Isicelo
I-PP (i-polypropylene) induku iyinto e-semi-crystalline evelele ngenxa yenhlanganisela yayo eyingqayizivele yezinto ezibonakalayo nezomshini. Esinye sezici zayo eziphawuleka kakhulu ubulukhuni bayo kanye nephuzu eliphezulu lokuncibilika, okuyenza ihluke kwezinye izinto ezifana ne-PE (i-polyethylene). Nakuba uhlobo lwe-homopolymer lwe-PP lungaba nzima kakhulu uma luchayeka emazingeni okushisa angaphezu kuka-0°C, izinto eziningi ze-PP zokuhweba zenziwe njengama-copolymer angahleliwe noma ama-clamp copolymer anamaphesenti ahlukahlukene e-ethylene.
Ama-copolymers angahleliwe ngokuvamile aqukethe i-ethylene engu-1 kuya ku-4%, kuyilapho ama-clamp copolymer anesilinganiso esiphezulu se-ethylene. Le nqubo ye-copolymerization iphumela kumpahla ye-PP enezinga lokushisa eliphansi lokuhlanekezela ukushisa (100°C) uma liqhathaniswa ne-homopolymer PP. Yize into ye-copolymer yohlobo lwe-PP ingaba nokucaca okuphansi, isicwebezelisi, nokuqina, ibonisa amandla omthelela anamandla. Njengoba okuqukethwe kwe-ethylene ku-copolymer kwanda, amandla aphelele wezinto ze-PP nawo ayanda, okwenza kube inketho eguquguqukayo yezinhlelo zokusebenza ezihlukahlukene.
Esinye isici esibalulekile se-PP izinga lokushisa layo lokuthambisa i-Vicat, elingu-150°C. Lokhu kumelana nokushisa okuphezulu, kuhlanganiswe nezinga eliphakeme le-crystallinity yezinto ezibonakalayo, kubangela ukuqina okuhle kakhulu kwendawo kanye nokumelana nokunwaya. Lezi zakhiwo zenza i-PP ibe inketho efanelekile yezinhlelo zokusebenza lapho ukuqina nokumelana nokuguga nokudilika kubalulekile.
Ngaphezu kwalokho, i-PP yaziwa ngokumelana kwayo nokuqhekeka kokucindezeleka kwemvelo, okuyinkinga evamile kwezinye izinto eziningi. Lokhu kukwenza kube ukukhetha okuthembekile ukusetshenziswa ezindaweni lapho ukuchayeka kumakhemikhali, umswakama, noma ezinye izinto ezicindezelayo.
Ngaphezu kwezakhiwo zayo zemishini, i-PP iphinde inikeze ukucutshungulwa okuhle kakhulu. Ingabunjwa kalula futhi yakhiwe kusetshenziswa izinqubo ezahlukahlukene zokukhiqiza, njengokubunjwa komjovo, ukukhishwa, kanye nokubunjwa kokushaywa. Lokhu kuguquguquka, kuhlanganiswe nezinye izakhiwo zayo, kwenza i-PP ibe yisinqumo esidumile ezinhlobonhlobo zezinhlelo zokusebenza, okuhlanganisa ukupakisha, izingxenye zezimoto, nemikhiqizo yabathengi.
Sekukonke, induku ye-PP iyinto eguquguqukayo futhi ehlala isikhathi eside enikeza inhlanganisela eyingqayizivele yezakhiwo zomzimba nezomshini. Iphuzu layo eliphakeme lokuncibilika, ukuqina kobuso obuhle kakhulu nokumelana nokuklwebheka, kanye nokumelana nokuqhekeka kokucindezeleka kwemvelo kuyenza ibe inketho ekahle ezinhlobonhlobo zezinhlelo zokusebenza. Kungakhathaliseki ukuthi ufuna into engakwazi ukumelana namazinga okushisa aphezulu, imelane nokuguga, noma kokubili, i-PP rod iyindlela ethembekile neguquguqukayo eqinisekile ukuhlangabezana nezidingo zakho.
