Aluminum kayan aiki trays: Yadda za a zabi hanyar passivation da m 3003 alloy takardar?

1. Shigowa da: Bayanan Aikace-aikace da CORE bukatun 3003 Aluminum Dionoy kayan aiki

3003 aluminum gami zanen kayan aiki trays (kayan aiki na tarko, Binciken reagent na motsa jiki, masana'antu madaidaitan kayan aikin ajiya) sune manyan kayan aiki a cikin likita, Binciken kimiyya, da manyan filayen masana'antu. Dole ne su yi tsayayya da yanayin sabis na dogon lokaci kamar “lalata sinadarai (lamba tare da disinfectants, ruwan jiki/reagents), inji gogayya (sarrafa kayan aiki), da tsaftacewa akai-akai (high-zazzabi da high-matsi haifuwa)”. A bayyane, ainihin buƙatun aikin su sun mayar da hankali kan abubuwa masu mahimmanci guda uku:

1. Babban juriya na lalata: Hana zaizayar kasa daga povidone-iodine, barasa, acidic disinfectants, da dai sauransu., don hana tsatsawar oxidative (farar tsatsa/black spots) na aluminum substrate, tabbatar da rayuwar sabis na ≥3 shekaru don 3003 Aluminum Dionoy kayan aiki;

2. Tsabta mai girma: Babu pores ko ɓacin rai a saman don guje wa mannewa na gurɓataccen abu (kwayoyin cuta, reagent sharan gona), daidai da ISO likita 10993-1 biocompatibility da ka'idodin tsabta na GLP na dakin gwaje-gwaje;

3. Matsakaicin aikin hana zamewa: Kada kayan aiki su zame cikin sauƙi lokacin da aka sanya su, yayin da tabbatar da dacewa tsaftacewa (babu tarin datti da ya haifar da wuce gona da iri).

Musamman, 3003 Al-Mn alloy (dauke 1.0%-1.5% Mn) ya zama babban kayan tushe don irin waɗannan tire (lissafin kudi ya ƙare 60%) saboda ta “matsakaici ƙarfi (Ƙarfin ƙarfi 140-160MPa, saduwa da 5-10kg load-hali da ake bukata na 3003 Aluminum Dionoy kayan aiki), mai kyau tsari (ƙimar cancantar hatimi ≥95%), da farashin sarrafawa (15%-20% ƙasa da 5052)”. Duk da haka, fim din oxide na halitta na 3003 gami (kauri 5-10nm) bakin ciki ne kuma mai kyalli, yana haifar da ƙarancin juriya na lalata; haka ma, Zaɓin da bai dace ba na ƙaƙƙarfan yanayi zai rushe daidaituwa kai tsaye tsakanin tsafta da aikin hana zamewa na 3003 Aluminum Dionoy kayan aiki.

Saboda haka, zaɓin da aka haɗa hanyoyin wucewa (gina tsayayyen fina-finai masu kariya) kuma rashin tausayi (sarrafa dubawa Properties) yana da mahimmanci don ƙayyade aikin 3003 Aluminum Dionoy kayan aiki, buƙatar madaidaicin ƙira dangane da takamaiman yanayin sabis.

2. Zaɓin Hanyar Passivation don 3003 Aluminum Dionoy kayan aiki

Don magance rashin isasshen juriya na lalata 3003 alloy ta halitta oxide fim, An ƙaddamar da fasahar wucewa - ainihin sa shine samar da a “mai yawa, fim mai ƙarfi mai ƙarfi” a saman 3003 gami ta hanyar sinadarai/hanyoyin lantarki, toshe lamba tsakanin substrate da kafofin watsa labarai masu lalata. Dangane da yanayin yanayin yanayin 3003 Aluminum Dionoy kayan aiki (e.g., yarda da muhalli na matakin likita, dakin gwaje-gwaje reagent juriya), Hanyoyin wucewa na al'ada sun kasu zuwa chromate passivation (gargajiya) kuma Passium-Kyauta (na yau da kullun na yanayin muhalli). Dole ne a zaɓi zaɓi ta hanyar kwatanta aikin fim gabaɗaya, yarda da muhalli, da aiwatar da daidaitawa.

Don samar da madaidaicin tushe don zaɓar hanyar wucewa mafi dacewa don nau'ikan nau'ikan daban-daban 3003 Aluminum Dionoy kayan aiki, An kwatanta aikin da yanayin aikace-aikacen waɗannan fasahohin na yau da kullun dalla-dalla a ƙasa:

(2) Maɓallin Maɓalli na Tsarin Tsari don wucewa (domin 3003 Aluminum Dionoy kayan aiki)

Domin passivation tsari yadda ya kamata inganta lalata juriya da kuma sabis rayuwa na 3003 Aluminum Dionoy kayan aiki, Dole ne a kiyaye mahimman abubuwan sarrafawa masu mahimmanci a duk lokacin samarwa:

1. daidaitawa kafin magani: Kafin wucewa, pretreatment mataki uku-”rage girman kai (alkaline degreaser, zafin jiki 50-60 ° C, lokaci 3-5 min) → cin abinci (nitric acid 10%-15%, zafin dakin, lokaci 1-2min, cire sikelin oxide) → wanke ruwa (deionized ruwa, pH 6.5-7.5)”-dole ne a kammala. Wannan yana tabbatar da cewa babu mai ko oxide Layer da ya rage a saman 3003 Aluminum Dionoy kayan aiki; in ba haka ba, fim din passivation yana da sauƙi ga pinholes, kwasfa, ko rashin daidaituwa.

2. Bayan-curing na fim: Dangane da nau'in passivation, buƙatun bayan warkewa sun bambanta: bayan zirconium-titanium-tushen passivation, Ana buƙatar adana zafi a 120-150 ° C na 20-30min don ƙetare haɗin gwiwa da haɓaka haɗin Zr-Ti-O a cikin fim ɗin., wanda zai iya inganta juriya na lalata 3003 aluminum gami takardar kayan aiki trays ta 30%-40%; da bambanci, Passivation na tushen phosphonate kawai yana buƙatar bushewar iska a zazzabin ɗaki, sa shi ya fi dacewa da manyan tireloli masu girma (e.g., 1200×600mm tiren aikin tiyata) waɗanda suke da wahalar zafi iri ɗaya.

3. Duban fim: Domin 3003 Aluminum alloy sheet kayan aiki trays amfani a likita yanayi (aikace-aikacen da ya fi buƙata), tsananin dubawa bayan wucewa ya zama tilas: dole ne su wuce “adhesion gwajin (Gwajin giciye ta ASTM D3359, daraja 0-1), gwajin juriya na lalata (tsaka tsaki gishiri fesa ≥400h ba tare da farin tsatsa), da gwajin ragowar ion (Cr⁶⁺, Pb²⁺, da dai sauransu. ≤10pm)” don tabbatar da bin ka'idodin aminci na likita.

3. Zabin Roughness don 3003 Aluminum Dionoy kayan aiki

Bayan wuce gona da iri, Rashin ƙarfi wani abu ne mai mahimmanci wanda ke tasiri kai tsaye ga ainihin aikin 3003 Aluminum alloy sheet kayan aiki trays -yana daidaita ba wai kawai halayen anti-slip na kayan da aka sanya akan tire ba har ma da sauƙin tsaftacewa da mannewa na fim ɗin wucewa.. Dole ne a nisantar da matsananci yanayi guda biyu don irin wannan tire, yayin da suke yin mummunar illa ga aiki:

• Santsi sosai (Ra < 0.2μm): Matsakaicin juzu'i mai tsayi tsakanin saman tire da kayan kida (e.g., bakin karfe kayan aikin tiyata) sauka a kasa 0.3, yana sa kayan aiki su zame cikin sauƙi ko da a ɗan karkata 15°; haka kuma, ƙaramin yanki na lamba tsakanin fim ɗin wucewa da ƙwanƙwasa mai santsi yana rage mannewar fim ta 30%-50%, yana haifar da bawon fim a lokacin haifuwa akai-akai.

• Tsananin wuce gona da iri (Ra > 1.6μm): Zurfin pore na saman ya wuce 5μm, ƙirƙirar ɓoyayyun wurare don gurɓatawa (e.g., ragowar jini, reagent droplets) don tara-waɗannan ragowar ba za a iya cire su gaba ɗaya ba yayin daidaitaccen tsaftacewa, ƙara yawan haɓakar ƙwayoyin cuta ta hanyar 5-8 sau; haka kuma, m kololuwa aiki a matsayin anodes a cikin lalata Kwayoyin, accelerating gida tsatsa na 3003 aluminum gami substrate da gajarta da tire ta sabis rayuwa.
