(1) zais qhov phom sij ntawm cov khoom ntim
Tam sim no, muaj ntau lub thawv ntim khoom noj thiab cov khoom ntim tau tso cai hauv kuv lub tebchaws, thiab cov khoom siv sib txawv tuaj yeem ua rau muaj kev nyab xeeb sib txawv. Yas yog ib qho ntawm cov khoom ntim khoom siv dav siv ntau tshaj plaws. Nws cov teeb meem feem ntau yog los ntawm cov tshuaj lom monomers thiab pyrolysates nyob hauv cov khoom. Cov khoom siv ntawv kuj yog cov khoom ntim khoom noj ib txwm muaj. Cov khoom siv raw siv hauv kev tsim cov ntawv ntim zaub mov yuav tsis huv, thiab tej zaum yuav muaj teeb meem ua paug xws li cov hlau hnyav, cov tshuaj tua kab, thiab txawm tias siv cov ntawv pov tseg ua cov khoom siv raw, ua rau cov tshuaj lom neeg thiab cov pa phem microbial. Cov khoom siv roj hmab feem ntau siv hauv cov khoom ntim khoom noj tuaj yeem muaj kev phom sij los ntawm cov roj hmab hluavtaws monomers lossis kev pabcuam ua haujlwm. Tsis tas li ntawd, cov tshuaj lom hlau ions tuaj yeem ua los ntawm cov khoom ntim hlau, silicon dioxide tuaj yeem yaj los ntawm cov ntaub ntawv iav, thiab cov hlau oxides kuj tuaj yeem yaj los ntawm ceramic glazes.
(2) Tsis raug cai ntxiv ntawm ntau yam kev pab cuam hauv kev tsim khoom
Kev tsim khoom tsis tu ncua ntawm cov khoom ntim lossis ntim khoom kuj yog ib qho laj thawj tseem ceeb rau kev nyab xeeb khoom noj. Tam sim no, cov tuam txhab khoom noj feem ntau tsis tso cai rau cov tuam txhab ntim khoom kos npe rau lawv cov khoom, uas ua rau cov neeg siv khoom tsis tuaj yeem txheeb xyuas" qhov chaw ntawm keeb kwm" ntawm lub ntim. Txij li cov neeg siv khoom tsis tuaj yeem saib xyuas, cov tuam txhab khoom noj feem ntau txiav txim siab yuav ntau yam kev pab cuam raws li seb tus nqi qis, uas ua rau muaj kev phom sij rau cov zaub mov zais. Piv txwv li, plastics yog high-molecular polymers, uas yog tsim los ntawm polymerization ntawm monomers thiab pib nyob rau hauv tsim nyog tej yam kev mob. Txhawm rau txhim kho kev ua haujlwm ntawm cov yas thiab kev siv cov khoom tiav, cov kev pab cuam xws li plasticizers, antistatic agents, smoothing agents, thiab heat stabilizers yuav tsum tau ntxiv rau hauv cov txheej txheem khoom tiav. Plastic monomers thiab kev pab ua haujlwm yog cov khoom sib xyaw uas tsis tshua muaj molecular. Nyob rau hauv qee qhov nruab nrab thiab qhov kub thiab txias, lawv yuav yaj los ntawm cov yas thiab hloov mus rau cov khoom noj, yog li ua rau cov zaub mov tsis zoo thiab ua rau muaj kev phom sij rau tib neeg kev noj qab haus huv.
(3) Ntim thiab luam ntawv muaj kuab paug
Ink yog ib qho khoom siv tseem ceeb rau kev ntim khoom thiab luam ntawv, thiab nws kuj yog ib qho tseem ceeb ntawm cov khoom noj paug. Muaj ob hom kev ntim cov ntawv luam tawm ib txwm muaj: resin-based thiab hnyav-raws li. Thaum luam ntawv nrog ob tus cwj mem no, qee yam khoom tsis zoo xws li cov hlau hnyav, cov organic volatiles thiab hnyav residues yuav raug tsim.
(4) Ntim cov qauv kuaj
Yog li ntawd, qhov zoo ntawm lub hnab ntim khoom noj hauv kev lag luam ntim khoom yooj yim, tshwj xeeb tshaj yog kev nyiam huv, yog ncaj qha ntsig txog kev nyab xeeb ntawm cov khoom ntim khoom. Yog li ntawd, nws yog ib qho tsim nyog los xyuas kom meej tias cov khoom siv raw thiab cov khoom siv ntxiv ua tau raws li qhov kev xav tau ntawm kev tswj hwm. Nws yog ib qho tsim nyog los txhim kho thiab nruj me ntsis ua raws li cov qauv kev lag luam ntim cov hnab ntim khoom lag luam thiab cov qauv hauv tebchaws, ntxiv dag zog rau kev tshuaj xyuas thiab saib xyuas cov ntim khoom noj, tiv thaiv kev ntim khoom tsis tsim nyog los ntawm kev nkag mus rau hauv kev ua lag luam, ntxiv dag zog rau kev tswj hwm, thiab xyuas kom muaj kev noj qab haus huv ntawm kev lag luam ntim khoom lag luam. Kev ntim khoom noj khoom haus ib lub hnab ntim tshuaj ntsuam xyuas yog muab faib ua pawg hauv qab no:
1. Cov tsos tsis muaj qhov tsis xws luag xws li npuas, perforations, kab dej, tawg, tsis zoo plasticization, thiab ntses-qhov muag blocks.
2. Lub cev thiab cov khoom siv kho tshuab suav nrog lub zog tensile thiab elongation ntawm kev tawg, uas cuam tshuam lub peev xwm tensile ntawm cov khoom thaum siv. Yog tias cov khoom no tsis tsim nyog, lub hnab ntim khoom noj yuav yooj yim tawg thiab puas thaum siv.
3. Tensile lub zog thiab elongation ntawm kev tawg, nws qhia txog lub peev xwm ntawm cov khoom kom tiv taus qhov nro thaum siv. Yog tias cov khoom no tsis tsim nyog, lub hnab ntim khoom noj tau yooj yim tawg thiab puas thaum siv.
4. Gas barrier zog xws li roj permeability (oxygen permeability, ya raws permeability, huab cua permeability).
5. Roj kuj Performance index, kub tsis kam, txias kuj, nruab nrab kuj; cov ntsuas no qhia txog kev ntseeg siab ntawm cov hnab ntim khoom noj los tiv thaiv lub ntim sab hauv.
