In Ingxenye I sidlule ezinyathelweni zokwenza isikhunta se-silicone. Manje sesilungele ukusakaza ingxenye yangempela. Ingabe usukulungele lokhu?

Kulungile, ngakho-ke lapho usakaza izingxenye zepulasitiki zesibonelo unokuningi okukhethiwe kwezinto ongakhetha kuzo kulezi zinsuku. Ukukhethwa kwama-resin kuphela kuyamangalisa ngempela. Ungaphonsa izingxenye usebenzisa izinto ezahlukahlukene, kufaka phakathi ama-Polyurethanes, ama-Epoxies, amaPolyester ashibhile, noma amaSilicone. Sizosebenzisa i-Urethane resin kule phrojekthi. Ake sihlukanise lokho ozodinga.

Okokuqala, ake sibheke futhi sihambe ngenqubo.

Izinyathelo

Isinyathelo 1: Khetha i-resin efanele yohlelo lwakho lokusebenza

Kule phrojekthi yokuphonsa ngisebenzise i-IE3076 Polyurethane resin kusuka Ama-Polymers amasha Lolu hlobo lwe-resin luvame ukubizwa ngokuthi i-Urethane resin. Iza ngobulukhuni obuhlukahlukene futhi. Hlola nomkhiqizi wakho ukuthi iyiphi impahla efanele yohlelo lwakho lokusebenza. Ngithanda ukusebenzisa i-3076 njengoba iyindawo enhle nxazonke ngenxa yempilo ende yebhodwe cishe imizuzu eyi-1215, namandla amahle kakhulu nekhono lokulingisa ingxenye ye-ABS ebunjiwe yomjovo. Ukuphila kwebhodwe kubhekisela esikhathini esithatha impahla ukuze ijeli ngaphambi kokuba ungabe usakwazi ukuyithela noma ukuyisebenzisa ngempumelelo.

Isinyathelo 2: Setha futhi Hlanganisa

Uma usuyikhethile i-resin efanele sekuyisikhathi sokuqala ukuphonsa noma ukujova ukubumba izingxenye zakho esikhunjeni se-silicone. Bheka Ingxenye I lapha ukuze uthole ulwazi mayelana nokwenza isikhunta esinezingxenye ezimbili ze-silicone. Ngizobe ngisakaza ikhamera yangokwezifiso ye-Joby hotshoe SR71 Unity engiyiklamile.

Ama-resin ahlanganiswe ngezindlela ezimbili. Ngesisindo noma ngevolumu. Ngizosebenzisa indlela yesisindo njengoba kukhonjisiwe ku le vidiyo. Ngisebenzisa isikali sekhishi esidijithali esisethwe ukuze sibe amagremu, okwenza kube lula kimina ukuhlanganisa isisindo. Ngisebenzisa nezinkomishi zepulasitiki ezishintshashintshayo, ezilahlwayo, zesitolo segrosa ukuhlanganisa yonke into. Ngisika isikali sibe kuZiro ngenkomishi yepulasitiki bese ngengeza ingxenye yokuqala yengxube yezingxenye ezimbili. Ngivame ukuqala ngokuqina kwezingxenye ezimbili - kulokhu i-resin. Uma nginenani le-resin engiyidingayo emsebenzini, ngingakwazi ukwengeza umbala uma kudingeka noma ngiyidaka ukuze ngingeze okokuqinisa.

Ngilungisa isibali-sikhathi sami sasekhishini esidijithali njengamanje, ngoba kuwumbono omuhle ngempela ukulandelela isikhathi sokuhlanganisa, ikakhulukazi uma usebenzisa ithangi lokuhlanza ukuze ukhiphe impahla yakho. Ngenza isiqiniseko sokuthi ngidwengula isikali bese ngiqala isibali sikhathi, bese ngengeza i-hardener. Uzoqaphela ukuthi ngisebenzisa induku yokuxuba eluhlaza okwesibhakabhaka hhayi isicindezeli solimi sokhuni ukuxuba izingxenye ezimbili. Lezi zinti ngaziphonsa ezinhlakeni ezisele. Isizathu sokuthi ngisebenzise induku yokuxuba ipulasitiki ukugcina umswakama ungangeni kungxube. I-Urethane isengozini yomswakama futhi induku yokuxuba yokhuni ingakhulula umswakama ku-resin yakho. Ngizama ukugwema amabhamuza omoya engxenyeni yami ukuze ugcine umswakama ubuncane kubalulekile. Futhi nginesikhunta esilungele ukuhamba kusenesikhathi, siboshelwe kanye nebhodi eliqinile nebhande lenjoloba.

Isinyathelo 3: I-Degas ku-vacuum tank

Emuva kwemizuzu engaba mibili yokuxutshwa okunamandla nokunwaya izinhlangothi zenkomishi yepulasitiki, sekuyisikhathi sokubeka ingxube ethangini le-vacuum ukuze kukhishwe umoya. Lokhu kubalulekile ukwenza izingxenye eziphelele ezingenabhamuza. Inhloso yethangi levacuum ukukhipha umoya ngaphakathi ekamelweni. Ngibeka inkomishi yami exubile ye-resin ethangini bese ngiqala ukukhipha umoya ovaleleke ku-urethane. Ungabona i-resin 'amabhamuza e-cocktail'–lokhu umoya osuswa ku-resin. Uma amabhamuza omoya eyeka ukwakheka phezulu kwengxube, uyazi ukuthi uwususile wonke umoya ovalelekile futhi ungawususa ethangini bese uqala ukuwujova esikhunjeni sakho se-silicone.

Isinyathelo 4: Jova i-resin noma uthele esikhunjini

Ngithanda ukujova izingxenye zami. Kungivumela ukuthi ngithole ngokushesha izinto eziwugqinsi zibe isikhunta esiyinkimbinkimbi kalula kakhulu. Ngimane ngimunca inhlaka kusisirinji bese ngiyifaka kancane kancane esibunjeni sami. Le ndlela ingivumela ukuba ngisebenzise cishe noma iyiphi impahla ewugqinsi. I-resin ye-3076 incane kakhulu ngakho-ke akunzima kakhulu ukuyijova, kodwa kuma-urethanes aminyene nama-silicones, noma izinto ezingenayo impilo yebhodwe elide, kuyindlela ebaluleke kakhulu.

Isinyathelo 5: Beka ngaphansi kwengcindezi ethangini lokucindezela (uyazikhethela)

Njengoba ngizama ukwenza ingxenye eqinile engenabhamuza, ngibeka isikhunta se-silicone nenhlaka ethangini lami lokucindezela elishisayo. Umfutho osethangini ukhama noma yimaphi amabhamuza omoya asele (uma kukhona abonakalayo) wehlele ezingeni elincane kakhulu. Lokhu kushisa ethangini nakho kunomphumela wokusheshisa isikhathi sokwelashwa kwe-resin. Lokhu kuzophinde kusheshise izikhathi zakho zedemold futhi kungaba yinzuzo uma udinga ukudala izingxenye ezimbalwa ngesikhathi esifushane.

Isinyathelo 6: Demold

Cishe sesifikile. Ngemva kwamahora ambalwa ebhodweni lokucindezela elishisayo, i-resin imisiwe futhi isilungele ukukhishwa ethangini kanye nesikhunta se-silicone. Sekuyisikhathi sokuthi sidicilele phansi ingxenye yethu futhi sibone ukuthi sinabalingisi abaphumelelayo.

Vele ube mnene lapho ususa izingxenye zakho kusikhunta sakho se-silicone. Uma uqaphele futhi ubaphathe kahle ungathola izingxenye ezingu-50, akunankinga. Lesi sikhunta sinama-undercuts kanye nemicu, futhi sengijikijele inqwaba yezingxenye kuze kube manje lapho isikhunta sibambelele kahle. Kuye ngokuthi isikhunta sakho siphuma kanjani, ungase ube nokuhlanza okuncane; i-flash ethile ezosikwa. Endabeni yami, bekungekho ukukhanya okufanele sikhathazeke ngakho, ngakho-ke qaphela nje ukuthi imayela lakho lingahluka.
