Ukuqulunqwa kwezixhobo ezincedisayo zomgca wokuvelisa i-extruder

       Kukho iintlobo ezininzi zoomatshini abancedisayo be-extrusion kunye neengoma ezinzima. Iinkqubo ezahlukeneyo zenziwe ngezixhobo ezincedisayo ezahlukeneyo. Nangona kunjalo, oomatshini abancedisayo abahlukeneyo ngokubanzi baquka amakhonkco amahlanu asisiseko: ukubumba, ukupholisa, ukutsala, ukusika, kunye nokubopha (okanye ukupakisha). Ukongeza kuqwalaselo lwezixhobo ezihambelanayo ngokwala makhonkco mahlanu asisiseko, ezinye iindlela okanye izixhobo ziqwalaselwe ngokweemfuno ezithile zeemveliso ezahlukeneyo, ezifana nezixhobo zohlengahlengiso loxinzelelo lwefilimu okanye koomatshini abancedisa intambo, izixhobo zokufudumeza ngaphambi kokugquma, ububanzi bombhobho okanye ifilimu. Ubukhulu Isixhobo sokulawula ingxelo ezenzekelayo, njl.

Ngokwendlela yokufumana imilo kunye nobukhulu beemveliso ezikhutshiweyo, iplastiki yokubumba oomatshini abancedisayo inokwahlulwa ibe ngamacandelo amathathu alandelayo.

(1) Oomatshini abancedisayo be-extrusion baqulunqwa yintloko yomatshini ukunika ubungakanani kunye nokumila kwemveliso kwaye emva koko ipholile kwaye imile ukuze ifumane imveliso ngokuthe ngqo, kubandakanywa noomatshini abancedisayo be-extrusion njengegranulation, imibhobho, iipleyiti (amaphepha), ekhethekileyo. iiprofayili, kunye nocingo kunye neentambo zokugquma. .

(2) Umatshini oncedisayo we-extrusion kunye nokwelula ukubumba kukwelula i-parison eyenziwe yintloko yomatshini ukuya kwinqanaba elikhulu (i-unidirectional okanye i-bidirectional stretching), kwaye usebenzise imilo eyoluliweyo kunye nobukhulu njengemilo kunye nobukhulu bemveliso, kubandakanywa neefilimu. , Ukwenza oomatshini abancedisayo njenge-monofilament, ifilimu ejoliswe kwi-biaxially, i-foam sheet, i-tape yokupakisha, ifilimu yokukrazula kunye ne-mesh.

(3) Iyunithi yokubumba i-Extrusion: I-blank yenziwe yintloko yomatshini, kwaye ukubunjwa kokugqibela kufezekiswa ngokusebenzisa isixhobo sokubumba, kubandakanywa ukubumba okungenanto (okufana neebhotile zeplastiki), i-bellows kunye nabanye oomatshini abancedisayo bokubumba.
