Cov txheej txheem tseem ceeb ntawm kev tiv thaiv chassis suav nrog chassis sealing, chassis armor, tu thiab tu, thiab thawj lossis tom qab- ntau lawm galvanizing.
Chassis sealing yog ib qho tshuaj tiv thaiv xeb. Nws suav nrog kev txau cov nplaum nplaum heev, elastic heev, thiab corrosion heev - cov khoom siv roj hmab resistant rau lub tsheb chassis los tsim cov yeeb yaj kiab tiv thaiv. Nws daim ntawv thov yog qhov yooj yim thiab tsis tshua muaj nqi -, tab sis nws cov txiaj ntsig kev tiv thaiv kuj tseem txwv, nrog rau kev ua neej nyob feem ntau 2-3 xyoos. Chassis armor yog ib qho kev tiv thaiv zoo tshaj plaws. Nws siv cov ntaub ntawv tshwj xeeb polymer los tsim cov txheej txheej tuab, muaj zog tiv thaiv nrog cov adhesion muaj zog, hnav tsis kam, thiab corrosion kuj. Nws lub neej feem ntau tuaj yeem ncav cuag 5-10 xyoo, thiab nws kuj tseem muab lub suab nrov nrov thiab txo cov suab nrov.
Raws li cov ntaub ntawv siv, chassis armor tuaj yeem faib ua cov roj hmab -raws li, resin-raws li, thiab cov hom sib xyaw. Resin-raws li chassis armor yog roj-raws li, nrog rau siab hardness, zoo hnav tsis kam, ntev tiv thaiv lub sij hawm, thiab zoo heev waterproof, rustproof, thiab corrosion- pov thawj los, tab sis nws dries maj mam. Roj hmab-raws li chassis armor yog dej-raws li, muab cov rwb thaiv tsev zoo heev, suab rwb thaiv tsev, txo suab nrov, thiab kev poob siab. Nws muaj zog adhesion, zoo elasticity, thiab dries sai sai. Composite chassis armor sib txuas cov roj hmab thiab cov resin nrog rau lwm yam khoom, uas ua rau muaj zog adhesion, zoo toughness, thiab ntev dua - tiv thaiv lub chassis.
Ua ntej thov, lub tsheb yuav tsum tau nqa, thiab lub chassis huv si huv si ntawm av thiab roj siv lub siab - rab phom dej siab thiab tus neeg saib xyuas tshwj xeeb. Tom qab ntawd lub undercarriage yuav tsum tau qhuav nrog ib rab phom cua. Yog hais tias muaj xeb, nws yuav tsum tau polished rau lub ci xim hlau. Lub cav roj yias, kis vaj tse, tso pa tawm, nres kaw lus, sensors, thiab lwm qhov chaw uas tsis tas yuav tsum tau txheej yuav tsum nruj nreem npog. Daim ntawv thov ib puag ncig yuav tsum yog cov plua plav-dawb, zoo- qhov cua qhov chaw nrog qhov kub ntawm 15-30 degrees Celsius thiab av noo qis dua 60%.
Thaum lub sij hawm txau, yuav tsum tau siv rab phom tshwj xeeb, tswj qhov deb ntawm 15-30 cm ntawm lub chassis nto thiab txav mus tas li. Daim ntawv thov yuav tsum mus los ntawm sab hauv tawm thiab los ntawm sab saum toj mus rau hauv qab. Feem ntau, ntau lub tsho nyias nyias yog siv, 2-3 lub tsho tiv no, nrog rau lub sijhawm luv ntawm txhua lub tsho. Rau cov cheeb tsam uas cuam tshuam xws li chassis ntug, siv lub tsho tuab, ua kom tiav kev npog ntawm cov ces kaum thiab lwm yam ntsiab lus. Tag nrho cov thickness ntawm undercoating yog feem ntau ntawm 2-4 mm.
Tom qab txau, tso cai rau lub undercoating cua kom qhuav rau 24-48 teev, tsis txhob tsav tsheb los yog tiv tauj nrog dej thaum lub sijhawm no. Kev kho kom tiav feem ntau yuav siv sij hawm; tsav tsheb ntawm txoj kev du rau ob mus rau peb hnub tom qab daim ntawv thov los xyuas kom meej lub txheej ruaj khov. Kev tshuaj xyuas yog tsim nyog tom qab thov; kov tej qhov chaw uas ploj lawm los yog txheej txheej tsis sib xws.
