Tshuav qhov cuab yeej nyuaj rau kev sib txuas nrog BOPP film uas tsis txhawb nqa

Yog li cas qhov ntsuas ntawm qhov ntsuas yuav tshwm sim ntau dua li koj xav tau

Cov ntawv uas muaj qhov ntsuas zoo rau lub tshuab yuav tshwm sim ntau dua li koj xav tau thaum lawv pib mus rau hauv qhov kev sib xyaw. Qhov ntsuas, qhov ntsuas rau cov ntawv hauv, qhov ntsuas los ntawm cov neeg siv, thiab qhov ntsuas los ntawm qhov cua txias yog qhov ua rau muaj qhov ntsuas rau cov ntawv uas tsis muaj kev zaum. Phaj BOPP tsis muaj ntawv qhia yuav pab tshem qhov teeb meem no los ntawm kev xa cov ntaub ntawv nyob rau hauv uas tsis muaj qhov ntsuas thiab tsis muaj qhov ntsuas rau cov ntawv hauv. Qhov kev ua yuav zoo dua li qhov kev ua tshwj xeeb rau "phaj zoo dua", thiab kev paub qhov kev ua yuav pab koj xa cov ntawv uas zoo rau qhov kev siv.

Qhov Chemistry ntawm Cov Lus Qhia Tshuaj Ua Rau Lub Tshuaj Tshiab Ua Rau Lub Tshuaj Tshiab

Kev tiv thaiv rau kev pov tseg ntawm cov BOPP films tiv thaiv pov tseg tuaj yeem los ntawm lub tshuaj qhia tshuaj ntawm qhov saum toj, uas feeb tshaj plaws yog lub tshuaj qhia tshuaj uas tau muab siv rau qhov saum toj ntawm lub film polypropylene uas tau muab kawm dua li cov lwm yam, thiab muab siv rau qhov saum toj ntawm lub film polypropylene uas tau muab kawm dua li cov lwm yam. Qhov ntsuas ntawm qhov tshuaj qhia tshuaj no feeb tshaj plaws yog muab ntsuas los ntawm qhov ntsuas pencil hardness uas tau muab qhia hauv ASTM D3363, thiab cov tshuaj qhia tshuaj tiv thaiv pov tseg uas muaj qhov zoo feeb tshaj plaws yog 2H lossis siab dua. Thaum qhov ntsuas no, qhov pov tseg uas muaj los ntawm qhov rooj ntawm lub ntawv, qhov ntaub ntawv, thiab cov khoom siv rau kev kho cov khoom tsis tuaj yeem ua rau muaj qhov pov tseg uas tuaj yeem pom tau.

Qhov system adhesive ntawm qhov tom qab yog qhov uas cov BOPP film tiv thaiv pov tseg sib sau rau lub substrate uas muaj cov lus qhia. Qhov no sib sau rau qhov tswv yim thermal bonding uas muaj nyob rau hauv cov BOPP uas tau muab qhia lawm, uas yog qhov tias cov khoom siv lamination uas muaj nyob lawm tuaj yeem siv cov film no tsis txhob muab suav rau qhov kev hloov.

Qhov Paj Nkaus Ntawm Kev Siv Nyob Hauv Txoj Kev Ntawv

Qhov ntsiab lus ntawm qhov coefficient of friction yog qhov tseem ceeb dua li cov neeg xa tuaj yuav xav rau qhov kawg. Qhov coefficient of friction (CoF) tsis siab yog qhov uas cov ntawv los ntawm lub tshuab yuav tswi tsis tshuaj thiab tsis nyha, uas txhawj rau qhov tshuaj kho rau cov ntawv hauv lub tshuab thiab ua rau cov khoom sib tshuaj thiab cov khoom sib tshuaj tau zoo dua.

Thaum qhov kho tau los ua qhov teeb meem rau kev lag luam

Cov ntawv uas cov ntaub ntawv BOPP tiv thaum qhov tsis tuaj noj tau qhov ntau dua yog yuav pom zoo rau lub cim thib peb uas muaj kev txhaum. Cov ntaub ntawv ntawm cov ntawv, cov ntaub ntawv uas yuav tshem tawm, cov ntaub ntawv rau cov khoom hais rau hauv tsev kho, thiab cov khoom uas muaj ntau lub rooj uas yuav tshem tawm tau ntau dua rau hauv qhov kev sib koom ua haujlwm. Ib tug neeg uas ua cov ntaub ntawv rau cov khoom kho nyob rau hauv lub xov tooj tom qab ntawm China tau pom qhov teeb meem no los ntawm kev ua haujlwm: qhov kev xaiv thib rau ua cov ntaub ntawv BOPP uas muaj qhov ntxhiab, thiab rau hauv ob lub hlis thaum cov khoom tau txog rau cov neeg siv khoom, cov ntawv uas muaj cov lus nyeem tau pom tau muaj cov qhov tshem tawm los ntawm kev sib koom ua haujlwm. Thaum muab cov ntaub ntawv uas tiv thaum qhov tsis tuaj noj tau xaiv los ua dua, qhov teeb meem tau hlub, thiab cov neeg siv khoom tau muab cov khoom thib dua mus rau qhov kev xaiv tshiab.

Qhov kev muab ntxiv tsis yog ib yam uas yuav tsum muab ua. Cov ntaub ntawv uas yuav siv ib zaug lossis yuav siv rau lub sijhawm short-shelf-life tsis yuav tshwm tau qhov ntau dua. Qhov kev tiv thaum qhov tsis tuaj noj tau muab siv thaum cov khoom yuav tau siv ntau zaug lossis tau muab xaiv rau lub sijhawm ntev.

Kev Pab Tsis Qhia Txog Kev Siv Lub Tshuab

Siv lub tshuab BOPP uas tsis muaj kev ntsuas qhov cim rau hauv lub tshuab kub yuav tsum qhia txog qhov cim ntawm qhov kub thiab qhov cim ntawm lub tshuab kub ntau dua li qhov tshuab uas tau muaj kev pab tsis qhia lawm. Cov khoom uas nyob hauv qhov ntim ntawm qhov tshuab yog qhov tsis muaj kev sib thaj ntau rau qhov kub uas ntxiv, uas yuav ua rau qhov ntim ntawm qhov tshuab muaj kev ntsuas qhov cim. Ntau tus tsim khoom qhia tias qhov kub uas yuav tsum siv yog plus los sis minus 5°C ntawm qhov kub uas qhia, thiab qhov kub uas yuav tsum siv yog qhov tseem ceeb dua thaum qhov kub ntawm lub tsev tsim khoom muaj kev ntsuas qhov cim.

Qhov kub ntawm cov rool ntawm lub tshuab kub yog qhov xwm txheej uas tsis muaj kev qhia tias nws yog qhov tseem ceeb. Qhov cim uas nyob hauv cov rool ntawm lub tshuab kub yuav tshuav mus rau hauv qhov ntim ntawm lub tshuab thaum muaj qhov kub thiab qhov cim, thiab cov khoom uas tsis muaj kev ntsuas qhov cim yuav ua rau qhov cim uas tshuav mus rau hauv qhov ntim ntawm lub tshuab muaj kev ntsuas qhov cim ntau dua li qhov tshuab uas muaj kev ntsuas qhov cim lossis qhov tshuab uas muaj kev ntsuas qhov cim zoo. Qhov kev qhia tias yuav tsum saib xyuam cov rool ntawm lub tshuab kub thaum muaj kev sib thaj yuav pab tshem qhov no los ntawm kev pab tsis qhia.

Txheeb xyuam cov neeg siv khoom rau qhov kev qhia tias cov khoom tsis muaj kev ntsuas qhov cim

Kev sib piv ntawm cov thawv tswv yim rau kev tiv thaiv qhov tsis zoo ntawm cov ntaub ntawv yog sib txawv heev, thiab tsis yog tag nrho cov lus hais yog muaj kev txhawb kom paub tias yog qhov tseeb. Thaum peb xav txheeb xyuas cov thawv tswv yim rau cov ntaub ntawv, peb yuav tsum nug rau cov lus txhawb kom paub tias cov lus hais yog qhov tseeb los ntawm kev txheeb xyuas rau qhov ntau npaug ntawm cov ntaub ntawv (pencil hardness test) uas muaj kev txheeb xyuas raws li ASTM D3363 lossis ISO 15184, kom muaj kev txheeb xyuas tshwj xeeb. Kev txheeb xyuas yuav tsum tau ua nyob rau ntawm ntau qhov ntawm qhov ntev ntawm cov ntaub ntawv kom paub tias cov ntaub ntawv yog zoo ib yam, tsis yog nyob rau hauv qhov cim ntawm cov ntaub ntawv xwb.

Qhov kev txheeb xyuas tias cov ntaub ntawv yog zoo ib yam rau ntawm qhov ntev ntawm cov ntaub ntawv yog qhov uas sib txawv rau ntawm cov thawv tswv yim uas muaj kev txheeb xyuas rau kev tsim kho. Cov qhov ntau npaug ntawm cov ntaub ntawv uas yog ntau npaug dua yog yuav tsum tau txheeb xyuas rau ntawm cov qhov uas muaj kev sib thaj ntau, thiab yuav ua rau cov ntaub ntawv tsis zoo ib yam rau ntawm lub zog, uas yuav tsis tuaj yeem paub tias yog dab tsi yog qhov cuam tshuam rau qhov no yog tsis tau txheeb xyuas rau ntawm cov ntaub ntawv uas muaj kev txheeb xyuas.

Cov ntaub ntawv BOPP uas tiv thaiv qhov tsis zoo ntawm EKO yog qhov uas muaj kev nco ntsoom rau qhov kev txheeb xyuas tias cov ntaub ntawv yog zoo ib yam, uas muaj kev txheeb xyuas rau ntawm kev tsim kho uas muaj kev txheeb xyuas rau ntawm qhov ntev ntawm cov ntaub ntawv, tsis yog nyob rau ntawm cov qhov uas tau txheeb xyuas xwb.
