kufunika kwa madzi
Madzi ndiye gwero la moyo. Madzi amatha kulimbikitsa kagayidwe ka anthu, kuthandizira thukuta, komanso kuwongolera kutentha kwa thupi. Kumwa madzi kwasanduka chizolowezi chamoyo kwa anthu. M'zaka zaposachedwa, makapu amadzi akhala akupanganso zatsopano, monga chikho cha intaneti "Big Belly Cup" komanso "Ton Ton Bucket" yotchuka posachedwa. "Big Belly Cup" imayamikiridwa ndi ana ndi achinyamata chifukwa cha mawonekedwe ake okongola, pomwe luso la "Ton-ton Bucket" ndikuti botolo limakhala ndi nthawi komanso masikelo amadzi akumwa kuti akumbutse anthu kumwa madzi. nthawi. Monga chida chofunikira chamadzi akumwa, muyenera kusankha bwanji pogula?
Zida zazikulu za makapu amadzi amtundu wa chakudya
Pogula kapu yamadzi, chofunika kwambiri ndikuyang'ana zinthu zake, zomwe zimaphatikizapo chitetezo cha chikho chonse cha madzi. Pali mitundu inayi ikuluikulu ya zida zapulasitiki zomwe zimagwiritsidwa ntchito pamsika: PC (polycarbonate), PP (polypropylene), tritan (Tritan Copolyester copolyester), ndi PPSU (polyphenylsulfone).
1. Zida za PC
PC palokha si poizoni, koma PC (polycarbonate) zinthu si kugonjetsedwa ndi kutentha kwambiri. Ngati itatenthedwa kapena kuikidwa pamalo a acidic kapena amchere, imatha kutulutsa mosavuta mankhwala oopsa a bisphenol A. Malipoti ena a kafukufuku amasonyeza kuti bisphenol A ingayambitse matenda a endocrine. Khansa, kunenepa kwambiri chifukwa cha matenda a kagayidwe kachakudya, kutha msinkhu msanga kwa ana, ndi zina zotero zingakhale zokhudzana ndi bisphenol A. Mayiko ambiri, monga Canada, aletsa kuwonjezera kwa bisphenol A muzosunga zakudya m'masiku oyambirira. China idaletsanso kulowetsa ndi kugulitsa mabotolo a ana a PC mu 2011.
Makapu ambiri amadzi apulasitiki pamsika amapangidwa ndi PC. Ngati mungasankhe kapu yamadzi ya PC, chonde iguleni kuchokera kumayendedwe okhazikika kuti muwonetsetse kuti imapangidwa motsatira malamulo. Ngati muli ndi chisankho, ine ndekha sindikulimbikitsani kugula kapu yamadzi ya PC.
2.PP zinthu
PP polypropylene ndi yopanda mtundu, yopanda fungo, yopanda poizoni, yowoneka bwino, ilibe bisphenol A, ndipo imatha kuyaka. Ili ndi malo osungunuka a 165 ° C ndipo idzafewetsa pafupifupi 155 ° C. Kugwiritsa ntchito kutentha ndi -30 ~ 140 ° C. Makapu a PP tableware ndiwonso zinthu zapulasitiki zokha zomwe zingagwiritsidwe ntchito potenthetsera ma microwave.
3.tritan zinthu
Tritan ndi polyester yamankhwala yomwe imathetsa zofooka zambiri zamapulasitiki, kuphatikiza kulimba, kulimba kwamphamvu, komanso kukhazikika kwa hydrolytic. Ndizosamva mankhwala, zimawonekera kwambiri, ndipo mulibe bisphenol A mu PC. Tritan yadutsa certification ya FDA (Food Contact Notification (FCN) No.729) ya US Food and Drug Administration ndipo ndizomwe zimagwiritsidwa ntchito popanga makanda ku Europe ndi United States.
4.PPSU zakuthupi
PPSU (polyphenylsulfone) zakuthupi ndi amorphous thermoplastic, ndi kutentha kukana kwa 0 ℃ ~ 180 ℃, akhoza kusunga madzi otentha, ali ndi permeability mkulu ndi mkulu hydrolysis bata, ndipo ndi ana botolo zakuthupi kuti kupirira nthunzi yotseketsa. Muli carcinogenic chemical bisphenol A.
Kuti mudziteteze nokha ndi banja lanu, chonde gulani mabotolo amadzi kuchokera kumayendedwe okhazikika ndikuwunika mosamala zomwe zidapangidwa pogula.
Njira yoyendera kapu yamadzi ya pulasitiki ya chakudya Makapu amadzi monga "Big Belly Cup" ndi "Ton-ton Bucket" onse amapangidwa ndi pulasitiki. Zowonongeka zodziwika bwino zamapulasitiki ndi izi:
1. Mfundo zosiyanasiyana (zokhala ndi zonyansa): zikhale ndi mawonekedwe a mfundo, ndipo kutalika kwake kwakukulu ndi kukula kwake pamene kuyeza.
2. Burrs: Ziphuphu zozungulira m'mphepete kapena mizere yolumikizana ya zigawo zapulasitiki (nthawi zambiri zimachitika chifukwa cha kusamaumbika bwino).
3. Waya wasiliva: Mpweya womwe umapangidwa powumba umapangitsa kuti mbali zapulasitiki zisinthe (nthawi zambiri zoyera). Yambiri mwa mipweya imeneyi
Ndi chinyezi mu utomoni. Ma resins ena amamwa mosavuta chinyezi, motero njira yowumitsa iyenera kuwonjezeredwa musanapange.
4. Miyendo: Malo akutali mkati mwa pulasitiki amapanga zozungulira zozungulira pamwamba pake.
5. Kusintha: Kusintha kwa zigawo za pulasitiki zomwe zimayambitsidwa ndi kusiyana kwapakati pa nkhawa kapena kuzizira kosauka panthawi yopanga.
6. Ejection whitening: Kuyera ndi kusinthika kwa chinthu chomalizidwa chifukwa chotulutsidwa mu nkhungu, nthawi zambiri kumachitika kumapeto kwina kwa ejection bit (mayi nkhungu pamwamba).
7. Kuperewera kwa zinthu: Chifukwa cha kuwonongeka kwa nkhungu kapena zifukwa zina, chotsirizidwacho chikhoza kukhala chosasunthika komanso chopanda zinthu.
8. Kusindikiza kosweka: Mawanga oyera m'mafonti osindikizidwa chifukwa cha zonyansa kapena zifukwa zina panthawi yosindikiza.
9. Kusowa kusindikiza: Ngati zosindikizidwa zikusowa zokanda kapena ngodya, kapena ngati chilema chosindikizira cha font chili chachikulu kuposa 0.3mm, chimaonedwanso kukhala chosowa chosindikiza.
10. Kusiyana kwamitundu: kumatanthauza mtundu wa gawo lenileni ndi mtundu wovomerezeka wamtundu kapena nambala yamtundu wopitilira mtengo wovomerezeka.
11. Malo amtundu wofanana: amatanthauza malo omwe mtunduwo uli pafupi ndi mtundu wa gawolo; apo ayi, ndi mfundo yamitundu yosiyana.
12. Mizere yoyenda: Mizere yoyenda ya pulasitiki yosungunuka yotentha imasiyidwa pachipata chifukwa cha kuumba.
13. Zizindikiro zowotcherera: Zilemba za mzere zomwe zimapangika pamwamba pa gawo chifukwa cha kulumikizana kwa mitsinje ya pulasitiki yosungunuka iwiri kapena kupitilira apo.
14. Kusiyana kwa Msonkhano: Kuwonjezera pa kusiyana komwe kumatchulidwa mu mapangidwe, kusiyana komwe kumachitika chifukwa cha kusonkhana kwa zigawo ziwiri.
15. Zing'onozing'ono zabwino: zokopa pamwamba kapena zizindikiro zopanda kuya (nthawi zambiri zimachitika chifukwa cha ntchito yamanja).
16. Zing'onoting'ono zolimba: Zing'onoting'ono zakuya pamwamba pazigawo zomwe zimayambitsidwa ndi zinthu zolimba kapena zinthu zakuthwa (nthawi zambiri zimachitika chifukwa cha ntchito zamanja).
17. Dent ndi shrinkage: Pali zizindikiro zowonongeka pamwamba pa gawolo kapena kukula kwake kuli kochepa kusiyana ndi kukula kwa mapangidwe (nthawi zambiri amayamba chifukwa cha kuumba kosauka).
18. Kulekanitsa mitundu: Popanga pulasitiki, mikwingwirima kapena madontho a madontho amtundu amawonekera m'malo oyenda (nthawi zambiri amayamba chifukwa chowonjezera zinthu zobwezerezedwanso).
19. Zosaoneka: zikutanthauza kuti zolakwika zomwe zili ndi m'mimba mwake zosakwana 0.03mm siziwoneka, kupatulapo LENS yowonekera (malinga ndi mtunda wodziwikiratu womwe umatchulidwa pagawo lililonse).
20. Bampu: chifukwa cha chinthu pamwamba kapena m'mphepete mwa chinthu cholimba.
