Ukushaya umshini wokubumba ukucubungula Ukulawulwa kokushisa kwebhodlela lePulasitiki
September 04, 2023
Iyacubungula amabhodlela epulasitiki anemishini yokubumba ebumba le yinto evamile yokucubungula ekusebenzeni kwepulasitiki. Ngakho-ke kufanele sikunake kuphi kulokhu kucubungula? Ngifuna ukukutshela izinga lokushisa, ukulawulwa kokushisa kubalulekile ukucubungula amabhodlela epulasitiki. Lapho usebenza umshini wokubumba onqenqemeni wokubumba ukucubungula, kuyadingeka ukunaka okuthile kokushisa okushisa ukuze kuqinisekiswe ukuthi kwenziwa ibhodlela lepulasitiki elifanele.
Akukho lokushisa lokugeleza: izinga lokushisa eliphakeme kakhulu lapho ukugeleza kungenzeki ngaphansi kwengcindezi ethile. Inani elithile lepulasitiki lingezwa emaphethelweni aphezulu e-sweomemeri e-capillary afa, afudumele emazingeni okushisa athile, okushisa njalo, ukuze kusetshenziswe i-10min entsha, uma impahla icindezelwe njalo, uma lokhu okufiphele kungaphumeleli ekufeni, Ngemuva kokukhululeka kwengcindezi kuzoba izinga lokushisa lezinto ezibonakalayo kuphakamisa ubunzima ngamadigri ayi-10, bese ufaka ingcindezi engapheli yosayizi ofanayo ngemuva kokubamba imizuzu eyi-10. Lokhu kuyaqhubeka kuze kube yilapho ukuncibilika kuphuma ku-die. Ukwehlisa izinga lokushisa ngamadigri ayi-10 ngamazinga okushisa angagezili ezintweni. I-Flow Temperature TF: izinga lokushisa lapho i-amorphoous polymer ishintsha kusuka esimweni esiningi kakhulu esimweni esibonakalayo. Kungumkhawulo ophansi wokushisa kwepulasitiki omangalisayo. Ukuvimbela Ukushisa kwe-TD: kubhekiswa ku-polymer esimweni sokugeleza kwe-viscous lapho izinga lokushisa likhula futhi, lizokwenza ukonakala kwensimbi yamangqamuzana kukhule, kanye namazinga okushisa lapho i-polymer check ecashile yokushisa lokushisa. I-Heansing Teansituretm: Ama-crystalline polymers, izinga lokushisa lapho ukhetho olungamampunge ezintathu - oku-odwe ngaphambilini isimo sesakhiwo se-macroolecular changerakhi esifundazweni esingafanele, esaziwa ngokuthi yindawo yokuncibilikisa. Kungumkhawulo ophansi wokushisa kokubumba kokushisa kwe-crystalline polymer. Ukushisa kwe-Glass Transition Temperatite TG: Kubhekiselwa ekushiseni kwe-Glassy esimweni esiningi kakhulu esimweni esibanzi noma kusukela ekugcineni kusimo se-Amorphous se-Amorphous Polymer). Kushisa okuphansi kakhulu kokunyakaza kwamahhala kwe-Amorphous Polymer Macromolekser Segment, futhi futhi kungumkhawulo ophezulu wokushisa komkhiqizo.
