Uhmwepe vs. HDPE: uas yog rau koj qhov project?

Thaum xaiv cov ntaub ntawv, nws yog qhov tseem ceeb kom nkag siab txog cov khoom thiab daim ntawv thov cov xwm txheej ntawm ntau txoj kev xaiv. Rau ntau lub tshuab engineering thiab kev tsim khoom lag luam, UHMWPE (ultra-high-high-high-high-ntom polyethylene) yog ob hom khoom yas. Txawm li cas los xij, qhov sib txawv ntawm lawv tuaj yeem cuam tshuam cov kev ua tau zoo, durability, thiab tus nqi ntawm ib qhov project. Yog tias koj tau txiav txim siab cov no ob cov ntaub ntawv, nkag siab txog lawv qhov sib txawv tseem ceeb yuav ua rau koj txiav txim siab zoo rau koj cov kev xav tau. Hauv tsab xov xwm no, peb yuav delve rau hauv qhov txawv ntawm HDPE thiab UHMWPE los pab koj xaiv cov khoom tsim nyog.

Dab tsi yog Uhmwpe?

UHMWPE (ultra-high-molecular-phaus polyethylene)Yog ib qho kev ua tau zoo engineering yas nrog lub phaus molecular heev, tshaj ib lab. Nws cov qauv molecular xaus rau nws nrog cov coj hnav tsis kam, cuam tshuam, thiab ib qho tsis tshua muaj kev sib txhuam ntawm kev sib txhuam. UHMWPE tau siv dav hauv cov ntawv thov kom muaj zog, xws li muaj cov cuab yeej siv kho mob, thiab khoom siv kho mob, khoom siv pob ncaws pob, thiab lwm thaj chaw.

HDPE yog dab tsi?

HDPE (high-ntom polyethylene) yog ib qho uas nquag siv hluav taws xob nrog cov qauv molecular, muab siab ceev thiab lub zog siab. Nws yog resistant rau tshuaj corrosion, muaj cov uv tsis kam, thiab muaj cov roj thiab lub zog zoo. Cov kev siv cov tshuaj yas ntim cov khoom siv yas, ntim khoom, ntim zaub mov, thiab lwm yam.

Molecular qauv thiab molecular hnyav

UHmwpe yog qhov hnyav-molecular-phaus thermoplastic, nrog molecular hnyav li feem ntau yog kwv yees li 3 lab mus rau 9 lab. Nws cov chains ntev molecular muab nws cov cuab yeej zoo heev, hnav tsis kam, thiab tawv. Lub siab dua cov qauv molecular, qhov ntau ruaj khov nws cov crystal cov qauv thiab cov khoom muaj zog ntawm cov khoom muaj zog, cuam tshuam tsis kam, thiab qaug zog tsis kam.
HDPE muaj qhov hnyav dua molecular, feem ntau yog ib txwm muaj zog, nws yog cov roj ntsha ua kom luv dua thiab cov coj tsis zoo piv rau UHMWPE. Txawm li cas los xij, HDPE muaj kev ua tau zoo dua, yog tsim nyog rau kev tsim khoom loj, thiab muaj kev cuam tshuam zoo.

Coefficient ntawm kev sib txhuam thiab hnav tsis kam

UHMWPE muaj qhov qis heev coefficient ntawm kev txhuam hniav, feem ntau ntawm {{}}}}}}}. Nws cov coj tsis kam deb deb ntawm HDPE. Kev sim cov ntaub ntawv qhia tau tias cov hnav tus nqi ntawm UHMWPE tsuas yog hais txog 1/10 uas yog qhov qis dua, ua rau nws nyob hauv cov ntawv thov High-thauj khoom thiab cov hlua khau khiab.
HDPE muaj cov coefficient ntawm kev sib txhuam, nyob ib ncig 0. 30, ua rau nws cov coj tsis kam yog qis dua ntawm UHMWPE. Txawm li cas los xij, HDPE tseem tuaj yeem ua rau muaj kev ruaj khov nyob rau hauv cov khoom siv tsis muaj zog, tshwj xeeb yog siv rau cov khoom siv txhua hnub, cov khoom xa mus rau lwm qhov chaw uas nws ua tau zoo.

Lub zog tensile thiab tawv ncauj

Lub zog tensile ntawm UHMWPE feem ntau yog li ntawm 35 txog 50 MPA. Tshwj xeeb tshaj yog nyob rau hauv qis-qhov chaw ib puag ncig, nws tseem tuaj yeem tswj kev nruj thiab cuam tshuam tsis tau zoo heev. Nws elongation thaum tawg tuaj yeem tshaj 300%, lub ntsiab lus nws tsis zoo li yuav tawg rau hauv nro. Qhov no ua rau nws haum rau kev cuam tshuam ntau, cov kev siv hluav taws xob hag-zoo li cov pob qij txha kho mob), cov hlua hluav taws xob, cov hlua khi, thiab lwm yam.
Lub zog tensile ntawm HDPE feem ntau ntawm 25 thiab 40 MPa, ua rau nws haum ntau rau kev siv dav dav. Txawm hais tias nws lub cev tawv tsis zoo li ntawm Uhmwpe, HDPE muaj cov ntawv thov engineent zoo dua, xws li hauv cov kav dej yas, ntim, thiab lwm thaj chaw.

Tshuaj lom neeg ruaj khov thiab corrosion tsis kam

UHMWPE Cov Tshuaj Nyab Xeeb Kev Ruaj Ntseg, muaj peev xwm ntawm kev xeb ntawm cov ntau acids, alkalis, ntsev cov kuab tshuaj, thiab cov kuab tshuaj organic. Kev sim cov ntaub ntawv qhia tau tias UHMWPE tuaj yeem tswj tau ruaj khov ntawm cov sulfuric acid, thiab ammonia yam tsis muaj kev hloov pauv ntawm lub cev tseem ceeb.
HDPE kuj muaj cov zoo corrosion tsis kam, tab sis nws tsis tshua tiv taus ntau dua UHMWPE. Txawm hais tias nws tuaj yeem tiv thaiv cov kua qaub-cov tshuaj-cov kev daws teeb meem thiab cov kuab tshuaj, HDPE yuav tawg thaum raug cov kuab tshuaj hydrocarbons thiab chlorinated hydrocarbons.

Kub tiv thaiv

UHMWPE muaj qhov kub thiab txias tsis kam ntau, muaj peev xwm ntawm nrog kev sib txawv ntawm kev sib txawv ntawm -200 degree rau 80 degree. Nws cov tawv tshwj xeeb tshwj xeeb tshwj xeeb tshaj yog thaum kub tsawg. Nyob rau hauv ib puag ncig txias heev, nws lub zog thiab kev cuam tshuam tsis tau, ua rau nws haum rau hauv ib puag ncig txias lossis qis dua kev ua haujlwm tsawg. Qhov kub tsis kam ntawm HDPE feem ntau yog qhov nqaim, feem ntau yog {{}} degree thiab 60 degree. Thaum kub siab, cov neeg kho mob tshuab hluav taws xob ntawm HDPE yuav tsis zoo, tshwj xeeb tshaj yog 60 degree, qhov twg hdpe muag muag thiab poob nws lub zog qub.

Ua thiab nqi

UHMWPE yog qhov nyuaj los ua haujlwm vim nws lub siab molecular hnyav, uas cov khoom siv yas ua tau tsis tuaj yeem siv. Cov txheej txheem ua tshwj xeeb thiab cov khoom siv tshwj xeeb (xws li kub-kub compression moulding) yog qhov yuav tsum tau ua. Yog li ntawd, tus nqi ntawm UHMWPE siab dua, ua rau nws haum rau cov ntawv thov kev lag luam qib siab thiab tshwj xeeb.
HDPE yooj yim dua rau cov txheej txheem thiab tuaj yeem hloov kho cov txheej txheem ua tiav yas, suav nrog kev txhaj tshuaj molding thiab extrusion molding. Nws tus nqi ua yog qis dua, thiab vim muaj ntau cov ntaub ntawv raw thiab cov txheej txheem ntau lawm, tus nqi ntawm HDPE yog qis dua li UHMWPE.

Daim Ntawv Thov

UHMWPE tau siv dav hauv cov liaj teb uas yuav tsum muaj cov khoom siv tsis tshua muaj, xws li siv cov khoom siv sib xyaw ,, UHMWPY, CARTECHOR siv nyiaj, casting pwm, khoom sib koom ua ke, thiab lwm yam.
HDPE tau dav hauv lub neej txhua hnub, tshwj xeeb hauv kev ntim, cov kav yas, ntim, khoom siv hauv tsev, thiab lwm thaj chaw. Nws cov tshuaj zoo heev thiab UV tiv taus ua nws cov khoom zoo tagnrho rau cov kav dej yas thiab ntim khoom cia.
