Blister tshuab tsim cov ntawv monomer vinyl chloride tsuas yog calcium carbide acetylene

Ua ntej xyoo 1960, kev tsim cov tshuaj monomeric vinyl chloride yog tsim los ntawm calcium carbide acetylene, vim tias calcium carbide ntau lawm yuav tsum muaj hluav taws xob ntau thiab coke, thiab tus nqi siab. Tom qab kev lag luam ntawm ethylene oxychlorination los tsim vinyl chloride nyob rau hauv thaum ntxov 1960s, lub teb chaws tig mus rau pheej yig dua roj av raws li raw cov ntaub ntawv. Tsis tas li ntawd, vim tias feem ntau ntawm cov khoom siv raw ntawm PVC (kwv yees li 57 feem pua ​​​​ntawm qhov hnyav) yog cov roj chlorine, ib qho khoom lag luam uas tsis tuaj yeem ntawm kev lag luam alkali ntau lawm, nws tsis yog tsuas yog nplua nuj nyob hauv cov khoom siv raw, tab sis kuj yog ib qho ntawm cov khoom lag luam. cov khoom tseem ceeb heev rau kev tsim kho chlor-alkali kev lag luam thiab ntsuas cov roj chlorine. Yog li ntawd, txawm hais tias qhov kev faib ua feem ntawm polyvinyl chloride hauv plastics tau poob qis, nws tseem tswj tau qhov kev loj hlob siab.
