Yuav ua li cas qhia yog tias Nylon tais diav yog ua los ntawm high - cov neeg tiv thaiv nylon
High - Koj hnav - Cov khoom lag luam uas tau cuam tshuam nrog cov ntaub ntawv me me (xws li cov ntsiab lus ntxiv) Koj tuaj yeem txheeb xyuas nws kom raug raws li plaub -}}}}}}}}}}}}} Cov txheej txheem, thiab tshuaj xyuas cov khoom kom tsis txhob muaj kev ntxhov siab nrog cov nylon dog dig. Cov kauj ruam tshwj xeeb yog raws li hauv qab no:

1. Khij daim ntawv lo: Txheeb xyuas cov ntaub ntawv cov ntaub ntawv ua ntej.

Qhabnias siab - Koj hnav- Cov ntsiab lus hloov kho nylon cov lus qhia, uas yog qhov ncaj tshaj plaws los txheeb xyuas lawv:

Txheeb xyuas cov khoom cim thiab cov lus qhia: high - fiber ntau, "lossis" nylon + molybdenum disgfuled "). Ib txhia tseem yuav qhia cov hnav -} Cov kab ntsig ntsig ntsig txog (piv txwv li, rockwell hardness thiab coeffelient ntawm kev sib txhuam). Yog tias nws tsuas yog sau npe "dog dig nylon," lossis "pa66" tsis muaj ib yam dab tsi uas tsis muaj ib qho kev hloov pauv, nws tsis yog hnav}} Cov khoom siv tau hloov tshiab.
Paub meej tias cov ntawv tshaj tawm hom thiab xeem: Thaum xaiv cov npe nrov nrov (xws li cov ntawv ceeb toom tsom xam (xws li kev ntsuas tsom xam tawm los ntawm kev ua haujlwm thib peb). Daim ntawv tshaj tawm no yuav qhia meej seb puas tau hloov kho cov khoom xyaw xws li khob fiber ntau thiab cov feem pua ​​(piv txwv li cov iav fiber ntau ntxiv Cov Chaw Ua Kasers tsis muaj npe lag luam thiab daim ntawv ceeb toom tsis tuaj yeem lav tau kom muaj cov khoom siv resistant zoo.

2. Tsos: Paub cov khoom siv los ntawm cov ntsiab lus saum npoo
High - Koj hnav- Cov khoom siv tsis txaus ntseeg los ntawm cov nylon zoo nkauj vim nws muaj pes tsawg leeg:

Xim thiab cilified nylon log nrog ntxiv cov iav fiber ntau yog cov fiber ntau (iav fiber ntau ntxiv) thiab cov xim muaj zog thiab dawb ntawm streaking. Zoo dog dig nylon log yog feem ntau ci dawb los yog beige, nrog qhov zoo dua. Hloov nylon log muaj graphite lossis molybdenum disulfide nyiam ua xim dub lossis xim zoo nkauj) thiab yuav muaj cov xim hlau dub lossis xim zoo nkauj ntawm cov hloov kho. Nto ntom ntom thiab tsis xws luag: Vim yog cov khoom siv raw thiab hnav tsis yooj yim, impurities, lossis honeycomb {}}} heev} zoo li qhov kov. Zoo dog dig nylon log nrog kev ua ntxhib yog nquag mus rau saum densions thiab flash, hnav ceev ceev vim tias tsis muaj zog dhau sijhawm.

3. Kev ntsuas kev ntsuas: Piv sib txawv ntawm cov haujlwm yooj yim
Siv cov cuab yeej siv, koj tuaj yeem pib ntsuas cov coj tsis kam ntawm cov khoom tiv thaiv cov khoom kom paub qhov txawv ntawm kev hloov kho thiab zoo nkauj heev nylon:

Kuaj Hardness: Siv pob zeb hluav taws xob: lossis cov cuab yeej nyuaj xws li tus yuam sij lossis riam phom) sim lub log nto hardness. Heev hnav - Tsis txhob muaj cov roj ntsha nylon (xws li 30% fiber ntau) feem ntau muaj lub pob zeb hardness ntawm ntau dua 100 hrr. Rubbing nrog ib tug tseem ceeb nplooj tsuas yog ntiav cov cim thiab tsis yog tus chipping. Feem ntau cov nylon feem ntau muaj lub hardness ntawm 80 {- 90 hrr, uas ua rau tob dua khawb thiab txawm tias muaj yas tawg. Kev sib piv hnyav: Rau cov casters ntawm tib cov kev qhia tshwj xeeb (tib lub zog loj dua li ntawm cov iav nylon hnyav dua 15%} {} {} 1.14G / cm³). Piv txwv li, ib qho caster nrog ib lub cheeb ntawm 100 hli thiab dav ntawm 20mm yuav hnyav kwv yees li 150g rau ib lub iav fiber-hloov kho lub log yuav hnyav li 180-200g. Qhov no tuaj yeem txiav txim sai li sai tau los ntawm kev hnyav.

4. Qhia txog cov yam ntxwv: Siv cov khoom tshwj xeeb ntawm cov ntaub ntawv hloov kho
Heev hnav - Tsis pom cov khoom lag luam Nylon tsis pom muaj qee txoj hauv kev:

Combusionion kev xeem (txuas ntxiv mus ceev faj, kuaj me me pom zoo): Siv me me ntawm cov cav log me me thiab hlawv nws. Zoo hnav - tiv taus cov ntaub nkig zoo nkauj nrog cov pa hluav taws me me, tawm tom qab dub, thiab resistant iav fiber residue. Cov nylon dog dig nrog cov nplaim hluavtaws daj thiab cov pa luam yeeb ntau, tawm hauv qab qhov tawm {} dawb, thiab yooj yim tsoo cov seem.

Siab - kub sim: nthuav tawm lub tawb rau 80 - 100℃(piv txwv li lub tshav kub kub ntawm qhov chaw qis) rau ib teev. Zoo heev hnav-resistant hloov lylon (piv txwv li, cov fiber ntau hloov kho) cov khoom ua yeeb yam tsis muaj kev muag khoom lossis deformation thaum tshem tawm cov cua sov txhim kho. Zoo dog dig nylon cov khoom pov thawj tsis zoo lub tshav kub ua kom tsis taus, nquag mus rau saum npoo nplaum thiab me ntsis log vau. Qhov no tsis ncaj qha qhia txog cov qauv kev ruaj ntseg ntawm cov khoom hloov kho, cuam tshuam tsis tawm tsam cov khoom tiv thaiv.
