Kwimizi-mveliso yanamhlanje, ukwenziwa kwesinyithi, ukuhlanganiswa kweemoto, kunye nokulungiswa kweglasi enzima, ukwenzakala kwezandla kusephakathi kwezona zinto ziyingozi kakhulu emsebenzini. Kangangamashumi eminyaka, abaphathi bokhuseleko babexhomekeke kwisikhumba esinzima, imixube yekotoni erhabaxa, okanye izinto ezenziwe nge-aramid zesizukulwana sokuqala ukubonelela ngokhuseleko olusisiseko kwiingcango ezibukhali, ii-metal burrs, kunye noomatshini bokucheba. Nangona ezi zinto zazibonelela ngesiseko sokuzikhusela, zabonisa urhwebo olukhulu ngobunzima, ubunzima bomzimba, kunye nobuchule bezandla.
Namhlanje, utshintsho olukhoyo luguqula ishishini lezixhobo zokuzikhusela zomntu (PPE). Ukwamkelwa ngokubanzi kwefayibha ye-Ultra-High Molecular Weight Polyethylene (UHMWPE) kubhala ngokutsha imigangatho yokhuseleko lwezandla zoshishino. Ukudibanisa amandla okuxinana kakhulu nobunzima obuphantsi, ifayibha ye-UHMWPE ivumela abavelisi beglavu ukuba bavelise i-PPE ekhaphukhaphu, eguquguqukayo efikelela kumandla okunqunyulwa aphezulu ngaphandle kokunciphisa intuthuzelo yomntu onxibe okanye ulawulo lwemoto.
Olu hlalutyo lobuchwephesha luhlola isayensi yezinto ezisetyenziswayo emva kwefayibha ye-UHMWPE, indlela eyichaza ngayo ngokutsha imigangatho yamazwe ngamazwe yokumelana nokunqunyulwa, kunye nesizathu sokuba ibe yinto ekhethwayo kwiiglavu zokhuseleko eziphezulu.
I-Molecular Blueprint: Yintoni Eyenza I-UHMWPE Fiber Cut-Resistant?
Ukuze siqonde ukuba kutheni i-UHMWPE fiber inika ukumelana okuphezulu kangaka, kufuneka sihlolisise uyilo lwayo lweemolekyuli. Ngokungafaniyo ne-polyethylene eqhelekileyo, ene-branched, short-chain polymer links, i-UHMWPE inee-chain ezinde kakhulu, ezingenamasebe ze-polymerized ethylene. Ezi -molecular chain zinobunzima be-molecular obuphakathi kwe-3.5 kunye ne-7.5 yezigidi zeeyunithi zobunzima be-athomu.
Ngexesha lenkqubo ekhethekileyo yokwenziwa kwejeli, la matyathanga amakhulu epolymer alungelelaniswe kwi-axis ende yefayibha. Olu didi luphezulu lokuqhelaniswa kunye ne-crystallization ludala ulungelelwaniso oluhle kakhulu oluhambelanayo, oluvumela uxinzelelo lwangaphandle lomzimba ukuba lusasazeke ngokulinganayo kulo lonke ulwakhiwo lwe-molecular. Ngokwesiseko sobunzima-ngobunzima, olu lungelelwaniso lwe-molecular lwenza i-UHMWPE fiber ibe namandla ngokuphindwe ka-15 kunentsimbi yesakhiwo kwaye ikwazi ukumelana kakhulu nokukrala kunye namandla okuchaphazela kune-aramid fibers eqhelekileyo.
Iindlela Zokusika Ingozi:Xa i-blade ebukhali okanye umphetho wesinyithi ubetha iglavu ethungwe ngefayibha ye-UHMWPE, amandla aphezulu okuxinana athintela i-blade ukuba ibambe kwaye inqumle kwi-filaments nganye. Endaweni yoko, umphezulu otyibilikayo, ongaphantsi kwe-froction ye-polymer uvumela umphetho obukhali ukuba utyibilike phezu kwe-weave, usasaze amandla oomatshini kwindawo ebanzi endaweni yokuwajolisa kwindawo enye yokusilela.
Ukuchaza ngokutsha iMigangatho yeHlabathi: Iiprofayili zokusebenza ze-ANSI kunye ne-EN388
Icandelo lokhuseleko lwemizi-mveliso livavanya ukusebenza kweeglavu ngokusekelwe kwiinkqubo ezimbini eziphambili zovavanyo lwamazwe ngamazwe: umgangatho waseMntla Melika we-ANSI/ISEA 105 kunye nomgaqo-nkqubo we-European EN 388. Zombini ezi migangatho zilinganisa ubungakanani bamandla afunekayo ukuze i-blade yoomatshini inqumle ilaphu lesampulu phantsi kweemeko ezilawulwayo.
Ngokwembali, ukufumana amanqaku aphezulu (njenge-ANSI Cut Level A4 ukuya kwi-A6, okanye i-EN388 Levels D kunye ne-E) kwakufuna iileya ezijiyileyo nezinkulu zelaphu elilukiweyo, elihlala liqiniswa nge-fiberglass ebuthathaka okanye ii-cores zentsimbi enzima. Ezi zakhiwo zidibeneyo zazidla ngokucaphukisa ulusu kwaye zibangele ukudinwa kwezandla, nto leyo eyabangela ukuba abasebenzi bakhuphe iiglavu zabo kwaye bonyuse umngcipheko wokwenzakala.
Ifayibha ye-UHMWPE iyitshintshile le ndlela. Ngokusebenzisa imisonto ye-UHMWPE enganyangekiyo kakhulu, abavelisi banokufikelela kumanqanaba aphezulu okusika i-ANSI ngee-knits ezine-single-layer, ezine-high gauge (ezifana nee-15-gauge okanye ii-18-gauge shells). Oku kubonelela ngeenzuzo ezininzi zokusebenza eziphambili:
Ulwazelelelo lokuThatha oluphuculweyo:Abasebenzi banokukwazi ukuphatha izinto zokubopha ezincinci, izixhobo ze-elektroniki ezincinci, kunye nezixhobo ezichanekileyo ngaphandle kokususa iiglavu zabo zokhuseleko.
Ukudinwa Kwesandla Esisezantsi:Ukuguquguquka kwe-UHMWPE kuvumela iglavu ukuba ivumelane ngokwemvelo nokwakheka kwesandla, nto leyo enciphisa ukuxhathisa ngexesha lokubambelela ngokuphindaphindiweyo.
Intuthuzelo Ephuculweyo Yobushushu:I-UHMWPE inomoya ophezulu wokuhambisa ubushushu, nto leyo evumela ubushushu obuvela esandleni ukuba buphele ngokukhawuleza. Oku kugcina izandla zipholile kwaye zikhululekile xa zitshintshana ixesha elide xa kuthelekiswa nezinto zokwenziwa ezibamba ubushushu.

Ixesha Elide Lokusebenza kunye Nokusebenza Kakuhle Kweendleko
Ngaphandle kweenzuzo zayo zokhuseleko olukhawulezileyo, abaphathi bokhuseleko kwimizi-mveliso bakhetha ifayibha ye-UHMWPE ngenxa yokuba igcina iindleko zayo zisebenza kakuhle ixesha elide. Kwiindawo ezinzima kwimizi-mveliso, iiglavu zomsebenzi zichatshazelwa ziioyile, iigrisi, izinyibilikisi, kunye nemijikelo yokuhlamba impahla rhoqo.
Iiglavu ezininzi ezisekelwe kwi-aramid ziyawohloka xa zichatshazelwa kukufuma kunye neesepha zoshishino, zilahlekelwa yipesenti yeempawu zazo ezichasene nokunqunyulwa kwimijikelo nganye yokuhlamba impahla. Ngokwahlukileyo koko, ifayibha ye-UHMWPE ayinayo ikhemikhali kwaye ayifuni manzi ngokupheleleyo. Ayifunxi amanzi, iioyile, okanye izisombululo zokucoca iikhemikhali. Iiglavu ezenziwe ngefayibha ye-UHMWPE ephezulu zinokuhlanjwa ngokuphindaphindiweyo ngaphandle kokuncipha, ukulahlekelwa ngamandla okutsalwa, okanye ukuphazamisa amanqaku azo okunciphisa e-ANSI/EN388. Olu bomi bude bokusebenza bunciphisa ukuphindaphindwa kokutshintshwa, kunciphisa iindleko zokuthenga ze-PPE ngokubanzi kumashishini amakhulu emizi-mveliso.
