Kushandiswa
1,4-butandediol (bdo)Icho chakakosha organic makemikari zvigadzirwa zvine huwandu hwakawanda hwekushandisa. Nzira huru yekushandisa iri seinotevera:
Kugadzirwa kwePolyester Chigadzirwa
- Yeiyo synthesis yePolybutylene terephthalate (PBT): PBT ndeyekunyanyisa Thermoplastic polyster engineering mapurasitiki. Iyo ine yakanaka michina yezvivakwa, yakanaka yemakemikari corrosion kupesana, magetsi makuru magetsi, uye kusimba kwakasimba kugadzikana. Iyo inoshandiswa zvakanyanya mumagetsi uye magetsi emidziyo yemidziyo yekugadzira yakasiyana-siyana yemagetsi ekugadzira uye anobatana. Zvimwe zvikamu muindasitiri yemotokari, senge mwero wemotokari zvinobata uye bumpers, zvakare inowanzogadzirwa uchishandisa PBT zvigadzirwa.
- Zvekugadzirwa kweTernMplastic Polyurethane (TPU): TPU inosanganisa yakakura yekukora kweRabha neiyo nyore kuita kwepurasitiki. Iyo inopfekedza, inodzivirira mafuta-mafuta, uye inotonhora-inopesana. Izvo zvinowanzoshandiswa kugadzira shangu zviga, mapaipi, waya uye tambo yemabhandi, etcums of conveyor
Kugadzira kwe γ-butyrolactone uye n-methylpyrrolidone (NMP)
- γ-butyrolactone: Iyo yakanakisa-point-point-point solvent ine yakasimba solubility, ine yakanaka yekunyungudusa inokanganisa pane akawanda organic makomputa uye mapolymers. Iyo inoshandiswa zvakanyanya mukubatanidza, ink, uye inodhinda uye maindasitiri ekudyara. Izvo zvakare zvinhu zvekutanga zveSynthesis yezvirevo zvakasiyana-siyana uye mishonga yemishonga, kubva kune dzakasiyana makemikari akanaka ane zvimiro zvakakosha uye mabasa anogona kuzotevera.
- N-methylpyrrolidone: Iyo polar aprotic solvent, kuratidza kugona kwakanyanya kwenyama kune akawanda asina kujairika organic, Inorganic, uye polymer zvinhu. Zvinotonyanya kukosha mukugadzirwa kwemabhatiri eLithium, ainyungudutswa, Electrode anoshanda zvinhu, etc. Izvo zvakare zvine maitiro akakosha mukugadzirwa kweropa, kuchenesa zvemagetsi, uye kuongororwa uye kupatsanurwa uye kupatsanurwa maitiro.
Yeiyo synthesis yeTetrahydrofuran (thf): Tetrahydrofuran yakashandiswa solvent solvent, kuva neyakajairika solubility yemazhinji echisikigo uye synthetic organic makomputa. Mune organic synthesis laboratories uye maitiro ekugadzira emakemikari kugadzirwa, inowanzoshandiswa seyakagadziriswa kusimudzira maitiro. Mukuwedzera, iyo zvakare iyo manyoreredzo yeiyo synthesis yePolytetrydrofuran (ptmeg). Ptmeg inoshandiswa kugadzira spandex fils uye polyurethane elastomers, inopa yakanyanya elastic hwaro hwechinyorwa, yakakwira-yekupedzisira mitambo, uye mamwe maindasitiri.
Zvishandiso mumunda wezvokurapa: Semuenzaniso, mumatanho eSynthesis evamwe mishonga inodhaka uye mishonga inorwisa mabhakitiriya, basa rayo remakemikari rinoshandiswa kuvaka nekugadzirisa zvimisikidzo zvemabolyudhi anodhaka, achifambisa kutsvagurudza, kukura, uye kugadzirwa kwemishonga mitsva.
Kurongedza uye kutumira
25kg / chigubhu kana seyavo zvinodiwa nevatengi.
Ndezvimwe zvinhu zvakajairika uye zvinogona kuburitsa negungwa uye mhepo
Chengetedza nekuchengetedza
HEREF Hupenyu: Mwedzi wemakumi maviri nemana kubva pazuva rekugadzira mukutanga kwekusarongeka kwekuchengetwa munzvimbo inotonhorera yakaoma yezuva, mvura.
Wantiallated Warehouse, kupisa kwakadzika kuoma, kuparadzaniswa kubva ku odifrilan, acids.
