ACR, thuso ea ho sebetsa ea PVC, e na le litekanyetso tse nyane empa e na le phello e kholo. Na u tseba?

Ho latela mekhahlelo, lithuso tsa ho sebetsa tsa PVC ACR li ka aroloa ka mekhahlelo e meraro:

1. Lisebelisoa tsa ho sebetsa tse khothalletsang polasetiki: Mofuta ona oa thuso ea ho sebetsa o sebelisoa haholo lihlahisoa tse thata tsa PVC. Mosebetsi oa eona o ka sehloohong ke ho khothaletsa polasetiki, ho ntlafatsa thepa ea rheological ea ho qhibiliha le ho ntlafatsa ho hasana ha li-additives tse ling, le ho ntlafatsa boleng bo bonahalang ba sehlahisoa.

E loketse lihlahisoa tse ngata tsa PVC tse kang profiles, liphaephe, lipoleiti (rola), joalo-joalo, tekanyo ea litšupiso ke 1-2phr.

2. Foaming regulator: Ka lebaka la boima ba eona bo phahameng ba limolek'hule, PVC foaming regulator e ka eketsa haholo matla a ho qhibiliha a thepa ea PVC, ka tsela eo ka katleho e phuthela khase e phophomang le ho etsa sebopeho sa khekhe ea linotši ho thibela khase hore e se ke ea baleha. PVC e foaming regulator e boetse e na le molemo ho hasanya lisebelisoa tse ling ho kenyelletsa le lisebelisoa tse phophomang, ho ntlafatsa boleng ba lihlahisoa le ho eketsa khanya.

E loketse maqephe a foamed, lithupa tse foamed, liphaephe tse foamed, profiles foamed, foamed wood plastic, etc. Tekanyetso ea litšupiso ke 4-8phr.

3. Thuso ea ho sebetsa ka ntle ho lubricating: E ​​na le thepa e tšoanang e ntle ea ho hlobolisa tšepe joalo ka boka ba polyethylene e nang le oxidized. Phapang ke hore e lumellana hantle le PVC. Ho isa bohōleng bo itseng, e ka eketsa ts'ebetso ea ho etsa polasetiki le ho ntlafatsa ho qhibiliha. Thepa ea Rheological, le katoloso ea phallo e lula e sa fetohe nakong ea ts'ebetso ea extrusion, ha e fetole thepa ea thermoforming, hape e thibela phello ea moholi e bakoang ke ho na ha lubricant lihlahisoa tse pepeneneng.

E loketse liforomo kapa lisebelisoa tse nang le litlhoko tse phahameng tsa ho sebetsa, haholo-holo lipampiri tse pepeneneng, li-profiles tsa foam, mapolanka a foam le polasetiki ea lehong e nang le foamed, joalo-joalo Tekanyetso ea litšupiso 0.5-2phr

Ka ho khetheha ts'ebetsong le lihlahisoa, ho qhibiliha ho qhibiliha ho ka ntlafatsoa nakong ea calendering, ho lumella thepa e setseng hore e tsamaee hantle pakeng tsa li-roller tse peli; boleng bo bonahalang bo ka ntlafatsoa nakong ea extrusion ea pipe, ho felisa ketsahalo ea "letlalo la shaka", le ho eketsa sekhahla sa extrusion; Nakong ea extrusion e hlakileng, palo ea "mahlo a litlhapi" ka sehlahisoa e ka fokotseha haholo; nakong ea ente e entsoeng, ho qhibiliha hoa eketseha, ka hona ho fokotsa molumo oa ente, ho fokotsa ts'ebetso ea "mela e tšoeu", ho eketsa khanya ea holim'a metsi, le ho ntlafatsa matla a ho tjheseletsa. Haeba lubricity e eketsoa Lithuso tsa ho sebetsa li ka ntlafatsa ts'ebetso ea ho theola, ho potlakisa potoloho ea ente le ho eketsa tlhahiso, le ho thibela ketsahalo ea "bloom" e bakoang ke ho thella ka ntle; nakong ea ho phunya, ba ka ntlafatsa polasetiki, ba fokotsa liketsahalo tsa fisheye, ba ntlafatsa elasticity ea ho qhibiliha, 'me ba etsa hore Botenya ba ho bopa bo be bo lekanang haholoanyane.
