Ko te polyvinyl chloride (PVC mokowhiti) he pūpahi hangaia e te whakakaha o te monomer vinyl chloride (VCM) ki te āwhina o ngā kaiārahi pērā i ngā peroxides me ngā huinga azo, tērā anō rānei i te ātaahua me te wera ki te arataki o te rāwekenga ira tangata. Ko ngā homopolymer vinyl chloride me ngā copolymer vinyl chloride ka karangatia katoa hei ngota vinyl chloride.
Mā te āhua pai o ana īnanga pērā i te tūponotanga pai, te mātotoru, me te whakamarumaru, ka whakamahia whānuitia te polyvinyl chloride ki ngā ahumahi, hangarau, mahiara, noho tāngata, whakaputanga, hiko, ngā ratonga tūmatanui, me ētahi atu mara.
Ko ngā raraunga mō te tau kīmātai, te uara K, me te rārangi o te polymerization o te polyvinyl chloride ko ngā tohu matua mō te mahi a te hua. Nō reira, ko te whakamātau i te pono me te tūponotanga o ēnei raraunga te kei o te whakahaere kounga mō te polyvinyl chloride.
Tohua mōhio nui GB/T3401-2007 e whakarātō ana i te whakamahinga o te Ubbelohde viscometer hei ine i te tau āhua me te uara K o ngā raihana polyvinyl chloride kua tēkau. I te wā o te whakamātau, ko te wāhi pana iho hohonu e (25±0.5)℃ ana, me pana tonu te wāhi e inea ana i roto i te ±0.05℃ o te wāhi pana iho hohonu.
Ko te IVS400 te matotoru aunoa mai i Hangzhou Zhongwang Technology Co., Ltd. i hangaia ki te Ubbelohde viscosity hei matua, e arataki ana ki ngā tikanga pāwhara pērā i ISO, GB, me DIN. Ka whai ia i tētahi prosihia matotoru aunoa tae atu ki te horoi aunoa, te ine aunoa, te tātai aunoa, te whakaputanga paraikete aunoa, me te maroke aunoa. Ka taea te tika o te wā tata ki te 0.001s. E tuku ana i tētahi marautanga wāhi pana tūpono o ≤±0.01℃ mō te whakamātau, ka tiakina te tika o ngā raraunga whakamātau.
Te Raupapa Whakamātau
-
Te Tīmata i te Rongoā : Pātai i te tauira polyvinyl chloride (PVC) ki te peepi taurite 1/10,000, whakaputia ki te pōtae whakapaeha tauira, ka whakamahi i te DP25 kaihautū aunoa (te pono o te whakapau ≤0.1%) hei whakapā kei te pōtae whakapaeha tauira i te nui kua whakatauhia o te cyclohexanone;
-
Te Warewarenga o te Tauira : Whakaputia te pōtae whakapaeha tauira ki te P12 Zhongwang kaiwhakapahe polimer (ka taea te whakapaeha maha ngā tauira i te wā kotahi), ka whakamahi i te whakatere mātātoko hei whakapaeha i te tauira e ai ki te āhuarangi me te wā kua tohua;
-
Te Whakamātau i te Uhi : Hurihia te IVS400 kaitātari tāpiripiri, tautauhia te āhuarangi o te wāhi wai e hiahiatia ana (25℃±0.01℃), whakapāngia te rongoā ki te Ubbelohde viscometer, hurihia te pūmanawa, ka mahia me te tātai aunoa te tāpiripiri, ā, ka taea te penapena aunoa i ngā raraunga tāpiripiri ki te rorohiko;
-
Kupu Whakamātau : Ko te punaha ine tāpiripiri aunoa IVS400 kua hono ki te rorohiko, e taea ai te whiwhi aunoa i ngā hua tāpiripiri me te penapena raraunga, hei whakawhanaketanga i te tāpiripiri raraunga anuanu.
-
Te Horoi i ngā Tūpu Viscosity : Muri i te whakaputanga aunoa i te para, ka tāpiri reagent whakaparuki mō te whakaparukitanga me te horapa aunoa.
