Cov tsheb tshiab lub zog yog ntsiag to dua li cov khoom siv hluav taws xob sab hauv lub tshuab hluav taws xob, thiab kev txhim kho ntawm lub zog tshiab tsheb kuj tseem ua rau cov kev cai nruj dua rau kev tswj cov suab nrov ntawm lub log tsheb. Cov log tsheb tshiab lub zog tuaj yeem hloov kho tau zoo dua rau cov kev xav tau ntawm cov xwm txheej tshiab los ntawm kev txhim kho cov qauv roj hmab, lub log tsheb sib piv, lub log ntim, cov khoom siv tread, tread pattern thiab lwm yam.
Laser tu tshuab raws li "ntsuab" txheej txheem tu, nyob rau hauv lub ntsiag to log tsheb manufacturing txheej txheem muaj ib tug zoo daim ntawv thov, siv tsom high-zog laser beams, irradiation ntawm organic polymer cov ntaub ntawv nto, kom cov nto ntawm cov khoom undergoes lub cev thiab tshuaj. hloov, thiaj li hloov nws cov khoom. tuaj yeem txhim kho qhov zoo ntawm cov log tsheb thiab cov txheej txheem tsim khoom, txhim khu kev sib raug zoo ntawm cov log tsheb thiab lub tsheb lub cev, txhim kho kev ua haujlwm ntawm lub tsheb tag nrho. Los ntawm txheej txheej sab hauv ntawm lub log tsheb nrog cov khoom muag muag gel polymer cov khoom sib xyaw, nws tuaj yeem paub txog kev ua haujlwm ntawm kev tawg, tiv thaiv kev tawg thiab tiv thaiv, thiab tib lub sijhawm, ib txheej ntawm polyurethane sponge yog pasted rau saum npoo. ntawm cov roj hmab los tiv thaiv, uas tuaj yeem paub qhov cuam tshuam ntawm acoustic thiab thermal rwb thaiv tsev, thiab nqus cov suab nrov ntawm cov kab noj hniav.
Laser tu tuaj yeem tshem tawm cov khoom seem seem ntawm cov phab ntsa sab hauv ntawm lub log, thiab txhim kho cov txheej txheem ntawm cov khoom sib xyaw thiab cov adhesion ntawm polyurethane daim txhuam cev. Cov txheej txheem ntxuav tsis siv cov khoom siv, tsis muaj kev puas tsuaj rau lub log tsheb, kev ua haujlwm siab, zoo sib xws, thiab tuaj yeem ua haujlwm tu.
Through the selection of pulsed laser equipment, sample parts are evaluated by developing a reasonable process flow. The surface tension values under different parameters were obtained by Dain Pen test. The results show that different process parameters (laser energy density, processing efficiency) will have an impact on the surface tension of the inner wall of the tire, for the production process of quiet tires should be reasonably formulated process parameters. Through the test, the laser cleaning is uniform and meets the substrate damage far to meet the requirements. After cleaning the inner surface friction coefficient increased >37mN / m, nto nro mus txog 40dyne / cm.
Siv lub roughness tester los kuaj qhov saum npoo tom qab kho laser, thaj tsam yog S1-S4, sib xws rau cov txheej txheem sib txawv, tus qauv xeem yog ISO1997, qhov nkhaus yog R, thiab lub lim yog GAUSS. Cov txiaj ntsig tau pom tias qhov sib txawv ntawm qhov sib txawv muaj qhov sib txawv ntawm qhov cuam tshuam ntawm qhov roughness ntawm qhov chaw, thiab qhov roughness nyob rau hauv S3 cheeb tsam yog qhov loj tshaj plaws, uas yog nyob rau hauv txoj kab nrog rau cov txiaj ntsig ntawm Dain Pen test, thiab kev kho laser zoo heev ua rau lub ntsej muag roughness. .
Kev soj ntsuam ntawm 1000x qhia ntau tus thoob ntiaj teb faib me me concave thaj ua rau thaj nrog micron-loj hais qhov twg lub laser irradiated, thaum lub laser ntaus nto ntawm cov khoom, nws rhuav tshem cov rubbery chain-zoo li qauv thiab ua rau qhov tsis xwm yeem concave feature kom nce lub nto roughness.
