Ukulungiswa kwelayili kudlala indima ebalulekileyo ekuhlobiseni ingaphakathi kunokuhlobisa izindonga okanye ukuthenga ifenitshala enhle. Ukongezelela, umoya ococekileyo kunye nococeko uvakalelwa ezindlwini apho kuphakanyiswe khona imithi yamatye phezu komhlaba. Kodwa kude kube kutshanje, indlela enjalo yokuhlobisa idilesi yayifumaneka kuphela kubambalwa. Oku bekubangelwa iindleko eziphezulu zokuthengwa kweemithi zamatye, kunye nokuxakeka kofakelo lwabo. Nangona kunjalo, emva kokuvela kweemveliso ze-polyurethane kwiimarike namhlanje, imeko ekhoyo iguqule ngokubanzi, kwaye iipolisi zokhuni ze-polyurethane zikhuphisana ngokukodwa nemveliso eyenziwa ngezinto zendalo.
Iipolyurethane imithi ephakamileyo
Iimitha ezenziwe nge-polyurethane zixelisa ngokupheleleyo ukuqala kobunzima bomthi, kwaye ngeendlela ezininzi zizuza kwizakhiwo zokhuni:
- Zilula kwaye zilula ukufaka;
- xabiso labo liphantsi kakhulu;
- i-polyurethane ayithinteki ngexesha, ayesabi ukwanda kwamanyathelo kunye nenyango yezinambuzane;
- kwizakhiwo ezingenanto kulula ukufihla iintlobo zonxibelelwano kunye neencingo.
Iipolyurethane imitha zingayifumana isicelo sayo ngaphakathi kwiphina isitayela. Konke kuxhomekeka kwindlela abahlotshisiwe ngayo:
- Kwiindawo zangaphakathi zendawo, iintambo ezihlotswe ngemifanekiso okanye imidwebo zifanelekileyo;
- kwisitayela selizwe okanye kwisihlalo, iipolyurethane zixhobo ezifake umthi;
- nakweyiphi na indlela yohlanga okanye isiqendu se-loft, imithando kunye nokuthungwa kwemithi yeklasi iya kubonakala ihambelana;
- Ubunzima kunye nokuthintela kwanoma yiyiphi na indlela yamanamhlanje ingagxininiswa ngamacwecwe abhalwe ngezimpawu ezimhlophe, ezimnyama okanye ezimnyama;
- ukuhlaziya igumbi nokuphakamisa imizwelo, iipolisi ze-polyurethane zemihlaba zifakwe kwiimbala eziqhaqhaqhazelayo kunye nemibala;
- Ubumbano kunye nesitayela esibukrakra sobugcisa obugqityiweyo sigxininiswa ngumbonakalo wensimbi wendawo yokwakhiwa kwelitye ngokudibanisa nomngxube ococekileyo ngokumalunga neendonga zezitena ezingenanto;
- Ukulula kunye nokukhanya kweemithi, ezenziwe ngezimhlophe, zifanelekile kwiProvence yesiFrentshi.
Ngaloo ndlela, i-polyurethane falshalki ihambelana nantoni nayiphi na ingaphakathi, kungakhathaliseki ukuba yinkalo yobunzima bayo kunye nokuzithemba. Nangona kunjalo, ungazami ukuhlobisa isakhiwo ngeepiliti eziphantsi kunye neepolisi ze-polyurethane. Emva kwayo yonke into, i-drawback kuphela yamaplanga okuyila ikwazi ukubonakala ngaphantsi komhlaba.
