Ulwazi

Lolu uhlu olungapheleli lwamazinga ashicilelwe i-International Electrotechnical Commission (IEC).

Amanani wamazinga amadala we-IEC aguqulwa ngonyaka we-1997 ngokungeza ama-60000; Isibonelo, i-IEC 27 iba yi-IEC 60027. Izindinganiso ze-IEC zivame ukuba nemibhalo engezansi yengxenye; isihloko kuphela esiyindinganiso esibhalwe lapha.

I-Spray coating coating, ubuchwepheshe obusetshenziselwa ukumboza ingaphezulu kwebhodlela ukuze uthuthukise izindawo ezinamaphiko eziphathwayo nezikhanyayo. Le ndlela isebenza kahle kakhulu ngokuqhathanisa izengezo ngaphakathi kwamabhodlela noma ama-preforms, ngoba azithinti izakhiwo ezibonakalayo. Imvamisa, izengezo zinomthelela

Le ndatshana ichaza ukusetha kokuhlola kumodeli yokuqhathanisa ukukala umthelela womoya ovuthayo, kanye nokuhlola izindleko zomoya ocindezelwe ngokumelene nokuthola okupholile kokuzuza.

Ekushayeni ukubumba ingcindezi yokushaywa kubaluleke kakhulu. Isihloko esivela eNyuvesi yase-Aachen esinemodeli yokucabanga ngokubaluleka kwengcindezi ekusebenzeni kwejometri engaphezulu.

Ukufakwa ngenaliti (ukujova ngomjovo e-USA) inqubo yokukhiqiza yokukhiqiza izingxenye ngokujova impahla kukhunta. Ukufakwa kokulimala kungenziwa ngezinto eziningi, kufaka phakathi izinsimbi, (lapho inqubo ibizwa ngokuthi i-diecasting), izingilazi, ama-elastomers, ukuhlangana, kanye nama-polymer evamile kakhulu we-thermoplastic kanye ne-thermosetting.

Lokhu kunezindlela ezimbili eziyinhloko ezehlukene, okungukuthi inqubo yesigaba esisodwa nesigaba esimbili. Inqubo yesigaba esisodwa iphinde yehlukaniswe yaba imishini yesiteshi esine-3 kanye nesiteshi esine-4 Enqubeni yezinqubo ezimbili zomjovo wokunwebeka komjovo (ISBM), ipulasitiki iqale ibunjwe ibe yi "preform" kusetshenziswa inqubo yokubumba umjovo. Lawa ma-preform akhiqizwa ngezintamo zamabhodlela, kufaka phakathi imicu ("ukuphela") ngakolunye uhlangothi. Lawa ma-preform afakwa emaphaketheni, bese ondliwa ngokuhamba kwesikhathi (ngemuva kokupholisa) kumshini wokubumba wokuphinda usebenzise kabusha. Enqubeni ye-ISB, ama-preforms ayashiswa (imvamisa kusetshenziswa ama-infrared heater) ngaphezu kokushisa kwengilazi yabo yokushintshwa, bese kushaywa kusetshenziswa umoya ophakeme kakhulu ube ngamabhodlela kusetshenziswa isikhunta segalelo lensimbi. I-preform ihlala yelulwa ngenduku eyinhloko njengengxenye yenqubo.

Imikhiqizo eyinhloko ye-ISO yizindinganiso zomhlaba jikelele. I-ISO iphinde ishicilele imibiko yezobuchwepheshe, imininingwane yezobuchwepheshe, imininingwane etholakala esidlangalaleni, i-technical corrigenda, kanye nemihlahlandlela.

Ukutholwa kokuvuza kwepayipi kusetshenziselwa ukuthola ukuthi kanti kwezinye izikhathi lapho kuvuza khona kwenzeka ezinhlelweni eziqukethe uketshezi nezibuko. Izindlela zokutholwa zifaka ukuhlolwa kwe-hydrostatic ngemuva kokuqanjwa kwamapayipi nokutholwa okuvuzayo ngesikhathi senkonzo.
