Ntim cov khoom yuav khoom | Yuav ua li cas xaiv cov khoom zoo yas hose

Kev xaiv thiab cov ntaub ntawv zoo yog tus yuam sij rau kev ua kom zoo ntawm cov hoses, uas yuav cuam tshuam ncaj qha rau kev ua thiab kev siv kawg ntawm hoses. Cov ntaub ntawv ntawm cov yas hoses muaj xws li polyethylene (rau lub raj lub cev thiab lub taub hau raj), polypropylene (tube cover), masterbatch, barrier resin, luam ntawv number case, kua roj vanish, thiab lwm yam. Yog li ntawd, kev xaiv ntawm ib yam khoom yuav cuam tshuam ncaj qha rau qhov zoo ntawm hose. Txawm li cas los xij, kev xaiv ntawm cov ntaub ntawv tseem nyob ntawm cov yam ntxwv xws li kev nyiam huv, kev tiv thaiv kev tiv thaiv (xws li oxygen, dej vapor, tshuaj tsw qab, thiab lwm yam), thiab tshuaj tiv thaiv.

Kev xaiv cov kav dej: Ua ntej, cov khoom siv yuav tsum tau ua raws li cov qauv kev nyiam huv, thiab cov khoom tsis zoo xws li cov hlau hnyav thiab cov tshuaj fluorescent yuav tsum tau tswj xyuas nyob rau hauv ntau yam. Piv txwv li, rau cov hoses xa tawm mus rau Tebchaws Meskas, cov polyethylene (PE) thiab polypropylene (PP) siv yuav tsum ua tau raws li US Food and Drug Administration (FDA) tus qauv 21CFR117.1520.

Barrier zog ntawm cov ntaub ntawv: Yog hais tias cov ntsiab lus ntawm lub ntim ntawm niaj hnub tshuaj tuam txhab uas muag yog ib co khoom uas yog rhiab heev rau oxygen (xws li ib co whitening tshuaj pleev ib ce) los yog cov tshuaj tsw qab yog volatile heev (xws li cov roj yam tseem ceeb los yog ib co roj, acids, ntsev, thiab lwm yam). lwm yam tshuaj corrosive), tsib-txheej co-extruded raj yuav tsum tau siv rau lub sijhawm no. Vim hais tias cov pa permeability ntawm tsib-txheej co-extruded raj (polyethylene / nplaum resin / EVOH / nplaum resin / polyethylene) yog 0.2-1.2 units, thaum cov pa permeability ntawm lub zoo tib yam polyethylene ib leeg-txheej raj yog 150-300 units. Nyob rau hauv ib lub sij hawm ntawm lub sij hawm, qhov poob phaus tus nqi ntawm cov co-extruded raj uas muaj ethanol yog kaum ob lub sij hawm qis dua li ntawm ib txheej txheej. Tsis tas li ntawd, EVOH yog ib qho ethylene-vinyl cawv copolymer nrog zoo heev barrier zog thiab fragrance tuav (lub thickness ntawm 15-20 microns yog qhov zoo tshaj plaws).

Khoom tawv tawv: Cov tuam txhab tshuaj niaj hnub muaj cov kev cai sib txawv rau qhov nruj ntawm cov hoses, yog li yuav ua li cas thiaj li tau txais qhov xav tau nruj? Cov polyethylene feem ntau siv hauv hoses feem ntau yog polyethylene low-density polyethylene, high-density polyethylene, thiab linear low-density polyethylene. Ntawm lawv, qhov tawv ntawm high-density polyethylene yog zoo dua li ntawm tsawg-density polyethylene, yog li qhov xav tau nruj tuaj yeem ua tiav los ntawm kev kho qhov sib piv ntawm high-density polyethylene / low-density polyethylene.

Cov khoom siv tshuaj tiv thaiv: High-density polyethylene muaj tshuaj tiv thaiv zoo dua li cov polyethylene tsawg.

Huab cua tsis kam ntawm cov ntaub ntawv: Txhawm rau tswj lub sijhawm luv lossis lub sijhawm ua haujlwm ntev ntawm lub hose, yam xws li cov tsos, lub siab tsis kam / poob tsis kam, sealing lub zog, ib puag ncig kev ntxhov siab tawg tsis kam (ESCR tus nqi), tshuaj tsw qab thiab tsis muaj cov khoom xyaw xav tau xav txog.

Xaiv cov masterbatch: Masterbatch plays lub luag haujlwm tseem ceeb hauv kev tswj xyuas qhov zoo ntawm cov hose. Yog li ntawd, thaum xaiv masterbatch, tus neeg siv lub tuam txhab yuav tsum xav txog seb nws puas muaj qhov zoo dispersibility, pom thiab thermal stability, huab cua tsis kam thiab cov khoom tsis kam. Ntawm lawv, cov khoom tsis kam ntawm masterbatch yog qhov tseem ceeb tshwj xeeb thaum siv lub hose. Yog hais tias tus masterbatch tsis sib haum nrog cov khoom, cov xim ntawm masterbatch yuav tsiv mus nyob rau hauv cov khoom, thiab qhov tshwm sim yog heev hnyav. Yog li ntawd, cov tuam txhab tshuaj niaj hnub yuav tsum kuaj xyuas qhov ruaj khov ntawm cov khoom tshiab thiab cov hoses (kev ntsuas nrawm raws li cov xwm txheej).

Hom kua roj vanish thiab lawv cov yam ntxwv: Cov kua roj vanish siv nyob rau hauv lub hose yog muab faib ua UV hom thiab cua sov kom qhuav hom, thiab yuav muab faib mus rau hauv ci nto thiab matte nto nyob rau hauv cov nqe lus ntawm cov tsos. Cov kua roj vanish tsis tsuas yog muab cov txiaj ntsig zoo nkauj, tab sis kuj tseem tiv thaiv cov ntsiab lus thiab muaj qee yam cuam tshuam los thaiv cov pa oxygen, dej vapor thiab tshuaj tsw qab. Feem ntau hais lus, cov kua roj vanish ziab tshav kub tau zoo adhesion rau tom qab kub stamping thiab silk-screen luam ntawv, thaum UV kua roj vanish muaj gloss zoo dua. Cov tuam txhab tshuaj niaj hnub tuaj yeem xaiv cov kua roj vanish uas tsim nyog raws li cov yam ntxwv ntawm lawv cov khoom. Tsis tas li ntawd, cov kua roj vanish kho yuav tsum muaj qhov zoo adhesion, qhov chaw du tsis muaj pitting, folding kuj, hnav tsis kam, corrosion kuj, thiab tsis muaj xim thaum khaws cia.

Qhov yuav tsum tau muaj rau lub raj lub cev / raj lub taub hau: 1. Qhov saum npoo ntawm lub raj lub cev yuav tsum du, tsis muaj streaks, khawb, lim, los yog shrinkage deformation. Lub cev lub cev yuav tsum ncaj thiab tsis khoov. Lub raj phab ntsa thickness yuav tsum sib xws. Lub raj phab ntsa thickness, raj ntev, thiab txoj kab uas hla tolerances yuav tsum tsis pub dhau qhov teev;

2. Lub taub hau lub taub hau thiab lub raj lub cev ntawm lub hose yuav tsum ruaj khov, cov kab sib txuas yuav tsum zoo nkauj thiab zoo nkauj, thiab qhov dav yuav tsum tsis sib xws. Lub taub hau raj yuav tsum tsis txhob skewed tom qab kev sib txuas; 3. Lub taub hau lub taub hau thiab lub raj npog yuav tsum sib phim zoo, ntsia hlau rau hauv thiab tawm kom zoo, thiab yuav tsum tsis txhob muaj kev poob qis hauv qhov kev sib tw torque, thiab yuav tsum tsis txhob muaj dej los yog cua nkag ntawm lub raj thiab lub hau;

Cov kev cai luam ntawv: Hose ua feem ntau siv lithographic offset printing (OFFSET), thiab feem ntau ntawm cov number case siv yog UV-dried, uas feem ntau yuav tsum muaj zog adhesion thiab tsis kam mus rau discoloration. Cov xim luam ntawv yuav tsum nyob rau hauv qhov tob qhov ntau, txoj hauj lwm overprint yuav tsum raug, qhov sib txawv yuav tsum nyob rau hauv 0.2 hli, thiab font yuav tsum ua kom tiav thiab meej.

Kev xav tau rau lub kaus mom yas: Lub kaus mom yas feem ntau yog ua los ntawm polypropylene (PP) txhaj tshuaj molding. Cov kaus mom yas zoo yuav tsum tsis muaj qhov pom tseeb shrinkage kab thiab flashing, du pwm kab, yog qhov ntev, thiab du haum nrog lub taub hau raj. Lawv yuav tsum tsis txhob ua rau muaj kev puas tsuaj xws li cov kab nrib pleb lossis kab nrib pleb thaum siv ib txwm siv. Piv txwv li, thaum qhib quab yuam nyob rau hauv qhov ntau, lub flip cap yuav tsum muaj peev xwm tiv taus ntau tshaj 300 folds yam tsis muaj kev tawg.
