In 1797, Joseph Bramah patented txheej txheem extrusion uas yog thawj zaug tsim rau kev tsim cov kav hlau lead. Nws cov txheej txheem koom nrog preheating hlau thiab manually yuam nws los ntawm ib tug tuag nrog ib tug tes-tsav plunger.
Thaum twg yog extrusion thawj zaug?
Ntau cov duab uas koj pom ua los ntawm cov hlau tau txais txoj hauv kev hu ua hlau extrusion. Thawj txheej txheem extrusion rau yeeb nkab ua tau patented los ntawm Joseph Bramah nyob rau hauv 1797 Nws ua cov yeeb nkab tawm ntawm cov hlau mos raug yuam los ntawm kev tuag nrog kev siv lub tes tsav plunger.
Leej twg tsim lub extruder?
Xyoo 1820, Thomas Hancock tau tsim cov roj hmab "masticator" tsim los rov ua cov khoom siv roj hmab rov qab, thiab xyoo 1836 Edwin Chaffee tau tsim lub tshuab ob-cov menyuam los sib xyaw cov khoom siv roj hmab. Thawj qhov thermoplastic extrusion yog xyoo 1935 los ntawm Paul Troester thiab nws tus poj niam Ashley Gershoff hauv Hamburg, Lub Tebchaws Yelemees.
hnub nyoog pes tsawg tus extrusion?
In 1797 txheej txheem extrusion tau patented los ntawm tus neeg tsim khoom Joseph Bramah. Nws siv nws los ua cov kav dej txhuas thiab cov tshuab ua cov phom sij (Patent No. 2652). Tom qab ua ntej cua sov cov hlau nws siv tes tsav lub plunger los yuam kom nws tuag.
extruders ua dab tsi?
Extruders yog siv los tsim cov khoom txuas mus ntev xws li tubing, log tsheb treads, thiab hlau npog. Lawv kuj tseem siv los tsim ntau yam profiles uas tuaj yeem txiav kom ntev.
