Yuav ua li cas txhawm rau txhim kho qhov ua tau zoo ntawm cov kua nplaum ua kua nplaum ntawm cov kab xev uas tsis muaj seem

Rau cov kab xev uas siv PP thiab PET cov txheej txheem, "tsis muaj qhov seem" xav tau cov nplaum siab ntawm cov nplaum-ua rau siab. Txhawm rau kom ua tiav qhov ua tau zoo tshaj plaws, cov kab xev tuaj yeem txiav txim siab siv PP, PET zaj duab xis kho corona, thiab tom qab ntawd ua lub hauv paus ntawm corona hauv PP, Tus tsiaj zaj duab xis txheej txheej txheej, txhawm rau txhim kho cov nplaum ntawm lub siab rhiab nplaum rau PP, PE, Tsiaj thiab lwm yam txheej txheem.

Cov kab xev tsim tau ua los ntawm ntau yam substrates. Nyob ntawm tus yam ntxwv ntawm tus qauv, cov substrate tuaj yeem yog polypropylene (PP), polyethylene (PE), polyvinyl chloride (PVC), polyester (PET), lossis polyimide (PI) zaj duab xis. Qee lub hom phiaj tshwj xeeb daim kab xev, tseem yuav siv cov yeeb yaj kiab hlau, xws li tooj liab, txhuas thiab lwm yam raws li cov khoom siv hauv paus. Ntawm cov txheej txheem no, daim kab xev nplaum tau siv.

Muaj ntau hom kab xev, vim muaj lub luag haujlwm sib txawv, thiab nrog rau qhov xav tau tiag tiag, yog li muaj ntau lub hom phiaj sib txawv ntawm daim kab xev. Adhesion, txawm li cas los xij, tseem yog qhov tseem ceeb tshaj plaws rau cov kab xev no. Lwm cov yam ntxwv, xws li huab cua tsis kam, tsis muaj qhov seem thiab ruaj khov siab, xav tau rau lub hom phiaj sib txawv.

Tsis muaj cov kua nplaum seem hais txog thaum daim kab xev tau ntuag tawm, tsis yog tawm ntawm cov kua nplaum (tsis muaj kua nplaum), txhim kho kev ua kom huv, thiab ua tiav cov txiaj ntsig zoo nkauj. Tsis muaj cov kab xev nplaum tshwj xeeb suav nrog cov hauv qab no:

Tsis txhob lo lo nplaum PP daim kab xev: tsis muaj cov nplaum nplaum kab xev pob tshab yog feem ntau nrog PP raws li txheej txheej, feem ntau yog siv rau laser phototypesetter, cov khw loj, cov khw muag khoom noj thiab cov khw noj mov rau cov ntawv tshaj tawm sab hauv, tsis pub dhau 7 hnub ntawm daim ntawv tshaj tawm sab nraum zoov, vaj tsev nyob nruab nrab muab tshuaj txhuam rau ntawm iav, xws li kev tshaj tawm, thiab tsev neeg thiab tsev kawm qib pib hauv cov chaw xws li tshaj tawm cov duab, ntawv, thiab lwm yam;

Cov nplaum uas tsis yog cov khoom seem (Bucky daim kab xev): Cov kab xev tsis nplaum (Bucky daim kab xev) feem ntau yog siv rau kev nthuav tawm sab hauv tsev lossis tsev so cov ntaub pua plag, lossis kho ib ntus hauv tsev kho av puas, lo rwb thaiv tsev paj rwb ntawm lub raj xa dej, kho rooj zaum thiab lwm yam tom qab siv tshuaj ntxuav;

Tsis-residual pob tshab PET daim kab xev: Tsis-residual pob tshab PET daim kab xev yog ua los ntawm cov ntaub yas polyester uas muaj lub zog iav zoo li cov txheej txheem sib xyaw thiab ib sab txheej nrog tshwj xeeb thermosetting hluavtaws roj hmab siab-rhiab nplaum. Feem ntau muaj feem xyuam rau kev hloov pauv hloov pauv, cov xov hluav taws xob txuas hluav taws xob txuas hluav taws xob, lub zog hluav taws xob, cov cuab yeej hnyav, cov ntawv qhwv thiab xim raj tawg-pov thawj, kua siv lead ua ntshav plahaum ceev thiab tsau rwb thaiv tsev.

Rau cov kab xev uas siv PP thiab PET cov txheej txheem, "tsis muaj qhov seem" xav tau cov nplaum siab ntawm cov kua nplaum ua kom siab. Rau qhov ua kom zoo tshaj plaws, cov kab xev tuaj yeem txiav txim siab:

Kev kho mob Corona yog ua los ntawm PP thiab PET zaj duab xis siv rau daim kab xev nplaum.

Qhov tshwm sim ntawm kev kho mob corona lossis nplaim hluav taws yog tsim los ntawm txheej txheej ntawm cov tshuaj sib txuas nrog cov pab pawg oxide nyob rau saum npoo ntawm cov khoom, yog li txhim kho polarity thiab tshuaj reactivity ntawm cov nplaim. Kev kho kab mob Corona lossis nplaim taws feem ntau yog ua los ntawm tus neeg muag khoom ua yeeb yaj kiab, yog tias koj xav tau ua nws tus kheej, koj yuav tsum ua tib zoo saib xyuas lub zog thiab lub sijhawm ntawm corona. Yog tias tsis muaj corona txaus, yuav tsis muaj cov pab pawg sib txawv txaus; Kev tiv thaiv kab mob corona ntau dhau yuav ua rau cov khoom siv puas tsuaj, txo cov khoom siv lub zog, thiab yog li txo qhov ua tiav zaum kawg. Ib qho ntxiv, kev kho mob saum npoo av feem ntau yog lub sijhawm-nkag siab. Txawm hais tias qhov nro ntawm daim nyias nyias nce ntxiv tom qab kev kho mob, lub xeev no lub cev tsis ruaj khov. Tom qab ib ntus, cov roj molecules me me hauv cov khoom siv hauv lub cev, xws li cov tshuaj hnyav hnyav hnyav los yog cov yas, thiab cov tshuaj muaj roj nyob hauv cov huab cua, yuav txav mus rau saum npoo ntawm daim nyias nyias, yog li txo qhov nro saum npoo dua. Qhov tshwm sim no muaj nyob hauv txhua cov ntaub ntawv corona, thiab tshwj xeeb tshaj yog cov khoom siv nrog iav hloov pauv kub qis dua chav sov, xws li PP, PE, thiab lwm yam.

2. Raws li kev kho mob corona, txheej PP, BOPP, PE daim kab xev nplaum | | hauv qab txheej txheej tus neeg sawv cev adhesion tus neeg sawv cev, txhawm rau txhawm rau txhim kho cov khoom nplaum ntawm cov kua nplaum siab.

Cov neeg saib hauv qab txheej, xws li Tebchaws Asmeskas rau Tuam Tshoj tianjin tuam txhab ntawm PP, BOPP, PE daim kab xev nplaum | | hauv qab txheej tus neeg sawv cev adhesion txhawb nqa kev ua haujlwm yog txhawm rau txhim kho cov nplaum ntawm cov nplaum thiab yas zaj duab xis. Ntxiv rau qhov tseem ceeb ntawm cov khoom siv nws tus kheej, txheej txheej txheej kuj tseem ua lub luag haujlwm tseem ceeb. Ua ntej tshaj plaws, los xyuas kom meej qee cov yeeb yaj kiab tuab. Feem ntau cov tuab zaj duab xis, qhov ua tau zoo dua ntawm kev tso tawm kev ntxhov siab, tau kawg, tus nqi yuav siab dua, ntau dua qhov ziab/kho qhov mob. Ib qho ntxiv, cov txheej txheem kom qhuav yuav tsum ua raws li tus neeg xa khoom cov lus qhia, raws li kev lag luam tus kheej cov cuab yeej siv khoom thiab txiav txim siab. Hauv txoj ntsiab cai, cov txheej txheej hauv qab yuav tsum qhuav tag nrho, txwv tsis pub nws yuav cuam tshuam rau nws txoj haujlwm. Cov yeeb yaj kiab sib txawv yuav muaj qhov txwv sib txawv ntawm qhov kub kom qhuav. Qhov kub tsis kam ntawm PET zaj duab xis siab dua li PP. Qhov kub kom qhuav kuj tseem tuaj yeem nce ntxiv kom txhim kho kev ua haujlwm tau zoo. Hauv txheej txheem kho cov txheej txheem txheej txheem, cov peev txheej kev pabcuam ntawm tus neeg xa khoom yog qhov tseem ceeb heev, thiab nws yuav tsum muaj peev xwm pab tus neeg siv los kho cov txheej txheem txheej txheem kom zoo tshaj plaws.
