Kwihlabathi lezinto eziphucukileyo, amagama amabini alawula incoko xa kufuneka amandla, ukuqina, kunye nokhuseleko:I-Polyethylene enobunzima obuphezulu kakhulu (UHMWPE)kwayeI-Aramid (edla ngokuqatshelwa ngamagama emveliso afana neKevlar® okanye iTwaron®)Zombini zizinto ezimangalisayo zobunjineli, kodwa azinakutshintshwa. Ukukhetha engalunganga kwisicelo sakho esithile kunokukhokelela ekusileleni kwangethuba okanye kwiindleko ezingeyomfuneko.
At I-Huidun UHMWPE, sigxile ekutyhaleleni imida yetekhnoloji yefayibha ye-polyethylene. Nangona kunjalo, sikholelwa ekunikeni abathengi bethu umbono ocacileyo wendlela ezi zinto ezihlanganiswa ngayo. Kule khokelo, siza kungena nzulu kwiingxaki zobugcisa, iingenelo, kunye nemida yazo zombini iifayibha ukukunceda wenze isigqibo sokuthenga esinolwazi.
Iziseko: Zithini?
Ukuze siqonde ukusebenza kwazo, kufuneka sijonge i-DNA yazo yemolekyuli. I-UHMWPE yi-polyolefin eyenziwe ngeetsheyini ezinde kakhulu ze-polyethylene. Ezi tsheyini zihambelana kwicala elinye, zenza izinto apho amandla aphakathi kweemolekyuli enziwa ngcono, nto leyo ephumela kwifayibha enamandla kakhulu kodwa ekhaphukhaphu ngokwaneleyo ukuba intante emanzini.
Kwelinye icala, i-Aramid yi-polyamide eyenziweyo enuka kamnandi. Ulwakhiwo lwayo lwe-molecular lunezangqa eziqinileyo ezidityaniswe ziibhondi ze-hydrogen ezinamandla. Oku kwenza i-Aramid imelane kakhulu nobushushu kunye neekhemikhali, kodwa inika uxinano oluphezulu kune-polyethylene yayo.
Umlinganiselo Wokuqina Kobunzima: Iqhawe Elilula
Ukuba iprojekthi yakho ifuna amandla aphezulu kangangoko ngobunzima obuphantsi kangangoko,I-UHMWPE yeyona iphumeleleyo ngokucacileyoIthathwa ngokubanzi njengeyona fiber inamandla ehlabathini xa kuthelekiswa nobunzima—inamandla ngokuphindwe kalishumi elinesihlanu kunentsimbi kwaye inamandla kakhulu kuneefiber ze-Aramid.
Ngenxa yokuba i-UHMWPE inobunzima obungaphantsi kwe-1.0 g/cm³, iyadada. Oku kuyenza ibe ngumgangatho olungileyo wokusetyenziswa elwandle, njengeentambo zokubopha iinqanawa ezinzulu kunye neentambo zokutsala. I-Aramid, nangona inamandla, inzima malunga ne-40% kwaye iya kutshona emanzini. Kwimizi-mveliso efana neenqwelo-moya okanye izixhobo zokuzikhusela apho igram nganye ibalwa khona, ukonga ubunzima okunikezelwa ziifayibha ze-UHMWPE ezivela kwiHuidun kunokuba yinto etshintsha umdlalo.
Uzinzo lobushushu: Apho i-Aramid ikhanya khona
Isithende sika-Achilles se-UHMWPE bubuthathaka bayo kubushushu. Njengoko iyi-thermoplastic, i-UHMWPE iqala ukuthamba malunga nama-80°C ukuya kwi-100°C ize inyibilike malunga nama-144°C ukuya kwi-152°C. Oku kunciphisa ukusetyenziswa kwayo kwiindawo apho ukuvezwa kobushushu obuphezulu kuhlala kuhleli, njengezixhobo zokulwa nomlilo okanye iibhanti zoshishino ezixineneyo.
I-Aramid yikumkani engenakuphikiswa yokumelana nobushushu. Ayinyibiliki; endaweni yoko, inyibilika kwi-carbonizes kumaqondo obushushu angaphezulu kwama-400°C. Ukuba ukusetyenziswa kwakho kubandakanya ilangatye elithe ngqo, ukungqubana kobushushu obuphezulu, okanye iindawo ezishushu kakhulu, i-Aramid isenokuba lolona khetho lungcono. Nangona kunjalo, kwiindawo ezininzi zangaphandle, kwezobugcisa, nakwimizi-mveliso apho amaqondo obushushu ehlala ngaphakathi komgangatho oqhelekileyo, ukusebenza kwe-UHMWPE kuhlala kuphezulu.
Ukuqina, Ukufuma, kunye nokumelana neekhemikhali
Kwiimeko zokwenyani, izinto ezingqongileyo zihlala zilawula ubomi bezinto eziphathekayo. Kulapho keI-UHMWPE iyagqwesakakhulu ngaphezu kwe-Aramid:
Ukukhusela i-Abrasion kunye ne-Impact
Kwizixhobo zokukhusela i-ballistic kunye nezixhobo ezinganyangekiyo, zombini ezi zinto zisetyenziswa kakhulu, kodwa zibonelela "ngeemvakalelo" ezahlukeneyo kunye neeprofayili zokusebenza. I-UHMWPE ine-coefficient ephantsi kakhulu yokungqubana, nto leyo eyenza ivakale "ithambile". Oku kuyenza isebenze kakuhle kakhulu ekutyibilikeni kwiindawo ezirhabaxa, nto leyo ekhokelela ekuchaseni okuphezulu kokuguguleka kwiintambo kunye nemikhono yemizi-mveliso.
Kwizicelo ze-ballistic (ezifana neevesti ezikhusela iimbumbulu), i-UHMWPE idla ngokukhethwa ngenxa yokukwazi kwayo ukusasaza amandla ngokukhawuleza kuthungelwano lwefayibha, inika ukhuseleko oluhle kakhulu kwiziqwenga zesantya esiphezulu ngelixa ilula kakhulu ukuba umntu oyinxibileyo ayithwale. I-Aramid isaxatyiswa ngenxa yokuqina kwayo kunye nokumelana nokubhoboza, kodwa umkhwa weshishini usiya kwi-UHMWPE-based composites kwizixhobo zanamhlanje nezikhaphukhaphu.
