O upusii vave ma sili atu, faufautua logoina e fesoasoani ia te oe e filifili le fofo sao e fetaui ma ou manaʻoga uma, o se taimi puupuu o tupulaga, taulima lelei ma tulaga ese oloa ma auaunaga mo le totogiina ma felauaiga mataupu moSaina Ukulele ma High Density Man-Made Wood tau, O le a matou tuʻuina atu mea e sili atu ona lelei i mamanu eseese ma auaunaga faʻapolofesa.Matou te faʻafeiloaʻi ma le faʻamaoni uo mai le lalolagi atoa e asiasi i la matou kamupani ma galulue faʻatasi ma i matou i luga o le faʻavae o taimi umi ma manuia tutusa.

Fa'amatalaga:Tert-butyl acrylate o se vaila'au sili ona taua fa'avae ma mea fa'agata.Ona o lona tulaga tulaga ese ma le malosi o molelaula polar, unsaturated fusiua lua ma carboxylate (-COOR) fausaga, e mafai ona maua mai le tele o ituaiga O loʻo i ai se fua polymer ma lelei faatinoga, ma saunia palasitika, cross-sootai ma isi polymers e ala i emulsion. polymerization, polymerization solution, copolymerization ma isi auala gaosi. E malosi lona faʻapipiʻi polymer, e lelei lona manino, ma manino lona faʻavaeina ata, lea e mafai ai ona tele le gafatia i le fesuiaiga o vailaʻau eseese.O mea fa'amama, alava gaosia, pa'u gaosia, palasitika, pa'u, mea fa'apipi'i, ma isi mea ua fa'aaogaina lautele.

 

Uiga:

Tert-Butyl Acrylate e mafai ona faʻaaogaina e tuʻuina atu mea nei i polymers:

• Vailalo

• Mautu o kemisi

• Feso'ota'i

•Maaa

• Tete'e masi

• pipii

• Maualuluga mautu

•Tagata tau.

 

Talosaga:tert-Butyl Acrylate e fai ai homopolymers ma copolymers.Copolymers o tert-Butyl Acrylate e mafai ona saunia i le acrylic acid ma ona masima, amides ma esters, ma methacrylates, acrylonitrile, maleic acid est rs, vinyl acetate, vinyl chloride, vinylidene chloride, styrene, butadiene, polyesters unsaturated ma suauʻu faʻamago, ma isi. tert-Butyl Acrylate ose mea'ai aoga tele mo le fa'aogaina o vaila'au, aua e faigofie ona o'o i le tele o mea fa'aola ma mea fa'aletino.

 

Fa'amatalaga lautele:O faʻamaumauga o loʻo i totonu o lenei faʻasalalauga e faʻavae i luga o lo tatou poto ma le poto masani i le taimi nei. I le vaʻai atu i le tele o mea e ono aʻafia ai le gaosiga ma le faʻaogaina o a tatou oloa, o nei faʻamaumauga e le faʻamalo ai le gaosiga mai le faia o a latou lava suʻesuʻega ma suʻega, e le o nei faʻamaumauga. fa'aalia so'o se fa'amaoniga o nisi meatotino, po'o le talafeagai o le oloa mo se fa'amoemoega fa'apitoa.So'o se fa'amatalaga, ata, ata, fa'amaumauga, fua, mamafa ma isi. o lo'o tu'uina atu i inei e mafai ona suia e aunoa ma ni fa'amatalaga muamua ma e le fa'atatau i le tulaga lelei fa'akonekarate o le oloa.O le matafaioi a le tagata e mauaina a tatou oloa e fa'amautinoa o lo'o tausisia so'o se aia tatau ma tulafono ma tulafono o iai.

 

 

afifi:170kg mamafa mama, poʻo pe a manaʻomia.

 

Felauaiga ma le teuina:

Aloese mai timuga susulu ma le maualuga o le vevela i felauaiga, Ina ia puipuia le polymerization, tert-Butyl Acrylate e tatau ona teuina i taimi uma i lalo o le ea, ma ia aua lava neʻi i lalo o kasa inert.O le iai o le okesene e mana'omia mo le fa'amautu e galue lelei.E tatau ona iai se mea fa'amautu ma le vevela e teu ai e le tatau ona sili atu i le 35 °C.I lalo o nei tulaga, e mafai ona faʻamoemoeina le tumau o le teuina o le tausaga e tasi.Ina ia faʻaitiitia le ono ova le teuina, e tatau ona mulimulitaʻi le faiga o le teuina o le "muamua-i-muamua-i fafo" mataupu faavae.Mo taimi umi e teu ai i luga o le 4 vaiaso e fautuaina e toe faʻatumu le okesene ua malepe. O tane teu ma paipa e tatau ona faia i le uʻamea poʻo le alumini. E tatau ona mataʻituina tulafono faʻatonutonu mo le teuina o vai mumu (mea faʻaeletise-faʻaleagaina, tane faʻafefe ma e pu'e afi ma isi mea). O tane teu, pamu ma paipa e tatau ona fa'aeleele.

O upusii vave ma sili atu, faufautua logoina e fesoasoani ia te oe e filifili le tali saʻo e fetaui ma ou manaʻoga uma, o se taimi puupuu o tupulaga, faʻatauga lelei ma oloa ma auaunaga tulaga ese mo le totogiina ma le felauaiga o fefaʻatauaʻiga mo le Good Quality Wholesale 21″/23″/26″ Solid Koa Top Ukulele (AU50-TBA-3), Matou te fa'amoemoe e fa'atuina le tele o fa'alapotopotoga fa'alapotopotoga ma tagata fa'atau i le lalolagi atoa.
Lelei LeleiSaina Ukulele ma High Density Man-Made Wood tau, O le a matou tuʻuina atu mea e sili atu ona lelei i mamanu eseese ma auaunaga faʻapolofesa.Matou te faʻafeiloaʻi ma le faʻamaoni uo mai le lalolagi atoa e asiasi i la matou kamupani ma galulue faʻatasi ma i matou i luga o le faʻavae o taimi umi ma manuia tutusa.
