Chii chiri hukama huripo pakati pekusimba kwekusimba kwefoil yemhangura nekureba kwayo?

Simba rekudhonza uye kureba kwefoil yemhangurazviratidzo zviviri zvakakosha zvehunhu hwemuviri, uye pane hukama hwakati pakati pazvo, izvo zvinokanganisa zvakananga kunaka uye kuvimbika kwepepa remhangura.

Simba rekudhonza rinoreva kugona kwefoiri yemhangura kuramba kutyoka kwekudhonza pasi pesimba, rinowanzoonekwa mu megapascals (MPa). Kureba kunoreva kugona kwechinhu chacho kuchinja purasitiki panguva yekutambanudza, kunoratidzwa sechikamu. Simba rekudhonza nekureba kwefoil yemhanguraZvinokanganiswa panguva imwe chete nehukobvu nehukuru hwezviyo, uye tsananguro yehukuru uhwu inofanira kuunza chiyero chehukuru hwezviyo zvisina dimension (T/D) separamita yekuenzanisa. Patani yekusiyana kwesimba rekudhonza yakasiyana muhuwandu hwehukuru hwezviyo hwakasiyana, nepo kureba kuchiderera nekudzikira kwehukobvu kana chiyero chehukuru hwezviyo chakangofanana.

Mukushandiswa kunoshanda, senge mukugadziramabhodhi edunhu akadhindwa(PCBs), mitemo inonzwisisika yekusimba kwekusimba uye kureba kwesimba rekubata zvinogona kuve nechokwadi chekuti chigadzirwa hachiwanzo tyoka kana kuchinja panguva yekushandiswa, nokudaro zvichivimbisa kunaka uye kuvimbika kwechigadzirwa. Pakuyedzwa kwekusimba kwesimbi yesimbi yemhangura, kune mitemo yakasiyana-siyana uye nzira dzekuziva hunhu uhwu, senge IPC-TM-650 2.4.18.1A standard, iyo yakagadzirirwa zvakananga simbi yesimbi yemapuranga edunhu akadhindwa uye inopa nzira dzakadzama dzekuedza uye mapoinzi.

Pakuyedza simba rekudhonza uye kureba kwefoil yemhangura, zvinhu zvekufunga nezvazvo zvinosanganisira saizi yemuenzaniso, kumhanya kwekuyedza, mamiriro ekupisa, nezvimwewo. Semuenzaniso, chiyero cheASTM E345-16 chinopa nzira dzekuyedza foil yesimbi, kusanganisira maparameter akadzama akadai sehukuru hwemuenzaniso, kumhanya kwekuyedza, nezvimwewo. Chiyero cheGB/T 5230-1995, kune rumwe rutivi, chinotsanangura zvinodiwa zvekuyedza foil yemhangura yemagetsi, kusanganisira saizi yemuenzaniso, kureba kwegeji, daro riri pakati pemaclamp, uye kumhanya kweclamp yemuchina wekuyedza.

Muchidimbu, simba rekudhonza uye kureba kwefoil yemhangura zviratidzo zvikuru zvekuyera hunhu hwayo hwepanyama, uye hukama hwavo nenzira dzekuyedza zvakakosha pakuona kunaka uye kushanda kwekushandisa kwayo.foil yemhangurazvinhu.
