Me yasa kayan aikin hako PCB suka fi son sansanonin dutse na ZHHIMG®?

A fannin haƙo haƙoran PCB daidai, tushen dutse na ZHHIMG® ya zama madadin da aka fi so fiye da tushen ƙarfe saboda fa'idodinsa guda huɗu:
1. Tsarin da ke da ƙarfi: Kyakkyawan juriya ga nakasawa
An zaɓi baƙin dutse mai yawan 3100kg/m³. Lu'ulu'u na ma'adinai na ciki suna da yawa kuma matsin lamba na ciki na halitta kusan sifili ne. Idan aka kwatanta da matsalar zamewar lattice na firam ɗin ƙarfe a ƙarƙashin kaya na dogon lokaci, firam ɗin granite na iya danne sama da kashi 90% na nakasar, yana tabbatar da cewa na'urar haƙa ramin tana kiyaye daidaiton matsayi na ±1μm na dogon lokaci.
2. Ingantaccen amfani da girgiza: Daidaiton haƙa ramin ya inganta sau 3
Gogayya tsakanin ma'adanai na ciki na granite yana haifar da damshi na halitta, wanda zai iya shan kashi 90% na kuzarin girgiza yayin aikin haƙa (tushen ƙarfe na iya shan kashi 30% kawai). Ainihin ma'aunin wani masana'anta na PCB ya nuna cewa bayan shigar da tushen granite, ƙaiƙayin bangon rami mai ƙananan rami na 0.1mm ya faɗi daga Ra1.6μm zuwa Ra0.5μm, kuma an tsawaita tsawon rayuwar injin haƙa ramin da sau biyu.
Uku. Ƙarfin kwanciyar hankali na zafi: Ana rage tasirin bambancin zafin jiki
Matsakaicin faɗaɗa zafin jiki shine 5.5×10⁻⁶/℃ kawai (11.5×10⁻⁶/℃ ga ƙarfe). Lokacin da yanayin zafi na aiki na kayan aiki ya tashi da 10℃, lalacewar zafin jiki na tushen granite ya kasance ƙasa da 5μm, yayin da na tushen ƙarfe zai iya kaiwa 12μm, ta yadda zai guji daidaita matsayin ramin da faɗaɗa zafin jiki da matsewa ke haifarwa.
iv. Daidaiton Sarrafawa: An tabbatar da shi ta hanyar ma'aunin matakin nanometer
Ana sarrafa shi ta hanyar injin niƙa CNC mai ginshiƙai biyar, tare da sarrafa lanƙwasa a cikin ±0.5μm/m, kuma yana tallafawa ramukan T na musamman, ramukan zare da sauran tsare-tsare masu rikitarwa. Wani lamari daga wani masana'antar kayan haƙa rami ya nuna cewa daidaiton wurin shigar da ramin ya kai ±0.01mm, wanda ya fi na tushen injin ƙarfe 50% girma, wanda hakan ya rage lokacin aikin kayan aiki sosai.

Farashi da fa'idodin muhalli: Duk da cewa farashin farko ya fi kashi 15%, tsawon lokacin sabis ɗin ya wuce shekaru 10 (shekaru 5 kawai don firam ɗin ƙarfe), kuma ba ya buƙatar kulawa. Haɗarin carbon a cikin haƙar ma'adinai da sarrafa dutse ya yi ƙasa da kashi 40% fiye da na narkar da ƙarfe, wanda ya yi daidai da yanayin masana'antar kore.
