Polypropylene faeba

Polypropylene fiber e entsoe ka propylene polymerization, ho qhibiliha ho qhibilihang, ka lebaka la ho se limolek'hule tsa sehlopha sa polar, matla a limolek'hule a manyane, mme ka lebaka la ketane ea limolek'hule e boreleli haholo, mocheso oa khalase oa phetoho ea polypropylene tlasa 0 ℃, fiber e tlameha ho amohela isotactic polypropylene polymerization, etsa athomo e 'ngoe le e' ngoe ea polypropylene macromolecule le lihlopha sebakeng se le seng e le tlhophiso e tloaelehileng, e ka fihla ho 165-170 70, ntlha e qhibilihang ka lebaka la khoheli ea propylene lipakeng tsa limolek'hule e nyane, kahoo boima ba molek'hule ea polypropylene resin ka 200000 kapa ho feta, qhibiliha e qhibilihang, ka hona, ha mocheso o qhibilihisang mocheso o bilikang o kaholimo ho 100 ℃ ho feta sebaka se qhibilihang, ka kakaretso ke 285 ℃ kapa ho feta. Lethathamo la limolek'hule tsa polypropylene le bonolo ho sebelisoa khafetsa, 'me ho bonolo ho le hlakola nakong ea ho ohla. Ho khanya ha fiber ea mantlha ho fihlela ho 50%. Ha o ohla, mocheso oa kamore ea silika o laoloa ka tlase ho 30 ℃, e le hore faeba ea mantlha e hlahise likristale tsa maiketsetso tse mahlakore a tšeletseng, tse bonolo ho otlolloa nakong ea ts'ebetso ea morao-rao. Ho hlophisoa ha fiber ea polypropylene e mahoashe ho ka sebelisoa lisebelisoa tse tšesaane tsa filimi tse khutšoane, e ntšang filimi e phekotsoeng e nang le li-groove ho roller ho arola fiber. Polypropylene fiber density ke 0,91 g / cm ', ke fiber ea lik'hemik'hale ho latela mefuta, fiber ha e monye mongobo, tlasa maemo a tloaelehileng sekhahla sa mongobo se haufi le 0, ts'ebetso e ommeng le e metsi ea mmuso ntle le phetoho e kholo, ha ho hlobo mme ha ho tshwele. Ka lebaka la ho se hygroscopicity, ho daea ho thata, mokhoa oa ho daea o ohla o ka sebelisoa ho rarolla bothata ba ho daea polypropylene, empa chromatography ha e felle.

Matla a polypropylene fiber le modulus ea mantlha li phahame, haufi le polyester, ho apara ho hanyetsa le ho saroloha ho lokile, empa ha mojaro o eketseha, polypropylene fiber fiber e telele e feta polyester, tlasa khatello ea khatello ea maikutlo le matla a ho robeha e phahametse polyester, kahoo polypropylene fiber ke fiber e matla ebile e thata.

Polypropylene fiber khalase mocheso o tlase haholo, ka hona, mocheso o beha phello ha o tsitsitse. Ntho e nolofatsang ke 140-150 ℃, 'me ntlha e qhibilihisang ke 165-173 ℃. E qhibilihisoa ka lehlakoreng le leng ebe e chesoa butle ka lehlakoreng le leng lelakabeng.

Mocheso o futhumatsang ka fiber ke ts'ebetso e tlase haholo, e ntle ea ho kenya letsoho. Polypropylene ke polasetiki ea ketane ea khabone, ketane ea macromolecular ntle le lihokela tse fokolang, botsitso ba lik'hemik'hale bo botle, ntle le chloric acid, nitric acid le tšenyo e 'ngoe ea asiti ea oxidation, ho hanela li-acid tse ling ho nepahetse. Ho hanyetsa alkali, ntle le soda e matla e bakang,

Alkaline ha e na matla ho polypropylene. Polypropylene e hananang le li-solvents ka kakaretso tse kang ethanol, ethyl ether, benzene, acetone, peterole, tetrachlorethylene ha e qhibilihe ka ho chesa benzene le ho ruruha ha peterole, e ka qhala ka chlorobenzene e chesang, tetrahydronaphthalene le dechydronaphthalene.

Polypropylene fiber e na le ts'ebetso e ntle ea ho kenya motlakase, empa ho bonolo ho bokella motlakase o sa sebetseng ha o sebetsoa, ​​mme ts'ebetso ea fiber e hloekileng ea polypropylene fiber e fosahetse.

Polypropylene fiber e bonolo ho tsofala, hobane athomo ea haedrojene e athomo ea khabone e phahameng ka har'a ketane ea polypropylene macromolecular e sebetsa haholo, e leng bonolo ho angoa ke khanya, mocheso joalo-joalo 'me e hlahisa e sebetsang ntle le tefo, mme e baka ketane ea mahala ea mahala boitšoaro bo hlephileng, bo khothalletsang ho khaoha ha ketane ea macromolecular. Ha likhoele tsa isotactic polypropylene li bolokiloe ho 50 ℃ selemo se le seng, li lahleheloa ke boleng ba tsona. Bakeng sa ho thibela botsofali, ho ohla hangata ho eketsa moemeli oa ho tsofala, molemong oa ho fokotsa ts'ebetso ea botsofali, phello e ntle ea o-hydroxydiphenyl ketone le nikele e nang le metsoako ea tšepe, e eketsang 1% ho 3% graphite ho thibela botsofali e sebetsang ka ho fetisisa, empa e sa tšoanelehe bakeng sa tlhahiso ea fiber e tšoeu.

Polypropylene fiber ka lebaka la theko ea tlhahiso e tlase, palo ea thepa e nyane le e ntlehali ea 'mele le lik'hemik'hale mme e bile le nts'etsopele e potlakileng, ntle le palo e kholo ea ts'ebeliso ea masela a liindasteri, lesela le sa lohiloeng, le eona e ile ea qala ho apara, Haholo-holo ka lebaka la polypropylene fiber e na le karolo ea mantlha ho keneng, e ka sebelisa lesela la capillary mouoane oa metsi ho tsoa, ​​ka boeona ha ho na phello ea ho monya, ho etsa letlalo le omelle, ke la lipapali tse matla tsa tlhahiso, seaparo le lesela le leng la matsoho le sebetsang, jj.
