Ekuhloleni izinhlobo ezahlukene zamasondo e-urethane, kufanele sikhulume ngezici zawo ezihlukile kanye nezimo zokusetshenziswa. I-Polyurethane njengento esebenza kahle kakhulu. Inezakhiwo zayo zomzimba nezamakhemikhali ezinhle kakhulu. Ithatha indawo ebalulekile emkhakheni wokukhiqiza amasondo.
Okokuqala. Ake sibheke amasondo e-polyurethane (TPU). Lawa masondo anomgogodla we-polypropylene noma we-nylon. Ngobuchwepheshe bokubumba umjovo wesibili, ubuso besondo le-polyurethane le-A bakheka emaphethelweni angaphandle enhliziyo. Amasondo e-TPU awagcini nje ngokuba nezakhiwo zokuvikela phansi, ukumunca ukudlidliza, ukungamaki futhi ukungadayisi. Aphinde abe nokumelana okuhle nokugqwala. Amandla okugingqika kalula ezindaweni ezahlukahlukene. Ngaphezu kwalokho. Umbala wawo ungashintshwa ngokuya ngesidingo. Zivumelanise nezidingo zezikhathi ezahlukene. Kodwa-ke, kubalulekile ukuqaphela ukuthi endaweni eshisayo. Umthamo womthwalo wesondo le-TPU uzoncishiswa.
Isinyathelo esilandelayo ukuthulula isondo le-polyurethane (CPU) elastomer. Lawa masondo anomgogodla wensimbi noma we-aluminium njengomgogodla. Ama-polyurethane elastomer afakwa ku-thermosetting abunjwe ukusabela kwamakhemikhali. Akha ubuso besondo ngemva kokuqina emazingeni okushisa aphezulu. Amasondo e-CPU anezinzuzo ezifanayo zokuvikela phansi, ukungamaki kanye nokungadayisi. Futhi ayimelani ne-UV futhi ayimelani nokungqubuzana, okwenza ifaneleke kakhulu ekusetshenzisweni okudinga izinga eliphezulu lenduduzo yokusebenza. Kodwa-ke. Ayimelani namanzi ashisayo, umhwamuko wamanzi, njll.…Ngakho-ke kudingeka uqaphele lapho uyisebenzisa ezindaweni ezithile.
Ake sixoxe ngelinye isondo le-polyurethane elibunjiwe (i-CPU). Lawa masondo asekelwe kuma-elastomer e-thermoset polyurethane abunjwe ngamakhemikhali. Anezinzuzo ezifana nezesondo le-CPU elichazwe ngenhla, isibonelo ukuvikela phansi, ukumelana nokungqubuzana, njll. Okuphawulekayo kakhulu. Inezinga eliphansi kakhulu lokuguquguquka okuhlala njalo, ukumelana nokugoqa okuphansi. Iyakwazi ukumelana nemithwalo enamandla ngesivinini esiphezulu. Ilungele ukusetshenziswa ezimweni zesivinini esiphezulu.
Okokugcina. Ake sibheke isondo le-polyurethane (PUE) elinogwebu. Ngesakhiwo salo esiyingqayizivele se-microporous, leli sondo libonisa izakhiwo ezifana nokuxinana okuphansi, isisindo esilula kanye nokuguquguquka okulula. Liphinde libe nezakhiwo eziningi ezinhle kakhulu njengokuthwala umthwalo ophezulu, ukunwebeka okuphezulu kanye nokumelana nokugoqeka. Lezi zakhiwo zamasondo e-PUE ziwenza abe ukukhetha okuhle kwezinto zokwakha. Kungakhathaliseki ukuthi kunomsindo kanye nokumuncwa kwamandla noma ukudambisa ukudlidliza kanye nokuncibilikisa. Wonke angabonisa izinzuzo zawo ezihlukile.
Sekukonke. Amasondo e-polyurethane, ngokusebenza kwawo okuvelele kanye nezinhlobo ezahlukahlukene, asetshenziswa kabanzi emikhakheni eyahlukene. Kusukela kumasondo e-TPU avikela umhlabathi futhi amunce ukushaqeka, kuya ekumelaneni kwe-UV kanye nokungqubuzana kwesondo le-CPU. Ngaphezu kwalokho, ubukhulu obuphansi kanye nesisindo esincane sesondo le-PUE. Uhlobo ngalunye lwesondo le-polyurethane ludlala indima ebalulekile emkhakheni walo. Ukukhetha isondo le-urethane elifanele izidingo zakho. Akugcini nje ngokwandisa ukusebenza kahle. Kuphinde kunikeze isipiliyoni esikhululekile nesiphephile.
