● Xyuas qhov kub ntawm lub plawv pwm. Yog tias nws siab dua qhov kub ntawm qhov seem pwm, txo qhov kub ntawm lub plawv;
● Ntxuav cov khoom sib xyaw ntawm pwm;

2. Cov kab nrib pleb tshwm sim rau ntawm qhov chaw sab nraud ntawm cov yeeb nkab yas
● Kho qhov siab ntawm qhov dej tawm ntawm lub tes tsho sizing, thiab qhov dej tawm yuav tsum tau sib npaug;
● Kho lub kaum sab xis ntawm lub nozzle hauv lub thawv nqus tsev kom cov yeeb nkab txias sib npaug;
● Xyuas lub pwm, qhov loj ntawm lub tes tsho, lub tshuab txiav, thiab lwm yam khoom siv kom paub seb puas muaj cov khib nyiab, cov kab nrib pleb, thiab lwm yam.

3. Cov kab nrib pleb tshwm sim rau sab hauv
● Xyuas seb dej puas nkag mus rau hauv lub raj sab hauv. Yog tias dej nkag mus, nias lub raj ntawm lub pwm tom qab tawm mus kom kaw lub qhov hauv;
● Txo qhov kub sab hauv ntawm pwm;
● Ntxuav thiab txhuam cov pwm;

4. Ib lub nplhaib jitter tshwm sim hauv cov yeeb nkab
● Kho qhov dej tawm ntawm lub tes tsho ntsuas kom nws sib npaug;
● Kho qhov degree nqus ntawm lub chamber thib ob kom qhov degree nqus ntawm lub chamber tom qab siab dua qhov degree nqus ntawm chav pem hauv ntej me ntsis;
● Xyuas seb lub foob nqus tsev puas nruj dhau;
● Xyuas seb lub tsheb laij teb puas co;
● Xyuas seb lub tshuab tseem ceeb puas tso tawm sib npaug;

5. Tsis muaj lub tshuab nqus tsev
● Xyuas seb qhov dej nkag ntawm lub twj nqus tsev puas raug thaiv. Yog tias nws raug thaiv, qhib nws;
● Xyuas seb lub twj tso kua mis puas feem ntau ua haujlwm;
● Xyuas seb lub raj xa dej puas xau;
● Xyuas seb lub qhov me me hauv nruab nrab ntawm lub hau ntswj pwm puas raug thaiv. Yog tias nws raug thaiv, siv cov hlau nyias nyias los ntxuav nws;

6. Lub sab nraud ntawm lub yeeb nkab tsis muaj kev kam rau siab
● Qhov loj ntawm lub voj voog sab nraud tuaj yeem hloov pauv los ntawm kev kho qhov degree nqus tsev;
● Qhov loj ntawm lub nplhaib sab nraud tuaj yeem hloov pauv los ntawm kev hloov qhov ceev ntawm traction;
● Kho qhov loj ntawm lub qhov sab hauv ntawm lub tes tsho ntsuas qhov loj;

7. Lub voj voog ntawm cov yeeb nkab tsis yog qhov kam rau siab
● Kho lub kaum sab xis ntawm lub nozzle hauv lub tshuab nqus tsev thiab lub thawv tsuag kom txias cov yeeb nkab sib npaug;
● Tshawb xyuas lub tshuab nqus tsev, qib dej hauv lub thawv tsuag, thiab lub zog ntawm lub ntsuas dej kom ua rau lub ntim tsuag loj thiab muaj zog;
● Xyuas qhov kub ntawm lub tshuab nqus tsev thiab lub thawv tsuag. Yog tias nws >35℃, lub tshuab dej txias lossis lub thawv tsuag txias yuav tsum ntxiv;
● Tshawb xyuas cov dej ntws thiab ntxuav lub lim;
● Kho cov txheej txheem;
● Tshawb xyuas thiab kho qhov puag ncig ntawm lub qhov sab hauv ntawm lub tes tsho sizing;
● Kho cov yeeb nkab qhia thiab cov cuab yeej clamping kom hloov kho qhov ovality ntawm cov yeeb nkab;

8. Cov yeeb nkab phab ntsa tsis sib npaug
● Kho qhov tuab ntawm phab ntsa ntawm pwm;
● Kho lub kaum sab xis ntawm lub nozzle hauv lub tshuab nqus tsev thiab lub thawv tsuag kom cov yeeb nkab txias sib npaug; kho qhov tso zis dej ntawm lub tes tsho ntsuas kom nws sib npaug;
● Tshem cov pwm, xyuas seb cov ntsia hlau hauv pwm puas xoob, thiab rov ua kom nruj dua;

9. Qhov kub ntawm cov yas yas siab dhau lawm
● Kho cov txheej txheem;
● Kho qhov kub ntawm lub pwm thiab ua kom lub pwm txias thiab cua nkag;
● Qhov kub ntawm lub hau ntswj siab dhau lawm, hloov lub hau ntswj;

10. Qhov ntev txiav tsis raug
● Xyuas seb lub log ntev puas nias nruj nreem;
● Xyuas seb lub log ntev puas tig, thiab zawm cov ntsia hlau ntawm lub thav duab log ntev;

Txhua lub qhov rooj uas sawv ntawm nws tus kheej (PE terminal) yuav tsum tau muab grounded cais rau ib qho chaw grounding tag nrho kom ntseeg tau grounding. Qhov chaw grounding yuav tsum muaj ib qho grounding stake uas ua tau raws li qhov yuav tsum tau electrical grounding. Nws tsis raug tso cai txuas cov qhov rooj uas sawv ntawm nws tus kheej (PE terminals) ua ke thiab ground. Txwv tsis pub, lawv yuav ua rau muaj Interference pulse, ua rau qhov ntev txiav tsis raug;

11. Teeb meem ntawm daim ntawv lo co-extrusion
Kev sib kis ntawm cov ntawv cim qhia txog kev sib koom ua ke: Feem ntau, nws ua rau kev xaiv tsis raug ntawm cov neeg siv cov ntaub ntawv sib koom ua ke. Cov ntaub ntawv tshwj xeeb, xws li PE, yuav tsum tau siv. Yog tias tsim nyog, qhov kub ntawm qhov seem extrusion tuaj yeem txo qis;
Lub tshuab co-extruder tsis tuaj yeem zawm tawm: nres lub tshuab extruder tseem ceeb, tig rau lub tshuab co-extrusion ua ntej, thiab tig rau lub cuab yeej co-extrusion li 10 feeb ua ntej tig rau tus tswv tsev;
Daim kab cim co-extrusion nyias dhau los yog dav dhau: Feem ntau, nws ua rau muaj qhov tsis sib xws ntawm qhov ntim extrusion ntawm lub tshuab co-extrusion thiab qhov ceev traction ntawm cov yeeb nkab thiab yuav tsum tau kho, qhov zaus ntawm lub converter zaus ntawm lub cav co-extrusion lossis hloov qhov ceev traction kom phim ob tus nqi;
Qhov thib ob yog qhov laj thawj vim li cas lub tsho dej txias ntawm qhov seem unloading ntawm lub co-extruder tsis dhau los ntawm cov dej txias;
Hauv cov txheej txheem tsim khoom tiag tiag ntawm cov yeeb nkab tsim kab, yuav muaj lwm yam xwm txheej tsis zoo, uas yuav tsum tau daws raws li qhov xwm txheej tseeb.
