Pamene kasitayo yawonongeka, njira yodziwika bwino yoiwonera ndikuwona kuchuluka kwa pamwamba pa gudumu lawonongeka. Komabe, palinso vuto lina losiyana kwambiri lomwe limapezeka m'munda: pamwamba pa tayala pamakhala pomata, lofewa, ndipo pamakhala ming'alu yaying'ono, ngakhale kung'ambika pang'ono ikakanda ndi manja, ngakhale kuti kasitayo sinagwiritsidwe ntchito kwa nthawi yayitali.
Chodabwitsa kwambiri n'chakuti zipangizo zina, ngakhale kuti sizigwiritsidwa ntchito kawirikawiri, zimakumananso ndi vutoli.
Pakadali pano, chifukwa chake sichingakhale lingaliro lachikhalidwe la "kutha," koma kukalamba kwa hydrolytic kwa zinthu zina zamagudumu pansi pa mikhalidwe inayake.
1. Kodi "hydrolysis" ya zinthu za gudumu la castor ndi chiyani?
Mwachidule, zikutanthauza kuti pambuyo pokumana ndi chinyezi kwa nthawi yayitali kapena malo onyowa, kapangidwe ka mankhwala a zinthu zina za polima kamasintha pang'onopang'ono.
Kusintha kumeneku kumasiyana ndi momwe pamwamba pa gudumu "pakuphwanyidwira" ndi nthaka.
Kuwonongeka nthawi zambiri kumachitika pamalo olumikizirana pakati pa gudumu ndi nthaka, pomwe hydrolysis imakhudza kusintha pang'onopang'ono kwa zinthu zomwe zili mkati mwake, kotero zimatha kupitilira kukula ngakhale zidazo zitakhala zosasunthika kwa nthawi yayitali.
Ichi ndichifukwa chake ma casters ena amaoneka ngati "osagwiritsidwa ntchito," koma amapeza kuti malo awo ozungulira mawilo adawonongeka kwambiri atapezeka patapita zaka zambiri.
2. Kodi ma polyurethane casters onse amaopa hydrolysis?
Sizingatheke kugawidwa m'magulu onse.
Polyurethane si chinthu cholimba kwathunthu koma ndi dongosolo la zinthu zambiri. Machitidwe osiyanasiyana a zinthu zopangira, mapangidwe, ndi njira zopangira zitha kuwonetsa kusiyana kwakukulu pakukana kwa hydrolysis.
Chifukwa chake, sikolondola kungonena kuti "mawilo a polyurethane sangagwiritsidwe ntchito m'malo ozizira."
Gawo lofunika kwambiri ndikufotokozera momveka bwino panthawi yosankha ngati ma casters adzakumana ndi madzi kwa nthawi yayitali, malo omwe ali ndi chinyezi chambiri, njira zotsukira, kapena nthunzi, kenako sankhani njira yoyenera kwambiri yogwiritsira ntchito zinthu kutengera momwe ntchito ikuyendera.
Kungonena kuti “Ndikufuna gudumu la PU” kwa wogulitsa sikupereka chidziwitso chokwanira.
3. N’chifukwa chiyani malo otentha kwambiri komanso chinyezi chambiri ndi ofunika kwambiri?
Mavuto a hydrolysis amagwirizana kwambiri ndi momwe zinthu zilili m'chilengedwe.
Ngati zinthu zina zophikidwa m'madzi zikakhala pamalo onyowa kwa nthawi yayitali, nthawi yomweyo zikakhala pamalo otentha kwambiri, kukalamba kwa zinthu zina kungakhale kofunikira kwambiri.
Mwachitsanzo, malo opangira zinthu omwe amafunika kutsukidwa pafupipafupi, malo osungiramo zinthu omwe amakhala ndi chinyezi kwa nthawi yayitali, zida zoyeretsera, malo ena opangira chakudya, ndi malo ogwirira ntchito okhala ndi chinyezi, ayenera kufotokozedwa pasadakhale panthawi yosankha.
Nthawi zina mphamvu ya makina yonyamula katundu wa ma casters si vuto konse, ndipo ndi malo omwe amaletsa kugwiritsa ntchito kwawo.
4. Kodi kusiyana pakati pa hydrolysis ndi kuvala wamba ndi kotani?
Kuvala kwabwinobwino nthawi zambiri kumakhala ndi mawonekedwe osiyana olumikizana.
Pambuyo pogubuduza pamwamba pa gudumu kwa nthawi yayitali pansi, pamwamba pa ntchitoyo pang'onopang'ono pamakhala kuonda, zomwe ndi vuto losavuta kugwiritsa ntchito.
Pamene zinthuzo zikukalamba kwambiri, zimatha kuwoneka ngati pamwamba pa gudumu lomata, kutayika kwa kusinthasintha koyambirira, kusweka kwa pamwamba, ufa wokhazikika, kapena kusweka kwa block.
Ngati ma casters sanagwiritsidwe ntchito kwambiri koma akuwonetsa kusintha kwakukulu kwa momwe zinthu zilili, malo ofufuzira ayenera kukulitsidwa kuchoka pa "kuwonongeka" mpaka pamavuto okhudzana ndi kugwirizana kwa zinthu ndi chilengedwe.
5. N’chifukwa chiyani anthu ogulitsa masheya nawonso angakhale ndi mavuto?
Kungoti ma caster sanayikidwe pazida sizikutanthauza kuti zinthuzo sizidzasintha.
Malo osungiramo zinthu m'nyumba yosungiramo zinthu ndi ofunikiranso.
Ngati zinthu zina za polima zitha kukalamba pang'onopang'ono ngati zitayikidwa pamalo otentha kwambiri, chinyezi, kuwala kwa dzuwa mwachindunji, kapena malo osayenera kusungiramo zinthu kwa nthawi yayitali.
Chifukwa chake, polemba zinthu zakale kwa nthawi yayitali, sikulimbikitsidwa kungoyang'ana ngati phukusi latha.
Musanayigwiritsenso ntchito, pamwamba pa gudumu mutha kuyang'ana ngati pali kukanikira, ming'alu, kuuma, kufewa, kapena zolakwika pamwamba.
Makamaka pazinthu zomwe sizinagulitsidwe kwa nthawi yayitali, ndikofunikira kuchita kafukufuku wosavuta.
6. Mukasankha zida zoyeretsera pafupipafupi, funsani funso lina
Anthu ambiri ogwira ntchito yogula zinthu amauza ogulitsa kuti:
Chipangizochi chimagwiritsidwa ntchito m'nyumba
Koma mkhalidwe wa 'mkati' ndi waukulu kwambiri.
Nyumba yosungiramo zinthu nthawi zonse imakhala mkati, ndipo malo okonzera chakudya omwe amafunika kutsukidwa tsiku lililonse nawonso ali mkati. Zofunikira pa zipangizo zopangira zinthu m'malo awiriwa zingakhale zosiyana kwambiri.
Chifukwa chake, ngati zipangizozo zikufunika kutsukidwa pafupipafupi, kufotokozera kwina kuyenera kuperekedwa pa kuchuluka kwa kuyeretsa, ngati madzi amasonkhana kwa nthawi yayitali, ngati zotsukira zimagwiritsidwa ntchito, komanso ngati mawilowo akhala onyowa kwa nthawi yayitali.
Chidziwitsochi nthawi zambiri chimakhala chamtengo wapatali kuposa kungouza ogulitsa za momwe amagwiritsira ntchito m'nyumba.
7. Ndapeza malo olakwika a gudumu, musafulumire kungosintha ndi chitsanzo chomwecho
Ngati gulu la mawilo likuwonetsa kumamatira, kusweka, kapena kugwa kofanana, njira yosavuta ndiyo kuwasintha ndi atsopano.
Koma ngati ma casters atsopano akugwiritsabe ntchito makina omwewo ndipo malo omwe ali pamalopo sakusintha, mavuto ofananawo angabwerenso.
Njira yabwino ndiyo kutsimikizira kaye kuti:
Kodi chipangizochi chimakhala ndi chinyezi chotani kwa nthawi yayitali?
Kodi mumakumana ndi madzi pafupipafupi?
Kodi pali njira yoyeretsera?
Kodi pali nthunzi yamadzi yomwe imatuluka nthawi yayitali pafupi ndi mawilo?
Kodi malo osungiramo zinthu m'nyumba yosungiramo zinthu ndi oyenera?
Mukatsimikizira zinthu izi, onani ngati zinthu zomwe zili pamwamba pa gudumu ziyenera kusinthidwa.
Lembani kumapeto
Kulephera kwa ma casters sikuti nthawi zonse kumachitika chifukwa chogwiritsa ntchito mopitirira muyeso.
Mawilo ena amayenda pafupipafupi tsiku lililonse, koma pamwamba pa mawilowo pamakhalabe pabwino; Mawilo ena sangagwiritsidwe ntchito pafupipafupi, koma amatha kukalamba msanga chifukwa cha malo ndi zinthu zosagwirizana.
Iyi ndi mfundo yomwe nthawi zambiri imanyalanyazidwa posankha oponya:
Kuwonjezera pa kufunsa kuti chipangizochi ndi cholemera bwanji komanso kuti chimagwira ntchito pa nthaka yotani, muyeneranso kufunsa malo omwe ma casters amakumana nawo tsiku lililonse.
Pamene gudumu likuyamba kukanikiza, kusweka kapena kugwa, ndibwino kuti musanene nthawi yomweyo kuti ndi "kuipa kwa zinthu." Kuyang'anitsitsa malo ogwiritsira ntchito ndi kusungira nthawi zambiri kumapangitsa kuti zikhale zosavuta kupeza chifukwa chenicheni.
Kuti mudziwe zambiri, chonde musazengereze kulankhulana ndi Gulu la GLOBE!
