Mzere wandiweyani wopangira mapepala makamaka umakhala ndi magawo awa:

1. Dongosolo la Extrusion

Uwu ndiye "mtima" wa mzere wopanga, womwe umayang'anira kupanga pulasitiki zopangira pulasitiki kukhala yunifolomu yosungunuka.

· Extruder:

·Mtundu: Single screw extruder nthawi zambiri amagwiritsidwa ntchito, ndipo mapasa-screw extruder amagwiritsidwanso ntchito pazochitika zomwe zimapangidwa kwambiri komanso kusakaniza zofunika.

·Mafotokozedwe: Sankhani wononga diameter (monga Φ 90mm, Φ 120mm, Φ 150mm) ndi kutalika kwa chiŵerengero cha m'mimba mwake (L/D kawirikawiri osachepera 32:1, kawirikawiri 35:1) kutengera m'lifupi ndi makulidwe a bolodi. Pazida zodziwikiratu monga ABS, kapangidwe ka screw kayenera kukhala kocheperako (kuponderezana sikuyenera kukhala kokwera kwambiri) kuti zisawonongeke.

·Kupanga screw: Poyankha kusiyanasiyana kosungunuka kwa PP/PE/ABS, magawo oponderezedwa ndi ma metering a screw adzapangidwa mwapadera.

· Kusintha kwa Network:

·Ntchito: Sefa zonyansa ndi zinthu za carbide mu sungunuka kuti muwonetsetse kuti bolodi ili yabwino. Zosintha mosalekeza pazenera (monga mizati iwiri ndi lamba wa mauna) ndizokhazikika pakupanga mapepala okhuthala, popeza mtengo wosokoneza kupanga (m'malo mwa fyuluta) ndiwokwera kwambiri.

Pampu yamagetsi (yosasankha koma yovomerezeka kwambiri):

·Ntchito: yoyikidwa pakati pa extruder ndi nkhungu. Imatha kutulutsa zinthu zosungunuka mwamphamvu kwambiri, kuchotseratu kusinthasintha kwa makulidwe obwera chifukwa cha ma screw pulses. Ndi chida chofunikira kwambiri popangira -mapuleti okhuthala kwambiri, makamaka PP ndi ABS omwe amafunikira kuwala kwambiri, ndipo amatha kuwongolera kulondola kwambiri.

· Metal chitsulo nkhungu:

·Mtundu: Mawonekedwe a Hanger T-shaped die ndiye chisankho chodziwika bwino kwambiri.

·Zinthu: High grade alloy zitsulo, ndi mawerengedwe yeniyeni ndi processing wa njira otaya mkati kuonetsetsa yunifolomu otaya liwiro ndi kuthamanga kwa kusungunula kudutsa lonse m'lifupi mwa nkhungu milomo.

· Kusintha kwa milomo ya nkhungu: Wokhala ndi lamba kapena kukankha bawuti yosinthira bwino, kutsegula kwa milomo ya nkhungu kumatha kusinthidwa bwino pamanja kapena zokha kuti muwongolere kupatuka kwa gululo.

·Njira yotenthetsera: Nthawi zambiri amagwiritsa ntchito zotenthetsera zamkuwa kapena machubu, zowongolera bwino kutentha m'malo osiyanasiyana.

2. Kupanga ndi kuzizira dongosolo

Ichi ndiye chinsinsi chodziwira kusalala komanso mawonekedwe apamwamba a bolodi.

· Kalendala yamitundu itatu:

·Ntchito: Ichi ndiye chida chachikulu chopangira mzere wopangira mbale. Nsalu yosungunuka yotuluka mu nkhunguyo nthawi yomweyo imalowa mpata pakati pa zogudubuza zitatuzo, ndikuzikulungiza, kuziziziritsa, ndi kuumbidwa, ndipo zimapeza pamwamba ponyezimira.

·Kapangidwe kake: Nthawi zambiri amakhala ndi zodzigudubuza zitatu: chapamwamba, chapakati, ndi chapansi. Mkati mwa chodzigudubuza muli njira yawiri yozungulira yozungulira, yomwe imadzazidwa ndi mafuta osasinthasintha kuti athe kuwongolera kutentha.

·Makonzedwe odzigudubuza: Pali mitundu yoongoka, yopingasa, ndi ma℃45. The 45℃oblique angle ndiyo yofala kwambiri chifukwa imathandizira kufalikira kwachilengedwe kwa kusungunula ndikuchepetsa kupsinjika kwamkati.

· Kulipiritsa kutalika kwapakatikati: Chifukwa cha kupindika pang'ono kwa wodzigudubuza pansi pa kukanidwa, chodzigudubuza chapansi nthawi zambiri chimakhala ndi "kutalika kwapakatikati" (convexity) kuti athe kubwezera mapindikidwe ndikuwonetsetsa makulidwe a yunifolomu a pepala lopindidwa.

·Kusintha kwa gap: Mpata uliwonse ukhoza kusinthidwa pamagetsi kapena pamadzi kuti ugwirizane ndi makulidwe osiyanasiyana.

· Chozizira chimango chodulira:

·Ntchito: Kuziziritsanso bolodi yopangidwa kale kuti ikhale yotentha.

·Kapangidwe kake: Wopangidwa ndi magulu angapo (nthawi zambiri ambiri) odzigudubuza kapena oyendetsedwa mwachangu. Pali chodzigudubuza chothandizira pamwamba kuti chiteteze bolodi kuti lisagwedezeke.

·Njira yozizirira: kuzizirira mwachilengedwe kapena kuwonjezeredwa ndi kuziziritsa kwa mpweya.

3. Dongosolo ndi kudula

· Makina onyamula:

·Ntchito: Perekani kakokedwe kokhazikika kuti mutsogolere bolodi bwino kuchokera muzodzigudubuza zitatu ndi chimango chozizirira. Nthawi zambiri, ndi peyala imodzi kapena zingapo za mphira kapena silikoni zodzigudubuza, ndipo chogudubuza chapamwamba chimatha kukanikizidwa pansi.

· Chida chodulira/chosanjikira chokha:

· Tracking mtundu kudula macheka: Pa kudula, macheka tebulo synchronously amalondola kayendedwe ka bolodi, kubwerera ku malo ake oyambirira pambuyo kudula, ndipo amakwaniritsa atakhazikika kutalika kudula ndi kudula yosalala.

·Stacker crane: imalandira yokha matabwa odulidwa ndikuyika bwino. Kuyika pawokha ndikofunikira pama board olemera.

4. Dongosolo lothandizira

· Dongosolo lodyetserako chakudya: Makina oyamwa vacuum, omwe amanyamula zida kuchokera ku silo kupita ku hopper yotulutsa.

· Makina osakaniza: Ngati mtundu wa masterbatch kapena zowonjezera zina ziyenera kuwonjezeredwa, ziyenera kusakanikirana bwino ndi makina osakaniza poyamba.

· Hydraulic system: imapereka mphamvu kwa osintha mawonekedwe, kusintha nkhungu, ndi zina.

· Dongosolo lowongolera kutentha: limapereka kutentha ndi kuziziritsa koyenera kwa ma extruder, nkhungu, ndi zodzigudubuza zitatu (makina otentha amafuta, makina otenthetsera madzi).

· Dongosolo loyang'anira magetsi: dongosolo loyang'anira pakatikati lozikidwa pa PLC ndi zenera logwira, kuphatikiza ma drive onse, kuwongolera kutentha, makonda a parameter, komanso kuzindikira zolakwika.

PP (polypropylene):

· Zipangizo za crystalline zimakhala ndi kuzizira kwambiri.

·Kiyi yopangira: Kuwongolera kutentha kwa mipukutu itatu ndikofunikira kwambiri. The wodzigudubuza kutentha sayenera kukhala otsika kwambiri, apo ayi bolodi adzakhala Chimaona chifukwa mofulumira crystallization, ndi kupsyinjika mkati adzakhala mkulu, kupanga sachedwa warping mu siteji yotsatira. Nthawi zambiri, kutentha kopitilira muyeso (monga 80-100 ° C) kumafunika pakuziziritsa pang'onopang'ono.

·Kusamalira pamwamba: Pamwamba pa bolodi la PP si-zopanda polar. Ngati kusindikiza kapena kulumikiza kumafunika, makina ochizira corona amatha kuphatikizidwa kumbuyo kwa mzere wopanga.

PE (polyethylene):

· Makamaka HDPE, yokhala ndi kristalo wapamwamba komanso kukhuthala kwamphamvu kwambiri.

·Kiyi yopangira: Mofanana ndi PP, chidwi chiyenera kuperekedwa ku ndondomeko yozizira kuti mupewe kumenyana. The processing kutentha osiyanasiyana ndi lonse.

ABS (acrylonitrile butadiene styrene copolymer):

• Zida za amorphous zimakhudzidwa kwambiri ndi kutentha, sachedwa kuwonongeka komanso kukhala chikasu.

·Kiyi ya ndondomeko:

·Kutentha kwa kutentha: Onetsetsani kwambiri kutentha kwa gawo lililonse kuti musatenthedwe. Kapangidwe ka screw kuyenera kupewa kutentha kwambiri kwa shear.

Kuziziritsa: Monga pulasitiki ya amorphous, ABS imakhala ndi kutsika kozizira kocheperako kuposa PP/PE, koma kumafuna kusalala kwapamwamba kwambiri kuti ma roller atatu akwaniritse gloss yapamwamba.

Kuyanika: Zipangizo za ABS ziyenera kuumitsidwa pasadakhale! Nthawi zambiri, iyenera kuumitsidwa pa 80-85 digiri C kwa maola 3-4 kapena kuposerapo, apo ayi bolodi limatulutsa thovu kapena zizindikiro zamadzi.

Zida zopangira → Kuyanika (ABS ikufunika) → Extruder plasticization → Zosefera ndi chosinthira chophimba → Kukhazikika kwapampu ya zida (ngati mukufuna) → Kupanga nkhungu → Mipukutu itatu ya kalendala ndi kupanga → Kuziziritsa ndi kutumiza → Kutulutsa → Kudula kutalika kokhazikika → Kuyika → Kumaliza

Ngati mukufuna kuganizira zogula kapena kuwunika zida zotere, muyenera kulabadira:

1. Mphamvu zopangira ndi mafotokozedwe a bolodi: Tanthauzirani momveka bwino kutalika kwapamwamba / kucheperachepera, makulidwe osiyanasiyana, ndi mphamvu zopangira (kg / h) za matabwa ofunikira.

2. Mtundu ndi khalidwe la zigawo zikuluzikulu: Mulingo wopanga ndi kulondola kwa extruders, mapampu gear, nkhungu, ndi odzigudubuza atatu mwachindunji khalidwe la pepala zitsulo.

3. Mulingo wowongolera: Kukwera kwa kuchuluka kwa makina opangira makina, kumapangitsa kuti ntchitoyo ikhale yosavuta, komanso kukhazikika kwazinthu zomwe zimapangidwa (monga makina owerengera amadzimadzi).

4. Zomwe wopanga amapanga: Ikani patsogolo ogulitsa omwe ali ndi mbale zopambana za PP/PE/ABS.
