Kedu ihe bụ polypropylene? – Ngwongwo, Ngwa na uru nke Polypropylene
Kedu ihe bụ Polypropylene (PP)? Polypropylene bụ polymer thermoplastic mere site na polymerisation nke propylene monomers ma bụrụ otu n'ime ihe ndị a na-ejikarị plastik eme ihe n'ụwa. N'ihi kemịkalụ pụrụ iche na nke anụ ahụ, polypropylene na-anọkwa n'ọnọdụ dị mkpa na ngwa ụlọ ọrụ, ahụike, ụlọ na nkwakọ nri.

Ihe ndị bụ isi nke polypropylene
Kedu ihe bụ polypropylene? N'ihe gbasara usoro kemịkalụ, polypropylene bụ polymer kpụrụ site na mgbakwunye polymerisation nke propylene monomers. Ọdịdị molekụla ya na-enwekarị symmetric ma na-adịkarị n'ụdị nke ọkara kristal.

A bịa n'ihe polypropylene bụ, uru ya kacha pụta ìhè gụnyere okpomọkụ na nguzogide kemịkalụ, yana ọnụ ahịa mmepụta dị ala. Ebe mgbaze dị elu nke polypropylene na-enye ohere iji ya mee ihe na okpomọkụ dị elu na-enweghị nsogbu nke mgbagwoju anya ma ọ bụ agbaze. Nguzogide kemịkalụ ya dị mma na-enye ohere ka polypropylene kwụsie ike ma ghara imebi mgbe ekpughere ya na acid, alkalis na ihe mgbaze organic.
