He aha ngā paerewa kei ASTM D446, ISO 3105, IP 71, me BS e takotoria ana?

He aha ngā paerewa kei ASTM D446, ISO 3105, IP 71, me BS e takotoria ana?

Me whakarātike i ngā taunakitanga me ngā tohutohu whakamahi mō ngā wipirimiti kapiahi kīriki kia taea ai te tātai i te pākiri kinematic o ngā riquid Newtonian māmārangi, e ai ki ASTM D445, ISO 3104, me IP 71. Mēnā kāore ēnei taunakitanga me ngā tohutohu whakamahi, ka tino hinga te āhua o te pākiri kinematic e kōrerotia ana i ngā tikanga whakamātau ASTM D445, IP 71 me ISO 3104.

He aha te take me whakamahia ai ngā wipirimiti kapiahi kīriki e tukuna mai ana e ZONWON?

Ko ZONWON te whai rawa i te tauira katoa o ngā wira kapihana karaihe. Ko ngā wira kapihana karaihe a ZONWON i hangaia kia ū ki ngā paerewa ārahi rānei e hiahiatia ana e ngā umanga paerewa ā-ao tae atu ki te ASTM D446, ISO 3105, IP 71, me te BS 188. Ko ngā paerewa mātaiwhiuwhiu e whakamahia ana hei tika mātai i ngā wira kapihana karaihe he ISO 17025 ramarua ramarua mō te mātaiwhiuwhiu hoki, mō te nekeneke hoki. Ko ZONWON te whai rawa i ngā wira kapihana karaihe ēnei: BS/IP/RF U-tube reverse flow, BS/U-tube, BS/IP/MSL, BS/U/M Miniature U-tube, Cannon-Fenske opaque, Cannon-Fenske routine, Cannon-Manning semi-micro, BS/IP/SL(S), BS/IP/SL, Ubbelohde, Cannon Ubbelohde, Cannon Ubbelohde dilution, me ngā wira kapihana Cross-arm. Ki te pūrua tētahi tiwhikete mātaiwhiuwhiu ngā wira kapihana karaihe katoa.

Ki te toro atu ki tō mātou toa ipurangi kia riro ai i a koe ngā utu, me ngā mōhio hakinakina mō ngā taputapu Ostwald kua rerekētia, ngā taputapu āhuata, me ngā taputapu capillary kapia hiko kapi rere-kei-tawhiti e arataki ana ki te ASTM D446, ISO 3105, IP 71, me te BS 188 hei whakatau i te pākiki kinematic o ngā wai koiora parahaki.

ASTM D446 & IP71

Ko ēnei whakaritenga i roto i te ASTM D446, ISO 3105, IP 71, me te BS 188 e horapa ana i ngā tohutohu whakamahi mō ngā taputapu capillary kāpia kinematic o ngā momo katoa e whakaahuatia ana mā te taipitopito mō ngā taputapu Ostwald kua rerekētia, ngā taputapu āhuata, me ngā taputapu rere-kei-tawhiti. Anō hoki, ka whakaahuatia te whakarāwekenga o ngā taputapu capillary kāpia. Ko ēnei whakaritenga e horapa ana i ētahi taputapu capillary kāpia e mōhiotia ana, e tino pai ana mō te whakamahi i ngā tikanga whakamātau ASTM D445, IP 71 me ISO 3104 hei whakatau i te pākiki kinematic o ngā wai koiora parahaki.
