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 li boetse li lebisa tlhokomelong e bobebe, e tšoarellang, haholo-holo ts'ebeliso e butsoitseng ea li-microbeads tsa rabara, ho tloha ho tšubuhlellano e tloaelehileng ea 1.15g/cm³ kapa ho feta, eketsa likarolo tse 5-8 tsa li-microbeads, tse fokolitsoeng ho 1.0g/cm³ (tseo hangata li tsejoang e le " e phaphametseng holim'a metsi"), ho na le tekanyo e itseng ea bokhoni ba bareki ba R & D ka ho eketsa li-microbeads e tla ba boima ba 0.9 kapa esita le 0.85g / cm³, ho fokotsa haholo boima ba rabara, lieta le boemo bo tšoanang pele ho fokotsa boima ba 'mele. 20% kapa ho feta.Hona joale, bareki ba bang ba nang le bokhoni bo itseng ba R & D ba tla etsa hore boima bo be 0.9 kapa esita le 0.85g / cm³ ka ho eketsa li-microbeads, tse fokotsang haholo boima ba rabara, 'me boima ba lieta bo tla fokotseha ka hoo e ka bang 20% ​​tlas'a eona. boemo joalo ka pele.
2, ho thibela mocheso
Sebopeho se sekoti sa likhase tsa khalase se se nang letho se fa lifaha boemo bo tlase ba mocheso, joalo ka ha mochini o tlase 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 karolo ea likaroloana tse thata, karolo ea matla a ho kuta a mochini a tla robeha hanyane, lifaha li tla lahleheloa. tshebetso ea eona e ikhethang ka mor'a ho robeha.
2, likhase tsa khalase tse se nang letho li na le mefuta e fapaneng le li-parameter 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 ke matla a ho kuta, ka hohle kamoo ho ka khonehang ho fokotsa nako ea lifaha ho hloekisa, ho kgothaletswa ho eketsa ho hloekisoa ha morao ho netefatsa hore lifaha tse kentsoeng ho hloekisoa 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. robehile.
