Izinto ezisetshenziswayo zangempela ziphinde zihlangane nezinto ezingalindelekile njengamakhemikhali noma izinto eziphilayo. Lokhu kusebenzisana kungase kungabhekwani ekuhlolweni okusheshisiwe. Ukuhlolwa okusheshisiwe, okwenzelwe ukufinyeza isikhathi sokuhlola, kungase kungabonakali imiphumela yokukhathala yesikhathi eside. Izinqubo zokuwohloka kancane kancane zibonakala kuphela ngaphansi kwezimo zemvelo ngokuhamba kwesikhathi eside. Imikhiqizo ensimini ihlangabezana nokuphathwa okuhlukahlukene, ukugcinwa, kanye namaphethini okusetshenziswa okungahlosiwe. Angikwazi ukulingisa lokhu ngokunembile ekuhlolweni kwelebhu. Lokhu kuholela ekungafani phakathi kokusebenza okubikezelwe kanye nokusebenza kwangempela.

Ukuqonda Ukumelana Nokudabuka Kwendwangu

Nginaka kakhulu ukumelana nokudabuka kwendwangu. Kuyisici esibalulekile sezindwangu. Izindinganiso ezithile ze-ASTM noma ze-ISO ziyangisiza ukuthi ngizihlole.

Isibonelo, ngisebenzisa:

• I-ASTM D2261 (Indlela Yokudabuka Kolimi): Lokhu kulinganisa amandla ajwayelekile adingekayo ukuze kuqhutshekwe nokudabuka. Kuhilela ukuhlukanisa 'izilimi' ezimbili ezisikiwe kusampula. Le ndlela isebenza ezindwangu eziningi zendwangu, okuhlanganisa izinto ezilukiwe, ezilukiwe, noma ezingalukiwe. Ngisika isampula engunxande ukuze ngiqale ukudabuka. Bese ngidonsa izinhlangothi ezimbili kuze kube yilapho kwehluleka. Idatha ibonisa amandla ezintambo, izibopho zefayibha, kanye ne-fiber interlocks. Iphinde ibonise ukumelana kwazo nokudabuka.
• I-ASTM D1424 (indlela ye-Elmendorf): Lokhu kusebenzisa idivayisi ye-pendulum ewayo. Kukala umsebenzi owenziwe (amandla) ukuze kusakazwe umngxuma ochazwe kusengaphambili endwangu.
• I-ASTM D5735Lokhu kuhlanganisa ukukalwa kwamandla okudabuka kwezindwangu ezingalukiwe ngenqubo yolimi.
• I-BS EN 1875-3:1998Lokhu kunquma amandla okudabuka kwezindwangu zerabha nezepulasitiki kusetshenziswa indlela ye-trapezoidal.

Lezi zindlela zinginika amaphuzu edatha athile. Zingisiza ukuqonda ukuthi indwangu izosebenza kanjani ngaphansi kokucindezeleka okudabukile. Ngisebenzisa lolu lwazi ukukhetha izinto ezingcono kakhulu zokusetshenziswa okuhlukahlukene.

Izindinganiso Ezijwayelekile Nokucatshangelwa Kwezinto Ezibonakalayo

Amandla Okudabuka Kuzo Zonke Izinhlobo Zezinto

Ngibone ububanzi obukhulu bamandla okudabuka kuzo zonke izinhlobo zezinto zokwakha. I-polyurethane ingafinyelela amandla okudabuka aphezulu kakhulu. Ifinyelela phezulu ngamakhilogremu angu-1,000 nge-intshi ngayinye eqondile (175.1 kN/m) isebenzisa i-ASTM D-624, Uhlobo C. Izinto ze-Elastomeric ngokuvamile zibonisa amandla okudabuka aphakathi kuka-50–100 kN/m. Ngibona nokwehluka phakathi kwezinhlobo zerabha:

Amafilimu epulasitiki nawo ayahlukahluka. I-polyethylene enamandla kakhulu (i-HDPE) ohlangothini lomshini (i-MD) inamandla okudabuka angu-120g. I-polyethylene enamandla amancane (i-LDPE) ikhombisa u-320g (i-MD).

Izici Ezithonya Amandla Okudabuka

Ngiyaqonda ukuthi izinto eziningi zithonya amandla okudabuka kwezinto. Ama-polymer anesisindo sama-molecule aphezulu abonisa ukumelana okungcono kokudabuka. Lokhu kungenxa yezibopho eziqinile kanye namaketanga amade. Ukuqondiswa kweketanga le-polymer kungandisa ukumelana kokudabuka kolunye uhlangothi. Kodwa-ke, kungase kunciphise kwezinye. Izithasiselo ezifana nama-filler zingandisa ukuqina kodwa zinciphise ukumelana nokudabuka. Zidala amaphuzu okucindezeleka. Ama-plasticizer athuthukisa ukuguquguquka kodwa anganciphisa ukumelana nokudabuka. Ukuqondiswa kwekristalu nakho kuthinta amandla okudabuka. Amafilimu anokuqondiswa kwekristalu okuthandwayo angaba namandla aphansi okudabuka. Uhlobo lwe-co-monomer lubalulekile futhi. Isibonelo, i-LLDPE ene-octene kanye ne-hexene co-monomers inamandla angcono okudabuka angaphakathi. Amandla okudabuka amandla aphezulu adingekayo ukudabuka isampula. Ngiwaveza njengamandla ngeyunithi ngayinye yobukhulu besampula.

Ukukhethwa Kwezinto Ezibalulekile Zezicelo Ezithile

Ngikhetha ngokucophelela izinto zokusetshenziswa ezithile ngokusekelwe ekumelaneni kwazo nokudabuka. Ukuze kube nokunwebeka okuphezulu kanye nokumelana nokudabuka, ngivame ukukhetha ama-Elastomeric Polyurethanes (EPU). Lawa mahle kuma-gaskets kanye nama-seal. I-Polyurethane Rubber inikeza ukumelana okukhulu nokuklwebheka nokuklwebheka. Lokhu kuyenza ifaneleke kakhulu ekusetshenzisweni kwezimboni okunzima. I-Natural Rubber (NR) inamandla aphezulu okudonseka kanye nokumelana nokudabuka. Ngiyisebenzisa ezindaweni ezibamba ukushaqeka. Emazingeni okushisa aphezulu, ngicabanga ngezinto ze-Polyimide ezifana ne-Kapton®. Zigcina ukuguquguquka futhi zimelana nokubola ekushiseni okuphezulu. Izixazululo ezisekelwe ku-Mica zinikeza ukumelana okungalingani kwezinga lokushisa. Ukwakhiwa okuhlanganisiwe kunikeza izixazululo ezifanele. Zihlanganisa izinto ezifana namafilimu e-polyimide namaphepha e-mica. Lokhu kubhekana nokuzinza kokushisa, ukuqina komshini, kanye nokumelana nokudabuka kwendwangu.

Ngithola ukumelana nokudabuka kuyisici esibalulekile ekukhetheni izinto. Kubalulekile ekusetshenzisweni okunengcindezi enamandla, izinto ezibukhali, noma izimo zokuhuzuka. Ukubeka phambili ukumelana nokudabuka kuqinisekisa ukuqina kwesikhathi eside, ukuthembeka, kanye nokuphepha. Ukuqonda ukuthi nini futhi kungani ukumelana nokudabuka kubalulekile kunika amandla izinqumo zami zobunjiniyela kanye nokuthuthukiswa komkhiqizo ezingcono.
