Daim ntawv thov ntawm nylon zaj duab xis hauv kev ntim khoom noj tsiaj

Hauv cov tebchaws sab hnub poob, "kev lag luam tsiaj" yog kev lag luam loj.Noj cov khoom noj tsiaj ua piv txwv, North America (feem ntau yog Tebchaws Meskas) yog cov neeg siv khoom lag luam loj tshaj plaws ntawm txhua yam khoom noj tsiaj, thiab nws kuj suav rau feem coob ntawm kev muag khoom.Western Europe yog cov neeg siv khoom lag luam ua lag luam rau tag nrho lwm yam khoom noj tsiaj, thiab qhov thib ob loj tshaj plaws cov neeg siv khoom lag luam rau dev thiab miv zaub mov.Ntawm lawv, txoj kev loj hlob ntawm tsiaj kev lag luam hauv Tebchaws Meskas thiab Nyij Pooj yog qhov tshwj xeeb.

Cov teeb meem uas nquag tshwm sim hauv kev ua lag luam tam sim no

Hauv Suav teb, ntau thiab ntau tus neeg muaj tsiaj.Nrog rau kev nce ntawm cov tsiaj, ntau cov kev lag luam muaj feem cuam tshuam tau tshwm sim nyob ib puag ncig kev lag luam tsiaj, xws li khoom noj tsiaj, khoom siv tsiaj, kev kho tsiaj tsiaj, kev lag luam tsiaj zoo nkauj, thiab lwm yam, uas yuav muaj kev lag luam dav dav.Kev ntim khoom noj tsiaj yuav dhau los ua ib qho chaw kub kub hauv kev ntim khoom yav tom ntej.

Noj cov khoom noj tsiaj xws li miv thiab dev ua piv txwv, cov khoom siv raw yog cov khoom siv nqaij.

Nws cov yam ntxwv muaj xws li ob yam hauv qab no:

1. Yuav kom tswj tau qhov saj ntawm cov khoom noj tsiaj, cov khoom xyaw yuav tsum tsis txhob ua kom mos dhau los yog hmoov thaum lub sij hawm tsim khoom.Nws yog ib qho tsim nyog los tswj lub toughness thiab brittleness ntawm nqaij, pob txha thiab ntses pob txha.Yog li ntawd, cov khoom noj tsiaj yog tus cwj pwm tsis zoo thiab muaj cov khoom ntse xws li cov pob txha thiab cov pob txha ntses.

2. Cov khoom noj tsiaj yog cov khoom noj uas muaj irradiated.Txhawm rau kom lub neej txee ntev, cov khoom noj tsiaj yuav tsum tau irradiated kom tsis muaj menyuam.Cov zaub mov irradiated yog hais txog cov khoom noj uas ua los ntawm irradiation nrog gamma rays uas ua los ntawm cobalt-60 thiab cesium-137 los yog cov kab hluav taws xob qis dua 10MeV uas ua los ntawm electron accelerators, suav nrog cov khoom noj khoom haus irradiated thiab cov khoom ua tiav.

Tam sim no, irradiation technology yog dav siv nyob rau hauv ntau lub teb chaws los xyuas kom meej cov zaub mov muaj kev ruaj ntseg thiab ntev lub neej txee, thiab tau lees paub los ntawm ntau thiab ntau cov neeg siv khoom.zoo li cov tub yees uas tsis muaj kub, kub-kub thiab tshuaj kho mob, cov cuab yeej no yuav tshem tawm cov kab mob. uas ua rau cov zaub mov tsis zoo thiab cov kab mob ua rau cov khoom noj hauv cov zaub mov.Nyob rau hauv ntim khoom noj, hluav taws xob kuj yog ib txoj hauv kev zoo los ua kom lub neej txee ntawm cov zaub mov.

Hauv aseptic ntim tshuab, txoj kev ua kom tsis muaj menyuam rau cov khoom ntim muaj xws li ultraviolet sterilization, chemical method thiab ultraviolet ua kom tsis muaj menyuam, infrared sterilization, ionizing hluav taws xob thiab lub teeb pulses.Thaum cov khoom ntim tsis tuaj yeem dhau lub zog thermal los yog dhau los ntawm Ionizing hluav taws xob yog txoj kev ua kom tsis muaj menyuam txias zoo rau tshuaj tua kab mob thiab ua kom tsis muaj menyuam.

Tam sim no, cov tsiaj ntim khoom ntim hauv Suav lag luam feem ntau siv cov txheej txheem ntim zipper hnab peb sab.Txhawm rau txhim kho cov nyhuv txee thiab thaiv kev ua haujlwm, feem ntau cov khoom siv ntim khoom siv hauv tsev siv VMPET lossis AL raws li txheej txheej thaiv;

Cov teeb meem ntawm kev ntim khoom noj tsiaj hauv Suav teb suav nrog cov hauv qab no:

1. VMPET los yog Al yog siv los ua cov txheej txheem barrier, tab sis cov khoom tsis tuaj yeem pom ncaj qha, uas txwv cov txee tso saib cov nyhuv ntawm cov khoom;

2 Raws li cov khoom lag luam yog cov pob txha, pob txha ntses thiab lwm yam khoom, lub hnab ntim tau yooj yim rau punctured, ua rau muaj teeb meem zoo.

3 Lub smoothness ntawm lub hnab ntim tsis zoo, thiab qhov qhib yog tsis zoo nyob rau hauv cov txheej txheem ntau lawm, thiab cov efficiency ntau lawm yog tsawg.Nyob rau tib lub sijhawm, nws tseem yuav txo qhov kev siv ntawm lub hnab ntim khoom thiab nce tus nqi.

4 Tom qab irradiation, tag nrho txhua yam khoom ntawm lub hnab poob.

Tsim lub tswv yim ntawm cov qauv sib xyaw rau kev ntim khoom noj tsiaj

Hauv kev tsim khoom tiag tiag, irradiation tsis muaj kev cuam tshuam rau cov khoom ntawm iav thiab cov thawv hlau, tab sis nws tuaj yeem txo qhov kev hloov pauv thiab cov khoom siv kho tshuab ntawm cov yas.Yog li ntawd, nyob rau hauv cov txheej txheem tsim, yog tias tsis muaj cov qauv tsim nyog, lub hnab ntim tau yooj yim rau punctured thiab lub cev thiab cov khoom siv ntawm lub hnab raug txo.Yog li ntawd, nws yog qhov tseem ceeb heev los kawm txog cov qauv sib xyaw tshwj xeeb kom hloov mus rau qhov cuam tshuam ntawm irradiation ntawm cov khoom ntawm cov yas.

Kev ntim khoom noj tsiaj yuav tsum ua tau raws li cov cai hauv qab no thaum lub sijhawm ntim tiag tiag, kev thauj mus los, cia thiab siv:

1. Kev ua haujlwm zoo barrier

Cov khoom ntawm lub pob yog cov khoom noj tsiaj, uas yuav tsum muaj peev xwm ua tau raws li qhov kev lees paub zoo ntawm cov khoom, tswj qhov zoo thiab tsw ntawm cov khoom, thiab muaj lub neej txee zoo.

2. Zoo puncture kuj

Nws muaj cov khoom ntse xws li cov pob txha thiab cov pob txha ntses.Txhawm rau kom ntseeg tau tias lub hnab tsis punctured, nws yuav tsum muaj qhov zoo tiv thaiv.

3. Pom tau zoo

Koj tuaj yeem pom cov khoom ncaj qha los ntawm lub pob kom nyiam cov neeg siv khoom nyiam.

4. Zoo nruj

Cov khoom noj tsiaj no yog ntim nrog cov zipper sawv ntsug, yog li cov khoom ntim khoom muaj qhov nruj zoo thiab tuaj yeem txhim kho lub txee ntawm cov khoom.

5. Kev tiv thaiv hluav taws xob zoo

Tom qab irradiation, nws tseem tuaj yeem tuav cov khoom zoo.

Piv txwv ntawm kev xaiv cov qauv

Txhawm rau ua kom tau raws li cov kev xav tau saum toj no rau kev ntim khoom noj tsiaj, peb xav tias cov qauv hauv qab no tuaj yeem siv tau:

Nruab nrab txheej: BOPA zaj duab xis los yog EHA siab barrier zaj duab xis nrog ntau dua oxygen kuj

BOPA nylon yog polyamide, uas muaj lub zog zoo heev, toughness, tensile zog, elongation thiab hnav tsis kam.Nylon raug xaiv vim nws muaj lub cev zoo thiab txhua yam khoom.Tom qab kev sib xyaw ua ke, nws tuaj yeem txhim kho qhov puncture tsis kam, cuam tshuam thiab lwm yam khoom ntawm cov khoom, thiab tuaj yeem tiv thaiv cov ntsiab lus zoo.Kev pom zoo: Changsu BOPA Ultrany.

EHA muaj ultra-high oxygen tsis kam (oxygen transmittance OTR tsawg li 2cc / ㎡ hnub · ATM), uas tuaj yeem ua tiav cov tshuaj tsw qab zoo heev;Nws rubbing kuj, tensile kuj thiab zoo heev ua raws li lub zog zoo heev txo lub hnab tawg tus nqi;Thiab nws muaj peev xwm ua tau siab transparency thiab zoo heev printing nyhuv;Tsis tas li ntawd, nws kuj yog ib qho khoom siv zoo ib puag ncig uas yuav tsis tsim cov pa phem thaum hlawv.Kev pom zoo: Changsu Supamid EHA tshiab locking zaj duab xis.

Sab hauv txheej: PE zaj duab xis nrog cov qauv zoo dua

Xav txog kev nyab xeeb thiab kev nyiam huv ntawm cov zaub mov tsiaj, cov khoom no siv cov txheej txheem tsim khoom hnyav-dawb.Txawm li cas los xij, cov txheej txheem tsim khoom hnyav-dawb yuav muaj teeb meem ntawm kev sib txhuam coefficient siab thiab kev qhib tsis zoo.Yog li ntawd, txhawm rau txhim kho cov cuab yeej hloov kho ntawm PE, kev tsim kho, kev sib tsoo thiab hluav taws xob tiv thaiv ntawm lub hnab lub cev yuav tsum tau xav txog.Cov mis PE tuaj yeem txhim kho kom nws muaj cov cuab yeej siv tau zoo dua qub, tawv tawv thiab puncture tsis kam.

BOPA nylon yog polyamide, uas muaj zog crystallinity, siab melting point thiab kev ua tau zoo heev.Zoo toughness, tensile zog thiab cuam tshuam lub zog yog ho zoo dua li cov yas zaj duab xis.Raws li cov txheej txheem nruab nrab hauv qhov project no, nws tuaj yeem txhim kho qhov puncture tsis kam ntawm PET ntim los tiv thaiv cov khoom ntse xws li cov pob txha ntses los ntawm punctureing zaj duab xis.Tsis tas li ntawd, cov huab cua nruj ntawm nylon zoo dua li ntawm PE thiab PP, uas tuaj yeem txhim kho qhov kev ua tau zoo ntawm kev ntim khoom.Nyob rau tib lub sijhawm, nws muaj cov roj zoo, uas tuaj yeem tiv taus cov roj stain thaum ntim cov khoom noj tsiaj ntawm cov khoom noj nqaij, kom tsis txhob delamination ntawm ntim zaj duab xis thiab poob ntawm tev lub zog.

Lub sijhawm ntxiv rau cov khoom noj tsiaj tau los txog, thov tsis txhob tos ntxiv lawm!Cia ChangsuPEB filmthiabSaib movietiv thaiv tsiaj noj.
