Polyethylene (PE nyav) yog ib qhov sib txawv ntawm thermoplastic uas tshuaj ntxuav los ntawm kev sib thooj kua ethylene. Nyob rau hauv kev lag luam, nws kuj muaj copolymers ntawm ethylene thiab α-olefins me me. Polyethylene tsis muaj qhov nti, tsis lom, thiab muaj feem ntau xws li wax. Nws muaj kev tu siab zoo txaus siab (theej av tsawg kawg tuaj yeem txog -100~-70°C), muaj kev nyab xeeb zoo, thiab tuaj yeem tiv thaiv kev puav tsaws los ntawm ntau yam acid thiab alkalis (tab sis tsis tuaj yeem tiv thaiv acid uas muaj kev cuam tshuam). Nws tsis tuaj yeem sov los ntawm cov chav sov tshwj xeeb nyob rau teeb liab, muaj kev dab theej av tsawg, thiab muaj kev tiv thaiv hluav taws xob zoo.
Polyethylene tuaj yeem tsim los ntawm kev them tsawv ntau yam thermoplastic thiab muaj ntau qhov siv. Nws tau siv nyob rau kev tsim hluv, kev saj ntsuas khoom, tshuab rooj, kab rooj, lwm txoj kab, kab tshwj xeeb, khoom siv hauv noj no, thiab lwm yam, thiab kuj tuaj yeem siv ua khwv tshwj xeeb rau TV, radar, thiab lwm yam. Hauv qhov ntau yam siv no, ob qhov chaw siv polyethylene ntau tshaj plaws yog rau rooj thiab hluv. Txhawm rau kev pab cuam tsev neeg, kev siv hluv rau kev noj mov, kev lag luam, thiab khoom siv ntau yam, ob qhov chaw no kuj pib hlob ntxig ntxig.
Daim ntawv tso cai hauv xeeb GB/T 1632.3-2010 sau txog kev txheeb xyuas qhov muaj zog ntawm qhov chaw ntxuav polyethylene polymers siv cov viscometer capillary. Lub sijhawm ntawm qhov solvent thiab qhov polyethylene (PE) polymer solution uas muaj peev xwm tshwj xeej raug thiaj li muab thiaj rau 135°C. Qhov viscosity tsawg thiab qhov viscosity nyob hauv ntawv tau muab piav los ntawm cov sijhawm outflow uas tau muab thiaj thiab tus concentration uas paub tag ntawm polyethylene (PE) polymer.
Zhongwang's automatic viscosity measurement system IVS800H pab tau rau kev txheeb xyuas nyob rau hauv Ubbelohde viscometry raws li qhov tseem ceeb. Nws yog siv siv rau kev txheeb xyuas qhov muaj zog ntawm PE copolymers nyob rau hauv sijhawm loj. Lub thawv chaw sample tau muab tso rau hauv sijhawm zoo ib yam kom tsis txhob muaj kev ntxuav, thiab pab tau rau kev siv hluas rau kev ntaus, kev txheeb xyuas, kev saib xyuas, thiab kev saib xyuas. Sijhawm kub: room temperature to 150°C (accuracy ±0.05°C); timing accuracy: 0.001S.
Kev Kuaj
-
Kev Tsim Solution : Xauj duab ntawm polyethylene PE nrog rau kev xauj duab 1/10,000, sau rau hauv daim tshuab sau duab, thiab siv DP25 tshuab tso dej (kev tso dej sib txawv ≤0.1%) los tso cov ntaub ntawv rau hauv daim tshuab sau duab.
-
Kev Siv Duab Ntaub Ntawv : Sau daim tshuab sau duab rau hauv P12 Zhongwang polymer dissolver, thiab siv kev tso siab los siv duab ntaub ntawv raws li tus cwj pwm thiab sijhawm xav tau.
-
Kev Txhim Viscosity : Sau cov chav nyob rau hauv PP duab rau hauv IVS800H daim tshuab nrog rau tus cwj pwm oil bath, pib kev txhim, thiab cov lus teb yuav raug txais nrog rau kev pib.
-
Cov results ntawm test : IVS800H kev txhim viscosity tshuab muaj kev sib piv rau computer, uas tuaj yeem txais cov lus teb nrog rau kev pib thiab sau ntaub ntawv, pab rau kev sib piv ntau yam viscosity data.
-
Tsaus tshuab ntim zauv : Cov kab ntawv viscometer tau raug tso rau hauv lub tank dej tsim khib ntawm qhov viscometer IVS800H, thiab tuaj yeem sau los, tshem tshaib, thiab txuas ntxiv cov dej tsis tas tach tawm lossis tshem tawm.
Cov kev tswj hwm uas siv tau: GB/T 1632.3, SO 1628/3, ASTM D1601, thiab lwm yam.
