Sefepi sa Rubber/ Sefepi sa Rabara
Khetho ea Sesefa sa Rubber
1. Filter ea rabara ea khatello - E loketse motsoako oa rabara o bonolo o sa hlokeng remix.
Tšobotsi: e bonolo ho e hloekisa, e ka fetisoa ka filthara ea li-mush tse 200, tlhahiso e kholoanyane.
2. Filter ea rabara ea Screw - E loketse mefuta eohle ea motsoako oa rabara bakeng sa indasteri ea li-roller.
Tšobotsi: mefuta e mengata ea rabara e ka hloekisoa.
1) Mofuta o le mong oa screw:
Mofuta o le mong o tloaelehileng oa screw - E loketse motsoako pakeng tsa 25-95Sh-A, empa eseng bakeng sa rabara e phahameng ea viscosity, joalo ka silicon joalo-joalo.
Qobella ho fepa mofuta o le mong oa screw - E loketse mefuta eohle ea motsoako oa rabara pakeng tsa 25-95Sh-A, esita le bakeng sa rabara e phahameng ea viscosity, e kang silicon, EPDM, Hypalon, joalo-joalo.
2) Mofuta oa li-screw tse peli:
Qobella ho fepa mefuta e 'meli ea li-screw - E loketse mefuta eohle ea motsoako oa rabara pakeng tsa 25-95Sh-A, esita le bakeng sa rabara e phahameng ea viscosity, e kang silicon, EPDM, Hypalon, joalo-joalo.
Qobella ho fepa ka li-screw tse peli ka mofuta oa TCU - E loketse motsoako pakeng tsa 25-100Sh-A, haholo-holo e loketseng motsoako o nang le mocheso.

Khetho ea Length-Diameter Ratio:
1. Haeba ho na le lehlabathe ka har'a rabara, karolelano ea bolelele-diameter ea screw e lokela ho khethoa bakeng sa e kholoanyane.
2. Molemo oa tekanyo e kholo ea bolelele ba bophara ba sekoti ke hore karolo e sebetsang ea screw e telele, thepa ea polasetiki e entsoe ka polasetiki, ho kopanya ho tšoana, rabara e tlas'a khatello e phahameng le boleng ba sehlahisoa se setle. Leha ho le joalo, haeba screw e le telele, e tla etsa hore rabara e chese habonolo, 'me ho sebetsa ha screw ho thata,' me matla a extrusion a eketseha.
3. Sekurufu se sebelisoang bakeng sa mochini oa rabara ea fepelo e chesang ka kakaretso se nka tekanyo ea bolelele ba bophara ba makhetlo a 4 ho isa ho a 6, 'me sekurufu sa mochini oa rabara oa fepelo o batang hangata se nka tekanyo ea bophara ba makhetlo a 8 ho isa ho a 12.
Melemo ea ho eketsa karo-karolelano ea bolelele ba bophara
1) Sekoti se hatelloa ka botlalo, 'me thepa ea' mele le ea mochini ea lihlahisoa e ka ntlafatsoa.
2) Plastiki e ntle ea lisebelisoa le ponahalo e ntle ea boleng ba lihlahisoa.
3) Eketsa molumo oa extrusion ka 20-40%. Ka nako e ts'oanang, sebopeho sa sekoti se nang le karo-karolelano e kholo ea bolelele ba bophara se na le moepa o tlase, o batlang o bataletse, 'me molumo oa extrusion o tsitsitseng.
4) E ntle bakeng sa ho bopa phofo, joalo ka PVC phofo extrusion tube.
Mathata a ho eketsa bolelele ba bophara ba karo-karolelano:
Ho eketseha ha bolelele-diameter karo-karolelano ho etsa hore ho be thata ho etsa screw le kopano ea screw le barrel. Ka hona, karolelano ea bolelele-diameter e ke ke ea eketseha ntle le moeli.
Litšebeletso
1. Ts'ebeletso ea ho kenya.
2. Tšebeletso ea tlhokomelo.
3. Tšehetso ea tekheniki tšebeletso ea inthaneteng e fanoeng.
4. Tšebeletso ea lifaele tsa tekheniki e fanoeng.
5. Ho fanoa ka litšebeletso tsa koetliso setšeng.
6. Ho fanoe ka litšebeletso tsa ho fetola le ho lokisa likarolo tse ling.
