EVAyenziwe nge-copolymerization ye-ethylene (E) ne-vinyl acetate (VA), ebizwa ngokuthi i-EVA, futhi iyinto evamile ephakathi nendawo. I-EVA wuhlobo olusha lwezinto zokupakisha ezinobungani bemvelo. Yenziwe ngegwebu le-EVA, elinqoba ukushiyeka kwenjoloba yegwebu evamile njengokuqina, ukubola, nokululama okungekuhle. Inezinzuzo eziningi ezifana nobufakazi bamanzi nomswakama, ukushaqeka, ukuvala umsindo, ukugcinwa kokushisa, ipulasitiki enhle, ukuqina okuqinile, ukuvuselela kabusha, ukuvikelwa kwemvelo, ukumelana nomthelela, ukumelana nokushelela nokushaqeka, njll. Iphinde ibe nokuphikiswa okuhle kwamakhemikhali futhi i into efanelekile yokupakisha yendabuko. ezinye izindlela. I-EVA inepulasitiki enamandla kakhulu. Inganqunywa ngokufa kunoma yikuphi ukuma, futhi ingenziwa ngezifiso ngokusho kwemidwebo yamakhasimende. Isikhwama sokugcina se-EVA singenziwa ngendlela oyifisayo ngombala, indwangu kanye nolayini oludingwa ikhasimende. I-EVA isetshenziswa kabanzi ku-shockproof, anti-slip, uphawu kanye nokugcinwa kokushisa kwezinto zikagesi, ulwelwesi lwamabhokisi okupakisha ahlukahlukene, amathini ensimbi nezinye izimboni. Imisebenzi njengokuvikela, i-anti-static, i-fireproof, i-shockproof, ukugcinwa kokushisa, i-anti-slip, ne-fixed. Ingagugi futhi imelana nokushisa. I-Insulation neminye imisebenzi.
Igama lesayensi le-EPE yi-polyethylene enwebekayo, eyaziwa nangokuthi ukotini weparele. Iwuhlobo olusha lwezinto zokupakisha ezinganciphisa futhi zimunce ukudlidliza. Kungumkhiqizo we-polyethylene enegwebu eliphezulu okhishwe ku-polyethylene e-low-density (LDPE) njengento eluhlaza eyinhloko. I-EPE pearl cotton ifakwe amagwebu ibe yizimo ezikhethekile kusetshenziswa i-butane, okwenza i-EPE inwebeka kakhulu, iqine kodwa ingabi brittle, nengaphezulu elithambile. Ingavimbela ngempumelelo umonakalo odalwe ukungqubuzana ngesikhathi sokupakishwa komkhiqizo futhi inezici ezinhle kakhulu zokumunca nokungamelani nokushaqeka. . Manje isisetshenziswa kabanzi ekufakweni kwezinto zikagesi, ifenisha, izinsimbi zikagesi ezinembayo neminye imikhiqizo. I-EPE pearl cotton iqinile ngokumelene nowoyela wemishini, amafutha, njll. Ngenxa yokuthi iwumzimba webhamuza, ayinawo nhlobo ukumuncwa kwamanzi. Kungaba uwoyela, umswakama-umswakama, ukushaqeka, ukuvala umsindo kanye nokushisa ukushisa, futhi kungamelana nokuguguleka kwezinhlanganisela eziningi. I-EPE pearl ukotini ingahlangabezana nezidingo ezahlukene zokupakisha, i-antistatic, i-flame retardant, njll ngokuvumelana nezidingo zemikhiqizo ehlukene. Iphinde ibe nemibala ecebile futhi kulula ukuyicubungula.
Igama lesayensi lesipontshi yirabha yegwebu ethambile ye-polyurethane, esetshenziswa ngokusobala ekumunceni ukushaqeka, ukulwa nokungqubuzana, nokuhlanza. Izinhlobo zihlukaniswe zibe isipontshi se-polyester nesipontshi se-polyether, ezibuye zihlukaniswe zibe izinhlobo ezintathu: i-rebound ephezulu, i-rebound ephakathi kanye ne-slow rebound. Isiponji sithambile ekuthunjweni, simelana nokushisa (singamelana nezinga lokushisa lama-degree angu-200), futhi kulula ukushiswa (ama-flame retardants angengezwa). Kuye ngobukhulu bamabhamuza angaphakathi, ingabonisa ukuminyana okuhlukahlukene futhi ingabunjwa ibe yizimo ezihlukahlukene njengoba kudingeka. Inokusetshenziswa okubanzi futhi isetshenziswa kakhulu ekushaqekeni, ekushiseni okushisayo, ukugcwaliswa kwezinto ezibonakalayo, amathoyizi ezingane, njll.
Umehluko omkhulu phakathi kokuthathu umi kanje:
1. Siyawubona umehluko phakathi kwabo ngamehlo enyama. Isipontshi silula kulezi zintathu. Iphuzi kancane futhi inwebeka. I-EVA iyona esindayo phakathi kwamathathu. Imnyama futhi iqinile. I-EPE pearl ukotini ibonakala imhlophe, okulula ukuyihlukanisa nesipontshi. Isipontshi sizobuyela ngokuzenzakalelayo esimweni saso sasekuqaleni kungakhathaliseki ukuthi usicindezela kanjani, kodwa ukotini we-EPE pearl uzobohloka futhi wenze umsindo ophumayo lapho usicindezela.
2. Ungabona amaphethini we-wavy kukotini we-EPE pearl, njengegwebu eliningi elihlanganiswe ndawonye, kuyilapho i-EVA inomumo futhi ingahlukaniswa ngokuvumelana nokugxila kwayo.
