Ili ndiye mndandanda wathunthu wosakwaniritsa miyezo yomwe inafalitsidwa ndi International Electrotechnical Commission (IEC).

Ziwerengero za miyezo yakale ya IEC zidasinthidwa mu 1997 powonjezera 60000; mwachitsanzo IEC 27 idakhala IEC 60027. Miyezo ya IEC nthawi zambiri imakhala ndi zikalata zingapo zamagawo; mutu wokha wa muyezo walembedwa pano.

Kuphatikiza kwa utsi Spray mipukutu ndi ukadaulo womwe umagwiritsidwa ntchito kuti upangike pamwamba pa botolo kuti ukhale wowongolera komanso wowala bwino m'mabotolo omwe amathandizidwa. Iyi ndi njira yothandiza kwambiri poyerekeza ndi zowonjezera mkati mwa mabotolo kapena ma preforms, chifukwa sizikhudza katundu wanu. Nthawi zambiri, zowonjezera zimakhudza

Nkhaniyi ikufotokoza kukhazikitsa koyeserera mu mtundu wamaganizidwe kuti muyeze momwe mpweya umagundira, ndikuwunika mtengo wa mpweya wothinikizidwa motsutsana ndi phindu lozizira.

Pakuwumba kuyambitsa kupsinjika kwamphamvu ndikofunikira kwambiri. Nkhani yochokera ku Yunivesite ya Aachen yomwe ili ndi fanizo lazolemba zakufunika kwa kukakamiza kugwira ntchito kwa masanjidwewo.

Kupukuta kwa jakisoni (kuwumba jakisoni ku USA) ndi njira yopangira zinthu popanga mbali mwa kubayira zinthu mu nkhungu. Kupukuta kwa jakisoni kumatha kuchitika ndi zinthu zambiri, kuphatikizapo zitsulo, (zomwe njirayi imatchedwa diecasting), magalasi, elastomers, confsoci, komanso ma polima a thermoplastic komanso thermosetting.

Izi zili ndi njira ziwiri zosiyana, zomwe ndi gawo limodzi komanso magawo awiri. Njira imodzi yokha imagawidwanso pamakina atatu ndi 3-station Makina awiri opangira jekeseni (ISBM), pulasitiki imapangidwa koyamba kukhala "preform" pogwiritsa ntchito jekeseni. Preforms izi zimapangidwa ndi khosi la mabotolo, kuphatikiza ulusi ("kumaliza") kumapeto kwake. Ma preform awa amapakidwa, ndikudyetsedwa pambuyo pake (pambuyo pozizira) mumakina owumbanso otambasula. Pogwiritsa ntchito ISB, ma preforms amatenthedwa (makamaka amagwiritsa ntchito zotenthetsera infrared) pamwamba pa kutentha kwa magalasi, kenako amawombedwa ndikugwiritsa ntchito mpweya wambiri m'mabotolo pogwiritsa ntchito zotumphukira zachitsulo. Preform nthawi zonse amatambasulidwa ndi ndodo yapakati ngati gawo la ndondomekoyi.

Zogulitsa zazikulu za ISO ndi miyezo yapadziko lonse lapansi. ISO imasindikizanso malipoti aukadaulo, maluso aukadaulo, malongosoledwe apagulu, ukadaulo waukadaulo, ndi maupangiri.

Kuzindikira kwa pipeline kumagwiritsidwa ntchito kuti adziwe ngati nthawi zina kutayikira kwachitika mu machitidwe omwe amakhala ndi zakumwa ndi magalasi. Njira zodziwira zimaphatikizapo kuyesa kwa hydrostatic pambuyo pa kukonza kwa mapaipi ndi kudziwonetsa kutayikira panthawi ya ntchito.
