Bi-kev taw qhia polypropylene (bopp) feem ntau yog ntau-extruded zaj duab xis, uas yog tsim los ntawm polypropyles granules uas yog ncu hauv ob qho lus qhia, ntev ntev thiab kab rov tav. Cov yeeb yaj kiab no muaj lub zog zoo, cua tshuab hluav taws xob, muaj zog tsis kam, thiab yog cov khoom siv ntim khoom ntau ntxiv, thiab yog cov yeeb yaj kiab rau hauv BOPP. Nws tseem dav siv nyob rau hauv lub hnab woven.

Ntawm lub hauv paus ntawm cov khoom muaj nqis ntawm cov yeeb yaj kiab uas twb muaj lawm thiab txhim kho cov yeeb yaj kiab tseem ceeb ntawm kev txhim kho cov yeeb yaj kiab hauv khw hauv khw.

Cov yeeb yaj kiab no muaj lub zog zoo, cua tshuab hluav taws xob, muaj zog tsis kam, thiab yog cov khoom siv ntim khoom ntau ntxiv, thiab yog cov yeeb yaj kiab rau hauv BOPP. Nws tseem dav siv nyob rau hauv lub hnab woven.

Ntawm lub hauv paus ntawm cov khoom muaj nqis ntawm cov yeeb yaj kiab uas twb muaj lawm thiab txhim kho cov yeeb yaj kiab tseem ceeb ntawm kev txhim kho cov yeeb yaj kiab hauv khw hauv khw.

01. Ntev-ntev kev ua yeeb yam
Nyob rau hauv cov txheej txheem bopp zaj duab xis ntim kev siv, yeeb yaj kiab zoo li qub hluav taws xob los ntawm kev sib sau ua ke thiab hauv cov txheej txheem ntim khoom vim kev sib txhuam thiab electrostatic ob ntu. Cov hluav taws xob zoo li cas yuav ua rau nws tsim cov khoom zoo li qub, uas muaj qhov tsis zoo ntawm kev txiav, kev ua yeeb yaj kiab, thiab yuav ua rau zaj duab xis ntawm lub tshuab khiav tsis ua haujlwm. Yog li ntawd, yog tias tsuas yog electrostatic tus nqi ntawm cov yeeb yaj kiab nws tus kheej yog tsis quav ntsej, zaj duab xis yuav tau txais kev kawm tau zoo tab sis tas li thaum khiav ntawm lub tshuab.
Antistatic thaj chaw yog ib qho ntawm cov kev cai kom du. Ntev ntev ntev lossis siv cov tshuaj tiv thaiv ib txwm siv, tab sis ntxiv rau kev sib txuas ntau yog muaj nuj nqis thiab muaj qhov cuam tshuam tsis zoo ntawm cov khoom siv kho tshiab. Ntawm lub hauv paus ntawm tam sim no thev naus laus zis, qhov zoo tshaj plaws, du cov tshuaj tua kabmob uas muaj me me ntawm cov neeg saib xyuas kev tshawb fawb me me yuav yog ib qho ntawm cov kev tshawb fawb tseem ceeb. Kev tshawb nrhiav hauv cov yeeb yaj kiab hauv cov yeeb yaj kiab ntev nrog cov tshuaj tua kabmob ntev tuaj yeem pom zoo los ntawm ob qho: ua ntej, polarization ntawm lub npoo ntawm cov yeeb yaj kiab bopp; Thib ob, kom tshem tau ntawm cov kev vam khom ntawm cov tshuaj tiv thaiv ntawm cov av noo thiab ntxiv cov tshuaj tiv thaiv ncaj qha rau txheej txheej saum npoo.

02. Sib txhuam sib txhuam
Nyob rau hauv Bopp zaj yeeb yaj kiab, muaj ntau yam uas cuam tshuam rau coefficient ntawm kev sib txhuam:

(1) hom toner. Silicone roj thiab kev lom zem ntaus toner muaj cov kev ua tau zoo thiab qis dua cov ntaub ntawv tsis muaj qhov kub thiab txias chav tsev muaj kev lom zem dua. Cov neeg sawv cev npleem tuaj yeem txo cov coefficient ntawm kev txhuam hniav, uas yog qhov tseem ceeb uas cuam tshuam rau kev sib txhuam ua haujlwm ntawm zaj duab xis.

(2) anti-adhesive tus neeg sawv cev. Anti-adhesive tus neeg sawv cev yog feem ntau cov particle loj ntawm cov duab zaj duab xis, yuav ua rau cov duab ua yeeb yaj kiab, nws yuav ua rau lub ntsej muag zoo nkauj, yuav ua rau lub ntsej muag ua si, yuav yooj yim dua, kom yooj yim rau kev sib txhuam.

(3) tus sawv cev antistatic. Feem ntau siv nyob rau hauv cov neeg sawv cev ntxiv yog surfactanic yog surfactants, tuaj yeem txo cov nrhav ntawm zaj duab xis, yog li txo cov coeffient ntawm kev sib txhuam.

03, tsis tshua muaj cua sov kev ua tau zoo
Cov kev ua si kub hnyiab tau kev ua yeeb yam ntawm BOP zaj yeeb yaj kiab yog qhia txog kev kub hnyiab thiab kub sib khi lub zog yuav tsum tau tswj hwm ntawm 85 ~ 110 ℃. Cov tshuab ntim ntim sib txawv ntim, cov cua sov sib txawv yog qhov sib txawv, thiab tib cov qauv ntawm cov khoom ua haujlwm hauv kev ua haujlwm sib txawv, qhov kub tau sib txawv. Yog li ntawd, cov ntau ntawm cov kub sib khi kub ua rau zaj duab xis muaj qhov kub ua kom muaj zog sib yoog

04. GLAL siab, Lauj Hav Zoov
Ntxiv rau kom ua kom muaj kev ua yeeb yaj kiab uas tau ntim rau ntawm lub tshuab kom zoo, cov haujlwm tseem ceeb tshaj plaws ntawm Bopp ntim khoom zaj duab xis yog lub ntim ntim ntim hluav taws xob ci. Los ntawm cov ntsiab cai ntawm cov ntsiab cai ntawm Optics, ob qhov tseem ceeb tseem ceeb ntawm lub zog kho qhov muag ntawm cov yeeb yaj kiab hauv cov yeeb yaj kiab hauv cov yeeb yaj kiab, namely gloss thiab kub kub.
Glossable yog siv los ntsuas qhov pom ntawm cov zaj duab xis. Lub teeb ntau dua yog ncaj qha los ntawm zaj duab xis saum npoo, qhov ntau dua yog qib gloss. Cov chaw pom pom zoo siab pom tias lub teeb ci siab thiab muaj kev cuam tshuam cov duab kom meej. Qhov saum npoo ntawm Bopp zaj yeeb yaj kiab yuav tsum yog li ntawd muaj qib siab ntawm cov tiaj tiaj tiaj. Nadyuam, connively hu ua transparency, yog kev ntsuas ntawm feem pua ​​ntawm kev sib kis lub teeb uas deviates los ntawm qhov xwm txheej teeb los ntawm ntau dua ib lub kaum kev ntawm lub teeb. Thaum tawg ntawm lub kaum sab xis me me, cov ntsiab lus ntawm lub ntim yog qhov tseeb xwb; Ib qho loj thiab tsis sib xws ua kom lub kaum sab xis yuav ua rau txo qis dua thiab muaj qhov qis dua thiab muaj kuab ntau dua thiab muaj kuab ntawm cov khoom sab nraud.

Nyob rau tam sim no, Bopp zaj duab xis yog xav daws cov teeb meem kev ua yeeb yam, tom qab muaj qee qhov teeb meem tau daws teeb meem, tab sis muaj qhov tseeb, tsuas yog rau qee yam los txo nws cov khawb av. Qhov kev tshawb fawb tob rau hauv qhov ua rau pom yooj yim saum npoo ntawm cov yeeb yaj kiab thiab cov kev tsis zoo ntawm kev ua yeeb yam zoo rau cov yeeb yaj kiab hauv BOPP.
