Compound qhuav mix additives
Compound qhuav mix additives yog cov khoom xyaw uas ntxiv rau qhuav mix formulations, xws li pob zeb los yog mortar, los txhim kho lawv cov kev ua tau zoo thiab cov khoom.Cov additives no tuaj yeem suav nrog ntau yam khoom siv xws li polymers, accelerators, retarders, air entraining agents, thiab water reducers.
Polymers feem ntau tau ntxiv los txhim kho qhov adhesion, durability, thiab saj zawg zog ntawm kev sib tov.Accelerators yog siv los ua kom lub teeb thiab hardening ntawm qhov sib tov, thaum cov retarders qeeb cov txheej txheem teeb tsa.Cov cua entraining cov neeg ua hauj lwm tau ntxiv los tsim cov pa microscopic hauv cov khoom sib xyaw, uas txhim kho nws txoj haujlwm, khov-thaw tsis kam, thiab kav ntev.Cov dej reducers yog siv los txo cov dej uas xav tau hauv kev sib tov, uas tuaj yeem txhim kho nws lub zog thiab kav ntev.
Cov hom tshwj xeeb thiab tus nqi ntawm cov khoom siv ntxiv yuav nyob ntawm qhov xav tau ntawm cov khoom kawg, nrog rau cov khoom siv hauv kev sib xyaw.Ua tib zoo xaiv thiab siv cov khoom siv no kom zoo tuaj yeem pab txhim kho kev ua haujlwm thiab kev ua haujlwm ntev ntawm cov khoom sib tov qhuav.
Ntxiv rau cov additives uas tau hais los saum toj no, kuj tseem muaj lwm hom kev sib xyaw qhuav mix additives uas tuaj yeem siv tau.Piv txwv li, silica fume yog cov khoom siv zoo uas tuaj yeem muab ntxiv rau cov pob zeb sib xyaw kom txhim kho nws lub zog, ua haujlwm ntev, thiab tiv thaiv tshuaj tua kab mob.Fly tshauv, ib qho khoom siv los ntawm cov chaw tsim hluav taws xob hluav taws xob hluav taws xob, kuj tuaj yeem siv los hloov qee cov cement hauv cov pob zeb sib xyaw, uas tuaj yeem txo qhov kev cuam tshuam ib puag ncig ntawm kev sib xyaw thaum txhim kho nws lub zog thiab kav ntev.
Lwm yam additives yog plasticizers, uas yog siv los txhim kho kev ua hauj lwm thiab khiav ntawm cov pob zeb sib tov, ua rau lawv yooj yim los tuav thiab qhov chaw.Cov no tuaj yeem yog cov dej txo qis lossis tsis muaj dej-txo cov yas yas, nyob ntawm seb lawv kuj txo cov dej uas xav tau hauv kev sib tov.
Nyob rau hauv cov ntsiab lus, compound qhuav mix additives yuav zoo heev txhim khu lub zog ntawm qhuav mix formulations xws li pob zeb thiab mortar.Los ntawm kev ua tib zoo xaiv thiab siv cov additives uas tsim nyog, kev ua tau zoo, kev ua haujlwm ntev, thiab kev ua haujlwm ntawm cov ntaub ntawv no tuaj yeem txhim kho tau zoo, ua rau cov khoom zoo dua qub.
