Cov dej ntws ua ntej yuav tsum tau ua ntej luam ntawv thiab kev siv cov yas yas
Peb yog ib lub tuam txhab luam ntawv loj hauv Shenzhen Tuam Tshoj. Peb muaj cov phau ntawv luam tawm, phau ntawv xov xwm luam ntawv, phau ntawv luam ntawv, phau ntawv nyuaj, phau ntawv luam tawm, phau ntawv luam tawm, phau ntawv luam tawm, lub thawv ntim, daim qhia ntawv, txhua yam ntawm PVC, cov ntawv luam tawm, ntawv sau cia, hom tshwj xeeb ntawv xim luam tawm khoom, kev ua si cardand li ntawd.

1. Cov qauv tsis muaj zog ntawm cov qauv molecular: Ntawm lub ntsiab substrates ntawm cov yas ntim yas thawv thiab luam ntawv, PE yog ib qho uas tsis-polar polymer organic compound nrog lub me me tseem ceeb nro, muaj zog inertia thiab tsis affinity nrog tus number case.
Txhua pawg ntawm PP muaj ib pawg methyl, uas yog pawg neeg tsis muaj zog, uas yog ib lub rooj ploj tsis muaj roj polymer organic, tab sis nws qhov kev nyuab siab tseem ceeb heev dua PE, yog li ntawm cov ntawv luam ntawm PP Nws zoo dua PE.
2. Qhov hluav taws xob sab nraud yog tsawg. Yas films xws li PE, PP, tus tsom, thiab pvc muaj qhov tsis tshua muaj zog. Qhov txo lub zog ntawm lub polymer, qhov me me ntawm qhov nro, thiab tsawg dua nws yuav tsum tau infiltrated los ntawm cov kua. Polyolefin plastics muaj cov cuab yeej no. Yuav kom tag nrho cov infiltrate tus number case thiab cov substrate, qhov siab nro ntawm lub substrate yuav tsum sib npaug los yog ntau dua li qhov nro ntu ntawm tus number case. Cov tshuaj no yog ua kom cov yas polyolefin los txhim kho nws lub zog.
3, qhov tshwm sim ntawm cov additives: PE, PP thiab lwm cov resins hauv cov txheej txheem tsim, thiaj li ua rau zaj nkauj yooj yim qhib, anti-static, anti-aging, anti-ultraviolet hluav taws xob thiab lwm yam khoom, nws yog ib qho tsim nyog los ntxiv ib qee qhov nyiaj ntawm cov khoom siv, xws li cov neeg sawv cev qhib, cov neeg siv tshuaj tiv thaiv, cov tshuaj tiv thaiv, thiab lwm yam., cov khoom ntxiv rau hauv lub pob zeb, cov txheej txheem ntawm cov khoom kub, qhov chaw tsiv tsuj zuj zus tuaj, ua cov roj ntsha, ua raws li lwm cov tshuaj. Cov phenomenon no yog nruam, yog li tom qab cov nplaim yas thiab cov khoom yas yog pretreated, nws tau luam tawm tam sim ntawd, thiab ntev lub sij hawm teev, qhov zuj zus ntawm kev ceev nrooj.
4. Siv zog ruaj khov. PE thiab PP films tsis tsuas muaj cov dej saum npoo, tab sis kuj tiv taus feem ntau ntawm cov kua qaub thiab alkali corrosion, thiab cov insoluble nyob rau hauv lub cev kub, kom lub adhesion ntawm zaj duab xis nto rau inks, xim, thiab cov zoo li yog pluag.
Qhov teeb meem saum no qhia tias polyolefin yas luam ntawv luam tawm yuav tsum tau ntim tshuaj ua ntej ob txoj kev ua xws li tsevneeg, kev pleev xim, kev sib txuas, electroplating, thiab bronze. Muab cov yas ntsa polarity, txhim kho qhov mob deg thiab kev ua haujlwm, thiab ua kom muaj kev sib koom ua ke.
