Yuav ua li cas rov qab cement puag caulk alkalinity? Cov nyhuv ntawm kev ntxiv calcium formate yog txawv?

Cov neeg ua haujlwm tsim kho paub tias kev xa rov qab yog qhov teeb meem tshwm sim hauv cov khoom siv silicate. Nyob rau hauv xyoo tas los no, txhawm rau txo qhov tshwm sim ntawm qhov teeb meem no, kev tsim kho kev lag luam tau siv cov pobzeb ceramic caulk los siv rau cov 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, thiab cov khoom caustic rov qab feem ntau tshwm sim nyob rau lub caij ntuj no pos huab-hnub siv los yog sab nrauv phab ntsa tom qab tsawg dua 24 teev tom qab kev tsim kho, lub zos whitening thiab dawb crystal cov ntaub ntawv los nag, uas cuam tshuam rau cov hniav zoo nkauj ntawm cov khoom 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 nrog cov mis molecular C2H2Ca04, uas tuaj yeem ua kom cov dej ntws ntawm cov cement, yog li txhim kho lub zog thaum ntxov ntawm cov cement-raws li caulk, yog li ntxiv cov nqi tsim nyog.calcium formatemus rau lub caij ntuj no formulation ntawm cov cement-raws li caulk yuav tsum ceev cov 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 siv calcium uas tsim nyog thiab ntau npaum li cas yog qhov tseem ceeb heev los txhim kho cov khoom tiv thaiv alkali ntawm cov khoom siv cement-based. Nyob rau hauv lub caij ntuj no formulation system ntawm cement-raws li kev sib koom ua ke muab tub lim, 1-2% calcium formate cov ntsiab lus tuaj yeem txo qhov rov qab alkali ntawm cement-raws li kev sib koom ua ke.
