Indawo yokwakha udonga lwamakhethini

Udonga lwamakhethini eglasi lusetyenziswa ngokubanzi inkqubo yodonga lwangaphandle. Isikhundla esibalaseleyo kudonga lwangaphandle lwesakhiwo sodonga lwekhethini ayishukumi, kwaye kuye kwakho imisebenzi emininzi emihle. I-Fluorocarbon yokwaleka ibotshelelwe ngokuthe ngqo kwi-adhesive yesakhiwo Enye itywina yolwakhiwo kunye ne-fluorocarbon yokwambathisa yokwambathisa ayifikelelanga kwiimfuno zodonga lomkhusane, ngoko ke isakhelo esifihlakeleyo seglasi yomkhusane amacandelo phakathi kwesakhelo sesibini kunye neglasi, phakathi kwephaneli yokwaleka ye-fluorocarbon amanyathelo okutywinwa ngokudibeneyo kufuneka athathwe. ukuphucula ukunamathela. Kukho iinketho ezininzi: (a) sebenzisa i-primer kwaye emva koko utofe i-adhesive yesakhiwo, kodwa ezinye iingcali zikholelwa ukuba le ndlela ayithembekanga kwaye yeyalo "lwesikhumba esine-two-layer", kwaye akukho ngxelo eqinisekisayo eqinisekisa ukuba le ndlela ilungile. ngempumelelo, ngoko ke uqwalaselo olongezelelweyo nophando luyafuneka; (b) ulwakhiwo lweprofayili edibeneyo yamkelwa, inxalenye encamathelayo yolwakhiwo oludityanisiweyo ngokuthe ngqo yahlulwe kuyo yonke iprofayili, kwaye icandelo elincamathelayo lesakhiwo lidityaniswe ngokuthe ngqo; (c) Ngexesha lokutshiza nge-fluorocarbon, inxalenye yebhondi kufuneka ikhuselwe ukugcina umphezulu une-anodized; (d) thatha amanyathelo okulungisa ngokususa i-coating yobuso ukuze iboshwe nge-sandpaper, njl., nge-oxidation yendalo (malunga ne-5um). Uqhagamshelo lwepini yokucofa ngokwakho ludibaniso oluqhelekileyo okanye uqhagamshelo lokubeka indawo, njengodibaniso lwesakhiwo sodonga lomkhusane, ukuthembeka kwalo kubi. Xuba iiprofayili zentsimbi kunye ne-aluminiyam Umphezulu wangaphakathi wombhobho wentsimbi yesikwere akukho lula ukufikelela kunyango lwe-peening, kwaye ingxaki yomgangatho kulula ukwenzeka ngexesha lokugalela idiphu eshushu, okukhokelela ekuxhathiseni umhlwa okuphantsi. Intsimbi kunye ne-aluminium yokulinganisa i-gap kufuneka ibe nzima, ngaphandle koko amandla adibeneyo angenakufezekiswa, okubangela ubunzima bokuthintela ukwenzeka kwe-bimetal electrochemical corrosion. Idlala elifutshane Vula udonga lwesakhelo somkhusane kwamkela ukuhlangana kwamadlala, kwelinye icala, kulula ukuqonda i-isobaric cavity, kwelinye icala, inokubotshwa ngesigqubuthelo sebuckle. Ukusetyenziswa kwe-discontinuous gland (i-short gland), nangona kunokunciphisa iindleko, kodwa kuya kubakho iglasi engalinganiyo kunye nezinye iingxaki. Iziqwenga zoqhagamshelo phakathi kweentsika zomqadi ziqhagamshelwe ngamanqaku amabini Umqadi wodonga lwamakhethini uhlala ubonakala "intloko yesithulu yokutsalwa" isiganeko, izizathu zayo zinokuba: (1) I-Beam ethwele umthamo wodonga lwanamhlanje aluhambelani neemfuno; (2) umdibaniso phakathi komqadi kunye nentsika ubuthathaka ngokwentelekiso, njengokudityaniswa phakathi kwentsika yomqadi kusetyenziswa iibholithi ezimbini, ngenxa yokungaqhubi kakuhle kwayo, nto leyo ekhokelela ekunyakazelekeni komqadi wodonga lomkhusane.
