Rotational molding tuag, feem ntau xa mus rau cov pwm siv nyob rau hauv cov txheej txheem rotational molding, yog cov cuab yeej tseem ceeb hauv cov txheej txheem no.
Rotational molding, tseem hu ua rotomolding lossis rotational molding, yog ib txoj hauv kev ntawm hollow molding thermoplastics. Cov khoom siv yas yog ntxiv rau hauv pwm, uas yog tom qab ntawd kaw thiab ua kom sov thaum lub pwm tig ib ncig ntawm ob txoj hlua sib txuas. Qhov no ua rau cov yas raw khoom faib sib npaug thiab yaj hauv pwm, adhering rau saum npoo. Thaum kawg, nws txias thiab solidifies kom tau ib qho khoom hollow ntawm cov duab uas xav tau.
Kev tsim thiab tsim khoom ntawm rotational molding tuag muaj qhov cuam tshuam tseem ceeb rau qhov zoo thiab kev ua haujlwm ntawm cov khoom sib hloov pwm. Pwm cov ntaub ntawv feem ntau yog aluminium alloy, steel, lossis lwm yam siab -kub thiab corrosion- cov ntaub ntawv tiv taus kom ruaj khov thiab qhov ntev ntawm qhov kub thiab txias. Lub precision thiab nto tiav ntawm cov pwm ncaj qha cuam tshuam cov tsos thiab sab hauv zoo ntawm cov khoom rotationally molded; Yog li ntawd, kev ua thiab polishing ntawm cov pwm yog qhov tseem ceeb heev.
Nyob rau hauv cov txheej txheem molding rotational, pwm qhov kev sib hloov ceev thiab kev tswj qhov kub thiab txias yog ob yam tseem ceeb ntawm cov txheej txheem. Kev sib hloov ceev heev tuaj yeem ua rau tsis sib xws ntawm cov khoom siv yas, thaum qeeb qeeb qeeb qeeb yuav ua rau lub voj voog molding ntev thiab txo cov khoom tsim tawm. Kev tswj qhov kub thiab txias yog qhov tseem ceeb sib npaug. Kev kub siab heev tuaj yeem ua rau cov khoom siv yas decompose, thaum qhov kub thiab txias heev tuaj yeem tiv thaiv nws los ntawm melting tag nrho thiab adhering rau pwm sab hauv phab ntsa. Yog li ntawd, tus tsim ntawm rotational molding tuag yuav tsum tau ua tib zoo xav txog cov txheej txheem no los xyuas kom meej qhov kev vam meej ntawm rotational molding txheej txheem thiab stability ntawm cov khoom zoo.
