Ifa kanye Nezinselele Ze-Nylon-66

Ngomhlaka-28 kuNhlolanja 1935, kwaba nempumelelo enkulu kwezesayensi yezinto ezibonakalayo lapho usosayensi waseMelika uWallace Hume Carothers ephumelela ukukhiqiza i-Nylon-66, i-polyamide enezakhiwo eziphawulekayo. Njengoba inezinga eliphezulu lokuncibilika elingu-263°C, ukumelana okungavamile nezinyibilikisi ezivamile, kanye nokubukeka okufana nosilika, le polymer entsha yabeka indinganiso entsha yomhlaba wonke yokuqina kwefayibha kanye namandla. Kwakungeyona nje ingqophamlando embonini yezindwangu; kwakuyintuthuko ebalulekile ekuthuthukisweni kwekhemistri ye-polymer.

Siqhubekela phambili namuhla, futhi i-Nylon-66 isalokhu iyinto ebalulekile ezimbonini ezisebenza kahle njengezindwangu, izimoto, izinto zikagesi, kanye nocingo nekhebula. Kodwa-ke, njengoba izidingo zokusebenza zanda, ukucubungula i-PA66 kuveza izithiyo zobuchwepheshe eziqhubekayo abakhiqizi ababhekana nazo nsuku zonke.

Ukucubungula “Amaphuzu Obuhlungu” e-PA66
Nakuba i-PA66 ithandwa kakhulu ngenxa yokuqina kwayo, isakhiwo sayo sama-molecule esingokwemvelo siholela ezinkingeni eziningana zokucubungula:

• Ukugeleza Okubi Kokuncibilika kanye Nokucindezela Okuphezulu Kokuncibilika: Ukuthamba okuphezulu kokuncibilika kwe-PA66 kunciphisa ukugeleza, okuholela ekusetshenzisweni kwamandla okwandisiwe, ukuguguleka kwemishini, kanye nesivinini sokukhiqiza esinqunyelwe.

• Iphupho Elibi “Le-Glass Fiber Floating”: Ukuze kutholakale amandla amakhulu esakhiwo, i-PA66 ivame ukuqiniswa nge-Glass Fiber (GF) engu-30%–50%. Ngenxa yokuthi amazinga okugeleza kwe-glass fiber kanye ne-nylon matrix awaguquguquki, i-fiber ivame ukuthuthela phezulu. Lokhu kuphumela ku-“Floating Fiber”—imicu emhlophe engathandeki, emaceleni ewonakalisa ukuphela kwendawo futhi idale amaphuzu okuhlushwa kokucindezeleka, okubeka engcupheni ubuqotho besakhiwo sengxenye.

• Amaphutha Okungaphezulu Nokulahlekelwa Ukucaca Kokubona: Ukucindezeleka okukhulu kokucubungula kungaholela “ekuqhekekeni koshaka” (ukuncibilika) noma ukwakheka kokufa, okubangela ukugoba kobuso futhi kuphazamise ukucaca kokubona kwama-polyamides asobala. Lokhu kuyinkinga ikakhulukazi ezinhlelweni zokusebenza lapho ikhwalithi yokubona ibaluleke kakhulu, njengasezimbozweni zezintambo eziphezulu kanye nekhebula.

Lezi zindawo ezibuhlungu zokucubungula azithinti nje kuphela ikhwalithi yomkhiqizo kodwa futhi ziholela emazingeni aphezulu okulahla izinto ezilahliwe, imijikelezo yokukhiqiza emide, kanye nezindleko zokusebenza ezikhuphukile—ekugcineni zithinta inzuzo yakho.

Njengophayona e-ukuguqulwa kwe-polymer okusekelwe ku-silicone,I-SILIKE inikeza zonke izinhlobo zezithasiselo ze-siloxane ezisebenza kahle kakhulu, ama-silicone masterbatches, izithasiselo ze-polymer, kanye nobuchwepheshe bokulungisa ubuso obuthuthukisa ukuqina, ukucutshungulwa, kanye nokuqina kwezinhlelo ze-Nylon-66, Polyamide 66 GF.

Izithasiselo ze-Silicone ze-SILIKE: Isixazululo Esisebenzayo Sokucubungula i-PA66
I-SILIKE inikeza iphothifoliyo yezixazululo ezikhethekile ezenzelwe ukuguqula ukucutshungulwa kwezinhlelo ze-polyamide:

1. I-SILIKE Silicone Masterbatch
Isetshenziswa kabanzi njengesithambisi sokucubungula esisebenzayo kanye nesithasiselo sokukhulula, i-SILIKEI-Silicone Masterbatch LYSI-307futhiI-Silixone Masterbatch LYSI-407zilungele izinhlelo ze-resin ezihambisana ne-PA6. Zithuthukisa izakhiwo zokucubungula kanye nekhwalithi yobuso ngokuhlinzeka:

• Ukugeleza kwe-resin okuthuthukisiwe kanye nokugcwaliswa/ukukhululwa kwesikhunta okulula.

• I-torque ye-extruder encishisiwe kanye ne-coefficient ephansi yokungqubuzana (i-COF).

• Ukumelana okukhulu nokuklwebheka.

Inzuzo Eyinhloko: Ukukhiqizwa okulungiselelwe kwemigqa ye-polyamide thermal break, okuvumela ukukhipha okusheshayo nokukhululwa kwesikhunta okungenamthungo.

2.I-SILIKE SILIMER 5150: Ukuqamba Okusha Kwe-Silicone Wax Eguquliwe

Isithasiselo sepulasitiki esisekelwe ku-silicone se-SILIKE i-SILIMER 5150 senzelwe ngqo ukubhekana nezinselele zokucubungula i-PA66 ezidinga kakhulu, ikakhulukazi kwizicelo eziqiniswe nge-fiber yengilazi nezibonakalayo:

• Iqeda “Ama-Floating Fibers”: Ngokuthuthukisa ukuhambisana kanye nokulinganisela kokugeleza phakathi kwama-resin kanye nama-glass fibers, i-Silicone lubricant-dispersing agent SILIMER 5150 iqinisekisa ukuthi ama-fiber ahlanganiswe ngokulinganayo, ivimbela ukufuduka aye phezulu. Lokhu kuphumela ekuqedeni okungenaphutha, okufanayo ngisho noma kulayishwa i-GF ephezulu.

• Ukushibilika Okuncibilikayo Okuthuthukisiwe: Isebenza njengesithambisi esinamandla sangaphakathi nangaphandle, i-Modified Silicone Wax yehlisa kakhulu ukuthambiseka kokuncibilika kanye nokucindezela kokukhipha. Lokhu kukhulisa ukusebenza kahle futhi kuvikela imishini yakho ekugugeni ngokweqile.

• Ikhwalithi Ephakeme Yomphezulu: Isithasiselo esisekelwe ku-silicone ye-SILIKE sinciphisa ubulukhuni bomphezulu futhi sivimbele ukwakheka kwe-die noma amaphutha "esikhumba soshaka", okuqinisekisa ukuqeda okukhazimulayo okuphezulu, okuphezulu okuhlangabezana nezindinganiso zobuhle eziqinile.

• Ukucaca Okubonakalayo Okugciniwe: Ngokungafani nama-wax endabuko,Izithasiselo ezisekelwe ku-silicone ye-SILIKE kanye nosizo lokukhiqiza i-SILIMER 5150gcina ukucaca kwe-PA66 ngisho nangaphansi kokucindezeleka okukhulu—okwenza kube ukukhetha okuhle kakhulu kwezembozo zentambo nezintambo ezicacile.

• Ukuqina Okuthuthukisiwe: Ngaphandle kokucutshungulwa, izithasiselo ze-Silicone ze-SILIKE zithuthukisa ukumelana nokuguguleka kwengxenye yokugcina, zandisa ubude bomkhiqizo futhi zinciphise izindleko zokugcinwa kwesikhathi eside.

Vula Amandla Aphelele e-PA66 nge-SILIKE

Imibuzo Evame Ukubuzwa: Ukuthuthukisa i-PA66 & Glass Fiber Reinforced Polyamide Processing
Q1: Ngingayisusa kanjani i-“Floating Fiber” (imicu emhlophe) ebusweni be-Glass Fiber eqinisiwe i-PA66?
A: “I-Floating Fiber” yenzeka lapho amazinga okugeleza kwe-nylon matrix kanye ne-glass fibers engaguquguquki. Ukusebenzisa i-SILIKE SILIMER 5150, isithasiselo se-silicone wax esiguquliwe, kuthuthukisa ukuhambisana kwe-interfacial kanye nebhalansi yokugeleza. Lokhu kuqinisekisa ukuthi i-PA66 resin ihlanganisa ngempumelelo imicu (30%–50% GF), okuholela ekuqedeni kobuso obubushelelezi, obufanayo ngaphandle kwemigqa ye-fiber ebonakalayo.

Umbuzo 2: Iyiphi indlela engcono kakhulu yokunciphisa ingcindezi yokukhipha izinto nokuthuthukisa ukugeleza kokuncibilika ekukhiqizweni kwe-PA66?
A: Ukuncibilika okuphezulu kwe-PA66 kuvame ukuholela ekucindezelweni okuphezulu kwe-extrusion kanye nokuguguleka kwemishini. I-SILIKE Silicone Masterbatch LYSI-407 kanye ne-SILIMER 5150 zisebenza njengezinto zokugcoba zangaphakathi nezangaphandle ezisebenza kahle kakhulu. Zinciphisa kakhulu ukuncibilika kokuncibilika kanye ne-torque ye-extruder, okuvumela amazinga okushisa aphansi okucubungula, ukusetshenziswa kwamandla okuncishisiwe, kanye nomkhiqizo ophumayo ophezulu.

Umbuzo 3: Ingabe izithasiselo zokucubungula zingathuthukisa ikhwalithi yobuso be-PA66 ngaphandle kokulahlekelwa ukucaca kokukhanya?
A: Yebo. Nakuba ama-wax endabuko angabangela ukufiphala noma “umswakama,” i-SILIKE SILIMER 5150 yenzelwe ngqo ama-polyamides abonakalayo. Inciphisa ukukhubazeka kobuso njenge-“sharkskin” kanye nokwakheka kokufa ngenkathi igcina ukucaca okubalulekile kokukhanya kanye nokucaca okudingekayo kwezembozo zentambo nekhebula eziphezulu kanye nezingxenye ze-PA66 ezisezingeni lokukhanya.
