Kev ua haujlwm ntawm Protein Gypsum Retarder

Protein gypsum retarders yog additives siv nyob rau hauv gypsum-raws li cov khoom, xws li gypsum plasters thiab gypsum board, kom ntev lub sij hawm teem ntawm cov khoom gypsum. Ntawm no yog saib ze dua ntawm kev ua haujlwm ntawm cov protein gypsum retarders:

1. Teem Lub Sijhawm Tswjhwm: Lub luag haujlwm tseem ceeb ntawm cov protein gypsum retarders yog ncua sijhawm los yog lub sijhawm hardening ntawm cov khoom siv gypsum. Gypsum ib txwm muaj cov tshuaj tiv thaiv nrog dej, hu ua hydration, uas ua rau tsim cov calcium sulfate dihydrate (gypsum). Cov txheej txheem hydration no ua rau cov khoom siv gypsum teeb thiab tawv rau hauv cov khoom hnyav. Los ntawm kev ntxiv cov protein gypsum retarders, lub sijhawm teem sijhawm ntawm gypsum tuaj yeem ua kom ntev, tso cai rau kev ua haujlwm ntev lossis sijhawm thov.
2. Ua haujlwm tau zoo: Protein gypsum retarders pab tswj kev ua haujlwm ntawm cov ntaub ntawv gypsum thaum siv. Los ntawm kev ncua sij hawm teem sijhawm, lawv muab sijhawm ntxiv rau kev sib xyaw, sib kis, thiab kho cov khoom siv gypsum ua ntej nws pib teeb. Qhov no txhim kho qhov yooj yim ntawm kev tuav thiab siv cov khoom siv gypsum, tshwj xeeb tshaj yog nyob rau hauv cov xwm txheej uas yuav tsum tau ua haujlwm ntev dua.
3. Kev Tswj Kev Cracking: Kev ncua sij hawm teem sijhawm ntawm gypsum tuaj yeem pab txo qis qhov tshwm sim ntawm kev tawg hauv cov khoom siv gypsum. Los ntawm kev tso cai rau ntau lub sij hawm rau cov khoom ntws thiab nyob rau hauv qhov chaw, protein gypsum retarders tuaj yeem pab txo qis kev ntxhov siab sab hauv thiab txhim kho tag nrho kev ncaj ncees ntawm gypsum qauv. Qhov no yog ib qho tseem ceeb tshwj xeeb tshaj yog nyob rau hauv cov ntawv thov uas tawg tuaj yeem cuam tshuam qhov kev ua tau zoo lossis cov tsos ntawm cov khoom tiav.
4. Kev tswj kub thiab av noo: Protein gypsum retarders tuaj yeem pab txo qhov cuam tshuam ntawm qhov kub thiab av noo ntawm lub sijhawm teeb tsa ntawm cov khoom siv gypsum. Nyob rau hauv ib puag ncig uas muaj qhov kub thiab av noo, gypsum tuaj yeem teem sijhawm sai dua, txo lub sijhawm ua haujlwm thiab muaj feem cuam tshuam rau cov khoom zoo. Los ntawm retarding lub sij hawm teem, cov protein gypsum retarders tso cai rau kev ua tau zoo ib yam thiab yooj yim dua daim ntawv thov nyob rau hauv txawv ib puag ncig tej yam kev mob.
5. Compatibility: Protein gypsum retarders yog feem ntau sib xws nrog lwm yam additives thiab cov khoom xyaw uas nquag siv nyob rau hauv gypsum formulations. Qhov no tso cai rau kom yooj yim koom ua ke rau hauv cov khoom gypsum yam tsis muaj kev cuam tshuam rau kev ua haujlwm lossis cov khoom. Nws yog ib qho tseem ceeb los xyuas kom meej qhov kev ntsuam xyuas sib raug zoo thaum tsim cov khoom siv gypsum kom ua tiav lub sij hawm xav tau thiab cov yam ntxwv ua haujlwm.

Hauv cov ntsiab lus, cov protein gypsum retarders ua haujlwm tseem ceeb hauv kev tswj lub sijhawm teeb tsa thiab txhim kho kev ua haujlwm ntawm cov khoom siv gypsum. Los ntawm kev ncua sij hawm teem sijhawm, lawv muab kev yooj yim dua rau hauv daim ntawv thov thiab pab ua kom zoo thiab ua haujlwm ntawm cov ntaub ntawv gypsum hauv ntau yam kev tsim kho thiab kev lag luam.
