Rotational Moulding Materials: LLDPE Vs. HDPE

1. Kev taw qhia txog cov khoom siv molding rotational

Kev sib hloov moldingcov ntaub ntawv xav tau los txhawb kev tsim cov khoom muaj zog, hollow yas. Roto molding, raws li cov txheej txheem tsim cov yas no kuj tseem paub, yog nrov ntawm cov neeg tsim khoom vim nws cov nqi qis thiab cov cuab yeej hloov kho sai. Rotational molding kuj txhawb kev tsim cov duab uas tsis tuaj yeem tsim nrog lwm txoj kev yas molding. Tsis tas li ntawd, roto molding yog hloov tau txaus rau ob qho tib si me me, intricate khoom thiab loj, complex sib dhos.

 

Ib feem tsim thiab cov nqi cuab yeej tseem ceeb, tau kawg, tab sis yog li roto molding khoom xaiv. Nrog rau polypropylene (PP) thiab zoo li qub-dissipative polyethylene (PE), ib feem tsim thiab cov kws tsim khoom lag luam tuaj yeem hais qhia tawm linear low-density polyethylene (LLDPE) thiab high-density polyethylene (HDPE). Kev nkag siab qhov sib txawv ntawm LLDPE thiab HDPE yog qhov tseem ceeb tshwj xeeb vim tias cov ntaub ntawv no zoo ib yam ntawm cov tshuaj muaj pes tsawg leeg tab sis tsis zoo ib yam ntawm cov khoom ua haujlwm.

 

2. LLDPE Rotational Moulding

LLDPEmuaj qhov nruab nrab nruj thiab lub zog tensile siab, qhov siab tshaj plaws ntawm cov khoom siv tuaj yeem tiv taus thaum rub lossis ncab ua ntej tawg. Txawm hais tias LLDPE yog qhov ruaj khov, cov khoom siv sib hloov molding no suav tias yog kev zam txim. Cov ntawv thov rau LLDPE rotational molding muaj xws li cov tso tsheb hlau luam, cov thoob, cov thawv, thawv, cov khoom ua si, thiab cov khoom ua si sab nraum zoov thiab cov khoom siv.

Virgin LLDPE cov ntaub ntawv paub txog lawv cov tshuaj tiv thaiv thiab kev ntxhov siab ib puag ncig. Rau kev siv sab nraum zoov, cov khoom siv molding no tuaj yeem txhim kho nrog ultraviolet (UV) lub teeb stabilizers thiab nrog cov tshuaj tiv thaiv kab mob lossis cov tshuaj tiv thaiv kab mob. Txhawm rau tsim cov khoom rotomolded hauv cov xim tshwj xeeb, LLDPE tuaj yeem sib xyaw nrog cov xim.

 

3. HDPE Rotational Moulding

HDPE kuj muaj lub zog tensile siab tab sis muaj zog dua LLDPE. Qhov no ua rau HDPE yog qhov kev xaiv zoo dua rau qee lub tank yas, thiab rau cov khoom xws li cov nkoj nkoj, cov tsheb thauj khoom, thiab cov nkoj hauv av. HDPE rotational molding tseem tuaj yeem txhawb nqa cov khoom lag luam, xws li cov khoom siv hauv kev lag luam ua zaub mov, uas yuav tsum ua raws li cov lus qhia los ntawm Food and Drug Administration (FDA) lossis US Department of Agriculture (USDA). Zoo li LLDPE, HDPE rotational molding cov ntaub ntawv muaj nyob rau hauv cov qib nkauj xwb thiab txhawb kev siv cov additives, stabilizers, thiab pigments.
