PVC utomoni WA CABLE
PVC utomoni WA CABLE,
PVC Cable Compound, PVC Cable Raw Material, PVC Kwa Waya Zamagetsi, PVC utomoni wa kutchinjiriza chingwe,
PVC chifukwa ali ndi thupi labwino, mankhwala, magetsi, lawi retardant ntchito, m'ma 1930 ndi 40s, akunja anayamba kugwiritsa ntchito PVC zofewa monga kutchinjiriza za waya, chitukuko ndi kugwiritsa ntchito PVC chingwe chuma m'dziko lathu 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.
Thermoplastic mkulu-maselo polima wopangidwa ndi kuyimitsidwa polymerization wa vinilu kolorayidi monoma.The molecular formula :- (CH2 – CHCl) n – (N: digiri ya polymerization, N= 590 ~ 1500).Ndizinthu zomwe zimagwiritsidwa ntchito kwambiri popanga pulasitiki.Ili ndi kukhazikika kwamankhwala abwino, kukana dzimbiri komanso kukana madzi.
