PVC ke e 'ngoe ea lisebelisoa tse hlano tsa resin ea bokahohleng, e nang le litšobotsi tse ntle tse kang acid le alkali resistance, wear resistance, flame retardancy, le insulation. Hona joale, e fetohile sehlahisoa sa bobeli se seholo ka ho fetisisa sa polasetiki lefatšeng ka mor'a polyethylene.
1.Bokhoni ba tlhahiso ea malapeng le tlhahiso ea PVC
Ts'ebetso ea tlhahiso ea PVC haholo-holo e kenyelletsa litsela tse peli: mokhoa oa calcium carbide le mokhoa oa ethylene, 'me phapang e kholo ke mokhoa oa ho lokisetsa vinyl chloride monomer.
Ho ea ka pono ea tlhahiso lilemong tsa morao tjena, tlhahiso ea PVC e bontšitse mokhoa o ntseng o eketseha selemo le selemo, 'me matla a tlhahiso ea indasteri eohle a kene ka mokhoa o utloahalang oa tsoelo-pele. Tlhokahalo ea 'maraka e tsoetse pele butle-butle,' me tlhahiso e ntse e eketseha butle-butle. Ho latela data e tsoang ho China Chloroalkali Network, sekhahla sa ts'ebetso ea indasteri ea PVC ea China e ntse e le kaholimo ho 50% lilemong tsa morao tjena.
2. Mokhoa oa Ntlafatso oa Indasteri ea PVC
(1) Matlafatsa kaho ea lisebelisoa tsa ho kopanya indasteri
Ho tloha 2007, naha e thehile letoto la melaoana e fanang ka melaoana e qaqileng bakeng sa nts'etsopele ea indasteri ea PVC. Ka nako e ts'oanang, e khothaletsa kaho ea lisebelisoa tse tšehetsang lik'hamphani tsa tlhahiso ea calcium carbide le chlor alkali, le ho matlafatsa kaho ea lisebelisoa tsa ho kopanya indasteri. Tlas’a tataiso ea maano a hajoale a naha, ho thehoa ha lisebelisoa tsa ho kopanya liindasteri ho fetohile mokhoa o ke keng oa qojoa libakeng tse bohareng le tse ka bophirimela tsa Chaena, tse ruileng ka mashala, merafo ea letsoai le mehloli ea majoe a mokoetla. Tlas'a karolo ea lisebelisoa tse kopantsoeng, ka ho itšetleha ka melemo e mengata ea lisebelisoa le melemo e ts'oanang, litšenyehelo tsa tlhahiso li ka laoloa ka katleho 'me lihlahisoa tse fapa-fapaneng li ka sebelisoa hape, Ho ntlafatsa tlhōlisano ea' maraka le bokhoni ba ho phela ba khoebo.
(2) Mekhoa e fapaneng ea tlhahiso
Nts'etsopele ea hajoale ea likhoebo tsa lapeng tsa PVC, ho hatelloa ha mefuta e fapaneng ea lits'ebetso tsa lisebelisoa tsa tlhahiso e ntse e eketseha, e leng se etsang hore litlhoko tsa bona tsa boemo ba theknoloji li phahame haholo. Mokgwa wa ho fapafapana ha tshebetso ha o emise. Ka nts'etsopele e tsoelang pele ea mekhoa ea tlhahiso ea PVC ea malapeng, likhoebo li hloka ho sebelisa butle-butle mekhoa e mecha ea tlhahiso ha li ntse li boloka ts'ebetso ea pele ea calcium carbide. Ka nako e ts'oanang, theknoloji ea polymerization ea PVC le eona e tla ntlafatsoa haholo, haholo-holo mabapi le matla a tlhahiso ea li-polymerization reactors. Ntle le moo, hoa hlokahala ho kenyelletsa ka mafolofolo mahlale a tsoetseng pele a tlhahiso ea kantle ho naha le ho a khothaletsa butle-butle ho ntlafatsa katleho ea moruo oa indasteri.
