Mabhegi ekurongedza chikafundecheimwe yezvikafu zvekurongedza zvinhu zvekuyedza mapoka, anonyanya kugadzirwa epurasitiki zvinhu, senge polyethylene ekurongedza mabhegi, polypropylene mabhegi ekurongedza, polyester mabhegi ekurongedza, polyamide ekurongedza mabhegi, polyvinylidene chloride ekurongedza mabhegi, polycarbonate yekurongedza mabhegi, polyvinyl mabhegi edoro uye mamwe mabhegi. mabhegi matsva epolymer ekurongedza.
Zvinonyatsozivikanwa kuti zvimwe zvinhu zvine muchetura uye zvinokuvadza zvinogona kugadzirwa panguva yekubereka uye kugadzirisa zvigadzirwa zvepurasitiki, saka kuongororwa kwemhando yemabhegi ekurongedza echikafu kunosanganisira kuongororwa kwehutsanana kwave chinhu chakakosha chekudzora hunhu.
1.Test overview
Nekuda kweizvozvochikafu chekuisa bhegiinosangana zvakananga nechikafu chatinodya zuva nezuva, chiyero chekutanga chekuongorora kwayo ndechekuti ine hutsanana.
Kusanganisira evaporation residue (acetic acid, ethanol, n-hexane), potassium permanganate kushandiswa, zvinorema simbi, uye decolorization bvunzo.Evaporation zvakasara zvinoratidza mukana wekutimabhegi ekurongedza chikafuichaita kuti zvisaririra uye simbi inorema kana vasangana nevhiniga, waini, mafuta uye zvimwe zvinwiwa panguva yekushandisa.Zvisaririra nesimbi inorema zvichave nemhedzisiro yakaipa pahutano hwevanhu.Mukuwedzera, zvakasara zvinokanganisa zvakananga ruvara, kunhuhwirira, kuravira uye humwe hutano hwekudya.
Inspection standard yemabhegi ekurongedza chikafu: zvigadzirwa uye zvinowedzera zvinoshandiswa mumabhegi zvinosangana nezvinodiwa zvemhando yenyika, uye zvichava nechokwadi chekuti hapana chepfu kana kumwe kukuvadza kuchaitwa kumuviri wemunhu.
Degradability bvunzo: iyo yekushatisa mhando yezvigadzirwa inogona kukamurwa kuita photodegradation mhando, biodegradation mhando uye nharaunda yekushatisa mhando.Kana kusvibiswa kwekuita kwakanaka, bhegi richaputsika, kusiyanisa uye kusvibisa pacharo pasi pechiito chekubatana kwechiedza uye microorganisms, uye pakupedzisira kuva marara, ayo achagamuchirwa nemamiriro ekunze, kudzivisa kusvibiswa kwakachena.
2.Kuonekwa kwakabatana
Chekutanga pane zvese, kuiswa chisimbiso kwemabhegi ekurongedza kunofanirwa kuve kwakasimba, kunyanya kunemabhegi ekurongedza chikafuizvo zvinoda kuiswa chisimbiso zvachose.
Chiyero chekuongorora chemabhegi ekurongedza chikafuInofanirawo kuongororwa pakuonekwa: kuonekwa kwemabhegi ekurongedza chikafurichava rakati sandara, risina makwara, makwara, furo, mafuta akatyoka nemaunyana uye chisimbiso chekupisa chichava chakati chechetere uye chisina chisimbiso chenhema.Iyo membrane ichave isina kuputika, pores uye kupatsanurwa kweiyo composite layer.Hapana kusvibiswa kwakadai sekusvibiswa, nyaya dzekunze uye mavara emafuta.
Tsanangudzo yekuongorora: iyo yakatarwa, hupamhi, kureba uye ukobvu kutsauka kuchave mukati meiyo yakatarwa.
Yemuviri uye yemechani pfuma bvunzo: mhando yebhegi yakanaka.Yemuviri uye yemagetsi zvivakwa bvunzo inosanganisira tensile simba uye elongation panguva yekuzorora.Inoratidza kukwanisa kutambanudza kwechigadzirwa panguva yekushandiswa.Kana kukwanisa kutambanudza kwechigadzirwa kwakashata, zviri nyore kuputika uye kukuvadza panguva yekushandiswa.
Q: Ungaziva sei kanamapurasitiki ekurongedzazvingava zvine chepfu uye zvisina utsanana?
A: Kuonekwa nekupisa mabhegi epurasitiki:
Mabhegi epurasitiki asina chepfu ari nyore kupisa.Paunotarisisa, uchaona kuti ruvara rwemurazvo rwakaita yero kumuromo uye cyan pachikamu, uye rinodonha sekenduru rine hwema hweparafini.
Mabhegi epurasitiki ane muchetura haasi nyore kupisa.Vachadzimwa pakarepo mushure mekubva patsime remoto.Kumuromo kune yero uye chikamu chegirini.Mushure mekupisa, ivo vachange vari muchimiro chebrashi.
3.Test zvinhu
Sensory quality: mabubbles, wrinkles, mitsara yemvura nemakore, mitsetse, maziso ehove uye zvidhinha zvakasimba, kuremara kwepamusoro, tsvina, blisters, kuoma, kusaenzana kwekuguma kwechiso chefirimu, kupisa kwekuvhara zvikamu.
Saizi kutsauka: kureba kwebhegi, kutsauka kwehupamhi, kureba kutsauka, chisimbiso uye bhegi kumucheto chinhambwe
Yedza zvinhu zvemuviri uye zvemagetsi zvivakwa: tensile simba, zita rekuti kutsemuka, simba rekupisa, rekurudyi-angle kubvarura mutoro, dart kukanganisa, svuura simba, haze, mvura vapor kutapurirana.
Zvimwe zvinhu: okisijeni barriers performance test, bhegi pressure kuramba bvunzo, bhegi kudonha kuita bvunzo, hutsanana kuita bvunzo nezvimwe.
