Qhov cuam tshuam ntawm cov av noo ntawm Polypropylene PP Strapping Performance

Cov Lus Nug Humidity

Cov tsev khaws khoom hauv huab cua sov, thaj chaw ntug dej hiav txwv, thiab cov chaw cia txias txhua qhov sib tw: av noo. Rau cov kws tshaj lij ntim khoom cia siab rau PP strapping (polypropylene strapping) kom ruaj ntseg loads, ib lo lus nug tseem ceeb tshwm sim: cov av noo puas cuam tshuam rau kev ua tau zoo strapping? Cov lus teb yog nuanced. Polypropylene yog inherently noo noo-resistant piv rau hlau los yog ntuj fiber ntau lwm yam, tab sis nws tsis yog tag nrho tiv thaiv rau ib puag ncig tej yam kev mob.

Ntawm Jushuo Ntim , peb cov ntaub ntawv tsim tawm qhia tau hais tias cov teeb meem kev ua haujlwm ntawm cov av noo tsis tshua muaj tab sis tiv thaiv tsis tau. Kev nkag siab txog tias polypropylene cuam tshuam li cas nrog cov dej noo pab cov neeg yuav khoom xaiv cov kev qhia tshwj xeeb thiab kev khaws cia rau lawv qhov chaw ua haujlwm. Phau ntawv qhia no piav qhia txog kev tshawb fawb tom qab av noo thiab PP strapping kev ua tau zoo.

1. Polypropylene teb li cas rau cov dej noo

1.1 Polypropylene's Natural Moisture Resistance

Polypropylene yog ib qho uas tsis yog-polar hydrocarbon polymer, uas txhais tau hais tias nws tsis tshua muaj affinity rau dej molecules. Raws li cov ntaub ntawv tshawb fawb, polypropylene absorbs tsawg dua 0.01% noo noo los ntawm qhov hnyav raws li tus qauv, piv rau nylon (uas tuaj yeem nqus tau 2-8%) lossis ntuj fibers. Qhov kev nqus qis no yog vim li cas PP strapping tuav nws qhov ntev thiab lub zog hauv qhov chaw ntub dej zoo dua li lwm cov ntaub ntawv.

1.2 Yuav ua li cas tshwm sim ntawm High Humidity

Thaum polypropylene absorbs me ntsis noo noo, txuas ntxiv mus rau high humidity tseem tuaj yeem cuam tshuam PP strapping hauv txoj kev hloov maj mam. Raws li kev soj ntsuam kev lag luam:

• Deg noo noo : Condensation ntawm pluaj nto tuaj yeem ua rau muaj kev sib txhuam ib ntus

• Dimensional stability : Tsawg expansion lossis contraction tshwm sim

• Lub zog tensile : Tsis muaj qhov poob loj hauv cov xwm txheej ib txwm muaj

• Cia lub neej : Lub sij hawm ntev tuaj yeem cuam tshuam rau qhov pom

Jushuo Ntim cov ntaub ntawv kuaj pom tau tias PP strapping khaws ntau dua 98% ntawm nws lub zog tensile tom qab 30 hnub ntawm kev raug rau 90% cov av noo ntawm 30 ° C.

2. Kev ua tau zoo tiag tiag hauv ntiaj teb hauv qhov chaw ntub dej

2.1 Huab cua sov thiab ntug hiav txwv dej

Warehouses nyob rau hauv tropical thiab ntug dej hiav txwv cheeb tsam muaj cov av noo tsis tu ncua. Raws li kev txheeb xyuas kev lag luam ntim khoom, PP strapping ua tau zoo hauv cov cheeb tsam no vim tias nws qhov nqus dej tsis zoo. Cov kev txhawj xeeb tseem ceeb yog:

• Condensation ntawm pluaj nto : tuaj yeem cuam tshuam rau kev pub mis hauv tshuab tsis siv neeg

• Pwm thiab mildew : PP strapping tsis txhawb kev loj hlob lom

• Cov ntaub ntawv ntim khoom : Cartons yuav tsis muaj zog nyob rau hauv cov huab cua ntub, cuam tshuam rau kev ruaj ntseg load

2.2 Daim Ntawv Thov Txias Cia thiab Lub Freezer

Qhov chaw txias cia thiab lub freezer ib puag ncig muaj qhov sib txawv ntawm cov av noo. Raws li kev txheeb xyuas cov khoom lag luam txias, PP strapping tswj kev ua haujlwm hauv lub tub yees txias (-20 ° C thiab qis dua) vim tias nws tiv taus noo noo nqus thiab tsis ua rau qhov kub thiab txias. Qhov kev txhawj xeeb tseem ceeb yog condensation thaum tsiv ntawm thaj chaw kub.

2.3 Ntxuav-down thiab ntub ib puag ncig

Kev ua zaub mov thiab dej haus ua haujlwm feem ntau cuam tshuam nrog cov chaw ntxhua khaub ncaws uas muaj dej noo siab. Raws li cov qauv ntim khoom noj, PP strapping yog tsim rau cov cheeb tsam no vim nws tiv taus dej nqus thiab tsis corrode.

3. Tej yam uas cuam tshuam cov av noo cuam tshuam

3.1 Lub Sijhawm Tshaj Tawm

Raws li cov ntaub ntawv tshawb fawb, lub sijhawm ntawm cov av noo cuam tshuam rau PP strapping kev ua tau zoo:

3.2 Kub sib cuam tshuam

Cov av noo cuam tshuam yog cuam tshuam los ntawm qhov kub thiab txias. Raws li cov qauv kev tshawb fawb polymer, qhov kub siab dua ua rau muaj kev txav mus los ntawm molecular thiab tuaj yeem ua rau me ntsis nce ya raws diffusion. Txawm li cas los xij, rau polypropylene, cov nyhuv no tseem tsawg heev nyob rau hauv qhov chaw ua haujlwm kub.

3.3 Strap Formulation

Txawv PP strapping formulations yuav teb txawv rau cov av noo. Raws li kev tsim tshwj xeeb, cov khoom siv ntxiv thiab kev kho saum npoo tuaj yeem txhim kho cov dej noo tiv thaiv rau cov ntawv thov tshwj xeeb. Jushuo Ntim muab PP strapping nrog txhim kho noo noo tiv thaiv rau qhov xav tau ib puag ncig.

4. Cia thiab tuav cov kev coj ua zoo tshaj plaws

4.1 Cov lus pom zoo cia

Raws li cov lus qhia khaws cia, PP strapping yuav tsum tau muab khaws cia kom txo cov av noo:

4.2 Kev tuav hauv av noo

Raws li kev tuav cov kev coj ua zoo tshaj plaws, thaum ua haujlwm hauv qhov chaw ntub dej:

• Cia strapping kom acclimate rau sab hauv tsev ua ntej siv

• So cov condensation ntawm pluaj nto yog tias tsim nyog

• Siv embossed pluaj kom tuav tau zoo dua hauv cov dej noo

• Txheeb xyuas cov khoom siv rau kev ua haujlwm zoo ib yam

4.3 Lub neej txee

Raws li cov chaw tsim khoom tshwj xeeb, PP strapping muaj a Txee lub neej ntawm kwv yees li 2 xyoos nyob rau hauv kev cia khoom kom zoo. Hauv qhov chaw ntub dej, qhov no yuav raug txo kom tsawg yog tias tsis tswj xyuas qhov xwm txheej.

5. Sib piv cov khoom ua tau zoo hauv cov av noo

5.1 PP vs. PET hauv Humid Environments

Raws li kev txheeb xyuas kev lag luam, ob qho tib si PP thiab PET strapping ua tau zoo nyob rau hauv qhov chaw ntub dej, nrog PP muaj qhov nqus dej me ntsis.

5.2 PP vs Steel nyob rau hauv Humid Environments

Raws li kev txheeb xyuas ntim, PP strapping yog nyiam dua hlau hauv qhov chaw ntub dej vim nws tsis xeb lossis tawm xeb ntawm cov khoom.

Cov ntsiab lus

PP strapping ua tau zoo nyob rau hauv qhov chaw ntub dej vim tias polypropylene absorbs dej tsawg heev (tsawg dua 0.01% los ntawm qhov hnyav). Tsis zoo li cov hlau, uas xeb, lossis cov fibers ntuj, uas nqus cov dej noo tseem ceeb, PP strapping tuav nws qhov ntev, tensile lub zog, thiab kev ua haujlwm hauv cov av ntub. Raws li cov ntaub ntawv kuaj, PP strapping khaws ntau dua 98% ntawm nws lub zog tensile tom qab 30 hnub ntawm 90% txheeb ze av noo.

Rau kev ua tau zoo hauv qhov chaw ntub dej, khaws PP strapping hauv qhov txias, qhuav, qhov cua zoo kom deb ntawm tshav ntuj ncaj qha thiab hauv pem teb. Cia txoj hlua khi kom haum ua ntej siv rau hauv qhov chaw tswj qhov kub thiab txias. Siv embossed pluaj rau txhim kho tuav hauv cov dej noo.
