Munzvimbo ine simba yekurongedza chikafu, uko kuchengetedzeka, kuwedzera nguva yekushanda, uye kuvimbika kwechigadzirwa zvinosangana, zvinhu zvinosimbisa mvura zvakabuda semagamba asina kurumbidzwa. Izvi zvinowedzerwa, zvakagadzirwa zvakanaka kuti zvishandiswe mumafirimu emhando yepamusoro, zvinoita mabasa akawanda akakosha pahutano hwevatengi uye kushanda zvakanaka kwemaindasitiri. Ngationgororei mabasa mana makuru anoita kuti zvinhu zvinosimbisa mvura zvive zvakakosha mumapakeji echikafu emazuva ano.
Kutsungirira Kupisa: Mafirimu Anodzivirira Kubva PakupiswaKuora kwehunhu
Mafirimu emhando yechikafu, angave epolyethylene (PE) kana epolypropylene (PP), anogadziriswa nekupisa kwakanyanya (semuenzaniso, extrusion, blow molding) kusvika ku230°C.Zvinosimbisa mvurainoshanda sevarindi vekupisa, ichidzivirira ma free radicals anokonzerwa nekupisa. Ongororo yakaitwa neInstitute of Packaging Technologies yakawana kuti pasina ma stabilizers, sampuro dzemafirimu dzakaratidza kudzikira kwe35% musimba rekudhonza mushure memaminitsi gumi pa200°C. Kusiyana neizvi,mafirimu ane optimized liquid stabilizerMishonga iyi inochengetedza simba rayo repakutanga rinodarika 90%, zvichiita kuti chimiro chayo chive chakasimba panguva yekubika senge matireyi ekubikisa anoiswa mu microwave.
Kurebesa Hupenyu Hwesherufu: Kuderedza Kuoxidation uye Kuora kweUV
Kunze kwekugadzirisa, zvinosimbisa mvura zvinorwisa zvinokanganisa nharaunda panguva yekuchengetera nekutakura. Mwaranzi yeUV uye kusvibiswa kweokisijeni zvinogona kukonzera photo-oxidation, zvichiita kuti mafirimu ave yero uye aite seanopwanyika. Semuenzaniso, mukuyedza kwekuenzanisa pakuisa mbatata chip, mafirimu ane UV-stabilizing liquid additives anowedzera kutsva kwechigadzirwa ne25%, sekuyerwa kweperoxide. Ma antioxidants ane fatty acid ari muzvisimbisa mvura anobvisa okisijeni, nepo UV absorbers senge benzotriazoles inodzivirira mafirimu kubva mukukuvadzwa nemwaranzi, ichichengetedza runako rwepakeji uye kukosha kwekudya kwechikafu.
KugadziriswaKuvandudza: Kugadzirisa Kuyerera Kwemvura uyeKufanana
Vagadziri vanosangana nematambudziko ekuwana ukobvu hwakaenzana hwefirimu uye kupera kwepamusoro. Zvigadziriso zvemvura zvinoderedza kunyungudika kwekunyungudika nekusvika 18%, zvichienderana nemishumo yeindasitiri, zvichiita kuti kubuda kwakapfava kubude. Kuvandudzwa uku kwakakosha zvikuru pamitsetse yekugadzira inomhanyisa, uko kusiyana kweukobvu hwe 0.1 mm kunogona kutungamira mukurasa kwakawanda. Nekukurudzira purasitiki inogara iripo, zvinogadzirisa zvinoderedza zvikanganiso zvakaita sekuchinja-chinja kweganda resharkskin nehukobvu, zvichikonzera kuchengetedza mari uye kuwedzera kugadzirwa.
Kutevedzera Mutemo: Kuve nechokwadi chekuti Kuchengetedzwa Kwechikafu uye Kuchengetedzwa KwemutengiKuvimba
Kuchengetedzeka kwemafirimu emhando yepamusoro yechikafu kunoenderana nekudzora kufambiswa kwemafuta. Zvinosimbisa mvura zvinofanirwa kutevedzera mitemo yakaoma, yakaita seUS FDA 21 CFR 178.2010 uye EU Regulation (EC) No 10/2011. Semuenzaniso,zvinosimbisa calcium-zinc, dzakasimbiswa sedzisina chepfu dzimwe nzira dzechinyakare dzinobva mu lead, dzinotevedzera mitemo yepasi rose yekubata chikafu. Mwero wadzo wakaderera wekufamba (≤0.1 ppm yesimbi dzinorema) dzinoita kuti dzive dzakakodzera kurongedza chikafu chevana, uko kuchengetedzeka kwakanyanya.
Mamiriro Emangwana: Kuvandudzwa muTekinoroji Yekusimbisa Simba
Indasitiri iyi iri kuona shanduko ichienda kune zvinosimbisa mvura zvakagadzirwa ne bio-based liquid stabilizers. Oiri yesoya yakasanganiswa ne epoxidized, inobva muzvinhu zvinogona kushandiswazve, ikozvino inoumba 30% yemusika we stabilizer inochengetedza nharaunda. Vatsvaguriri vari kutsvagawo maformula ane mabasa akawanda anosanganisa kugadzikana nezvinhu zvinoshanda, zvakaita se antimicrobial ability. Kufambira mberi uku kunovimbisa kutsanangura patsva kuchengetedzeka uye kuchengetedzeka kwemapakeji ezvekudya.
Mukupedzisa, zvinosimbisa mvura hazvisi zvekungowedzera chete asi zvinhu zvakakosha zvinochengetedza kunaka kwechikafu, zvinoita kuti kugadzirwa kuve nyore, uye zvinotsigira kutevedzera mitemo. Sezvo kudiwa kwemutengi kwekurongedza kwakachengeteka uye kwenguva refu kuchikura, mishonga iyi inoramba ichichinja-chinja, ichitungamira hunyanzvi muhurongwa hwekurongedza chikafu.
