Kev pom zoo ntawm Porosity, Particulate Contamination, thiab Txheej Txheej Txheej Txheem Zoo
Hauv kev ntim khoom siv kho mob tsis muaj menyuam, xaiv cov ntaub npog tsim nyog yog qhov tseem ceeb los ua kom cov neeg mob muaj kev nyab xeeb thiab tswj xyuas cov kab mob microbial uas muaj zog. DuPont ™ Tyvek® tau txais kev lees paub dav dav raws li tus qauv kub rau kev ntim khoom kho mob vim nws lub zog tshwj xeeb, tsim kua muag, thiab microbial barrier zog. Txawm li cas los xij, thaum Tyvek® siv los ua lub hau npog (piv txwv li, Tyvek® 1073B, 1059B, lossis 2FS), kev xaiv txheej txheej tshuab thiab cov txheej txheem thov ua lub luag haujlwm tseem ceeb hauv kev txiav txim siab sealing kev ua tau zoo, ua pa, thiab muaj kev pheej hmoo ntawm kev sib kis.
Txoj Cai Tseem Ceeb Tseem Ceeb: Ua tsis taus pa vs
Cov khoom siv kho mob tau ntim rau hauv cov tais tawv tawv lossis daim ntawv -fill-foob (FFS) cov tshuab feem ntau raug ua kom tsis muaj roj, xws li Ethylene Oxide (EO). Qhov no yuav tsum muaj qib siab ntawm breathability nyob rau hauv cov ntaub ntawv lidding tso cai rau kev nkag mus rau cov pa roj thiab khiav ceev ceev yam tsis muaj lub tsev txaus ntshai sib txawv uas yuav cuam tshuam cov pob seals.
Ntsiab Metric - Gurley Porosity: Uncoated Tyvek® ib txwm ua rau muaj kev ua pa zoo heev. Kev sib koom ua ke ntawm cov dot siab heev- qauv kub- cov txheej txheem yaj txheej (xws li Pupack™) khaws cov cwj pwm no. Kev ntsuam xyuas qhia tau hais tias Gurley Porosity ntawm 30.4 sec / 100cc rau coated Tyvek® 1073B, uas zoo sib xws rau 22 sec / 100cc benchmark ntawm raw, uncoated Tyvek®.
Mitigating Particulate Contamination: Kub- Melt vs. Dej- Raws li Txheej Txheej
Cov kab mob sib kis ua rau muaj kev pheej hmoo rau qhov chaw kho mob tseem ceeb yog qhov nyuaj rau cov dej ib txwm siv -raws li lossis hnyav- raws li cov nplaum nplaum. Thaum lub sij hawm tev thiab qhib cov txheej txheem, cov txheej txheem ib txwm ua rau cov kua muag fiber ntau los yog cov nplaum tawg, tso cov microscopic particulates.
Kev soj ntsuam sib piv qhia tau hais tias cov kuab tshuaj siab tshaj - dawb kub- cov txheej txheem yaj ua rau txo qis cov kab mob sib kis thoob plaws txhua qhov loj me me thaum piv rau cov qauv dej- raws li lwm txoj hauv kev:

Txheej Txheej Txheej Txheem Txheej Txheem: Rotary Engraved Dot Pattern
Txhawm rau kom ua tiav qhov siab tshaj plaws nplaum anchorage yam tsis muaj kev sib khi tawm ntawm qhov ntxeem tau ntawm Tyvek®, cov txheej txheem txheej txheej txheej txheem siv lub tshuab ua teb engraved rau cov menyuam. Txoj kev no nta:
100% Solids, Solvent-Dawb Formulation: Ib tug kiag li tsis yog - tshuaj lom chemistry uas tshem tawm cov tshuaj lom neeg txaus ntshai los yog volatile organic compound (VOC) residues.
High -Tsub Kub Anchoring: Ua haujlwm ntawm qhov kub siab, cov nplaum nplaum ua ib qho khoom siv thauj tog rau nkoj nrog Tyvek® nto fibers yam tsis tau ua kom thermal shrinkage lossis degradation ntawm cov substrate.
Cohesive Peeling Mechanics: Cov dot- qauv geometry muab kev ua kom zoo, huv si tev vector. Thaum qhib, nws qhia tau hais tias kev sib koom ua ke tsis ua haujlwm tsis zoo hauv cov nplaum sib txuas es tsis yog delaminating lub substrate, muab qhov pom tseeb ntawm kev kuaj xyuas kev sib khi.

Kev Ua Raws Cai thiab Ntev - Lub Sij Hawm Stability
Kev ntim khoom kho mob yuav tsum tiv taus cov kev ntxhov siab ntawm lub cev thiab lub txee ntev ntev - lub neej yuav tsum tau ua. Thib peb-kev xeem neeg ua pov thawj pom zoo ua raws li qhov tseem ceeb ntawm biocompatibility thiab endurance qauv:
Cov kab mob Endotoxins & Cytotoxicity: dhau kev soj ntsuam lom neeg, suav nrogHauv VitroCytotoxicity Test, Skin Sensitization Test, thiab Skin Irritation Test, paub meej tias tsis yog tag nrho - toxicity.
Environmental Resilience: Kev ua haujlwm siab rau cov dej noo thiab tiv thaiv -condensation ua kom lub ntim khaws cov qauv kev ncaj ncees thaum lub sij hawm siab -cov av noo shipping profiles. Enhanced UV- raug tiv thaiv tiv thaiv cov qauv polymer los ntawm ua ntej -sterilization ib puag ncig degradation.
Accelerated Aging Verification: Cov txheej txheem pov thawj pob ntawv pov thawj paub meej tias lub foob lub zog thiab cov khoom thaiv kab mob microbial nyob ruaj khov dhau qhov qhov rais nrawm nrawm sib npaug rau 5 xyoos.
