1. Npuas zaj duab xis tsis ruaj khov
1) Qhov kub extrusion tsawg dhau thiab qhov paug tawm me me;
Tshuaj: kho extrusion kub;
2) Nws tau cuam tshuam thiab cuam tshuam los ntawm cov huab cua sab nraud muaj zog.
Kev daws: tiv thaiv thiab txo qhov cuam tshuam ntawm sab nraud airflow.
3) Cov cua ntim ntawm lub nplhaib cua txias tsis ruaj khov, thiab cov cua txias ntawm npuas zaj duab xis tsis zoo li qub;
Kev daws: Txheeb xyuas lub nplhaib cua txias kom ntseeg tau tias huab cua nyob ib puag ncig;
4) Extrusion kub yog siab dhau lawm, lub fluidity ntawm fused resin yog loj heev, viscosity tsawg dhau, yooj yim los tsim fluctuations;
Kev daws: Kho qhov kub thiab txias extrusion;
2. Lub tshav kub sealing ntawm zaj duab xis tsis zoo
1) Yog tias cov dej lwg qis dhau lawm, cov molecules polymer yuav tau taw qhia, kom qhov kev ua tau zoo ntawm cov yeeb yaj kiab yog ze rau ntawm cov yeeb yaj kiab taw qhia, ua rau txo qis ntawm cov cua sov sealing kev ua tau zoo;
Kev daws: Kho qhov loj ntawm cov huab cua ntim hauv lub nplhaib, ua rau cov dej lwg taw tes siab dua, kom deb li deb tau raws li qhov ua tau raws li qhov xav tau ntawm cov yas tshuab thiab traction, txhawm rau txo cov molecular stretching orientation los ntawm tshuab thiab traction;
Yog tias qhov sib piv ntawm qhov sib piv thiab qhov sib piv tsis tsim nyog (loj dhau), zaj duab xis yuav muaj tensile orientation, uas yuav cuam tshuam rau thermal sealing kev ua tau zoo ntawm zaj duab xis.
Kev daws: tshuab piv thiab traction ratio yuav tsum tsim nyog me me, yog hais tias tshuab piv yog loj heev, thiab traction ceev yog heev ceev, kab rov tav thiab longitudinal tensile ntawm zaj duab xis yog ntau dhau, ces nws yuav ua rau cov kev ua tau zoo ntawm cov zaj duab xis nyhav rau bidirectional. tensile, zaj duab xis tshav kub sealing yuav ua phem.
3. Qhov saum npoo ntawm zaj duab xis yog ntxhib thiab tsis sib xws
1) Qhov kub extrusion tsawg dhau, cov resin plasticization tsis zoo;
Kev daws: Kho qhov extrusion kub qhov chaw, thiab tsim nyog nce lub extrusion kub, kom paub meej tias cov resin plasticized zoo
2) Lub extrusion ceev ceev heev.
Kev daws: Txo extrusion ceev kom tsim nyog
