Edge ultra sonic akara welded foldable ọnụ ahịa ụlọ ọrụ na-echebe osisi PP Corrugated Corflute Tree Guard

Ụdị PP nke copolymer nwere obere okpomọkụ mgbagha (100 Celsius C), nghọta dị ala, obere gloss, obere siri ike, mana nwere mmetụta siri ike karị. Ike nke PP na-abawanye na ọdịnaya ethylene na-abawanye. Vicat dị nro na-ekpo ọkụ nke PP bụ 150 ° C. N'ihi ogo dị elu nke kristal, ihe a nwere ezigbo nkwụsi ike elu na ihe mgbochi ọkọ. PP enweghị nsogbu mgbawa gburugburu ebe obibi. Dịka, a na-agbanwe PP site na ịgbakwunye eriri iko, ihe mgbakwunye ígwè ma ọ bụ roba thermoplastic. Ọnụego MFR nke PP sitere na 1 ruo 40. Ihe PP nwere obere MFR nwere mmetụta dị mma karịa ma ọ bụ obere ductility. Maka otu ihe MFR ahụ, ike nke ụdị copolymer dị elu karịa nke ụdị homopolymer. N'ihi crystallization, shrinkage ọnụego nke PP bụ nnọọ elu, n'ozuzu 1.8 ~ 2.5%. Na ntụziaka ntụziaka nke shrinkage dị nnọọ mma karịa nke PE-HD na ihe ndị ọzọ. Ịtinye ihe mgbakwunye iko 30% nwere ike ibelata mbelata na 0.7%.
