Peb- txheej co-extrusion tshuab tshuab tshuab muaj qhov zoo ntawm kev ua haujlwm siab, kev ua haujlwm yooj yim, tus nqi qis thiab siab membrane zoo. Nws tau siv dav hauv kev lag luam ntim khoom. Nrog rau kev txhim kho thev naus laus zis thiab kev xav tau ntawm kev lag luam nce ntxiv, kev ua tau zoo thiab thev naus laus zis ntawm peb - txheej co-extrusion tshuab tshuab tshuab tau txhim kho tas li, uas muab ntau txoj hauv kev rau kev tsim cov yeeb yaj kiab siab - zoo.
Peb- txheej co-extrusion tshuab tshuab yog siv dav hauv ntim khoom noj, ntim khoom kho mob, zaj duab xis ua liaj ua teb, cov ntaub ntawv hauv tsev thiab lwm yam. Cov yeeb yaj kiab tsim muaj lub zog tensile zoo heev, tiv thaiv tshav kub, tiv thaiv corrosion thiab pob tshab, tiv thaiv cov khoom lag luam zoo, ua kom lub neej ntev ntawm cov khoom thiab txhim kho kev sib tw ntawm cov khoom.
Dab tsi yog cov khoom siv raw rau peb - txheej co-extrusion tshuab tshuab?
Ua ntej, qhov zoo ntawm cov khoom siv raw yog siab dua. Qhov zoo ntawm cov ntaub ntawv raw ncaj qha cuam tshuam rau qhov zoo ntawm cov yeeb yaj kiab extruded, yog li nws yog ib qho tsim nyog yuav tsum xaiv cov khoom zoo hauv kev tsim khoom. Feem ntau, cov khoom siv raw yuav tsum muaj qhov zoo ductility, toughness thiab pob tshab los xyuas kom meej tensile lub zog thiab lub teeb transmittance films.
Qhov thib ob, qhov muaj pes tsawg leeg ntawm cov khoom siv raw yuav tsum ruaj khov. Peb- txheej co-extrusion tshuab tshuab feem ntau siv ntau- txheej cov khoom siv los ua cov yeeb yaj kiab. Yog li ntawd, nws yog ib qho tsim nyog los xyuas kom meej qhov sib npaug thiab ruaj khov ntawm txhua txheej ntawm cov khoom siv los xyuas kom meej cov qauv ntawm cov yeeb yaj kiab extrusion. Yog tias cov khoom siv raw khoom tsis ruaj khov, nws yog ib qho yooj yim ua rau cov yeeb yaj kiab extruded zoo li xoob, tawg thiab lwm yam teeb meem zoo.
Thib peb, cov khoom siv raw yuav tsum muaj kev ua haujlwm zoo. Cov khoom siv raw yuav tsum muaj kev ua haujlwm zoo nrog rau cov dej ntws index thiab yaj flowability. Qhov no ua kom cov ntaub ntawv zoo sib xws thaum lub sij hawm extrusion thiab tiv thaiv kev thaiv thiab xau, yog li ua tau zoo - cov yeeb yaj kiab zoo.
Raw khoom specifications yuav tsum sib phim. Peb- txheej co-extrusion tshuab tshuab feem ntau yuav tsum xaiv cov khoom siv raw khoom tshwj xeeb suav nrog qhov dav thiab tuab raws li cov khoom xav tau. Yog hais tias cov khoom siv raw specifications tsis sib xws, nws yog ib qho yooj yim rau extruded zaj duab xis qhov loj thiab thickness tsis ua raws li cov kev cai.
Thaum kho qhov kub thiab txias ntawm peb- txheej co-extrusion tshuab zaj duab xis tshuab, nws yog ib qho tsim nyog yuav tsum tau ua kom haum qhov kub ntawm sab sauv, nruab nrab thiab qis yas nruas nrog lub extrusion nozzle txhawm rau xyuas kom muaj kev sib koom ua ke ntawm qhov kub thiab txias, thiaj li tsim tau cov khoom zoo ntawm - cov khoom yas zoo. Nyob rau hauv lub chav kawm ntawm kev ua hauj lwm, kev soj ntsuam tas mus li thiab kev hloov kho yog xav tau los txhim kho kev tsim khoom thiab cov khoom zoo los ntawm kev kho qhov kub thiab txias raws li qhov xwm txheej tiag tiag.
Peb - txheej co-extrusion tshuab tshuab feem ntau muaj cov extruder, tuag lub taub hau, txheej cov menyuam, cov menyuam txias, cov menyuam yaus traction, kev tswj nruj thiab tshuab winding. Ib qho extruder heats thiab melts yas granules, ces nyem rau hauv ib zaj duab xis. Cov pwm ua ib zaj duab xis ncig cov khoom siv yas extruded. Cov menyuam txheej yog coated rau ntawm cov menyuam txias kom txias. Lub tshuab cua txias siv lub tshuab cua txias kom txias thiab ua kom cov yeeb yaj kiab. Lub traction roller rub cov yeeb yaj kiab kom tswj tau qhov nrawm thiab nrawm. Lub zog tswj qhov system tswj qhov nro ntawm cov menyuam traction thiab xyuas kom meej qhov sib xws thiab nruj ntawm zaj duab xis. Lub coiler yob cov zaj duab xis rau hauv lub nruas rau kev ua haujlwm tom ntej thiab siv.
