Puas yog txhaj tshuaj molding tshuaj lom?

Lub toxicity ntawm txhaj tshuaj molded cov khoom yog ib tug complex teeb meem uas nyob ntawm ntau yam, nrog rau cov khoom xaiv, txheej txheem tswj, thiab kev siv ib puag ncig. Txawm hais tias muaj qee qhov kev pheej hmoo, los ntawm kev xaiv cov tuam txhab uas ntseeg siab, ua raws li cov lus qhia, thiab tshuaj xyuas cov khoom tsis tu ncua, kev pheej hmoo ntawm kev noj qab haus huv tuaj yeem txo. Tsis tas li ntawd, kev tswj hwm nruj thiab kev ntsuas kev nyab xeeb kuj tseem pab kom muaj kev nyab xeeb ntawm cov khoom txhaj tshuaj molded. Cov neeg siv khoom thiab cov chaw tsim khoom yuav tsum koom tes ua ke thiab ua haujlwm ua ke kom ntseeg tau tias qhov zoo thiab kev nyab xeeb ntawm cov khoom txhaj tshuaj molded.
1: Lub hauv paus ntsiab lus ntawm kev txhaj tshuaj molding txheej txheem
Ua ntej delving rau hauv seb cov khoom txhaj tshuaj molded puas muaj tshuaj lom, cia peb nkag siab txog cov hauv paus ntsiab lus ntawm kev txhaj tshuaj molding txheej txheem. Kev txhaj tshuaj molding yog txheej txheem tsim khoom uas koom nrog kev txhaj tshuaj molten yas rau hauv pwm, tso cai rau nws kom txias thiab tawv kom tsim cov duab uas xav tau. Cov txheej txheem no suav nrog cov kauj ruam tseem ceeb hauv qab no:
Kev pub mis: Cov khoom siv yas yog ntxiv rau hauv silo ntawm lub tshuab txhaj tshuaj molding.
Cua sov: Cov khoom siv raw yog rhuab rau hauv lub tog raj kheej cua sov kom txog thaum melted tag.
Txhaj Tshuaj: Molten yas yog txhaj rau hauv pwm kom puv pwm kab noj hniav.
Txias: Cov yas hauv pwm txias thiab tawv kom tswj tau cov duab uas xav tau.
Pwm qhib: Cov khoom tiav raug tshem tawm ntawm pwm thiab raug rau kev ua haujlwm tom ntej thiab tshuaj xyuas.
Cov txheej txheem no yuav zoo li yooj yim, tab sis nws muaj ntau yam uas yuav cuam tshuam rau qhov zoo thiab kev nyab xeeb ntawm cov khoom kawg.
2: Muaj peev xwm toxicity
Tam sim no cia peb saib yog vim li cas qee cov neeg txhawj xeeb txog kev nyab xeeb ntawm cov khoom txhaj tshuaj molded. Kev txhawj xeeb txog tej yam muaj kuab lom hauv kev txhaj tshuaj molded khoom feem ntau suav nrog cov hauv qab no:
Kev xaiv cov khoom siv yas: Cov khoom siv yas sib txawv muaj cov tshuaj sib txawv, thiab qee cov khoom yuav raug tso tawm raws li cov xwm txheej tshwj xeeb, ua rau muaj kev hem thawj rau tib neeg kev noj qab haus huv. Piv txwv li, qee cov yas yuav muaj cov yas yas, cov nplaim hluav taws, lossis lwm yam khoom siv ntxiv uas tuaj yeem nkag mus rau hauv qhov kawg txhaj tshuaj molded khoom.
Melting kub: Cov yas hauv lub tshuab txhaj tshuaj molding yog rhuab mus rau qhov kub siab heev, uas yuav ua rau qee cov yas tso tawm cov pa phem lossis cov tshuaj tsis haum cov organic (VOCs).
Insufficient solidification: Yog hais tias cov yas tsis txaus txias thiab hardened tom qab txhaj tshuaj, nws yuav ua rau muaj cov residual tshuaj lom nyob rau hauv cov khoom.
Kev ua haujlwm thib ob: Qee qhov kev txhaj tshuaj molded cov khoom yuav tsum tau ua cov kauj ruam ntxiv, xws li luam ntawv, txheej, lossis kev sib txuas, uas yuav qhia txog cov tshuaj lom.
Kev siv ib puag ncig: Cov khoom txhaj tshuaj molded thaum kawg yuav siv rau ntau qhov chaw, uas tuaj yeem ua rau tso cov khoom tsis zoo los ntawm cov yas, tshwj xeeb tshaj yog nyob rau hauv qhov kub thiab txias.
3: Kev tswj hwm thiab kev nyab xeeb
Txhawm rau kom muaj kev nyab xeeb ntawm kev txhaj tshuaj molded cov khoom, ntau lub teb chaws tau tsim cov qauv kev cai thiab kev ntsuas kev nyab xeeb. Cov qauv no feem ntau suav nrog kev xaiv cov ntaub ntawv yas, kev tswj cov txheej txheem, kuaj cov khoom, thiab kev sau ntawv. Cov hauv qab no yog qee qhov kev ntsuas kev tswj hwm:
Kev xaiv cov khoom siv: Thaum tsim cov khoom txhaj tshuaj molded, cov ntaub ntawv yas uas ua tau raws li cov qauv kev nyab xeeb thoob ntiaj teb feem ntau yog xaiv. Tshwj xeeb tshaj yog nyob rau hauv kev lag luam ntawm cov khoom ntim khoom noj thiab cov khoom siv kho mob, yuav muaj kev tswj xyuas nruj dua rau kev xaiv cov khoom siv.
Kev tswj cov txheej txheem: Cov chaw tsim khoom yuav tsum xyuas kom meej tias qhov ntsuas kub, siab, thiab lub sijhawm tsis ua haujlwm thaum lub sijhawm txhaj tshuaj molding yog nyob rau hauv qhov kev teev tseg los tiv thaiv kev tsim cov tshuaj phem.
Kev kuaj khoom: Cov khoom txhaj tshuaj molded feem ntau xav tau ntau yam kev ntsuam xyuas kom ntseeg tau tias lawv zoo thiab kev nyab xeeb. Cov kev ntsuam xyuas no yuav suav nrog kev tshuaj xyuas tshuaj, kev kuaj lub cev, thiab kuaj biocompatibility.
Kev txheeb xyuas thiab ntawv pov thawj: Qee lub tebchaws yuav tsum tau txhaj tshuaj molded cov khoom yuav tsum tau sau nrog cov ntaub ntawv tsim khoom, ua raws li cov qauv, thiab cov lus qhia kev nyab xeeb. Tsis tas li ntawd, qee cov khoom yuav xav tau cov ntawv pov thawj tshwj xeeb, xws li cov ntawv pov thawj zaub mov lossis ntawv pov thawj khoom siv kho mob.
4: Yuav ua li cas txo cov kev pheej hmoo
Txawm hais tias qee tus neeg yuav txhawj xeeb txog kev nyab xeeb ntawm kev txhaj tshuaj molded cov khoom, kev siv qee qhov kev ntsuas tuaj yeem pab txo qis kev pheej hmoo:
Xaiv cov chaw tsim khoom muaj kev ntseeg siab: Yuav cov khoom lag luam los ntawm cov tuam txhab muaj kev ntseeg siab uas feem ntau ua raws li cov qauv kev cai thiab siv cov kev tswj kom zoo.
Ua raws li cov lus qhia rau kev siv: Txawm hais tias nws yog lub thawv ntim khoom noj lossis cov khoom ua si, nws yuav tsum ua raws li cov lus qhia ntawm cov khoom kom ntseeg tau tias cov khoom siv nyob rau hauv kev nyab xeeb.
Zam kom tsis txhob kub thiab av noo ib puag ncig: Qee cov ntaub ntawv yas yuav tso tawm ntau yam teeb meem nyob rau hauv qhov kub thiab txias ib puag ncig, yog li sim zam kom tsis txhob nthuav tawm cov khoom rau cov xwm txheej no ntau li ntau tau.
Kev tshuaj xyuas cov khoom tsis tu ncua: Tsis tu ncua tshuaj txhaj tshuaj molded khoom rau cov kab nrib pleb, deformations, los yog lwm yam txawv txav. Yog tias muaj teeb meem, tam sim ntawd tsis txhob siv lawv.
Kev xaiv cov khoom sib txawv: Thaum yuav cov thawv ntim khoom noj thiab lwm yam khoom uas tuaj yeem cuam tshuam nrog cov khoom noj, cov khoom sib txawv tuaj yeem txiav txim siab los txo cov kev pheej hmoo.
