Yintoni isikhumba sePu?

Isikhumba se-puse sibizwa ngokuba sisikhumba sasePolyurethane, esilusikhumba owenziwayo esenziwe ngezinto zePolyurethane. Isikhumba sePu sisikhumba esiqhelekileyo, isetyenziswa ngokubanzi kwiimveliso ezahlukeneyo zeshishini, njengengubo, impahla, ifenitshala, impahla yangaphakathi kunye nezinye amashishini.

Ke ngoko, isikhumba sePu sihlala kwindawo ebaluleke kakhulu kwimarike yesikhumba.

Kwinkqubo yemveliso kunye nengcinga yokhuseleko lwendalo, isikhumba sePu sisiseko seentlobo ezimbini zokusetyenziswa kwesikhumba se-PU kunye nesikhumba se-pue.

Nguwuphi umahluko phakathi kweentlobo ezimbini zesikhumba?

Makhe siqwalasele kuqala umahluko kwiinkqubo zabo zemveliso.

Inkqubo yemveliso yesikhumba yemveli ye-PU:

1. Inyathelo lokuqala kwimveliso yesikhumba le-PU kukwenza polyurethane, kunye ne-idolnanate (okanye i-polynanate (okanye i-polyol) kunye nePolyteeter, iPolysist kunye nezinye izinto ezingafunekiyo zenziwa kwi-Polysurethane Repn Repen ngempendulo yekhemikhali.

2. Ukuthintela umhlaba, i-polyurethane idityaniswe kwindawo yesikhumba, njengomphezulu we-puse yesikhumba, i-substrate inokuthi ikhethwe iintlobo ngeentlobo zezixhobo, njengekotoni, ilaphu le-polyester, njl., Okanye ezinye izinto zokwenziwa.

3. Ukulungiswa kunye nonyango, i-sublerate edityanisiweyo iqhubekisiwe kwaye inyangwa, njengokungathobeli, iprint, ukudaya kunye nezinye iinkqubo, umbala kunye nesiphumo esifunekayo. La manyathelo aqhubayo anokwenza isikhumba se-punwa sijongeka ngakumbi njengesikhumba sokwenyani, okanye ube nefuthe lokuyilo oluthile.

I-4. Ukunyanga emva kokugqitywa kokugqitywa, isikhumba se-Pu sinokufuna ukwenza amanyathelo athile onyango, njengokhuseleko lwamanyeko, unyango olungeyo-njl, njl.

5. Ukulawulwa komgangatho kunye nokuvavanywa: kuwo onke amabakala emveliso, ukulawulwa komgangatho kunye nokuhlolwa kuya kwenziwa ukuqinisekisa ukuba isikhumba se-PU sihlangabezana noyilo kunye neemfuno ezichaziweyo.

Inkqubo yemveliso yokuphinda isebenze kwakhona:

1. Qokelela kwaye uphinde uphume kwakhona iimveliso ze-Polyrerthane, ezinjengeemveliso zesikhumba ze-punule, ukuvelisa inkunkuma, emva kokuhlela kunye nokucoca umngcipheko, kwaye emva koko wenze unyango;

2. Philisa i-polyurethane ye-pollytune ecocekileyo kumasuntswana amancinci okanye umgubo;

3. Sebenzisa umxube ukuxuba amasuntswana ePolyurthane okanye i-polders ene-Polypollymers, iifilitha, i-amotiogizers, i-amotioxizers, i-antioxizers, i-antioxizers, njl. Njl. I-Polyururthane Matrix iyokwenziwa kwifilimu okanye imo echaziweyo ngokuphosa, ukuthuthuzela okanye ukwala.

4. Izinto ezenziweyo zishushu, zipholile kwaye ziphiliswe ukuqinisekisa iipropathi zomzimba kunye nokuzinza kwekhemikhali.

5. Ukuthathwa kwesikhumba se-pules, ukuphoxeka, kudityaniswe, ukuthoba kunye nolunye unyango lomphezulu ukuze ufumane inkangeleko oyifunayo kunye nokubeleka;

I-6. Yenza ihlolisiso loMgangatho ukuze ikwazi ukuhlangabezane nemigangatho efanelekileyo kunye neemfuno. Emva koko ngokweemfuno zabathengi, ukusikwa kubalingane obahlukeneyo kunye nemilo yesikhumba esigqityiweyo;

Ngenkqubo yemveliso, inokuqondwa ukuba kuthelekiswa nesikhumba se-pues pues, ukuphinda kusetyenziswe isikhumba se-PU kuhlawula ukhuseleko lwendalo kutshintsho lokukhusela ukusifakelwa kwendalo, ukunciphisa ungcoliseko lwendalo. Sinezatifikethi ze-GRRs ze-PU kunye ne-PVC Leather, exhasa umbono wophuhliso oluzinzileyo kunye nokukhusela okusingqongileyo, kunye nokuziqhelanisa nemveliso yesikhumba.
