Hollow tshuab moulding txoj kev taw qhia:
Vim qhov sib txawv ntawm cov khoom siv raw, kev ua haujlwm, cov khoom siv thiab cov nqi, cov tshuab molding sib txawv muaj qhov zoo sib txawv hauv kev ua cov khoom sib txawv.
Tshuab moulding ntawm cov khoom hollow muaj peb txoj hauv kev tseem ceeb:
1, extrusion tshuab moulding: tsuas yog siv rau kev ua haujlwm tsis muaj kev txhawb nqa;
2, txhaj tshuaj molding: feem ntau yog siv rau kev ua cov pob zeb uas txhawb nqa los ntawm cov tub ntxhais hlau;
3, stretch tshuab moulding: nrog rau extrusion ib stretch tshuab molding, txhaj ib stretch tshuab molding ob txoj kev, yuav ua tau biaxial oriented khoom, zoo heev txo nqi ntau lawm thiab txhim kho cov khoom ua tau zoo.
Tsis tas li ntawd, muaj ntau txheej tshuab moulding, nias tshuab moulding, dip txheej tshuab moulding, foaming tshuab moulding, peb-dimensional tshuab moulding, thiab lwm yam. Txawm li cas los xij, 75% ntawm cov tshuab tshuab moulding yog extrusion tshuab moulding, 24% yog txhaj tshuab. molding thiab 1% yog lwm yam tshuab molding.Ntawm tag nrho cov tshuab molding khoom, 75% belongs rau bidirectional stretch khoom.Qhov zoo ntawm extrusion tshuab moulding yog kev ua haujlwm siab, cov cuab yeej siv qis, ntau yam pwm thiab cov tshuab xaiv, qhov tsis zoo yog cov khoom siv siab, cov khoom siv pov tseg, kev siv tsis zoo, cov khoom thickness tswj, dispersity ntawm raw khoom yog txwv, tom qab molding yuav tsum. yuav kho ntug kev ua haujlwm.Qhov zoo ntawm kev txhaj tshuaj molding yog tias tsis muaj pov tseg hauv cov txheej txheem ntawm kev ua, phab ntsa tuab ntawm cov khoom thiab cov khoom tawg tuaj yeem tswj tau zoo, qhov tseeb ntawm cov khoom siv caj dab nyias yog siab, qhov chaw ntawm cov khoom yog du, thiab me me batch ntau lawm yuav nqa tawm economic.Qhov tsis zoo yog tus nqi siab ntawm cov khoom siv molding, thiab rau qee qhov tsuas yog tsim rau cov khoom me me tshuab molding.
Cov txheej txheem ntawm hollow tshuab moulding xav kom cov cua compressed ntawm nruab nrab billet ntawm tshuab pwm yuav tsum huv.Txhaj tshuab moulding cua siab yog 0.55 ~ 1MPa;Extrusion tshuab moulding siab yog 0.2L ~ 0.62mpa, thaum tensile tshuab moulding siab feem ntau yuav tsum siab li 4MPa.Nyob rau hauv cov yas solidification, tsis tshua muaj siab ua rau sab hauv kev ntxhov siab ntawm cov khoom qis, kev nyuaj siab dispersion yog ntau yam, thiab kev ntxhov siab tsawg tuaj yeem txhim kho tensile, cuam tshuam, khoov thiab lwm yam khoom ntawm cov khoom.
