Uvavanyo olunqamlezayo (ukuncamathela)
Ngokwemigangatho ye-ISO 2409, i-ASTM D3359 okanye i-DIN 53151. Kwiphaneli yovavanyo egqunyiweyo i-cross-cut (i-indentations ngendlela yomnqamlezo kunye ne-parali-lel komnye nomnye kunye nomgama ohlangeneyo we-1 mm okanye i-2 mm) yenziwe ngesinyithi. I-tape eqhelekileyo ifakwe kwi-cross-cut. I-cross-cut ixabiswa ngobuninzi befilimu edibeneyo emva kokususa i-tape.
voco
Iphaneli yovavanyo oluqhelekileyo olugqunyiweyo lugoqwe phezu kwemiqulu yecylindrical (ngokwemigangatho ye-ASTM D1737, ISO 1519 okanye DIN 53152) okanye i-mandrel econical (ngokwemigangatho ye-ASTM D552 okanye i-ISO 6860). Lo ngumlinganiselo wokuguquguquka, ukunweba kunye nokunamathela kwengubo phantsi kwe-deformation. Ezi mvavanyo zisetyenziselwa ukuvavanya amandla okuguqula isithuba samacandelo agqunyiweyo.
Ukuba iipaneli zokuvavanya zigoqwe malunga ne-cylindrical rolls (ene-diameter eyaziwayo) ngoko umphumo ngububanzi bomqulu xa kungekho monakalo kwi-coating.
Ukuba ipaneli yovavanyo isongiwe ngeenxa zonke mandrel conical ke iziphumo zovavanyo ukumela ukuba kungakanani ukwambathisa iqhekeziwe, ukuqala kwicala elibukhali ekusongweni kumphezulu.
Erichsen
Ngokwemigangatho yeDIN 53156 okanye ISO1520. Kolu vavanyo ibhola ephethe i-diameter ethile ityhalwa kwicala elingasemva lokugquma (i-deformation ecothayo). Oku ngesantya esimiselwe kwangaphambili. Ukwaleka kunwenwela kwaye kuqhekeke ekugqibeleni. Ubunzulu bebhola bebhola kwipaneli yokuvavanya xa isambatho siqhekeza, sinqunywe.
Buchholz Ukuqina
Ngokwemigangatho ye-ISO 2815 okanye i-DIN 53153. Olu vavanyo lulinganisa i-deforming, i-indentation yefilimu edibeneyo, xa ivili elikhethekileyo eline-angle elibukhali libekwe phezu komhlaba ngexesha le-30 imizuzwana. Ubulukhuni beBuchholz bulingana ne-100 yahlulwe ngobude be-indentation (mm).
Ukuqina kwePencil
Ngokwesiqhelo ASTM D3363. Kwisixhobo esikhethekileyo iipensile zobunzima obuhlukeneyo (2H, H, F, HB, B, 2B) zibekwe emva kokuba zibukhali kwaye zifakwe. Umgca uzotywe ngepensile. Emva komzobo ngamnye wepensile isambatho siyajongwa kumonakalo.Ubulukhuni bepensile bumele ubulukhuni bepensile obulandelelanayo: enye xa isambatho sasingonakali kwaye enye apho yonakele khona.
UClemen Ubunzima
Ngokwesiqhelo BS 3900:E2, ISO 1518, ASTM D5178. Isetyenziswa njengophawu lokuchasa inkervingen. Ngenaliti yensimbi itsalwa (isantya esimiselweyo kunye noxinzelelo) kwindawo eboshwe. Ngalo lonke ixesha xa umgca utsalwa ngenaliti ubunzima obunzima bubekwe kwinaliti. Okwangoku ukuba isambatho sonakaliswe (inaliti kwintsimbi) ubuninzi bobunzima kwinaliti luphawu lobunzima beClemen.
igalelo
Impembelelo ethe ngqo okanye impembelelo engathanga ngqo: I-ASTM D-2794 ye-ISO 6272.Impembelelo (i-deformation ekhawulezayo) ivavanywa nge-impacttester. Umgaqo uquka ubunzima obuwa ukusuka kwiindawo eziphakamileyo ezihlukeneyo kwindawo edibeneyo (ngokuthe ngqo : kwi-coating, ngokungathanga ngqo kwicala elingasemva lepaneli yovavanyo oludibeneyo). Impembelelo, xa i-indentation kwi-coating ingabonakali impembelelo yokuqhaqha, icatshulwa kwi-kg.cm, kwi-Nm okanye kwi-intshi / iipounds.
Uya kufumana amanqaku amaninzi malunga neempawu zokugquma umgubo.
