Polyurethane utoto - utoto luso

M'zaka zapitazi asonyeza kuti chitukuko zamakono sasiya lachiwiri. Zinthu zambiri zokutira latsopano, bwino luso, kuwonjezera mwayi omanga ndi ogula muyenera. Mbali yaikulu ya chitukuko chamakono wasanduka zinthu yokumba - polyurethane. Ambiri ntchito, koma nthawi zambiri zikhoza kuoneka ngati m'malo a mphira zachilengedwe ndi mphira. Komabe, wapadera katundu wa polyurethane kuwalola m'malo pulasitiki ndipo ngakhale zitsulo.

Koma tsopano, tikambirana za mankhwala monga utoto polyurethane. nkhani zimenezi ali ndi makhalidwe mokwanira yeniyeni, ali mtengo wotsika, ndiponso kukamaomba mapindikidwe makina, mukhoza kupirira lonse kutentha osiyanasiyana ndipo ali ndi moyo mokwanira yaitali utumiki.

Polyurethane Utoto komanso yodziwika ndi digiri yapamwamba ya kukana kuti mphamvu yoipa ya zidulo ndi alkalis, mafuta zosiyanasiyana ndiponso petulo. Chotero utoto zokutira zikhoza kugawidwa m'magulu awiri: osakwatiwa-chigawo ndi ziwiri zikuluzikulu.

Monga dzina lake likunenera, kusiyana chachikulu pakati pa magulu awiri awa mu kuchuluka kwa zigawo zikuluzikulu. Chimodzi-chigawo utoto ndi kusintha mphira ngati utoto, zomwe zikuwoneka ngati utoto wamba. mankhwala amenewa amagulitsidwa pomwepo wokonzeka ntchito, kutanthauza kuti miyeso palibe zina kukonzekera ake, amene kwambiri kuchepetsa nthawi ya ntchito yokonza.

Pa nthawi yomweyo, anthu awiri zigawo zikuluzikulu zomwe imakhala ndi utoto polyurethane - kuchiritsa wothandizila ndi dongosolo la utomoni wonunkhira - zili muli osiyana. Iwo ayenera olumikizidwa kwa kufanana yeniyeni. Komabe, njira imeneyi lili ndi zinthu zambiri zabwino:

1. Pamene ❖ kuyanika ndi ndondomeko ya oipa kapena polymerization wa zikuchokera. Iye bwinobwino akuthamanga popanda chinyontho, choncho, zimenezi zingachitike limachititsa kuti kulabadira Pogoda zinthu monga matalala, mvula, chifunga.

2. Easy kutulutsa buku anakhumba nkhani utoto. Kukhala ndi mwayi kuswana yekha chofunika kuchuluka kwa inki angathe kuchepetsa kwambiri mowa wake ndipo chotero, kupulumutsa pa kugula zipangizo. Komabe, polyurethane utoto bwino kusungidwa mu dilution wa nthawi yaitali. Ngakhale akamaziwononga.

3. Ntchito chifukwa ndi olimba ❖ kuyanika. Pa nkhani imeneyi, ziwiri zikuluzikulu ❖ kuyanika ali ndi mwayi kwambiri pa chigawo mwachizolowezi umodzi.

Choncho, polyurethane ❖ kuyanika amapereka avale kugonjetsedwa zotanuka ❖ kuyanika amene ali mokwanira kugonjetsedwa ndi kuwononga makina ndi mankhwala, ndi kukamaomba dzuwa. Chotero ❖ kuyanika ndi chimagwiritsidwa inafikira ntchito amagwiritsidwa ntchito mwanjira: n'zotheka ndi kunja ndi zojambula mkati.
