Ubushyuhe bwo Kuringaniza Ubushyuhe Bwuzuye-Gufunga Amavuta ya Aluminiyumu

Ku ba injeniyeri bapakira, abashinzwe ubwishingizi bufite ireme, hamwe nabakoresha imashini kumurongo uhoraho-wuzuza-kashe (FFS), kugera kashe ihamye, hermetic kashe nibyingenzi mubuzima bwubuzima bwiza no kwirinda kumeneka. Mugihe kashe yumuvuduko hamwe nigihe cyo gutura bitanga ubufasha bwubukanishi, kugenzura ubushyuhe nubushakashatsi bwibanze bwo guhuza polymer hagati yubushyuhe bwa kashe ya lacquer hamwe nigikoresho cya kontineri.

Ubushuhe bwa kashe ya lacquers ni solvent- cyangwa ishingiye kumazi ya termoplastique resin yometse kuri feri ya aluminium. Iyo ikozwe ningufu zumuriro zagenzuwe, urwego rwa lacquer ruva mubintu byumye bidafite umuyaga byumye bishongeshejwe, bigakwirakwizwa muri materique ya polymer yikombe cya plastike cyangwa tray. Gushiraho neza Ubushyuhe-kashe yubushyuhe bwa aluminiyumu yometse kumurongo ushingiye kubikoresho byabugenewe byerekana imbaraga nziza zidafite amashanyarazi.

Inyabutatu yibanze yubushyuhe-bwo gufunga imbaraga

Kugera kuri zeru-inenge bisaba kuringaniza ibintu bitatu byuzuzanya bikora:

Ubwuzuzanye bwubushyuhe, Igihe cyo Gutura, hamwe nigitutu cya kashe

1. Ubushyuhe (° C): Itanga ingufu zumuriro zisabwa kugirango zirenze ubushyuhe-kashe ya lacquer yoroshya kandi itembera, bituma iminyururu ya polymer irenga inzira.

2. Igihe cyo Gutura (Amasegonda): Igihe umusego ushyushye ushyizeho umusaya. Umuvuduko wo hejuru (> 300cups / min) ugabanya inshuro zo gutura kugeza kumasegonda 0.3 - 0.5, bisaba ubushyuhe bwo mu rwasaya kugirango ukomeze igipimo cyo kohereza ubushyuhe.

3. Umuvuduko w'urwasaya (N / mm²): Guhatira ibisigazwa byashongeshejwe muri micro-grooves ya kontineri kugirango ikureho umwuka.

Igiciro Cyinshi cyo Gutandukanya Ubushyuhe: Kudashyirwaho Ikidodo Kumeneka na Gutwika-Binyuze mu Gutesha agaciro

Gukorera hanze yidirishya ryubushyuhe buganisha ku kunanirwa gufunga:

Ubushyuhe buke (<Activation Temp): Gushonga kwa polymer bituzuye bitanga imbaraga zingirakamaro zingirakamaro, biganisha kumiyoboro yamenetse, kugabanuka kwizerwa rya hot-tack, hamwe no gufunga imburagihe mugihe cyo gutambuka.

Substrate-yihariye Ubushyuhe-Ikimenyetso Parameter Matrix

Inganda zikoreshwa mu nganda & Igenamiterere ryimashini

Ubushuhe busabwa buratandukanye murwego rwo gupakira rushingiye kumuvuduko wumusaruro nibisabwa kuri bariyeri:

Ibibazo

Q1: Nigute nshobora kumenya ubushyuhe nyabwo-kashe yubushyuhe bushya bwa fayili nshya?

Igisubizo: Kora ikizamini cyo gufunga icyiciro ukoresheje kalibateri ya laboratoire yubushyuhe (urugero, Brugger cyangwa Testing Machines Inc.). Ongera ubushyuhe muri 5 ° C kwiyongera kuva kuri 160 ° C kugeza kuri 220 ° C kumuvuduko uhoraho (0.4 MPa) nigihe cyo gutura (0.8sec), hanyuma usuzume imbaraga zishishwa kuri ASTM F88 kugirango umenye ikibanza cyiza cyo gufunga.

Ikibazo cya 2: Niki gitera lacquer yubushyuhe-gufatira ku rwasaya rufunga mugihe cyo gukora?

Igisubizo: Kwizirika bibaho mugihe ubushyuhe bwurwasaya burenze urugero rwumuriro wa lacquer, bigatera kwangirika cyangwa gusohoka. Irashobora kandi guterwa no gufunga urwasaya rutemewe cyangwa uburemere butaringaniye kururubuga.

Q3: Ese lacquer yubushyuhe rusange ishobora gukora ku bushyuhe bumwe ku bikombe bya PP na PS?

: No. Igisubizo ​ ​ ​

Q4: Nigute uburemere bwa lacquer yumye-firime (g / m²) bigira ingaruka kubushyuhe bukenewe bwa kashe?

Igisubizo: Ipitingi ya lacquer yuzuye (> 6.0g / m²) isaba ingufu zumuriro mwinshi cyangwa igihe kirekire cyo gutura kugirango ugere gushonga byuzuye mubugari bwurwego ugereranije nuburemere bworoshye (3.0 - 4.0 g / m²).

Q5: Ni izihe ngaruka zamavuta yo hejuru cyangwa ivumbi hejuru yubushyuhe bwa kashe?

Igisubizo: Kwanduza hejuru yubutaka bikora nkinzitizi yikingira kandi bigabanya ingufu zubutaka, bikazamura ubushyuhe bukenewe bwa 10 ° C - 15 ° C kugirango bigerweho, mugihe intege nke zishishwa muri rusange.

Umwanzuro

Gushiraho ubushyuhe bwubushyuhe-bushingiye ku bipimo by'ubushyuhe bushingiye kuri kontineri ya polymer substrate ni ngombwa kubipfunyika ubusa, byoroshye gupakira. Muguhuza aluminiyumu-isukuye cyane hamwe na lacquer yubushyuhe, ikoreshwa kimwe, ibikorwa byo gupakira birashobora kwagura amadirishya yabyo, kugabanya igipimo cyakuweho, no gukomeza ubunyangamugayo bwa kashe.
