Chiyero chePolyol neisocyanate:

Polyol ine hydroxyl yakawanda uye ine huremu hwakawanda, izvo zvichawedzera crosslinking density uye zvinobatsira kuvandudza foam density. Kugadzirisa isocyanate index, kureva, molar ratio yeisocyanate kune active hydrogen mupolyol, kuchawedzera mwero wecrosslinking uye kuwedzera density. Kazhinji, isocyanate index iri pakati pe1.0-1.2.

 

Kusarudzwa uye chiyero chemushonga wefuro:

Rudzi uye chiyero chemushonga unopupuma zvinokanganisa zvakananga mwero wekuwedzera kwemhepo uye huwandu hwemabubble mushure mekupupuma, uye zvinokanganisa ukobvu hweganda. Kuderedza chiyero chemushonga unopupuma kunogona kuderedza kuvhurika kwefuro uye kuwedzera huwandu. Semuenzaniso, mvura, semushonga unopupuma wemakemikari, inosangana neisocyanate kuti igadzire kabhoni dioxide. Kuwedzera huwandu hwemvura kunoderedza huwandu hwefuro, uye huwandu hwayo hwekuwedzera hunofanira kudzorwa zvakanyanya.

 

Huwandu hwechinokonzeresa:

Chinokonzeresa furo chinofanira kuve nechokwadi chekuti kuumbwa kwefuro uye kuumbwa kwejeli zvinosvika pakuenzana kwakasimba, zvikasadaro kudonha kwebubble kana kupwanyika kuchaitika. Nekubatanidza compound ine alkaline tertiary amine ine simba guru rekugadzirisa furo uye simba guru rekugadzirisa furo, chinokonzeresa chakakodzera system yekuzvigadzira ganda chinogona kuwanikwa.

 

Kudzora tembiricha:

Kupisa kwechikobvu: Ukobvu hweganda huchawedzera sezvo tembiricha yechikobvu ichidzikira. Kuwedzera tembiricha yechikobvu kuchakurumidzisa reaction rate, izvo zvinobatsira kugadzira chimiro chakasimba, nokudaro zvichiwedzera density, asi tembiricha yakakwira inogona kukonzera reaction yacho kuti isadzorerwe. Kazhinji, tembiricha yechikobvu inodzorwa pa40-80℃.

 

Kupisa kwekuibva:

Kudzora tembiricha yekukwegura kusvika pa30-60℃ uye nguva kusvika pa30s-7min kunogona kuwana chiyero chakakodzera pakati pesimba rekubvisa uye kushanda zvakanaka kwekugadzira kwechigadzirwa.

 

Kudzora kumanikidzwa:

Kuwedzera kumanikidzwa panguva yekuburitsa furo kunogona kudzivirira kukura kwemabubbles, kuita kuti chimiro chefuro chive chidiki, uye kuwedzera huwandu hwezvinhu. Zvisinei, kumanikidzwa kwakanyanya kuchawedzera zvinodiwa zvefuro uye kuchawedzera mutengo.

 

Kumhanya kwekukurunga:

Kuwedzera kumhanya kwekukurunga nemazvo kunogona kuita kuti zvinhu zvakabikwa zvisanganiswe zvakaenzana, zviite zvizere, uye zvibatsire kuwedzera huwandu hwemhepo. Zvisinei, kumhanya kwekukurunga nekukurumidza kuchaunza mhepo yakawandisa, zvichikonzera kudzikira kwehuwandu hwemhepo, uye kazhinji kunodzorwa pa1000-5000 rpm.

 

Kuzadza zvakanyanya:

Huwandu hwemusanganiswa wemusanganiswa wemusanganiswa wemushonga wekuzvigadzira wega hunofanira kunge hwakakura kupfuura huwandu hwemusanganiswa wemushonga wefree furo. Zvichienderana nezvigadzirwa uye sisitimu yezvinhu, huwandu hwekuzadza hunowanzova 50%-100% kuti hurambe huine kumanikidzwa kwakanyanya kwemould, izvo zvinoita kuti furo rinyungudike muganda.

 

Nguva yekuyera ganda:

Mushure mekunge furo repolyurethane radururwa mumodhi, kureba kwenzvimbo yacho, ndiko kukura kweganda. Kudzora nguva yekuyera mushure mekudurura inzira imwe yekudzora ukobvu hweganda.
