Chokongoletsera chakunja chakutsogolo.
Mbale yokongoletsera yakunja yakutsogolo ndi mbale yokongoletsera yakunja yomwe ili pansi pa chitseko cha galimoto. Imalumikizidwa ndi chitsulo chomangira kudzera mu zomangira. Mphepete mwa mbale yokongoletsera yakunja imalumikizidwa ndi chitsulo chomangira ndipo imatetezedwa ndi chomangira cha mbali ziwiri. Gawoli lili kunja kwa chitseko, makamaka limagwira ntchito yokongoletsa komanso yoteteza, komanso gawo la mawonekedwe a galimoto, zomwe zimakhudza kapangidwe kakunja ndi kalembedwe ka galimotoyo. Kuphatikiza apo, gulu lokongoletsa zitseko (kuphatikiza gulu lokongoletsa zitseko zakutsogolo) limagwira ntchito yofunika kwambiri pakupanga magalimoto, sikuti amangogwira ntchito yokongoletsa komanso yoteteza, kukongoletsa malo amkati, kukonza kukongola ndi chitonthozo cha galimotoyo, komanso ali ndi ntchito yeniyeni yoteteza, kuteteza kapangidwe ka mkati mwa chitseko ku chilengedwe chakunja ndi kugwiritsidwa ntchito tsiku ndi tsiku .
Kunja kwa galimoto kulinso zinthu zina zofunika, monga bumper yakutsogolo, bumper yakumbuyo, siketi ya thupi, kuzungulira kwakunja, ndi zina zotero, zomwe pamodzi zimapanga mawonekedwe a galimotoyo, osati kungopereka chithandizo cha kapangidwe kake, komanso kukhudza kapangidwe kowongoka ndi chitetezo cha galimotoyo. Monga gawo lake, mbale yokongoletsera chitseko chakutsogolo, pamodzi ndi zinthuzi, zimaphatikizana kupanga chithunzi chonse cha galimotoyo, kusonyeza nzeru za kapangidwe kake ndi mulingo wa luso la galimotoyo.
Mbale yokongoletsa yakunja ya chipilala cha B, yomwe imadziwikanso kuti mbale yokongoletsa zitseko za chipilala cha B
1, mapulasitiki ambiri ndi opepuka, okhazikika pa mankhwala, ndipo sachita dzimbiri.
2, kukana bwino kukhudza.
3, ndi kuwonekera bwino komanso kukana kuvala.
4, kutchinjiriza bwino, kutentha kochepa.
5, mawonekedwe ambiri, utoto wabwino, mtengo wotsika wokonza.
6, kukana kutentha kwa pulasitiki kwambiri ndi kochepa, kuchuluka kwa kutentha komwe kumawonjezeka ndi kwakukulu, kosavuta kuyaka.
7, kukhazikika kwa mawonekedwe ndi kosauka, kosavuta kusintha.
8. Mapulasitiki ambiri amakhala ndi kukana kutentha kochepa ndipo amasweka kutentha kukakhala kotsika.
Mapulasitiki amatha kugawidwa m'magulu awiri a thermosetting ndi thermal plasticity, yoyamba siyingasinthidwe ndikugwiritsidwa ntchito, yachiwiriyo ikhoza kupangidwa mobwerezabwereza.
Pali mitundu iwiri ya kapangidwe ka pulasitiki ya polima:
Choyamba ndi kapangidwe ka mzere, ndipo kapangidwe ka polima kokhala ndi kapangidwe kameneka kamatchedwa mzere wa polima;
Chachiwiri ndi kapangidwe ka mtundu wa thupi, ndipo kuphatikiza kwa polima ndi kapangidwe kameneka kumatchedwa kuti polymer compound ya mtundu wa thupi.
Ma polima ena okhala ndi unyolo wa nthambi, otchedwa ma polima a nthambi, ali m'gulu la kapangidwe ka mzere. Ngakhale ma polima ena ali ndi maulalo olumikizana pakati pa mamolekyulu, sakhala olumikizana kwambiri, omwe amatchedwa kapangidwe ka netiweki ndipo ali m'gulu la kapangidwe ka thupi.
Mapangidwe awiri osiyana, omwe akuwonetsa makhalidwe awiri osiyana. Kapangidwe ka mzere (kuphatikiza kapangidwe ka unyolo wolumikizidwa ndi nthambi) polima chifukwa cha kukhalapo kwa mamolekyu odziyimira pawokha, ali ndi kusinthasintha, pulasitiki, amatha kusungunuka mu zosungunulira, kutentha kumatha kusungunuka, kuuma ndi kusweka kwa makhalidwe a ang'onoang'ono.
Kodi mungathetse bwanji phokoso losazolowereka la chitseko cha galimoto?
Ndizachilendo kuti chitseko chizilira molakwika galimoto ikagwiritsidwa ntchito kwa nthawi yayitali. Nthawi zambiri poyendetsa m'misewu yodzaza ndi mikwingwirima, chitseko chamkati cha galimoto chimaoneka chotseguka, zomwe zimapangitsa kuti phokoso likhale losazolowereka. Chitseko chamkati cha galimoto chimakhazikika ndi ma clip, ndipo chitseko chamkati chimakhala chomasuka poyendetsa mumsewu wodzaza ndi mikwingwirima, kotero kuti chitseko chamkati chiziwoneka chosazolowereka. Chitseko chamkati cha galimoto chikafunika kuchotsedwa kuti chikonzedwe, onetsetsani kuti simukuswa chitsekocho. Ngati chitseko chasweka, ndiye kuti mbale yamkati sidzakonzedwa bwino, ndipo padzakhala phokoso losazolowereka. Yankho la phokoso losazolowereka la chitseko ndi ili:
1. Onani ngati cholemberacho chili chomasuka
Choyamba, tiyenera kuwona ngati chomangira chomwe chili pa chitseko chili chomasuka. Ngati chomangiracho chili chomasuka, chidzayambitsa phokoso losazolowereka mkati mwa chomangiracho. Tingagwiritse ntchito screwdriver kapena chida chofanana nacho kuti tisunge chomangiracho pamalo pake kuti titsimikizire kuti bolodi lodulira silikumasuka. Ngati chomangiracho chawonongeka, chisintheni ndi chomangira chatsopano.
2. Sinthanitsani gulu lamkati
Ngati palibe vuto ndi chogwirira, ndiye kuti pakhoza kukhala vuto ndi mbale yamkati yokha. Pakadali pano, muyenera kusintha bolodi lamkati. Mukasintha bolodi lamkati, chotsani bolodi loyambirira lamkati ndikuyika latsopano. Dziwani kuti chogwiriracho chiyenera kukonzedwa panthawi yokhazikitsa kuti muwonetsetse kuti bolodi lamkati silidzasunthika.
Mwachidule, phokoso losazolowereka la chitseko ndi vuto lofala, komanso losavuta kuthetsa. Ingoyang'anani ngati chogwiriracho chili chomasuka, kapena sinthani chitseko chamkati. Ngati mukukumana ndi vuto la kulira kosazolowereka kwa chitseko, musachite mantha, mutha kuthetsa nokha.
Ngati mukufuna kudziwa zambiri, pitirizani kuwerenga nkhani zina patsamba lino!
Chonde tiimbireni foni ngati mukufuna zinthu zotere.
