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 ningirakamaro mubuzima bwubuzima bwiza no kwirinda kumeneka. Mugihe kashe ya kashe 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 yoroheje kandi itembera, bituma iminyururu ya polymer irenga inzira.

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

Gushyushya munsi (<Activation Temp): Gushonga kwa polymer bituzuye bitanga imbaraga zingirakamaro zingirakamaro, biganisha kumiyoboro yamenetse, kugabanya kwizerwa rya hot-tack, no gupfundika imburagihe mugihe cyo gutambuka.

Ubushyuhe bukabije (> Umupaka wo hejuru): Kwangirika kwubushyuhe bikurura lacquer, bigatera resin gusohoka, guhinduka ibara hejuru, gutobora ifu / gutemagura mugihe cyo gufungura, no kwanduza urwasaya rukabije.

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 cya kashe ikoresheje kalibateri ya laboratoire yubushyuhe (urugero, Brugger cyangwa Testing Machines Inc.). Ongera ubushyuhe muri 5 ° C kwiyongera kuva 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 mububyimba ugereranije nuburemere bworoshye (3.0 - 4.0 g / m²).

Q5: Ni izihe ngaruka z'amavuta yo hejuru cyangwa umukungugu ku idirishya ry'ubushyuhe bwa kashe?

Igisubizo: Kwandura hejuru yubutaka bikora nkinzitizi yikingira kandi bigabanya ingufu zubutaka, bikazamura ubushyuhe bukenewe bwa kashe ya 10 ° C - 15 ° C kugirango bigerweho, mugihe bigabanya imbaraga rusange yibishishwa.

Umwanzuro

Gushiraho ubushyuhe bwubushyuhe-bushingiye ku bipimo bishingiye kuri kontineri polymer substrate ni ngombwa kubikoresho bitarimo kumeneka, byoroshye-gupakira. Muguhuza aluminiyumu-isukuye cyane hamwe na lacquers yubushyuhe-bushyizwe hamwe, ibikorwa byo gupakira birashobora kwagura amadirishya yabyo, kugabanya igipimo cyakuweho, no kugumana ubunyangamugayo bwa kashe.
