Roto - moulded feem yog dav siv nyob rau hauv kev tsim khoom lag luam vim yog lawv cov kev tsim qauv, xws li cov chaw ntim khoom, xws li cov fender, thiab cov khoom dai. Txawm li cas los xij, kev tu tsis raug cai nyob rau lub sijhawm tuaj yeem ua rau muaj kev tsis txaus ntseeg thiab muaj kev phom sij muaj kev nyab xeeb. Mastering Science Kev Tswj Xyuas yog qhov tseem ceeb heev los txuas lub neej ntawm roto - moulded seem.
Niaj hnub ntxuav yog ib qib kev txij nkawm yooj yim. Nws raug nquahu kom so lub ntsej muag nrog ib daim ntaub mos muag thiab cov ntaub so tes, zam kev puas tsuaj rau cov qauv saum npoo av ntawm lub roto {2} moulded ntu. Cov tawv ncauj tsuas tuaj yeem kho tau los ntawm luv luv kom dej sov, tab sis zam kev muaj zog acids thiab alkalines, raws li cov tshuaj no tuaj yeem nrawm cov khoom siv tau ua rau muaj cov khoom siv. Rau qhov chaw raug rau cov ntsiab lus rau ncua sij hawm, xws li lub ru tsev sib txuas lossis cov pob qij txha tuaj yeem tiv thaiv cov tsiaj kom tau los ntawm kev co.
Kev kho ib puag ncig kev hloov kho kuj tseem yog qhov tseem ceeb. Thaum siv qhov chaw rotomolded hauv thaj chaw kub, tsis txhob muaj lub hnub ci ci ncaj qha, raws li ultraviolet rays tej zaum yuav ua rau muaj nkig. Nyob rau hauv ib puag ncig txias, zam dheev siv cov dej kub ntawm qhov chaw khov, raws li thermal expansion thiab mortaction tuaj yeem yooj yim ua rau cov kab nrib pleb. Khaws rau hauv qhov chaw qhuav thiab muaj cua sov, thiab cov ntaub ntawv cushion thaum sib tsoo los tiv thaiv kev deformation.
Kev tshuaj xyuas ib txwm yog qhov tseem ceeb. Cov neeg siv yuav tsum tshuaj xyuas cov npoo thiab cov nqaws ntawm qhov chaw rotomracted peb lub hlis twg rau kev tawg lossis kev sib tawg. Kev tshawb nrhiav ntxov tuaj yeem kho nrog cov nplaum tshwj xeeb. Yog tias muaj kev puas tsuaj hnyav tshwm sim, nws raug nquahu kom hloov nws sai kom tsis txhob ua rau muaj kev nyab xeeb ntawm tag nrho cov tsheb.
Cov kev saib xyuas kom tsim nyog tsis tsuas txhim kho lub durability ntawm cov seem tab sis kuj txo nqi hloov. Muab cov lus qhia meej txog cov lus qhia thaum sib txuas lus nrog cov neeg txawv teb chaws tuaj yeem pab cov khoom lag luam kev sib tw ntawm kev ua lag luam thoob ntiaj teb.
