Mapuranga edunhu akadhindwa (PCBs) ndiwo magamba asina kusimba ehunyanzvi hwemazuva ano, achipa mashandiro kumidziyo yemagetsi yatinoshandisa mazuva ese. Nepo kushanda kwavo kwemukati kuri nyaya inopisa, chimwe chinhu chakasiyana chinowanzo furatirwa - ruvara rwavo. Wakambozvibvunza here kuti sei maPCB ari egirinhi muruvara? Mune ino blog, isu tichaongorora munhoroondo, tekinoroji, uye zvinoshanda zvinhu zvakakonzera kukurumbira kwegirinhi PCB.
Historical Origins:
Kuti tinzwisise kuti sei girinhi yakava ruvara rwesarudzo yePCBs, isu tinofanirwa kudzokera kumakore epakati pemakumi maviri emakore. MaPCB ekutanga aigadzirwa pachishandiswa substrate inonzi Bakelite, insulating material ine ruvara rwebrown. Nekudaro, sezvo tekinoroji yakavandudzwa, iyo indasitiri yakatendeukira kune inoshanda uye inoyevedza sarudzo.
Kuenda green:
Mumakore ekuma1960, indasitiri yezvemagetsi yakatanga kushandisa epoxy resin se substrate material nekuda kwekunakisisa kwayo magetsi ekudzivirira uye ma mechanical properties. Aya maresheni anopawo mukana wakawedzerwa - kugona kuve nemavara. Green ndiyo ruvara rwesarudzo nekuda kwekuti inokwanisika uye inowanikwa nyore kune vanogadzira. Ipa inoyevedza yekupedzisa kubata kuPCB nekuvhara matani emhangura neingi yegirinhi solder mask.
Mafungiro anoshanda:
Pamusoro pezvinhu zvenhoroondo, kufunga kunoshanda kwakakonzerawo mukurumbira wegirinhi PCBs. Ngationgororei zvikonzero zviviri zvakakosha:
1. Kusiyana uye Kupinza:
Mainjiniya emagetsi nevagadziri vanosarudza girinhi nekuti inosiyana netsvuku, iyo yechinyakare ruvara rwemasolder mask ingi. Iko kusiyanisa kusanganiswa kwezvitsvuku uye zvakasvibirira kunoita kuti zvive nyore kuziva chero zvikanganiso mukugadzira uye kuunganidza maitiro. Kuwedzera kujekesa kunoderedza zvakanyanya mukana wekukanganisa uye kunovandudza huwandu hwese hwekugadzirwa kwePCB.
2. Kuneta kwemaziso:
Chimwe chikonzero chiri kumashure kwesarudzo yegirinhi chine chekuita neanhu einjiniya. Kushanda nemidziyo yemagetsi uye maPCB kunoda maawa ekutarisa pamasekete akaomarara uye zvidiki zvikamu. Green inosarudzwa nekuti ivara rinoderedza kushushikana kwemaziso uye kuomarara, zvichibvumira hunyanzvi kushanda kwenguva yakareba pasina kusagadzikana kana kurasikirwa kwechokwadi. Iyo inozorodza mhedzisiro yegirinhi pameso inoita kuti ive yakakodzera kushandiswa kwenguva refu.
Dzimwe nzira dzemazuva ano:
Nepo maPCB akasvibira akatonga indasitiri kwemakumi emakore, zvigadzirwa zvemazuva ano zvakawedzera palette yePCB. Nhasi, unogona kuwana maPCB mumarudzi akasiyana-siyana, kubva pabhuruu uye tsvuku kusvika kune dema uye kunyange translucent. Idzi sarudzo dzinogadzirisa maapplication chaiwo, aesthetics yaunofarira, kana yakasarudzika yemhando zvinodiwa. Zvisinei, pasinei nehupamhi hwezvisarudzo zviripo, girini inoramba iine ruvara runonyanya kushandiswa nekuda kwekudhura kwayo, ruzivo uye kuvimbika.
Kuzivikanwa kwegirinhi PCBs kunogona kuverengerwa kune musanganiswa wenhoroondo, tekinoroji uye zvinoshanda zvinhu. Kubva pamidzi yaro yekutanga mukukwanisa uye kuwanda kwegirinhi epoxy, kusvika pakujeka kwayo uye kuderedzwa kwemaziso, ruvara rwave rwakafanana neindasitiri yemagetsi. Nepo musika parizvino uchipa huwandu hwakakura hwesarudzo dzemavara, zvakachengeteka kutaura kuti maPCB egirinhi acharamba achitonga kune ramangwana rinoonekwa.
