Ho kenyelletsa likhalase tse se nang letho lihlahisoa tsa rabara ho ka tlisa melemo e mengata:
1, Phokotso ea boima ba 'mele
Lihlahisoa tsa rabara le tsona li lebisa tlhokomelong e bobebe, e tšoarellang, haholo-holo ts'ebeliso e butsoitseng ea soles ea rabara ea li-microbeads, ho tloha ho tšubuhlellano e tloaelehileng ea 1.15g/cm³ kapa ho feta, eketsa likarolo tse 5-8 tsa li-microbeads, tse fokotsehileng ho 1.0g/cm³ (tseo hangata li tsejoang e le "floating holim'a metsi"), ho na le tekanyo e itseng ea bareki ka R & D 9bead kapa 9. esita le 0.85g / cm³, haholo ho fokotsa sets'oants'o sa rabara, lieta le boemo bo tšoanang pele ho fokotsa boima ba 20% kapa joalo. Hona joale, bareki ba bang ba nang le bokhoni bo itseng ba R & D ba tla etsa hore boima ba 0.9 kapa esita le 0.85g / cm³ ka ho eketsa li-microbeads, tse fokotsang haholo ho teteana ha rabara, 'me boima ba lieta bo tla fokotseha ka hoo e ka bang 20% ​​tlas'a boemo bo tšoanang le ba pele.
2, ho thibela mocheso
Sebopeho se sekoti sa lifaha tsa khalase se se nang letho se fa lifaha mocheso o tlase oa mocheso, joalo ka ha mochini o tlase oa mocheso oa mocheso o kenyellelitsoeng thepa ea rabara o ka bapala phello e ntle haholo ea ho kenya mocheso, joalo ka lipampiring tsa ho kenya mocheso, liboto tsa ho kenya mocheso le lihlahisoa tse ling tse sebelisoang.
3. Ho monya molumo le ho fokotsa lerata
Ka hare ho likhase tse sekoti tsa khalase ke khase e tšesaane, maqhubu a molumo karolong ena a tla fokola, ka tekanyo e itseng ea ho eketsa ho bapala phello e ntle haholo ea ho monya molumo le ho fokotsa lerata.
4, botsitso bo botle ba dimensional
Thepa ea motheo ea lifaha ke khalase e nang le coefficient e tlase ea katoloso ea mocheso, botsitso bo botle ba sebopeho ha e le tlas'a khatello ea mocheso, e kenyellelitsoeng ho thepa ea rabara e tla fa sehlahisoa botsitso bo betere ba dimensional.

Litlhahiso tsa ho sebelisoa ha ho etsoa:
1, lisebelisoa tsa ts'ebetso ea lihlahisoa tsa rabara hangata ke mochini o hloekisang, opener, single-screw extruder, joalo-joalo, hobane lifaha ke lerako la lisebelisoa tsa khalase ke tsa likaroloana tse thata, karolo ea matla a ho kuta a mochini a tla robeha hanyane, lifaha li tla lahleheloa ke ts'ebetso ea eona e ikhethang kamora ho robeha.
2, likhase tsa khalase tse se nang letho li na le mefuta e fapaneng le litekanyo tse lumellanang, ho latela lisebelisoa tse fapaneng le litlhoko tsa sehlahisoa ho khetha lihlahisoa tse nepahetseng tsa lifaha ke tsa bohlokoa haholo, St. Leite e khothaletsa tšebeliso ea HL38, HL42, HL50, HS38, HS42 lihlahisoa tsa rabara.
3, ha e sebelisoa mochine oa ho hloekisa, ho na le rotor holim'a sekoahelo sa thepa ea rabara, lifaha li ke ke tsa qojoa ka matla a ho kuta, ka hohle kamoo ho ka khonehang ho fokotsa nako ea lifaha nakong ea ho hloekisa, ho kgothaletswa ho eketsa ka morao ho hloekisa ho etsa bonnete ba hore lifaha tse kenyelletsoeng ho hloekisa 3-5min li ka qhalakanngoa ka mokhoa o ts'oanang; mochining oa ho hloekisa, ho arohana ha li-roller le nako ea ho hloekisa ea ho sithabela ha lifaha ho na le tšusumetso e kholoanyane, ho kgothaletswa hore sebaka sa marang-rang> 2mm, nako ea ho hloekisa ha ea lokela ho ba nako e telele haholo; Kakaretso ea matla a ho kuta a sekoti se le seng sa extruder se nyane, ha re bua, tšusumetso ho li-microbeads e nyane, ho kgothaletswa ho eketsa mocheso wa extrusion ka 5 ℃, ho fokotsa viscosity ea thepa ho thusa ho bopa extrusion, ho fokotsa li-microbeads tse robehileng.
