Intshayelelo ye-extruder yerabha
I-extruder yerabha sisixhobo esisisiseko kushishino lwerabha kwaye sesinye sezixhobo eziphambili ezichaphazela umgangatho wemveliso. Idlala indima ebaluleke kakhulu kwinkqubo yokuvelisa amatayara kunye neemveliso zerabha. Uphuhliso lwe-extruder yerabha yangaphandle luye lwaba ne-Plug extruder, i-screw type hot feed extruder, i-common cold feed extruder, i-main kunye ne-assistive screw thread cold extruder, i-cold feed exhaust extruder, i-pin cold feed extruder, i-Compound extruder kunye nezinye izigaba. I-extruder yerabha isetyenziselwa ukucinezela, ukucoca kunye nokufaka iimveliso zerabha ze-semi-products. Iimpawu zesakhiwo: I-screw kunye ne-inner sleeve zenziwe ngentsimbi ye-nitrided, enokumelana nokuguguleka okuhle kunye nokumelana nokugqwala.
Ukukhupha irabha nge-screw extrusion eyenziwe nge-rubber extruder yenye yezona ndawo zindala zobuchwepheshe bokukhupha irabha, ezinokulandelwa emva kwinkulungwane ye-19. Ii-rubber extruders zahluke kakhulu kwii-thermoplastic extruders. Okokuqala, ukukhupha irabha kwenziwa kumaqondo obushushu aphantsi (ukuya kuthi ga kwi-130°C). Okwesibini, ukukhupha irabha kudla ngokubandakanya imicu (kwaye kuphela kwiimeko ezingaqhelekanga, ii-pellets), ezingatshintshiyo ngokwesigaba kwinkqubo ye-screw extruder okanye iqondo elikhulu lokutyeba. Ngokungafaniyo nee-thermoplastics, ii-thermoplastics zicutshungulwa kumaqondo obushushu angama-180^-300°C (okanye ngaphezulu) kwi-screw extruder, kwaye amasuntswana aqinileyo aphantsi adla ngokufakwa kwi-extruder. Xa ii-pellets zihamba phambili nge-screw, umthombo otyhidiweyo uyaqiniswa.
Ii-extruder zerabha zihlala zihlelwa njengoomatshini bokutya okushushu kunye noomatshini bokutya okubandayo. Kwii-extruder zerabha ezishushu, i-compound yerabha ifudunyezwa yintshukumo yomatshini ye-open mill, kwaye ezi strips zishushu ziyasikwa kwaye zikhutshwe rhoqo. Ukutya kumatshini. Kwi-cold feed screw extruder, umcu werabha wobushushu begumbi wongezwa kwi-extruder. I-raber extruder ikwahlelwa ngokwendlela yokuba isetyenziselwa ukukhupha umoya okanye hayi.
Iintlobo zee-Extruders zerabha
I-extruder yerabha sisixhobo esisisiseko kushishino lwerabha kwaye sesinye sezixhobo eziphambili ezichaphazela umgangatho wemveliso. Idlala indima ebaluleke kakhulu kwinkqubo yokuvelisa amatayara kunye neemveliso zerabha. Uphuhliso lwe-extruder yerabha yangaphandle luye lwadlula kwi-column Plug extruder, i-screw type hot feed extruder, i-common cold feed extruder, i-main kunye ne-assistive screw thread cold feed extruder, i-cold feed exhaust extruder, i-pin cold feed extruder, i-Compound extruder kunye nezinye izigaba.
I-extruder yerabha yahlulwe yaba: uhlobo lwe-plunger, uhlobo lwe-screw, uhlobo oluqhelekileyo, uhlobo lokutya olubandayo, uhlobo lwe-pin, uhlobo lwe-compound. Ithrendi yophuhliso lwexesha elizayo: inkqubo entsha yokulawula idrayivu ene-multi-screw ezininzi ezine-multi-compound ubuchwepheshe obuchanekileyo
