Ko te Polyethylene (PE mokowhiti) he rēhina thermoplastic i tīmata ai te polymerization o te ethylene. I te ahumahi, koia hoki ngā copolymer o te ethylene me ngā rahinga iti nei o ngā α-olefins. He kāore te polyethylene i te āhua, kāore hoki he huruhuru, ā, he pērā te anuanu. He pai tana whakapainga ki te pōkai mōrearea (ka taea e ia te iti rawa pea te -100 ~ -70°C), he pai hoki tana pūmahara kimikimi, ā, ka taea e ia te herekenga i te nuinga o ngā tātai me ngā alkalis (engari kāore e taea e ia te herekanga i ngā tātai hauora). Kāore e wareware ana ki ngā paraihe noa i te wāhi noa, he iti te whiwhinga wai, ā, he pai te whakamarumaru i te hiko.
Ka taea te whakareri i te polyethylene mā ngā tikanga hanga mōhini waro noa, ā, he nui ngā whāinga whakamahinga. Ka whakamahia matua hei hanga i ngā pene, ngā taputapu pakete, ngā kōpae, ngā pīpoi, ngā aho takirua, ngā waitohu, ngā mea whakamahi ia rā, me ētahi atu, ā, ka taea anō hoki te whakamahi hei taputapu whakamarumaru taiapa-tere mō ngā TV, ngā radar, me ētahi atu. I roto i ana maha whāinga whakamahinga, ko ngā paraihe me ngā pene ngā āhuatanga tuarua e nui ana te whakamahi i te polyethylene. Ki te tipunga o te whare, o ngā paraihe māra, me ngā momo ahumahi pakete mō kai, mātātoko, me ngā hua umanga, kei te tipu haere ake pea ngā āhuatanga e rua nei.
Ko te tīmata whakaaetia GB/T 1632.3-2010 e whakatau ana i te āhua o te pātata o ngā rautaki PE māmā ki te whakamahi i te kipokipo viscometer. Ka neke haere te wā o waho o te paraihe me te rautaki PE i te 135°C. Ka tātai ai i te pātata iti ake me te pātata ake mai i ēnei wā neke haere, tae atu hoki ki te maha mōhiohia o te PE.
Ko te punaha IVS800H a Zhongwang mō te ine pātata aunoa e whakauru ana i te Ubbelohde viscometry hei matua. Ka whakamahia motuhake mō te whakamātau pātata wera-ite huarahi mō ngā taputapu pērā i ngā PE copolymers. Ka pupuri kōpae tauwā i te kōpae tauira kia kaua rawa he putunga, ā, ka whakatūtia te aunoatanga tonu o te tango tauira aunoa, te whakamātau aunoa, te horoi aunoa, me te horoi aunoa. Te haerenga o te wera: te wera o te rūma ki te 150°C (te pono ±0.05°C); te pono o te wā: 0.001S.
Te Raupapa Whakamātau
-
Te Tīmata i te Rongoā : Pākia te tauira polyethylene PE ki tētahi pākaratia 1/10,000, whakaurua ki te pōtae whakaputa tauira, ka whakamahia he DP25 kaihautū auno (te pono o te whakaputanga ≤0.1%) hei whakawhiti i tētahi mātai kōwhiringa ki roto i te pōtae whakaputa tauira.
-
Te Warewarenga o te Tauira : Whakaurua te pōtae whakaputa tauira ki te P12 Zhongwang kaiwhakaputa pouaka, ka whakamahia te wera iti hei warewarenga i te tauira e ai ki te wero me te wā noho takitahi.
-
Te Whakamātau i te Uhi : Whakaurua te pōtae i te tauira PP ki te paerewa IVS800H me te wero takotoranga hinu kua whakaritea, timata te mātai, ka hohoro te whiwhi i ngā hua whakamātau.
-
Kupu Whakamātau : Ko te punaha whakamātau uhi auno IVS800H e hono ana ki te rorohiko, ka taea te whiwhi auno i ngā hua whakamātau me te pupuri raraunga, e āwhina ana i te tātai rerehua uhi.
-
Te Horoi i ngā Tūpu Viscosity : Ko ngā pūpahi o te tapa kōpiko kei roto i te tatauranga wai maimoatia a-ira o te IVS800H, ā, ka pakaru, ka horo, ka maroke tonu ai me te kore e hiahiatia te whakangao me te wehe.
