Bhodhi rakagadzirwa nearuminiyamu nepurasitiki chinhu chitsva chekushongedza. Nekuda kwekushongedza kwaro kwakasimba, kune mavara, kunogara kwenguva refu, huremu hwaro hushoma uye kuri nyore kugadzirisa, rakagadzirwa nekukurumidza uye rinoshandiswa zvakanyanya kumba nekune dzimwe nyika.
Mukuona kwevanhuwo zvavo, kugadzirwa kwebhodhi re aruminiyamu-purasitiki rakanyatsojeka, asi kutaura chokwadi inyaya yezvigadzirwa zvitsva zvakawanda. Saka, kudzora mhando yezvigadzirwa zve aruminiyamu-purasitiki zvakasanganiswa kune dambudziko guru rehunyanzvi.
Zvinoteveravarizvinhu zvinokanganisa simba remaganda ealuminium ne180° - purasitiki yakabatanidzwabhodhi:
Hunhu hwefoil yearuminiyamu pachahwo idambudziko. Kunyangwe iri riri dambudziko rakavanzika, rakaratidzwa muhunhu hwemapaneru earuminiyamu-purasitiki. Kune rumwe rutivi, inzira yekurapa kupisa kwearuminiyamu. Kune rumwe rutivi, mamwe aruminiyamubhodhiVagadziri vanoshandisa marara ealuminium akadzokororwa vasina kudzora mhando zvakanyanya. Izvi zvinoda kuti mugadziri wemapuranga epurasitiki ealuminium aongorore zvakakwana mugadziri wezvinhu, agadzire vanhu vebhizinesi uye ave nechokwadi chekuti zvinhu zvacho zvakanaka mushure mekusarudza makambani madiki akakodzera.
Kugadziriswa kwealuminium karebhodhiHunhu hwekuchenesa nekuisa lamination yearuminiyamubhodhizvine chekuita zvakananga nehunhu hwepurasitiki yealuminiumbhodhiAruminiyamubhodhiinofanira kutanga yacheneswa kubvisa mavara emafuta netsvina pamusoro, kuitira kuti pamusoro payo pave nechikamu chakakora chemakemikari, kuitira kuti firimu repolymer rigone kugadzira chisungo chakanaka. Zvisinei, vamwe vagadziri havanyatso dzora tembiricha, kuomerera, nguva yekurapa uye kugadziridzwa kwemvura panguva yekurapa, nokudaro zvichikanganisa kunaka kwekuchenesa. Pamusoro pezvo, vamwe vagadziri vatsva vanoshandisa jira rearuminiyamu zvakananga vasina kurapwa. Zvese izvi zvinotungamira kumhando isina kunaka, simba rakaderera rekubvisa 180° kana kusagadzikana kwemusanganiswa.
Kusarudzwa kwezvinhu zvepakati. Zvichienzaniswa nemamwe mapurasitiki, mafirimu epolymer anonyatsobatanidzwa nepolyethylene, anodhura zvishoma, haana chepfu uye ari nyore kugadzirisa. Saka zvinhu zvepakati ipolyethylene. Kuti vaderedze mitengo, vamwe vagadziri vadiki vanosarudza PVC, iyo ine bonding isina kunaka uye inogadzira magasi ane chepfu anouraya kana apiswa, kana kusarudza zvinhu zvakadzokororwa zvePE kana kushandisa zvinhu zvePE zvakasanganiswa ne substrate. Nekuda kwemhando dzakasiyana dzePE, kukwegura uye zvichingodaro, izvi zvinotungamira kukupisa kwakasiyana kwe compounding, uye hunhu hwekupedzisira hwe compounding pamusoro huchava husina kugadzikana.
Sarudzo yefirimu repolymer. Firimu repolymer rudzi rwezvinhu zvinonamira zvine hunhu hwakakosha, izvo zvinonyanya kukanganisa kunaka kwezvinhu zvakasanganiswa. Firimu repolymer rine mativi maviri uye rinoumbwa nezvikamu zvitatu zvakasanganiswa. Rutivi rumwe rwakabatanidzwa nesimbi uye rumwe rutivi rwakabatanidzwa nePE. Rutivi rwepakati iPE base material. Hunhu hwemativi ese akasiyana zvachose. Pane musiyano mukuru mumitengo yezvinhu pakati pemativi maviri. Zvinhu zvine chekuita nearuminiyamubhodhiMaworkshop anofanirwa kutengwa kunze kwenyika uye anodhura. Zvinhu zvakasanganiswa nePE zvinogona kugadzirwa muChina. Nokudaro, vamwe vagadziri vemafirimu epolymer vanonetseka nezveizvi, vachishandisa zvinhu zvakawanda zvakanyungudutswa zvePE, vachicheka makona uye vachiwana purofiti yakakura. Kushandiswa kwemafirimu epolymer kwakananga uye kumberi nekumashure hazvigone kutsiviwa. Firimu repolymer rudzi rwefirimu rinozviparadza, kunyunguduka kusina kukwana kunotungamira mukudzokororwa kwenhema. Simba rekutanga rakawanda, nguva yakareba, simba rinodzikira nekuda kwemamiriro ekunze, uye kunyange mabhuru kana chitarisiko chemazino chinoonekwa.
