Kev tsim kho tshuab ntxig rau PA66 thiab rooj kheej siv hluv tshaj | Tshuab ntxig kheej siv hluv tshaj

Kev tsim kho tshuab ntxig khoom yog qhov kev paub txog kev lag luam nyob rau hauv kev ntxig khoom, tshwj tsis yog rau cov khoom siv zoo li polyamide 66 (PA66) thiab cov duos uas muaj roj av. Nws tau sau nrog kev kho tshuab rau qhov chaw ntxig khoom, kev sov tshuab, kev caij khoom ntxig, kev tso siab, thiab kev tso khoom tawm kom pom zoo qhov khoom zoo, kev lag luam sai, thiab tshuab ntxig khoom nyob ntev. Rau cov khoom siv li PA66 uas muaj 25% sib thooj roj av (GF25), tus neeg tsim kho tshuab yuav tsum xav txog qhov tshuab ntxig khoom yuav tsum siv cov khoom nyob ntev li ntawv (xws li H13) lossis kev kho tshuab rau saum npaum kom tsis txhob puav. Kev kho tshuab rau qhov caij khoom ntxig—yog tias yog qhov caij lek, qhov caij nruab nray, lossis qhov caij khoom ntxig tsha tshaj—muaj kev pheej hmoo rau kev txiav txim siab qhov sib thooj roj av thiab qhov sib txuas, uas muaj kev pheej hmoo rau qhov zog tshaj tawm thiab kev tiv thaiv. Qhov chaw sov tshuab yuav tsum raug kho kom zoo los daws kev sov thiab tsis txhob muaj qhov kho tawb, vim tias PA66 GF25 muaj qhov sov dav hlau nyob rau 260°C thiab qhov tshuab ntxig khoom yuav tsum nyob rau 80–120°C. Qhov kev hloov chaw, feem ntau yog 0.2–0.5% hauv chaw thiab 0.5–0.8% sab nraud vim muaj sib thooj roj av, yuav tsum muaj kev kho tshuab kom raug. Qhov tso khoom tawm yuav tsum tiv thaiv khoom tsis txhob puav, siv cov tshuab tso khoom tawm lossis tshuab puv siab rau cov chaw meej meej. Qhov tso siab yog ib qhov tseem ceeb kom tso siab tawm thiab tsis txhob muaj kab ncauj, feem ntau siv cov tshuab tso siab lek lossis cov khoom siv porous. Cov tshuab simulation tshaj tawm pab ntxiv kom paub yuav pib, sov, thiab qhov tseem ceeb, kom reduce trial cycles. Nyob rau hauv cov kev lag luam xws li kev siv yas thiab kev nres tseg, kev kho tshuab ntxig khoom yuav tsum raug sib cuag nrog kev lag luam ntau thiab cov kev tswj fwm, xav kom muaj kev sib koom tes ntag ntag ntawm cov neeg paub txog khoom siv thiab cov neeg kho tshuab kom daws cov teeb meem xws li kev hloov chaw thiab kev sov. Thaum kawg, qhov kev kho tshuab ntxig khoom uas muaj kev sib koom ntawv ntawm cov khoom siv, kev lag luam, thiab kev siv khoom yog ib qhov tseem ceeb kom tau txais kev lag luam zoo thiab nyiaj tsawg rau cov khoom ntxig khoom.
