PE ua npuas ncauj net tshuab yog ib yam khoom tshwj xeeb tsim los tsim cov mos mos, cushioning net tes tsho feem ntau siv los tiv thaiv cov khoom tsis yooj yim xws li txiv hmab txiv ntoo, iav, thiab khoom siv hluav taws xob thaum thauj. Qhov zoo thiab cov khoom ntawm qhov kawg ua npuas ncauj yog qhov tsim nyog txiav txim siab los ntawm cov khoom siv raw khoom noj rau hauv PE foam net tshuab. Kab lus no qhia txog cov ntaub ntawv tseem ceeb thiab cov khoom pabcuam uas xav tau rau kev ua haujlwm thiab piav qhia lawv cov haujlwm tshwj xeeb hauv cov txheej txheem foaming.
Thawj Raw Khoom: Lub Foundation ntawm Foam Net
Cov khoom tseem ceeb siv hauv PE ua npuas ncauj tshuab yog Tsawg-Density Polyethylene (LDPE) resin. Cov khoom siv yas no ua lub hauv paus polymer los tsim cov qauv ua npuas ncauj. Lub tshuab ua cov txheej txheem LDPE, uas paub txog nws qhov yooj yim thiab muaj peev xwm nthuav dav. Feem ntau, cov resin yog nyob rau hauv daim ntawv ntawm pellets uas tau pub rau hauv lub tshuab hopper
Hauv qee cov qauv, ib feem ntawm Linear Low-Density Polyethylene (LLDPE) tuaj yeem muab sib xyaw nrog LDPE hauv qhov sib piv ntawm 3: 1 los hloov cov khoom ntawm lub vas kawg, txhim kho nws lub zog thiab kav ntev.
Kev xaiv cov qib LDPE tshwj xeeb, xws li cov tuam txhab loj petrochemical, yog ib kauj ruam tseem ceeb hauv kev ua kom muaj kev sib raug zoo thiab siab - cov khoom tsim tawm los ntawm PE ua npuas ncauj tshuab
Foaming Agent thiab Key Additives
Tshaj li cov yas resin, kev ua haujlwm ntawm PE ua npuas ncauj tshuab tso siab rau ntau qhov tseem ceeb ntxiv uas ua rau thiab tswj cov txheej txheem foaming.
Foaming Agent: Cov yam ntxwv ua npuas ncauj yog tsim los ntawm kev siv lub cev foaming tus neeg saib xyuas, feem ntau yog butane gas 1810. Lub PE ua npuas ncauj tshuab txhaj tshuaj butane rau hauv LDPE yaj hauv lub extruder. Raws li kev sib xyaw ua ke raug yuam los ntawm lub taub hau tuag, qhov txo qis ua rau cov butane nthuav dav, tsim suav tsis txheeb, kaw - xov tooj cua npuas thoob plaws hauv cov yas 110. Qhov ntau ntawm butane siv yog qhov tseem ceeb; ntau dhau tuaj yeem ua rau lub ntsej muag ntxhib, thaum me me dhau yuav ua rau tsis txaus foaming thiab nce lub tshuab siab 10. Natural gas kuj tau hais tias yog lwm yam tshuab tshuab hauv qee lub tshuab 67.
Nucleating Agent: Ultra- zoo talc hmoov yog ib qho tseem ceeb additive uas ua raws li ib tug nucleating tus neeg sawv cev 110. Ntxiv nyob rau hauv proportions ntawm kwv yees li 2-5 kilograms ib tuj ntawm LDPE, cov talc hais muab qhov chaw rau npuas tsim, ua rau ib tug uniform cell qauv thiab ib tug zoo nto tag rau ntawm lub npuas net 10 ntawm 2, feem ntau 2. yog ib qho tseem ceeb rau nws cov hauj lwm zoo 10.
Cov Txheej Txheem Pabcuam thiab Stabilizer: Glyceryl Monostearate (GMS), tseem hu ua "ib glyceride" lossis los ntawm lub npe lag luam "Plastic Treasure," yog lwm qhov tseem ceeb ntxiv 110. Siv ntau dua (ze li 20-50 kg ib tuj ntawm LDPE), nws ua ntau yam kev ua haujlwm zoo li 1. lub tshuab ntsia hlau, thiab lub stabilizer uas pab tswj ua npuas ncauj cov qauv ntawm tes, tiv thaiv shrinkage tom qab extrusion thiab ua kom cov khoom zoo sib xws 110.
Hauv cov ntsiab lus, kev ua haujlwm zoo ntawm PE ua npuas ncauj tshuab yog nyob ntawm daim ntawv qhia meej ntawm cov ntaub ntawv raw. LDPE resin tsim cov pob txha, thaum cov roj butane hloov nws mus ua npuas dej. Cov khoom ntxiv xws li talc hmoov thiab glyceryl monostearate yog qhov tseem ceeb rau kev tswj cov npuas dej zoo, ruaj khov, thiab zoo li. Kev nkag siab txog cov ntaub ntawv no yog qhov tseem ceeb rau kev ua kom zoo tshaj plaws nrog PE ua npuas ncauj tshuab.
