Flexible Intermediate Bulk Containers (FIBCs) - feem ntau hu ua cov hnab ntim loj lossis lub hnab loj - yog qhov tseem ceeb rau khaws cia thiab thauj cov khoom qhuav qhuav kom zoo. Ua los ntawm cov khoom siv ruaj khov polypropylene, cov hnab no txo cov nqi zog thiab ua kom yooj yim tuav piv rau cov ntim khoom ib txwm muaj. Hauv phau ntawv qhia no, peb rhuav tshem plaub lub ntsiab FIBC hom (A, B, C, thiab D) los pab koj xaiv lub hnab ntim khoom zoo rau koj daim ntawv thov tshwj xeeb.
FIBC Bags yog dab tsi?
FIBC hnab, tseem hu ua lub hnab loj lossis cov hnab ntim ntau, yog cov thawv ntim khoom tsim los tuav cov khoom lag luam qhuav qhuav. Lawv cov khoom siv polypropylene woven muaj cov nqi tsim nyog, lub teeb yuag tsis tau muaj zog rau kev lag luam xws li kev ua liaj ua teb, kev tsim kho, tshuaj, thiab kev ua zaub mov. Nyob ntawm tus qauv, FIBCs tuaj yeem muab cov qib sib txawv ntawm kev tiv thaiv electrostatic los xyuas kom muaj kev nyab xeeb ntawm cov chaw sib txawv.
Common FIBC Hnab Styles
Ua ntej dhia mus rau hauv hom electrostatic, nws yuav pab kom nkag siab txog cov qauv kev tsim kho ntawm ntau lub hnab:
- Circular FIBCs: Zoo tagnrho rau cov hmoov zoo thiab feem ntau siv tsis muaj liner.
- 4-Pab FIBCs: Ntau yam, nrog plaub cais vaj huam sib luag rau kev tuav zoo dua qub.
- U-Panel FIBCs: Economical thiab dav siv nyob rau hauv kev tsim kho thiab aggregates.
Plaub Hom FIBC Hnab rau Kev Tswj Xyuas Zoo
FIBCs yog categorized los ntawm lawv cov khoom electrostatic. Xaiv hom raug yog qhov tseem ceeb rau kev nyab xeeb thaum tuav cov khoom siv hluav taws xob. Hauv qab no peb nthuav dav hom A, Hom B, Hom C, thiab Hom D ntau lub hnab.
Hom A FIBC Hnab - Cov hnab ntim yooj yim rau cov khoom tsis-flammable
Hom A FIBCs yog tsim los ntawm woven polypropylene thiab lwm yam ntaub ntawv uas tsis yog-conductive. Lawv muab tsis muaj electrostatic tiv thaiv thiab yog li ntawd tsis tsim nyog rau qhov chaw uas muaj hluav taws kub los yog combustible. Kev sib txhuam ntawm lub hnab thiab nws cov ntsiab lus tuaj yeem tsim cov nqi zoo li qub, tab sis hauv qhov chaw tsis muaj kev phom sij, qhov no tsis muaj kev txhawj xeeb.
Kev siv ntau: Kev ua liaj ua teb (grains, noob), kev tsim kho (xuab zeb, gravel), thiab mining (minerals) qhov twg cov ntaub ntawv tsis-combustible thiab tsis muaj flammable vapors los yog hmoov av.
Yog tias koj lub chaw ua haujlwm tsuas yog cov khoom tsis muaj hluav taws kub, Hom A muab cov kev daws teeb meem ruaj khov. Rau ib puag ncig uas muaj kev pheej hmoo hluav taws kub, xav txog ib yam ntawm cov qib siab hauv qab no.
Hom B FIBC Hnab - Kev Tiv Thaiv Tawm Tsam Tshaj Tawm Txhuam Txhuam
Hom B FIBCs yog tsim los nrog cov ntaub ntawv uas muaj qhov tawg voltage hauv qab 4kV, uas tiv thaiv propagating txhuam tawm (PBD). Thaum lawv tseem tuaj yeem khaws cov nqi hluav taws xob zoo li qub, lawv cov kev tsim kho tshem tawm qhov kev pheej hmoo ntawm cov hluav taws xob hluav taws xob ntau los ntawm kev sib txhuam.
Cov hnab no muaj kev nyab xeeb rau kev siv thaum tsuas muaj cov plua plav me me uas muaj hluav taws kub-tshwj xeeb yog cov plua plav uas muaj lub zog hluav taws xob tsawg (MIE) ntau dua 3 mJ-thiab thaum tsis muaj cov pa taws lossis cov kuab tshuaj.
Hom kev lag luam: Kev ua tshuaj lom neeg, cov khoom xyaw zaub mov, thiab cov tshuaj uas cov khoom nws tus kheej tuaj yeem tsim cov plua plav tab sis ib puag ncig yog txwv tsis pub.
Hom C FIBC Hnab - Cov Khoom Siv Hluav Taws Xob & Groundable rau Flammable Ib puag ncig
Hom C FIBCs, tseem hu ua conductive bulk hnab, yog woven los ntawm non-conductive polypropylene nrog interwoven conductive threads (feem ntau yog ib daim phiaj qauv). Cov hnab no yuav tsum muaj av Thaum lub sij hawm sau thiab tso tawm kom muaj kev nyab xeeb dissipate hluav taws xob zoo li qub. Ib zaug hauv av, lawv tiv thaiv cov nplaim taws uas tuaj yeem ua rau cov hmoov hluav taws kub, vapors, gases, lossis cov kuab tshuaj.
Zoo tagnrho rau: Petrochemicals, mining, thiab txhua daim ntawv thov tuav cov hmoov hluav taws xob lossis cov kuab tshuaj uas yuav tsum tau tswj kom zoo li qub. Nco ntsoov: Lub hnab hom C tsuas yog muaj kev nyab xeeb thaum muaj av zoo; lawv yuav tsum tsis txhob siv nyob rau hauv high-voltage ib puag ncig uas grounding tsis tuaj yeem paub tseeb.
Hom D FIBC Hnab - Antistatic tsis muaj av
Hom D FIBCs (cov hnab antistatic) yog engineered nrog static-dissipative threads los yog coatings uas muaj kev ruaj ntseg tswj cov nqi zoo li qub tsis tas yuav tsum muaj av. Qhov no ua rau lawv yooj yim heev rau kev ua haujlwm uas cov khoom siv hauv av tsis zoo lossis qhov xav tau kev nyab xeeb ntxiv.
Cov ntaub tsim los tiv thaiv cov hluav taws kub hnyiab, ua rau lub hnab hom D haum rau ib puag ncig nrog cov pa taws, vapors, plua plav, lossis cov kuab tshuaj. Lawv tau siv dav hauv tshuaj, tshuaj, thiab ua zaub mov.
Nco tseg: Hom D hnab feem ntau kim dua li Hom A lossis B. Yog tias kev tswj zoo li qub tsis yog qhov kev txhawj xeeb, qhov kev xaiv qis dua yuav txaus.
Cov lus sib piv ceev: FIBC Hom ntawm ib sab
| Hom | Kev tiv thaiv zoo li qub | Yuav tsum muaj av av? | Hom kev siv |
| A | Tsis muaj | Tsis muaj | Cov ntaub ntawv tsis-flammable (xuab zeb, nplej) |
| B | Tiv thaiv kom propagating txhuam tawm | Tsis muaj | Cov plua plav me me (MIE> 3 mJ), tsis muaj cov pa taws |
| C | Conductive, dissipates static ntawm grounding | Yog lawm | Flammable hmoov, vapors, kuab tshuaj |
| D | Antistatic, dissipates yam tsis muaj grounding | Tsis muaj | Flammable ib puag ncig nrog cov pa roj / plua plav / cov kuab tshuaj |
Yuav Ua Li Cas Xaiv Txoj Cai FIBC rau Koj Txoj Haujlwm
Xaiv lub hnab ntim khoom kom raug yog nyob ntawm peb yam:
- Khoom siv flammability: Puas yog koj cov khoom lossis qhov chaw nyob ib puag ncig muaj peev xwm tawg tau?
- Ignition Source: Puas muaj electrostatic txaus ntshai los ntawm kev sau / tawm?
- Grounding peev xwm: Koj puas tuaj yeem txhim kho lub hnab ntim khoom (Hom C) lossis koj puas xav tau cov tshuaj uas muaj tus kheej (Hom D)?
Rau cov khoom qhuav uas tsis muaj kev phom sij, Hom A yog qhov zoo tshaj plaws. Rau kev pheej hmoo ntawm plua plav nkaus xwb, Hom B ntxiv ib txheej ntawm kev nyab xeeb. Thaum muaj cov pa taws los yog cov kuab tshuaj, xaiv hom C (nrog rau av) lossis Hom D (tsis muaj av).
