Yuav ua li cas xaiv cov raj yas zoo

Cov raj yas, ib yam khoom siv ntim khoom yooj yim thiab pheej yig, tau siv dav hauv kev lag luam tshuaj lom neeg txhua hnub thiab nrov heev. Cov raj yas zoo tsis tsuas yog tiv thaiv cov ntsiab lus xwb tab sis kuj txhim kho qib khoom, yog li pab cov tuam txhab tshuaj lom neeg txhua hnub yeej cov neeg siv khoom ntau dua. Yog li, rau cov tuam txhab tshuaj lom neeg txhua hnub, yuav ua li cas xaiv cov raj yas zoo uas haum rau lawv cov khoom? Hauv qab no, peb yuav qhia los ntawm ntau yam tseem ceeb.

Qhov tawv ntawm cov khoom siv: Cov kev cai rau qhov tawv ntawm cov raj sib txawv ntawm cov tuam txhab tshuaj lom neeg txhua hnub. Yog li, yuav ua li cas thiaj ua tiav qhov tawv xav tau? Cov polyethylene feem ntau siv hauv cov raj feem ntau suav nrog cov polyethylene qis-density, polyethylene siab-density thiab polyethylene qis-density.

Kev tiv thaiv tshuaj lom neeg ntawm cov ntaub ntawv: Cov polyethylene siab ntom ntom muaj kev tiv thaiv tshuaj zoo dua li cov polyethylene qis ntom ntom.

Kev tiv thaiv huab cua ntawm cov ntaub ntawv: Txhawm rau tswj kev ua haujlwm luv luv lossis ntev ntawm cov raj, cov yam xws li qhov tsos, kev tiv thaiv siab / poob, lub zog sealing, kev tiv thaiv kev tawg ntawm ib puag ncig (ESCR tus nqi), tsw qab thiab kev poob ntawm cov khoom xyaw nquag yuav tsum tau xav txog.

Kev xaiv cov xim masterbatches: Cov xim masterbatches ua lub luag haujlwm tseem ceeb hauv kev tswj xyuas zoo ntawm cov raj. Yog li ntawd, thaum xaiv cov xim masterbatches, cov neeg siv cov lag luam yuav tsum xav txog seb lawv puas muaj kev sib kis zoo, kev lim dej thiab kev ruaj khov thermal, kev tiv thaiv huab cua thiab kev tiv thaiv khoom. Cov tuam txhab tshuaj lom neeg txhua hnub yuav tsum sim qhov ruaj khov ntawm cov khoom tshiab thiab cov raj (ua qhov kev sim ceev hauv qab cov xwm txheej tshwj xeeb).

Cov hom varnish thiab lawv cov yam ntxwv: Cov varnish siv rau cov raj yog muab faib ua hom ultraviolet (UV) thiab hom cua sov ziab. Hais txog qhov tsos, nws tuaj yeem muab faib ua glossy thiab matte. Varnish tsis yog tsuas yog muab cov nyhuv pom zoo nkauj xwb, tab sis kuj tiv thaiv cov ntsiab lus thiab muaj qee yam cuam tshuam rau oxygen, dej pa thiab tsw qab.

Cov Kev Cai rau lub cev yeeb nkab/lub taub hau yeeb nkab: 1. Qhov chaw ntawm lub cev yeeb nkab yuav tsum du thiab huv si, tsis muaj kab txaij, khawb, khawb, thiab kev hloov pauv ntawm lub cev yeeb nkab. Lub cev yeeb nkab yuav tsum ncaj thiab tsis khoov. Qhov tuab ntawm phab ntsa yeeb nkab yuav tsum sib npaug. Qhov ntev ntawm phab ntsa yeeb nkab, qhov ntev ntawm yeeb nkab, thiab txoj kab uas hla yuav tsum nyob hauv qhov ntau thiab tsawg teev tseg.

Cov Kev Cai Luam Ntawv: Kev luam ntawv OFFSET feem ntau yog siv rau kev ua cov kav dej, thiab feem ntau ntawm cov kua mem siv yog UV-qhuav. Nws feem ntau xav tau kev nplaum zoo thiab xim tsis kam ntawm cov kua mem. Cov xim luam ntawv yuav tsum nyob hauv qhov tob uas tau teev tseg, qhov chaw luam ntawv yuav tsum raug, qhov sib txawv yuav tsum nyob hauv 0.2 hli, thiab cov ntawv yuav tsum tiav thiab meej.

Cov Kev Cai rau Cov Hau Yas: Cov hau yas feem ntau yog txhaj tshuaj pwm los ntawm polypropylene (PP). Cov hau yas zoo yuav tsum tsis muaj cov cim shrinkage lossis flashing, kab kaw pwm yuav tsum du, qhov loj me yog qhov tseeb, thiab lawv yuav tsum haum zoo nrog lub taub hau yeeb nkab. Thaum siv li niaj zaus, lawv yuav tsum tsis ua rau puas tsuaj rau cov qauv xws li brittleness lossis tawg. Piv txwv li, thaum lub zog qhib nyob hauv qhov ntau thiab tsawg, lub hau tig yuav tsum tuaj yeem tais tau ntau dua 300 zaug yam tsis muaj kev tawg.

Nws ntseeg tau tias los ntawm kev pib los ntawm cov yam saum toj no, feem ntau ntawm cov lag luam tshuaj lom neeg txhua hnub yuav tsum muaj peev xwm xaiv cov khoom ntim khoom zoo.
