Amakuru - Ibisubizo ku bibazo bisanzwe byo guhindagurika no kuzamura ihumure, ubwiza no kuramba mu gishushanyo mbonera cyoroshye

Iterambere: Guhindura TPE

TPE, cyangwa elastomeri ya thermoplastic, ni ibikoresho bifite uburyo bwinshi buhuza uburimbane bwa rubber n'ubudahangarwa bwa pulasitiki. Ishobora gucukurwa cyangwa gukurwamo mu buryo butaziguye, hamwe na TPE-S (elastomeri ya thermoplastic ishingiye kuri styrene) ikoreshwa cyane, ikubiyemo elastomeri za SEBS cyangwa SBS mu gukora pulasitiki za thermoplastic. TPE-S ikunze kwitwa TPE cyangwa TPR mu nganda za elastomeri.

Ariko, TPE overmolding, izwi kandi nka thermoplastic elastomer overmolding, ni inzira yo gukora ikubiyemo gushushanya ibikoresho bya thermoplastic elastomer (TPE) hejuru y'ibikoresho by'ibanze cyangwa ibintu by'ibanze. Iyi nzira ikoreshwa mu guhuza imiterere ya TPE, nko koroha no koroha kwayo, n'imiterere yihariye y'ibikoresho by'ibanze, bishobora kuba pulasitiki ikomeye, icyuma, cyangwa ikindi kintu.

Guhindura TPE bigabanyijemo amoko abiri, rimwe ni uguhindura imiterere nyayo n'irindi ni uguhindura imiterere y'impimbano. Ibicuruzwa bya TPE muri rusange ni bimwe mu bikoresho byo gufata no gufata, bitewe n'uburyo bwihariye bworoshye bwo gukoraho ibikoresho bya TPE, gushyiramo ibikoresho bya TPE byongera ubushobozi bwo gufata no kumva uko bikozwe. Ikintu kiranga ni uburyo ibikoresho bihindura imiterere y'impimbano bikoreshwa, muri rusange hakoreshejwe uburyo bwo gushushanya bw'amabara abiri cyangwa uburyo bwo gushushanya bw'inyongera kugira ngo bitwikire plastiki ni uguhindura imiterere nyayo, mu gihe ifoto ifata icyuma n'imyenda ari uguhindura imiterere y'impimbano, mu rwego rwo guhindura imiterere nyayo, ibikoresho bya TPE bishobora guhuzwa na pulasitiki zimwe na zimwe zikoreshwa muri rusange, nka PP, PC, PA, ABS n'ibindi, bifite uburyo bwinshi bwo kubikoresha.

Ibyiza by'ibikoresho bya TPE

1. Imiterere yo Kudanyerera: TPE itanga ubuso busanzwe budanyerera, yongera imikorere yo gufata ibintu bitandukanye nk'udupira twa golf, udupira tw'ibikoresho, udupira tw'uburoso bw'amenyo, na TPE hejuru y'ibikoresho bya siporo byabumbwe.
2. Ubworoherane n'Ihumure: Imiterere yoroshye ya TPE, iyo ikoreshejwe nk'urwego rwo hanze ku bikoresho bikomeye bya rubber, ituma yumva yoroshye kandi adafata.
3. Uburemere bw'Ubukomere: Kubera ko uburemere bw'ubukomere busanzwe buri hagati ya 25A-90A, TPE itanga ubushobozi bwo koroshya imiterere, bigatuma habaho impinduka mu bijyanye no kudasaza, uburemere, n'ibindi byinshi.
4. Ubudahangarwa Budasanzwe bwo Kurwanya Gusaza: TPE igaragaza ubudahangarwa bukomeye bwo kurwanya gusaza, bigatuma ibicuruzwa biramba.
5. Guhindura ibara: TPE yemerera guhindura ibara binyuze mu kongeramo ifu y'amabara cyangwa masterbatch y'amabara ku buryo bw'ibikoresho.
6. Kumenya Ihungabana n'Imiterere yaryo Idapfa: TPE ifite ubushobozi bwo gufata ihungabana no kwirinda amazi, bigatuma ikoreshwa mu gufata ahantu hifuzwa kandi igakora nk'ibikoresho bifunga.

Impamvu zitera TPE idafite umutekano ihindagurika

1. Ingorane zo gusesengura imashini zikoreshwa mu gushushanya: pulasitiki zikoreshwa cyane ni ABS, PP, PC, PA, PS, POM, nibindi. Buri bwoko bwa pulasitiki, muri rusange bufite urwego rujyanye na TPE yo gushushanya. Mu buryo bunyuranye, PP ni yo ipfunyika neza; PS, ABS, PC, PC + ABS, PE yo gushushanya pulasitiki, ariko ikoranabuhanga ryo gushushanya pulasitiki naryo rirakuze cyane, kugira ngo rigere ku imashini ikomeye yo gushushanya pulasitiki nta ngorane; imbogamizi zo gushushanya pulasitiki ya nylon PA zizaba nyinshi, ariko mu myaka ya vuba aha ikoranabuhanga ryateye imbere cyane.

2. Ubwoko bw'ingenzi bwa TPE yo gukomeretsa pulasitiki: Ubukana bwa PP yo gukomeretsa ni 10-95A; PC, ABS yo gukomeretsa iri hagati ya 30-90A; PS yo gukomeretsa iri hagati ya 20-95A; nylon yo gukomeretsa iri hagati ya PA ni 40-80A; POM yo gukomeretsa iri hagati ya 50-80A.

Imbogamizi n'ibisubizo mu bijyanye no gukoresha TPE mu buryo burenze urugero

1. Gushyiramo ibice no gukurura: Kunoza uburinganire bwa TPE, hindura umuvuduko w'ishyirwamo n'umuvuduko w'igipimo, kandi urusheho kunoza ingano y'irembo.

2. Gukuraho nabi: Hindura ibikoresho bya TPE cyangwa ushyiremo ibinyampeke by'ibihumyo kugira ngo bitagaragara cyane.

3. Gutunganya no gufatana: Gucunga ingano y'inyongera kugira ngo ukemure imyuka mito y'inyongeramusaruro.

4. Guhindura ibice bya pulasitiki ikomeye: Hindura ubushyuhe bw'inyongera, umuvuduko, n'igitutu, cyangwa ushimangire imiterere y'ibumba.

Ahazaza: Igisubizo cya Si-TPV ku bibazo bisanzwe mu gukurura ubwiza burambye

Ni ngombwa kumenya ko ahazaza ho gukoresha ibikoresho bikozwe mu buryo bworoshye (overmolding) hari iterambere rijyanye neza n'ibikoresho byoroshye!

Iyi elastomer nshya ishingiye kuri thermoplastic silicone izafasha mu gutunganya ibintu mu nganda mu buryo bworoshye kandi bunogeye ijisho.

SILIKE itanga igisubizo cy’ingirakamaro, elastomer zishingiye kuri thermoplastic silicone (mu magambo make ya Si-TPV), zirenga imipaka gakondo. Iki gikoresho gihuza imiterere ikomeye ya elastomer za thermoplastic n’imiterere ya silicone ikundwa, itanga gukoraho koroshye, kumva nk’ubudodo, no kudahura n’urumuri rwa UV n’imiti. Elastomer za Si-TPV zigaragaza gufatana ku buryo budasanzwe ku bintu bitandukanye, zigakomeza gutunganya neza nk’ibikoresho bisanzwe bya TPE. Zikuraho ibikorwa bya kabiri, bigatuma habaho ingendo zihuse kandi zigabanye ikiguzi. Si-TPV itanga imiterere isa n’iya silicone ku bice byakozweho cyane. Uretse imiterere yayo itangaje, Si-TPV yemera kuramba kuko ishobora kongera gukoreshwa no gukoreshwa mu buryo busanzwe. Ibi byongera ibidukikije kandi bikagira uruhare mu mikorere irambye.

Elastomer za Si-TPV zidafite pulasitiki zikwiriye ibikoresho bihuza uruhu, zitanga ibisubizo mu nganda zitandukanye. Ku bijyanye no gushushanya ibikoresho bya siporo, ibikoresho, n'imifatabuguzi itandukanye, Si-TPV yongera "ibyiyumvo" byiza ku gicuruzwa cyawe, iteza imbere udushya mu gushushanya no guhuza umutekano, ubwiza, imikorere, na ergonomics mugihe ikurikiza imikorere idahungabanya ibidukikije.

Ibyiza byo gukoresha Soft Overmolding hamwe na Si-TPV

1. Gufata no gukorakora neza: Si-TPV itanga uburyo bwo gukorakora neza kandi bunogeye uruhu igihe kirekire nta ntambwe z'inyongera. Yongera cyane uburyo bwo gufata no gukorakora, cyane cyane mu mifuka no mu mifuka.

2. Ihumure ryinshi n'ibyiza: Si-TPV itanga ihumure ridahindagurika rirwanya umwanda, rigabanya ivumbi ryinshi, kandi rikuraho gukenera pulasitiki n'amavuta yoroshya. Ntirigwa kandi ntirigira impumuro mbi.

3. Kuramba neza: Si-TPV yongera imbaraga zo gushwanyagurika no kudashwanyagurika, bigatuma ibara riramba, ndetse no mu gihe cy'ibyuya, amavuta, urumuri rwa UV, n'imiti. Igumana ubwiza, bigatuma ibicuruzwa biramba.

4. Ibisubizo byo Guhindura Ibyuma mu buryo butandukanye: Si-TPV yifata ubwayo kuri pulasitiki ikomeye, bigatuma habaho uburyo bwihariye bwo guhindura ibyuma mu buryo budasanzwe. Ifatana byoroshye na PC, ABS, PC/ABS, TPU, PA6, n'ibindi bisa na byo bidakeneye kole, bigaragaza ubushobozi budasanzwe bwo guhindura ibyuma mu buryo budasanzwe.

Mu gihe tubona iterambere ry'ibikoresho bihindura ibintu, Si-TPV igaragara nk'imbaraga zihindura ibintu. Ubwiza bwayo butagereranywa bwo gukoraho ibintu byoroshye no kurambye bituma iba ibikoresho by'ejo hazaza. Suzuma ibishoboka byose, vugurura imiterere yawe, kandi ushyireho amahame mashya mu nzego zitandukanye ukoresheje Si-TPV. Emera impinduramatwara mu gukoraho ibintu byoroshye - ejo hazaza ni ubu!
