Calcium Formate, Npaj Txhij Rau Kev Xa Khoom ~

Daim Ntawv Thov:

1. Ua ib yam khoom noj tshiab. Kev pub calcium formate kom nce qhov hnyav thiab siv calcium formate ua ib yam khoom noj rau cov menyuam npua tuaj yeem ua rau cov menyuam npua noj mov ntau dua thiab txo qhov mob raws plab. Ntxiv 1% txog 1.5% calcium formate rau cov zaub mov menyuam npua tuaj yeem txhim kho kev ua tau zoo ntawm cov menyuam npua uas tsis tau noj mis. Kev tshawb fawb pom tias kev ntxiv 1.3% calcium formate rau cov zaub mov ntawm cov menyuam npua uas tsis tau noj mis tuaj yeem txhim kho qhov hloov pauv pub mis los ntawm 7% txog 8%, thiab ntxiv 0.9% tuaj yeem txo qhov tshwm sim ntawm mob raws plab hauv cov menyuam npua. Lwm yam uas yuav tsum nco ntsoov yog: kev siv calcium formate zoo ua ntej thiab tom qab tsis tau noj mis, vim tias cov kua qaub hydrochloric uas tus menyuam npua tso tawm nce ntxiv nrog hnub nyoog; calcium formate muaj 30% ntawm cov calcium uas yooj yim nqus tau, thiab yuav tsum tau ceev faj kom kho cov calcium thiab phosphorus thaum tsim cov khoom noj.

2. Siv rau hauv kev tsim kho. Siv ua tus neeg sawv cev sai, roj nplua nyeem thiab tus neeg sawv cev rau lub zog thaum ntxov rau cov cement. Siv rau hauv kev tsim cov mortars thiab ntau yam concretes kom ua kom cov cement tawv thiab luv lub sijhawm teeb tsa, tshwj xeeb tshaj yog thaum lub caij ntuj no kev tsim kho kom tsis txhob teeb tsa qeeb dhau ntawm qhov kub qis. Kev rhuav tshem yog sai, uas ua rau cov cement muaj zog ntxiv thiab siv tau sai li sai tau.

Calcium formate siv: ntau yam mortars qhuav sib xyaw, ntau yam concretes, cov ntaub ntawv hnav-resistant, kev lag luam hauv pem teb, kev lag luam pub tsiaj, tanning. Calcium formate koob tshuaj thiab kev ceev faj Cov koob tshuaj ib tuj ntawm cov mortar qhuav thiab concrete yog li 0.5 ~ 1.0%, thiab qhov ntau tshaj plaws ntxiv yog 2.5%. Cov koob tshuaj ntawm calcium formate maj mam nce ntxiv thaum qhov kub poob qis. Txawm tias yog 0.3-0.5% siv rau lub caij ntuj sov, nws yuav muaj cov txiaj ntsig zoo thaum ntxov.
