Iyo tembiricha yeVicat inoyera sei kupisa kweiyo UPVC pombi & vharafu?...
Iyo yekushanda tembiricha muganho weupvc vharafu, pombi ndeye 0-70 ℃. Tembiricha yakajairika yakakodzera kushanda kweUPVC zvinhu. kana tembiricha yekushanda ichiwedzerwa, chiyero chesimba rekumanikidza kwemukati chinofanira kuderedzwa. Chiyero chekupikiswa kwekumanikidza pasi petembiricha dzakasiyana-siyana inoratidzwa mutafura inotevera sereferensi.
Hukama pakati pekushanda tembiricha yeUPVC valve pombi uye kumanikidza kuramba:
Kushanda tembiricha | 20 | 25 | 30 | 40 | 50 | 60 |
pressure ratio | 100 | 95 | 85 | 65 | 35 | 10 |
UPVC pombi kupisa kupisa mune chaiyo bvunzo ine yakakosha bvunzo nzira inova Vicat inopfavisa tembiricha bvunzo. Tevere tinosuma chinangwa chebvunzo iyi uye nzira dzekuyedza.
01 bvunzo chinangwa: UPVC vharafu pombi iri nyore kukanganisa mushure mekupisa, kune tembiricha yeVicat kuyera kupisa kwepombi uye vharafu.
02 Midziyo yekuyedza: Vicat yekuyedza muchina
03 bvunzo tsananguro:
(1) mufananidzo unoiswa mune yemvura svikiro, pasi peiyo isothermal tembiricha inokwira kuona yakajairwa kudzvanywa tsono (muchinjiko-chikamu nharaunda ye1mm2) pasi pekuita kwe50 N simba, yakatsikirirwa mumuenzaniso lmm kana tembiricha, ndiko kuti, muenzaniso weVicat Softening Temperature ( VST ).
(2) Vicat inonyorovesa tembiricha ndeye kuongorora kupisa kwekupisa kwezvinhu, zvichiratidza zvemuviri uye zvemagetsi zvimiro zvezvigadzirwa mumamiriro ekupisa eimwe yezviratidzo.
(3) Iyo yakakwirira yeVicat inonyorovesa tembiricha, zviri nani kugadzikana kwedimensional yechinhu kana ichiiswa mukupisa, iyo idiki iyo yekupisa deformation, kureva, zviri nani kupisa deformation kuramba.
(4) nyika mureza zvinodiwa kuti PVC-U mvura pombi pombi Vicat softening tembiricha ≥ 80 ℃, isu Chuanli Plastics Co., Ltd. kugadzirwa mvura kugovera maindasitiri kemikari vharafu pombi Vicat tembiricha iri kazhinji 82 ~ 83 ℃. Drainage pombi zvinhu munyika mwero zvinodiwa Vicat kupfavisa tembiricha ≥ 79 ℃, isu chuanli Plastics Co., Ltd. kugadzirwa PVC-U drainage pombi Vicat kupfavisa tembiricha kazhinji 80 ~ 81 ℃.
