Cov khob yas xa mus rau cov thawv pov tseg uas siv los tuav cov dej qab zib thiab tshuaj yej. Cov khoom tsis yog degradable yog lub ntsiab lus ntawm "dawb paug". Kev siv cov phom kub ntau tshaj plaws yog cov khw muag khoom noj haus, dej kub thiab txias haus, cov khw muag tshuaj, cov khw muag khoom, cov khw noj mov thiab cov khws kas fes, uas muaj ntau lub khob thiab haus dej haus thiab siv nyob rau hauv.
Lub khob yog ib yam khoom uas tsis yog biodegradable, thiab ntau tus neeg pov nws tam sim ntawd tom qab haus dej, ua cov yas yas uas yog siv "white pollution".
Hauv qab naj npawb qhia tias lub ntsiab lus
1 PET polyethylene terephthalate
Cov kaus poom dej ntxhua khaub ncaws ntau, cov dej haus cov dej haus thiab lwm yam. Tshav kub rau 70 ℃ yog yooj yim deformation, RongChu teeb meem tshuaj. Tom qab 10 lub hlis yas 1, tus kabmob carcinogen DEHP yuav raug tso tawm. Tsis mus hauv lub tsheb npav hauv lub hnub; Txhob ntim dej cawv, roj, thiab lwm yam
HDPE HDPE 2
Cov tshuaj dawb dawb lub raj mis, cov khoom siv tu khoom, cov khoom siv da dej. Tsis txhob siv nws ua dej khob, lossis muab lub thauv cia rau lwm yam khoom. Tu tsis huv, tsis txhob rov qab ua dua qub.
PVC PVC rau tsis muaj. 3
Hom dej nag, cov khoom siv hauv tsev, yas yeeb yaj duab, thawv yas, thiab lwm yam. Cuav zoo, qhov pheej yig, yog li nws yog ib qho siv. Tsuas yog 81 ℃ heat. Yooj yim los tsim cov khoom phem ntawm kev kub, tsis tshua siv nyob rau hauv cov zaub mov ntim. Tsis txhob yoojyim, tsis txhob rov qab ua dua. Tsis txhob yuav yog tias koj haus.
No.4 PE polyethylene
Cov yeeb yaj kiab pluaj, yas zaj duab xis thiab lwm yam. Thaum muaj kev kub ntxhov, cov khoom tsim teeb meem raug tsim tawm, thiab tshuaj lom yuav ua rau muaj kab mob xws li mob cancer mis thiab yug me nyuam yug los. Tsis txhob microwave lub hnab yas.
5 PP polypropylene
Cov kua mis ntau hom, kua mis nyeem qaub, kua txiv hmab txiv ntoo haus dej haus, lub qhov cub microwave. Raws li siab li 167 ℃, melting point yog tib lub thawv yas, muab tso rau hauv lub qhov cub microwave tau rov qab siv dua tom qab ua tib zoo ntxuav. Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias qee qhov microwave thawv yog ua los ntawm PP, tab sis lub hau ntawm lub thawv yog ua los ntawm PE 1, uas tsis tuaj yeem raug muab tso rau hauv lub qhov cub microwave vim PE tsis tuaj yeem ua siab kub.
6 PS polystyrene
Ib lub tais ntim cov thawv uas muaj cov thawv ntim thiab cov khoom noj ceev ceev. Tsis txhob muab tso rau hauv lub microwave kom tsis txhob tso chemicals uas kub heev. Thaum cov kua qaub (xws li txiv kab ntxwv kua txiv) thiab alkaline cov khoom muaj loaded, cov tshuaj carcinogenic tuaj yeem tsim tau. Tsis txhob ntim cov zaub mov kub hauv lub thawv ceev. Tsis txhob microwave ib lub tais ntawm instant noodles.
Lwm cov chav kawm ntawm PC 7
Dej ntau hom dej, chaw khob, lub fwj. Lub khw muag khoom feem ntau siv hom dej no los ua ib qho khoom plig. Nws yog ib qho yooj yim tso tawm lom bisphenol A, uas yog teeb meem rau tib neeg. Tsis txhob sov thaum siv. Tsis txhob coj nws mus rau hauv lub hnub.
muaj kev phom sij
Lub khob yas yog ib hom khoom uas siv ntau, tshwj xeeb tshaj yog ua kom lub raj mis, chaw khob thiab lwm yam. Lub xyoo dhau los, cov fwj cawv tau muaj teeb meem vim lawv muaj cov kab xuas paj hlwb A. Nyob hauv txoj kev xav, ntev li 100 feem pua ntawm kev hloov pauv mus rau hauv cov txheej txheem ua cov yas yas, cov kws txawj hais tias, cov khoom tsis muaj bisphenol A, tsawg dua tso tawm. Txawm li cas los xij, yog hais tias Ib tug me me ntawm bisphenol A tsis hloov mus rau hauv lub khob yas, nws yuav raug tso tawm mus rau hauv cov zaub mov los yog haus. Cov seem ntxiv bisphenol A nyob rau hauv lub khob yas, lub siab dua qhov kub, qhov ntau qhov kev tso tawm, ceev ceev. Yog li, tsis muaj dej kub yuav tsum tau muab rau hauv PC. Yog tias muaj qoob lossis tawg ntawm lub khob ntim, nws raug nquahu kom tsis txhob siv nws, raws li qhov khoom ntawm cov khoom yas yog qhov yooj yim zais yog tias muaj me me qhov tsua noob. Txhob siv cov khoom siv yas laus rov qab siv dua.
Ntxiv rau kev ua kom sov, yas khob tuaj yeem tso chemicals thiab kab mob. Txawm hais tias cov yas ntsa yuav zoo li zoo, muaj ntau ntau khoob thiab yooj yim kom raug kuab. Nyob rau hauv qhov chaw ua hauj lwm, lub khob yog feem ntau ntxuav nrog dej, lub khob yog tsis huv si thiab disinfected. Cov kws kho mob hais tias lub chaw ua haujlwm yuav tsum raug ntxuav nrog lub khob tsis muaj lub khob los sis iav txhua hnub, zoo li siv lub xab npum thiab muab yaug nrog dej kub.
Tsis tas li ntawd, lub khob raug cuam tshuam los ntawm hluav taws xob zoo li lub computer, lub thawv ntim tshuab, yuav nqus hmoov av, kab mob, kab mob, ntev yuav cuam tshuam kev noj qab haus huv. Rau qhov kawg, Suav hluav taws xob kev tshawb fawb tshawb fawb lub teb chaws kev saib xyuas thiab kev soj ntsuam chaw ntawm cov khoom siv hluav taws xob hauv tsev los ntawm jian-guo lu, tus thawj coj ntawm lub tuam txhab tshuaj ntsuam xyuas txhua tus, zoo dua muab lub khob nrog lub hau, thiab tsis tau ze rau cov khoom siv xws li tshuab computer, thaum lub sij hawm zoo tib yam yuav tsum muaj vaj tse nyob hauv tsev, qhib qhov rai cua, cia plua plav mus.
Iav yuav tsum yog thawj qhov kev xaiv. Tsis txhob xav hais tias lub khob yog dawb xwb, tab sis nyob rau hauv tag nrho cov khoom khob, lub khob yog qhov zoo tshaj plaws.
Cov iav nyob rau hauv txoj kev tua hluav taws uas tsis muaj cov organic tshuaj, thaum neeg siv ib khob dej los yog lwm cov dej haus, tsis tas yuav txhawj txog cov tshuaj ua dej haus tau hauv plab, thiab iav ntsa yog du, yooj yim los ntxuav, ntawm cov kab mob thiab cov av tsis yooj yim rau hauv iav, yog li cov neeg siv ib khob dej yog qhov zoo tshaj plaws thiab muaj kev nyab xeeb.
Tsis tas li ntawd, tus kws tshaj lij kuj tseem siv cov ntaub ntim kabmob, vim hais tias lub khob ntim tom qab kub kub ntawm qhov kub siab, tsis muaj hmoov txhuas thiab lwm yam tsim teeb meem, yuav siv tau yam xyuam xim.
Lub koob ntim muaj xim zoo nkauj txaus nyiam, tab sis qhov tseeb nkaum hauv lub xim nrig uas loj heev thaum teeb meem, tshwj xeeb tshaj yog cov phab ntsa pleev xim rau cov xim ci, siab thaum lub khob ntim rau hauv dej kub, kua qaub lossis alkaline haus, thiab cov yeeb nkab hnyav hlau xws li txhuas nyob hauv cov xim yog yooj yim yaj rau cov kua, cov neeg haus dej rau hauv cov kua tshuaj, yuav tsim teeb meem rau tib neeg lub cev. Thiab feem ntau ntxiv cov yas plasticizer, uas muaj qee cov tshuaj lom, cov khob dej kub lossis dej kub, tshuaj lom uas lom tau yooj yim rau hauv dej, thiab cov nplais loj hauv microscopic muaj ntau cov pore, uas hides av, tu tsis net yuav yooj yim rau cov kab mob yug menyuam. Yog li, cov kws qhia nco ntsoov, thaum xaiv cov khob yas, yuav tsum xaiv lub khob dej uas haum raws li lub teb chaws tus qauv tsim tau qib yas.
