Raw Material Standards
Cov khoom siv tseem ceeb rau kev hloov pauv FIBCs (Flexible Intermediate Bulk Containers) yog cov xov paj yas xws li polypropylene (PP) lossis polyethylene (PE). Cov khoom siv raw yuav tsum muaj lub cev zoo, xws li lub zog txaus, toughness, thiab kev laus ua haujlwm. Lub purity ntawm cov ntaub ntawv raw yuav tsum siab, thiab lawv yuav tsum tsis txhob muaj ntau impurities, txwv tsis pub nws yuav cuam tshuam rau tag nrho cov zoo ntawm FIBC. Piv txwv li, impurities yuav ua rau cov xov paj tiaj tus tawg thaum lub sij hawm xaws, txo lub zog ntawm FIBC.
Weaving Txheej Txheem
Cov txheej txheem weaving ncaj qha cuam tshuam rau lub zog thiab cov tsos ntawm FIBC. Lub weaving ceev yuav tsum ua raws li cov qauv tsim nyog. Feem ntau, qhov ntom ntom ntawm 100mm × 100mm yuav tsum ncav cuag tus nqi kom ntseeg tau tias FIBC muaj peev xwm txaus-cov kabmob. Lub warp thiab weft threads yuav tsum zoo ib yam thiab nruj, tsis muaj teeb meem xws li tsis muaj warp los yog weft threads, los yog hla stitches. Tsis tas li ntawd, qhov saum npoo ntawm lub hnab woven yuav tsum tiaj tus, tsis muaj qhov pom tseeb wrinkles lossis puas.
Sewing Standards
Kev xaws zoo ntawm FIBC kuj tseem ceeb heev. Siab -lub zog, puas ntsoog- cov ntaub ntawv tiv taus xws li polyester xov yuav tsum tau siv los xaws. Lub plooj sib nrug yuav tsum tsis sib xws, thiab tus lej ntawm stitches ib 100 hli yuav tsum feem ntau nyob rau hauv qhov kev teev tseg. Lub stitching yuav tsum muaj kev ruaj ntseg, tshwj xeeb tshaj yog kev sib txuas ntawm lub lifting straps thiab lub hnab lub cev, uas yuav tsum muaj peev xwm tiv taus ib tug tensile quab yuam los tiv thaiv kev tawg thaum lub sij hawm nqa.
Cov qauv kev ua tau zoo ntawm lub cev
Saj zawg zog intermediary hnab (FIBCs) yuav tsum muaj qee yam khoom ntawm lub cev. Piv txwv li, lawv lub zog tensile yuav tsum ua tau raws li qhov yuav tsum tau ua, ua rau lawv tuaj yeem tiv taus qhov hnyav ntawm cov khoom thauj khoom tsis tawg. Kua muag kuj yog ib qho tseem ceeb qhia; Thaum lub sij hawm thauj khoom, tshem tawm, thiab kev thauj mus los, FIBCs yuav raug khawb los ntawm cov khoom ntse, thiab tsim kua muag zoo tuaj yeem tiv thaiv kev puas tsuaj. Tsis tas li ntawd, FIBCs yuav tsum muaj qee qhov kev tiv thaiv UV kom hloov mus rau qhov chaw sib txawv thiab kev thauj mus los.
