XNR-400C Nnwale ọnụego ịgbaze agbaze

Ihe nnwale: A na-eji iji chọpụta ogo mgbaze nke polyethylene, polypropylene, polyoxymethylene, resin ABS, polycarbonate, nylon fluoroplastics na polymers ndị ọzọ na oke okpomọkụ.

XNR-400C gbazee ọnụego ihe nleba anya bụ ngwá ọrụ maka ịlele njirimara eruba nke polymers rọba na okpomọkụ dị elu dịka usoro nnwale nke GB3682-2018 si dị. A na-eji ya maka polyethylene, polypropylene, polyoxymethylene, resin ABS, polycarbonate, na fluorine naịlọn. Ntụle nke agbaze agbaze nke polymers dị ka plastik na okpomọkụ dị elu. Ọ dabara maka mmepụta na nyocha na ụlọ ọrụ mmepụta ihe, ụlọ ọrụ na ngalaba nyocha sayensị.

MFR na-egosipụta mita ọsọ agbaze (mass), nkeji bụ: gram/10 nkeji (g/min), na usoro a na-egosipụta: MFR (θ, mnom )=tref .m/t
Na usoro: θ—- nwalee okpomọkụ
mnom— ibu ọnụ Kg
