Peb kuj tau qhia txog cov txheej txheem ntau lawm ntawm PVC ua npuas board ua ntej, vim tias tam sim no ntau thiab ntau daim ntawv thov rau cov khoom no, peb kuj nce nws cov ntau lawm, yog li qhov no xav kom peb ua ntau dua cov khoom lag luam zoo uas nws qhov zoo kuj tuaj yeem siv zoo dua, yog li ua ntej ntawm txhua yam peb yuav tsum npaj hauv kev tsim khoom,
1. Huv si thiab theem lub taub hau pwm thiab nruab rau nws. Qhov qhib ntawm qhov tuag yog feem ntau kho tau li ntawm 0.5-2.0 hli (nyob ntawm qhov tuab), qhov qhib nruab nrab yog me me dua, thiab qhov xaus me ntsis loj dua;
2, tshawb xyuas seb puas yog txoj kab dej, hluav taws xob Circuit Court, pa taws, thiab lwm yam yog qhov qub, thiab kho kom zoo;
3. Qhib lub zog ntawm tus tswv tsev thiab muab qhov kub thiab txias ntawm txhua ntu:
(1) Kev siv teeb tsa qhov tsis xws luag: Thawj thaj tsam plaub rau ntawm PVC ua npuas ncauj npov yog: 170 ° C, 165 ° C, 160 ° C, 150 ° C;
2 (2) Cov ntsiab lus hloov ua haujlwm: 140 ° C-145 ° C Ntsia kub: 70-95 ° C Qhov kub nruab nrab ntawm lub tshuab taub hau yog tsawg rau ob sab thiab qhov kub siab ntawm ob sab: 165-190 ° C;
(3) Qhov kev teeb tsa ntawm lub taub hau kub yuav tsum tsis txhob siab dhau thiab dhau qhov ua tsis zoo ntawm PVC, uas yuav ua rau cov khoom ua kom poob qis. Tom qab ntsuas qhov ntsuas kub nce tus nqi, nws ruaj khov rau li 30 feeb txog 1 teev;
4. Qhib lub cav pub khoom noj thiab lub tshuab hluav taws xob tswj kev tswj, txais yuav kev tshaib kev nqhis thiab qhov sib txig sib txig nrog ceev, qhov kev pub noj ceev yog 5r / min, thiab tus tswj tuav ceev yog 5-6r / min;
5 Tom qab cov khoom ntws tawm tawm ntawm cov tuag lub siab, kho qhov pub mis thiab nrawm ntawm tus tswv tsev kom ncav cuag tus nqi teev nyob rau tib lub sijhawm. Kev pub noj ceev yog 26-27r / min. Qhov ceev ntawm tus tswj tuav yog 14-15r / min. Tus tswv tsev tam sim no yog li ntawm 105A.
Rau kev tsim cov kab npuas PVC ua npuas, peb yuav tsum npaj kom ua ntej. Qhov tseeb, tsis yog nyob rau qhov no nkaus xwb, peb kuj yuav tsum npaj ua kom haum thaum ua lwm yam haujlwm, kom peb tuaj yeem ua haujlwm ntau dua ntawm kev nce qib, yog li peb tau npaj los xyuas kom meej tias peb cov khoom lag luam khiav tau zoo.
