Lub peev xwm lub nra hnyav me me feem ntau nyob ntawm ob peb cov khoom tseem ceeb: cov khoom siv tuab, loj, thiab cov qauv tuab, thiab qauv tuab, thiab qauv tuab, thiab cov qauv tuab, thiab cov qauv tuab, thiab cov qauv tuab, thiab cov qauv tuab, thiab cov qauv ntsuas. Ntawm no yog kev tsom xam:
1. Cov khoom txiav txim siab thauj khoom muaj peev xwm
Cov ntaub ntawv cov khoom siv yog LDPE lossis LLDPE, uas muaj zoo hloov thiab tensile muaj zog.
LDPE feem ntau muaj qhov nruab nrab load muaj peev xwm, haum rau lub teeb yuag.
Lldpe yog cov kua muag dua ntxiv - tiv taus thiab muaj peev xwm zoo dua.
Lub hnab ntim me me ldpe rov qab los yog feem ntau siv rau cov khoom yuag.
2. Thickness (microns lossis mob me) yog qhov tseem ceeb tshaj plaws
Qhov ntau dua qhov tuab, lub zog ua kom muaj peev xwm thauj khoom muaj peev xwm.
Kev xa khoom muaj peev xwm (kev paub txog kev lag luam dav dav):
Hnab tuab - ntau qhov ntau thiab tsawg - pom zoo ruaj ruaj
0.04-0.05 hli (kwv yees {{}}} × 6cm-8 × 12G {9} g-80g
0.06-0.08mm (kwv yees . 2.4}}}} - 3 lab lub hnab me me {5} g-150g
0.1 hli (kwv yees {{1} mil) thiab saum toj {}}}} {}} g-300g
Yog hais tias lub hnab yog qhov me me heev (piv txwv li, 4 × 6cm), lub peev xwm thauj khoom tuaj yeem siab dua; Yog tias lub hnab loj dua, lub nra yuav tsawg dua.
3. Lub kaw lus kaw kuj cuam tshuam rau thauj khoom - bearing muaj peev xwm.
Sing {{0- pob txha kaw: Haum rau cov khoom me me xws li cov noob hlaws ua ke, khawm, thiab qhov chaw.
Ob npaug - pob txha kaw: nce load {{1} {cov kabmob muaj peev xwm los ntawm 20% -30%.
Twiple - pob txha kaw: siv rau cov khoom lag luam siab dua {{} {{2} {{2} Daim ntawv thov pov thawj pov thawj.
4. Thauj {{- Cov kabmob muaj peev xwm siv hauv cov ntawv thov kev siv.
Me ntsis pob tshab self - Sealing hnab muaj feem ntau siv rau:
Cov hniav nyiaj hniav kub accessories, qhwv ntsej, ib ncig (ob peb gram)
Screws, Cov Khoom Kho Me Me (20G-80G)
Reassent hmoov, granules (30g-100g)
Cheebtsam hluav taws xob me me (kaum ntawm grams)
Nws yog feem ntau tsis pom zoo kom ntim cov khoom hnyav lossis cov khoom ntse kom tsis txhob tawg lossis hno.
Lub hnab ntim khoom me me uas muaj cov ntaub ntawv ntshiab yooj yim muaj lub nra hnyav - cov kabmob muaj sia ntawm 20g thiab 150g.
Qhov ntau dua cov tuab, qhov muaj zog dua kaw, thiab lub hnab me me, qhov zoo dua lub nra {{bearing {cov kabmob muaj peev xwm.
