Lub hnab valve yog dab tsi?
Lub Hnab Valve (tseem hu ua Valve Sack) yog ib hom kev lag luam ntim hnab ntim khoom tshwj xeebfilling spout los yog "valve". Nws tus yam ntxwv txhais yog tias lub hnab muajtsis muaj lub qhov ncauj qhib. Hloov chaw, ib qho - txoj kev lub tes tsho tubular, lub valve, tau muab tso rau hauv lub hnab lub ces kaum lossis sab saum toj.
- Nws ua haujlwm li cas:Thaum lub sij hawm sau, lub nozzle ntawm lub tshuab filling yog muab tso rau hauv lub valve. Cov khoom (piv txwv li, cement, hmoov) raug thawb rau hauv lub hnab los ntawm huab cua siab lossis lub ntiajteb txawj nqus. Thaum lub nozzle yog retracted, lub siab los ntawm cov khoom ntim khoom ua rau lub puab flaps los yog folds ntawm lub valve kaw cia, sealing lub hnab. Qhov kev tsim no ua tiav cov plua plav zoo- ntim thiab tuav tsis pub dawb.
- Cov txiaj ntsig tseem ceeb:
Plua plav-Free & Clean: Txo cov khoom poob thiab ib puag ncig kev sib kis.
Moisture & Sift-Cov pov thawj: Cov foob zoo heev tiv thaiv hygroscopic lossis hmoov zoo.
Kev Ua Haujlwm Siab: Ua kom muaj kev ua haujlwm siab, siab - nrawm puv kab; tsis tas yuav xaws los yog khi lub hnab lub qhov ncauj.
Superior Stackability: Pav ca, duab plaub kom ruaj khov palletizing thiab cia.
Lub Valve Hnab Manufacturing txheej txheem ntawm PP Woven khoom
* Kauj Ruam 1: Raw Material Preparation, Printing & Lamination
Base Fabric: Cov yob loj ntawm PP woven npuag yog thauj mus rau cov kab ntau lawm.
Flexographic Printing: Cov ntaub yog luam tawm nrog cov ntaub ntawv khoom, logos, thiab cov lus qhia tuav siv lub tshuab luam ntawv siab - ceev ceev.
Lamination / Txheej (rau cov hnab txhim kho): Txhawm rau txhim kho cov dej noo thaiv thiab foob lub zog, ib zaj duab xis yas (xws li BOPP lossis PE) feem ntau yog extrusion-coated los yog laminated rau ntawm daim ntaub. Qhov no tsim cov khoom sib xyaw.
** Kauj Ruam 2: Tube tsim
Cov ntaub ntawv luam tawm / coated yog precisely folded lengthwise thiab nws cov npoo yog kaw (feem ntau nrog ib tug nqaim lap seal) tsim ib tug nruam, ca raj.
*** Kauj Ruam 3: Lub hnab tsim los ntawm Cua Kub Vuam
① Hauv qab Sealing & Txiav: Lub raj nkag mus rau hauv lub hnab - ua tshuab, qhov twg cov cua kub melts cov txheej sab hauv, ua kom cov pa tawm - pov thawj weld thiab txiav ib lub hnab.
② Valve Daim Ntawv Thov & Kho: Lub tes tsho valve tau muab tso rau hauv lub hnab hauv qab thiab ruaj ntseg rau kev ua haujlwm zoo.
③ Gusset Forming & Folding: Lub hnab yog zoo li tus tsim sab gussets, ua kom qhov chaw ua haujlwm zoo tshaj plaws, tom qab ntawd ua kom zoo zoo rau ntim.
**** Kauj Ruam 4: Kev Tswj Xyuas Zoo & Ntim
Cov hnab tiav tau txais kev kuaj xyuas nruj rau kev luam tawm kom pom tseeb, weld kev ncaj ncees, thiab qhov loj me. Lawv suav, stacked, thiab compressed rau hauv bales, kom peb cov neeg muas zaub tau txais cov khoom zoo xwb.
