Guruu nokuti furo raro chikuru unhu

The kutaurwa furo rabha wokutanga vakanyorwa muGermany muna 1941, apo akagamuchira kwetsaona inopupuma polyurethane. Mupfungwa yokufananidzira, kuti furo - pfuma ine porous marongerwo izere mhepo. Yezvinoreva ichi acho rakafara zvakakwana, izvozvo anongokurukurwa zvakanaka compression nokuda kwayo elasticity, ane rakaisvonaka breathability uye akachengeta yaro yepakutanga chimiro. Most inowanzoshandiswa nokuda fenicha, zvemitambo nhumbi, motokari nezvigaro, kuputira zvinhu uye matoyi nyoro. Uyewo muupenyu hwezuva nezuva ane muuzhinji chikumbiro chacho kubudisa-siyana pendi rollers, sechipanji, dhishi kugeza uye kuchenesa. MuEurope, mashoko aya anoendeswa kushandiswa senzvimbo kavha chigadzirwa.

kushandisa guruu

kuti foam kuti namira iri nokuita kushandisa. Nokuti kushandisirwa zvakanaka kutenga pfuti chaiyo kuti unoda kushandisa kamwene - kamwene 1.8 mm mu dhayamita. The wakagadzirira sezvamunoita kunogona sprayed mune rimwe rukoko uye, kana zvakakodzera, uye ipapo maviri. Atmospheric kumanikidzwa panguva pfuti kunofanira kubva matatu kusvika matanhatu nomuzariro. Pashure kushandisa chiduku firimu anozviratidza pamusoro pechiso furo.

Kana murwiyo iri sprayed, zvakakodzera kumirira kwemvura kuti solvent. Nguva kungaenderana zvinhu zvakawanda zvakadai mhepo tembiricha, uwandu rakaiswa akaturikidzana uye mhepo velocity, kana kunoitika kunze. Nguva iyo vanofanira kubatana hukawanika maviri, haafaniri kupfuudza maminitsi 3, sezvo panguva iyi murwiyo ndiyo yaoma. Kubatana migove miviri vanofanira pakarepo kwakarurama, sezvo pashure maitiro akagadzirira zvinhu kururamisa kukanganisa haangavi zvinobvira. ari namira asati paakakumbira chokuedza pamusoro furo, zvakakodzera kuunza tembiricha 20 C, uye ipapo kusanganisa zvakanaka. Formulations vakadaro unonyatsokodzera chitubu nemamatiresi uye upholstered fenicha, sezvo inoshandiswa unobva furo kuti huni, makadhibhokisi uye Textiles. In pagadzirwe imwe pfuma yainzi fenicha namira furo, nokuti zvikuru inowanzoshandiswa indasitiri.

The Kuronga namira

Kwenguva refu yaiva nheyo namatidza butadiene-styrene, polyurethane uye polychloroprene. Kuburikidza kukura zvemichina afunga kuti kuderedza rabha uye combustible zvinoriumba. Pari, murwiyo itsva ine muduku inokanganisa avo anotakura naye basa, uyewo vanoshandisa mune ramangwana, uye chinoita usingashandi kukuvadza zvakatipoteredza.

Guruu furo nokuti odorless mvura-inobva ndiyo zvikuru tichienzanisa avo umo zvokufembedzwa varipo vari murwiyo. Sezvo asina kunhuwidza, akasununguka kushanda naye, sezvo risingabereki emit muchetura. The chikuru mukana iyi anoonekwa kuti moto kwakachengeteka. Zvazvakanakira dzinosanganisira chokwadi unopedza usingashandi kwazvo mbishi zvinhu kusvika pakupedzisira chinangwa.

Guruu chikumbiro, unogona kushandisa bhurasho kana pfapfaidzo pfuti. In kushandisirwa kuva nechokwadi kutevera mirayiridzo vanoomerera yakachengeteka mitemo.

Sei kusarudza yepamusoro namira?

Gone mazuva kana rinoumbwa zvinobata moto uye chepfu zvokufembedzwa, ivo hwawedzera isingakuvadzi. Kwakadaro zvinoriumba Munokudzwa nguva imwe Muitiro unobatanidza simba uye yakanaka elasticity musono. The chikuru zvakanakira adhesives ano dzinosanganisira:
- No inflammable zvokufembedzwa;
- dispersibility chakanakisisa ane pfuti;
- nyoro uye kusanduka majoini;
- mukuru zviri pakaoma vakasara.

Unhu Zvikuru chatingatevedzera chigadzirwa

To pashure kuuya kuchitoro haisi kuzorwa nokuwanda rwokusarudza, unofanira kuziva kuti namira furo mhando anoonekwa kuti Qualitative:
- zvakakosha kuti inopa simba kubatana;
- unofanira kuteerera chokwadi kuti sezvamunoita izvozvi akakwanisa micheto yekapepa katsva aka zvidimbu furo, kwete chete kune mumwe, uyewo jira, dehwe, huni, polyether faibha, mapurasitiki uye simbi;
- hazvizorevi vesa;
- njodzi kana aishanda pamwe mukushandisa ramangwana;
- Zvinokoshawo kuti kuva mvura nemishonga;
- pakupera achaita Usazviomesera rwakashodoka.

Zvikurukuru zvakanaka namira

Pane zvinotevera kusawirirana, izvo zvinoshandiswa namira Formulations kushanda furo:
- namira furo haafaniri dzine toluene, uye zvose analogs yayo;
- pashure kushandisa murwiyo kunofanira kwemaminitsi mashoma kuti namuka uye viscous, sezvo zvakafanira kushanda munzvimbo huru;
- pashure Panovhurwa mugaba zvinhu unofanira akanyatsogadzirira kushandiswa, hakufaniri ruchiparira uye kudedera.

chengetedzo mitemo

Nyanzvi dzinoti zvakanaka kushandisa Zvinoumba pfuti kana kutenga namira pfapfaidzo kuti furo. Kunyange zvazvo pasina munhu unorambidza kushandiswa chinotenderera kana mumakwenzi, asi nzira iyi pamwe chinokosha kudyiwa mbishi zvinhu. The sezvamunoita ane anenge asina kunhuwidza, asi zvakanakisisa kurishandisa muimba pamwe kufefetedza zvakanaka, kwete kuti muchetura muchetura.

Vamwe mitemo inofanira kutevedzerwa asati gluing akawanda hukawanika:
- pakutanga vakachenesa pose kubva girisi, huruva uye tsvina;
- namira furo rinofanira kuva mutete uye kumirira kuti ipfungaire solvent vapor;
- kana paine yaitsigira divi chikumbiro, murwiyo akafuka vanachandagwinyira penyika;
- ose nzira anofanirawo hazvo anoitisa chete panguva mukamuri tembiricha. Zvikasadaro, kuti guruu anogona thicken uye vanorasikirwa ose zvivako zvayo, izvo pakupedzisira vane chikuru nezvainoita rakapera chigadzirwa.
