Cov khoom siv niaj hnub tsis yog tshiab rau peb. Peb yuav tsum tiv tauj nrog txhua yam khoom siv niaj hnub txij li thaum peb ntxuav thaum sawv ntxov. Niaj hnub no peb yuav tham txog cov npe ntawm cov khoom siv niaj hnub.
Nyob rau hauv xyoo tas los no, nrog rau kev loj hlob ntawm tib neeg thiab kev lag luam, daim ntawv lo luam ntawv tau hloov nrog txhua hnub dhau mus, thiab tau nthuav dav hauv txhua yam ntawm tib neeg txoj haujlwm thiab lub neej. Yuav luag txhua yam khoom siv niaj hnub hauv lub neej siv qee cov ntawv nplaum rau tus kheej cov khoom lag luam. Raws li cov khoom sib txawv, kev lag luam khoom siv niaj hnub tuaj yeem muab faib ua cov khoom siv tu tus kheej (xws li cov tshuaj zawv plaub hau thiab cov khoom tu plaub hau, cov khoom siv da dej, cov khoom tu tawv nqaij, xim pleev xim, naj hoom, thiab lwm yam) thiab cov khoom tu tsev (xws li khaub ncaws thiab cov khoom siv tu, khoom siv tu chav ua noj, khoom siv hauv chav dej, thiab lwm yam) los ntawm kev lag luam ntu.
Cov yam ntxwv ntawm cov khoom siv txhua hnub
1 、 Muaj ntau hom kev luam ntawv thiab cov txheej txheem luam ntawv
Tam sim no, muaj ntau yam khoom siv tshuaj niaj hnub nrog ntau yam kev siv thiab kev ua yeeb yam, suav nrog cov ntawv sau rau ntawm daim ntawv lossis cov ntawv sib xyaw, cov ntawv sau rau ntawm Petrochemical polymers, thiab cov ntawv sau rau ntawm iav thiab hlau. Cov ntawv sau tuaj yeem luam tawm nyias thiab muab tso rau hauv cov khoom, xws li cov ntawv nplaum rau tus kheej; Nws tseem tuaj yeem luam tawm ncaj qha rau ntawm qhov chaw ntawm cov khoom, xws li cov ntawv luam ntawv hlau. Kev sib txawv ntawm cov ntaub ntawv luam tawm yuav ua rau muaj kev sib txawv ntawm kev luam ntawv.
Kev tsim kho kev lag luam ntawm ntsuab ib puag ncig tiv thaiv ntim thiab ntim khoom zoo tau muab tso rau hauv kev xav tau ntau dua rau kev luam ntawv zoo ntawm cov ntawv tshuaj txhua hnub. Nws tsis tsuas yog xav kom cov ntawv sau tshuaj niaj hnub muaj qhov zoo nkauj zoo nkauj, tsis tshua muaj nqi luam ntawv thiab siv tau yooj yim, tab sis kuj xav kom lawv yooj yim rau rov siv dua thiab rov siv dua thiab tiv thaiv cov khoom cuav. Yog li txhawm rau txhawm rau ua kom cov xim thiab cov ntsiab lus ntawm cov ntawv sau tshuaj txhua hnub kom ua tiav ntau qhov tseeb thiab zoo nkauj, thiab siv ntau txoj kev luam ntawv thiab xa xov xwm txheej txheem, thiab txais yuav cov ntaub ntawv luam tawm ib puag ncig.
2 、 Kev sib koom ua ke ntawm cov khoom piav qhia thiab cov khoom tso tawm
Nrog rau kev txhim kho kev lag luam thiab kev lag luam thoob ntiaj teb, cov khoom siv niaj hnub, tshwj xeeb tshaj yog cov tshuaj pleev ib ce, tau dhau los ua cov khoom tseem ceeb hauv ntau lub khw muag khoom lag luam thiab khw muag khoom. Kev sib tw hauv kev lag luam khoom siv niaj hnub tau maj mam sib xyaw ua ke ntawm cov khoom ntim khoom ntim thiab cov khoom lag luam sib cais, thiab tseem txhawb nqa cov ntawv tseem ceeb txhua hnub kom sib koom ua ke ob lub luag haujlwm tseem ceeb ntawm cov khoom piav qhia thiab cov khoom lag luam los ntawm kev siv kev sib xyaw ntawm ntau txoj kev luam ntawv thiab kev sib xyaw ua ke ntawm Ntau cov ntaub ntawv luam tawm, Nws ua rau cov ntawv cim ntawm cov khoom tsim nyog txhua hnub los ua cov khoom tsim, luam ntawv thiab ua tiav raws li qhov xav tau ntawm "cov khoom zoo nkauj, kev txheeb xyuas tseeb, kev ua haujlwm ruaj khov thiab cov txheej txheem tshwj xeeb", thiaj li ua kom ntseeg tau tias cov ntawv cim ntawm cov khoom siv niaj hnub xav tau. yog "zoo nkauj hauv tsos, muag heev hauv kev ntxhib los mos, ruaj thiab txhim khu kev qha".
3 、 Nws muaj kev ruaj ntseg zoo thiab tshuaj lom neeg ruaj khov
Cov khoom siv niaj hnub muaj qhov tshwj xeeb muag thiab siv ib puag ncig, uas tsis yog tsuas yog yuav tsum muaj cov ntawv sau tshuaj txhua hnub kom muaj lub luag haujlwm tshwj xeeb kom ua tau raws li qhov ntim cov nyhuv, tab sis kuj yuav tsum muaj lub cev ruaj khov thiab cov yam ntxwv tshuaj xws li dej tsis kam, noo noo tsis kam, extrusion resistance, abrasion resistance, tsim kua muag. kuj thiab corrosion kuj. Piv txwv li, cov tshuaj ntxuav lub ntsej muag thiab cov tshuaj nplaum uas nquag siv yuav tsum tiv taus extrusion, puas thiab tsim kua muag. Yog tias cov khoom siv tshuaj niaj hnub tsis tau siv tas li, thiab cov ntawv sau saum npoo tau raug puas los yog tshem tawm, cov neeg siv khoom yuav muaj kev tsis ntseeg txog qhov zoo ntawm cov khoom. Cov tshuaj zawv plaub hau thiab da dej gel siv hauv chav dej, chav dej thiab lwm qhov chaw xav kom lawv cov ntawv tshuaj txhua hnub muaj dej-resistant, noo noo-pov thawj thiab corrosion-resistant zog. Txwv tsis pub, cov ntawv yuav poob thiab siv tsis raug, ua rau muaj kev phom sij. Yog li ntawd, kev ntsuam xyuas lub cev thiab tshuaj tom qab luam tawm cov ntawv sau tshuaj txhua hnub yog qhov txawv ntawm lwm cov khoom luam tawm.
Cov ntaub ntawv siv rau cov ntawv sau tshuaj txhua hnub
Cov ntaub ntawv hauv paus ntawm daim ntawv nplaum tus kheej yog cov ntawv coated, thiab qhov ci ntsa iab thiab dej tsis zoo yog txhim kho los ntawm cov yeeb yaj kiab txheej. Txoj kev luam ntawv feem ntau yog offset luam ntawv rau cov khoom siv high-end, thiab flexographic luam ntawv thiab tshuaj ntsuam luam ntawv rau cov khoom nruab nrab thiab qis kawg. Cov ntaub ntawv tseem ceeb ntawm cov ntawv nplaum yog PE (polyethylene zaj duab xis), PP (polypropylene zaj duab xis) thiab ntau yam sib xyaw ntawm PP thiab PE. Ntawm lawv, cov khoom siv PE yog qhov muag muag, nrog kev ua haujlwm zoo thiab kev ua haujlwm zoo. Nws yog feem ntau siv rau lub raj mis uas yuav tsum tau extruded ntau zaus thiab yooj yim deformed. PP cov khoom muaj siab hardness thiab tensile kuj, uas yog haum rau luam ntawv tuag txiav thiab tsis siv neeg labeling. Nws yog feem ntau siv rau "pob tshab daim ntawv lo" ntawm lub cev pob tshab lub raj mis. Polyolefin zaj duab xis tov nrog PP thiab PE tsis yog tsuas yog mos thiab extrusion resistant, tab sis kuj muaj siab tensile kuj. Nws muaj cov cuab yeej zoo hauv qab no, luam ntawv tuag txiav thiab tsis siv neeg daim ntawv lo. Nws yog ib qho zoo tagnrho cov ntaub ntawv daim ntawv lo.
