I-1,4-i-Butadiediolcas110-63-4: Umdlali oguquguqukayo kwishishini lekhemikhali, ukushenxisa kwi-boom entsha yezicelo ezahlukeneyo

Kutshanje, i-1,4-i-butanediol (i-BDO) iye yaba sisihloko esishushu kwicandelo lekhemicali. Njengesixhobo esibalulekileyo sekhemikhali, silithululelo ngamashishini amatsha kumashishini amaninzi anoluhlu lwayo lwezicelo, uqhuba uphuhliso olunamandla lomsebenzi wemizi-mveliso.

Kwimigca yemveliso yeemveliso zePolyester, i-1,4-butadiol ibonisa ixabiso elingaphantsi. I-synthesis ye-Polybutlene Terephthalate (PBT) ixhomekeke kakhulu kuyo. I-PBT, njengePhepha lePhepha lePhepha lePhepha lePhepha lePhepha lePhepha lePhepha lePhepha lePhepha lePhepha lePhepha lePhepha lePhepha lePhepha le-Polyster, lineempawu ezibalaseleyo zoomatshini, ukuxhathisa ngamachiza okuqina kwamachiza, kunye nokuzinza kombane okuphezulu kunye nokuzinza kombane. Okwangoku, ishishini le-elektroniki kunye neshishini lombane liyanda ngokukhawuleza, kunye nezinto ezahlukeneyo zekhaya kunye nokuchaneka kwe-elektroniki ezivela ngokuqhubekayo. Izindlu zokusebenza zombane kunye neziqhobosiweyo ezenziwe ngezinto ze-PBT azikukuqinisekisi ukhuseleko kunye nokuzinza kwezixhobo kodwa zinokubona iimveliso ezinembonakalo eqhubekayo, ekhokelela kwimfuno yokunyuka kwentengiso. Ishishini lokwenza inqwelo-mafutha likwabonisa ukhetho olukhulu lwe-PBT. Iinxalenye ezinje ngemoto yemoto kunye nezihloko ezenziwe nge-PBT zinokumela ukhukuliseko lweemeko zendlela ngelixa kuphuculwa ukwenziwa kwesithuthi.

Kuworkshop lwemveliso ye-thermoplastic polyurethane (i-TPU), i-1,4-i-butaidiol ikwayilungu eliphambili ". I-TPU idibanisa irabha ephezulu yerabha ngenkqubo elula yeplastiki, kwaye iimveliso zayo ezigqityiweyo zinxiba, zichasene neoyile, kunye nokunganyangeki. Ukusuka kwiZihlangu zemidlalo zemihla ngemihla, ezibonelela ngenkxaso yentshukumo yezemidlalo, kwimibhobho, ucingo oluqhelekileyo, iqinisekisa ukhuseleko olusebenzayo, kwaye sisiseko sokusebenza esibekwe yi-1,4-i-butadiol esenzayo kunokwenzeka.

I-inki, i-inki, kunye nokuprinta kunye nemizi-mveliso yokudaya imizi-mveliso iphinde yenziwa njengotshintsho olutsha enkosi kwi-1,4-butadiol. I-γ-butyrolactone iveliswe kuyo inendawo ebilayo ephezulu kunye nokungagungqi okugqwesileyo, ukukwazi ukunyibilika ngokulula, i-onemers yomelele ngakumbi, i-Deye icoceke ngakumbi, igalelo ekuphuculeni ishishini lemichiza lemichiza. Ngapha koko, njengezinto zokuqala ze-synthesies yeziqholo kunye nezithintelo eziphakathi, i-γ-byyrolactone ivula ngokungena kumnyango omtsha wophando kunye nophuhliso lweemveliso ezihle, kwaye kulindeleke ukuba isuswe kwintengiso.

Phantsi kwendawo yokuqalisa ye-Lithimu ye-Lithium, i-N-Methyylpylpylidone (NMP), i-1,4-butanediol, itsalele ingqalelo kakhulu. Njenge-soltic ye-berotic ye-berotic, i-NMM iyoyisile le ngxaki yokuluka kwe-lithium zebhetri yeLithium ye-LOHTRODE, iququzelela ukudityaniswa kwe-bibors kunye nezinto ezisebenzayo. Ligorha elingangcungqelelwanga emva kokuphuculwa kwentsebenzo kunye nomgangatho weebhetri ze-lithium, ixhasa ngamandla iMileage entsha yamashishini anje ngezithuthi ezitsha zamandla kunye nezixhobo zokugcina amandla.

Kumda wefashoni kunye ne-tetrarahydrofura (i-TIF) ye-1,4-i-Butyiediol iguqulwe ngakumbi ibe yi-polytetrafura (i-ptmeg), eye yaba sisixhobo se-Polytex. Oku kwenza ukuba ifashoni yezemidlalo kunye nefashoni yokuphela kwenqanaba eliphezulu ihambelana ne-curves yomzimba womntu, ukudibanisa intuthuzelo kunye nefashoni, kunye neendwangu zefashoni, kunye nokuguquguquka kweendwangu.

Kwicandelo lophando lwamayeza kunye nophuhliso, i-1,4-butadiol ngokuthe cwaka '. Njengesitshixo sexesha eliphambili eliphakathi, lithatha inxaxheba kumanyathelo eSynthesis entsonkothileyo kunye neziyobisi ze-steroid kunye neentsholongwane. Ifana neebhloko zokwakha ezibuthathaka yokwakha i-molecular eyakhayo, inceda abaphengululi bakhupha izakhiwo ezisebenzayo zeziyobisi kwaye zibonelela ngemibhobho yokohluli izifo ezinzima.

Ngokuphuculwa okuqhubekayo kwetekhnoloji kunye nokuhlola okunzulu kwemfuno yentengiso, ishishini le-1,4-eleadiol kulindeleke ukuba liqhubeke lisandisa, kunye nemizi mveliso ekhulayo, ukubhala isahluko esitsha esikhulu kwimveliso yekhemikhali.
