Makapu epurasitikichinhu chakajairika muhupenyu hwedu, tinowanzo kushandisa makapu epurasitiki kuzadza mvura kana zvinwiwa.Kune marudzi akawanda emakapu epurasitiki, mamwe makapu epurasitiki anogona kuzadzwa nemvura inopisa, asi mamwe makapu epurasitiki anogona kuzadzwa nemvura inotonhora chete.Panguva imwecheteyo, zvinhu zvakasiyana-siyana zvichavewo zvakasiyana pakuonekwa.Hupenyu hwatinoshandisa makapu epurasitiki anowanzo kugadzirwa nePP uye PET zvinhu, vanhu vazhinji vachange vari pamukombe wepurasitiki ndeye PP zvinhu kana PET zvinhu zvakanaka kune iri dambudziko unonzwa uchinetseka?Nokuda kwechinetso ichi, zvinotevera zviduku zvekugadzira kuti zvipindure iwe, shamwari dzinofarira dzichakurumidza kuuya pamwe chete kuti dzione!
PP i polypropylene, PET ipolyester.Zvinofungidzirwa kuti ese ari maviri haana chepfu, asi maererano nekuramba kuchembera uye kuramba kwemamiriro ekunze, PP inonyanya kukodzera makapu emvura, PP ine yakanaka yekupisa inodzivirira, inogona kumira kutonhora kwakanyanya kwe120 degrees, ndiyo chete zvinhu zvepurasitiki zvinogona kuiswa mukati. microwave.
Polypropylene (PP) zvikumbiro: microwave ndiro, mapoto, mabhakiti epurasitiki, thermos shells, mabhegi akarukwa, nezvimwewo .. Hunhu: kugadzikana kwemakemikari, kushanda kwehutano hwakanaka, kupisa kwakanyanya.Microwave tableware inogona kushandiswa yakamaka PP epurasitiki zvigadzirwa.Toxicity: isiri-chepfu, isingakuvadzi kumuviri wemunhu.Iyo polymer inogona kuve neatatu-dimensional chimiro: isometric, intergraphic, atactic polypropylene, maviri ekutanga anogona kupenya, ekupedzisira haagone.Zvigadzirwa zvepolypropylene zvinowanikwa mukutengesa ndizvo chaizvo chimiro chemusika iso-gauge, nzvimbo yekunyungudika ye164 ~ 170 madhigirii Celsius, iyo crystalline chikamu chehuremu hwe0.935 gramu / cubic centimita, iyo isina kuchena chikamu che0.851 gramu / cubic centimita.PP's hombe drawback ndeyekuti iri nyore kuita oxidize uye zera.Iye zvino nekuwedzera kwe antioxidants uye ultraviolet absorbers kukunda.
Polyester (PET) zvikumbiro: mabhodhoro ezvinwiwa epurasitiki, mabhodhoro emishonga, mabhodhoro ekuzora, mabhodhoro emafuta, uye akasiyana mabhodhoro mavharo, chivharo chekuvhara.Hunhu: kujeka kwakanaka, kusiri nyore kuputsika, kugadzikana kwakanaka kwekemikari, kwakakodzera kwakasiyana-siyana yemvura kana yakasimba zvinodhaka packaging.Iine kudzivirirwa kwakanaka kune ultraviolet mwaranzi.Toxicity: isiri-chepfu.
PET bhodhoro repurasitiki ndiyo inonyanya kushandiswa kwechinwiwa kurongedza.Nzvimbo yepamusoro muChina yekutakurisa zvinwiwa indasitiri inofanirwa kunge iri PET mabhodhoro epurasitiki, kusvika parizvino, hapana chepamusoro kana zvirinani zvepasuru zvakawanikwa kutsiva PET mabhodhoro epurasitiki. muchina wekuumba mukuumbwa kwemabhodhoro ePP ane zvakanakira pachena, yakasimba, isingapise kupisa, uye mutengo zvakare wakadzikira.
PP mabhodhoro epurasitiki ane zviri nani kupisa kupisa, bhodhoro chimiro chinoratidza kunzwa, kuchengetedzeka, hutsanana uye zviri mukati mekuravira kwekuchengetedza kushomeka, mutengo wakachipa kupfuura PET, PS, PE nezvimwe zvinhu.PP mabhodhoro epurasitiki mumusika wekutakurisa zvinwiwa. mukushandiswa kwechiyero kwave kuswedera zvishoma nezvishoma kusvika mabhodhoro ePET, akagadziridzwa resin, permeability ekuwedzera, uye michina nehunyanzvi hunyanzvi nguva nenguva kuita kusimudzira kwemidziyo yePP kunogona kutsiva girazi, PET nemidziyo yePVC, chikamu chemusika chiri kukura.
.
PP uye PET zvinhu zvine zvazvakanakira uye maitiro, hapana mhedziso yakanaka kana yakaipa, zvinonyanya zvinoenderana nezvido zvemunhu uye kushandiswa kwemamiriro ezvinhu kusarudza, kana ichiwanzo shandiswa pakudziya kwakanyanya, unogona kusarudza PP zvinhu.Zviri pamusoro apa kuongororwa kwePPmakapu epurasitikiuye PET epurasitiki makapu, ndinovimba inogona kukubatsira.
