Txoj kev tsim cov calcium formate yog ib feem ntawm kev tsim cov khoom siv tshuaj lom neeg. Calcium formate yog cov khoom siv organic uas siv dav. Tam sim no, cov txheej txheem tsim cov calcium formate uas twb muaj lawm raug kev txom nyem los ntawm cov nqi khoom siab thiab cov khoom tsis huv ntau dhau.
Cov thev naus laus zis no suav nrog kev sib xyaw ua ke ntawm formaldehyde, acetaldehyde, thiab calcium hydroxide hauv qhov sib piv molar ntawm 4.2 ~ 8: 1: 0.5 ~ 0.6, ua raws li kev sib xyaw ntxiv nrog formic acid. Cov txheej txheem yog raws li nram no: Acetaldehyde, formaldehyde, calcium hydroxide, thiab formic acid raug ntxiv rau hauv lub lauj kaub sib xyaw ua ke hauv qhov sib piv saum toj no rau kev sib xyaw, nrog rau qhov kub thiab txias tswj tau ntawm 16 ° C thiab 80 ° C, thiab lub sijhawm sib xyaw teeb tsa rau 1.5 ~ 4 teev. Tom qab kev sib xyaw, cov tshuaj tau kho kom tsis muaj zog. Cov tshuaj tau los ntawm kev sib xyaw siab, kev sib xyaw ua ke ntawm lub tshuab nqus tsev, thiab kev ziab centrifugal kom tsim cov calcium formate; cov kua txiv hmab txiv ntoo centrifugal tau rov qab los ua pentaerythritol.

Nrog tus nqi qis, ruaj khov siab, thiab ntau yam txiaj ntsig (los ntawm kev ua kom acidification mus rau kev tiv thaiv pwm), calcium formate yog koj cov khoom noj khoom haus zoo tagnrho. Npaj txhij kawm ntxiv? Hu rau peb hnub no!
