Dab tsi ib puag ncig tsis haum rau nylon casters?

Ib puag ncig ib puag ncig qhov twg nylon casters tsis haum
Txawm hais tias Nylon caslon casters tau siv dav siv, vim lawv cov khoom siv tsis zoo, thiab tsis muaj peev xwm ua tau zoo, tsis muaj kev nyab xeeb rau kev phom sij hauv qab no. Ua ntej txhawb tshem tawm lossis hloov cov casters nrog lwm cov khoom siv:

1. Muaj tsawg heev {{{{-}}}}} {}}}} kub-resistant hloov nylon hauv qab -40 degree).
Cov xwm txheej raug: Sub - Pes Tsawg Lub Caij Ntuj No (}}
Vim li cas tsis sib haum: Nylon cov qauv molecular yuav ploj mus ntawm huab huab ntawm huab huab, ua qhov nyuaj thiab nkig. Txawm tias me me tshee (xws li pob tw nyob rau hauv lub laub lossis cuam tshuam los ntawm muab cov khoom thauj) tuaj yeem ua rau cov kab nrib pleb, thiab lawv muaj peev xwm tawg. Cov roj hauv cov bearings tuaj yeem khov, ua rau muaj teeb meem thiab zawv plab. Lub log muaj peev xwm tawg, muaj feem cuam tshuam cov khoom thauj mus rau saum toj dua vim yog log fragmentation.

2. Ntev-}} {2} {{{5} {} {} {} {} {} {} {} {
Cov xwm txheej raug suav nrog cov kev cob qhia siab (xws li outre kev cob qhia thiab 130℃cov cua sov kho kom sov (thaj av kub tshaj 60℃thiab pab tau ntev dua).

Vim li cas tsis sib xws: qhov kub ua rau nws cov khoom siv dag zog (piv txwv li cov xeeb ntxwv yl {{{5%} 60% los 80 degree). Kev siv ntev ntev tuaj yeem ua rau deformation, xws li feathening ntawm lub log tsuj thiab txo qis hauv lub cheeb, thiab muaj adhesion ntawm lub log mus rau tus ncej. Yog tias thauj khoom, lub log muag muag yuav tsis muaj peev xwm txhawb qhov hnyav, ua rau cov khoom siv sib tsoo thiab cov khoom siv lossis khoom thauj khoom.

3. Cov neeg muaj ib puag ncig uas muaj huab cua hlob (sib chwv nrog cov accours, hauv paus, thiab cov kuab tshuaj muaj zog)
Cov ntawv thov raug: Tshuaj Tiv Thaiv Tshuaj (piv txwv li, thaj chaw rau kev hloov cov sulfuric acid lossis sodium hydroxide daws teeb meem saum 30%, thiab thaj chaw ib puag ncig hydrochloric acid tso tsheb hlau luam); Kuaj cov chaw nrog cov chaw muaj mob corrosive heev (piv txwv li, cov laub khaws cia xws li nitric acid thiab acetone); thiab electroplating kev cob qhia (piv txwv li, thaj chaw rau kev kho kom muaj dej khib nyiab uas muaj chromic acid thiab cyanide).
Vim li cas tsis sib xws: dog dig BLON tsuas yog tiv taus cov kua qaub tsis muaj zog thiab cov hauv paus. Thaum nthuav tawm cov tshuaj uas xeb zoo, nws cov kab molecular muaj kev cuam tshuam, ua rau "o- kev ua rau" cov tshuaj tiv thaiv. Lub log nto yuav nrawm dua ua cov nplaum thiab nthuav dav hauv ntim, muaj peev xwm ua rau log fragmentation nyob rau hauv 248 teev. Txawm hais tias chlon tsis tuaj yeem tiv taus lub sijhawm ntev ntawm cov accesrated ntawm cov acids thiab cov hauv paus, thaum kawg ua rau kev ua tsis tiav. Cov khoom siv tsis tuaj yeem ua rau ib puag ncig lossis khoom thauj.

4. Cov ntxhib ntxig / siab heev {{- kev cuam tshuam ib puag ncig (muaj kev tiv thaiv av yooj yim, yooj yim kom tau daig los ntawm impurities)
Cov ntawv thov raug: Cov chaw tsim khoom (unfineled gravel av, unfinished rebar), thiab cov chaw lim dej (cov ntaub ntawv pov tseg nrog cov ntawv pov thawj hlau thiab vuam slag).
Vim li cas tsis sib xws: Nylon log muaj lub siab tawv tawv tab sis tsis muaj zog elasticity. Thaum lawv nkag mus rau hauv qhov chaw tiv thaiv kev tiv thaiv (xws li cov pob zeb uas muaj zog tshaj plaws) ntawm cov kev ntxhov siab, "ua rau muaj kev ntxhov siab rau 3-5 zaus nrawm dua ntawm qhov chaw tiaj. Tsis muaj lub log uas tsis sib haum tuaj yeem tsim kho tsis pub dhau 1-2 lub lis piam. Tsis tas li ntawd, kev tsis txaus siab (cov ntawv pov tseg hlau thiab cov kab mob vuam uas tau yooj yim dua thiab cov log tsheb tawm tsam thiab lub log tsheb tawm tsam thiab cov txiaj ntsig ntawm kev puas tsuaj rau kev puas tsuaj dua.

5. Ultra - high - zaus}}}}}}}}}} pa yuavents
Cov xwm txheej raug: Kev siv lub laub (xws li cov khoom siv thauj khoom thiab cov khoom siv hluav taws xob (xws li cov khoom siv hluav taws xob (xws li cov chaw nyob deb nroog thiab cov khoom siv hluav taws xob hauv qab).
Vim li cas tsis sib xws: Nylon modulus yog qhov qis dua li ntawm roj hmab thiab roj hmab kwv yees li 2.8 GPA), ua rau muaj kev nqus tau zoo heev 0.00 Nyob rau hauv high - zaus} zaus kev co av deetrations, ua rau tsis yog nrov nrov dua li roj hmab log) tab sis kuj kis tau vibrations rau cov khoom thauj. Qhov no tuaj yeem ua rau kev puas tsuaj sab hauv cov twj paj nruag thiab tsim kev pheej hmoo ntawm tawg rau cov khoom tsis yooj yim (xws li iav thiab ceramics).
