XNR-400C Rere Rere Whakamatau

Nga mea whakamatautau: Ka whakamahia hei whakatau i te reiti rere whakarewa o te polyethylene, polypropylene, polyoxymethylene, ABS resin, polycarbonate, nylon fluoroplastics me etahi atu waerau i te wera nui.

Ko te XNR-400C te whakamaarama rerenga rerenga he taputapu mo te ine i nga ahuatanga rere o nga polymers kirihou i nga wera teitei e ai ki te tikanga whakamatautau o GB3682-2018. Ka whakamahia mo te polyethylene, polypropylene, polyoxymethylene, ABS resin, polycarbonate, me te nylon fluorine. Ko te inenga o te rere rewanga o nga polymers penei i nga kirihou i nga wera teitei. He pai mo te whakaputa me te rangahau i roto i nga wheketere, umanga me nga waahanga rangahau pūtaiao.

2. Te kaha whakamatautau paerewa (taumata waru)
Taumata 1: 0.325 kg = (rakau piston + paepae taumaha + ringaringa wera wera + 1 tinana taumaha) = 3.187N
Taumata 2: 1.200 kg=(0.325+0.875 taimaha Nama 2)=11.77 N
Taumata 3: 2.160 kg = (0.325 + Nama 3 1.835 taumaha) = 21.18 N
Taumata 4: 3.800 kg=(0.325+No. 4 3.475 taumaha)=37.26 N
Taumata 5: 5.000 kg = (0.325 + Nama 5 4.675 taumaha) = 49.03 N
Taumata 6: 10.000 kg=(0.325+No. 5 4.675 taumaha + Nama 6 5.000 taumaha)=98.07 N
Taumata 7: 12.000 kg=(0.325+No. 5 4.675 taumaha+No. 6 5.000+No. 7 2.500 taumaha)=122.58 N
Taumata 8: 21.600 kg=(0.325+0.875 taimaha o Nama 2+1.835 taimaha o Nama4+3.475+No.5 4.675+No.6 5.000+No.7 2.500+No.8 2.915 taumaha)=211.82 taimaha hapa whanaunga ≤ 0.5%.
3. Te awhe pāmahana: 50-300 ℃
4. Tika tonu te pāmahana: ± 0.5 ℃.
5. Tuku hiko: 220V±10% 50Hz
6. Nga tikanga taiao mahi: ko te 10 ℃-40 ℃ te pāmahana ambient; te haumākū whanaunga o te taiao ko 30%-80%; karekau he reo kino huri noa, karekau he hau kaha; karekau he wiri huri noa, karekau he wawaotanga autō kaha.

Te hanganga me te kaupapa mahi:
Ko te mita rere rewanga he mita kirihou kua puta. Ka whakamahia e ia he oumu whakawera teitei kia eke te mea ine ki te ahua whakarewa i raro i te ahuatanga o te pāmahana kua tohua. Ko te ahanoa whakamatautau i roto i tenei ahua whakarewa ka tukuna ki te whakamatautau tangohanga ma te kohao iti o tetahi diameter i raro i te taumaha o te taumaha kua tohua. I roto i te hanga kirihou o nga umanga ahumahi me te rangahau o nga waahanga rangahau pūtaiao, ko te "whakarewa (papatipu) reiti rere" he maha nga wa e whakamahia ana hei whakaatu i nga ahuatanga tinana o nga rauemi polymer i roto i te ahua whakarewa penei i te wai me te viscosity. Ko te taurangi rewa e kiia nei ko te taumaha toharite o ia waahanga o te extrudate kua huri ki te rōrahi tangohanga o te 10 meneti.
Ko te mita reiti rerenga (papatipu) e whakaatuhia ana e te MFR, ko te waeine ko: karamu/10 meneti (g/min), ko te tauira e whakaatu ana: MFR (θ, mnom )=tref .m/t
I roto i te tātai: θ—— te pāmahana whakamātautau
mnom— nominal load Kg
m —— te papatipu toharite o te tapahi g
tref —— wa tohutoro (10min), S (600s)
T —— tapahia te waahi wa s
Tauira: Ka tapahia he huinga tauira kirihou ia 30 hēkona, ko nga hua papatipu o ia wahanga: 0.0816 g, 0.0862 g, 0.0815 g, 0.0895 g, me te 0.0825 g.
M Wawaenga = (0.0816+0.0862+0.0815+0.0895+0.0825)÷5=0.0843(g)
Whakakapihia ki te tauira: MFR=600×0.0843/30=1.686 (g/10 meneti)
Ko tenei taputapu he oumu whakamahana me te punaha whakahaere pāmahana, ka whakauruhia ki te turanga o te tinana (tīwae).
Ko te waahanga mana o te pāmahana e mau ana i te mana rorohiko maramara kotahi me te tikanga whakahaere pāmahana, he kaha te kaha ki te aukati i te aukati, te tika o te mana o te pāmahana, me te mana pumau. Ko te waea whakawera i roto i te oumu ka werohia ki runga i te rakau whakamahana i runga i tetahi ture hei whakaiti i te rōnaki pāmahana ki te whakatutuki i nga whakaritenga paerewa.
