Introduction to Rotational Moulding Process (Pib 2)

二,Kev sib hloov moldingKev sib hloov moulding ntau lawm yog tsim los ntawm pab pawg thawj coj nyob rau hnub ntawd raws li kev cob qhia kev tsim khoom.
(一) Tshawb xyuas qhov system roj
Cov roj siv hluav taws xob yog qhov tseem ceeb ntawm kev sib hloov molding kev ruaj ntseg ntau lawm, uas yuav tsum tau kuaj xyuas, kho, tswj, qhib thiab kaw los ntawm cov neeg ua haujlwm tshwj xeeb. Ib tus neeg ua haujlwm tsis cuam tshuam yuav tsis ua haujlwm saum toj no. Tus neeg tsav tsheb roj yuav tsum xyuas cov xwm txheej ntawm cov roj hluav taws xob ua ntej kev sib hloov molding ntau lawm txhua hnub, kos npe rau ntawm daim ntawv tshuaj ntsuam xyuas tom qab lees paub tias lub kaw lus zoo li qub, pib lub tshuab roj raws li cov cai ua haujlwm tom qab kos npe ntawm pawg thawj coj, kaw. gas system tom qab ua tiav kev ua haujlwm, kos npe rau ntawm daim ntawv tshuaj ntsuam xyuas roj tom qab kev tshuaj ntsuam xyuas yog qhov qub, thiab tawm ntawm qhov chaw tom qab kos npe ntawm pawg thawj coj.
1. Tshawb xyuas lub yob qub
Ua ntej rotational molding ntau lawm, xyuas seb txhua lub cuab yeej ntawm lubkev sib hloov moldingtshuab yog ib txwm.
2. Nruab lubkhoom pwm
Lub ntsiab lus tseem ceeb ntawm cov khoom pwm kev teeb tsa yog seb qhov kev teeb tsa ntawm ntau qhov pwm ntawm lub rotating caj npab yog sib npaug, seb lub installation txoj hauj lwm thiab qhov hnyav yuav tsum tau kho. Tsis tas li ntawd, kev txhim kho pwm yuav tsum tau them sai sai rau kev siv cov tshuaj ntxuav tes los ntxuav thiab ziab cov kab noj hniav ua ntej kev teeb tsa cov pwm tshiab. Cov kauj ruam tshwj xeeb yog raws li hauv qab no:
(1) Lub combustion chamber ntim yuav tsum tau txiav txim siab tag nrho ua ntej kev teeb tsa pwm, tshwj xeeb tshaj yog seb lub kab pheeb suab tag nrho ntawm ntau cov pwm ntau tshaj li qhov ntim ntawm cov combustion chamber thaum ntau cov pwm tau dai ntawm ib sab caj npab.
(2) Cov pwm yuav tsum tau ua kom ruaj khov thiab tag nrho cov fastening screws yuav tsum tau nruj.
(3) Tom qab cov pwm raug teeb tsa, nws yuav tsum txias rau 5 ~ 10 lub voj voog yam tsis muaj kev thauj khoom. Tshawb xyuas kev ua haujlwm, qhov hnyav thiab ruaj khov ntawm cov khoom siv.
2. Cov tshuaj tsuag tso tawm
Cov txheej txheem ntawm pwm tso tawm tus neeg sawv cev sib txawv vim cov khoom sib txawv. W59 yog tsim rau thermal txau. Ntawd yog, qhov ntxuav thiab ntsia pwm tig qhov chaw yog txias rau lub combustion chamber rau cua sov. Thaum qhov kub siab tshaj 100 ℃ sib npaug, nws yog spun tawm thiab txias rau 100 ℃. Qhib lubpwmkom tusyees txau tus neeg sawv cev tso rau ntawm sab hauv ntawm cov pwm. Kev txau ntawm tus neeg sawv cev tso tawm yog nqa tawm ua ntej thawj zaug thiab tsim cov khoom. Thaum lub sijhawm ua cov khoom lag luam, nws yuav tsum tau muab tshuaj tsuag kom zoo raws li qhov teeb meem demoulding ntawm ib yam khoom.
