Thaum tsim cov hnab ziplock waterproof, cov txheej txheem tswj yog tus yuam sij kom ntseeg tau cov khoom zoo. Nov yog qee yam uas xav tau kev saib xyuas tshwj xeeb thaum lub sijhawm tsim khoom:
1. Kev xaiv cov khoom siv
Siv cov khoom zoo PE, LDPE lossis lwm yam khoom noj khoom haus los xyuas kom meej tias cov hnab ntim dej ziploc muaj qhov tawv zoo thiab sib khi.
Yog tias lub hnab yuav tsum tau pob tshab, xaiv cov khoom siv raw nrog cov pob tshab siab thiab tsis muaj impurities los xyuas kom meej qhov zoo nkauj ntawm cov khoom.
2. Ntau lawm kub
Kev tswj qhov kub thiab txias ntawm extruder yog qhov tseem ceeb heev. Kev kub siab dhau los yog qis dhau yuav cuam tshuam rau lub thickness thiab zoo ntawm zaj duab xis. Xyuas kom tseeb tias qhov ntsuas kub nyob hauv qhov tsim nyog, feem ntau ntawm 160-220 degrees Celsius, nyob ntawm cov khoom siv.
3. Self-sealing strip molding
Tus kheej-sealing sawb yog qhov tseem ceeb. Nws yog ib qho tsim nyog los xyuas kom meej tias qhov concave thiab convex nto ntawm lub foob yog tusyees molded thiab qhov tom yog raug. Ua tib zoo saib xyuas lub siab tswj lub sijhawm extrusion los tiv thaiv lub foob los ntawm nyias los yog tuab dhau thiab cuam tshuam rau kev siv.
4. Thickness uniformity
Xyuas kom lub uniformity ntawm lub hnab thickness los tiv thaiv qee qhov chaw los ntawm nyias thiab yooj yim tawg. Lub thickness yuav tsum tau tswj nyob rau hauv lub teev ntau yam kom ntseeg tau cov nyhuv waterproof.
5. Kev ntsuas kev ua haujlwm sealing
Tom qab txhua batch ntawm ntau lawm, cov khoom yuav tsum tau sim rau sealing kev ua tau zoo, xws li waterproofness, airtightness, thiab lwm yam. Xyuas kom cov pa tawm los ntawm inflating lub hnab thiab siv lub siab.
6. Kev ntsuas lub zog tensile
Waterproof ziplock hnab yuav tsum muaj lub zog tensile los xyuas kom meej thaum siv. Kev ntsuas tensile yuav tsum tau ua kom ntseeg tau tias lub hnab tsis yooj yim los tsim kua muag thaum raug lub zog tensile.
7. Ntau lawm ib puag ncig tswj
Khaws lub rhiav ntau lawm huv si, tshwj xeeb tshaj yog rau cov hnab ziplock siv rau cov hnab ntim khoom noj. Plua plav thiab lwm yam kuab paug yuav tsum raug zam thaum lub sij hawm tsim khoom los xyuas kom meej tias cov khoom ua tau raws li cov qauv kev nyiam huv.
8. txheej txheem luam ntawv
Yog tias lub hnab ntim dej ziploc muaj cov qauv luam tawm, kev tswj cov txheej txheem luam ntawv tseem ceeb heev. Siv tus cwj mem tus phooj ywg ib puag ncig kom tsis txhob pom qhov muag plooj thiab xim sib txawv ntawm cov qauv luam tawm, thiab xyuas kom meej tias cov ntawv luam tawm ruaj khov thiab tsis yooj yim rau ploj.
9. Txiav thiab ntim
Thaum txiav, xyuas kom meej tias lub hnab lub qhov ncauj zoo huv si thiab tsis muaj burrs kom tsis txhob cuam tshuam rau cov neeg siv khoom. Thaum ntim khoom, nws yuav tsum tau nqa tawm raws li cov neeg siv khoom xav tau kom paub meej qhov tseeb ntawm txhua lub hnab.
Los ntawm kev tswj cov txheej txheem nruj, cov hnab ntim dej ziplock tsis tuaj yeem tsuas muaj cov dej tsis zoo, tab sis kuj ua kom nws ntseeg tau thiab zoo nkauj hauv kev siv.
