Roto {- moulded nkoj feem yog cov khoom siv yas ntim hauv cov khoom tseem ceeb xws li cov khoom tseem ceeb xws li cov khoom siv tseem ceeb xws li cov khoom siv hauv pliaj, tso tsheb hlau luam, daug ntsej muag, thiab buoys. Roto {{2} moulded seem yog tsim tau siv roto {}} cov tswv yim moulding, thiab muaj zog corrosion tsis kam. Cov kev ua tau zoo ntawm Roto - moulded seem nyob ntawm cov ntaub ntawv tseem ceeb rau lub nkoj loj thiab lawv cov khoom tseem ceeb rau cov khoom siv roj av polyethylene (HDPE)
Siab -} ceev polyethylene (HDPE) yog ib qho ntawm cov khoom siv roto} Moulding rau ntau tshaj 60% ntawm tag nrho. Cov khoom siv no muaj cov tshuaj tiv thaiv zoo heev, tiv thaiv corrosion los ntawm kev tawm hauv dej hiav txwv, roj roj, ua kom haum rau cov thawv tso tsheb hlau luam, cov kav dej piping, thiab ntim khoom siv. Tsis tas li ntawd, HDPE yog qhov cuam tshuam heev - tiv taus thiab tsis tshua muaj kev ntseeg tau, ua kom muaj kev ntseeg tau ntawm cov nkoj hnyav. Nws qis ntom ntom yuav pab kom txo qhov hnyav tag nrho ntawm cov nkoj, yog li kev txhim kho roj efficiency.
Polypropylene (pp)
Polypropylene (PP) yog lwm cov khoom siv dav siv rau roto - moulded nkoj qhov chaw, feem ntau yog qhov uas siab dua kub kuj yuav tsum muaj. PP muaj lub siab melting taw tes (kwv yees li 160 degree), ua rau nws cov khoom siv marine raug rau cov tsheb thauj khoom kub, xws li lub tshuab ntim khoom siv hluav taws xob lossis cua sov. Compared to HDPE, PP offers greater rigidity and improved flexural fatigue resistance, making it suitable for withstanding long-term mechanical stress. Txawm li cas los xij, pp qhov qes qis - kub kuj yog me ntsis qis dua rau HDPE, thiab nws yuav dhau los ua ib puag ncig txias heev. Yog li ntawd, nws siv hauv cov dej txias yuav tsum tau tshuaj xyuas.
Hla - Txuas Polyethylene (XLPE)
Hla -} Txuas Polyethylene (XLPE) yog cov khoom hloov kho uas nws cov molecular charts yog hla los ntawm kev siv tshuaj lom neeg lossis kev siv lub cev. Nws ua kom pom kub ua kom zoo dua qub, kev ntxhov siab ib puag ncig kev tawg (esc) tsis kam, thiab hnav tsis kam piv rau tus qauv HDPE. XLPE feem ntau siv nyob rau hauv high- Lub zog retationally ci loj, thiab cov khoom siv nthuav tawm rau UV thav duab thiab dej hiav txwv corrosion. Nws cov ntoo khaub lig {{{}} Txuas cov qauv sib xws, txo qhov kev pheej hmoo ntawm deformenseal tom qab ntev siv sijhawm ntawm lub neej ntawm marine.
Nylon (PA) thiab lwm yam kev tsim khoom loj
Txawm hais tias Nylon (PA) yog tsis tshua siv nyob rau hauv rotomolding, xws li tus kheej lubricating cov khoom lag luam ua kom nws lub tsev zoo, thiab cov txheej txheem kev tsim qauv, thiab cov qauv txheej txheem raug kaw. Tsis tas li ntawd, qee qhov siab- kev ua yeeb yam rau cov tshuaj lom neeg uas muaj kev sib cav sib ceg (PPS Txawm li cas los xij, cov ntaub ntawv no nyuaj thiab kim rau cov txheej txheem, thiab feem ntau tsuas yog siv nyob rau hauv high-}} kev lag luam tshwj xeeb.
Cov ntaub ntawv tseem ceeb siv rau cov tub rog rotomolded suav nrog high {0} {} {}}}}}}}}}}}}}}} Txhua cov ntaub ntawv muaj cov kev ua tau zoo tshwj xeeb rau cov kev siv marine sib txawv. HDPE yog qhov kev xaiv tseem ceeb yog tag nrho cov kev ua tau zoo tshaj plaws, thaum PP, XLPE, thiab tshwj xeeb plastects ua si lub luag haujlwm tseem ceeb hauv cov ntawv thov tshwj xeeb. Nyob rau hauv lub neej yav tom ntej, nrog kev nce qib hauv rompolding thev naus laus zis thiab kev txhim kho cov khoom tshiab, txuas ntxiv txhim kho, thiab ib puag ncig kev ua haujlwm ntawm marine.
