Kev siv Calcium Formate

Kev lag luam kev tsim kho

Calcium formate feem ntau yog siv hauv kev tsim kho kev lag luam ua ib qho ntxiv hauv pob zeb thiab cement. Nws yog siv los ua ib qho chaw accelerator, uas ua rau kom qhov chaw thiab cov txheej txheem hardening ntawm pob zeb. Calcium formate kuj tseem siv tau los ua cov dej txo qis, uas txhim kho kev ua haujlwm ntawm pob zeb los ntawm kev txo cov dej uas xav tau rau kev sib tov. Tsis tas li ntawd, calcium formate yog siv los ua cov tshuaj tiv thaiv corrosion, uas pab tiv thaiv cov hlau thiab lwm yam hlau los ntawm corrosion.

Tsiaj Pub

Calcium formate kuj tseem siv rau hauv cov tsiaj pub noj raws li kev khaws cia thiab qhov chaw ntawm calcium. Nws yog ntxiv rau pub kom tiv thaiv kev loj hlob ntawm cov kab mob tsis zoo thiab txhim kho lub txee lub neej ntawm pub. Calcium formate kuj yog qhov zoo ntawm calcium rau cov tsiaj, uas yog qhov tseem ceeb rau cov pob txha thiab cov hniav.

Tawv Kev Lag Luam

Calcium formate yog siv hauv kev lag luam tawv nqaij ua tus neeg sawv cev tanning. Nws pab khaws cia cov hides thiab tiv thaiv lawv los ntawm rotting. Calcium formate kuj tseem siv los ua ib qho tsis nyob hauv cov txheej txheem tanning, uas pab tswj cov pH ntawm tawv.

Kev lag luam zaub mov

Calcium formate yog siv nyob rau hauv kev lag luam khoom noj khoom haus raws li cov khoom noj additive. Nws tau ntxiv rau qee yam khoom noj los txhim kho lawv cov tsw thiab tiv thaiv kev lwj. Calcium formate kuj tseem siv los ua cov khoom noj khoom haus, uas pab ua kom lub neej txee ntawm cov khoom noj.

Lwm Daim Ntawv Thov
