Mubasa rekugadzira zvinhu zvemagetsi, kururama kwekugadzirwa kwemabhodhi emagetsi akadhindwa (PCBS) kwakabatana zvakananga nekushanda uye mhando yezvigadzirwa zvemagetsi. Semidziyo mikuru mukuita kwekuchera, kugadzikana kwekushanda uye kururama kwekugadzirisa michina yekuchera yePCB kwakakosha zvikuru. Pakati pavo, chinhu chinowanzo furatirwa asi chakakosha zvikuru - granite base - ndechekuona kana kugona kwemidziyo kuchigona kuwedzerwa.
Zvakanakira zvegranite bases
Kugadzikana kwakanyanya, kunodzivirira kukanganiswa kwekudengenyeka
Munguva yekuboorwa kwePCB, chidhiraivho chinotenderera nekumhanya kukuru kuti chicheke bhodhi, zvichigadzira kudedera kunoenderera mberi uye kwakaoma. Hwaro hwegranite, hune chimiro chayo chakakora uye chakafanana chakagadzirwa nemaitiro e geological kwemazana emamiriyoni emakore, hune simba rakasimba kwazvo rekudengenyeka kwenyika. Granite yepamusoro inomiririrwa ne "Jinan Green" yakaoma muchimiro uye inogona kunyudza uye kuparadzira simba rekudedera rinogadzirwa nekushanda kwemidziyo, ichivimbisa kugadzikana kwemidziyo yekuboorwa panguva yekushanda. Kana ichienzaniswa nedzimwe nheyo dzezvinhu, granite inogona kuderedza zvakanyanya kukanganiswa kwekudedera pakurongeka kwenzvimbo yekuboorwa, zvichiita kuti kururama kwenzvimbo yemakomba akaboorwa kuve kwakakwirira uye kutsauka kunodzorwa mukati menzvimbo diki kwazvo, zvichisangana nezvinodiwa zvekuboorwa zvakanyatsonaka zvemakomba madiki uye dhayamita diki yemabhodhi ePCB ane density yakakura.
Kuomarara kwakanyanya uye kuramba kupfeka zvinovimbisa kurongeka kwenguva refu
Kuboorwa kakawanda kunopa dambudziko guru pakudzivirira kupfeka kwepasi. Kuomarara kwegranite kweMohs kunogona kusvika 6 kusvika ku7, kupfuura kure kwesimbi dzakajairika nemapurasitiki mazhinji einjiniya. Hunhu uhwu hwekuomarara kwakanyanya hunoita kuti pasi regranite rirambe rakatsetseka uye rakatsetseka pamusoro paro kunyangwe parinobatwa nesimba rekukanda uye kukweshana kwechikamu chekuboorwa kwenguva yakareba. Kunyangwe mushure memabasa akawanda ekuboorwa, mwero wekuora haunyanyi kukosha, nokudaro zvichiita kuti michina yekuboorwa ishande zvakanaka kwenguva refu uye kururama kwekuboorwa kugare kuripo. Izvi zvakakosha zvikuru kumabhizinesi makuru ekugadzira PCB. Zvinogona kuderedza nguva yekushanda kwemidziyo uye nguva yekugadzirisa inokonzerwa nekumboorwa kwepasi, kuvandudza kushanda zvakanaka kwekugadzira uye kudzikisa mutengo wekugadzira.
Kukura kwekupisa kwakaderera uye kudzikira, kunoenderana nekuchinja kwekupisa
Munzvimbo yekugadzira maPCB, tembiricha yemamiriro ekunze inochinja-chinja nekuda kwezvinhu zvakaita semwaka uye kupisa kwemidziyo. Hwaro hwakagadzirwa nezvinhu zvakajairika hune kuwedzera kwekupisa uye kusimba kwezvikamu, izvo zvinokonzeresa shanduko munzvimbo dzezvikamu zvemidziyo uye nekudaro zvichikanganisa kurongeka kwekuboorwa. Granite ine chiyero chakaderera kwazvo chekuwedzera kwekupisa. Semuenzaniso, chiyero chekuwedzera chakaenzana chegranite yakajairika chingangoita 4.6×10⁻⁶/℃. Kana tembiricha ikachinja, saizi yehwaro hwegranite inoramba yakafanana, zvichipa hwaro hwakasimba uye hwakavimbika hwemidziyo yekuboorwa. Ingave muzhizha rinopisa kana munguva yechando inotonhora, michina inogona kuchengetedza mamiriro ekuboorwa akanyatsojeka, ichivimbisa kuenderana kwemhando yekuboorwa kwezvigadzirwa zvePCB zvakasiyana.
Gadzirisa mashandiro emidziyo yekuboora yePCB
Kuisa nekuronga nemazvo ndiko kunoita kuti pave negwara rekuita kuti zvinhu zvive zvakarurama
Munguva yekugadzirisa hwaro hwegranite, kuburikidza nehunyanzvi hwekucheka nekukuya kwedhaimani, kutwasuka kwakanyanya uye kurongeka kwehukuru kunogona kuwanikwa. Semuenzaniso, kushivirira kutwasuka kwehwaro hwegranite hwakanyatsonaka mukati me1m×1m kunogona kudzorwa kusvika pa4μm. Izvi zvinoita kuti michina yekuboorera iiswe nekukurumidza uye nemazvo zvichibva pane plane chaiyo uye chimiro chekuisa hwaro, nekusiyana kushoma kwechikamu chimwe nechimwe. Kuisa nekuiswa kwakanyatsonaka kunopa vimbiso yekufamba kwakarurama kwechidimbu chekuboorera panguva yekushanda kwemuchina, zvichivandudza kururama kwekuboorera kubva panobva uye zvinobudirira kuderedza matambudziko akadai sekutsauka kwenzvimbo yemaburi uye dhayamita yemaburi isingaenderane nekuda kwekuisa michina zvisina kunaka.
Kuvandudza kusimba kwechimiro uye kuvandudza kugadzikana kwekushanda
Kana michina yekuboora PCB ichishanda, pamusoro pekudedera kwayo, inogonawo kukanganiswa nekutakura kwekunze, pasi reworkshop risina kuenzana nezvimwe zvinhu. Hwaro hwegranite hune kusimba kwakanyanya uye hwakasimba. Mushure mekunge hwabatanidzwa zvakanyanya nechimiro chikuru chemidziyo, hunogona kuwedzera kusimba kwechimiro chemidziyo yese. Kana michina ikakanganiswa nechisimba chekunze kana kudedera, hwaro hwegranite hunogona kuparadzira simba rekurovera zvakaenzana nekusimba kwaro kwakasimba, zvichidzivirira zvikamu zvakakosha zvemidziyo kuti zvisabve panzvimbo kana kuremara nekuda kwesimba risina kuenzana, uye kuve nechokwadi chekushanda kwakasimba kwemidziyo mumamiriro ekushanda akaomarara. Mamiriro ekushanda akagadzikana anobatsira kuwedzera hupenyu hwebasa remidziyo uye anopa nzvimbo yakagadzikana uye yakavimbika yekushanda yekuboora kwepamusoro panguva imwe chete.
Mhedzisiro chaiyo yekushandisa kugadzirwa
Kugadzirwa kwePCB yezvigadzirwa zvemagetsi zvevatengi
Mukugadzirwa kwePCBS yezvigadzirwa zvemagetsi zvevatengi zvakaita semafoni madiki nemapiritsi, zvinodiwa kuti kuchera kuve kwakarurama zvakanyanya. Mushure mekunge kambani inozivikanwa yekugadzira macomputer yatanga michina yekuchera maPCB ine magranite bases, goho rezvigadzirwa rakawedzera kubva pa80% yekutanga kusvika pamusoro pe90%. Matambudziko akadai sekubatana kwetambo dzisina kunaka uye short circuit zvinokonzerwa nekusakwana kwekugadzirisa macomputer zvakaderedzwa zvakanyanya. Panguva iyi, nekuda kwekudzikisa nguva yekugadzirisa macomputer, kugona kwekugadzira kwemwedzi wega wega kwekambani iyi kwakawedzera ne20%, zvichideredza mutengo wekugadzira pachinhu chimwe nechimwe uye zvichiwana mukana wemutengo nerunako mumakwikwi emusika.
Kugadzirwa kwebhodhi rekudzora maindasitiri rePCBS
Nzvimbo yekushanda yemabhodhi ekudzora maindasitiri yakaoma, uye zvinodiwa zvePCBs zvakasimba. Kambani inonyanya kugadzira mabhodhi ekudzora maindasitiri yakaona kuwedzera kukuru kwekupasa kwemabhodhi ayo ePCB mumiedzo yakaoma yezvakatipoteredza yakadai sekupisa kwakanyanya uye hunyoro hwakanyanya mushure mekushandisa michina yekuchera ine granite bases. Kugadzikana kwakawedzerwa kwekushanda kwemidziyo kunoita kuti mhando yekuchera ive yakavimbika, zvichipa vimbiso yakasimba yekushanda kwakasimba kwenguva refu kwebhodhi rekudzora maindasitiri. Nezvigadzirwa zvemhando yepamusoro, kambani iyi yakabudirira kuvhura misika yevatengi vemaindasitiri yepamusoro, uye huwandu hwebhizinesi rayo hwave huchiwedzera nguva dzose.
Mabhesi egranite, nekugadzikana kwawo kwakanaka, kuomarara kwakanyanya uye kuramba kupfeka, pamwe nekuwedzera kupisa kwakaderera uye kudzikira, anoita basa guru mukuwedzera kugona kwemidziyo yekuboora yePCB. Kubva pakuiswa kwakanyatsonaka uye kuiswa panzvimbo kwayo kusvika pakuwedzera kuomarara kwechimiro chemidziyo, uye kusvika pakushanda kwayo kwakanaka mumamiriro akasiyana-siyana ekugadzira, ese aratidza zvizere kukosha kwawo kwakakosha mukuvandudza kururama kwekuboora uye kushanda zvakanaka kwePCBs. Munzira yekutsvaga kunyatsoita uye kushanda zvakanaka mukugadzira PCB, bhesi regranite pasina mubvunzo ndiro kiyi yekuvhura kugona kwakanyanya kwemidziyo yekuboora yePCB, uye inofanirwa kutariswa zvakanyanya uye kushandiswa kwakakura kwemakambani akawanda ekugadzira emagetsi.
