✨Comprehensive Analysis of Core Differences and Haum Scenarios for PP/PE Granules
Rau cov neeg nyob hauv kev lag luam yas zaj duab xis, xaiv ntawm PP thiab PE granules yog ib qho teeb meem tsis tu ncua! Ob qho tib si feem ntau siv cov ntaub ntawv raw hauv kev lag luam ua yeeb yaj kiab, tab sis lawv cov kev ua tau zoo thiab cov xwm txheej tsim nyog txawv heev. Niaj hnub no, peb yuav rhuav tshem lawv cov yam ntxwv tseem ceeb, qhov zoo, thiab cov xwm txheej siv tau los pab txawm tias cov pib tshiab xaiv cov khoom raug xaiv.
Cia peb pib nrog PE yas granules. Lawv khav theeb tshwj xeeb toughness thiab muaj zog tsawg-kub tsis kam, tseem muaj zog txawm nyob rau hauv sub- xoom kub. Lawv kuj muaj qhov muag muag, zoo adhesion, thiab zoo heev waterproof thiab ya raws - cov khoom pov thawj. Tsis tas li ntawd, lawv muaj kev ruaj ntseg siab thaum lub sij hawm ua, txo qhov feem ntawm zaj duab xis breakage los yog wrinkling. Feem ntau siv cov yeeb yaj kiab ua los ntawm PE granules suav nrog cov hnab ntim khoom noj (xws li cov hnab ntim khoom noj txom ncauj thiab lub freezer hnab), cov khoom siv niaj hnub ntim cov yeeb yaj kiab, thiab cov yeeb yaj kiab ua liaj ua teb mulch-mulch films xav tau huab cua tsis kam thiab tensile lub zog, thiab PE lub toughness zoo kawg nkaus tiv tshav ntuj stretching thaum tiv thaiv av noo evaporation. Tsis tas li ntawd, lub hnab xa khoom thiab cov hnab yuav khoom feem ntau yog ua los ntawm PE zaj duab xis; lawv muaj peev xwm txaus-cov kabmob muaj peev xwm, tsis yooj yim puas tom qab folding, thiab tsis tuaj yeem tawg txawm tias nqa cov khoom hnyav, ua rau lawv hloov tau yooj yim rau kev siv txhua hnub.
Saib ntawm PP yas granules, lawv qhov zoo muaj xws li hardness siab dua, zoo heev transparency tso cai rau kom pom tseeb ntawm cov khoom nyob rau hauv lub ntim, thiab ho zoo dua kub tsis kam tshaj PE, withstanding kub nyob ib ncig ntawm 100 degree. Lawv kuj muab molding ceev ceev thaum lub sij hawm ua, ua rau ib tug smoother zaj duab xis uas tsis tshua muaj deformation. Cov yeeb yaj kiab PP feem ntau suav nrog cov hnab ntim khoom noj khoom haus (xws li lub hnab ntim khoom noj rau cov khoom noj thiab cov nqaij, cua sov- tiv taus thiab haum rau luv- lub sijhawm cua sov), cov ntawv sau (xws li cov nplooj ntawv nplaub tshev thiab cov hnab ntim cov ntaub ntawv, nruj txaus los tiv thaiv wrinkles), thiab daim ntawv lo zaj duab xis -lawv daim ntawv lo kom pom tseeb thiab daim ntawv thov kom meej meej rau lub raj mis. curling. Tsis tas li ntawd, qee cov yeeb yaj kiab sib xyaw siv hauv ntim kuj tseem siv PP granules, ua ke nrog lwm cov ntaub ntawv los txhim kho tag nrho cov tawv tawv thiab lub teeb xa mus, ntsuas kev tiv thaiv thiab cov teeb pom kev zoo.
Qhov sib txawv tseem ceeb ntawm ob yuav tsum to taub kom meej: PE yog softer thiab hloov tau yooj yim, nrog qis -kub tsis kam, haum rau cov ntawv thov uas xav tau lub zog tensile thiab waterproofing; PP yog tawv, pob tshab, thiab tshav kub-tiv taus, haum rau cov ntawv thov uas xav tau cov zaub thiab siab -kub tsis kam. Rau cov yeeb yaj kiab uas yuav tsum tau rov folding thiab hnyav hnyav, PE yog qhov kev xaiv zoo dua; rau cov lus qhia pob tshab thiab luv luv -lub sij hawm tshav kub tsis kam, PP yog qhov tsim nyog dua. Tsis tas li ntawd, thaum ua tiav, nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias PE muaj qhov ua haujlwm qis me ntsis, kev ruaj ntseg dua, thiab siab dua rau kev ua yuam kev los ntawm cov neeg pib tshiab; PP kev ua haujlwm yuav tsum tau ua tib zoo tswj qhov kub thiab txias kom tsis txhob yellowing thiab txo cov pob tshab vim qhov kub thiab txias.
Txawm hais tias rau ntim khoom noj, ntim khoom noj txhua hnub, lossis kev ua liaj ua teb thiab kev ua yeeb yaj kiab, xaiv cov PP / PE granules yog qhov tseem ceeb los xyuas kom meej cov yeeb yaj kiab zoo thiab tsis txhob muaj teeb meem xws li zaj duab xis tawg, tsis zoo lub teeb kis tau tus mob, thiab tsis muaj zog. Rau cov neeg uas xav tau kev ua yeeb yaj kiab tshwj xeeb, peb tuaj yeem phim cov ntaub ntawv raw raws li qhov xwm txheej, pab cov neeg pib tshiab kom tsis txhob muaj kev xaiv cov khoom siv pitfalls.
