Uzi byinshi ku nsinga za polyurethane? (Insinga za TPU)

Insinga ya Polyurethanes bivuga insinga zikoresha ibikoresho bya polyurethane nk'ubushyuhe cyangwa icyuma. Ubushyuhe bwazo bukabije bwo kwangirika busobanura ubushyuhe bukabije bw'icyuma gikingira n'urwego rwo gukingira.

 

Ibikoresho bya polyurethane bikoreshwa mu nsinga muri rusange byitwa TPU, ari byo rubber ya polyurethane elastomer ya thermoplastic. Bigabanyijemo ubwoko bwa polyester n'ubwoko bwa polyether, bifite uburebure bw'ubukana (60HA-85HD), birwanya kwangirika, birwanya amavuta, bibonerana kandi birambara neza. TPU ntabwo ifite gusa imiterere myiza yo kwangirika, gushyuha cyane, gushyuha cyane, gukomera no gusaza, ahubwo inagira akamaro ko kwirinda ibidukikije.

 

Uyu munsi, Lansheng Cable izakugeza ku bintu 8 by'ingenzi n'ibice 8 by'ingenzi bya polyurethane cable.

 

Ibintu 8 by'ingenzi:

1. Ubudahangarwa ku kwambara imyenda

 

Iyo insinga ikunze gukoreshwa mu buryo bwa mekanike nko gukururana, gushwanyaguza no gusya mu gihe cyo kuyikoresha, bizatuma ubuso bwayo bugenda busaza buhoro buhoro, bityo uburyo bwo guhitamo ibikoresho ni ingenzi cyane.

 

Ibikoresho fatizo bya pulasitiki bya TPU bifite ubushobozi bwo kwangirika neza kandi bikubye inshuro zirenga eshanu insinga zisanzwe zifite igitambaro cya rubber. Ni kimwe mu bikoresho bya mbere bikoreshwa mu gukora ibikoresho bidashobora kwangirika.

 

2. Imikorere ya Tensile

 

Ingufu zo gukurura imigozi ya polyurethane zigera kuri 38MPa, naho imbaraga zo gukurura imigozi isanzwe yo mu ntoki (imwe mu nsinga zikunze kuboneka ku isoko) ni 8-12MPa gusa.

 

Iyo insinga ikoreshejwe ahantu hakoreshwa imbaraga nyinshi, insinga ifite agapira gafite ingufu nke zo gukurura, kandi igice cyo hagati cy’insinga gihita gicika byoroshye nyuma yo gukururwa n’inyuma. Kuba insinga za polyurethane zirinda cyane gukurura no gukingira bigira uruhare rwiza mu kurinda igice cyo hagati cy’insinga, bigatuma kiramba kandi kiramba.

 

3. Imikorere y'amarira

 

Imbaraga z'amarira ni ubushobozi bw'ibikoresho bwo kwihanganira amarira. Muri rusange, TPU ifite ubushobozi bwo kurwanya amarira menshi, kandi imbaraga z'amarira ni nziza cyane ugereranyije na za kabutike na pulasitiki bikunze gukoreshwa.

 

4. Imikorere yo kuzunguruka

 

Insinga nyinshi za pulasitiki (nka RVV) zikunze kuvunika iyo zikomeje gukaza umuvuduko ukabije. Insinga za poliyuretani zishobora kugumana imbaraga zo gukomera neza mu bidukikije bitandukanye, bigatuma ziba zimwe mu mahitamo meza yo gukomera mu bidukikije bihoraho.

 

5. Ubudahangarwa bwa hydrolysis

 

Insinga za polyurethane zifite ubushobozi bwo kurwanya amazi neza iyo zimeze nk'izifite umukungugu, kandi ntizishobora kugira ikibazo cyo gushonga amazi mu gihe cy'umwaka umwe cyangwa ibiri, cyane cyane ko uruhererekane rwa polyether ari rwo rwiza kurushaho.

 

6. Kurwanya ubushyuhe bwinshi no kurwanya ogisijeni

 

Muri rusange, ibikoresho fatizo bya pulasitiki byoroshye gukaraba ahantu hari ubushyuhe buri hejuru ya 70°C igihe kirekire, kandi TPU ifite ubushobozi bwiza bwo kurwanya antioxydant; muri rusange, ubushyuhe bwa TPU bushobora kugera kuri 120°C.

 

7. Ubudahangarwa bw'amavuta n'imiti

 

TPU ni ibikoresho bya polimeri bifite imiterere isanzwe cyane, bifitanye isano ridakomeye n'amavuta y'ubutare atari imiterere isanzwe kandi ntibishobora kwangirika mu mavuta ya lisansi (nka peteroli, lisansi) n'amavuta ya mekanike (nka hydraulic oil, moteri oil, amavuta yo kwisiga, nibindi); muri byo, ibikoresho bya polyester ni byiza mu nsinga za polyurethane.

 

8. Imikorere y'ubushyuhe buri hasi

 

Insinga za polyurethane zifite ubushyuhe buri hasi kandi akenshi zigera kuri -50°C. Zishobora gusimbura imirima itandukanye aho insinga rusange za PVC n'iz'amaboko ya rubber zidashobora gukoreshwa bitewe n'ubushyuhe buke. Zikwiriye cyane cyane insinga zikoreshwa ahantu hakonje cyane.

 

 

Ahantu ho gukorerwamo porogaramu:

 

01Insinga yo gukoresha mu mazi

 

Ubwoko bw'insinga zo munsi y'amazi bushobora kugabanywamo ibice bine gusa.

 

Mu buryo bw'imiterere, igabanyijemo cyane cyane insinga zo mu mazi zifite imiterere itatu n'insinga zo mu mazi zifite imiterere imwe. Insinga ziciriritse n'iziciriritse zikoresha insinga zo mu mazi zifite imiterere itatu, naho insinga zikoresha amashanyarazi menshi zikoresha insinga zo mu mazi zifite imiterere imwe; mu buryo bw'imikorere, mu myaka mirongo itanu ishize, insinga zo mu mazi zari zifite imikorere yoroshye yo kohereza ingufu. Ubu insinga zo mu mazi zihuza imirimo ibiri, bigatuma amashanyarazi n'ibimenyetso bikwirakwira ku murongo umwe w'insinga; mu buryo bw'imiterere y'ubushyuhe, zigabanyijemo insinga zo mu mazi zishyushye zuzuye amavuta n'insinga zo mu mazi zishyushye za pulasitiki; mu buryo bw'ubwoko bw'umutwaro, zigabanyijemo insinga zo mu mazi zishyushye za DC n'insinga zo mu mazi zishyushye za AC. Ibiranga insinga zo mu mazi zishyushye za DC ni igihombo gito kandi byoroshye kugeraho mu kohereza intera ndende, ariko ubunararibonye bw'insinga zo mu mazi zishyushye za DC ntabwo bukungahaye. Ibiciro byo kubaka sitasiyo za DC converter ni byinshi, kandi insinga zo mu mazi zishyushye za AC ni nini, ariko ikoranabuhanga ryo gukoresha no kubungabunga rimaze igihe kandi ikiguzi cyo kubaka ni gito. Kubwibyo, abashushanya insinga zo mu mazi bakunze gukora ubucuruzi bwa tekiniki n'ubukungu kugira ngo babone inyungu nyinshi.

02  Roboti zo mu nganda na Insinga ya Robotics

 

Birumvikana ko robo zirenga kimwe cya kabiri cy’inganda nshya ku isi zashyizweho mu Bushinwa, kandi robo zikorerwa mu Bushinwa nazo zifite uruhare runini. Kubera ko ari ibice bihuye na robo, icyifuzo cyo guteza imbere insinga za robo ntigikwiye gusuzugurwa. Inganda z’inganda za robo zirimo gutera imbere mu Bushinwa kandi zirimo gukurura abantu benshi bashishikajwe n’ibigo by’insinga. Nk’igice cy’ingenzi cya robo, Insinga n'Insinga byagaragaje ukwiyongera gukomeye mu gukenera isoko, kandi amasosiyete y’insinga n’imiyoboro y’amashanyarazi azazana amahirwe adasanzwe yo guteza imbere no guhindura ibintu.

03 Imashini zo ku cyambu n'insinga ya gantry crane reel

 

Insinga ya gantry crane reel igomba kuba ishobora gupfunyika insinga mu buryo bwikora, kandi imbaraga zitwara insinga ntizigomba kuba munsi y’imbaraga ntarengwa zisabwa mu gihe cyo gupfunyika insinga. Mu gihe cyo kurekura insinga, imbaraga zitwara zikora ku muyobora insinga zigomba kuba ntoya uko bishoboka kose. Ku nsinga zidafite igice cy’imbere gikomejwe, imbaraga ntarengwa zishoboka zikoreshwa ku gice cy’umuyobora w’umuringa ni 20N/mm². Ku muvuduko ukenewe wo gupfunyika insinga cyangwa uburemere bw’insinga bukabije, umugozi w’icyuma ukomejwe ushobora kwihanganira imbaraga zisabwa zo gupfunyika ugomba kongerwaho nk’igice cy’imbere.

04Insinga z'imashini z'ubucukuzi bw'amabuye y'agaciro

 

Insinga n'insinga z'imashini zikora ubucukuzi bw'amabuye y'agaciro bisaba ubushobozi bwo kwangirika neza, kudakoresha hydrolysis, kudakoresha ubushyuhe bwinshi no kudakoresha oxidation, bityo ibisabwa ku bikoresho by'insinga n'insinga nabyo birakomeye cyane.
