Cov yam ntxwv tseem ceeb ntawmNanhai YajYas Extruder Tshuab yog "nruam conveying, high-efficiency plasticizing, thiab ruaj khov molding."
Lub extruder muaj tsib lub hauv paus ntsiab lus los ntawm kev pub mis mus rau molding, txhua tus muaj lub luag haujlwm kom meej meej thiab ua haujlwm sib koom tes:
1. Pub System
Cov khoom tseem ceeb: hopper, feeder (sib faib rau hauv lub ntiajteb txawj nqus noj thiab yuam pub mis).
Muaj nuj nqi: Stably conveys khoom yas granules / hmoov rau cov ntsia hlau feed seem, tsis txhob "bridging" (khoom siv blockage nyob rau hauv lub hopper). Forced feeders (xws li ntxaib-ntsia hlau feeders) yog tsim rau high-viscosity los yog yooj yim agglomerated cov ntaub ntawv, nrog ib tug pub mis raug ntawm ± 1%.
2. Plasticizing System
Cov khoom tseem ceeb: ntsia hlau, chim, cua sov thiab cua txias.
Muaj nuj nqi: Qhov chaw tseem ceeb rau "kua-kua hloov pauv" ntawm cov yas. Cov kev sib hloov ntawm cov ntsia hlau tsim lub zog shear, uas, ua ke nrog cov cua sov ntawm lub thoob (feem ntau yog 3-5 ntu), maj mam softens thiab melts cov khoom yas; cov cuab yeej ua kom txias (xws li dej txias lossis cua txias) tswj lub chim kub kom tsis txhob overheating thiab degradation ntawm cov khoom.
Cov ntsiab lus tseem ceeb: Cov ntsia hlau ntev-rau-inch piv (L / D) feem ntau yog 20: 1-30: 1. Cov cua kub kub yog hloov kho raws li cov khoom siv yas (piv txwv li, PE 180-220 ℃, PVC 160-190 ℃).
3. Kev sib kis
Core Cheebtsam: lub cev muaj zog, gearbox, coupling.
Muaj nuj nqi: Muab lub zog ruaj khov rau cov ntsia hlau thiab tswj cov ntsia hlau ceev (feem ntau 10-100 r / min). Lub cev muaj zog feem ntau siv lub cev muaj zog ntau zaus lossis servo lub cev muaj zog, tso cai rau kev hloov ceev ceev; lub gearbox txo lub cev muaj zog ceev thiab nce torque kom ua tau raws li qhov xav tau ntawm kev ua haujlwm siab ntawm cov ntsia hlau.
4. Tuag Lub Taub Hau thiab Pwm System
Cov khoom tseem ceeb: Lub taub hau tuag (txuas rau lub thoob thiab pwm), pwm (txiav txim siab cov khoom seem ntawm cov khoom).
Muaj nuj nqi: Qhia molten yas rau hauv pwm kab noj hniav thiab extrudes nws mus rau hauv cov duab tshwj xeeb (xws li, kav, nplooj ntawv, profiles). Cov pwm yuav tsum tau ua kom zoo raws li cov khoom loj. Cov hom muaj xws li cov yeeb nkab pwm, pwm lub qhov ncauj tiaj tus (cov ntawv / cov yeeb yaj kiab), thiab cov pwm tsis zoo (qhov rooj thiab qhov rai profiles).
5. Kev ua kom txias, txias, thiab traction system
Cov ntsiab lus tseem ceeb: Shaping lub tes tsho (piv txwv li, lub tes tsho nqus sizing, calendering roller), lub tank txias (dej-txias / cua-txias), traction tshuab.
Kev Ua Haujlwm: Ua kom txias sai sai thiab ua kom cov txheej txheem extruded high-temperature profile, thaum ib txhij tractioning nws ntawm ib tug uniform ceev los ntawm lub tshuab traction los xyuas kom meej qhov seem stability ntawm cov khoom (xws li, yeeb nkab phab ntsa thickness sib txawv ≤ ± 0.1mm). Lub traction ceev yuav tsum phim lub extrusion ceev kom tiv thaiv cov khoom stretching los yog wrinkling.
Nyob ntawm cov kev xav tau ntau lawm, peb tuaj yeem muab tauib leeg-ntsia hlau extruders, ntxaib-ntsia hlau extruders, thiab extrusion ntau lawm kab.
