Amakuru

Polyamide (PA66), izwi kandi nka Nylon 66 cyangwa polyhexamethylene adipamide, ni pulasitiki y’ubuhanga ifite imikorere myiza, ikorwa binyuze mu gushonga kwa hexamethylenediamine na aside adipic. Ifite imiterere y’ingenzi ikurikira:

Ingufu nyinshi n'ubudahangarwa: PA66 ifite imbaraga nyinshi za mekanike, modulus yoroshye, kandi irakomeye ugereranije na PA6.

Ubudahangarwa Budasanzwe: Nk'imwe muri polyamides nziza zidashira, PA66 irakora neza mu bikorwa nk'ibice bya mekanike, vitesi, amaberiti, n'ibindi bice bidashira.

Ubudahangarwa Bwiza bw'Ubushyuhe: Ifite ubushyuhe bwa 250-260°C, PA66 ifite ubushyuhe bwinshi ugereranyije na PA6, bigatuma ikwiriye ahantu hashyuha cyane.

Irwanya cyane imiti: PA66 irwanya ingese ituruka ku mavuta, aside, alkali, n'ibindi bintu bitandukanye by'imiti.

Imiterere myiza yo kwisiga: Uretse kuba idapfa kwangirika, PA66 ifite ubushobozi bwo kwisiga, ikaba iya kabiri nyuma ya POM (Polyoxymethylene).

Ubudahangarwa Bwiza bwo Gucika kw'Imihangayiko no Kurwanya Ingaruka: PA66 ifite ubudahangarwa bwiza bwo kurwanya stress rupture kandi ifite imbaraga nziza zo guhangana n'ingaruka.

Ubudahangarwa bw'ibipimo: PA66 ifite ubushobozi bwo gufata amazi make ugereranije na PA6, nubwo ubushuhe bushobora kugira ingaruka ku kudahangarwa kwayo.

Uburyo bwinshi bwo gukoresha: PA66 ikoreshwa cyane mu bice bya mekanike bikikije moteri z'imodoka, ibikoresho by'ikoranabuhanga n'amashanyarazi, ibikoresho by'inganda, imyenda, n'ibindi.

Nubwo PA66 ifite ibyiza bitandukanye, ubushobozi bwayo bwo kudashira buracyashobora kunozwa kugira ngo ikoreshwe mu nganda zikenera cyane.

Iyi nkuru irasuzuma uburyo bwagaragaye bwo guhindura PA66 kandi ikanashyira ahagaragara SILIKE LYSI-704,inyongeramusaruro ikoreshwa mu gutunganya amavuta akozwe muri siliconeitanga ubushobozi bwo kudashira neza, kandi ikaba irambye ugereranije n'ibisubizo bya PTFE bisanzwe.

Ni ubuhe buryo bwihariye bwo guhindura ikoranabuhanga butuma PA66 idakomeza kwangirika mu nganda?

Uburyo gakondo bwo kunoza uburyo PA66 idashira mu nganda:

1. Kongeramo Fibres zo Gukomeza

Fibre y'ikirahure: Yongera imbaraga zo gukurura, gukomera, no kudashwanyagurika, bigatuma PA66 ikomera kandi iramba. Kongeramo fibre y'ikirahure hagati ya 15% na 50% byongera cyane kudashwanyagurika no kudashwanyagurika.

Fibre ya Carbone: Ituma ibintu bidashobora kwangirika, gukomera, kandi ikagabanya uburemere. Yongera kandi imbaraga zo kudashira no kwangirika kw'ibikoresho ku byuma bikora neza kandi bigakora neza.

2. Gukoresha ibikoresho by'ubutare

Uduce duto tw’amabuye y’agaciro: Utu duce duto dukomeza ubuso bwa PA66, bigabanya kwangirika mu bidukikije cyane. Nanone twongera ubushobozi bwo kudahinduka mu buryo bukabije binyuze mu kugabanya kwaguka k’ubushyuhe no kongera ubushyuhe bwo kunyura mu buryo bukabije, ibyo bigatuma umuntu amara igihe kirekire mu bihe bigoye.

3. Gushyiramo amavuta n'inyongeramusaruro bikomeye

Inyongeramusaruro: Inyongeramusaruro nka PTFE, MoS₂, cyangwaibikombe bya silikonikugabanya kwangirika no kwangirika ku buso bwa PA66, bigatuma imikorere yoroha kandi ikamara igihe kirekire, cyane cyane mu bice bya mekanike bigenda.

4. Guhindura ibinyabutabire (Kopolimeri)

Guhindura ibinyabutabire: Gushyiramo ibice bishya by’imiterere cyangwa copolymer bigabanya uburyohe bwo kwinjiza amazi, byongera ubukana, kandi bishobora kunoza ubukana bw’ubuso, bityo bikongera ubushobozi bwo kudasaza.

5. Ibihindura ingaruka n'ibihuza

Impinduka mu ngaruka: Kongeramo impinduka mu ngaruka (urugero, EPDM-G-MAH, POE-G-MAH) byongera gukomera no kuramba mu gihe cy'imbaraga za mekanike, ibyo bikaba bifasha mu buryo butaziguye kudashira kw'ingufu mu gukumira ivuka ry'imivuniko.

6. Uburyo bwiza bwo gutunganya no kumisha ifu

Kumisha no Gutunganya neza: PA66 ni hygroscopic, bityo kumisha neza (kuri 80–100°C mu gihe cy'amasaha 2-4) mbere yo gutunganya ni ingenzi cyane kugira ngo hirindwe inenge ziterwa n'ubushuhe zishobora kugira ingaruka mbi ku bushyuhe bwo kwangirika. Byongeye kandi, kubungabunga ubushyuhe bugenzurwa mu gihe cyo gutunganya (260–300°C) bituma ibikoresho bikomeza gukomera kandi bihamye.

7. Uburyo bwo kuvura ubuso

Amavuta yo gusiga ku buso n'amavuta yo gusiga ku buso: Gukoresha amavuta yo gusiga ku buso cyangwa amavuta yo gusiga ku buso, nk'amavuta yo gusiga ku bumba cyangwa icyuma, bishobora kugabanya cyane kwangirika no kwangirika. Ibi ni ingirakamaro cyane cyane ku bikoresho byihuta cyane cyangwa biremereye cyane aho hakenewe kugabanya kwangirika kurushaho kugira ngo igihe cyo gukoresha ibikoresho kirusheho kuba cyiza.

Umuti udasanzwe wa PTFE ku bikoresho bya Polyamide (PA66) bya Plastiki: SILIKE LYSI-704

Uretse uburyo busanzwe bwo guhindura ibintu,SILIKE LYSI-704—inyongeramusaruro ishingiye kuri silicone idashira—bigaragaza iterambere rikomeye mu kunoza kuramba no gukora neza kwa PA66.

Incamake y'ikoranabuhanga rya pulasitiki ryahinduwe

LYSI-704 ni inyongeramusaruro ishingiye kuri silicone yongera ubushobozi bwa PA66 bwo kudashira binyuze mu gukora urwego rwo kwisiga rudashira muri matrix ya polymer. Bitandukanye n'ibisubizo bisanzwe bidashobora kwangirika nka PTFE, LYSI-704 ikwirakwira neza muri nylon ku gipimo cyo kongeramo kiri hasi cyane.

LYSI-704 Ibisubizo by'ingenzi ku bikoresho bya pulasitiki by'ubwubatsi:

Ubudahangarwa bwo Kwambara: LYSI-704 itanga ubudahangarwa bwo Kwambara nk'ibisubizo bishingiye kuri PTFE ariko ku giciro gito ku bidukikije, kuko nta fluorine irimo, bikemura impungenge zikomeje kwiyongera ku birebana na PFAS (ibintu bya per- na polyfluoroalkyl).

Imbaraga z’Ingaruka Zinoze: Uretse kongera imbaraga zo kudashira, LYSI-704 inanoza imbaraga zo guhagarara, mbere byari bigoye kugeraho icyarimwe iyo ubudashira buri hejuru.

Kunoza Imiterere y'Ubwiza: Iyo ishyizwe muri PA66 hamwe n'imigozi y'ikirahure, LYSI-704 ikemura ikibazo cy'uko imigozi ireremba, ikongera ubwiza bw'ubuso kandi ikabukoresha neza aho imiterere ari ingenzi.

Kuramba: Iri koranabuhanga rishingiye kuri silikoni ritanga ubundi buryo burambye bwo gusimbura PTFE, rigabanya ikoreshwa ry'umutungo n'ibisigazwa bya karuboni mu gihe ritanga umusaruro mwiza.

Ibisubizo by'igerageza

Ibisabwa mu isuzuma ryo kudashira: gukoresha ibiro 10, gukoresha ibiro 40 by'umuvuduko ku gipimo, n'igihe cy'amasaha 3.

Mu bikoresho bya PA66, igipimo cyo gushwanyagurika kw'icyitegererezo kirimo ubusa ni 0.143, kandi igihombo cy'uburemere giterwa no kwangirika kingana na 1084mg. Nubwo igipimo cyo gushwanyagurika n'uburemere bw'icyitegererezo hamwe na PTFE byongeweho byagabanutse cyane, ntibishobora guhura na LYSI - 704.

Iyo hongeweho 5% LYSI – 704, igipimo cyo gukururana ni 0.103 naho uburemere bwacyo ni 93mg.

Kuki silicone masterbatch LYSI-704 ikoresha PTFE?

• Ubudahangarwa bungana cyangwa bwiza kurushaho

• Nta mpungenge za PFAS

• Igipimo cyo kongeramo kiri hasi kirakenewe

• Inyungu zongeweho zo kurangiza ubuso

Porogaramu nziza:

Inyongeramusaruro ya LYSI-704 ifasha cyane cyane mu nganda zisaba imikorere myiza no kuramba, nko mu modoka, mu by'ikoranabuhanga, no mu nganda. Ni nziza cyane ku bikoresho nk'ibikoresho, amapine, n'ibikoresho bya mekanike bishobora kwangirika cyane.

Umwanzuro: Ongera ibice byawe bya nylon ukoresheje SILIKE Wear-Resistant Agent LYSI-704

Niba ushaka ibisubizo byo kongera ubushobozi bwo kwangirika kw'ibice byawe bya nylon 66 cyangwa izindi plastiki z'ubuhanga,Amavuta ya SILIKE LYSI-704 atanga ubundi buryo burambye kandi budasanzwe bwo gusimbura inyongeramusaruro gakondo nka PTFE Lubricants na Additives. Mu kunoza ubushobozi bwo kwangirika, imbaraga z'ingaruka, n'ubwiza bw'ubuso, iyi nyongeramusaruro ishingiye kuri silicone ni ingenzi mu gufungura ubushobozi bwose bwa PA66 mu nganda.

Kugira ngo umenye byinshi ku buryo inyongeramusaruro ya silicone LYSI-704 ishobora kunoza ibice byawe bya PA66, hamagara SILIKE Technology uyu munsi. Dutanga inama zihariye, ingero z'ubuntu, n'ubufasha burambuye bwa tekiniki kugira ngo bigufashe gufata ibyemezo byiza by'ibikoresho by'ikoranabuhanga bihindura ibyo ukeneye.
