Isikhunta siwumshini oyinhloko wokwenza imikhiqizo ye-FRP. Izikhunta zingahlukaniswa zibe yinsimbi, i-aluminium, usimende, irabha, i-parafini, i-FRP nezinye izinhlobo ngokwezinto ezisetshenziswayo. Izikhunta ze-FRP seziyisikhunta esisetshenziswa kakhulu enqubweni ye-FRP yokubeka ngesandla ngenxa yokwakheka kwazo okulula, ukutholakala kalula kwezinto zokusetshenziswa, izindleko eziphansi, umjikelezo wokukhiqiza omfushane kanye nokugcinwa okulula.
Izidingo zobuso be-FRP molds nezinye i-plastic molds ziyafana, futhi ngokuvamile ubuso be-mold buphakeme ngezinga elilodwa kunomphetho womkhiqizo. Uma ubuso be-mold bungcono, isikhathi sokubumba nesikhathi sokucubungula umkhiqizo sifushane, ikhwalithi yobuso bomkhiqizo iba ngcono, futhi isikhathi eside senkonzo ye-mold. Ngemva kokuba i-mold ilethwe ukuze isetshenziswe, ukuze kulondolozwe ikhwalithi yobuso be-mold, ukugcinwa kwe-mold kumele kwenziwe kahle. Ukugcinwa kwe-mold kufaka phakathi: ukuhlanza ubuso be-mold, ukuhlanza i-mold, ukulungisa umonakalo, kanye nokupholisha i-mold. Ukugcinwa kwe-mold ngesikhathi esifanele nangokuphumelelayo kuyindawo yokuqala yokugcina i-mold. Ngaphezu kwalokho, indlela efanele yokugcinwa kwe-mold iyisihluthulelo. Ithebula elilandelayo libonisa izindlela ezahlukene zokugcinwa kanye nemiphumela yokugcinwa ehambisanayo.
Izindlela ezahlukene zokulungisa izikhunta ezahlukene yilezi ezilandelayo
①Izikhunta ezintsha noma izikhunta ezingasetshenziswa isikhathi eside
Okokuqala, hlanza futhi uhlole ubuso besikhunta, bese wenza ukulungisa okudingekayo ezingxenyeni ezonakele nezingenangqondo zesikhunta. Okulandelayo, sebenzisa isinyibilikisi ukuhlanza ubuso besikhunta, bese usebenzisa umshini wokupholisha kanye ne-polish paste ukuze upholise ubuso besikhunta kanye noma kabili ngemva kokomisa. Qedela ukupholisha nokupholisha kathathu kulandelana, bese upholisha futhi, bese upholisha futhi ngaphambi kokusebenzisa.
②Isikhunta esisetshenziswayo
Okokuqala, qiniseka ukuthi isikhunta siyagcotshwa futhi sipolishwe njalo kathathu, futhi izingxenye ezonakala kalula futhi okunzima ukuzisebenzisa kufanele zicocwe futhi zipolishwe ngaphambi kokusetshenziswa ngakunye. Okwesibili, ukuze uthole ungqimba lwezinto zangaphandle (kungaba yi-polyphenylene noma i-wax) okulula ukuvela ebusweni besikhunta esisetshenziswe isikhathi eside, kumele sihlanzwe ngesikhathi. Sikhuhle kancane), bese ingxenye ekhuhliwe isuswa ngokwesikhunta esisha.
③Esikhumbeni esiphukile
Kuma-mold angenakulungiseka ngesikhathi, ungasebenzisa amabhlogo we-wax nezinye izinto eziguquguquka kalula futhi ezingeke zithinte ukugoba kwe-gel coat ukuze zigcwalise futhi zivikele izingxenye ze-mold ezonakele, futhi ziqhubeke nokusebenzisa. Kulezo ezingalungiswa ngesikhathi, ingxenye eyonakele kumele ilungiswe kuqala, kanti ingxenye elungisiwe kumele ilungiswe ngabantu abangaphansi kuka-4 (ku-25 °C). Ingxenye elungisiwe kumele ipholishwe, ipholishwe futhi isuswe ngaphambi kokuba isetshenziswe.
Ukugcinwa okuvamile nokulungile kobuso besikhunta kunquma impilo yesikhunta, ukuqina kwekhwalithi yobuso bomkhiqizo, kanye nokuqina komkhiqizo, ngakho-ke kumele kube nomkhuba omuhle wokugcinwa kwesikhunta.
