Iyada oo ah alaab-qeybiyeyaal ka mid ah teknolojiyadda PCB ee PCB, xulashooyinka waqtiga hogaaminta, waxaan heysanaa xulasho agab heer sare ah oo ay tahay xayndaab ballaaran ee noocyada noocyada kala duwan ee PCB-da ay had iyo jeer guriga ku jiraan.
Shuruudaha loogu talagalay waxyaabaha kale ama agab gaar ah ayaa sidoo kale lagu buuxin karaa inta badan kiisaska, laakiin, waxay kuxirantahay shuruudaha saxda ah, ilaa 10 maalmood oo shaqo ayaa loo baahan karaa si loo soo iibsado maaddada.
Na soo xiriir oo ka wada hadal baahiyahaaga mid ka mid ah iibkayaga ama kooxda 'CAM'.

S & A Sida loo tijaabiyo Turnaanta Daloolka Tensile iyo faahfaahinta laxiriira
Sidee loo tijaabiyaa derbiga dersanada godyada iyo faahfaahinta laxiriira? Wall delen ka saar sababaha iyo xalka?
Imtixaanka derbiga derbiga godyada waxaa lagu dabaqay aqalka-godka si loo buuxiyo shuruudaha isuduwaha. Tijaabada guud waa in silig lagu garaacayo gunta PCB iyada oo loo marayo godad ka dibna cabir qiimaha jiidista mitirka xiisadda. Qandaraasyada khibradaha, qiyamka guud waa mid aad u sarreeya, kaas oo ka dhigaya wax dhib ah oo arjiga la sameeyo. Faahfaahinta alaabada ayaa ku kala duwan sida
Shuruudo kaladuwan, waxaa lagu talinayaa in la tixraaco tilmaamaha la xiriira IPC.
Dhibaatada kala go'ida derbiga ah waa arrinta kudhiga saboolka ah, oo guud ahaan sababay laba arrimood oo guud, kan koowaad waa gacanta jahwareerka liita (desska) ayaa ka dhigaya xiisadda inaysan ku filnayn. Midda kale waa hannaanka sawirka cowliga ah ee korantada ee korantada ama midabka tooska ah ee dahabiga ah, tusaale ahaan: koritaanka qaro weyn, xirmooyin waaweyn ayaa sababi doonta saboolnimo sabool ah. Dabcan waxaa jira arrimo kale oo suurtagal ah oo saameyn kara dhibaatadaas, hase yeeshe labadan qodob ayaa ah dhibaatooyinka ugu badan.
Waxaa jira laba faa'iido darrooyin darbi xasaasi ah, dabcan-da dabcan waa bey'ad hawlgal ah oo aad u adag ama adag, waxay ku dambayn doontaa in gudiga PCB uusan u adkeysan karin culeyska jireed si ay u kala go'do. Haddii dhibaatadan ay adagtahay in la xaliyo, laga yaabee inaad tahay inaad beddesho maaddada kamiirka si aad ula kulanto horumar.
Hadeysan aheyn dhibaatada kor ku xusan, waxaa badanaa sabab u ah damiilka saboolka ah ee u dhexeeya naxaasta naxaasta iyo derbiga god. Sababaha suurtagalka ah ee qaybtan oo aan ku filnayn oo ku filnaanaya derbiga god, dhumuc weyn oo naxaas ah, iyo ciladaha is-dhexgalka ee daweynta kiimikada ee saboolka ah. Kuwani dhammaantood waa sabab macquul ah. Dabcan, haddii tayada qoditaanka ay liidato, qaabka kala duwanaanta darbiga godku sidoo kale waxay sababi kartaa dhibaatooyinkaas oo kale. Sida ugu weyn ee shaqada ugu aasaasiga ah ee lagu xaliyo dhibaatooyinkaas, waa inay noqotaa in la xaqiijiyo sababta asalka u ah ka dibna la macaamilo isha sababta ka hor intaanu si buuxda loo xallin.
