Isku xigxiga BOPA oo Labada Dhinacba La daweeyay Corona
OA2 waa BOPA-da isku xigxiga ee lagu daweeyay corona oo leh astaamo guud oo aad u wanaagsan.Waxaa guud ahaan loo istcimaalaa lakab dhexdhexaad ah iyo habka dusha sare sida daahan iyo codsiga birta.
| Astaamaha | Faa'iidooyinka |
| ✦ Iska caabbinta dabacsanaan wanaagsan; ✦ Xoog wanaagsan iyo iska caabin dalool/saameyn | ✦ Ku habboon qaabeynta baakadaha kala duwan; ✦ Awood u leh baakad culus, fiiqan ama alaab adag oo leh badbaado baakad aad u wanaagsan |
| ✦ Gaaska gaaska oo sarreeya; ✦ Codsiyo aad u fiican oo heerkulkiisu sarreeyo iyo mid hooseeya; ✦ Dhumuc kala duwan; ✦ Hufnaan wanaagsan; ✦ Habaynta | ✦ Kordhi nolosha shelf; ✦ Ku habboon cuntada barafaysan iyo daaqsinka/karrinta; ✦ Dhumucda loo habeeyey shuruudaha xoogga kala duwan-qiimo hufan; ✦ Dareenka tayada wanaagsan; ✦ Si ka wanaagsan u buuxinta shuruudaha macaamiisha |
| Dhumucda / μm | Ballaca/mm | Daawaynta | Dib u celin | Daabacaadda |
| 10 - 30 | 300-2100 | Korona dhinac kaliya | ≤100℃ | ≤6 midab (lagu taliyay) |
Ogeysiis: dib-u-noqoshada iyo daabaciddu waxay ku xidhan tahay macmiisha 'lamination' iyo xaaladda habaynta daabacaadda.

OA2 waxaa loo isticmaali karaa soo saarida baakadaha dabacsan ee 3 midab (oo ay ku jiraan 3 midab), daboolida ballaca≤1cm iyo iyada oo aan shuruud looga dhigin diiwaangelinta daabacaadda, sida bac maran, bacda qaboojiyaha faakuumka, bacaha badeecada biyaha, iyo bacda cadaadiska faakuumka.Codsiyada gaarka ah sida hoos ku xusan, bacda gudaha ee looska (walnuts, miraha gabbaldayaha, iwm.) iyo bacda gudaha ee hilibka (digaag la dubay Texas, steak, iwm.), Baakadaha gaashaanka elegtarooniga ah, baakadaha dareeraha ah, sida khamriga, cabitaanka, suugo , Bacda kaydinta caanaha naaska, bacda kaydinta biyaha, maraq digaag ginseng, bacda saliidda, bacda sanduuqa, cuntada hawada hawada, bacda kalluunka nool, qabow iyo hilibka cusub, cuntada badda, halogen quful baakad cusub, iwm.
Gelitaanka Midabka
Way fududahay in lagu sameeyo qaab dhismeedka NY/PE(CPP).Midabka giraanta karkarinta ayaa ka badan casaan iyo guduud inta lagu jiro habka karinta.Haddii lakabka sare loo beddelo PET giraanta BOPP, ka dib gelitaanka midabka way fududahay in la sameeyo.
Sababaha:
Heerkulka iyo qoyaanka (biyaha) waa labada shay ee aasaasiga ah ee keena dhexgalka midabka.
● Xabagta naylon waa tamar-malaastig ah oo laga soo bilaabo semi-crystal ilaa amorphous.Marka heerkulku kordho, isbeddelka isbeddelka ee u dhexeeya molecules, way sii weyn tahay suurtogalnimada socdaalka midabka.
● Iska caabbinta biyaha naylon waa mid liidata, habka karkarinta, molecules-ka biyaha ee naylon gudaha iyo dibaddaba, ku dhaqaya qaybaha midabka midabka daabacaadda.
● Midabyada qaar ayaa biyo ku milmay.
Talooyinka la xidhiidha:
✔ Isticmaal laba nooc oo dareere ah khad polyurethane.
✔ Ku dar walax daaweyn oo dheeraad ah khad dib loo fasixi karo.
