Izakhiwo ezinhle kakhulu ze-UHMWPE fiber

Ifayibha ye-UHMWPE inezinto eziningi ezinhle kakhulu, njengezakhiwo ezinhle kakhulu zemishini, ukumelana nomthelela omuhle kakhulu, ukumelana nokugqokwa okuhle kakhulu, ukumelana nokugqwala kwamakhemikhali, ukumelana nokukhanya okuhle kakhulu nokunye.

1. Izakhiwo ezinhle kakhulu zemishini ye-UHMWPE fiber.

Ifayibha ye-UHMWPE inezakhiwo ezinhle kakhulu zemishini. Ngaphansi kokuminyana komugqa ofanayo, amandla aqinile e-UHMWPE fibre aphindwe izikhathi ezingu-15 kunawentambo yocingo lwensimbi. Iphakeme ngo-40% kune-aramid fiber, ephinde ibe ngenye yezintambo ezintathu zobuchwepheshe obuphezulu emhlabeni, futhi iphakeme ngokuphindwe ka-10 kune-high quality fiber fiber kanye ne-chemical fiber evamile. Uma kuqhathaniswa nensimbi, i-E-glass, inayiloni, i-polyamine, i-carbon fiber kanye ne-boron fiber, amandla ayo kanye ne-modulus kuphakeme kunaleyo yale micu, futhi amandla ayo aphakeme kakhulu phakathi kwezinto ezisezingeni elifanayo.

2.Ukumelana nomthelela omuhle kakhulu we-UHMWPE fiber

I-Ultra high molecular weight polyethylene fiber inokumelana nomthelela omuhle kakhulu. Amandla ayo okumunca amandla futhi amelane nomthelela ngesikhathi sokuguquguquka nokubumba aphakeme kunalawo e-aramid fiber kanye ne-carbon fiber, okuphinde kube "imicu emithathu yobuchwepheshe obuphezulu emhlabeni". Uma kuqhathaniswa ne-polyamide, i-aramid, i-E glass fiber, i-carbon fibre kanye ne-aramid fibre, i-UHMWPE fiber inokumunca ingqikithi yamandla ngaphezu komthelela.

3. Ukumelana okuhle kokugqoka kwe-UHMWPE fiber

Ngokuvamile, uma i-modulus enkulu yezinto ezibonakalayo, iyancipha ukumelana nokugqokwa, kodwa ku-fiber ye-UHMWPE, okuphambene kuyiqiniso. Ngenxa yokuthi ifayibha ye-UHMWPE ine-coefficient ephansi yokungqubuzana, uma imodulus iba nkulu, kuphakama ukumelana nokuguga. Uma kuqhathaniswa i-friction coefficient ye-UHMWPE fibre naleyo ye-carbon fibre ne-aramid fiber, ukumelana nokugqokwa nokukhathala kwe-UHMWPE fiber kuphezulu kakhulu kunaleyo ye-carbon fibre kanye ne-aramid fiber. Ngakho ukumelana kwayo nokugqoka kungcono kuneminye imicu ephezulu yokusebenza. Ngenxa yokumelana nokugqoka okuhle kakhulu nokumelana nokugoba, ukusebenza kwayo kokucubungula nakho kuphakeme, futhi kulula ukwenziwa kwezinye izinto eziyinhlanganisela nezindwangu.

I-4.Chemical corrosion resistance of UHMWPE fiber

Isakhiwo samakhemikhali se-UHMWPE fiber silula futhi izakhiwo zayo zamakhemikhali azinzile. Ngaphezu kwalokho, ine-orientation yesakhiwo se-crystalline kakhulu, okwenza ingabi sengozini yokuhlaselwa kwezakhi zofuzo ezisebenzayo kuma-acids aqinile nezisekelo eziqinile, futhi ingagcina izakhiwo zayo zamakhemikhali zangempela kanye nesakhiwo. Ngakho-ke, amakhemikhali amaningi akulula ukuwagqwalisa. Izixazululo ezimbalwa ze-organic kuphela ezingayikhukhumeza kancane, futhi ukulahleka kwayo kwempahla kungaphansi kuka-10%. Ukugcinwa kwamandla kwefayibha ye-UHMWPE nefayibha ye-aramid kumidiya ehlukene yamakhemikhali kwaqhathaniswa. Ukumelana nokugqwala kwefayibha ye-UHMWPE ngokusobala kungaphezulu kwalokho kwefayibha ye-aramid. Izinzile ikakhulukazi ku-asidi, i-alkali nosawoti, futhi amandla ayo alahleka kuphela kusisombululo se-sodium hypochlorite.

I-5.Ukumelana nokukhanya okuhle kakhulu kwe-fiber ye-UHMWPE

Ngenxa yokuthi ukwakheka kwamakhemikhali e-UHMWPE fibre izinzile, ukumelana kwayo nokukhanya kuphinde kube kuhle kakhulu phakathi kwemicu yobuchwepheshe obuphezulu. I-Aramid fiber ayimelani ne-UV futhi ingasetshenziswa kuphela ngaphansi kwesimo sokugwema ukukhanya kwelanga okuqondile. Uma kuqhathaniswa nefayibha ye-UHMWPE enayiloni, i-aramid ene-modulus ephezulu kanye ne-modulus ephansi, ukugcinwa kwamandla kwe-UHMWPE fiber kuphakeme kakhulu kunokweminye imicu.

6.Ezinye izakhiwo ze-UHMWPE fiber

Ifayibha ye-UHMWPE futhi inempahla enhle ye-hydrophobic, ukumelana kwamanzi nomswakama, impahla yokufaka ugesi kanye nempilo ende ehlukumezayo. Iwukuphela kwefayibha yobuchwepheshe obuphezulu ekwazi ukuntanta emanzini, futhi iyimpahla efanelekile enezinga lokushisa eliphansi.

Kodwa futhi inebubi bayo, okungukuthi, indawo yokuncibilika iphansi. Ngesikhathi sokucubungula, izinga lokushisa akufanele lidlule ku-130 ℃, ngaphandle kwalokho, into ekhasayo izokwenzeka futhi impilo yesevisi izofushaniswa ngenxa yamandla abuthakathaka phakathi kwamaketanga e-molecular of UHMWPE fibers. Alikho iqembu likadayi kwifayibha ye-UHMWPE, eyenza ukumanzi kwayo kube kubi. Kunzima ukuthi udayi ungene ku-fiber, okuholela ekusebenzeni kabi kokudaya. Lokhu kushiyeka kuthinta ububanzi bokusebenza kwayo.
