoo thiab kev ua haujlwm ntawm mortar thiab ua tau raws li qhov xav tau ntawm kev kho kom zoo nkauj hauv tsev sib txawv.
