Txuas ncaj qha tshav ntuj inflicts irreversible loj puas tsuaj rauPP Ntim Hnabthiab cuam tshuam tsis zoo rau kev ua haujlwm ntawm cov khoom siv, lub peev xwm thauj khoom, kev pabcuam lub neej thiab kev nyab xeeb ntawm kev ua haujlwm tag nrho. Txawm tias PP Bulk Bags haum nrog UV-stabilized coatings yuav maj mam degrade nyob rau hauv lub sij hawm qhib-air raug; zoo tib yam uas tsis yog-UV-stabilised PP Bulk Bags deteriorate ntawm tus nqi sai heev. Cov txheej txheem kev puas tsuaj ntsig txog thiab cov teeb meem tshwm sim tau piav qhia hauv qab no.
Ua ntej, ultraviolet hluav taws xob tawg tawg polypropylene molecular chains thiab pib irreversible photochemical aging. Polypropylene polymer chains nthuav tawm siab rhiab heev rau hnub ci ultraviolet rays. Lub sij hawm ntev irradiation muab lub zog uas ua rau cov kab mob siab molecular-weight polymer chains thiab hloov cov khoom siv micro-level los ntawm photo-oxidative aging tshwm sim. Saj zawg zog, densely woven fibers degrade, molecular kev ua ub no thiab tag nrho cov khoom stability deteriorates. Qhov kev puas tsuaj laus no tsis tuaj yeem thim rov qab los ntawm kev tu lossis tu niaj hnub thiab sawv cev rau ib qho ntawm cov ua rau PP Bulk Bag kawg ntawm lub neej so haujlwm.
Qhov thib ob, kev poob qis ntawm lub cev ua haujlwm zoo sib xws nrog kev pom pom tseeb thiab cov ntaub ntawv degradation. Lub hnub ci raug rau lub sij hawm luv luv ua rau tsis muaj xim, xim dawb, yellowing thiab patchy mottling thoob plaws lub hnab, ua rau pom cov cim ceeb toom ntxov ntawm kev laus tsis tu ncua. Tom qab lub hnub raug lub hnub ntev, cov ntaub npuag poob nws qhov yooj yim thiab tig tawv, qhuav thiab nkig nrog qhov ntxhib ntxhib ntxhib los mos. Woven fibers loosen, phua thiab shed fine fragments. Stitching threads kuj dhau los ua nkig, ua rau hla cov stitches thiab xoob seam pob qij txha uas ua rau tag nrho cov qauv kev ncaj ncees.
Thib peb, core load-bearing kev nyab xeeb kev ua haujlwm tsis zoo zuj zus thiab kev nyab xeeb ntawm qhov chaw nce ntxiv. Lub peev xwm thauj khoom, tsim kua muag ua haujlwm thiab lub zog tensile ntawm PP Bulk Bags cia siab rau qhov muaj zog ntawm cov khoom siv fiber ntau. Thaum muaj hnub nyoog, fibers qhia tau zoo heev txo lub zog tensile nrog rau kev puas tsuaj loj hauv kev puas tsuaj thiab tsim kua muag. Cov hnab ntim khoom qub tuaj yeem txhawb nqa tons ntawm cov khoom thauj tuaj yeem tawg nyob rau hauv lub teeb rub lossis compressive quab yuam. Thaum lub sij hawm txhaws, hoisting thiab hloov khoom siv, ntaub tawg, seam tsis ua hauj lwm thiab lifting-loop puas yuav tshwm sim. Cov kev ua tsis tiav no ua rau cov khoom spillage, ua haujlwm ntawm qhov chaw sib kis, khoom siv puas tsuaj thiab ua rau tus kheej raug mob hnyav.
Thib plaub, kev siv lub neej ua haujlwm tau cog lus tseem ceeb thiab tag nrho cov nqi ua haujlwm tau nce. Kev khaws cia kom raug, ntxoov ntxoo PP Bulk Bags tuaj yeem rov qab siv ntau zaus nrog kev pab cuam lub neej ntawm 1-3 xyoos. Lub hnab tsis tu ncua tawm sab nraum zoov ua rau muaj kev laus loj hauv 1-3 lub hlis thiab ua haujlwm tsis zoo hauv ib nrab xyoo. Kev hloov ntau zaus nce kev siv nyiaj ntawm cov khoom ntim khoom. Hnub nyoog PP Bulk Bags xa cov kev ua haujlwm tsis ruaj khov thiab tuaj yeem raug kev cia siab tsis ua haujlwm nruab nrab, cuam tshuam kev ua haujlwm ntau lawm thiab cov sijhawm hloov khoom siv.
Hauv cov ntsiab lus, lub sijhawm ntev uas tsis muaj kev tiv thaiv ncaj qha tshav ntuj yuav tsum zam rau PP Bulk Bags. Siv tarpaulin npog thaum lub sijhawm ua haujlwm sab nraum zoov ib ntus thiab hloov lub hnab kom txias qhov chaw sab hauv tsev sai sai thaum ua haujlwm tiav. Tiv thaiv ultraviolet irradiation slows cov khoom aging, khaws cia cov neeg kho tshuab kev ua tau zoo, ncua kev pab cuam lub neej thiab guarantees kev nyab xeeb chaw ua hauj lwm.
