Txhawm rau txheeb xyuas qhov hloov ib qho ntsia hlau, xa plaub pawg ntawm cov ntaub ntawv: tshuab thiab cov ntsiab lus sib txuas, cov ntaub ntawv tswj qhov ntev, cov khoom ua tiav thiab cov dej num ua haujlwm, thiab qhov yuav tsum tau lees paub meej. Ib qho piv txwv hnav pab, tab sis nws yog pov thawj ntawm ob qho tib si thawj tsim thiab kev puas tsuaj tom qab. Lub Hoobkas yuav tsum paub qhov txawv ntawm ob qho ua ntej pom zoo rau kev kos duab.

Cov txheej txheem tsim cov ntsia hlau thiab lub thoob feem ntau suav nrog kev tshuaj xyuas, cov khoom siv thiab kev xaiv ntawm qhov chaw, kev npaj dawb huv, kev ua haujlwm ntxhib thiab ua tiav, kev kho cua sov lossis hardfacing, kev ua tiav tiav, kev tshuaj xyuas qhov ntev thiab kev tiv thaiv ntim. Qhov kev txiav txim tsis yog universal. Nws yuav tsum tau npaj nyob ib ncig ntawm lub geometry, kev kho mob thiab qhov kawg qhov ntev ntawm qhov tshwj xeeb.

Ib qho kev sib txuas ntxaib ntsia hlau extruder muaj ob qhov txuas txuas txuas txuas txuas txuas ua ke ua los ntawm cov khoom siv modular. Feem ntau yog co-rotating, khiav ntawm kev kub ceev rau intensive mixing - uas ua rau lawv tus qauv tshuab rau compounding, masterbatch, WPC thiab pelletizing. Tsis zoo li lub tshuab conical, cov ntsia hlau profile tuaj yeem rov tsim dua rau txhua qhov kev tsim tshiab.

Ib lub taub hau ib lub taub hau yog ib lub hau ntswj rotating nyob rau hauv ib lub cylindrical chim, conveying, melting thiab pumping yas los ntawm ib tug tuag. Kev ua tau zoo yog tsim los ntawm peb yam: L / D ratio, compression ratio thiab ntsia hlau hom (tus qauv, barrier lossis sib tov). Nws yog qhov kev xaiv pheej yig tshaj plaws rau kev tso tawm siab extrusion ntawm cov khoom sib xws - zaj duab xis tshuab, yeeb nkab los ntawm pellets, ntawv thiab granulation.

Ib tug ntxaib ntsia hlau extruder siv ob lub intermeshing screws nyob rau hauv ib tug ntxaib-bore chim rau pub, yaj, sib tov thiab twj tso kua mis yas los ntawm ib tug tuag. Ob tsev neeg tseem ceeb yog conical (tapered screws, zoo tshaj plaws rau ncaj qha PVC yeeb nkab, profile thiab board extrusion) thiab parallel (constant-inch, segmented screws, zoo tshaj plaws rau compounding, granulation thiab high-filler mixing).

Ib tug sib npaug ntxaib ntsia hlau chim muaj ob intermeshing screws ntawm tas mus li txoj kab uas hla khiav ntawm ib sab nyob rau hauv ib tug sib tw ntxaib-bore chim. Tsis zoo li lub conical chim, cov ntsia hlau nyob rau tib qhov loj kawg mus rau qhov kawg, thiab lub thoob feem ntau yog tsim los ntawm ntu. Co-rotating parallel screws haum compounding, granulation thiab masterbatch; counter-rotating parallel screws haum PVC thiab ua haujlwm siab.
