Mafirimu akasiyana siyana anowanzoshandiswa muhupenyu hwezuva nezuva. Ndezvipi zvinhu zvinogadzirwa mafirimu aya akagadzirwa? Ndeapi maitiro emari yeumwe neumwe? Izvi zvinotevera chidimbu chakatsanangurwa kune mafirimu epurasitiki zvinowanzoshandiswa muhupenyu hwezuva nezuva:
Firimu repurasitiki ifirimu rakagadzirwa nePolyvinyl chloride, polythylene, polystyrene uye mamwe enzvimbo, anowanzoshandiswa pakutakura, kuvaka, uye seyakawirirana, nezvimwe.
Firimu yepurasitiki inogona kukamurwa mukati
-Industrial firimu: Blown Firimu, Calendered firimu, yakatambanudzwa firimu, yakakandwa firimu, nezvimwe.;
-Kurima sodhi yefirimu, mulch firimu, nezvimwewo.;
-Films yekukanda (kusanganisira composite mafirimu emishonga yemishonga, mafirimu emapikicha ekudya kwekudya, nezvimwewo).
Zvakanakira uye zvakashata zvepurasitiki firimu:
Maitiro ezviitiko zvemapurasitiki epurasitiki:
Biaxally yakatumidzwa polypropylene firimu (bopp)
Polypropylene ari Thermoplastic resin inogadzirwa nePolymerization yePropeylene. Copolymer PP Zvigadzirwa Zvekudziya Kukanganisa Kupisa (100 ° C), yakaderera transcarency, yakaderera simba, uye simba rekukanganisa kwePP inowedzera nekuwedzera kwezvinhu zvetsika. Iyo Vicat zvinyoro nyoro tembiricha yePP ndeye 150 ° C. Nekuda kweiyo yakakwirira mwero wekrisimita, izvi zvinyorwa zvine yakanaka kwazvo yekuomarara uye kukwenya kupokana zvivakwa. PP haina kunetsana kwezvakatipoteredza kupaza matambudziko.
Biaxally yakatenderwa polypropylene firimu (Bopp) ndeyekuchinja-chinja inoxix pairating zvinhu zvakavandudzwa muma1960s. Inoshandisa mutsara unokosha wekugadzira kusanganisa Polypropylene mbazyi uye zvinowedzera zvekuwedzera, chinyungudike uye nekuvanyunguzira mashiti, uye wozovatambanudzira mumafirimu. Inoshandiswa zvakanyanya muchikamu chekudya, pipi, fodya, tii, muto, mukaka, manyoro, etc., uye ane mukurumbira we "kurongedza mambokadzi". Uye zvakare, inogona kuiswawo pakugadzirira kweiyo kukosha-kwakakura zvigadzirwa zvakaita seMagetsi membranes uye microupus membudzi, saka tarisiro yekuvandudza yebopp mafirimu akafara kwazvo.
Bopp firimu haingove nezvakanakira density yakaderera, yakanaka kupesana uye yakanaka kupisa kupokana kwePP resin, asi zvakare ine masimba akanaka emidziyo uye yakakwira masimba uye zvakapfuma masimba emidziyo yezvinhu zvisina kugadzirwa. Bopp firimu inogona kusanganiswa nezvimwe zvinhu zvine zvakakosha zvivakwa kuti uwedzere kuvandudza kana kugadzirisa basa. Zvigadzirwa zvinowanzoshandiswa zvinosanganisira pefirimu, masimba polypropylene (CPP) firimu, polyvinylidene chloride (PVDC), Aluminium firimu, nezvimwe.
Low density polyethylene firimu (ldc)
Polyethyle firimu, zvinoreva kuti pe, ine hunhu hwekunyorovesa kuramba uye kuderera kunyengedzwa.
Low-DenSity Polyethyle (LPDE) iri Resin Synthetic yakawanikwa neTheylene Railcal Pollmerization pasi pekumanikidzwa kwepamusoro, saka inonziwo "yakakwirira-kumanikidza polyethyle". LPDE itsvuzi mbozha nemapazi ehurefu hwakasiyana pajasi rakakura, negumi nemashanu kusvika makumi matatu eTefyl, butyl matavi emakaroni emakaroni mune iyo maatomu makuru. Nekuti cheni yematehwe ine marefu marefu uye ipfupi denderedzwa maketani, chigadzirwa chine simba rakaderera, kudzikisira kwemakemikari, kunze kwekunetseka kwezvinhu zvakanaka, Translucent uye Glossy Stability Setability, kupisa kupisa, kupokana nemvura uye kuramba kununurwa, kuramba kurwisa, uye kunogona kubikwa. Kwayo chikuru kusagadzikana ndeyezvakaipa zvaro zvipingamupinyi kuokisijeni.
Izvo zvinowanzoshandiswa seyenguva yemukati yeyakajaira inoshanduka-shanduka ekugadzira zvinhu, uye zvakare inoshandiswa zvakanyanya uye yakashandiswa mapepa ekuputika, accounting kweanopfuura makumi mana muzana ekushandiswa kwemafirimu epurasitiki. Kune marudzi mazhinji emhando dzePolyethyle pafirimu, uye zviitiko zvavo zvakasiyanawo. Iko kuita kweiyo imwe-layer firimu haina kuroora, uye kuita kweiyo composite firimu inoenderana. Icho chinhu chikuru chekudya kwekudya. Kechipiri, firimu rePolyethyley rinoshandiswawo mumunda wehurumende yehurumende, senge geomembrane. Inoita seyakawirwa yemvura mune yehurumende engineering uye ine kuderera kwakanyanya. Mafirimu ekurima anoshandiswa mukurima, izvo zvinogona kukamurwa mufirimu remufirimu, mulch firimu, girini yekuvhara firimu, girini rekuchengetedza firimu uye zvichingodaro.
Polyester firimu (pet)
Polyester firimu (pet), inowanzozivikanwa sePolyethylene Terephthalate, itshandu yeinjiniya yeinjiniya. Icho chinhu chemafirimu chakagadzirwa nemashiripiti akakora nekuwedzera uye ipapo biaxally yakatambanudzwa. Polyester firimu inoonekwa neakanakisa manhamba, zvakanyanya kuomarara, kuomarara, kupokana nekupokana, kupinza kwemakemikari, kupokana kwemakemikari, kurwisa kwemafuta, kurwisa kwemhepo uye kunhuhwirira kwemhepo uye kunhuhwirira kwemhepo. Imwe yeiyo isingagumi inoumbwa firimu substrates, asi iyo Corona Resistance haina kunaka.
Mutengo wemutengo wePolyester firimu yakakwirira, uye gobvu rayo kazhinji 0.12 mm. Iyo inowanzoshandiswa seyekunze zvinyorwa zvekudya zvekudya zvekutakura, uye kune kudhinda kwakanaka. Uye zvakare, polyester firimu inowanzoshandiswa sekudhinda uye kurongedza mapopoma zvakadai seyunivhesiti yekudzivirira firimu, uye yakashandiswa nemakati muindasitiri sibheri
Nylon epurasitiki firimu (Ony)
Zita remakemikari raNylon huri polyamide (PA). Parizvino, kune marudzi mazhinji eNylon awedzeredzwa, uye marudzi makuru anoshandiswa kugadzira mafirimu ane tron 6, NYLON 66, NYLONI FLIONS Simba, uye kupokana kwakanyanya, kupokana nekudziya, kuramba kwemafuta uye kurwisa kwemafuta uye organic solvent kuramba. Kunaka kupfeka kurwisa uye kupunzika kupokana, zvakanyanyisa okisijeni, asi zvakanyanyisa kupfeka, zvakakura zvekupfeka, chikafu chakarongeka, chikafu chakarongedzwa, chakarongedzwa, chakarongedzwa chikafu, chikafu chakabiwa, nezvimwewo.
Cast polypropylene firimu (cpp)
Kusiyana neBiaxally yakatumidzwa polypropylene firimu (Bopp) maitiro, iyo cast polypropylene firimu (cpp) yakatambanudzwa, isina-yakatarisana-yakatsanangurwa firimu inogadzirwa neyakagadziriswa nekunyungudika. Iyo inoratidzwa nekukurumidza kugadzirwa kumhanya, kukwidziridzwa kwepamhepo, yakanaka firimu transpency, gloss, yakajeka kusaenzana, uye chiyero chakanakisa chezvivakwa zvakasiyana siyana. Nekuti iyo yakarongedzwa flat yakagadziriswa firimu, tevera-tevera basa sekudhinda uye kugutsikana kwakanyanya nyore. CPP inowanzoshandiswa zvakanyanya mumatanho ekutakura, maruva, chikafu, uye zvinodiwa zvezuva nezuva.
Aluminium-akanyura plastiki firimu
Iyo aluminized firimu ine zvese hunhu hwepurasitiki firimu uye hunhu hwesimbi. Basa reAluminium rakareruka pamusoro pefirimu ndeyekudzivirira kweiyo firimu uye kudzivirira ultraviolet radiation, izvo zvisingori zvinongowedzera hupenyu hwesheruzvidzo, asi zvinovandudza kupenya kwefirimu. Naizvozvo, firimu rakavhurwa rinoshandiswa zvakanyanya mumakombhasi pakurongedza, inonyanya kushandiswa mune yakaoma uye yakazvishongedza chikafu chakadai semabhisiketi emamwe mishonga nemimwe mishonga uye cosmetics.
