Maitiro Ekusarudza Magirovhosi Akakodzera Indasitiri Yezvekudya?

Pakusarudza magirovhosi eindasitiri yechikafu, tanga nekuchengetedza, dziviriro, uye kutevedzera mitemo uku uchienzanisa zviri nyore kushanda uye mutengo. Funga nezvezvinhu zvikuru zvinotevera:

1. Mitemo Yekutanga: Kutevedzera Zvitupa Zvekuchengetedza Kubata Chikafu

Pasinei nesarudzo yezvinhu, magurovhosi anofanira kusangana nezvitupa zvekuchengetedza zvemhando yepamusoro sezvinodiwa zvikuru:

• Zvitupa Zvepasirose Zvinowanikwa: FDA (US Food and Drug Administration), EU 10/2011 (EU Food Contact Materials Regulation), LFGB (German Food Contact Materials Standard), nezvimwewo.

2. Kusarudzwa Kwezvinhu: Kufananidza Kushanda Nekushandisa

Zvinhu zvinozivikanwa mumagirovhosi muindasitiri yechikafu zvinosanganisira nitrile, latex, polyethylene (PE), uye PVC, uye nitrile nePE zviri sarudzo huru. Misiyano mikuru ndeiyi inotevera:

• Magorovhosi eNitrile:

Zvakanakira: Haina latex uye haina njodzi yekurwara nezvirwere; haipindi mafuta, acids, alkalis, uye makemikari anochenesa; haipindi maburi zvakanaka uye inogara kwenguva refu. Yakanakira kubata nyama, chikafu chakakangwa, zvinhu zvakabikwa muhari, kana mamiriro ezvinhu ane zvinhu zvekuchenesa (semuenzaniso, kucheneswa kwekicheni, kugadzira chikafu).

• Magorovhosi ePolyethylene (PE):

Zvakanakira: Mutengo wakaderera, kujeka kwakanyanya, zviri nyore kushandisa kamwe chete; zvakakodzera kusvina chikafu chakaoma kwenguva pfupi (semuenzaniso, kurongedza michero/miriwo, kurongedza chingwa nekukurumidza).

• Magorovhosi eLatex:

Zvakanakira: Inochinjika zvakanaka uye inokodzera kuenderana nemaoko, yakakodzera mabasa chaiwo.

• Magorovhosi ePVC:

Shandisa nekungwarira: Mamwe magirovhosi ePVC ane mapurasitiki (semuenzaniso, maphthalates) angasasvike padanho repamusoro rechikafu. Haanawo simba rekudzivirira kupisa uye anogona kuburitsa zvinhu zvinokuvadza pakupisa kwakanyanya. Hazvikurudzirwi sesarudzo inosarudzwa.

3. Kushanda Kwekudzivirira: Kwakagadzirirwa Zvinodiwa Pakushanda

• Kuramba Kuboorwa: Paunenge uchibata zvinhu zvakaoma (semuenzaniso mbabvu, magakanje) kana kuita mabasa anodzokororwa (semuenzaniso, kukanya mukanyiwa, kucheka), sarudza magirovhosi ane nitrile ane ukobvu huri pakati nepakati (kazhinji 0.08-0.12mm) uye anodzivirira kuboorwa kudzivirira kubvaruka kunogona kukonzera kusangana kwemaoko nechikafu.

• Kusapisa: Paunenge uchibata zvinhu zviri mufiriji (semuenzaniso, nyama dzakaomeswa nechando) kana kugara kwenguva pfupi pakupisa kwakanyanya (semuenzaniso, pedyo neovheni), tarisa kuti girovhosi haipindi kupisa kana kutonhora (nitrile inodarika PE nelatex). Izvi zvinodzivirira kuomarara, kutsemuka, kana kunyunguduka kwezvinhu.

• Kusapinda mvura: Pakubata zvinwiwa (semuenzaniso, masosi, mafuta, majusi), sarudza magirovhosi asina hupfu ane hunhu hwepamusoro hwekuvharira (nitrile > latex > PE) kudzivirira kupinda kwemvura kunogona kusvibisa maoko kana kukonzera kubuda kwegirovhosi yemukati kuti isvibise chikafu.

Pfupiso

Indasitiri yezvekudya inonyanya kukoshesa magirovhosi enitrile asina upfu akasimbiswa neFDA/EU 10/2011, akakodzera kugadziriswa uye kuchenesa. Magirovhosi ePE emhando yepamusoro anogona kushandiswa kwenguva pfupi kana akasangana nechikafu chakaoma. Nheyo huru: Iva nechokwadi chekutevedzera mitemo uku uchienzanisa dziviriro uye nyore kushanda kuti uderedze njodzi dzekurwara nezvirwere uye kusvibiswa.
