PVC SG-5 ho hlahisa phala
PVC SG-5 ho hlahisa phala,
PVC phala tlhahiso ea thepa e tala,
Ha ho etsoa li-tubes tse thata, resin ea SG-5 e nang le degree e tlase ea polymerization e lokela ho khethoa.Ha tekanyo ea polymerization e phahame, e ntlafatsa thepa ea eona ea 'mele le ea mechine le ho hanyetsa mocheso, empa metsi a fokolang a resin a tlisa mathata a itseng ho sebetsa, kahoo SG-5 resin e nang le viscosity ea (1.7 ~ 1.8) × 10-3Pa• s e khethoa ka kakaretso.
Peipi e thata ka kakaretso e sebelisa lead stabilizer, botsitso ba eona ba mocheso ke ntho e ntle, e sebelisoang khafetsa tribasic lead, empa lubrication ea eona e fokola, hangata le lubricity e ntle ea lead, sesepa sa barium.
Ts'ebetso ea li-tubes tse thata, khetho le tšebeliso ea mafura ke ea bohlokoa haholo, eseng feela ho nahana ka lubrication ea ka hare ho fokotsa matla a intermolecular, e le hore ho qhibiliha viscosity ho fokotseha ho loketseng ho theha, empa hape ho nahana ka lubrication e ka ntle, ho thibela ho qhibiliha. le ho khomarela tšepe e chesang, e le hore bokaholimo ba sehlahisoa bo khanye.
Sesepa sa tšepe hangata se sebelisoa bakeng sa ho tlotsa ka hare, 'me boka ba boka ba metsi bo tlaase bo sebelisetsoa ho tlotsa ka ntle.
Filler haholo-holo e sebelisa calcium carbonate le barium (barite phofo), calcium carbonate e etsa hore ts'ebetso ea holim'a phala e be ntle, barium e ka ntlafatsa sebopeho, e etsa hore phala e be bonolo ho e bōpa, ka bobeli e ka fokotsa litšenyehelo, empa chelete e ngata haholo e tla. ama ts'ebetso ea phala, phala ea khatello le phala e thibelang kutu ho molemo hore e se ke ea eketsa kapa ea eketsa tlatsetso e nyane.
Lihlahisoa tsa resin tsa PVC hangata ke phofo e tšoeu, calcium carbide SG-5 mofuta oa PVC resin K boleng ka 66-68, haholo-holo e sebelisetsoang phala ea extrusion, profil, bar, sheet le lihlahisoa tse ling tse thata tsa PVC, tekanyo ea polymerization hoo e ka bang 1000, molek'hule e kholo. boima.Lihlahisoa tse fapaneng tse thata, tse bonolo le tse bonaletsang li ka etsoa ka ho eketsa polasetiki e loketseng ka resin ea PVC.
Likoloi tse hloekileng le tse koahetsoeng li lokela ho sebelisoa ho thibela pula nakong ea lipalangoang tsa lihlahisoa.Polokelo, e lokela ho bolokoa sebakeng se ommeng, se nang le moea o motle oa polokelo.
