Iyini i-Velcro noma i-friction splint?

Isondo le-Friction noma i-"Velcro" iklasi lesondo lasebusika elingabambelela endaweni yeqhwa ngaphandle kokufakwa kwensimbi. Uma ku-rubber egxilile ukusebenzisana kwe-coating eshelelayo kanye nokunyathela kuhlanganisa ukungqubuzana kwerabha kanye nokunamathela kwezigxobo, khona-ke ku-friction eyodwa kuphela kusetshenziswa amandla okuphikisana.

Ukubamba kwesondo ngomgwaqo kuncike kakhulu kumashekhi wephethini yokunyathela. Uma inani labo likhulu kanye nobude obuphelele bemiphetho kusiqephu sokuxhumana, isondo lizobamba kangcono umgwaqo wasebusika. Ngesikhathi sokusheshisa, umkhawulo ongemuva we-tread block ucushiwe, ngenkathi i-braking - ngaphambili.

Izici nezimiso zenjoloba yokungqubuzana

Izici ezisebenzayo ze-Velcro zinikeza izakhiwo ezikhethekile zenjoloba nokuthungwa kobuso besondo:

• inani elikhulu lama-lamellas;
• ukuthamba kwezinto;
• isakhiwo esinezimbotshana;
• ama-microparticles abrasive.

Wonke amathayi aphikisanayo axhunywe ngenani elikhulayo lama-sipes. I-lamella ingumugqa omncane werabha lapho ukunyathela kuhlukaniswa khona. Lokhu kuhlukaniswa kwandisa ingcindezi enamathela, ngaleyo ndlela kufinyelele ukunamathela okuthuthukisiwe. Kunezinhlobo ezilandelayo ze-lamellae:

• phambene;
• i-diagonal;
• zigzag.

Isivikeli se-Velcro sifakwe ama-lugs, njenganoma yimuphi omunye umvikeli ozihlanzayo. Umehluko usekukhuleni kwabantu okuhleliwe, okuthinta kahle imayela, okuvumela ukusetshenziswa kwenani elikhulu lama-lamellas. Kusemaphethelweni ama-sipes ukuthi amathayi abambelele phezulu, futhi ngokuhlanganiswa nokujula okukhulu kokunyathela, kwakhiwa isiqephu sokuxhumana esizinzile nesisikhulu.

Ngaphansi kwesisindo semoto, ama-lamellas ku-tread blocks ahlukene, anamathela ngokoqobo ebusweni bomgwaqo ogcwele iqhwa. Lapho usuka endaweni yokuxhumana nomgwaqo, ama-sipes ayahlangana, futhi amathayi azihlanze, asuse ama-ice chips neqhwa.

Kodwa ama-lamellas akude nesimo esibalulekile kuphela. Kungakhathaliseki ukuthi zingaki zazo ezinikezwayo, ukusebenza kahle okuphezulu kokunamathela kungaqinisekiswa kuphela ngesakhiwo se-porous senjoloba. Nguye ozomunca amanzi uma eshaya umgwaqo.

Irabha ye-Velcro iqukethe ingxube ye-cryosilane ne-silica, ngakho-ke ayigugi emazingeni okushisa aphansi, futhi inani elikhulu lama-micropores likhipha ifilimu yamanzi. Ezingeni lamangqamuzana, imbobo yesondo ngayinye isebenzisana nendawo yomgwaqo ngokuvumelana nesimiso senkomishi yokumunca, enganikezeli nje kuphela umsebenzi ophumelelayo wokudonsa, kodwa futhi nebanga elifushane lokubhuleka. Ngesikhathi esifanayo, abakhiqizi abaningi bamemezela ukungezwa kwama-microparticles aqinile wemvelaphi ye-inorganic kanye ne-organic kungxube yenjoloba. Ama-abrasives anjalo enza umsebenzi wohlobo lwama-mini-spikes, okuthuthukisa kuphela izakhiwo zokungqubuzana.

Uyini umehluko phakathi kwerabha evamile kanye ne-friction?

Lapho lingekho iqhwa neqhwa eliminyene, isisombululo esingcono kakhulu siwukusebenzisa iraba yokungqubuzana. Yilezi zimo ezinobuningi beqhwa elixegayo, iphalishi leqhwa kanye netiyela elimanzi okujwayelekile emigwaqweni yasemadolobheni ase-Ukraine ebusika. Amathayi e-Friction angasetshenziswa phakathi nenkathi lapho kusafudumele emini, futhi isithwathwa singenzeka ebusuku futhi akusakwazi ukusebenzisa amathayi ehlobo.

Lawa amathayi anenjoloba ethambile kunamathayi agxilile futhi aba tan kancane kubanda kakhulu. Ikhono labo lokuhlinzeka ngokubamba okuthembekile endaweni yomgwaqo ligcinwa emazingeni okushisa angama-25 ° C nangaphansi.

Amasondo e-Friction awanawo ama-spikes. Ngakho-ke, enye yezinzuzo zabo ngaphezulu irabha ehlanganisiwe ngokusobala - abanomsindo omncane kakhulu. Eqhweni, akukho mehluko, kodwa eqhweni noma etiyela, amathayi ashayisanayo athule ngokuphawulekayo. 

Amathayi afundiwe ngaphandle kokuncintisana ngeqhwa elihlanzekile neqhwa eligcwele phama. Ama-spikes awusizo ikakhulukazi ezindaweni ezishelelayo emazingeni okushisa aseduze nokuqhwa lapho kunongqimba lwamanzi phezu kweqhwa ukuze asebenze njengesithambiso. Amasondo e-Friction ezimweni ezinjalo awasebenzi. Ama-stud azothokozelwa ngabashayeli abangenalwazi. Kodwa ama-spikes anomsindo kakhulu, awakulungele ukushayela ngesivinini esiphezulu, anebanga elinwetshiwe lokubhuleka endaweni egandaywe ngamatshe futhi adala umonakalo omkhulu endaweni yomgwaqo. Emazweni amaningi aseYurophu, ukusetshenziswa kwawo kunqunyelwe noma kunqatshelwe ngokuphelele.

Wonke amathayi esizini aziyona neze “incazelo yegolide”, njengoba ingase ibonakale ekuqaleni, njengoba iphansi ekusebenzeni kwawo kokubili amathayi asehlobo nasebusika. Lokhu akuyona into engaphezu kokuvumelana ngomzamo wokuhlanganisa okuphambene. Abashayeli bezimoto baseYurophu basebenzisa amathayi anjalo ikakhulukazi ngenkathi engekho.

Ezimweni zase-Ukraine nomakhelwane bayo abasenyakatho, amathayi ahambisana nesimo sezulu awanandaba kangako. Ububanzi bokushisa bokusebenza okuvamile buncane kakhulu - ukusuka kuqhwa elincane ukuya ku- + 10 ° C. Ngesikhathi esifanayo, ukubamba okuthembekile nomgwaqo kungenzeka kuphela kumzila oyisicaba futhi owomile. Ukushayela eqhweni naseqhweni emathayeni anjalo kumane nje kuyingozi. Ngeke kwenzeke ukonga imali ngokuthenga isethi eyodwa yazo zonke izinkathi zonyaka, kodwa ukuphepha noma, okungenani, ukunethezeka kokushayela kuzoba sengozini.
