Lamulo la 1/10 ndi njira yolunjika koma yovuta yopuma pantchito: pamene kuvala kwa abrasive kumachepetsa m'lifupi mwake ndi 1/10 kapena kuposerapo, gulaye iyenera kuchotsedwa ntchito. Lamuloli lafotokozedwa mu EN 1492-1 ndipo limazindikiridwa ndi ASME B30.9 ngati chizindikiro chachikulu cha kuvala mopitilira muyeso. Bukuli likufotokoza zomwe lamulo la 1/10 limatanthauza, momwe mungayezere kukula kwa ukonde molondola, chifukwa chake malirewo adasankhidwa, komanso momwe angagwiritsire ntchito pakuwunika kwa tsiku ndi tsiku. Kwa oyang'anira mbeta ndi akatswiri achitetezo, kumvetsetsa lamulo losavutali kungalepheretse kugwiritsa ntchito ma gulayeni owopsa.

Legeni yathyathyathya imachita zambiri osati kungonyamula katundu, koma imateteza. Malo otambalala, osalala amagawa kulemera kwa katundu pamalo okulirapo, kumachepetsa kwambiri kupanikizika pamalo aliwonse. Ili ndiye mfundo yofunikira yafizikiki kumbuyo kwa ma slings athyathyathya: Pressure = Force ÷ Area. Powonjezera malo olumikizirana, ma gulayeti athyathyathya amachepetsa chiwopsezo cha kuwonongeka kwa pamwamba, madontho, ndi kuphwanyidwa - kuzipangitsa kukhala chisankho chomwe chimakonda kukweza zida zolimba, zomalizidwa, kapena zowonongeka mosavuta. Bukhuli likufotokoza za fiziki ya kugawa kwamakasitomala, kufanizitsa ma gulayesi athyathyathya ndi njira zina zonyamulira, ndipo limapereka malangizo othandiza posankha m'lifupi mwake momwe mungagwiritsire ntchito gulaye.

Gola lathyathyathya lovotera matani 2 pokwera mowongoka limatha kunyamula tani imodzi yokhayo ikagwiritsidwa ntchito pamakona a 60°. Izi zili choncho chifukwa gulayeyo imakhudza kwambiri mwendo uliwonse wa gulayeyo—kang’ono kakang’ono pakati pa gulaye ndi yopingasa, m’pamenenso kumangikako kumakulirakulira. Malinga ndi EN 1492-1 ndi ASME B30.9, mphamvu iyenera kuchepetsedwa pamene gulaye imagwiritsidwa ntchito pa ngodya kapena masinthidwe amiyendo yambiri. Bukhuli likufotokoza za fiziki kumbuyo kwa ma angle factor, limapereka matebulo opangira ma slings osalala, komanso limapereka malangizo othandiza powerengera zolemetsa zogwira ntchito motetezeka pamachitidwe enieni adziko lapansi.

Choponyera chonyamulira chomwe chasungidwa chonyowa chingawoneke ngati chosawonongeka, koma chinyezi chingayambitse matenda a mildew, kuwonongeka kwa ulusi, ndipo-ngati gulaye ya nayiloni - kutaya mphamvu kwakanthawi mpaka 15% ikanyowa, mphamvu ikabwezeretsedwa ikaumitsa . Chofunikira kwambiri, gulaye za nayiloni zimatha kutaya mpaka 25% ya mphamvu zake zikanyowa chifukwa cha kuyamwa kwa chinyezi. Ma polyester slings, mosiyana, sakhudzidwa kwambiri ndi chinyezi koma amatha kudwala ndi mildew ndi kuvunda ngati atasungidwa monyowa. Bukhuli likuwunika zoopsa zomwe zimagwirizanitsidwa ndi gulayeni zonyowa, zowonongeka zenizeni za zipangizo zosiyanasiyana zopangira, ndi kufufuza ndi kuyanika kofunikira musanabweze gulaye chonyowa kuntchito.

Kudziwa nthawi yopuma pantchito yokweza gulaye ndi imodzi mwamaluso ofunikira kwambiri pakusungitsa chitetezo. Sling yomwe ikuwoneka yothandiza ikhoza kukhala ndi zowonongeka zobisika zomwe zimasokoneza mphamvu zake, pamene mitundu yowonongeka yowonekera-kudula, kuphulika, kutentha kwa mankhwala, kuwonongeka kwa kutentha, ndi kuwonongeka kwa UV-aliyense ali ndi ndondomeko yopuma pantchito yomwe imatanthauzidwa ndi ASME B30.9, OSHA, ndi EN 1492. Kwa oyang'anira kubera, akatswiri achitetezo, ndi ogwira ntchito, bukhuli limapereka chidziwitso chothandiza popanga zisankho zapanthawi yopuma pantchito.

Chovala chonyamulira chimatha kutaya mphamvu nthawi yayitali chisanawonekere - nthawi zambiri popanda chenjezo. Kutentha kwambiri, kuwala kwa ultraviolet (UV), ndi kukhudzana ndi mankhwala ndi zinthu zitatu zomwe zimakonda kwambiri zachilengedwe zomwe zimawononga ulusi wopangidwa. Malingana ndi Canadian Center for Occupational Health and Safety (CCOHS) , kuwala kwa dzuwa, chinyezi, ndi kutentha kwa pamwamba pa 90 ° C (194 ° F) kungathe kuwononga zonse za nayiloni ndi polyester. OSHA imanenanso kuti mphamvu za gulaye zimawonongeka chifukwa cha kuwala kwa dzuwa ndi kuwala kwa ultraviolet, ndipo imalimbikitsa kukaonana ndi wopanga kapena munthu woyenerera kuti apeze zofunika zina zopuma pantchito. Bukhuli likuwunika momwe chilengedwe chilichonse chimakhudzira kukhulupirika kwa gulaye, ndi zizindikiro zotani zomwe muyenera kuyang'ana, ndi momwe mungatetezere zonyamula zanu kuti zisawonongeke msanga.
