Uma isampula efanayo ibonisa umehluko wezinombolo ezimbili ekulahlekelweni kokuhuzuka phakathi kwamalebhu amabili, izinto ezisetshenziswayo - hhayi umshini - ngokuvamile ziyimbangela.
Izindlela zokuhlola ukugugulekakungakanani okulahlekile ngaphansi komthwalo ochaziwe kanye nendlela. Umthwalo, ubukhali obuhlabayo kanye nesimo sokuxhumana yizinto ezintathu ezilawulayo, kanti izinto ezisetshenziswayo zithwala zonke ezintathu.
1. Imininingwane ngokushesha
| Indlela | Izinto Ezisetshenziswayo Eziyinhloko kanye Namapharamitha |
|---|---|
| I-MartindaleI-ISO 12947 | I-Wool abradant + felt (≥ 140 mm); isisindo esiphelele(595 ± 7) g → 9 kPa, (795 ± 7) g → 12 kPa; izindwangu ezimboziwe (198 ± 2) g → 3 kPa nephepha elingangeni manzi elingu-600# |
| I-TaberI-ASTM D3884 | Amasondo e-Calibrase CS-10/CS-17, i-Calibrade H-18/H-22; umthwalo wengalo 250 g, isisindo siyanikezwa500/1000 g; imicu i-S-33 (360 FEPA), S-42 (180 ANSI-CAMI) |
| I-DINI-ISO 4649 | I-aluminium oxidei-grit 60ishidi, ~474 × 402 mm; amandla aqondile10 N; 40 m ukuwela |
| I-CrockmeterI-AATCC 8 / ISO 105-X12 | Indwangu yekotini ejwayelekile; umunwe(16 ± 0.1) mmububanzi, ibhlogo elingu-19 × 25.4 mm lenqwaba; amandla(9 ± 0.2) Nithrekhi (104 ± 3) mm |
Amabanga awakwazi ukushintshaniswa: I-CS-10 ilingisa ukuguga okuncane, ukusika kwe-H-18 kunzima kakhulu — imiphumela ingahluka kaningana.
2. Ukushintsha Nokulungisa Isakhiwo
| Okusebenzisekayo | Isilinganiso |
|---|---|
| I-Martindale abradant & felt | Kuvuselelwa ngaphambi kokuhlolwa ngakunye; njalo ngama-rub angu-50,000 ekugijimeni isikhathi eside |
| Imichilo yesandpaper ye-taber | Njaloimijikelezo engu-200–500 |
| Amasondo e-taber | Ukuthatha umhlalaphansi e-44.4 mm (1.75 in)ububanzi — phansi kuze kufike kulebula. Amasondo e-Calibrase ayaphelelwa yisikhathi |
| Ukulungiswa kabusha kwe-taber | Amasondo amasha angu-2 × 50 imijikelezo; 25 noma 50 ngaphambi kokuhlolwa.Idiski ye-S-11 isetshenziswa kanye kuphela |
| Ishidi lokukhuhla le-DIN | Kungasetshenziswa ngenkathi ukulahleka kwereferensi kuhlala kungakapheli180–220 mg; ngaphezu kuka-220 mg kubukhali kakhulu, ngaphansi kuka-180 mg kubuthakathaka kakhulu |
⚠️
Ukwehluleka okuyingozi kakhulu.Umbhalo osetshenziswe ngokweqile noma ofundeka kabiokuphansi ngamanga, ngakho-ke umkhiqizo ongahambisani nawo uyadlula.
3. Susa · Qondanisa · Vikela
- Ungalokothi uthinteubuso besondo noma bomunwe ngezandla ezingenalutho; ungalokothi ugobe ishidi le-DIN.
- Gcina ikhanda ligxile ku-turntable (ngokuvamile ≤0.05 mmukungavamile); faka imichilo eyisicaba.
- Qinisa ngokuvundlile ngezigaba; gijima ungalayishiwe ukuze uqinisekise ukuthi akukho msindo noma ukuxega.
A okumise okwe-crescentuphawu esikhundleni sendandatho efanayo lusho ukungavamile noma ubuso besondo obungalingani.
4. Linganisa Kabusha Ngemva Kwanoma Yiluphi Ushintsho
- I-Martindale— qinisekisa u-595 g / 795 g we-9 kPa / 12 kPa
- I-Taber— amasondo amasha aphukile 2 × 50; qinisekisa 250/500/1,000 g; susa udoti
- I-DIN— hlola kabusha nge-reference compound cishe njalo ngemva kokuhlolwa okungu-10; hlola kabusha uma ukusabalala kudlula u-15 mg
- I-Crockmeter— qinisekisa ubude bethrekhi obungu-9 N; isimo ngokwe-ISO 139
5. Izinto Ezibalulekile Zokugcina Isitoreji
Kulawulwa izinga lokushisa kanye nomswakama (kuyadingeka emigqeni ye-S-42); isicaba, engathululwanga, engagobile; i-conditioner yoboya kanye nendwangu kakotini ngokwe-ISO 139; vala bese ubhala usuku lokusala.
Kumugqa owodwa:hhayi ngokushintsha kaningi —indlela efanele, izikhawu ezilotshiwe, ukufakwa okuqondiswe kahle, ukulinganisa kabusha ngemva kokushintsha, isitoreji esilawulwayo.
