Chifukwa chiyani utoto wagalimoto ukuphwanyidwa?

Utoto wa thupi umanyamula osati zokongoletsera zokha, komanso katundu wothandiza: umateteza chitsulo kuti chisawonongeke ndi kuwonongeka kwina. Choncho, teknoloji yogwiritsira ntchito iyenera kuwonedwa mosamalitsa. Apo ayi, zolakwika zamtundu, makamaka ming'alu, zikhoza kuwoneka.

Ming'alu yomwe imawoneka mu utoto wa thupi imatha kugawidwa m'magulu awiri:

• kupezeka pa nthawi ya ntchito;
• amawonekera mwamsanga atatha kujambula (amatchedwanso tsitsi).

Kupweteka pa nthawi ya ntchito

Utoto wa Acrylic umagwiritsidwa ntchito kwambiri kuphimba thupi lagalimoto. Imasiyanitsidwa ndi mphamvu zake komanso kulimba kwake. Komabe, utoto wodalirika wotere nthawi zina umasweka. Nthawi zina izi zimachitika chifukwa cha zolinga, mwachitsanzo, kuwonongeka kwa thupi chifukwa cha ngozi. Kuonjezera apo, zolakwika zimatha kuchitika chifukwa chogwiritsa ntchito mankhwala osavomerezeka pakutsuka galimoto. Nthawi zina utoto wa acrylic umasweka akakhala ndi kusintha kwa kutentha kapena chifukwa chokhala ndi dzuwa kwanthawi yayitali pagalimoto. Ma reagents omwe amagwiritsidwa ntchito pochiza misewu m'nyengo yozizira amathanso kukhala ndi zotsatira zoyipa pa utoto.

Utoto wa Acrylic pojambula magalimoto

Komabe, utoto wa acrylic womwe umagwiritsidwa ntchito molingana ndi zofunikira zaukadaulo nthawi zambiri umalimbana ndi zovuta zotere. Nthawi zambiri, zolakwika zimachitika ndi penti yopanda bwino. Kuphatikiza apo, zophwanya zitha kuchitika pafakitale komanso m'mabwalo achinsinsi.

ming'alu ya tsitsi

Dzinali likufotokozedwa ndi mawonekedwe ake ndi makulidwe: amawoneka ngati tsitsi lalitali. Amawonekera pamalo omwe angopentidwa kumene ndipo amawonekera bwino pokhapokha utotowo ukauma. Zimakhala zosatheka kuziwona nthawi yomweyo (chifukwa chake zimawonedwa ngati zovuta kwambiri). Pokhala ang'onoang'ono koyambirira, pakapita nthawi amatha kukula kukhala maukonde odabwitsa.

Zophwanya pokonzekera maziko

Zomwe zimayambitsa kuoneka kwa ming'alu yayikulu ndi yaying'ono ndizofanana. Chimodzi mwazofala kwambiri ndikukonzekera kosayenera kwa pamwamba musanajambule (mwachitsanzo, ngati utoto wakale wosakanizika wa utoto sunachotsedwe kwathunthu).

Chifukwa china chomwe utoto umang'amba pambuyo pojambula ukhoza kukhala ziyeneretso zosakwanira za wojambula. Makamaka, zolakwika zimatha kuchitika chifukwa chosasunga milingo pokonzekera utoto wamagulu awiri, komanso kugwiritsa ntchito zinthu zopanda pake.

Nthawi zina vuto limakhala poyambira kapena kugwiritsa ntchito. Ndikofunikiranso kutsata mosamalitsa kuchuluka kwa zigawo ndi malamulo ogwirira ntchito ndi zinthuzo. Opanga nthawi zambiri amaphatikiza malangizo atsatanetsatane kuzinthu zomwe ziyenera kuwerengedwa mosamala. Kotero, mwachitsanzo, nthaka ya acrylic mu mitsuko iyenera kugwedezeka nthawi zonse, chifukwa chifukwa cha kukhazikika kwa zigawo zolemera pansi, katundu wa zinthuzo amatayika.

Utoto wa Acrylic nthawi zambiri umang'ambika m'malo omwe putty amagwiritsidwa ntchito kwambiri. Akatswiri samakhala nthawi zonse amakwaniritsa miyezo ya ntchito yawo. Mwachitsanzo, mano akulu nthawi zina amachotsedwa osati kuwongola, koma ndi putty. Kupanikizika kochitidwa ndi kuyanika zokutira pamwamba kumawerengedwa pazitsulo. Putty samakana, amafota ndi kusweka. Izi zimabweretsa kupanga ming'alu pambuyo poyanika.

Pokonzekera multi-component putty, ojambula nthawi zambiri amaphwanya malamulo okhudzana ndi kuchuluka kwa magawo. Mwachitsanzo, kuti muchepetse kuyanika, onjezerani zowuma kwambiri. Pamene ntchito putty ndi woonda wosanjikiza zoipa zotsatira zambiri sizichitika. Koma zikachuluka, zikauma, zimasweka.

Zina zomwe zingayambitse

Kuphatikiza pa kusakonzekera bwino pamwamba, kusweka kungayambitsidwe ndi:

• utoto umagwiritsidwa ntchito wandiweyani kwambiri;
• kufulumizitsa kuyanika kwa primer (mwachitsanzo, chifukwa cha kukakamizidwa kwa mpweya);
• kugwiritsa ntchito chosungunulira cholakwika;
• kusakanizika kosakwanira kwa zokutira.

Momwe mungapewere kusweka

Pofuna kupewa utoto wa acrylic kuti usaphwanyeke, m'pofunika kukonzekera bwino pamwamba pa kujambula. Thupi liyenera kutsukidwa mpaka chitsulo, ndiyeno liyeretsedwe bwino. Pochotsa mano, kusalaza kuyenera kugwiritsidwa ntchito momwe mungathere kuti putty wosanjikiza akhale woonda kwambiri. Pokonzekera pamwamba, chidwi chokwanira chiyenera kuperekedwa ku malo aliwonse olakwika. Chilema chilichonse chingapangitse utoto kung'ambika pakapita nthawi mutatha kujambula.

Ndikofunikira kutsatira mosamalitsa malangizo a opanga, kuphunzira mosamala kapangidwe kazinthu zomwe zimagwiritsidwa ntchito (penti ya acrylic, primer, putty, varnish). Kuti muyese kuchuluka kwake, tikulimbikitsidwa kugwiritsa ntchito chidebe choyezera, chomwe, monga lamulo, chimamangiriridwa pa phukusi. Ngati zofunikira zonse zikwaniritsidwa, ngati ming'alu ikuwonekera pa penti, mwiniwake wa galimotoyo adzatha kudziwa chifukwa chake ming'aluyo inawonekera komanso kwa ndani kuti anene.

Momwe mungakonzere ming'alu

Kusweka kwa penti ndi vuto lalikulu. Padzafunika khama lalikulu kuti athetse vutoli. Ngati galimotoyo ili pansi pa chitsimikizo, mwamsanga zizindikiro zoyamba za ming'alu zikapezeka, tikulimbikitsidwa kuti muyankhule ndi wogulitsa. Popanda mwayi wotere, vutoli liyenera kuthetsedwa lokha (kapena ndalama zanu). Mosasamala kanthu za chifukwa chake utotowo waphwanyidwa, malo owonongekawo ayenera kuwathira mchenga pansi. Kuti muchite izi, gwiritsani ntchito chopukusira kapena sandpaper ndikuwonjezeka pang'onopang'ono kukula kwa tirigu (kuchokera pa 100 mpaka 320 mayunitsi). M'pofunika kuchotsa zigawo zonse zowonongeka (ndizofunika kuzichotsa kuzitsulo).

Pambuyo pa etching, acrylic putty ndi primer amagwiritsidwa ntchito. LKP imagwiritsidwa ntchito pamwamba (ndikoyenera kuti utotowo ndi acrylic). Kutengera dera lomwe lawonongeka, chithandizocho chimatengera:

• malo osiyana;
• chinthu chathunthu (mwachitsanzo, hood kapena fender);
• thupi lonse

Pogwiritsa ntchito utoto wapamwamba kwambiri, mikhalidwe yoyenera (kutentha, kuyatsa, chinyezi, etc.) iyenera kupangidwa m'chipindamo. Ndicho chifukwa chake eni magalimoto ambiri amakonda kupenta m'mabungwe apadera. Komabe, ntchitoyi ikhoza kuchitidwa paokha. Koma panthawi imodzimodziyo, zofunikira zonse zamakono ziyenera kuwonedwa mosamalitsa.
