I-1,4-Butanediolcas110-63-4: Isidlali esiguquguqukayo embonini yamakhemikhali, efaka i-boom entsha yezinhlelo zokusebenza ezahlukahlukene

Muva nje, i-1,4-butanediol (BDO) isiphenduke isihloko esishisayo emkhakheni wamakhemikhali. Njengento ebalulekile ye-organic yamakhemikhali eluhlaza, ijova ubungqabavu obusha kwizimboni eziningi ezinobubanzi bawo bezicelo, ukushayela ukuthuthukiswa okunamandla kweketanga elikhulu lezimboni.

Emigqeni yokukhiqiza yemikhiqizo ye-polyester, i-1,4-butanediol ikhombisa inani elingenakufinyeleleka. Ukuhlanganiswa kwePolybutylene Terephthalate (PBT) kuncike kakhulu kukho. I-PBT, njenge-Thermoplastic Polyester Engineering Plastic, inezakhiwo ezivelele zemishini, ukumelana okuqinile kokugqwala kwamakhemikhali, kanye nokufakwa okuhle kukagesi nokuqina kobukhulu. Njengamanje, imboni ye-elekthronikhi kanye ne-gesi ye-Appleinancection iyanda ngokushesha, inemishini ehlukahlukene yasekhaya futhi amadivaysi e-elekthronikhi aqhamuka ngokuqhubekayo. Izindlu ze-Applical zikagesi ezenziwe ngezinto ezisebenza ngogesi nezinto ezenziwe ngezinto ze-PBT akuqiniseki nje kuphela ukuphepha nokuqina kwemishini kodwa futhi kuvuselela imikhiqizo ngokubukeka okujabulisayo nokuhlala isikhathi eside, okuholela ekufuneni kwemakethe okukhulayo. Umkhakha wokukhiqiza izimoto futhi ukhombisa ukukhetha okuhle kwe-PBT. Izingxenye ezinjengezibangeli zeminyango yemoto nama-bumpers ezenziwe nge-pbt angamelana nokuguguleka kwezimo ezinzima zomgwaqo ngenkathi ethuthukisa ukwenziwa kwemoto.

Emihlanganweni yokusebenzela yokukhiqiza ye-Thermoplastic Polyurethane (TPU), i-1,4-butanediol nayo iyilungu eliyisisekelo ". I-TPU ihlanganisa ukuqina okuphezulu kwenjoloba ngokusebenza okulula kwepulasitiki, futhi imikhiqizo yayo eqediwe iyagunda, imelana namafutha, futhi imelana nokubanda. Ukusuka ezisoleni zezicathulo zemidlalo yansuku zonke, ezinikeza ukwesekwa okunethezekile futhi okuhlala isikhathi eside kwabathandi bezemidlalo, kumapayipi, ama-wire kanye namakhebula okuhambisa izimboni, bese kuthi ukuphepha okuphezulu kwe-Industrial Converios, i-TPU ihamba nge-umpiquitor, futhi yisisekelo sokusebenza esibekwe yi-1,4-butanediol kwenza sikwazi.

I-coating, inki, kanye nezimboni zokuphrinta nokudaya ziye zabhekana nezinguquko ezintsha muva nje ngenxa eyi-1,4-butanediol. I-γ-burrolactone ekhiqizwa kusuka kuyo inendawo ebilayo ephezulu ne-solubility enhle kakhulu, ekwazi ukuqeda kalula amakhompiyutha ahlukahlukene ahlukahlukene nama-polymer, ukunamathela okucacile okucacile, kanye namaphethini okushicilelwa okucacile, kanye namaphethini okucaca okucacile, okusobala okucacile, okubangela ukuthuthukiswa komkhakha wamakhemikhali wendabuko. Ngaphezu kwalokho, njengokuqala kokuqala kokuhlanganiswa kwezinongo kanye namakhambi amakhambi, i-γ-burrolactone kuvulelisa umnyango omusha ocwaningweni kanye nokuthuthukiswa kwamakhemikhali amahle, futhi kulindeleke ukuthi kuvulwe imikhiqizo emihle kakhulu okufanele yethulwe emakethe.

Ngaphansi kwegagasi elikhulayo lemboni yebhethri le-lithium, i-NPSylpyrOne (NMP), okususelwa ku-1,4-butanediol, kudonsele ukunakwa okuningi. Njenge-solvent ye-polar aprotic, i-NMP iye yanqoba inkinga ye-solubility empofu ye-lithium bettery electrode ye-electrode ye-lithium, lula ukuxutshwa komfaniswano wama-binders nezinto ezisebenzayo. Yiqhawe le-unsung ngemuva kokuthuthuka kokusebenza kanye nekhwalithi yamabhethri e-lithium, asekela ngokuqinile mileage entsha yezimboni ezinjengezimoto ezintsha zamandla namadivayisi wokugcina amandla.

Emgqeni wemfashini nezindwangu, i-tetrahydroforan (thf) eyenziwe ngokubamba iqhaza kwe-1,4-butanediol iguqulwe iguqulwe ibe yi-polytetrahydroforunan (PTmeg), iba yinto eluhlaza ye-spandex fibers nakuma-polyurethane lastomers. Lokhu kwenza imfashini yezemidlalo kanye ne-high-end ngaphezulu ivumelane namajika omzimba womuntu, ukuhlanganisa umqondo wedudulo nomqondo wemfashini, kanye nezindwangu ezinikeza amandla aphezulu.

Emkhakheni wocwaningo kanye nentuthuko yezemithi, i-1,4-butanediol buthule isebenza njenge- "nonsung hero". Njengomphakathi osemqoka wezemithi, ibamba iqhaza ezitebhisini zokuhlanganiswa eziyinkimbinkimbi zezidakamizwa ezithile kanye nama-antibiotics. Kufana namabhulokhi wokwakha abucayi wokwakha isakhiwo samangqamuzana, asiza abacwaningi ukuba bakhiphe izinhlaka zezidakamizwa ezisebenzayo futhi banikeze izinhlamvu zokunqoba izifo ezinzima.

Ngokuthuthuka okuqhubekayo kobuchwepheshe kanye nokuhlolwa okujulile kokufunwa kwemakethe, imboni ye-1,4-butanediol kulindeleke ukuthi iqhubeke yandise, ngezimboni ezikhuphukayo nezisezansi zisebenzisana ezisebenzisana nakwizinkundla ezintsha ezifufusa embonini yamakhemikhali.
