PP ni nyenzo isiyo na kristalini. Ni ngumu na ina kiwango cha kuyeyuka kinachoongezeka kuliko PE. Kwa sababu joto la PP la aina ya homopolymers ni brittle sana inapopita 0 \u00b0 C, nyenzo nyingi za kibiashara PP<\/a><\/strong> ni copolymers za nasibu za 1 hadi 4% ethylene au copolymer ya clamp yenye uwiano mkubwa wa ethylene. Aina ya copolymer ya nyenzo ya PP ina joto la chini la upotoshaji wa joto (100 \u00b0 C), uwazi wa chini, gloss ya chini, ugumu wa chini, lakini ina nguvu ya juu ya athari. Nguvu ya PP inaongezeka kadri maudhui ya ethylene yanavyoongezeka. Joto la Vicat la PP ni 150 \u00b0C. Kwa sababu ya kiwango cha juu cha kristalini, nyenzo hii ina ugumu mzuri wa uso na upinzani wa kupondwa. Hakuna tatizo la kufurika kwa shinikizo la mazingira katika PP. PP kawaida hubadilishwa kwa kuongeza nyuzi za kioo, viongeza metali au goma ya thermoplastic.<\/p>

Kiwango cha mtiririko wa PP kina MFR inayotofautiana kati ya 1 hadi 40. Nyenzo za PP zenye MFR ya chini zina upinzani mzuri wa athari lakini elongation ya chini. Kwa nyenzo zenye MFR sawa, nguvu ya aina ya copolymer ni kubwa zaidi kuliko ile ya aina ya homopolymer. \"Maskin<\/p>

Mchakato wa kutengeneza kwa sindano wa vifaa ni mgumu. Unapochagua ni nyenzo gani bora ya PC ya kutumia, inapaswa kutegemea matarajio ya mwisho ya bidhaa. Ikiwa sehemu ya plastiki inahitaji upinzani wa juu wa athari, basi tumia mtiririko wa chini.<\/p>

Nyenzo za Kinetic PC; kinyume chake, nyenzo za PC zenye kiwango cha mtiririko wa juu zinaweza kutumika kuboresha mchakato wa ukingo wa sindano.<\/p>

PP is a semi-crystalline material. It is harder and has a higher melting point than PE. Since the PP temperature of the homopolymer type is very brittle when it is higher than 0 \u00b0 C, many commercial PP materials are random copolymers of 1 to 4% ethylene or a clamp copolymer of a higher ratio […]<\/p>\n","protected":false},"author":1,"featured_media":490,"parent":0,"template":"","tags":[81],"info-type":[2],"class_list":["post-480","info","type-info","status-publish","has-post-thumbnail","hentry","tag-pp-pe-flake-products-recycling-and-pelletizing-machine","info-type-news"],"taxonomy_info":{"post_tag":[{"value":81,"label":"PP PE flake products recycling and pelletizing machine"}],"info-type":[{"value":2,"label":"Case & News"}]},"featured_image_src_large":["https:\/\/www.recycle-plant.com\/wp-content\/uploads\/2018\/11\/PP-PE-flake-products-recycling-and-pelletizing-machine6.jpg",720,540,false],"author_info":{"display_name":"Ella","author_link":"https:\/\/www.recycle-plant.com\/sw\/author\/admin\/"},"comment_info":"","_links":{"self":[{"href":"https:\/\/www.recycle-plant.com\/sw\/wp-json\/wp\/v2\/info\/480","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.recycle-plant.com\/sw\/wp-json\/wp\/v2\/info"}],"about":[{"href":"https:\/\/www.recycle-plant.com\/sw\/wp-json\/wp\/v2\/types\/info"}],"author":[{"embeddable":true,"href":"https:\/\/www.recycle-plant.com\/sw\/wp-json\/wp\/v2\/users\/1"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.recycle-plant.com\/sw\/wp-json\/wp\/v2\/media\/490"}],"wp:attachment":[{"href":"https:\/\/www.recycle-plant.com\/sw\/wp-json\/wp\/v2\/media?parent=480"}],"wp:term":[{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.recycle-plant.com\/sw\/wp-json\/wp\/v2\/tags?post=480"},{"taxonomy":"info-type","embeddable":true,"href":"https:\/\/www.recycle-plant.com\/sw\/wp-json\/wp\/v2\/info-type?post=480"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
