Dab tsi yog gypsum retarder?

gypsum retarderyog ib qho tshuaj ntxiv uas siv los tsim cov khoom siv gypsum, xws li plaster, wallboard (drywall), thiab gypsum-raws li mortars. Nws lub luag haujlwm tseem ceeb yog kom txo qis lub sijhawm teeb tsa ntawm gypsum, tso cai rau kev ua haujlwm ntev thiab kev tswj xyuas ntau dua. Ntawm no yog cov ntsiab lus ntawm gypsum retarders:

Muaj nuj nqi:

• Kev ncua sij hawm ncua sij hawm: Lub luag haujlwm tseem ceeb ntawm gypsum retarder yog ncua sijhawm teem sijhawm ntawm cov khoom siv gypsum. Qhov no prolongs lub workability ntawm cov khoom, tso cai rau kom yooj yim tuav, daim ntawv thov, thiab tiav.

Kev sib xyaw:

• Chemical Agents: Gypsum retarders feem ntau muaj cov tshuaj sib txuas uas cuam tshuam nrog cov txheej txheem dej ntawm gypsum. Cov tshuaj tiv thaiv kab mob muaj xws li cov organic acids, phosphates, lignosulfonates, gluconates, thiab lwm yam kev tsim tawm.
• Admixtures: Gypsum retarders yuav muab tau ua kua los yog hmoov admixtures uas tau ntxiv rau cov khoom siv gypsum thaum sib tov lossis tsim khoom.

Properties thiab yam ntxwv:

• Kev Ua Haujlwm Txuas Ntxiv: Cov gypsum retarders tso cai rau kev ua haujlwm ntev ntawm cov ntaub ntawv gypsum, muab sijhawm rau cov neeg siv sijhawm ntxiv thiab tswj cov khoom ua ntej nws teeb tsa.
• Txhim kho kev ua tiav: Los ntawm kev ua kom lub sij hawm qeeb, gypsum retarders tuaj yeem pab ua kom tiav ib qho smoother thiab zoo ib yam, txo qhov kev pheej hmoo ntawm qhov tsis xws luag xws li tawg lossis tsis sib xws.
• Tswj Chaw: Retarders muab kev tswj kom zoo dua ntawm cov txheej txheem teeb tsa, tso cai rau kev hloov kho kom haum rau cov khoom sib xws thiab cov txheej txheem siv raws li xav tau.

Daim ntawv thov:

• Kev tsim kho: Gypsum retarders feem ntau siv hauv kev tsim kho kev lag luam rau kev tsim cov khoom siv gypsum xws li plaster, wallboard, sib koom ua ke, thiab gypsum-based mortars.
• Kev kos duab thiab duab puab: Hauv kev kos duab thiab duab puab, gypsum retarders tuaj yeem siv los txuas ntxiv lub sijhawm ua haujlwm ntawm gypsum plaster lossis cov ntaub ntawv casting, tso cai rau cov neeg ua yeeb yam los tsim cov qauv tsim thiab cov ntsiab lus.

Kev nyab xeeb thiab tuav:

• Gypsum retarders yuav tsum tau saib xyuas thiab siv raws li cov chaw tsim khoom cov lus qhia thiab cov lus qhia kev nyab xeeb.
• Cov khoom siv tiv thaiv xws li hnab looj tes, tsom iav, thiab lub qhov ncauj qhov ntswg yuav tsum tau hnav thaum tuav cov gypsum retarders kom tsis txhob sib cuag ntawm daim tawv nqaij, nqus pa, lossis nqus tau.
• Kev khaws cia kom zoo yuav tsum tau tswj xyuas kom tsis txhob muaj kab mob los yog degradation ntawm cov khoom retarder.

Compatibility:

• Nws yog ib qho tseem ceeb los xyuas kom meej tias gypsum retarder xaiv tau sib xws nrog cov khoom siv tshwj xeeb gypsum. Kev ntsuam xyuas kev sib raug zoo yuav tsim nyog thaum siv cov retarders nrog txawv gypsum formulations los yog additives.

Gypsum retarders ua lub luag haujlwm tseem ceeb hauv kev tswj lub sijhawm teem sijhawm thiab kev ua haujlwm ntawm cov ntaub ntawv gypsum, muab cov txiaj ntsig xws li ncua sijhawm ua haujlwm, txhim kho tiav, thiab tswj cov txheej txheem zoo dua. Los ntawm kev xaiv qhov tsim nyog retarder thiab siv nws kom raug, cov tuam ntxhab thiab cov neeg siv cov khoom siv gypsum tuaj yeem ua tiav qhov kev ua tau zoo thiab zoo hauv lawv daim ntawv thov.
