Zomatira kwa thovu ndi makhalidwe aika

Kutchula koyamba za mphira thovu ndiwo anawerengedwa mwa Germany mu 1941, komwe adalandira mwangozi thobvu polyurethane. Mophiphiritsa, chithovu - mfundo ndi dongosolo porous wodzazidwa ndi mpweya. Kuchuluka kwa zinthu izi lonse moti labwino bwino psinjika chifukwa elasticity ake, ali breathability kwambiri ndi kuisunga mawonekedwe wapachiyambi. Nthawi zambiri ntchito mipando, zinthu zamasewera, mipando galimoto, zipangizo kutchinjiriza ndi zidole zofewa. Komanso tsiku ndi tsiku kuti ali mochulukitsa ntchito zake kubala zosiyanasiyana odzigudubuza utoto, thonje, kutsuka mbale ndi kuyeretsa. Ku Ulaya, nkhaniyi naye ntchito ngati mankhwala ma CD.

ntchito ulimbo

kuti thovu zomatira ndi mwachilungamo m'mbali ntchito. Pakuti tanthauzo lake ndi bwino kugula mfuti wapadera kuti mukufuna kugwiritsa ntchito nozzle - nozzle 1.8 mm m'mimba mwake. The zikuchokera okonzeka akhoza sprayed mu wosanjikiza limodzi ndipo ngati n'koyenera, ndiyeno awiri. Atmospheric kuthamanga pa mfuti akhale zitatu mowa umodzi. Kuthira filimu yaing'ono limapezeka padziko chithovu.

Pamene zikuchokera ndi sprayed, m'pofunika kudikira evaporation wa zosungunulira. nthawi The amadalira zifukwa zambiri monga mpweya kutentha, chiwerengero cha zigawo ntchito ndi mathamangidwe mphepo, ngati kumachitika kunja. Nthawi imene muyenera kuti agwirizane pamalo awiri, sayenera upambana mphindi 3, kuyambira nthawi imeneyi zikuchokera ndi mouma. Kulowa mbali ziwiri ayenera yomweyo zolondola, kuyambira pambuyo zimene zipangizo okonzeka kukonza cholakwa sadzakhala zotheka. Pamaso pa zomatira ntchito kulumikiza a chithovu, m'pofunika kubweretsa kutentha kwa 20 C, kenako kusakaniza bwino. formulations oterowo bwino yosayenera mphasa kasupe ndi mipando upholstered, monga ntchito polumikiza chithovu mitengo, zikatoni ndi nsalu. Kupanga mankhwala otchedwa ndi mipando zomatira thovu, popeza anagwiritsidwa ntchito kwambiri mu makampani.

The zikuchokera zomatira ndi

Kwa nthawi yaitali anali maziko phala butadiene-styrene, polyurethane ndi polychloroprene. Kudzera kutukula luso Ufumuyi kuchepetsa jombo ndi zigawo kuyaka. Pakali pano, zikuchokera latsopano ali wamng'ono kungasokoneze amene amanyamula naye ntchito, komanso owerenga m'tsogolo, ndipo amachititsa mavuto kochepa chilengedwe.

Zomatira thovu kwa ofotokoza madzi odorless ndi otetezeka kusiyana ndi anthu amene solvents ndi alipo zikuchokera. Popeza alibe fungo, omasuka naye ntchito, monga zilibe zimatulutsa poizoni. Ubwino waukulu wa nkhaniyi akuti ndi chitetezo moto. ubwino monga chakuti amadya kuchuluka kochepa wa zopangira cholinga chapamwamba kwambiri.

ntchito zomatira, mukhoza kugwiritsa ntchito burashi kapena mfuti kutsitsi. Mu ntchito zake Tsatiraninso malangizo ndi kutsatira malamulo chitetezo.

Kodi kusankha zomatira apamwamba?

Atapita masiku pamene wapangidwa ndi solvents flammable ndi poizoni, tsopano zambiri vuto lililonse. zigawo zikuluzikulu amadziŵika yomweyo kulumikiza mphamvu ndi zabwino elasticity msoko. Ubwino waukulu zomatira zamakono monga:
- No solvents inflammable;
- dispersibility kwambiri ndi mfuti;
- zofewa ndi kusintha mfundo;
- mkulu zili zotsalira youma.

Main makhalidwe a khalidwe la mankhwala

Kuti pamene afika sitolo si acimbadzoza ndi kuchuluka kwa kusankha, muyenera kudziwa wotani zomatira thovu imatengedwa kuti Mkhalidwe:
- n'kofunika kuti lili ndi kugwirizana kwambiri;
- muyenera kulabadira chakuti zikuchokera izi anatha kumata zidutswa za thovu, osati kwa wina ndi mzake, komanso nsalu, zikopa, nkhuni, polyether CHIKWANGWANI, pulasitiki ndi zitsulo;
- izo sizigwira azinyadira;
- otetezeka pamene ntchito komanso mu ntchito za m'tsogolo;
- M'pofunikanso kuti madzi zosagwira;

zomatira makamaka wabwino

Pali kusiyana izi, amene ntchito mu formulations zomatira ntchito ndi thovu:
- zomatira thovu ayenera mulibe toluene, ndi analogs zake zonse;
- kuthira zikuchokera akhale kwa mphindi zochepa yomata ndipo viscous, kuyambira ndikofunikira kugwira ntchito ndi m'madera ambiri;
- pambuyo kutsegula kwa zinthu chidebe ayenera wokonzeka ntchito, sizikusoweka oyambitsa ndi kunjenjemera.

malamulo chitetezo

Akatswiri amanena kuti ndi bwino kugwiritsa ntchito zikuchokera mfuti kapena kugula kutsitsi zomatira ndi thovu. Ngakhale kuti palibe amene amaletsa kugwiritsa ntchito wodzigudubuza kapena burashi, koma njira imeneyi limodzi ndi mowa kwambiri a zipangizo. The zikuchokera ali pafupifupi palibe fungo, koma ndi bwino ntchito mu chipinda ndi mpweya wabwino, osati kuti poizoni poizoni.

Malamulo ena ayenera kutsata pamaso gluing pamalo angapo:
- poyamba kutsukidwa padziko ku mafuta, fumbi ndi zinyalala;
