Kushandiswa kwefirimu renylon mukurongedza chikafu chemhuka

Munyika dzekumadokero, "pet economy" iindasitiri hombe.Kutora chikafu chemhuka semuenzaniso, North America (kunyanya United States) ndiyo musika mukuru wevatengi wezvese zvekudya zvezvipfuyo, uye inoverengera kuwanda kwekutengesa.Western Europe ndiyo inotungamira musika wevatengi kune ese mamwe mapoka echikafu chemhuka, uye yechipiri yakakura musika wevatengi wembwa nekatsi chikafu.Pakati pavo, kuvandudzwa kwehupfumi hwemhuka muUnited States neJapan inonyanya kuzivikanwa.

Zvinetso zvinowanzoitika mumamiriro ezvinhu emusika

MuChina, vanhu vakawanda vane mhuka dzinovaraidza.Nekuwedzera kwehuwandu hwezvipfuyo, nhevedzano yemaindasitiri ane hukama akabuda akatenderedza hupfumi hwezvipfuyo, senge chikafu chezvipfuyo, zvekushandisa, kurapwa kwezvipfuyo, indasitiri yerunako rwezvipfuyo, nezvimwe, izvo zvichava nemusika wakakura tarisiro.Kurongedza chikafu chemhuka inova imwe yenzvimbo dzinopisa mumunda wekurongedza mune ramangwana.

Kutora chikafu chemhuka senge katsi nembwa semuenzaniso, zvigadzirwa zvinonyanya kugadzirwa nyama.

Hunhu hwayo hunosanganisira zvinhu zviviri zvinotevera:

1. Kuti uchengetedze kuravira kwechikafu chemhuka, izvo zvinongedzo hazvifanirwe kuitwa zvakanyanya kupfava kana upfu panguva yekugadzira.Izvo zvinodiwa kuchengetedza kuoma uye brittleness yenyama, mapfupa uye hove mapfupa.Naizvozvo, chikafu chemhuka chinoratidzwa nechimiro chisina kujairika uye chine zvinhu zvakapinza semapfupa nehove mapfupa.

2. Chikafu chemhuka chikafu chine irradiated.Kuti uwedzere hupenyu hwesherufu, chikafu chemhuka chinoda kugezwa kuti chiuraye.Chikafu chine irradiated chinoreva chikafu chinogadzirwa neradiation ine gamma rays inogadzirwa necobalt-60 uye cesium-137 kana maerekitironi matanda ari pazasi 10MeV anogadzirwa nema electron accelerators, zvinosanganisira chikafu chine irradied chikafu uye zvigadzirwa zvapera.

Parizvino, tekinoroji yeradiation inoshandiswa zvakanyanya munyika dzakawanda kuve nechokwadi chekuchengetedzwa kwechikafu uye kuwedzera hupenyu hwesherufu yekudya, uye inocherechedzwa nevatengi vakawanda.Kufanana nefiriji yepasi-tembiricha, kurapa kwakanyanya uye kurapwa kwemakemikari, tekinoroji iyi inogona kubvisa tupukanana. izvo zvinokonzeresa huwori hwechikafu uye zvirwere zvinotakura chikafu mukudya.Mukurongedza chikafu, mwaranzi inzira yakanaka yekuwedzera hupenyu hwesherufu yekudya.

Mune aseptic kurongedza masisitimu, nzira dzesterilization dzekurongedza zvinhu dzinosanganisira ultraviolet sterilization, makemikari nzira uye ultraviolet yakasanganiswa sterilization, infrared sterilization, ionizing radiation uye mwenje pulses.Kana chinhu chekurongedza chisingakwanisi kupfuura simba rekupisa kana kupfuura neIonizing mwaranzi inzira yakanaka inotonhora yekuvharisa kemikari disinfection uye sterilization.

Parizvino, iyo yakajairwa pet kurongedza mumusika weChinese kazhinji inotora nzira yekurongedza ye zipper matatu-dimensional bag.Kuti uvandudze sherufu mhedzisiro uye zvipingamupinyi mashandiro, mazhinji epamba anochinjika ekurongedza anogadzira anoshandisa VMPET kana AL sechivharo layer;

Matambudziko ekurongedza chikafu chemhuka muChina anosanganisira zvinotevera zvinhu:

1. VMPET kana Al inoshandiswa sechivharo chevhavha, asi zvigadzirwa hazvigone kuonekwa zvakananga, izvo zvinogadzirisa masherufu ekuratidza maitiro ezvigadzirwa;

2 Sezvo zvigadzirwa zviri mapfupa, mapfupa ehove uye zvimwe zvinhu, bhegi iri nyore kubaya, zvichikonzera matambudziko emhando.

3 Kutsvedzerera kwebhegi rekurongedza hakuna kunaka, uye kuvhura kwakashata mukugadzira, uye kugona kwekugadzira kwakadzikira.Panguva imwecheteyo, ichaderedzawo chiyero chekushandiswa kwebhegi rekurongedza uye kuwedzera mutengo.

4 Mushure mekuvhenekera, iyo yese mechanical properties yebhegi yakadzikira.

Dhizaini zano remubatanidzwa chimiro chekurongedza chikafu chemhuka

Mukugadzirwa chaiko, irradiation haina mhedzisiro pane zvimiro zvegirazi uye simbi midziyo, asi inogona kuderedza kuchinjika uye mechaniki zvinhu zvepurasitiki.Nokudaro, mukugadzirisa kwekugadzirisa, kana pasina chimiro chakakodzera chekubatanidza, bhegi iri nyore kuputirwa uye maitiro emuviri uye emagetsi ebhegi anoderedzwa.Naizvozvo, zvakakosha zvikuru kudzidza iyo yakasarudzika inoumbwa chimiro kuti ienderane nemhedzisiro yeradiation pazvinhu zvepurasitiki.

Kurongedza chikafu chemhuka kunofanirwa kuzadzisa zvinotevera zvinodiwa panguva yekurongedza, chekufambisa, kuchengetedza uye kushandisa:

1. Kushanda zvakanaka kwemhinganidzo

Zvigadzirwa zvepasuru chikafu chezvipfuyo, izvo zvinofanirwa kukwanisa kuzadzisa zvinodiwa zvemhando yezvigadzirwa, kuchengetedza kunaka uye kunaka kwezvigadzirwa, uye kuve nehupenyu hwakanaka hwesherufu.

2. Good puncture kuramba

Ine zvinhu zvinopinza zvakaita semapfupa nehove.Kuti uve nechokwadi chekuti bhegi harina kuputika, rinofanira kunge riine puncture resistance.

3. Kuonekwa kwakanaka

Iwe unogona kuona zvakananga zvigadzirwa kubva pasuru kukwezva kutarisa kwevatengi.

4. Kuomarara kwakanaka

Rudzi urwu rwechikafu chemhuka dzakarongedzerwa neakamira zipper tepi, saka iyo yekurongedza ine kuoma kwakanaka uye inogona kuvandudza sherufu mhedzisiro yezvinhu.

5. Good radiation resistance

Mushure meirradiation, inogona kuramba ichichengetedza yakanaka mechanical properties.

Muenzaniso wekusarudza chimiro

Kuti tisangane nezviri pamusoro zvinodikanwa zvekurongedza chikafu chemhuka, isu tinokurudzira kuti inotevera inoumbwa chimiro inogona kugamuchirwa:

Pakati pepakati: BOPA firimu kana EHA yakakwira barriers firimu ine yakakwira oksijeni kuramba

BOPA nylon is polyamide, ine simba rakanakisa, kusimba, kusimba, kurebesa uye kupfeka kuramba.Nylon inosarudzwa nekuti ine yakanaka yemuviri uye yemagetsi zvinhu.Mushure mekubatanidza, inogona kuwedzera kupikisa kwepuncture, kupikisa kwemaitiro uye zvimwe zvinhu zvechigadzirwa, uye inogona kuchengetedza zviri mukati zvakanaka.Kurudziro: Changsu BOPA Ultrany.

EHA ine Ultra-yakakwira okisijeni kuramba (oxygen transmittance OTR yakaderera se2cc/ ㎡ zuva · ATM), iyo inogona kuwana yakanakisa kunhuhwirira kuchengetedza;Kuramba kwayo kwekukwesha, kusimba kuramba uye kusimba kwekuteerera kwakanyanya kuderedza chiyero chekutyoka kwebhegi;Uye inogona kuwana kujeka kwepamusoro uye yakanakisa kudhinda maitiro;Mukuwedzera, ihwowo hushamwari hwezvakatipoteredza husingazobudisi magasi ane chepfu kana apiswa.Kurudziro: Changsu Supamid EHA nyowani yekukiya firimu.

Inner layer: PE firimu rine yakagadziridzwa formula

Tichifunga nezve kuchengetedzeka uye hutsanana hwechikafu chemhuka, chigadzirwa ichi chinotora nzira yekugadzira-isina solvent.Nekudaro, iyo inonyungudutsa-yemahara yekugadzira maitiro ichava nematambudziko eiyo yakanyanya kukweshera coefficient uye kushomeka kuvhurika.Naizvozvo, kuitira kuti uvandudze kuchinjika kwemidziyo yePE, kuumbwa, kupikisa kuramba uye neradiation kuramba kwebhegi muviri kunofanirwawo kutariswa.Iyo PE fomula inogona kuvandudzwa kuti iite zvirinani kuchinjika kwemidziyo, kuomarara uye kupuncture kuramba.

BOPA nylon is polyamide, ine yakasimba crystallinity, yakakwirira kunyungudika uye kuita kwakanakisa.Kuomarara kwakanaka, kusimba kwesimba uye simba rekuita zviri nani pane zvakajairika firimu repurasitiki.Sechikamu chepakati mupurojekiti iyi, inogona kuvandudza kuramba kwePET kurongedza kudzivirira zvinhu zvakapinza semapfupa ehove kubva pakubaya firimu.Uyezve, kusimba kwemhepo yenylon kuri nani pane iyo yePE nePP, iyo inogona kuvandudza iyo inovharira kuita kwekurongedza.Panguva imwecheteyo, ine yakanaka yekupikisa mafuta, ayo anogona kushingirira kusviba kwemafuta kana kurongedza chikafu chemhuka chezvigadzirwa zvenyama, kuitira kudzivirira delamination yekurongedza firimu uye kuderera kwesimba re peel.
