Qhov Tseem Ceeb rau Cov Ntaub Kho Mob Uas Ruaj Khov
Kev Cuam Tshuam Ib puag ncig ntawm Cov Ntaub Kho Mob Ib Txwm Muaj
Kuv feem ntau xav txog cov nqi zais ntawm cov ntaub kho mob ib txwm muaj. Cov txheej txheem tsim cov ntaub no feem ntau muaj cov tshuaj lom neeg hnyav. Cov tshuaj no ua rau muaj kev pheej hmoo loj rau ib puag ncig thiab kev noj qab haus huv. Piv txwv li, kuv pom tias qee cov tshuaj siv rau hauv kev zas xim thiab kev ua tiav tuaj yeem muaj cov teeb meem loj heev.
| Tshuaj lom neeg/Cov khoom lag luam | Qhov Tshwm Sim Ib Puag Ncig/Kev Noj Qab Haus Huv |
|---|---|
| Cov tshuaj aniline derivatives (aromatic amines) | Ua rau mob qog noj ntshav, tso tawm ntau hauv cov dej khib nyiab, cuam tshuam rau cov protein nqa oxygen (hemoglobin), ua rau methemoglobinemia (cyanosis, hypoxia), nephrotoxicity, hepatotoxicity, mob qog noj ntshav hauv lub zais zis, mob ntshav, ua haujlwm tsis zoo hauv lub siab thiab lub raum, muaj kev pheej hmoo siab rau ecological (av, dej, huab cua), lom rau cov tsiaj hauv dej hiav txwv, sib sau ua ke hauv cov tsiaj muaj sia, nkag mus rau hauv cov saw hlau zaub mov, tsim cov nitrosamine derivatives (carcinogenic) thaum photodegradation. |
| Cov xim azo (cov khoom ua ntej: acetanilide, phenylenediamines, alkyl-substituted anilines) | Kev txo qis hydrolysis tsim cov aromatic amines (aniline derivatives) uas muaj kev cuam tshuam loj heev rau ib puag ncig thiab kev noj qab haus huv. |
| Cov kua qaub, cov alkali, cov ntsev | Kev ua qias tuaj ntawm dej. |
Cov tshuaj lom neeg no ua rau peb cov dej tsis huv thiab ua rau cov tsiaj txhu hauv dej puas tsuaj. Lawv kuj tuaj yeem sib sau ua ke hauv cov tsiaj txhu uas muaj sia nyob, nkag mus rau hauv peb cov saw hlau zaub mov. Lub voj voog no tsim kev pheej hmoo siab rau ecological. Kuv ntseeg tias peb yuav tsum daws cov teeb meem no kom tiv thaiv peb lub ntiaj teb thiab peb txoj kev noj qab haus huv.
Kev Kho Mob Cov Pa roj carbon Footprint thiab Kev Tsim Khoom Siv Textile
Kuv paub tias kev kho mob cuam tshuam rau ib puag ncig tsis yog tsuas yog ua rau muaj kuab paug xwb. Cov pa roj carbon dioxide hauv kev lag luam tseem ceeb heev. Kev tsim cov ntaub ua rau muaj qhov teeb meem no. Cov txheej txheem siv zog ntau yog ib txwm muaj hauv kev tsim khoom. Cov txheej txheem no tso cov pa roj av rau hauv huab cua. Kev thauj cov khoom siv raw thiab cov khoom tiav lawm kuj ua rau muaj pa phem ntxiv. Kuv pom tias muaj kev xav tau kev hloov pauv. Kev txais yuav cov ntaub hnav kho mob uas ruaj khov tuaj yeem txo qhov kev nyuaj siab no. Nws pab peb txav mus rau lub cev kho mob ntsuab dua. Kuv xav tias muaj kev cog lus ruaj khov los nrhiav cov kev daws teeb meem zoo dua rau peb lub neej yav tom ntej.
Txhais thiab Tsim Kho Tshiab Cov Ntaub Hnav Kho Mob Uas Ruaj Khov
Cov Yam Ntxwv Tseem Ceeb ntawm Cov Ntaub Uas Ruaj Khov
Kuv ntseeg tias kev nkag siab txog cov yam ntxwv tseem ceeb ntawm cov ntaub uas ruaj khov yog qhov tseem ceeb. Cov yam ntxwv no mus dhau qhov tsuas yog "ntsuab." Lawv suav nrog kev siv cov ntaub ntawv kom zoo. Kuv nrhiav cov ntaub ntawv uas txo peb qhov kev cuam tshuam rau ib puag ncig. Piv txwv li, kuv xav txog cov ntaub ua los ntawm cov ntaub ntawv zoo rau ib puag ncig xws li paj rwb organic lossis polyester rov ua dua tshiab. Cov kev xaiv no txo cov pa roj carbon ntau heev.
Kev ruaj khov thiab lub neej ntev kuj tseem ceeb heev. Cov ntaub zoo thiab siv tau ntev txo cov khib nyiab. Lawv txuag cov peev txheej vim lawv tsis tas yuav hloov pauv ntau zaus. Kuv kuj tseem ceeb rau kev tsim khoom ncaj ncees. Qhov no txhais tau tias kev tsim khoom tshwm sim hauv qab kev ua haujlwm ncaj ncees. Nws ua kom cov neeg ua haujlwm noj qab haus huv zoo. Kev siv dej tsawg dua yog lwm qhov tseem ceeb. Cov txheej txheem zas xim tshiab thiab kev tsim khoom tuaj yeem txo qis kev siv dej. Cov ntaub uas muaj cov khoom tua kab mob kuj pab tau. Lawv txo qhov xav tau ntxuav ntau zaus, txuag dej thiab zog.
Kuv kuj xav txog cov tswv yim tsim uas tsom mus rau kev ncig. Qhov no suav nrog kev xaiv cov ntaub uas muaj cov pa roj carbon tsawg dua. Kuv nrhiav cov qauv tsim uas tso cai rau kev rhuav tshem. Qhov no ua rau cov kauj ruam tsim khoom tsawg dua, kev siv hluav taws xob, thiab kev tsim dej. Kev tsim cov khoom siv kuj tseem ceeb heev. Kuv xav txog kev siv cov khoom siv ntuj tsim thiab cov khoom siv mono-materials. Cov khoom kuj yuav tsum ntxuav tau, ntxuav tau, thiab siv tau dua. Lawv lub peev xwm rau kev siv dua thiab rov ua dua tshiab yog qhov tseem ceeb. Qhov tseem ceeb tshaj plaws, kuv xyuas kom meej tias kev nyab xeeb ntawm tus neeg mob tseem ceeb heev. Cov kev daws teeb meem yuav tsum muab qhov tseem ceeb rau qhov no thaum txo cov kev cuam tshuam rau ib puag ncig.
Cov Ntawv Pov Thawj thiab Cov Qauv rau Cov Ntaub Kho Mob Uas Ruaj Khov
Kuv paub txog qhov tseem ceeb ntawm cov ntawv pov thawj thiab cov qauv hauv daim teb no. Lawv muab ib lub moj khaum meej rau qhov ua rau cov ntaub hnav kho mob ruaj khov tiag tiag. Cov qauv no pab kuv txheeb xyuas cov lus thov los ntawm cov chaw tsim khoom. Lawv ua kom cov khoom ua tau raws li cov qauv ib puag ncig thiab kev sib raug zoo. Piv txwv li, cov ntawv pov thawj zoo li GOTS (Global Organic Textile Standard) ua kom cov khoom organic txij li kev sau cov khoom siv raw mus txog kev tsim khoom ib puag ncig thiab kev sib raug zoo. Oeko-Tex Standard 100 ua pov thawj tias cov ntaub tsis muaj cov tshuaj lom. Bluesign system ua kom cov txheej txheem tsim khoom ruaj khov. Kuv vam khom cov qauv no los coj kuv cov kev xaiv. Lawv pab kuv txheeb xyuas cov ntaub uas sib haum nrog peb lub hom phiaj kev ruaj khov. Cov ntawv pov thawj no tsim kev ntseeg siab thiab kev pom tseeb hauv cov khoom xa tuaj.
Cov Khoom Siv Kho Mob Uas Muaj Kev Ruaj Ntseg Zoo Tshaj Plaws
Kuv zoo siab heev rau cov kev tsim kho tshiab hauv cov ntaub siv kho mob uas ruaj khov. Cov ntaub tshiab no muaj cov txiaj ntsig zoo dua li cov kev xaiv ib txwm muaj. Kuv pom kev tsim cov ntaub ntawv biodegradable rau kev hnav qhov txhab. Cov no txhawb kev kho mob thaum txo cov khib nyiab. Cov ntaub ntawv biocompatible kuj tseem tsim cov scaffolds raws li ntaub. Cov no yog rau kev siv cov ntaub so ntswg. Lawv pab txhawb kev loj hlob thiab kho cov ntaub so ntswg rau cov mob xws li kub hnyiab thiab mob qog.
Kuv kuj pom kev siv ntawmpaj rwb organicCov neeg ua liaj ua teb cog qoob loo tsis siv cov tshuaj tua kab lossis cov chiv ua los ntawm cov khoom siv. Qhov no ua rau nws yog ib qho kev xaiv zoo rau ib puag ncig. Cov polyester rov ua dua tshiab yog lwm yam khoom siv zoo. Cov chaw tsim khoom tsim nws los ntawm cov fwj yas rov ua dua tshiab. Qhov no pab txhawb kev txo cov khib nyiab thiab kev txuag cov peev txheej. Xyoob yog ib qho khoom siv uas loj hlob sai, rov ua dua tshiab. Nws yog cov tshuaj tua kab mob ntuj thiab lwj tau. Kuv pom nws cov khoom zoo tagnrho rau kev siv kho mob. Kelp Clothing, piv txwv li, tau tsim ib kab ntawm cov khaub ncaws txhuam kom ruaj khov. Nws muaj cov seaweed ua cov khoom siv tseem ceeb. Qhov no sawv cev rau kev siv cov khoom siv ntuj tsim hauv cov khaub ncaws kho mob.
Cov ntaub zoo heev no muaj kev ua tau zoo heev. Lawv muab kev lim dej zoo heev thiab permeability. Ntau yam yog pob tshab. Lawv kuj siv tau dua tom qab ntxuav lossis tua kab mob. Lawv feem ntau muaj cov khoom tiv thaiv kab mob thiab tiv thaiv kab mob. Cov txheej txheem ua ntsuab kuj tseem tab tom tshwm sim. Plasma technology tsim cov ntaub ua haujlwm nrog cov teebmeem tshwj xeeb ntawm qhov chaw. Piv txwv li, cov ntaub tuaj yeem hydrophilic ntawm ib sab thiab hydrophobic ntawm qhov tod tes. Supercritical carbon dioxide extraction tsim cov ntaub ntawv porous. Cov no tau txhim kho cov yam ntxwv kev thauj mus los. Lawv tsim nyog rau ultrafiltration substrates. Cov ntaub ntawv ntuj xws li paj rwb kuj tseem tab tom tsim. Lawv dhau los ua cov ntaub ua haujlwm siab. Lawv muab cov txiaj ntsig ib puag ncig xws li biodegradability. Lawv sib tw nrog cov khoom siv hluavtaws hauv cov ntawv thov xws li cov ntaub so ntswg thiab cov ntaub so ntswg sab saum toj.
Dr. Acevedo hais tias cov ntaub kho mob niaj hnub yuav tsum ua ntau dua li tsuas yog npog cov qhov txhab lossis muab kev txhawb nqa. Kuv pom zoo. Lawv yuav tsum tswj cov dej noo, tswj qhov kub, thiab pab kho kom rov zoo. Lawv yuav tsum ua qhov no yam tsis muaj cov tshuaj lom neeg lossis kev cuam tshuam rau ib puag ncig. Huffman sau tseg tias cov ntaub siab heev tuaj yeem tswj cov ntxhiab tsw, tawm tsam hluav taws xob, tiv thaiv cov plaub tsiaj, thiab tiv taus kev hnav ntxiv. Lawv tseem nyob ruaj khov thoob plaws lawv lub neej. Kuv pom cov kev tsim kho tshiab no ua cov kauj ruam tseem ceeb rau pem hauv ntej.
Cov txiaj ntsig thiab kev siv cov ntaub hnav khaub ncaws kho mob uas ruaj khov
Kev Xis Nyob thiab Kev Ruaj Kho Mob Zoo Dua Nrog Cov Ntaub Siv Kho Mob Uas Ruaj Khov
