Nthawi zina timayenera kupempha zofunikira pazomwe timayenda. Kuwonjezera pa mitundu yosiyanasiyana ya pansi, timakhala ndi mwayi wotonthoza ndi chithandizo chamakono zamakono.
Kodi ndizomwe zili zokhazikika pansi pa polyurethane?
Pulogalamu ya polyurethane yodzaza pansi imagwiritsidwa ntchito ku konkire kapena simenti screed. Kumtunda kunkawoneka kosalala ndi kokongola, kumatsukidwa ku mitundu yosiyanasiyana ya kuipitsa, kupukutidwa ndikugwiritsidwa ntchito potsamira poyambira polima. Ntchito zowonongeka zowonjezereka zimapangitsanso kukonzekera kwa zipangizo zosiyana ndikuwonjezera moyo wautumiki. Kutalika kwa gawoli kumapangidwira mtundu wa pansi ndi machenga ochepa mpaka mamita 30. Monga momwe akugwiritsira ntchito, amagwira ntchito zing'onozing'ono zothetsera vutoli, kutsatira ndondomeko yokonzekera ndikugwiritsira ntchito ku gawo lapansi. Pa gawo lina la pamwamba pa nthaka ndilokhazikika pamtima, koma kuyembekezera kuti lidzakhala lokha siloyenera. Mafakitale monga spatula kapena thandizo losavuta kuti agwire ntchito mwaulemu pa siteji ya kutsanulira, ndipo magalasi a makala amachotsa mpweya umene umathandiza kupanga mapangidwe.
Makhalidwe apansi a polyurethane
Pafupifupi mitundu yonse ya polyurethane yokhazikika pansi ili ndi makhalidwe abwino monga kukana mankhwala, kusintha kwa kutentha, katundu wamtundu wapamwamba ndi zovuta zosiyanasiyana. Kuthira kwa madzi kumalola kugwiritsa ntchito malo amtundu awa m'malo okhala ndi chinyezi chachikulu, komanso kumasuka koyeretsa ndi kukonza kuti akhale pansi mwakuya. Wogulayo ali ndi mwayi wosankha pulasitiki osati kokha mwa kukula kwake, komanso mu chikhalidwe cha mankhwala, chiwerengero cha kudzazidwa ndi mtundu wa kudzaza, zomwe zimachitika ngati quartz, corundum kapena chipsera cha mphira. Zokongoletsera zapamwamba zimakongoletsa kuti zigwiritsidwe ntchito pakhomo payekha m'madera omwe ali ndi magalimoto akuluakulu komanso chinyezi.
Polyurethane pansi mkati mwa nyumbayo
Chophimba, choyambirira chinapangidwira makampani ogulitsa mafakitale, muzipinda sizigwiritsidwa ntchito nthawi zambiri. Akatswiri amalangiza kuti achepetse ntchito yake kukhitchini, mu bafa ndi chimbudzi. Koma, mafashoni amachititsa wina, kotero kuwala kofiira ndi matt polyurethane komweko kumayambira pansi kunayamba kugula ku chipinda choyendamo ndi chipinda. Poyambirira, mosamala, adayambitsa maziko ena. M'kupita kwanthawi, kukongoletsa kunayesedwa ndikusintha.
Kusasuntha kophatikizana ndi mitundu yosawerengeka ya mitundu kumapangitsa kulumikizana kwapadera kwapakati. Chidwi chapadera chimapangidwa ndi 3-D odzimangirira pansi. Chithunzi chachitatu chimapezeka pamutu uliwonse ndi cholinga chilichonse. Mwachitsanzo, miyala yam'madzi, nsomba zazikulu ndi ndulu zimayendetsedwa bwino mu malo osambira. Chithunzi choposa chachikulu cha zitatu chimaonedwa kuti ndi chofanana chomwe chimapangidwa kuchokera kumalo alionse a malingaliro. Kuwonjezera apo, teknoloji imakulolani kuti mupange chinyengo cha zinthu zina.
Kuipa kwa kuvala
Kusakhala ndi chizoloŵezi chopanga uluso wa pansi ndi kovuta kwambiri. Chisamaliro chapadera chiyenera kuperekedwa ku ntchito yokonzekera, yomwe imatsimikizira kuti ndi yodalirika bwanji. Maziko ayenera kukhala mwamtheradi ngakhale opanda chidutswa chimodzi cha fumbi. Anthu ambiri amaganizira zokhala pansi pamtengo wokondweretsa kwambiri kuti awone. Komanso, yankho lokonzekera kuponyedwa liri ndi poizoni.
Pulogalamu ya polyurethane yodzaza pansi ikuwoneka bwino mkati mwa mkati. Komabe, ndi koyenera kwambiri kugwiritsira ntchito kalembedwe wamakono, mwachitsanzo, zamakono kapena zojambula.
