Patinotaura nezve "chinhu chakasimba kwazvo pasi pano," vanhu vazhinji vachiri kufunga nezvedhaimani kana simbi inodziya. Asi mune zvesainzi yezvinhu zvemazuva ano, kune polymer yakachinja chinyararire miganhu yefizikisi. Ultra-High Molecular Weight Polyethylene (UHMWPE) haisi purasitiki chete; imhando yepamusoro yemamorekuru. Yakasimba paundi imwe neimwe kupfuura simbi kagumi neshanu, asi yakareruka zvakakwana kuti iyangarare pamusoro pemvura.
KuHuidun UHMWPE, chinangwa chedu ndechekushandisa mukana uyu wemamorekuru mumabasa emaindasitiri, emugungwa, uye ekudzivirira. Kuti tinyatsonzwisisa kuti sei mafiber edu achiita basa rawo, tinofanira kutarisa kupfuura pamusoro uye kupinda muchimiro chidiki chepolymer pachayo.
Chinhu Chinonzi "Molecular Weight"
Chakavanzika cheUHMWPE chiri muzita rayo: "Ultra-High Molecular Weight." Kunyange zvazvo polyethylene yakajairika (rudzi rwunoshandiswa mumabhegi epurasitiki kana mabhodhoro) ine molecular mass iri pakati pe20,000 ne300,000 g/mol, UHMWPE ine molecular mass iri pakati pe3.5 ne7.5 miriyoni g/mol.
Fungidzira ndiro yezvidimbu zvipfupi zvetambo uchienzaniswa nendiro yetambo dzakareba makiromita akawanda. Kana ukaedza kuzviparadzanisa, tambo pfupi dzinofamba dzichipfuurana zviri nyore. Zvisinei, cheni dzakareba zvikuru dziri muUHMWPE dzinobatana zvakanyanya zvekuti dzinogadzira nzvimbo yakakura yepakati pemamorekuru. Kureba kwecheni uku kwakanyanya ndicho chikonzero chikuru chinoita kuti zvinhu zvigone kumira zvakasimba pasina kutyoka.
Kutenderera kweGel: Kushandura Mvura kuita Simba
Kuva ne "long molecular chains" inongova hafu yehondo. Kuti ichinje iyi "raw polymer" kuita "fiber" inoshanda zvakanyanya, inofanira kuitwa nenzira yakasarudzika inonzi "Gel Spinning". Pazvivako zvedu zvekugadzira zveHuidun, iyi inhanho yakakosha apo sainzi inosangana nekugadzira.
Mashandiro Anoita Kutenderera kweGel: Iyo UHMWPE polymer inonyungudutswa mu solvent kuti iite gel-like state. Mumamiriro aya, cheni dze polymer dzinosunungurwa zvishoma. Sezvo gel ichiburitswa kuburikidza ne spinneret, cheni dzinodhonzwa uye dzinonanga kune rimwe divi. Munguva yekutonhodza nekutambanudza kunotevera, cheni idzi dzinozvibatanidza zvakakwana ne fiber axis.
Maumbirwo aya "akanyatsorongeka" ndiwo anosiyanisa UHMWPE nemamwe mapurasitiki. Nekuti anenge macheni ese emamorekuru akatarisana nefaibha, mutoro wacho unogoverwa zvakaenzana pamusana wese wemamorekuru wepolymer. Paunodhonza faibha yeHuidun UHMWPE, unenge uchidhonza zvinobudirira pazvisungo zvecarbon-carbon.
Crystallinity uye Van der Waals Forces
Kunze kwekunge iri nyore, UHMWPE yakaita sekristalline zvakanyanya. Mumapurasitiki mazhinji, mamorekuru acho haana kurongeka uye "haana chimiro." Mumafiber eUHMWPE, anopfuura 80% echimiro chacho akarongwa mugirazi rakanyatsorongeka. Kuwanda uku kunobvumira masimba eVan der Waals akawanda—zvinokwezva zvemagetsi zviri pakati pemamorekuru—kubata. Kunyange zvazvo chisungo chimwe cheVan der Waals chisina simba, mamiriyoni acho anoshanda neketani yemamorekuru ine mayuniti manomwe anogadzira chisungo chinonetsa zvikuru kutsemuka.
Kutora Simba: Mupendero weBallistic
Chimwe chezvinhu zvinoshamisa zveUHMWPE kugona kwayo kupinza nekuparadzira simba. Nekuti kumhanya kweruzha kuburikidza neiyi polymer yakatarisana zvakanyanya kwakanyanya, simba rinobva pakurovera (senge bara kana banga rakapinza) rinotamiswa kuburikidza nefiber network nekukurumidza kupfuura zvinogona kupinda mukati mechinhu chacho.
Ndosaka UHMWPE iriyo inonyanya kushandiswa pakugadzira nhumbi dzemazuva ano dzekudzivirira muviri uye magirovhosi anodzivirira kuchekwa. Haingomisi chinhu chete; inochibata nekuparadzira simba munzvimbo yakakura, ichideredza "kushanduka kwemashure" uye kuwedzera mwero wekurarama kwemunhu akapfeka. KuHuidun, tinogadzirisa kusimba kwefiber yedu kuti tive nechokwadi chekuti kupararira kwesimba uku kwakaenzana pabhechi rega rega.
Kusadzivirira Kwakatipoteredza
Maumbirwo emakemikoro eUHMWPE haashande zvachose. Sezvo yakaumbwa nekabhoni nehydrogen chete mucheni yakazara, hapana "nzvimbo dzisina simba" dzemakemikari kana hunyoro kuti dzirwiswe. Haina mvura, zvichireva kuti haitore mvura, uye haibatanidzwi nekuora kwezvinhu zvipenyu kunokanganisa shinda dzechisikigo. Ingave yakatarisana nemwaranzi yeUV yakaoma murenje kana munyu wakapfapfaidzwa pakati pegungwa, kusimba kwemamorekuru eHuidun fiber hakuchinji.
