Makasitomala ambiri amafunsa funso lomwelo posankha ma casters: ndi chiyani chabwino, mawilo a polyurethane kapena mawilo a rabara?
Ndipotu, palibe yankho limodzi pa funsoli. Zipangizo zonsezi zili ndi ubwino wake, chofunika si amene ali "wotsogola kwambiri", koma amene ali woyenera kwambiri malo enieni ogwiritsira ntchito. Posankha, cholinga chiyenera kukhala pa zofunikira zonyamula katundu, momwe nthaka ilili, kuchuluka kwa momwe igwiritsidwira ntchito, zofunikira phokoso, ndi bajeti.
Mwachidule, ngati zipangizozo zili ndi katundu wambiri, zimagwiritsidwa ntchito pafupipafupi, mtunda wautali, kapena zinthu zovuta kugwira ntchito monga madontho a mafuta ndi mankhwala pamalopo, mawilo a polyurethane nthawi zambiri amakhala oyenera; Ngati cholinga chachikulu chikugwiritsidwa ntchito poyamwa mafunde, kuchepetsa phokoso, ndi kuteteza nthaka, ndipo katundu wa zidazo si wokwera kwambiri, mawilo a rabara nthawi zambiri amakhala odalirika kwambiri.
1. Makhalidwe akuluakulu a mawilo a polyurethane
Mawilo a polyurethane amaphatikiza mphamvu yonyamula katundu, kukana kuwonongeka, ndi kuyendetsa mopepuka, zomwe zimapangitsa kuti akhale mtundu wofala wa mawilo m'mafakitale ndi m'nyumba zosungiramo katundu.
Choyamba, mawilo a polyurethane amakhala ndi kukana kwakukulu kwa kuwonongeka ndipo nthawi zambiri amakhala olimba kuposa mawilo wamba a rabara omwe amagwiritsidwa ntchito pafupipafupi, kukankhira kutali, komanso m'malo ovuta. Makamaka m'malo omwe kuli madzi, mafuta, kapena mankhwala enaake pansi, kukhazikika kwake kudzaonekera bwino.
Kachiwiri, mawilo a polyurethane ali ndi kulimba bwino ndipo sasinthasintha mosavuta chifukwa cha kupsinjika, zomwe zimapangitsa kuti akhale oyenera kugwiritsidwa ntchito pazida zapakati komanso zolemera. Nthawi yomweyo, kukana kwake kugwedezeka kumakhala kochepa, zomwe zimapangitsa kuti zikhale zosavuta kukankhira ndikugwiritsa ntchito magalimoto oyendetsera zinthu, magaleta ogwiritsira ntchito zida, zida zosungiramo zinthu, ndi zida zina zodzichitira zokha.
Kuphatikiza apo, mawilo a polyurethane nthawi zambiri sasiya zizindikiro zakuda pansi, zomwe zimapangitsa kuti azikhala ochezeka kwambiri m'malo omwe ali ndi zofunikira zambiri monga pansi pamatabwa, pansi pa epoxy, zipatala, ndi malo ochitirako chakudya.
Komabe, mawilo a polyurethane alinso ndi zofooka. Chifukwa cha zinthu zake zolimba, kuyamwa kwake ndi kutsekeka kwake nthawi zambiri sikwabwino ngati mawilo a rabara. Akakumana ndi nthaka yosagwirizana, kuthekera kwake kuyamwa kugwedezeka kumakhala kochepa; M'malo ena, phokoso logwirira ntchito lingakhalenso lokwera pang'ono. Kuphatikiza apo, ndalama zopangira ndi zopangira nthawi zambiri zimakhala zokwera kuposa za mawilo a rabara, kotero mtengo nthawi zambiri umakhala wokwera.
2. Makhalidwe akuluakulu a mawilo a rabara
Ubwino wa mawilo akuluakulu a rabara uli mu kusinthasintha kwawo bwino, mphamvu yodziwika bwino yoyamwa ma shock, komanso kugwiritsa ntchito mopanda phokoso.
Ponyamula zida zolondola, zida zamagetsi, zinthu zamagalasi, ndi zinthu zina zomwe zimakhudzidwa ndi kugwedezeka, mawilo a rabara amatha kutetezera bwino kugunda kwa nthaka ndikuchepetsa kugundana kwa magundu. Nthawi yomweyo, kukhudzana kwake ndi nthaka kumakhala kofewa, ndipo ogwiritsa ntchito amakhala bwino m'malo monga zipatala, maofesi, ndi malaibulale omwe amafunikira kuwongolera phokoso lalikulu.
Kuphatikiza apo, mawilo a rabara nthawi zambiri amakhala abwino, ndipo amagwira bwino kwambiri pamalo onyowa kapena osalala. Kuphatikiza apo, ndi njira zopangira zokhwima komanso zinthu wamba zopangira, mawilo a rabara ali ndi zabwino zambiri pamtengo wotsika pazinthu zambiri zopepuka.
Komabe, pankhani ya kukana kutopa ndi mphamvu yonyamula katundu, mawilo a rabara nthawi zambiri sali abwino ngati mawilo a polyurethane. Akakumana ndi katundu wolemera, kugwiritsidwa ntchito pafupipafupi, kapena malo ovuta kwa nthawi yayitali, mawilo a rabara amatha kutopa ndi kusinthasintha chifukwa cha kupanikizika kwambiri, zomwe zimakhudza nthawi yawo yogwirira ntchito.
Kuphatikiza apo, kukana kwa mawilo a rabara nthawi zambiri kumakhala kwakukulu, zomwe zimapangitsa kuti kukankhira kukhale kovuta kwambiri; Mawilo ena akuda a rabara amathanso kusiya zizindikiro pansi. Ngati atayikidwa pamalo a ultraviolet, ozone, kapena mafuta kwa nthawi yayitali, zipangizo za rabara zimakhalanso zosavuta kukalamba, kusweka, ndi mavuto ena.
3. Momwe mungasankhire pakati pa mawilo a polyurethane ndi mawilo a rabara
Ngati chipangizo chanu chikugwiritsidwa ntchito kwambiri kapena chikufunika kusunthidwa pafupipafupi tsiku lililonse, mawilo a polyurethane angakhale oyenera kwambiri. Ndi osavuta kusweka, ali ndi mphamvu yonyamula katundu wambiri, ndipo ndi osavuta kugwiritsa ntchito. Ponseponse, ndi oyenera kwambiri zida zamafakitale, magalimoto osinthira zinthu, magalimoto osungiramo katundu ndi ogwirira ntchito, ndi zina zotero.
Ngati pali madontho a mafuta, zotsukira, mankhwala, kapena zofunikira kwambiri pakuyeretsa pansi pamalopo, mawilo a polyurethane nthawi zambiri amakhala abwino kwambiri.
Ngati cholinga chanu chili pa kuyamwa kwa mantha, kuchepetsa phokoso, ndi kuteteza katundu, mawilo a rabara adzakhala oyenera kuganizira. Mwachitsanzo, poyendetsa zida zolondola, zida zachipatala, zida zowonetsera, ndi zina zotero, mawilo a rabara ali ndi ubwino wambiri pakusunga ndi kuchepetsa phokoso.
Ngati katundu wa zida si wokwera kwambiri, kuchuluka kwa momwe zimagwiritsidwira ntchito ndi kwapakati, ndipo bajeti yake ndi yochepa, mawilo a rabara nthawi zambiri amakhala chisankho chotsika mtengo.
4. Ndikofunikira kuyang'ana kwambiri mfundo izi posankha mitundu yeniyeni
Yang'anani kuchuluka kwa katundu. Zipangizo zikalemera kwambiri, zimafunikira kwambiri kuti mawilo azigwira ntchito bwino komanso kuti asasinthe.
Kachiwiri, yang'anani pansi. Mayeso a nthaka yolimba amawononga mphamvu zambiri, pomwe nthaka yosalala imagogomezera kwambiri bata, kukana kutsetsereka, ndi kuteteza nthaka.
Chachitatu, yang'anani chilengedwe. Kaya chikugwirizana ndi mafuta, madzi, kapena mankhwala, komanso kaya chikugwiritsidwa ntchito panja kwa nthawi yayitali kapena pafupipafupi, zonsezi zimakhudza kusankha zinthu.
Chachinayi, yang'anani cholinga chogwiritsira ntchito. Kaya chikhale cholimba komanso chopulumutsa ntchito, kapena chopanda phokoso komanso choletsa mantha, cholinga chogwirizana ndi zolinga zosiyanasiyana chimasiyana.
Chachisanu, onani bajeti. Pazida zomwe zimagwira ntchito nthawi yayitali, pafupipafupi, komanso zolemera, kusankha zipangizo zoyenera nthawi zambiri ndikofunikira kwambiri kuposa kungochepetsa ndalama zogulira.
Chidule
Palibe kusiyana kwakukulu pakati pa mawilo a polyurethane ndi mawilo a rabara, pokhapokha ngati ali oyenera momwe ntchito ikuyendera panopa.
Mawilo a polyurethane ndi oyenera kuyendetsa galimoto molemera, mosawonongeka, mtunda wautali, komanso kugwiritsa ntchito zinthu zovuta zachilengedwe; Mawilo a rabara ndi oyenera kwambiri pazochitika zomwe zimafuna kuyamwa kwa mantha, kuchepetsa phokoso, kukana kutsetsereka, komanso kuwongolera ndalama.
Pogula zinthu zenizeni, tikulimbikitsidwa kupanga chigamulo chokwanira kutengera kulemera kwa zida, kuchuluka kwa momwe zimagwiritsidwira ntchito, momwe nthaka imagwirira ntchito, komanso bajeti. Kusankha zinthu zoyenera sikuti kumangowonjezera luso la ogwiritsa ntchito, komanso kumachepetsa ndalama zokonzera ndi kusintha zinthu mtsogolo.
