Polyethylene ke polasetiki e sebelisoang haholo lefatšeng, empa u tseba joang hore na ke khoele e nepahetseng bakeng sa kopo ea hau?Nahana ka litšobotsi tsa ultra-high-molek'hule-boima polyethylene (UHMWPE) - subset e thata haholo ea polyethylene e nang le matla a boima karo-karolelano ka makhetlo a 8-15 ho feta tšepe.
Tse tsebahalang ka mabitso a khoebo a Spectra® le Dyneema®, lipolasetiki le likhoele tsa UHMWPE li sebelisetsoa haholo-holo:
· Ts'ebeliso ea Ballistic (Lihlomo tsa 'mele, Plating ea Lihlomo)
· Lipapali le boikhathollo (ho tsubella moeeng, ho thellisa, ho palama likepe, ho tšoasa litlhapi)
· Lithapo le likhoele
· Ho sebetsana le thepa e ngata
· Likarolo tse porous le sefa
· Indasteri ea likoloi
· Indasteri ea lik'hemik'hale
· Mechini ea ho lokisa lijo le lino
· Lisebelisoa tsa merafo le lirafshoa
· Lisebelisoa tsa tlhahiso
· Boenjiniere ba sechaba le lisebelisoa tse tsamaisang lefatše
· Lisebelisoa tse amanang le lipalangoang, ho kenyeletsoa literei tsa literaka, meqomo le li-hopper.
Joalo ka ha u bona UHMWPE e na le mefuta e fapaneng ea ts'ebeliso ho tloha ho tlhahiso ho isa ho tsa bongaka hammoho le lits'ebetsong tsa terata le likhoele.Sena se bakoa ke lethathamo le lelelele la melemo e fihlelang litlhoko tse ikhethang bakeng sa mesebetsi e mengata e fapaneng.
Melemo ea UHMWPE e kenyelletsa, empa ha e felle feela ho:
· E babatsehang ho hanyetsa khatello ea kelello le phahameng manganga ho cracking
• Abrasion wear resistance - makhetlo a 15 a hanyetsanang le abrasion ho feta tšepe ea carbon
· E matla ho feta likhoele tsa Aramid ka 40%.
· E hanana le lik'hemik'hale tse matla - e khona ho mamella boholo ba alkali le asiti, lihlapolli tsa lintho tse phelang, li-degreasing agents le tlhaselo ea electrolytic.
· Ha e chefo
· Lintho tse ntle tsa dielectric
Ho itšehla thajana - khohlano e tlase haholo (e bapisoa le PTFE)
· Ho se silafatse
· FDA e lumelletsoe ho sebelisoa lijong le lits'ebetsong tsa bongaka
· Matla a khoheli a tlase - a tla phaphamala ka metsing
Le hoja sena se ka utloahala e le boitsebiso bo loketseng, ho boetse ho na le mefokolo e 'maloa eo u lokelang ho e ela hloko.UHMWPE e na le sebaka se tlase sa ho qhibiliha (297 ° ho isa ho 305 ° F) ho feta li-polymers tse ngata tse tloaelehileng, ka hona ha ea lokela ho sebelisoa ha mocheso o phahameng.E boetse e na le coefficient e tlase ea khohlano e ka bang tšitiso ho latela ts'ebeliso.Likhoele tsa UHMWPE li ka boela tsa “khasa” tlas’a mojaro o sa khaotseng, e leng mokhoa oa ho lelefatsa butle-butle ha likhoele.Batho ba bang ba ka 'na ba nka hore theko ke ntho e mpe, leha ho le joalo ha ho tluoa tabeng ea UHMWPE, ho fokotseha ho feta.Ka lebaka la matla a thepa ena, ha ho hlokahale hore u reke haholo joalokaha u ne u ka reka ka thepa e 'ngoe.
