Yas folding rooj vaj huam sib luag

Nrog rau kev nce qib ntawm thev naus laus zis thiab kev nce qib ntawm kev ua si sab nraum zoov,yas folding roojtau maj mam los rau hauv tib neeg pom.Nws tau yeej cov neeg nyiam rau nws qhov ntim me me, lub teeb yuag thiab yooj yim siv tom qab folding.Lub rooj folding yog tsim los ntawm ib lub vaj huam sib luag thiab ib lub thav duab.Hnub no kuv yuav qhia cov khoom ntawm lub rooj folding.

High-density polyethylene (HDPE), hmoov dawb los yog granular khoom.Non-toxic, tasteless, crystallinity ntawm 80% mus rau 90%, softening point ntawm 125 mus rau 135 ° C, kev pab kub mus txog 100 ° C;

hardness, tensile zog thiab creep zoo dua li tsawg ntom polyethylene;

hnav tsis kam, hluav taws xob zoo rwb thaiv tsev, toughness thiab txias tsis kam;

zoo tshuaj stability, insoluble nyob rau hauv tej organic solvents ntawm chav tsev kub, corrosion resistant rau acids, alkalis thiab ntau yam ntsev;

zaj duab xis muaj tsawg permeability rau dej vapor thiab huab cua, thiab dej nqus tsawg;

kev laus tsis zoo, ib puag ncig kev ntxhov siab tawg ua haujlwm tsis zoo li cov polyethylene tsawg, tshwj xeeb tshaj yog thermal oxidation yuav txo nws cov kev ua tau zoo,

yog li cov tshuaj antioxidants thiab ultraviolet absorbers yuav tsum tau ntxiv rau cov resin los txhim kho qhov tsis txaus no.

High-density polyethylene zaj duab xis muaj qhov kub thiab txias distortion kub nyob rau hauv kev ntxhov siab, yog li yuav tsum tau saib xyuas thaum siv nws.

Nyob rau hauv lub xyoo pua no, kev hloov pauv hloov pauv tau tshwm sim hauv thaj chaw ntawm cov kav dej, uas yog, "hloov hlau nrog yas".Nrog rau kev nce qib sai ntawm cov khoom siv polymer science thiab thev naus laus zis, kev sib sib zog nqus ntawm kev txhim kho thiab kev siv cov kav dej yas, thiab kev txhim kho txuas ntxiv ntawm cov cuab yeej siv, cov kav dej yas tau ua tiav lawv cov kev ua tau zoo.

Niaj hnub no, cov kav dej yas tsis tau yuam kev rau "kev hloov pheej yig" rau cov kav hlau.Hauv qhov kev hloov pauv no, cov kav dej polyethylene tau txais kev pom zoo thiab ua kom ci ntsa iab.Lawv tau siv dav hauv kev xa hluav taws xob, dej xau, dej phwj tuaj, dej ua liaj ua teb, kev thauj mus los zoo hauv cov mines, nrog rau cov roj av, tshuaj, xa ntawv thiab kev sib txuas lus, thiab lwm yam, tshwj xeeb tshaj yog nyob rau hauv cov teb xws li nws tau siv dav hauv gas tsheb thauj mus los.
