Izikhwama zokufakwa kwe-batch ezincibilikayo eziphansi zenziwe nge-EVA (i-copolymer ye-Ethylene ne-Vinyl Acetate) resin , ngakho zibizwa nangokuthi izikhwama ze-EVA.I-EVA iyi-polymer elastomeric ekhiqiza izinto "ezifana nerabha" ngokuthambile nokuguquguquka. Lesi sici sinokucaca okuhle nokucwebezela, ukuqina kwezinga lokushisa eliphansi, ukumelana nokuqhekeka kwengcindezi, izinto ezinamathelayo ezincibilikayo ezingangeni manzi, kanye nokumelana nemisebe ye-UV. Izicelo zayo zifaka ifilimu, igwebu, izinto zokunamathisela ezincibilikayo ezishisayo, intambo nekhebula, i-extrusion coating, i-solar cell encapsulation, njll.
Izikhwama zethu zokufakwa kwe-batch ezincibilikisiwe eziphansi kanye nefilimu zonke zenziwe nge-virgin EVA resin ukuze kuqinisekiswe ikhwalithi yemikhiqizo yokugcina. Sithatha ikhwalithi yezinto zokusetshenziswa njengento ebalulekile ngoba siyazi ukuthi umkhiqizo wethu uzoba isithako esincane somkhiqizo wakho.
Izikhwama zokufakwa kweqoqo elincibilikayo eliphansi zibhekisela ezikhwameni ezisetshenziselwa ukupakisha izithasiselo zenjoloba namakhemikhali ohlelweni lokuhlanganisa. Ukukhetha izikhwama ezifanele, ngokuvamile sicabangela izici ezilandelayo:
- 1. Iphuzu lokuncibilika
- Izikhwama ezinamaphoyinti ahlukene okuncibilika ziyadingeka ezimweni ezihlukene zokuxutshwa.
- 2. Izinto ezibonakalayo
- Amandla okuqina kanye nokwelula yimingcele yezobuchwepheshe eyinhloko.
- 3. Ukumelana namakhemikhali
- Amanye amakhemikhali angase ahlasele isikhwama ngaphambi kokuba sifakwe kumxube.
- 4. Ikhono lokushisa uphawu
- Ukuvala ukushisa kwesikhwama kungenza ukupakishwa kube lula futhi kunciphise usayizi wesikhwama.
- 5. Izindleko
- Ukushuba kwefilimu nosayizi wesikhwama kunquma izindleko.
Ungase usitshele nje isicelo sakho ohlosile, ochwepheshe eZonpak bazokusiza uhlaziye imfuneko. Futhi kuyadingeka njalo ukuzama amasampula ngaphambi kokusetshenziswa kwenqwaba.
Lo mbuzo besilokhu sibuzwa cishe zonke izinsuku. Impendulo ithi "Cha, asikwazi". Kungani? Nakuba kulula ngathi ukukhiqiza nokuhlinzeka ngemikhiqizo efanayo, siyaqonda ukuthi kuzobangela ukuphazamiseka okukhulu kubasebenzisi nokumosha kwezinsiza okungadingekile. Iningi lemikhiqizo yethu iwuhlobo nosayizi othize wamakhasimende.Sicaphuna intengo kukho konke ukucaciswa okukodwa. Intengo iyahlukahluka kuye ngempahla, ifomu, usayizi, ukujiya kwefilimu, ukugqamisa, ukuphuma, ukuphrinta kanye nezidingo ze-oda. Kwa-Zonpak, sisiza amakhasimende ukuthi ahlaziye izidingo futhi enze ngendlela oyifisayo umkhiqizo olungile ngesilinganiso esingcono kakhulu sokusebenza/intengo.
ZonpakTMizikhwama ezincibilikayo eziphansi kanye nefilimu kuyizinto zokupakisha ezifakwe inqwaba eziklanyelwe ngokukhethekile izimboni zenjoloba, zepulasitiki namakhemikhali. Zinezici ezilandelayo ezivamile.
1. Iphuzu Elincibilikayo Eliphansi
Izikhwama ze-EVA zinamaphuzu athile ancibilikayo aphansi, izikhwama ezinamaphoyinti ahlukene okuncibilika zifanelana nezimo ezihlukene zokuxutshwa. Ukufakwa emshinini wokugaya noma kumxube, izikhwama zingancibilika kalula futhi zihlakazeke ngokugcwele kuma-compounds enjoloba.
2. Ukuhambisana Okuphezulu neRubber nePlastiki
Izinto eziyinhloko esizikhethela izikhwama zethu nefilimu zihambisana kakhulu nerabha namapulasitiki, futhi zingasetshenziswa njengesithako esincane sezinhlanganisela.
3. Izinzuzo Eziningi
Ukusebenzisa izikhwama ze-EVA ukupakisha nokukala kusengaphambili impushana namakhemikhali awuketshezi kungasiza umsebenzi wokuhlanganisa, kufinyelele ukunezela okunembile, kuqede ukulahlekelwa yizimpukane nokungcoliswa, kugcina indawo yokuxuba ihlanzekile.
Iphoyinti lokuncibilika livamise ukuba yisici esibaluleke kakhulu esicatshangelwa umsebenzisi lapho ekhetha izikhwama ezincibilikisiwe ezincibilikayo zokufakwa kwenqwaba noma ifilimu yohlelo lokuhlanganisa iraba. Senza futhi sinikeze izikhwama nefilimu enendawo encibilikayo ehlukene ukuze ivumelane nezimo zezinqubo ezihlukene zamakhasimende. Indawo yokuncibilika ukusuka ku-70 kuya ku-110 deg C. iyatholakala.
