Kungani I-Polyurethane Rubber Ikhethwa Kwezinye Izimboni?

Isingeniso

Irabha ye-polyurethane, i-elastomer eguquguqukayo evala igebe phakathi kwenjoloba nepulasitiki, isiphenduke isisekelo ezimbonini ezihlukahlukene ngenxa yezakhiwo zayo ezingavamile. Yaziwa ngamandla ayo aphezulu, ukunwebeka, nokumelana nokuguga, irabha ye-polyurethane isetshenziswa kakhulu emikhakheni efana nezimoto, ezokwakha, nezokukhiqiza. Ikhono layo lokuzivumelanisa nezinhlelo zokusebenza ezihlukahlukene likwenza kube ukukhetha okukhethwa kukho konjiniyela nabaklami abaningi. Isibonelo, ukumelana kwayo nokuhuzuka okuphakeme, okungaba mkhulu ngokuphindwe ka-10 kunezinye izinto, kukwenze kwaba semqoka kakhulu ezindaweni ezinokucindezeleka okukhulu. Ukuze uhlole ukusetshenziswa okubanzi nezinzuzo zerabha ye-polyurethane, ungabheka imininingwane enemininingwane enikezwe ngaphansi kwesihloko. Irabha yePolyurethane.

Izakhiwo ze-polyurethane Rubber

Ukuqina Nokuqina

Esinye sezici ezivelele zerabha ye-polyurethane ukuqina kwayo okumangalisayo. Ihlinzeka ngezinhlobo eziningi zamazinga obunzima, ukusuka phansi ukuya ku-20 Shore A ukuya ngaphezulu kwama-80 Shore A, okuyenza ifaneleke ukusetshenziswa okuhlukahlukene. Lokhu kuguquguquka kobulukhuni kufinyelelwa ngokwakhiwa okuhlukile, okuvumela abakhiqizi ukuthi bavumelanise izinto nezidingo ezithile. Isibonelo, ukwakheka okuthambile kulungele ukusetshenziswa kwe-cushion, kuyilapho okuhlukile okuqinile kusetshenziswa kumarola nezigxivizo zezimboni.

Ukumelana ne-Abrasion

Irabha ye-polyurethane ihamba phambili ekumelaneni nemihuzuko, idlula izinto eziningi zendabuko. Ukumelana kwayo nokugqoka kuphakeme izikhathi ezi-5 kuya kwezingu-10 kunokwerabha yemvelo noma amanye amarabha okwenziwa. Lesi sakhiwo sikwenza kube ukukhetha okuhle kakhulu kwezinhlelo zokusebenza ezinjengamabhande okuthutha, ama-gaskets, namasondo, lapho ukungqubuzana okuqhubekayo nokuguga kungenakugwema.

Amandla Okuqina Okuphakeme

Amandla aqinile erabha ye-polyurethane angafinyelela ku-600 kgf/cm², aphakeme kakhulu kunawamanye ama-elastomer amaningi. Lawa mandla aphezulu aqinisekisa ukuthi impahla ingamelana nemithwalo esindayo nezingcindezi ngaphandle kokonakala noma ukuphuka, okuyenza ifaneleke ekufuneni izicelo zezimboni.

I-Elasticity kanye Nokuguqulwa Kwezinsalela Eziphansi

Irabha ye-polyurethane ibonisa ukunwebeka okuhle kakhulu, ngobude obuhlobene obufika ku-600%. Ngisho nangaphansi kobude obunjalo obuphezulu, ukuguqulwa kwensalela kuncane, ngokuvamile kusuka ku-2% kuya ku-4%. Lesi sakhiwo sibalulekile ezinhlelweni ezidinga ukwelula nokucindezelwa okuphindaphindiwe, njengezimpawu nama-diaphragms.

Ukumelana Kawoyela Namakhemikhali

Enye inzuzo ephawulekayo yenjoloba ye-polyurethane ukumelana kwayo okuphakeme nowoyela namakhemikhali. Idlula irabha ye-nitrile ekumelaneni namafutha amaminerali futhi isebenza izikhathi ezi-5 kuya kweziyisi-6 kunerabha yemvelo. Lokhu kuyenza ibe into ekhethwayo ukuthi isetshenziswe ezindaweni ezichayeke kuwoyela, izinto zokubasa, namanye amakhemikhali anokhahlo.

Izicelo ze-Polyurethane Rubber

Imboni Yezimoto

Emkhakheni wezimoto, irabha ye-polyurethane isetshenziswa kabanzi ukukhiqiza ama-suspension bushings, ama-seal, nama-gaskets. Umthamo wayo ophezulu wokuthwala umthwalo kanye nokumelana nokugqoka kwenza kube kuhle kulezi zinhlelo zokusebenza. Ukwengeza, ikhono layo lokumelana namazinga okushisa aphakeme liqinisekisa ukusebenza okuthembekile kuzo zombili izimo ezishisayo nezibandayo.

Ezokwakha kanye Nengqalasizinda

Irabha ye-polyurethane isetshenziswa kakhulu ekwakheni izinhlelo zokusebenza ezinjengama-vibration dampers, flooring, kanye nama-coatings. Ukuqina kwayo nokumelana nokuhuzuka namakhemikhali kuyenza ibe ukukhetha okuthembekile ezindaweni zokwakha ezinokhahlo. Ngaphezu kwalokho, ukuguquguquka kwayo kuyivumela ukuthi ibambe ukushaqeka nokudlidliza ngempumelelo, ithuthukise impilo ende yezakhiwo.

Izicelo Zokukhiqiza Nezimboni

Ekukhiqizeni, irabha ye-polyurethane isetshenziswa kumabhande okuthutha, ama-roller, nezingxenye zomshini. Amandla ayo aphezulu nokumelana nokugqoka kuqinisekisa ukuthi lezi zingxenye zingakwazi ukuphatha imithwalo esindayo nokusebenza okuqhubekayo ngaphandle kokushintshwa njalo. Lokhu akunciphisi nje kuphela isikhathi sokuphumula kodwa kwehlisa nezindleko zokunakekela.

Izimpahla Zabathengi

Irabha ye-polyurethane iyatholakala nasezimpahleni ezahlukahlukene zabathengi, kufaka phakathi izicathulo, izinto zezemidlalo, nezinto zasendlini. Imvelo yayo engasindi, kuhlanganiswe nokuqina kwayo nokuguquguquka, ikwenza kube ukukhetha okudumile kulezi zinhlelo zokusebenza. Isibonelo, isetshenziswa ematheni ezicathulo zezemidlalo ezisezingeni eliphezulu ukuze kuhlinzekwe i-cushioning nokusekelwa.

Isiphetho

Irabha ye-polyurethane igqama njengezinto eziguquguqukayo nezithembekile ezihlangabezana nezidingo zezimboni ezahlukahlukene. Inhlanganisela yayo eyingqayizivele yezakhiwo, okuhlanganisa amandla aphezulu, ukunwebeka, nokumelana nokugqokwa namakhemikhali, kuyenza ibe ukukhetha okuthandwayo kwezicelo ezisukela kwezezimoto kuya kwezimpahla zabathengi. Ukuze uthole ukuqonda okujulile kwezinhlelo zokusebenza nezinzuzo zayo, ungahlola kabanzi mayelana Irabha yePolyurethane.
