Cov nyhuv ntawm kev ntxiv calcium formate yog txawv
Txhua tus neeg ua haujlwm tsim kho paub tias caustic acid rov qab yog ib qho teeb meem ntawm cov khoom siv tridacidacin. Nyob rau hauv xyoo tas los no, txhawm rau txo cov teeb meem tshwm sim ntawm caustic acid rov qab, kev tsim kho kev lag luam tau siv cov pobzeb caulk rau cement. Raws li ib tug mortar thaum ntxov lub zog tus neeg saib xyuas, calcium formate yog dav siv vim nws cov yam ntxwv tshwj xeeb, uas yuav ua rau kom lub hardening tus nqi ntawm cement-raws li kev sib koom ua ke fillers thiab txhim kho lub zog thaum ntxov ntawm cement-raws li kev sib koom ua ke.
Cov khoom siv caulking tau muab faib ua cov khoom siv phab ntsa sab nraud thiab cov khoom siv phab ntsa sab hauv, thaum lub caustic rov qab feem ntau tshwm sim nyob rau hauv lub caij ntuj no kev tsim kho nyob rau hauv fogging hnub los yog sab nrauv phab ntsa tom qab kev tsim kho nyob rau hauv tsawg tshaj li 24 teev tom qab los nag tshwm ib feem dawb, thiab muaj cov khoom siv lead ua dawb los nag, uas cuam tshuam rau cov hniav zoo nkauj ntawm cov khoom lag luam caulking.
Feem ntau siv cov ntaub ntawv caulking yog: dawb cement, putty hmoov, caulking agent, sealant thiab lwm yam. Ntawm cov ntaub ntawv no, cov cement dawb thiab putty hmoov yog cov khoom siv caulking, tab sis ob qho tib si ntawm cov ntaub ntawv no tsis ua haujlwm. Daim ntawv thov ntawm calcium formate yog superior rau cov tsoos caulking cov ntaub ntawv,
Properties thiab xaiv cov calcium formate
Calcium formate yog cov khoom siv hmoov dawb, uas tuaj yeem ua kom cov hydration ntawm cov cement, yog li txhim kho lub zog thaum ntxov ntawm cov cement-based caulk, yog li ntxiv cov calcium uas tsim nyog rau lub caij ntuj no formulation ntawm cement-based caulk yuav tsum ua kom lub zog ntawm cov cement-based caulk. tsim ntawm CSH gel, yog li txo qhov tshwm sim ntawm rov qab alkali.
Kev tsim cov nplai alkali yuav tsis tsuas yog cuam tshuam los ntawm kev tsim kho ib puag ncig, ceramic pobzeb raws li lub hauv paus feem ntau yog lub hauv paus ntawm qhov teeb meem. Kev xaiv cov khoom tsim nyog calcium formate thiab ntau npaum li cas tseem ceeb heev los txhim kho cov khoom tiv thaiv alkali ntawm cov cement-raws li kev sib koom ua ke. Nyob rau lub caij ntuj no formulation system ntawm cement-raws li kev sib koom ua ke, 1-2% calcium formate cov ntsiab lus tuaj yeem txo qhov rov qab alkali ntawm cov cement-raws li kev sib koom ua ke.
