Pehea e ana ai ka wela Vicat i ka pale wela o ka paipu UPVC a me ka pahu?,

ʻO ka palena wela o ka upvc valve, paipu he 0-70 ℃. He kūpono ka mahana maʻamau no ka hana ʻana i nā mea UPVC. inā hoʻonui ʻia ka mahana hana, pono e hoʻemi ʻia ka ratio o ka ikaika o loko. Hōʻike ʻia ka lākiō o ke kūpaʻa puʻe ma lalo o nā wela like ʻole ma ka papa kuhikuhi ma ke ʻano he kuhikuhi.

ʻO ka pilina ma waena o ka wela hana o ka paipu valve UPVC a me ke kūpaʻa paʻa:

ʻO ka pale wela UPVC paipu i ka hoʻāʻo kikoʻī he ala hoʻāʻo kūikawā ʻo ia ka Vicat softening temperature test. A laila hoʻolauna mākou i ke kumu o kēia hoʻokolohua a me nā ʻano hoʻokolohua.

01 kumu ho'āʻo: UPVC valve paipu maʻalahi e deform ma hope o ka wela, i ka Vicat wela e ana i ka wela o ka paipu a me ka pahu.

02 Mea ho'āʻo: Vicat mīkini ho'āʻo

03 wehewehe ho'āʻo:

(1) kau ʻia ka specimen i loko o kahi wai wai, ma lalo o ke ʻano o ka piʻi ʻana o ka mahana isothermal e hoʻoholo ai i ka nila kaomi maʻamau (cross-sectional area o 1mm2) ma lalo o ka hana o 50 N ikaika, kaomi ʻia i loko o ka specimen lmm i ka wā o ka mahana, ʻo ia hoʻi, ʻo Vicat Softening Temperature (VST).

(2) ʻO ka wela hoʻonāwaliwali ʻo Vicat e loiloi i ke kūpaʻa wela o nā mea, e hōʻike ana i nā ʻano kino a me nā mīkini o nā huahana i nā kūlana wela o kekahi o nā mea hōʻailona.

(3) ʻOi aku ka kiʻekiʻe o ka wela hoʻonāwaliwali o Vicat, ʻoi aku ka maikaʻi o ke kūpaʻa ʻana o ka mea i ka wā e wela ai, ʻoi aku ka liʻiliʻi o ka deformation thermal, ʻo ia hoʻi, ʻoi aku ka maikaʻi o ka pale ʻana i ka wela.

(4) 'āina maʻamau koi no ka PVC-U wai lako paipu Vicat softening wela ≥ 80 ℃, mākou Chuanli Plastics Co., Ltd. hana o ka wai hoʻolako 'oihana kime kiwi paipu Vicat wela mea maʻamau 82 ~ 83 ℃. ʻO nā mea maʻamau o ka wai paipu wai e pono ai ʻo Vicat softening wela ≥ 79 ℃, mākou chuanli Plastics Co., Ltd. hana o PVC-U drainage paipu Vicat softening wela maʻamau 80 ~ 81 ℃.
