I-Chain extender iwuhlobo lwempahla enganweba iketango lamangqamuzana futhi ikhulise

isisindo samangqamuzana ngokusabela neqembu elisebenzayo kuchungechunge lwe-polymer ewumugqa.

Ngokuvamile esetshenziselwa ukuthuthukisa izakhiwo mechanical kanye processing izakhiwo

i-polyurethane, i-polyester, inayiloni neminye imikhiqizo.

I-Epoxy chain extender iyiketango le-extender eliqukethe i-glycidyl methacrylate (GMA) .

Izandiso zeketanga le-epoxy ezisetshenziswa kakhulu zifaka i-styrene-glycidyl methacrylate, enayo

Ukuzinza okuhle kwe-thermal futhi kungabhekana nokuphendula kwamakhemikhali okuvula indandatho nge-PA6, kunokuba

ukuxuba okuhlanzekile ngokomzimba.Ingasetshenziswa futhi ekugayweni kabusha kwe-PET nezinye izici.I

umsebenzi we-epoxy chain extensions kwinayiloni eguquliwe umi kanje:

1. Umphumela wesisindo samangqamuzana kanye ne-viscosity yangaphakathi

Izandiso ze-epoxy chain zingasabela neqembu lokugcina le-amino kanye neqembu lokugcina le-carboxyl

PA6, bese uthuthukisa isisindo samangqamuzana e-PA6.Nokho, i-gelation kungenzeka ngesikhathi

ukusabela kwesandiso seketango, ngakho-ke kuyadingeka ukulawula izimo ezifanele, ikakhulukazi

izinga lokushisa nesivinini sesikulufu, ukuvimbela ukuxhumanisa ku-extrusion esebenzayo.

I-viscosity yangaphakathi ye-PA6 inyuke ngokushesha ngokunyuka kwenani leketango

extender.Lapho okuqukethwe kwe-chain extender kukhuphukela engxenyeni ethile enkulu, i

i-viscosity yangaphakathi ye-PA6 yehle kancane.Lokhu kungenxa yokuthi iqembu letheminali le-PA6 lingakwazi

sabela ngokushesha ngeqembu le-epoxy ku-chain extender ngenxa ye-polarity ne-hydrogen

isibopho.Uma inani le-chain extender limaphakathi, ingxenye yeketango elide

ama-molecule ohlelweni ayanda futhi i-viscosity iyanda ngokufanele;

Nokho, njengobaukusabela kuyaqhubeka, okuqukethwe kweqembu lokugcina le-PA6 kuncipha, kanye nokushayisana

okungenzeka kuukuphela kweketango lamangqamuzana kuyancipha kakhulu ngenxa yethonya le

ukusabalalisa okushisayokanye nobude beketango lamangqamuzana, ngaphezu kwalokho, i-extender yeketanga eliningi kakhulu

kungaholela ekutheni ainani elincane lejeli ohlelweni, okuholela ekwehleni kwesandiso seketango

ukusebenza kahlekanye ne-PA6 intrinsic viscosity.

2. Umphumela ezicini zemishini

Isisindo samangqamuzana esihlobene se-PA6 sinyuswe ngemva kokunwetshwa kweketango ngeketango le-epoxy

extender, Ukuqina kwento bungathuthukiswa ngempumelelo ngokuncipha

crystallinity kanye nosayizi wokusanhlamvu.Ngaphezu kwalokho, ngokwanda kobude beketango lamangqamuzana,

ukubopha phakathi kwamaketanga kuyanda, futhi iketango lamangqamuzana kunzima ukushelela.Ku

ngale ndlela, amandla omthelela angamuncwa ngokushintsha ukucushwa kwe-molecule

chain lapho ithintwa yizwe langaphandle.Kodwa lapho ingxenyana mass of chain extender

idlula ingxenye ethile, zonke izakhiwo zemishini ziyancishiswa./n

3. Umphumela wezakhiwo ze-rheological

I-Melt flow rate (MFR) yehle kakhulu ngokunyuka kwe-epoxy chain extender,

okubonisa ukuthi i-epoxy chain extender kanye ne-PA6 ibe nokusabela okuphumelelayo kwesandiso seketango.

Ngokukhula kwenani le-chain extender, i-torque yokulinganisa inyuke kuqala

bese yehla, ngenxa yokuthi isisindo samangqamuzana esihlobene se-PA6 ngemva kokunwetshwa kweketango

ukwanda, ukuboshwa kweketango lamangqamuzana kwanda, kanye ne-viscosity encibilikayo nayo

ukwanda, ngaleyo ndlela i-torque yokulinganisa iyanda.

Ngokuhamba kwesikhathi, i-PA6 pellet yathamba, yahlanganiswa futhi yancibilika kancane kancane, i

ukumelana kwe-rotor kwehle, futhi i-torque nayo yehla.
