Momwe Mungasankhire Kapu Yapulasitiki Yotayika?

Makapu apulasitiki otayika amagawidwa m'mitundu itatu ndi zida

1. PET chikho

PET, No. 1 pulasitiki, polyethylene terephthalate, yomwe imagwiritsidwa ntchito kwambiri m'mabotolo a madzi amchere, mabotolo osiyanasiyana a zakumwa ndi makapu akumwa ozizira. Ndiosavuta kupunduka pa 70 ℃, ndipo zinthu zovulaza thupi la munthu zimasungunuka. Musawotche padzuwa, ndipo musakhale ndi mowa, mafuta ndi zinthu zina.

2. PS chikho

3. PP chikho

PP, No. 5 pulasitiki, polypropylene. Poyerekeza ndi PET ndi PS, chikho cha PP ndiye chida chodziwika bwino cha pulasitiki, chomwe chimatha kupirira kutentha kwa 130 ° C ndipo ndicho chidebe chokhacho cha pulasitiki chomwe chitha kuyikidwa mu uvuni wa microwave.

Posankha makapu amadzi otayidwa apulasitiki, zindikirani chizindikiro chapansi. No. 5 PP chikho chingagwiritsidwe ntchito pa zakumwa zozizira ndi zotentha, ndipo No. 1 PET ndi No. 6 PS zingagwiritsidwe ntchito pa zakumwa zozizira, kumbukirani.

Kaya ndi kapu yapulasitiki yotayidwa kapena kapu yamapepala, ndibwino kuti musagwiritsenso ntchito. Zakumwa zoziziritsa kukhosi ndi zotentha ziyenera kulekanitsidwa. Mabizinesi ena osaloledwa amagwiritsira ntchito mapepala otayidwanso ndi mapulasitiki okonzedwanso kuti apindule nawo. Ndizovuta kuwerengera zonyansa zonse, komanso zimakhala ndi zitsulo zolemera zosiyanasiyana kapena zinthu zina zovulaza. Choncho, ndi bwino kusankha mankhwala kuchokera kwa opanga nthawi zonse. Zomwe ogula wamba samamvetsetsa ndikuti pakati pa makapu apulasitiki otayika ndi makapu amapepala, zida zapulasitiki ndizopambana pamapepala. Zitha kuganiziridwa kuchokera kuzinthu ziwiri: 1. Njira yopangira makapu apulasitiki otayika ndi ophweka, ndipo ukhondo ndi wosavuta kulamulira. Makapu a mapepala ndi ovuta, okhala ndi maulalo ambiri opanga, ndipo ukhondo ndizovuta kuwongolera. 2. Kapu yapulasitiki yotayirapo, yopanda poizoni komanso yopanda kuipitsa. Ngakhale makapu oyenerera amapepala ndi osavuta kulekanitsa nkhani zakunja. Kuonjezera apo, zipangizo zomwe zimagwiritsidwa ntchito pa makapu a mapepala zimachokera kumitengo, yomwe imawononga nkhalango mopambanitsa ndipo imakhudza kwambiri chilengedwe.
