Ekusetyenzisweni kwe-polypropylene fiber spinning, ukusetyenziswa kwepolyethylene waxkulinganiselwe.Kwiintsinga eziqhelekileyo ze-denier kunye neentsinga ezikumgangatho ophezulu, ngakumbi uboya obuthambileyo obufana ne-denier ecikizekileyo kunye neentsinga ze-BCF ezifanelekileyo kwipaving kunye needyasi ezilukiweyo, i-polypropylene wax ikholisa ukukhetha kunewax yepolyethylene.
Sainuo eliphezulu-ubunyulupolypropylene wax, i-viscosity ephakathi, indawo ephezulu yokunyibilika, i-lubricity elungileyo, kunye ne-dispersibility efanelekileyo.Okwangoku iluncedo olugqwesileyo lokusetyenzwa kwe-polyolefin, ukumelana nobushushu obuphezulu, kunye nokusebenza okuphezulu.

Okokuqala, ngenxa yokungahambelani phakathi kwe-polypropylene kunye ne-polyethylene, kunzima kakhulu ukwenza ukuxuba okufanayo kwi-micro sense, eya kubangela ukuhlukana kwesigaba.
Okwesibini, ngenxa yokuba indawo yokunyibilika kwe-wax ye-polyethylene iphantsi kakhulu kune-polypropylene okanye i-polypropylene wax, kunzima ukujongana neempawu zokunyibilika kwee-polymers ezimbini.Ukungalingani kunye ne-rheology engafanelekanga yemveliso kunokukhokelela ekuqhekekeni kokuphela kwenkqubo yokujikeleza.Ngenxa yezi ziphumo ebezingalindelekanga, iipropathi ze-textile ezilukiweyo zefiber ziba mandundu.
Ngeli xesha, kuyimfuneko ukusebenzisa i-polypropylene wax kunye ne-viscosity ephantsi.Ngenxa ye-viscosity yayo ephantsi kunye nokumanzisa kakuhle, inokumanzisa i-pigment ngexesha elifutshane.Ukongeza, xa uzobe kwaye ubeka ubushushu be-polypropylene fiber, inokufumaneka kwiqondo lokushisa lokushisa (ngokuqhelekileyo malunga ne-130c), elingaphakathi nje kwiqondo lokushisa elinyibilikayo le-polyethylene wax.
Ngenxa yotshintsho lwesakhiwo sekristale se-polypropylene ifayibha yokuqala, kunokubonwa ukuba i-polyethylene wax etyhidiweyo ingena kumphezulu wefiber ukusuka kwi-polypropylene matrix, kwaye kungekuphela nje i-wax ecocekileyo, kodwa kunye ne-pigment iya kuziswa phezulu.

Ekugqibeleni, ukuhambelana phakathi kwe-polypropylene wax kunye ne-polypropylene resin ilungile kuzo zombini iinkalo ezincinci kunye ne-macro, kwaye inefuthe elincinci kwiipropati zoomatshini.Kukho iindidi ezimbini ze-polypropylene wax eyenziwe nge-metallocene catalytic technology: enye yi-homopoly polypropylene wax, kunye nempahla eluhlaza yipropylene;Enye yi-copolymerized polypropylene wax, esebenzisa ipropylene kunye ne-ethylene njengemathiriyeli ekrwada.
Ngokubanzi, i-homopolypropylene wax inendawo yokunyibilika ephezulu phakathi kwe-140-160c, ubunzima bemolekyuli ukusuka kumawaka ukuya kumashumi amawaka, i-viscosity ye-Brookfield ehambelanayo ukusuka kwishumi elinesibini ukuya kuninzi olomileyo, ubucwebe obuphezulu kunye nobunzima obuphezulu.Indawo yokunyibilika ye-copolymerized polypropylene wax idla ngokuba phakathi kwe80-110 ℃, i-viscosity yaseBrookfield ngamakhulu ukuya kumawaka okanye amashumi amawaka, kwaye ubunzima bemolekyuli obuhambelanayo bungamawaka ukuya kumashumi amawaka.Ngenxa yokongezwa kwe-ethylene comonomer kwi-polypropylene e-copolymerized, ephazamisa ukucwangciswa rhoqo kweemolekyuli zepropylene, i-crystallinity ye-polypropylene e-copolymerized iphantsi kwaye indawo ethile yokunyibilika iphantsi.
Kwinqanaba lokumanzisa i-pigment, ukumanzisa kwe-viscosity ephantsi kwenzeka ngokukhawuleza kwaye ukusebenza kakuhle kokumanzisa kuphezulu.Kodwa iyafuneka kwi-extrusion yocingo.Kwinqanaba le-granulation, sinethemba lokuba i-wax ine-viscosity ethile, enokuthi idlulise kakuhle i-shear force phakathi kwe-pigment kunye ne-resin enyibilikayo, ukuze i-pigment emanzi ihanjiswe ngokulinganayo kwi-resin melt.Ngeli xesha, kunokuthi kuthathelwe ingqalelo ukusebenzisa i-polypropylene wax enendawo encibilikayo ephantsi kunye ne-polypropylene wax ene-viscosity ephezulu, ukuze kufezekiswe eyona nto intle yokusasazeka.
