Lisebelisoa tse ncha bakeng sa lisebelisoa tsa polasetiki

Phepelo ea PVC e fetolang li-YMs - lihlahisoa tsa lethathamo ke k'hamphani e tla ba theknoloji e tsoetseng pele ea polima le tsinghua lefapha la univesithi la bai cheng lik'hemik'hale tsa boenjineri ba theknoloji ea nano, kopanyo ea lipatlisiso le nts'etsopele ea mofuta o mocha oa PVC e sebetsanang le AIDS, e e sebelisa ka botlalo ea lisebelisoa tsa nanometer e kholo ho feta bokaholimo, litšobotsi tsa matla a mahala a maholo li kholo, ho hlola ts'ehetso ea moetlo oa ho lokisa PVC bothateng ba ts'ebetso ea polasetiki ka phapang e tlase ea mocheso. Ts'ebetsong ea ts'ebetso, tsitsipano e matla ea li-nanomaterials e fetoloa khohlano ea kahare le limolek'hule tsa PVC, hobane khohlano ena ea kahare e eketseha ka ho fokotseha ha mocheso, e leng ho ntlafatsang bothata ba hore polasetiki ea ACR ea setso e senyeha haholo ka ho fokotseha ha mocheso.
Ha li bapisoa le ACR ea setso, lihlahisoa tsa HLN - li na le litšobotsi tse latelang:
1) botsitso ee sa fetoleng boemo o molemo ho feta ba thusang ba setso sebetsa.
2) Ha mocheso o fetoha, matla a ho kuta a fetoha ka tsela e lumellanang, e ka etsang hore degree ea plasticization ea PVC e se fetohe.
3) e ka ntlafatsa ts'ebetso ea ts'ebetso ea PVC, ea ntlafatsa lihlahisoa tsa lihlahisoa. Method1 Mokhoa oa tlhahlobo
1) Tlhahlobo ea ponahalo ea pono
2) Volatile e ile ea metoa ho latela GB / T2914
3) Boholo ba phatsa bo ne bo lekantsoe ho latela GB / 2916
4) Machinability e ka lekanyetsoa ke RM-200 torque rheometer, lebelo ke 35rpm, mocheso ke 165oC, 'me palo ea phepo ke 61g;
Morero oa tlhahlobo ea tšebetso: PVC, 100g; CaCO3, 5 g; TiO2, 4 g; PE, 0,15 g; Asiti ea stearic, 0.2g; Letsoai, 2.5g; Motsoako o thata, 1.5g; K'halsiamo e thata, 0.7g; CPE, 9 g; Thuso ea ho sebetsana, 2g.
Process2 Ho sebetsana le thepa ea ho sebetsana le AIDS
Ts'ebetso ea moemeli oa PVC ke ho eketsa limolek'hule tsa kahare tsa motsoako le khohlano lipakeng tsa motsoako le sekontiri, bokaholimo ba silinda, e le ho ntlafatsa sejoale-joale le torque ea lisebelisoa tsa ts'ebetso ea PVC, PVC mochesong o tlase ka ho fetesisa o ka khonehang oa ho sebetsa. Hore o fumane tekanyo e tlaase ka ho fetisisa ea ho bola, ponahalo le thepa ea mochini oa lihlahisoa tse thata tsa PVC. Haeba mocheso oa ts'ebetso oa PVC o fokotsehile, palo e setseng ea botsitso ea lihlahisoa tsa PVC, e theola palo ea HCI, 'me e ntlafatsa botsitso kapa ho hanyetsa boemo ba leholimo ba lihlahisoa! Le boemo ba sebetsa tlaase mocheso ke ho etsa bonnete ba kuta phahameng, ke hore, lokela ho etsa bonnete ba phahameng hona joale le torque. Ka hona, ts'ebetso ea PVC e sebetsana le AIDS e tlameha ho hlahlojoa ka torque le ea hajoale, 'me lisebelisoa tsa tlhahlobo tse ka bonang torque ke torque rheometer, ka hona k'hamphani e fumanehang index ea boleng ba HLN - letoto la lihlahisoa, eseng ka viscosity empa le rheometer. ho khetholla ts'ebetso ea ts'ebetso ea ts'ebetso ea AIDS. Lihlahisoa tsohle li lekoa ka rheometer pele li tloha fekthering. Haeba li-curve tsa rheometer li lumellana, ts'ebetso ea ts'ebetso ea lihlahisoa tse peli tsa lihlahisoa e ts'oana, ho netefatsa botsitso ba bareki nakong ea tlhahiso le ts'ebeliso.
