3, Kev ua cov ntaub ntawv
- Haum rau dav extruder, nws kuj tuaj yeem raug extruded los ntawm cov ntsia hlau dav dav rau PVC. Txhawm rau txhawb kev tsim khoom, cov ntsia hlau qis compression (L / D Ntau dua lossis sib npaug rau 20 piv, compression piv 1.2: 1) tau qhia.
- Txij li thaum qhov kub ntawm qhov sib xyaw melting muaj feem xyuam rau qhov sib piv, qhov sib piv thiab cov qauv ntawm cov ntsia hlau, qhov kub ntawm extruding yuav tsum raug txhais raws li qhov tseeb ntawm extruder, tab sis qhov kub ntawm melting compound yuav tsum tsis pub tshaj 170 degree. .
- Extruder nruab nrog tshwj xeeb ntsia hlau rau LSZH compound yog pom zoo, qhov kub thiab txias:
Cheeb tsam 1 tsam 2 tsam 3 tsam 4 crosshead tuag
Kub (degree) 120 130 140 150 155 155
4, Pob
(25 ±{1}}.2) kg/bag, puab pob nrog Aluminium Foil hnab, txheej pob nrog kraft-yas hnab ntawv.
5, Kev thauj mus los thiab kev cia khoom
Lub compound yuav tsum tau tiv thaiv los ntawm tshav ntuj thiab los nag thaum lub sij hawm thauj mus los, thiab muab cia rau hauv huv si, txias, qhuav thiab ventilated qhov chaw. Yog tias nws siv tom qab ntau tshaj 2-hli cia , thov kom qhuav cov khoom hauv qab 60-70 degree nrog qhov cua kom tsawg kawg 2 teev ua ntej siv. Hnub tas sij hawm yog 6 lub hlis txij li hnub tsim khoom.
