Indawo yokwakha udonga lwamakhethini

Udonga lwamakhethini engilazi luyisistimu yodonga lwangaphandle olusetshenziswa kabanzi. Isikhundla esivelele odongeni lwangaphandle lwesakhiwo sodonga lwamakhethini asinyakazi, futhi kuye kwaba nemisebenzi eminingi emihle. Ukunamathela kwe-fluorocarbon kuhlanganiswe ngokuqondile nokunamathelayo kwesakhiwo Okunye ukubopha kwesakhiwo sealant kanye ne-fluorocarbon enamathelayo akufinyeleleki ezimfuneko zodonga lwamakhethini, ngakho-ke izingxenye zodonga lwekhethini yengilazi yohlaka olufihliwe phakathi kohlaka lwesibili nengilazi, phakathi kwephaneli le-fluorocarbon enamathelayo kufanele kuthathwe izinyathelo zokuvala ngokuhlanganyela. ukuthuthukisa ukunamathela. Kunezinketho ezimbalwa: (a) sebenzisa i-primer bese ujova i-adhesive yesakhiwo, kodwa abanye ochwepheshe bakholelwa ukuthi le ndlela ayithembekile futhi ingeye "isikhumba esinezingqimba ezimbili", futhi ayikho imibiko eqinisekisayo eqinisekisayo ukuthi le ndlela ngempumelelo, ngakho-ke kudingeka ukubhekwa nokucwaninga okwengeziwe; (b) kwamukelwa ukwakheka kwephrofayili eyinhlanganisela, ingxenye enamathelayo yesakhiwo eboshwe ngokuqondile ihlukaniswa nayo yonke iphrofayili, futhi ingxenye enamathelayo yesakhiwo eboshelwe ngokuqondile i-anodized; (c) Ngesikhathi sokufuthwa kwe-fluorocarbon, ingxenye yokubopha kufanele ivikelwe ukuze igcine ingaphezulu ligcotshwe; 15 Uxhumano lwephinikhodi lokuzithepha ngokwakho ukuxhumana kwephinikhodi kuwuxhumano olujwayelekile noma uxhumano lokubeka indawo, njengoxhumano lwesakhiwo sodonga lwamakhethini, ukwethembeka kwalo kubi. Hlanganisa amaphrofayili ensimbi ne-aluminium Indawo engaphakathi yepayipi lensimbi eyisikwele akulula ukuthola ukwelashwa kokuchama, futhi inkinga yekhwalithi iyenzeka kalula ngesikhathi sokushiswa kwediphu elishisayo, okuholela ekumelaneni nokugqwala okuphansi. Igebe elihambisana nensimbi ne-aluminium kufanele liqine ngokuqhathaniswa, ngaphandle kwalokho amandla ahlangene angeke afinyelelwe, okubangela ubunzima ukuvimbela ukwenzeka kwe-bimetal electrochemical corrosion. Indlala emfishane Vula udonga lwekhethini lohlaka luthatha ukubopha kwezindlala, ngakolunye uhlangothi, kulula ukubona i-isobaric cavity, ngakolunye uhlangothi, ingaboshelwa ngesembozo sebhande. Ukusetshenziswa kwe-discontinuous gland (i-short gland), nakuba kunganciphisa izindleko, kodwa kuyoba khona ingilazi engalingani nezinye izinkinga. Izingcezu uxhumano phakathi izinsika ugongolo axhunywe amaphuzu amabili Curtain odongeni ugongolo ngokuvamile livela "izithulu ukudonsa ikhanda" mkhuba, izizathu zayo zingase zibe: (1) Beam ezithwala umthamo wesimanje ikhethini odongeni ayihlangabezani nezidingo; (2) ukuxhumana phakathi kwenduku nekholomu kubuthaka uma kuqhathaniswa, njengokuxhuma phakathi kwekholomu yegxolo kusetshenziswa amabhawudi amabili, ngenxa yokungaqhubi kahle kwayo okuguquguqukayo, okuholela ekunyakaziseni kodonga lwamakhethini.
