Vicat kub ntsuas qhov kub tsis kam ntawm UPVC yeeb nkab & valve li cas?
Vicat kub ntsuas qhov kub tsis kam ntawm UPVC yeeb nkab & valve li cas?ua
Kev ua haujlwm kub txwv ntawm upvc valve, yeeb nkab yog 0-70 ℃. Qhov kub thiab txias yog tsim rau kev ua haujlwm ntawm UPVC cov khoom. Yog tias qhov kub thiab txias ua haujlwm tau nce, qhov sib piv ntawm lub zog sab hauv siab yuav tsum tau txo qis. Qhov piv ntawm kev ua haujlwm siab nyob rau hauv ntau qhov kub thiab txias yog qhia hauv cov lus hauv qab no raws li kev siv.
Kev sib raug zoo ntawm kev ua haujlwm kub ntawm UPVC valve yeeb nkab thiab siab tsis kam:
Ua haujlwm kub | 20 | 25 | 30 | 40 | 50 | 60 |
siab piv | 100 | 95 | 85 | 65 | 35 | 10 |
UPVC yeeb nkab kub tsis kam nyob rau hauv qhov kev ntsuam xyuas tshwj xeeb muaj ib txoj kev sim tshwj xeeb uas yog Vicat softening kub ntsuas. Tom ntej no peb qhia lub hom phiaj ntawm qhov kev xeem no thiab cov qauv kev sim.
01 lub hom phiaj kev xeem: UPVC valve yeeb nkab yog ib qho yooj yim rau deform tom qab tshav kub, mus rau Vicat kub los ntsuas qhov kub tsis kam ntawm cov yeeb nkab thiab valve.
02 Cov cuab yeej kuaj: Vicat kuaj tshuab
03 test description:
(1) cov qauv yog muab tso rau hauv cov kua nruab nrab, nyob rau hauv cov xwm txheej ntawm isothermal kub nce los txiav txim siab tus qauv siab koob (hli-sectional cheeb tsam ntawm 1mm2) nyob rau hauv qhov kev txiav txim ntawm 50 N quab yuam, nias rau hauv cov qauv lm thaum kub, uas yog, tus qauv Vicat Softening Temperature (VST).
(2) Vicat softening kub yog los ntsuas qhov kub tsis kam ntawm cov ntaub ntawv, qhia txog lub cev thiab lub zog ntawm cov khoom hauv cov cua sov ntawm ib qho ntawm cov ntsuas.
(3) Qhov siab dua ntawm Vicat softening kub, qhov zoo dua qhov kev ruaj ntseg ntawm cov khoom thaum raug tshav kub, qhov me dua thermal deformation, piv txwv li, qhov zoo dua qhov kub deformation kuj.
(4) lub teb chaws tus qauv yuav tsum tau rau PVC-U dej mov yeeb nkab Vicat softening kub ≥ 80 ℃, peb Chuanli Plastics Co., Ltd. zus tau tej cov dej muaj tshuaj valve yeeb nkab Vicat kub yog feem ntau 82 ~ 83 ℃. Cov khoom siv hauv lub teb chaws tus qauv yuav tsum Vicat softening kub ≥ 79 ℃, peb chuanli Plastics Co., Ltd. zus tau tej cov PVC-U cov kav dej Vicat softening kub yog feem ntau 80 ~ 81 ℃.
