Umurage n'ibibazo bya Nylon-66

Ku ya 28 Gashyantare 1935, habayeho iterambere rikomeye mu bumenyi bw'ibikoresho ubwo umuhanga mu bya siyansi w'Umunyamerika Wallace Hume Carothers yatsindaga neza Nylon-66, polyamide ifite imiterere itangaje. Kubera ko ifite ubushyuhe bwinshi bwo gushonga bwa 263°C, irwanya cyane ibintu bisanzwe, kandi isa n'iy'ubudodo, iyi polymer nshya yashyizeho urugero rushya ku isi rwo kuramba no gukomera kwa fibre. Ntabwo yari intambwe ikomeye ku nganda z'imyenda gusa; yari intambwe ikomeye mu iterambere rya chimie ya polymer.

Dukomeje kwihuta kugeza uyu munsi, kandi Nylon-66 iracyari ingenzi mu nganda zikora neza cyane nk'imyenda, imodoka, ibikoresho by'ikoranabuhanga, insinga n'insinga. Ariko, uko ibisabwa mu mikorere byiyongera, gutunganya PA66 bikomeza guteza imbere imbogamizi za tekiniki abakora bahura nazo buri munsi.

Uburyo bwo gutunganya "Ingingo z'ububabare" bwa PA66
Nubwo PA66 ikundwa kubera gukomera kwayo, imiterere yayo ya molekile itera imbogamizi nyinshi mu kuyitunganya:

• Gushonga nabi no gusohora umwuka mwinshi: Ubushyuhe bwinshi bwa PA66 melt bugabanya amazi, bigatuma ingufu zikoreshwa, ibikoresho bishira, ndetse n'umuvuduko mu gukora ukagabanuka.

• Inzozi mbi za "Fibre y'Ikirahure Irekura": Kugira ngo igere ku mbaraga zidasanzwe z'imiterere, PA66 ikunze gukomezwa na Fibre y'Ikirahure ya 30%–50%. Kubera ko umuvuduko w'amazi y'ikirahure na matrix ya nylon udahuye, fibre akenshi zijya ku buso. Ibi bivamo "Fibre y'Ikirahure" - imirongo yera idashimishije, igoramye yangiza imiterere y'ubuso kandi igatera ahantu hakomeye ho guhangayika, bikabangamira imiterere y'igice.

• Ubusembwa bwo hejuru no gutakaza ubushobozi bwo kubona neza: Uburemere bwinshi bwo gutunganya ibintu bushobora gutera "gushwanyagurika kw'uruhu rw'inyama" (gushonga) cyangwa kwiremamo uduce duto, bigatera ubukana bw'ubuso no kugoreka uburyo bwo kubona neza bwa polyamides zibonerana. Ibi ni ikibazo cyane cyane ku mikoreshereze aho ubwiza bw'ishusho ari ingenzi cyane, nko mu nsinga nini n'insinga.

Izi ngingo zibangamira gutunganya ibicuruzwa ntizigira ingaruka gusa ku bwiza bw'ibicuruzwa ahubwo zinatuma habaho ubwiyongere bw'ibisigazwa by'ibicuruzwa, imikorere igakomeza igihe kirekire, ndetse n'ibiciro by'ibikorwa byiyongera—amaherezo bigira ingaruka ku nyungu zawe.

Nk'umuntu wabaye umupayiniya muriguhindura polimeri ishingiye kuri silikoni,SILIKE itanga ubwoko bwose bw'inyongera za siloxane zikora neza, silicone masterbatches, inyongera za polymer, n'ikoranabuhanga ryo kunoza ubuso rituma sisitemu za Nylon-66, Polyamide 66 GF ziramba, zigatunganywa neza, kandi zigakomera.

Inyongera za Silicone za SILIKE: Igisubizo cyiza cyo gutunganya PA66
SILIKE itanga urutonde rw'ibisubizo byihariye byagenewe guhindura uburyo bwo gutunganya sisitemu za polyamide:

1. SILIKE Silicone Masterbatch
Ikoreshwa cyane nk'amavuta yo gutunganya neza no gusohora amavuta, SILIKESilicone Masterbatch LYSI-307naSilixone Masterbatch LYSI-407ni nziza cyane kuri sisitemu za resin zijyanye na PA6. Binoza imiterere yo gutunganya no kunoza ubuziranenge bw'ubuso binyuze mu gutanga:

• Kongera ubushobozi bwo gutembera neza kw'ibumba no koroshya kuzuza/kurekura ibishishwa.

• Kugabanuka kwa torque ya extruder hamwe n'umuvuduko muke w'ingufu (COF).

• Ubudahangarwa bukomeye bwo kwangirika no gushwanyagurika.

Akamaro k'ingenzi: Gukora neza utubuto twa polyamide thermal break strips, bigatuma umusaruro wihuta kandi imyumbati ikavunguka neza.

2.SILIKE SILIMER 5150: Udushya twa Silicone Wax twahinduwe

Inyongeramusaruro ya plastiki ikozwe muri silikoni ya SILIKE SILIMER 5150 yakozwe by'umwihariko kugira ngo ikemure ibibazo bikomeye byo gutunganya PA66, cyane cyane ku bijyanye no kongera imbaraga mu byuma bikoresha ikirahure kandi bibonerana:

• Ikuraho "Floating Fibers": Mu kunoza uburinganire n'uburyo amazi anyura hagati y'imigozi ya resin n'ikirahure, Silicone lubricant-dispersing agent SILIMER 5150 ikora ku buryo imigozi ifatanye neza, ikarinda kwimuka ku buso. Ibi bituma imigozi irangira neza ndetse no mu gihe hari GF nyinshi.

• Gushonga neza: Ikora nk'amavuta akomeye imbere no hanze, Modified Silicone Wax igabanya cyane ubushyuhe n'umuvuduko wo gushonga. Ibi byongera imikorere myiza kandi bikarinda ibikoresho byawe kwangirika cyane.

• Ubwiza bw'Ubuso Buhebuje: Inyongeramusaruro ishingiye kuri silike igabanya ubukana bw'ubuso kandi ikarinda ko hagira ikibazo cyo kwirema cyangwa "ubusembwa bw'ingufu", bigatuma irabagirana cyane kandi igezweho kandi yujuje ibisabwa ku bwiza.

• Umucyo w'amatara wabugenewe: Bitandukanye n'isuka gakondo,Inyongeramusaruro zishingiye kuri silike n'ubufasha mu gukora SILIMER 5150Gukomeza gukorera mu mucyo wa PA66 nubwo haba hari imbaraga nyinshi—bigatuma iba amahitamo meza yo gukoresha insinga zisobanutse neza n'insinga.

• Kuramba Kwagutse: Uretse gutunganya, SILIKE's Silicone Additives yongera ubushobozi bwo kudashwanyagurika kw'igice cya nyuma, yongera igihe kirekire cy'umusaruro kandi ikagabanya ikiguzi cyo kubungabunga igihe kirekire.

Fungura ubushobozi bwose bwa PA66 ukoresheje SILIKE
Ese witeguye kunoza uburyo bwo gutunganya PA66 yawe no gutsinda imbogamizi zibangamira umusaruro wawe? SILIKE ni umufatanyabikorwa washakaga. Ukoresheje siloxane yongerewemo SILIMER 5150 ifite ubushobozi bwo gukora neza hamwe na silicone masterbatches zacu, ushobora koroshya uburyo bwo gukora, kongera ireme ry'ibicuruzwa, no kongera inyungu zawe.

Vugana na SILIKE uyu munsi kugira ngo umenye uburyo twazamura amahame ngenderwaho y’inganda za PA 66, cyangwaGuhindura PA66 GF n'ibisubizo by'inyongeramusaruro bishingiye kuri silicone.

Ibibazo Bikunze Kubazwa: Gutunganya neza PA66 na Fibre y'Ikirahure ikoresheje Polyamide
Q1: Nakuraho nte "Floating Fiber" (imirongo yera) ku buso bwa Glass Fiber reinforced PA66?
A: "Floating Fiber" ibaho iyo umuvuduko w'amazi ya nylon matrix n'imigozi y'ibirahure udahuye. Hakoreshejwe SILIKE SILIMER 5150, inyongeramusaruro ya silicone wax yahinduwe, yongera imikoranire myiza hagati y'urusobe rw'amazi n'uburyo amazi agenda. Ibi bituma resin ya PA66 ifunga neza imigozi (30%–50% GF), bigatuma ubuso bugaragara neza kandi butagira imirongo igaragara ya fibre.

Q2: Ni ubuhe buryo bwiza bwo kugabanya umuvuduko wo gusohora no kunoza urujya n'uruza rw'amazi ashongeshejwe mu musaruro wa PA66?
A: Ubushyuhe bwinshi bwo gushonga muri PA66 bukunze gutuma habaho umuvuduko mwinshi wo gusohora no kwangirika kw'ibikoresho. SILIKE Silicone Masterbatch LYSI-407 na SILIMER 5150 bikora nk'amavuta yo kwisiga imbere no hanze akora neza cyane. Bigabanya cyane ubushyuhe bwo gushonga no gusohora, bigatuma ubushyuhe bwo gutunganya ibintu bugabanuka, ingufu zikoreshwa kugabanuka, kandi umusaruro urushaho kwiyongera.

Q3: Ese inyongeramusaruro zishobora kongera ubwiza bw'ubuso bwa PA66 hatabayeho gutakaza ubwiza bw'urumuri?
A: Yego. Nubwo ishashi gakondo ishobora gutera ubushyuhe cyangwa "ibihu," SILIKE SILIMER 5150 yagenewe by'umwihariko polyamides zibonerana. Igabanya inenge zo hejuru nk'"ingufu z'inyama" n'ubwinshi bw'ingufu mu gihe ikomeza kugira ubwiza bw'ingenzi bw'urumuri n'ubuziranenge bukenewe ku nsinga nini n'insinga ndetse n'ibice bya PA66 by'urwego rw'ubuziranenge.
