Chii chinonzi Ultra-High Molecular-Weight Polyethylene (UHMWPE)

Polyethylene ndiyo ipurasitiki inonyanya kushandiswa munyika, asi unoziva sei kana iri shinda chaiyo yekushandisa kwako?Funga nezvehunhu hwe-ultra-high-molecular-weight polyethylene (UHMWPE) - subset yakaoma kwazvo ye polyethylene ine simba rehuremu reshiyo ka8-15 kupfuura simbi.

Anonyanya kuzivikanwa nemazita ekutengesa eSpectra® neDyneema®, UHMWPE mapurasitiki neshinda anonyanya kushandiswa ku:

· Ballistic kushandiswa (Muviri Wezvombo, Armor Plating)

· Mitambo uye nhandaro (skydiving, skiing, boating, hove)

· Tambo uye tambo

· Kubata zvinhu zvakawanda

· Porous zvikamu uye sefa

· Indasitiri yemotokari

· Indasitiri yemakemikari

· Chikafu kugadzira uye zvinwiwa muchina

· Migodhi uye zvicherwa zvekugadzira michina

· Manufacturing midziyo

· Civil engineering uye zvekugadzira pasi

· Zvishandiso zvine chekuita nekutakura, zvinosanganisira tireyi dzerori, mabhini uye hopper.

Sezvauri kuona UHMWPE ine dzakasiyana siyana dzekushandisa kubva mukugadzira kuenda kukurapa pamwe newaya uye tambo dzekushandisa.Izvi zvinokonzerwa nerondedzero yayo refu yemabhenefiti inosangana nezvinodiwa kune akawanda akasiyana mabasa.

Zvakanakira zveUHMWPE zvinosanganisira, asi hazvina kugumira ku:

· Yakanakisa kuramba kushushikana uye yakakwirira inopokana nekutsemuka

· Abrasion kupfeka kuramba - kanokwana gumi neshanu kusagadzikana kune abrasion pane kabhoni simbi

· Yayo 40% Yakasimba kudarika Aramid yarn

· Kupokana kwayo kwemakemikari - kusimba zvakanyanya kune akawanda alkalis uye asidhi, organic solvents, degreasing agents uye electrolytic kurwisa.

· Haina chepfu

· Yakanakisa dielectric zvivakwa

· Kuzvizora-kuzora - yakaderera kwazvo coefficient yekukwesha (inofananidzwa nePTFE)

· Kusasvibisa

· FDA yakatenderwa kushandiswa muchikafu nemishonga yekurapa

· Kudzika kwakananga giravhiti - ichayangarara mumvura

Kunyange izvi zvichinzwika sechinhu chakakodzera, pane zvakare mashoma mashoma aunofanirwa kuziva.UHMWPE ine nzvimbo yakaderera yekunyungudika (297 ° kusvika 305 ° F) kupfuura akawanda akajairwa mapolymer, saka haina kukodzera kune yakanyanya kupisa tembiricha.Iyo ine zvakare yakaderera coefficient ye friction iyo inogona kuva drawback zvichienderana nekushandisa.UHMWPE yarns inogona zvakare kukudziridza "inokambaira" pasi pemutoro unogara uripo, inova maitiro ekurebesa zvishoma nezvishoma kwemafibhi.Vamwe vanhu vanogona kuona mutengo sechinhu chinokanganisa, zvisinei kana zvasvika kuUHMWPE, zvishoma zvakanyanya.Nekusimba kwechinyorwa ichi haungade kutenga zvakanyanya sezvaungaite nezvimwe zvinhu.
