Ua ntej, cov ntaub ntawv yas nrog cov khoom siv zoo sib xws thiab tib txoj kev tsim khoom tuaj yeem faib cov pwm pwm. Txawm li cas los xij, cov no yog raws li ntau yam kev mob, xws li cov txheej txheem ntawm cov khoom, qhov nyuaj ntawm kev tsim khoom, cov yam ntxwv ntawm cov khoom nws tus kheej, thiab lwm yam. Yog tias cov xwm txheej saum toj no tau ntsib, piv txwv li, AS lub raj mis tshuab pwm thiab PC cov ntaub ntawv tuaj yeem sib koom ua ke pwm, thiab PC yas pwm tuaj yeem sib koom pwm tib yam nrog cov khoom siv Tritan, tab sis nws yuav tsum tsis yog vim AS tuaj yeem sib koom nrog PC, thiab PC tuaj yeem siv nrog Tritan sib koom txhais tau tias AS thiab Tritan cov ntaub ntawv tuaj yeem sib koom ua ke. teeb ntawm pwm. Cov txheej txheem ntau lawm ntawm AS thiab tritan yog qhov sib txawv, thiab cov khoom lag luam kuj txawv heev.
Qhov thib ob, muaj ntau qhov xwm txheej uas tib txheej pwm tsis tuaj yeem sib koom. Siv lub khob kas fes pov tseg yooj yim ua piv txwv. Lawv kuj yog cov pwm txhaj tshuaj, tab sis yog tias cov ntaub ntawv yog melamine thiab Tritan, lawv yuav tsum tsis txhob faib cov mols. , vim hais tias ob cov ntaub ntawv muaj qhov sib txawv kiag li rau cov txheej txheem ntau lawm, nrog rau qhov kub thiab txias, siab, lub sij hawm ntau lawm, thiab lwm yam uas yuav tsum tau rau ntau lawm. Txawm hais tias nws yog kev txhaj tshuaj pwm lossis lub raj mis tshuab pwm, tus editor nkag siab qhov kev xav ntawm cov phooj ywg yuav khoom zoo heev. Tom qab tag nrho, tus nqi ntawm cov pwm yas yog qhov siab, thiab kuv vam tias lawv tuaj yeem siv tau ntau li ntau tau, yog li cov phooj ywg yuav tsum xav txog ua ntej cov khoom siv twg los txiav txim siab txog cov khoom yas. , ntawm chav kawm, qhov chaw tsim nyog yog tsim nyog ua ntej yuav khoom thiab kev nqis peev hauv cov nqi-zoo.
Ib yam li ntawd, cov khoom siv yas PP yog mos thiab tej zaum yuav raug shrinkage thiab lwm yam khoom hloov thaum lub sij hawm tsim khoom, yog li nws tsis tuaj yeem sib koom pwm nrog lwm cov ntaub ntawv yas.
Thiab los teb ib tug phooj ywg cov lus nug, nws puas txhais tau hais tias tus nqi ntawm cov ntaub ntawv yas ntau dua, cov txheej txheem kev siv tshuab ntau dua, thiab tib lub sijhawm, cov nqi tsim khoom yuav zoo dua? Cia kuv tham luv luv txog qhov no, vim hais tias yog tias qhov teeb meem no tau tham los ntawm kev xav txog kev tshaj lij, ib phau ntawv tuaj yeem luam tawm, tab sis tib lub sijhawm, nws muaj tseeb tias peb tsis muaj peev xwm no.
Cov kev xav tau ntawm cov txheej txheem tsim khoom tsis yog nyob ntawm cov ntaub ntawv, tab sis kuj nyob ntawm cov qauv khoom thiab cov khoom tiav cov khoom zoo. Tus nqi tsim khoom sib txheeb ntawm cov khoom siv siab yuav tsum siab, tab sis nws tsis tau txhais hais tias ntau lawm yuav siv sij hawm ntev dua los yog cov nqi zog ntau lawm, tab sis cov khoom siv nqi siab.
