Waa maxay Rinjiga Polyethylene
Rinjiga polyetylen, oo sidoo kale loo yaqaan dahaarka caagga ah, ayaa ah dahaarka lagu dhejiyo alaabta caagga ah. Sanadihii la soo dhaafay, dahaarka caagga ah ayaa si weyn loogu isticmaalay taleefanka gacanta, TV-ga, kumbuyuutarka, baabuurta, qalabka mootooyinka iyo qaybaha kale, sida qaybaha baabuurta iyo qaybaha gudaha. Qaybaha, dahaarka caagga ah ayaa sidoo kale si weyn loogu isticmaalaa ciyaaraha iyo qalabka firaaqada, baakadaha qurxinta, iyo alaabta lagu ciyaaro.
Cilmiga xasaasiyadda dahaarka acrylate resin, heerkulbeegga acrylate-polyurethane resin beddelka daahan, daahan polyolefin koloriined modified, daahan poliurethane la beddelay iyo noocyo kale, oo ka mid ah daahan acrylic ayaa ah kuwa ugu isticmaalka badan. Tan iyo goobaha codsiga ee daahan caag ah inta badan waa-teknoolojiyad sare iyo wax soo saarka-qiimaha-sare ah, wax soo saarka badan oo tignoolajiyada sare ee warshadaha daahan ayaa sidoo kale si joogto ah loo isticmaalo daahan caag ah, sida Floppy. midabka dahaarka, dahaarka pearlescent, dhoobada dhoobada, dahaarka smart, Dahaarka functional gaarka ah, iwm.
Shuruudaha suuqyadan dalabka ah ee daboolka caagga ah iyo tayada caagadaha loo isticmaalo ayaa go'aaminaya jihada horumarinta ee daboolka caagga ah. Tusaale ahaan, dahaarka caagga ah ee telefoonnada gacanta ayaa u baahan metallic midabka, adkaanta sare iyo shucaaca mowjadaha anti-electromagnetic; Qaybaha caaga ah ee loogu talagalay gudaha baabuurta waxay u baahan yihiin xeelad sare, iwm; dahaarka caaga ah ee alaabta lagu ciyaaro waa inay ahaadaan kuwo aan sun ahayn, muuqaal cusub, oo ay ka buuxaan dhadhanka waqtiyada.
Rinjiga Polyethylene ee Shiinaha wuxuu bilaabmay horaantii 1980-yadii. Iyada oo horumarka degdega ah ee warshadaha wax soo saarka caagga ah, horumarka horumarinta ee daahan caag ah ayaa degdeg ah, gaar ahaan warshadaha baabuurta, qalabka guriga iyo beeraha kale. Sannadkii 2007-dii, dalkaygu waxa uu u baahday wax-soo-saarka caaggu waxa uu gaadhay 35 milyan oo tan, isticmaalka daaha caagga ah ee la isticmaalayna waxa uu dhaaftay 120,000 oo tan, iyada oo celcelis ahaan heerka kobaca sannadlaha ahi yahay 10%-15%. Isticmaalka dahaarka caagga ah ee dalkaygu wuxuu ku jiraa safka hore ee warshadaha dahaarka, isticmaalkeeduna wuxuu darajeeyaa kaliya ka dib naqshadeyntaral dahaarka, dahaarka baabuurta, daahan ka-hortagga daxalka iyo daahan alwaax, iyo rajada suuqa waa rajo.
