Rotomolding yog txoj kev nyiam ntawm kev tsim ntau yam khoom yas hollow siv nyob rau hauv peb lub neej niaj hnub, thiab nws yog ib qho ntawm cov kev lag luam loj tshaj plaws hauv kev lag luam plastics hauv kaum xyoo dhau los.
Tsis zoo li lwm txoj kev ua, cov cua sov, melting, molding, thiab txias theem ntawm rotational molding tshwm sim tom qab lub polymer muab tso rau hauv pwm, uas txhais tau hais tias tsis muaj lwm lub siab yuav tsum tau thaum lub sij hawm molding txheej txheem.
Cov pwm nws tus kheej feem ntau yog ua los ntawm cam khwb cia txhuas, CNC machined txhuas, los yog hlau.Piv nrog cov pwm siv hauv lwm txoj hauv kev (xws li txhaj tshuaj lossis tshuab moulding), pwm kuj pheej yig.
Rotational molding txheej txheem yog qhov yooj yim, tab sis nws yog ntau yam.Ua ntej, cov kab noj hniav yog ntim nrog cov hmoov polymer (sib tham hauv nqe lus hauv qab no).
Tom qab ntawd lub qhov cub yog rhuab mus rau ib ncig ntawm 300 ° C (572 ° F) thaum lub pwm tig ntawm ob axes kom tusyees faib cov polymer.Lub hauv paus ntsiab lus yog tias cov hmoov nplej (feem ntau yog li 150-500 microns) yuav fuse ua ke los tsim cov khoom tiav tas mus li.Qhov kawg tshwm sim ntawm cov khoom yog nyob ntawm qhov loj ntawm cov hmoov nplej.
Thaum kawg, cov pwm yog txias thiab cov khoom raug muab tshem tawm kom tiav.Lub sijhawm voj voog ntawm cov txheej txheem rotomolding yooj yim tuaj yeem sib txawv ntawm 20 feeb mus rau 1 teev, nyob ntawm qhov loj thiab qhov nyuaj ntawm cov khoom.
Nyob ntawm qhov xav tau cov khoom kawg, ntau hom yas polymers tuaj yeem siv hauv rotomolding.
Ib qho yas siv feem ntau yog polyethylene (PE) vim tias nws tuaj yeem tiv taus qhov kub thiab txias tau ntev thiab pheej yig heev.Tsis tas li ntawd, tsawg-density PE yog hloov tau yooj yim thiab resistant rau fracturing.
Mouldmakers kuj feem ntau siv ethylene-butyl acrylate vim tias cov khoom no muaj kev sib tsoo thiab lub zog ntawm qhov kub thiab txias.Zoo li feem ntau cov thermoplastics, nws muaj qhov zoo ntxiv ntawm kev ua kom yooj yim dua
Txawm hais tias polypropylene yog cov yas siv dav, nws tsis yog thawj qhov kev xaiv ntawm ntau cov moldmakers.Yog vim li cas yog tias cov khoom no ua nkig nyob ze ntawm chav tsev kub, yog li cov tuam ntxhab muaj sijhawm me ntsis los tsim cov khoom.
Ntau yam khoom txhua hnub yog tsim los ntawm kev sib hloov molding, raws li cov khoom lag luam customized.Qee qhov piv txwv tau muab hauv qab no:
Rotomolding yog ib txoj kev molding zoo heev, uas tso cai rau cov tuam txhab tsim khoom tsis yog tsuas yog tsim cov khoom siv ruaj khov nrog cov qauv tsim tsawg, tab sis kuj tsim cov khoom zoo ib puag ncig ntawm tus nqi qis.Tsis tas li ntawd, cov khoom lag luam loj tuaj yeem tsim tau yooj yim hauv kev lag luam, nrog cov khoom siv tsawg heev.
Rotomolding tuaj yeem teeb tsa sai, uas tuaj yeem ua tau raws li qhov xav tau thiab tsim tawm hauv cov khoom me me.Nws pab txo qis cov khoom lag luam thiab cov khoom lag luam muaj peev xwm rov ua dua, ua rau nws feem ntau pheej yig piv rau kev tsim khoom, fiberglass, txhaj tshuaj, nqus tsev, los yog tshuab molding txoj kev.
Lub versatility ntawm rotational molding kuj yog ib qho ntawm nws qhov zoo.Nws tso cai rau cov khoom tsim tsis muaj cov kab nrib pleb, nrog ntau txheej txheej thiab ntau yam qauv, xim thiab nto tiav.Rotomolding tuaj yeem tsis tsuas yog haum rau cov khoom siv, tab sis kuj muaj lub logo, grooves, nozzles, tus thawj coj thiab ntau lub luag haujlwm kom ua tau raws li qhov xav tau ntawm kev tsim thiab engineering.Tsis tas li ntawd, siv txoj kev no tuaj yeem tsim ntau hom khoom ua ke ntawm ib lub tshuab.
Gary kawm tiav los ntawm University of Manchester nrog thawj chav kawm honors degree hauv geochemistry thiab kawm tiav qib siab hauv geosciences.Tom qab ua haujlwm hauv Australian mining kev lag luam, Gary txiav txim siab los dai nws cov khau geology thiab pib sau ntawv hloov.Thaum nws tsis tsim cov ntsiab lus thiab cov ntaub ntawv, feem ntau koj tuaj yeem pom Gary ua si nws tus hlub guitar, lossis saib Aston Villa Football Club yeej thiab poob.
