Perforated steel strip polyethylene composite yeeb nkab yog ua los ntawm txias-dov strip steel thiab thermoplastics raws li raw cov ntaub ntawv, thiab ntxeem tau nyias-walled steel kav tsim los ntawm argon arc taub qab vuam los yog plasma kauv vuam yog siv los ua reinforcements. Cov txheej txheej sab nrauv thiab sab hauv yog ob sab sib xyaw thermoplastics. Ib hom tshiab ntawm cov yeeb nkab siab, Vim tias qhov ntxeem tau nyias-walled steel yeeb nkab reinforcement yog qhwv hauv cov thermoplastic tsis tu ncua, cov yeeb nkab sib xyaw no tsis tsuas yog kov yeej cov kev ua tsis zoo ntawm cov kav hlau thiab cov kav dej yas, tab sis kuj muaj cov rigidity ntawm cov kav hlau thiab cov corrosion. tsis kam ntawm cov kav dej yas. Nws yog kev daws teeb meem rau roj av thiab tshuaj lom neeg kev lag luam. Nws yog ib qho kev xav tau ceev ceev ntawm cov kav dej loj thiab nruab nrab txoj kab uas hla hauv cov chaw muag tshuaj, khoom noj, mining, roj thiab lwm yam kev lag luam. Nws kuj yog ib qho kev hloov kho thev naus laus zis los daws cov kav dej loj ntawm kev tsim kho thiab hauv nroog dej. Nws yog ib hom tshiab ntawm cov kav dej sib txuas hauv 21stxyoo pua.
Hygienic kev ua tau zoo
Kev nyab xeeb kev nyab xeeb thiab kev nyab xeeb ntawm perforated steel strip yas composite yeeb nkab ua tau raws li qhov yuav tsum tau ua ntawm GB9687 "Hygienic Standard for Polyethylene Moulded Products for Food Packaging" thiab GВ/Т17219 "Safety Evaluation Standard for Drinking Water Distribution Equipment and on Equipment and Protective". Nws yog qhov zoo tshaj plaws hloov rau galvanized yeeb nkab thiab cam khwb cia hlau yeeb nkab.
Smooth sab hauv phab ntsa thiab ncig kev ua haujlwm
Sab hauv phab ntsa ntawm lub mesh steel siv cov yeeb nkab sib txuas yog du heev, thiab qhov roughness tsuas yog 1/20 ntawm cov yeeb nkab steel. Lub peev xwm conveying nyob rau hauv tib lub sijhawm yog li 30% siab dua li ntawm cov yeeb nkab steel.

Lus Cim: Lub nominal siab ntawm cov yeeb nkab sib xyaw yog qhov siab tshaj plaws tso cai rau cov yeeb nkab thauj dej ntawm 20 ° C. Yog tias qhov kub thiab txias hloov, lub siab ua haujlwm yuav tsum raug kho raws li qhov kub siab coefficient ntawm cov khoom sib txawv. S tus nqi: qhov kev ncua deb ntawm sab nraud ntawm qhov kev txhawb nqa mus rau sab nrauv ntawm cov yeeb nkab. |
