Kumapayipi ensimbi angu-20# anobukhulu bodonga obufika ku-87mm, ubuqotho bangaphakathi bubaluleke kakhulu, njengoba ngisho nemifantu emincane kakhulu kanye nokungcola kungalimaza kakhulu ubuqotho besakhiwo nokusebenza kwawo, futhi ukuhlolwa kwe-ultrasonic kungawabona ngempumelelo la maphutha angaba khona.
Ukuhlolwa kwe-Ultrasonic, okubizwa nangokuthi i-UT, kuyindlela yokuhlola engonakalisi esebenzisa izakhiwo zokubonakalisa, ukubuyisa, kanye nokunciphisa amagagasi e-ultrasonic njengoba esakazeka ngezinto ukuze kutholakale amaphutha ngaphakathi kwezinto.
Uma igagasi le-ultrasonic lihlangana neziphambeko ngaphakathi kwezinto ezifana nemifantu, ukufakwa noma imigodi, amagagasi abonakalisiwe azokhiqizwa, futhi indawo, ukuma kanye nosayizi weziphambeko kunganqunywa ngokwamukela la magagasi abonakalisiwe.
Ngokuhlola ngokucophelela, kuqinisekisa ukuthi ipayipi lensimbi lilonke alinazo iziphambeko futhi lihambisana ngokugcwele nezindinganiso kanye nezidingo zamakhasimende.
I-Botop ingumkhiqizi wepayipi lensimbi elihlanganisiwe ochwepheshe futhi othembekile kanye nomthengisi wepayipi lensimbi elingenamthungo eShayina, ikunikeza imikhiqizo yepayipi lensimbi enekhwalithi ethembekile kanye nentengo encintisanayo. Sithembisa ukusekela inhlangano yokuhlola yeqembu lesithathu yazo zonke izimpahla esizithengisayo, futhi sizohlela abahloli ukuthi baphinde bahlole amapayipi ensimbi lapho iqembu ngalinye lamapayipi ensimbi lilethwa ukuqinisekisa ikhwalithi yamapayipi ensimbi futhi.
I-GB/T 8162 iyincazelo ejwayelekile ekhishwe yiShayina ye-amapayipi ensimbi angenamthungongezinhloso zesakhiwo. I-20# iyizinga elivamile lensimbi yekhabhoni enezakhiwo ezinhle zemishini nezokucubungula, esetshenziswa kabanzi ezakhiweni zokwakha kanye nezakhiwo zemishini.
Izidingo ze-GB/T 8162 Grade 20 zokwakheka kwamakhemikhali kanye nempahla yemishini yilezi ezilandelayo:
Ukwakheka Kwamakhemikhali kwe-GB/T 8162 Ibanga lama-20:
