ntchito

Chifukwa pvc utomoni ali ndi thupi, mankhwala, magetsi, ntchito retardant lawi, m'ma 1930 ndi 40s, akunja anayamba kugwiritsa ntchito PVC zofewa monga kutchinjiriza za waya, chitukuko ndi kugwiritsa ntchito PVC chingwe chuma China anayamba mu 1950s.Ndi kusintha kwa mphamvu yopanga utomoni wa PVC, plasticizer ndi zowonjezera zamakampani komanso kukwezeleza ndi kugwiritsa ntchito mitundu yatsopano, makampani opanga zingwe ali ndi mbiri yabwino.

M'zaka za m'ma 1900, ndi kupititsa patsogolo kuzindikira kwa chilengedwe kwa anthu ndi chidwi cha anthu ku thanzi lawo, nkhani za chilengedwe zakhala zikuyang'ana kwambiri pamagulu a anthu.Maiko ambiri, zigawo ndi mabungwe apanga miyezo ndi malamulo okhwima kuti achepetse kugwiritsa ntchito zinthu zovulaza, makamaka malamulo a RolS ndi REACH.Kuyang'ana njira zatsopano ndi njira zatsopano, kusintha mlingo magwiritsidwe ntchito chuma, agwirizane ndi zofunika za malamulo chitetezo zachilengedwe ndi malamulo, chilengedwe chitetezo PVC chingwe zipangizo anatulukira pa nthawi, ndipo mwamsanga kukhala mmodzi wa mitu ya panopa PVC chingwe chitukuko zipangizo. .

Kusintha kochulukira komanso kukula kwa msika wama waya ndi chingwe (wotchedwa chingwe), komanso kafukufuku wozama wazowonjezera zatsopano (monga zowonjezera zoletsa moto, chopondereza utsi), kulimbikitsa kukwezedwa ndi kugwiritsa ntchito zatsopano. matekinoloje, zida zatsopano ndi zinthu zatsopano za PVC.Muzinthu zambiri zakuthupi (monga pulasitiki, mphira) zomwe zimagwiritsidwa ntchito pamakampani opanga zingwe, kuchuluka kwa chingwe cha PVC ndicho chinthu choyamba m'dziko lathu.

PVC chingwe zinthu wapangidwa polyvinyl kolorayidi utomoni, stabilizer, plasticizer, filler, lubricant, antioxidant, colorant ndi zina zotero.

Pulasitiki ya PVC chifukwa chakuyaka kwake, kukana kwamafuta, kukana kwa corona, kukana kwa dzimbiri kwamankhwala komanso kukana madzi abwino, chifukwa chake imagwiritsidwanso ntchito kwambiri ngati zinthu zoteteza mawaya ndi zingwe.Powonjezera zina zowonjezera magwiridwe antchito kapena zosintha, zosagwira kutentha (105 ℃), zosagwira kuzizira, zosagwira mafuta, zosagwira moto, zofewa kwambiri komanso zopanda poizoni za PVC zitha kupangidwa motsatana kuti zikwaniritse zosowa zamawaya apadera ndi chingwe.
