qhov tseem ceeb ntawm dej
Dej yog lub hauv paus ntawm lub neej. Dej tuaj yeem txhawb tib neeg cov metabolism, pab ua pa, thiab tswj lub cev kub. Kev haus dej tau dhau los ua kev ua neej nyob rau tib neeg. Nyob rau hauv xyoo tas los no, khob dej kuj tau hloov tshiab tas li, xws li Internet celebrity khob "Big Belly Cup" thiab tsis ntev los no nrov "Ton Ton Bucket". Lub "Big Belly Cup" yog nyiam los ntawm cov menyuam yaus thiab cov tub ntxhais hluas vim nws cov duab ntxim hlub, thaum qhov kev tsim kho tshiab ntawm "Ton-ton Bucket" yog tias lub raj mis tau cim nrog lub sijhawm thiab cov dej haus ntim ntsuas kom nco ntsoov cov neeg haus dej hauv. sij hawm. Raws li cov khoom siv dej haus tseem ceeb, koj yuav tsum xaiv li cas thaum yuav nws?
Cov ntaub ntawv tseem ceeb ntawm cov khoom noj khoom haus qib khob dej
Thaum muas lub khob dej, qhov tseem ceeb tshaj plaws yog saib nws cov khoom, uas cuam tshuam txog kev nyab xeeb ntawm tag nrho lub khob dej. Muaj plaub yam tseem ceeb ntawm cov khoom siv yas hauv khw: PC (polycarbonate), PP (polypropylene), tritan (Tritan Copolyester copolyester), thiab PPSU (polyphenylsulfone).
1. Cov khoom siv PC
PC nws tus kheej tsis muaj tshuaj lom, tab sis cov khoom siv PC (polycarbonate) tsis tiv taus qhov kub thiab txias. Yog tias nws yog cua sov los yog muab tso rau hauv qhov chaw acidic lossis alkaline, nws yuav yooj yim tso cov tshuaj lom bisphenol A. Qee qhov kev tshawb fawb qhia tau tias bisphenol A tuaj yeem ua rau muaj kab mob endocrine. Mob qog noj ntshav, rog rog tshwm sim los ntawm cov kab mob metabolic, puberty ntxov ntxov hauv cov menyuam yaus, thiab lwm yam tuaj yeem cuam tshuam nrog bisphenol A. Ntau lub tebchaws, xws li Canada, tau txwv tsis pub ntxiv bisphenol A hauv cov ntim khoom noj thaum ntxov. Tuam Tshoj tseem txwv tsis pub ntshuam thiab muag ntawm PC menyuam lub raj mis xyoo 2011.
Ntau lub khob dej yas ntawm lub khw yog ua los ntawm PC. Yog tias koj xaiv lub khob dej hauv PC, thov yuav nws los ntawm cov channel tsis tu ncua los xyuas kom meej tias nws tau ua raws li cov cai. Yog tias koj muaj kev xaiv, kuv tus kheej tsis pom zoo yuav lub khob dej PC.
2. PP khoom
PP polypropylene yog tsis muaj xim, tsis muaj ntxhiab, tsis muaj tshuaj lom, translucent, tsis muaj bisphenol A, thiab yog flammable. Nws muaj qhov melting point ntawm 165 ° C thiab yuav soften ntawm ib ncig ntawm 155 ° C. Kev siv kub ntau yog -30 ~ 140 ° C. PP tableware khob kuj yog cov khoom siv yas nkaus xwb uas tuaj yeem siv rau microwave cua sov.
3. cov khoom siv tritan
Tritan kuj yog ib qho tshuaj polyester uas daws tau ntau yam tsis zoo ntawm cov yas, nrog rau cov tawv tawv, cuam tshuam lub zog, thiab hydrolytic stability. Nws yog tshuaj-resistant, pob tshab heev, thiab tsis muaj bisphenol A hauv PC. Tritan tau dhau FDA daim ntawv pov thawj (Food Contact Notification (FCN) No.729) ntawm US Food and Drug Administration thiab yog cov khoom tsim los rau cov khoom me nyuam mos hauv Tebchaws Europe thiab Tebchaws Meskas.
4.PPSU khoom
PPSU (polyphenylsulfone) cov khoom yog amorphous thermoplastic, nrog kub tsis kam ntawm 0 ℃ ~ 180 ℃, muaj peev xwm tuav dej kub, muaj permeability siab thiab siab hydrolysis stability, thiab yog ib tug me nyuam lub raj mis cov khoom uas muaj peev xwm tiv taus chav sterilization. Muaj cov tshuaj carcinogenic bisphenol A.
Rau kev nyab xeeb ntawm koj tus kheej thiab koj tsev neeg, thov yuav cov fwj dej los ntawm cov channel tsis tu ncua thiab ua tib zoo xyuas cov khoom muaj pes tsawg leeg thaum yuav khoom.
Khoom noj khoom haus qib yas dej khob txoj kev tshuaj xyuas cov khob dej xws li "Big Belly Cup" thiab "Ton-ton Bucket" yog txhua yam ua los ntawm cov yas. Feem ntau qhov tsis xws luag ntawm cov khoom yas yog raws li hauv qab no:
1. Lwm cov ntsiab lus (muaj cov impurities): muaj cov duab ntawm qhov taw tes, thiab nws txoj kab uas hla tshaj plaws yog nws qhov loj me thaum ntsuas.
2. Burrs: Linear bulges ntawm cov npoo los yog cov kab sib txuas ntawm cov khoom yas (feem ntau tshwm sim los ntawm cov pwm tsis zoo).
3. Nyiaj hlau: Cov roj tsim thaum lub sij hawm molding ua rau saum npoo ntawm cov yas tsis muaj xim (feem ntau yog dawb). Feem ntau ntawm cov roj no
Nws yog cov dej noo hauv cov resin. Qee cov resins yooj yim nqus dej noo, yog li txheej txheem ziab yuav tsum tau ntxiv ua ntej tsim khoom.
4. Npuas: Cov chaw sib cais hauv cov yas tsim puag ncig ntawm nws qhov chaw.
5. Deformation: Deformation ntawm cov khoom yas tshwm sim los ntawm qhov sib txawv ntawm kev ntxhov siab los yog kev ua kom txias tsis zoo thaum tsim khoom.
6. Ejection whitening: Lub whitening thiab deformation ntawm cov khoom tiav los ntawm raug ejection los ntawm pwm, feem ntau tshwm sim nyob rau lwm kawg ntawm lub ejection ntsis (niam pwm nto).
7. Cov khoom siv tsis txaus: Vim muaj kev puas tsuaj rau cov pwm lossis lwm yam laj thawj, cov khoom tiav tuaj yeem tsis txaus thiab tsis muaj cov khoom siv.
8. Kev luam ntawv tawg: cov pob dawb hauv cov ntawv luam tawm los ntawm impurities lossis lwm yam laj thawj thaum luam ntawv.
9. Kev luam ntawv ploj lawm: Yog tias cov ntawv luam tawm tsis muaj khawb lossis cov ces kaum, lossis yog tias cov ntawv luam ntawv tsis raug ntau dua 0.3 hli, nws tseem suav tias yog kev luam ntawv ploj lawm.
10. Xim txawv: yog hais txog cov xim ntawm qhov tseeb thiab cov qauv pom zoo lossis xim xim ntau tshaj qhov tau txais txiaj ntsig.
11. Tib xim taw tes: yog hais txog qhov chaw uas cov xim nyob ze ntawm cov xim ntawm ib feem; txwv tsis pub, nws yog qhov sib txawv xim.
12. Flow streaks: Cov ntws streaks ntawm kub-melt yas sab laug ntawm lub rooj vag vim molding.
13. Weld marks: Linear marks formed on the surface of a part because of the convergence of two or more molten plastic kwj.
14. Sib dhos qhov sib txawv: Ntxiv rau qhov sib txawv uas tau teev tseg hauv kev tsim, qhov sib txawv tshwm sim los ntawm kev sib dhos ntawm ob yam khoom.
15. Fine khawb: nto khawb los yog cov cim tsis muaj qhov tob (feem ntau tshwm sim los ntawm kev tuav haujlwm).
16. Cov khawb tawv tawv: Cov kab sib sib zog nqus khawb ntawm qhov chaw uas tshwm sim los ntawm cov khoom tawv lossis cov khoom ntse (feem ntau tshwm sim los ntawm kev ua haujlwm ntawm phau ntawv).
17. Dent thiab shrinkage: Muaj cov cim qhia ntawm cov dents ntawm qhov chaw ntawm qhov chaw los yog qhov loj me dua qhov tsim loj (feem ntau tshwm sim los ntawm cov pwm tsis zoo).
18. Kev sib cais xim: Hauv kev tsim cov yas, cov strips lossis cov cim xim tshwm nyob rau hauv qhov chaw ntws (feem ntau tshwm sim los ntawm kev sib ntxiv ntawm cov khoom siv rov ua dua tshiab).
19. Kev pom tsis pom: txhais tau hais tias qhov tsis xws luag nrog txoj kab uas hla tsawg dua 0.03mm yog qhov tsis pom, tshwj tsis yog rau thaj tsam LENS pob tshab (raws li qhov ntsuas qhov deb tau teev tseg rau txhua qhov khoom).
20. Pob: tshwm sim los ntawm cov khoom nto los yog ntug raug ntaus los ntawm ib qho khoom tawv.
