Hauv daim ntawv thov ntawm polypropylene fiber ntau spinning, kev siv ntawm polyethylene wax yog txwv. Rau cov khoom zoo tib yam denier txhob lo lo ntxhuav thiab cov fibers zoo, tshwj xeeb tshaj yog rau cov ntaub mos mos zoo li cov denier zoo thiab BCF filaments haum rau paving thiab textile khaub ncaws, polypropylene siv quav ciab feem ntau nyiam rau polyethylene wax.

Ua ntej tshaj plaws, vim qhov tsis sib haum xeeb ntawm polypropylene thiab polyethylene, nws yog qhov nyuaj heev los tsim kev sib xyaw ua ke hauv kev txiav txim siab microscopic, uas yuav ua rau kev sib cais theem. Qhov thib ob, vim hais tias lub melting point ntawm polyethylene siv quav ciab yog ho qis dua li ntawm polypropylene los yog polypropylene wax, nws yog ib qho nyuaj rau hais txog qhov sib txawv melting yam ntxwv ntawm ob polymers. Qhov tsis sib xws thiab tsis tsim nyog rheology ntawm cov khoom tuaj yeem ua rau qhov kawg tawg ntawm cov txheej txheem spinning. Vim cov kev mob tshwm sim no, cov khoom siv ntawm lub cev ntawm cov fiber ntau dhau los.
Nyob rau lub sijhawm no, nws yog ib qho tsim nyog yuav tsum siv cov khoom siv polypropylene nrog cov viscosity tsawg. Vim nws tsis tshua muaj viscosity thiab zoo wettability, nws tuaj yeem ntub cov xim hauv lub sijhawm luv. Tsis tas li ntawd, thaum polypropylene fiber yog ncab thiab kub txheej, nws tuaj yeem pom los ntawm kev kho cua sov (feem ntau txog 130c), uas tsuas yog nyob rau hauv qhov kub ntawm qhov kub ntawm polyethylene wax.

Vim yog qhov hloov pauv ntawm cov qauv crystalline ntawm polypropylene thawj fiber ntau, nws tuaj yeem pom tias molten polyethylene wax seeps los ntawm polypropylene matrix mus rau fiber ntau nto, thiab nws tsis yog tsuas yog ntshiab ciab, tab sis kuj pigment yuav raug coj mus rau saum npoo.
Thaum kawg, kev sib raug zoo ntawm polypropylene wax thiab polypropylene resin yog qhov zoo nyob rau hauv ob qho tib si micro thiab macro, thiab tsis tshua muaj kev cuam tshuam rau cov khoom siv kho tshuab. Muaj ob hom polypropylene wax polymerized los ntawm metallocene catalytic technology: ib qho yog homopolymer polypropylene wax, thiab cov khoom siv raw yog propylene; Lwm qhov yog copolymerized polypropylene wax, uas yog ua los ntawm propylene thiab ethylene.
Feem ntau, homopolymer polypropylene wax muaj lub siab melting point, nyob nruab nrab ntawm 140-160c, molecular hnyav los ntawm ntau txhiab mus rau kaum txhiab, coj Brookfield viscosity los ntawm kaum rau txhiab, siab crystallinity thiab siab hardness. Lub melting point ntawm copolymer polypropylene wax feem ntau yog nyob nruab nrab ntawm 80-110c, lub viscosity ntawm Brookfield yog pua pua mus rau txhiab los yog kaum txhiab, thiab qhov sib thooj molecular hnyav yog ntau txhiab mus rau kaum txhiab. Vim yog qhov sib ntxiv ntawm ethylene comonomer hauv polypropylene copolymer, uas cuam tshuam qhov kev npaj ntawm propylene molecules tsis tu ncua, crystallinity ntawm polypropylene copolymer yog tsawg, yog li lub melting point kuj tsawg.

Nyob rau hauv lub pigment wetting theem, tsawg viscosity wax wetting tshwm sim sai, thiab cov wetting efficiency yog siab dua. Tab sis nws yuav tsum tau nyob rau hauv hlau extrusion. Nyob rau hauv lub granulation theem, peb kuj cia siab hais tias cov wax muaj ib tug viscosity, uas yuav zoo hloov lub shear quab yuam ntawm cov xim thiab resin yaj, yog li ntawd lub wetted pigment yuav muab sib npaug zos faib nyob rau hauv resin yaj. Nyob rau lub sijhawm no, polypropylene wax nrog qis melting point thiab polypropylene wax nrog siab viscosity tuaj yeem siv ua ke kom ua tiav qhov zoo tshaj plaws dispersion.
