Sechinyorwa chekudhinda, yemafirimu epurasitiki emabhegi ekudya ane mabhegi ane pfupi nhoroondo. Izvo zvine zvakanakira kureruka, kupokana, unyoro, kupokana kweokisiokisi, kuomarara uye kupeta kupokana, nekudzivirirwa, uye kuchengetedzwa kwezvinhu, uye zvinogona kubereka chimiro chechigadzirwa. uye ruvara. Nekuvandudzwa kweindasitiri petrochemical, pane akawanda uye akawanda marudzi epurasitiki mafirimu. Kazhinji inoshandiswa mafirimu epurasitiki ari polythylene (pe), polyester aluminized film (vmmmet), polyester film (pet), polypropylene (pp), nylon, etc.
Zvivakwa zveMafirimu epurasitiki akasiyana siyana akasiyana, kuoma kwekudhinda zvakare kwakasiyana, uye zvinoshandiswa seyakagadzirwa zvinhu zvakare zvakasiyana zvakare zvakasiyana.
Firimu rePolyethylene risina ruvara, risingarambiki, dzinosiririsa, translucent isiri-ine chepfu anodzivirira insulation zvinhu, iyo inoshandiswa zvakanyanya muhomwe kugadzira. Icho chinhu chinonyanya kuoma, saka zvakawedzera kudhinda uye zvinofanirwa kuongororwa kudhinda zviri nani.
Yakasarudzika firimu ine zvese hunhu hwepurasitiki firimu uye hunhu hwesimbi. Kumusoro kwefirimu kunounganidzwa nealuminium kuti udzivirire kubva pachiedza uye uv radiation, izvo zvisingagumi zvinowedzera mararamiro ezvinyorwa, asi zvakare zvinowedzera kupenya kwefirimu. Inotsiva aluminium foil kune imwe nhanho, uye ine zvakanakira mutengo wakaderera, kutaridzika kwakanaka uye kwakanaka zvinotyisa zvivakwa. Mafirimu akasvinwa anoshandiswa zvakanyanya mukurongedza kwemari. Iyo inonyanya kushandiswa mukuiswa kwezvinhu zvakaoma uye zvinodhaka zvakadai semabhisiketi, uye kurongedza kwekunze kwemimwe mishonga uye cosmetics.
Iyo polyester firimu isina ruvara uye yakajeka, inonyorova, mhepo-yakasimba, yakapfava, yakanyanya-simba, inodzivirira acid, oiri uye isingagarike yekudziya yakakwirira uye yakaderera. Mushure meEdm kurapwa, ine yakanaka nzvimbo yekukurumidza kuink. Zvekutakura uye zvigadzirwa zvemukati.
Polypropylene firimu rine gloss uye transpency, kupisa kupokana, acid uye alkali kuramba, soly kuramba, kubvarura, kubvarura gasi rekuparadza kwegesi. Haigoni kupisa chakasungwa pazasi 160 ° C.
Nylon firimu yakasimba kupfuura polyethylene firimu, isina kunaka, isina-chepfu, uye kushaika mabhakitiriya, mafuta, esters, mvura inovira uye yakawanda sol. Iyo inowanzoshandiswa kutakura-kutakura, abrasion-inodzivisa kurongedza uye kurongedza kurongedza (chikafu chekudzosera) uye chinobvumira kudhinda pasina kurapwa pasina kurapwa.
Nzira dzekudhinda dzemafirimu epurasitiki inosanganisira kudhinda kwekudhinda, kudhinda kwekudhinda uye kudhinda skrini. Kudhinda Inks kunoda kwazvo viscosity uye yakasimba kudenha, saka iyo ink mamorekuru inonamira kune iyo nzvimbo yakaoma yepurasitiki uye inoparadzaniswa nyore nyore kubva kune iyo okisijeni mumhepo kuti iome. Muzhinji, Ink yefirimu yepurasitiki yekudhinda yekudhinda inoumbwa inoenderana neyekutanga ambures ine doro zvine hungwaru, uye kuumbwa kwechidimbu Iyo ine hunhu hwekudhinda kwakanaka kwekudhinda, kusimba kwakasimba, ruvara rwakajeka uye nekukurumidza kuoma. Yakakodzera kudhinda nejira rekudhinda prinji.
Ndinovimba ichi chinyorwa chinogona kukubatsira uye kukuzivisa iwe zvakawanda nezve kurongedza.
