Polypropylene Medical grade hehee i puhi i ka lole mea PP S2040
Hōʻike huahana
ʻO ka polypropylene homopolymer he polymer i hana ʻia e ka polymerization o propylene monomer wale nō.ʻO ka polypropylene homopolymer he polymer semi crystalline.Ma muli o kona crystallinity kiʻekiʻe, homopolymer polypropylene loaʻa nā waiwai mechanical maikaʻi loa.Me ka rigidity kiʻekiʻe, ka ikaika tensile kiʻekiʻe, ka pale wela maikaʻi a me ka deformation.I ka manawa like, no ka maikaʻi o ka wai, ʻoi aku ka nui o ka crystallization kiʻekiʻe i ka pōʻai o nā huahana.Hoʻohana nui ʻia ka Homopolymer polypropylene i ka injection, ke kaha kiʻi a me nā kaʻina hana ʻē aʻe.

Nā noi
Ka laulā noi o ka homopolymer polypropylene:
1. Extrusion molding: paipu, papa, pepa, etc.
2. Injection molding: nā ʻano pahu a me nā mea pono, e like me nā pahu meaʻai, nā mea hana hale, nā pūpū hale, etc.
3. Thermoforming: nā kīʻaha papa ʻaina, me nā pahu ʻaina awakea, nā kīʻaha a me nā pā, nā kīʻaha inu, etc.
4. Kiʻiʻoniʻoni: Homopolymer polypropylene kiʻiʻoniʻoni he aniani a ʻālohilohi, me ka liʻiliʻi o ka permeability i ka mahu wai, me ke kiʻi ʻoniʻoni ʻoniʻoni, hoʻolei kiʻi ʻoniʻoni, bidirectional extension film, etc.
5. Ke kaha kiʻi: hiki ke hana ʻia ka wili pālahalaha me ka liʻiliʻi liʻiliʻi, a hiki ke hana ʻia ka wili hui a me ka lole i ulana ʻole ʻia me ka wai kiʻekiʻe.
ʻO ka fiber ka mākeke nui no ka polypropylene.Hiki ke hoʻonui i ka ikaika tensile ma ka 15 mau manawa o ka hoʻolōʻihi ʻana a i ʻole ka orienting.ʻO nā huahana silika, me nā lole, nā diapers a me nā nonwovens, ʻo ia ka mea nui no ka hana ʻana i nā masks lapaʻau Lako ʻili, ʻeke mahiʻai, nā kaula, nā lole uhi papahele a me nā kāʻei.Kāpena a me ka pehu hope kauhale.Hiki ke hoʻolei ʻia ʻo PP a i ʻole kuhikuhi ʻia i loko o nā kiʻiʻoniʻoni.Hiki ke hoʻohana ʻia nā kiʻiʻoniʻoni kuhikuhi e like me ka paka.Hoʻopili i nā mea no ka lole a me nā ʻatikala he nui;Hoʻohana ʻia ke kiʻiʻoniʻoni nonoriented no nā capacitors a i ʻole nā mea hoʻopihapiha hoʻohana ʻia ka pepa PP e hana ai i nā ipu meaʻai thermoforming, a ʻo kāna mau moisture-proof, hoʻoili kinoea a me nā mea hoʻoili ʻala pono e hoʻokō me nā lula FDA.
