Gutezimbere Ubushyuhe-Ikidodo muri 8011 H18 Ifu ya Lacquered for Kawa Capsule Lidding                     

Mu musemburo umwe wa kawa ya capsule, ifiriti yipfundikizo ikora nk'inzitizi ya hermetic irwanya ogisijeni hamwe na membrane ikora-irekura igitutu mugihe cyo kuyikuramo. Imirongo yuzuza capsule ikora ku muvuduko mwinshi, bisaba gukora neza kugirango ubushyuhe bugere kuri zeru zidafite inenge kuri polypropilene (PP), polyethylene terephthalate ( PE T), cyangwa umubiri wa aluminium capsule.

Kugera ku bushyuhe buri gihe hamwe no gukomeza umuvuduko ukabije mugihe cyo guteka byerekana ikibazo gikomeye cyo gukora: imbaraga zidahagije zubushyuhe-kashe ziganisha kumiyoboro yameneka no kwangirika kwubuzima , mugihe gufunga kashe birenze urugero birinda urushinge rusukuye no gukuramo kimwe. Kurinda ibyo kunanirwa gupakira bisaba kuringaniza ubushyuhe bwa metallurgical, ubushyuhe bwa kashe ya lacquer uburemere, gufunga idirishya ryubushyuhe, no gukwirakwiza umuvuduko.

Inzitizi ya Hermetike Inyangamugayo vs Gukuramo Imyitwarire Iturika

Urupapuro rufunitse rwa kawa capsule rugomba kugumana igipimo cyuzuye cyo kwanduza ogisijeni (OTR) hamwe n’umuvuduko w’umwuka w’umwuka (MVTR) wa zeru kugira ngo ubungabunge ibintu bihumura neza. Mugihe cyo gukuramo, amazi ashyushye yinjizwa muri capsule, bizamura umuvuduko wimbere. Urupapuro rwa 8011 H18 rugomba kwifata kugirango rwongere kwiyongera hanyuma rugaturika kimwe kurwanya plaque ya piramide ikuramo imashini idatanyaguye kuva kuri capsule.

Micro-Kumeneka Ingaruka Kumurongo Wihuse wo Gupakira

Gukomeza kuzenguruka cyangwa kumurongo capsule yuzuza no gufunga imirongo ikora ku muvuduko wa 200 kugeza 600 capsules kumunota. Uburyo busanzwe bwo kunanirwa burimo:

Umuyoboro Usohora: Imiyoboro mito ya microscopique iterwa no kwanduza ivumbi rya kawa kuri capsule flange mugihe cyo kuzura.

Flange Delamination: Gukora lacquer idahagije cyangwa ubushyuhe budahuye bwo gutera ubushyuhe butera gukuramo impande zose.

Umwobo wa Micro-Ivunika: Fayile foil micro-cracking iterwa numuvuduko wimpfu zingana cyangwa guhindagurika kwicyuma bidahagije mugihe cyo gufunga impeta.

Ibikoresho bya tekiniki Matrix: Gupanga ibipimo by'ibikoresho

Imbonerahamwe ikurikira irerekana ibyingenzi byingenzi bya tekinike kuri 8011 H18 ya kawa ya capsule yapanze:

Ubushyuhe bwo gufunga ibipimo: Idirishya rya Triaxial

Ibibazo

Q1: Kuki 8011 H18 ikunzwe kurenza 8011 O ubushyuhe bwa kawa capsule?

Igisubizo: Ubushyuhe bwa H18 burakomeye rwose, butanga imbaraga nyinshi (≥ 165 MPa) hamwe no kuramba (≤ 3%). Ibi bituma gutobora neza ukoresheje inzoga no kugenzura guturika utarambuye cyane. O umujinya (annealed) uroroshye cyane kandi urambuye byoroshye munsi yigitutu, biganisha kunanirwa inshinge .. 

Ikibazo cya 2: Nigute uburemere bwa kashe ya lacquer ikoti igira ingaruka kumutwe wa capsule?

Igisubizo: Uburemere bwikoti budahagije (<3.5g / m²) butera kashe idakomeye (<5 N / 15mm) kandi umuyoboro uva mukungugu ka kawa. Uburemere bwikoti burenze urugero (> 7.0g / m²) byongera igiciro, byongerera igihe cyo gutura igihe cyo guturamo, kandi birashobora gutera umurongo wa lacquer kumasaya.

Q3: Niki gitera capsule flange kumeneka mugihe cyo gukuramo ikawa yumuvuduko mwinshi?

.Igisubizo

Q4: Nigute BPA-NI ubushyuhe-kashe ya lacquer ikora ugereranije na epoxy-fenolike gakondo?

Igisubizo: BPA-NI igezweho (Bisphenol A Ntabigambiriye) yahinduwe acrylic na polyolefin lacquers ihuza cyangwa irenga ibisigisigi bya epoxy-fenolike gakondo hamwe nimbaraga zumuriro, mugihe byujuje byuzuye amahame akomeye yuburayi (EU 10/2011) hamwe na FDA yo muri Amerika yo guhuza ibiryo.

Q5: Ni ubuhe buryo busanzwe bwa pinhole kuri 30 micron ya kawa ya capsule yuzuye?

Igisubizo: Ku gipimo cya 30 mkm no hejuru yacyo, fayili yo mu rwego rwo hejuru 8011 ya aluminium igomba kugera kuri zeru ya pinhole (0 pinholes / m²), itanga inzitizi yuzuye yo kurwanya ogisijeni, ubushuhe, no kwinjira mu mucyo.

Umwanzuro

Kunoza imikorere-yubushyuhe muri 8011 H18 ya kawa ya capsule yometseho ikariso isaba kuringaniza metallurgie, gukwirakwiza uburemere bwikoti, hamwe nibikoresho bya kashe. Kurinda iyi mpirimbanyi bikuraho inenge zipakirwa, birinda ikawa nshya, kandi byemeza ko abakiriya batagira inenge.

Kugirango uhindure ubuziranenge bwo gupakira kandi utekanye umusaruro muremure wokwizerwa:

Huza Substrate Mechanics hamwe nibikenerwa byo gukuramo: Kugaragaza 8011-H18 ivangwa muri 20 - 40μm zapima kugirango uhuze imbaraga zo guhangana nuduce hamwe nigitutu kimwe giturika kumasahani ya piramide.

Kunoza uburemere bwa Lacquer: Gutegeka 4.5 - 6.5 g / m² uburemere bwikoti yumye yintego ihuye na resin (PP cyangwa kwisi yose) kugirango wirinde imiyoboro yameneka no kunanirwa kwanduza.
