1. Lub compression ratio ntawm ib tug ntsia hlau extruder ntsia hlau yog haum ntawm 1: 2-1: 3, nyiam dua 1: 2.5, thiab qhov zoo tshaj plaws ntev rau txoj kab uas hla ntawm peb-theem ntsia hlau yog 25. Ib tug zoo ntsia hlau tsim yuav zam cov khoom. decomposition thiab cracking tshwm sim los ntawm kev sib txhuam hnyav.Piv txwv tias cov ntsia hlau ntev yog L, ntu pub yog 0.3L, ntu compression yog 0.4L, qhov ntsuas qhov ntsuas yog 0.3L, thiab qhov sib txawv ntawm lub hau ntsia hlau thiab cov ntsia hlau yog 0.1-0.2 hli.Lub phaj honeycomb ntawm lub taub hau ntawm lub tshuab yuav tsum muaj 1.5-5 hli qhov, siv ob lub 400 qhov / cmsq lim (kwv yees li 50 mesh).Thaum extruding pob tshab lub xub pwg pluaj, lub cev muaj zog horsepower feem ntau yuav tsum tau tiv thaiv lub cev los ntawm stalling lossis hlawv tawm vim overload.Feem ntau, PVC lossis BM screws muaj, tab sis luv compression seem screws tsis haum.
2. Lub molding kub nyob ntawm cov ntaub ntawv ntawm cov tuam txhab sib txawv, thiab qhov siab dua qhov hardness, siab dua qhov kub extrusion.Kev ua haujlwm kub nce los ntawm 10-20 ℃ los ntawm ntu pub mis mus rau qhov ntsuas ntsuas.
3. Yog hais tias tus ntsia hlau ceev ceev heev thiab kev sib txhuam yog overheated vim shear kev nyuaj siab, qhov chaw ceev yuav tsum tau tswj ntawm 12-60rpm, thiab tus nqi tshwj xeeb yog nyob ntawm cov ntsia hlau txoj kab uas hla.Qhov loj ntawm txoj kab uas hla, qhov qeeb qeeb.Txhua yam khoom sib txawv thiab kev saib xyuas yuav tsum tau them rau cov kev xav tau ntawm tus neeg muag khoom.
4. Ua ntej siv, cov ntsia hlau yuav tsum tau ntxuav kom huv si, thiab PP lossis HDPE tuaj yeem siv los ntxuav ntawm qhov kub siab dua.Cov tshuaj ntxuav kuj tseem siv tau los ntxuav.
5. Tus tsim ntawm lub taub hau tshuab yuav tsum tau streamlined thiab yuav tsum tsis muaj cov ces kaum tuag kom ntseeg tau tias cov ntaub ntawv du.Cov kabmob ntawm lub tes tsho pwm tuaj yeem txuas ntxiv kom tsim nyog, thiab lub kaum sab xis ntawm lub tes tsho pwm yog tsim los ntawm 8-12 °, uas yog tsim nyog los txo qis kev ntxhov siab, tiv thaiv qhov muag poob thaum lub sij hawm tsim khoom, thiab ruaj khov rau extrusion. tus nqi.
6. TPU muaj cov coefficient siab ntawm kev sib txhuam thiab tsis yooj yim rau cov duab.Qhov ntev ntawm lub tank dej txias yuav tsum ntev dua li lwm cov ntaub ntawv thermoplastic, thiab TPU nrog lub siab tawv yog yooj yim dua rau kev tsim.
7. Cov tub ntxhais hlau yuav tsum qhuav thiab tsis muaj roj stains kom tsis txhob muaj npuas tshwm sim vim cua sov.Thiab xyuas kom meej qhov zoo tshaj plaws ua ke.
8. TPU belongs rau qeb ntawm cov ntaub ntawv yooj yim hygroscopic, uas sai sai nqus dej noo thaum muab tso rau hauv cov huab cua, tshwj xeeb tshaj yog thaum cov ntaub ntawv ether yog hygroscopic ntau dua li cov ntaub ntawv polyester.Yog li ntawd, nws yog ib qho tsim nyog los xyuas kom meej qhov kev sib khi zoo.Cov ntaub ntawv muaj ntau dua rau kev nqus dej noo nyob rau hauv cov xwm txheej kub, yog li cov khoom seem yuav tsum tau muab kaw sai sai tom qab ntim.Tswj cov dej noo hauv qab 0.02% thaum ua haujlwm.
