Lapho ukhetha emhlabeni wamakhemikhali, ukuqonda ukwakheka kwamangqamuzana kwento ngayinye kuyisihluthulelo sokuvula izinhlelo zayo ezingaba khona.I-Tri-isobityl phosphate(Tibp) kungenye yamakhemikhali enjalo ethambekele ezimbonini ezahlukahlukene, ezivela kwezolimo kuya kwezamandla. Kulesi sihloko, sizohlola ukwakheka okunemininingwane yamakhemikhali ye-TIBP, sikhanyisela ezakhiweni zalo ezihlukile, nokuthi lolu lwazi lungasiza kanjani ukwandisa ukusetshenziswa kwalo kuzicelo ezahlukahlukene.

Yini i-tri-isobityl phosphate?

I-Tri-isobityl phosphate, ngefomula yamakhemikhali (c4h9o) 3po, i-organic phosphate ester evame ukusetshenziswa njengepulasitiki, ilangabi imbuyiselo, futhi i-solvent ezinqumweni eziningana zezimboni. Kuyinto uketshezi olungenamibala, olunamafutha olungaguquki futhi oluncibilikayo ku-organic solvents, okwenza kube yindawo eguquguqukayo kuzo zombili izilungiselelo zezimboni nezocwaningo.

Ukudicilela phansi isakhiwo samangqamuzana

Umgogodla wokuguquguquka kwe-Tibp ulele esakhiweni sayo samakhemikhali. I-Tri-isobityl phosphate inamaqembu amathathu we-isobityl (C4H9) anamathiselwe eqenjini eliphakathi nendawo (PO4). Lokhu kuhlelwa kwamamolekyur kunikeza uhla lwezakhiwo zamakhemikhali ezibalulekile ukuze ziqonde ukuthi i-tibp iziphatha kanjani ezindaweni ezihlukile.

Amaqembu we-Isobutyl (amaketanga we-Alkyl (ahlanganisiwe we-Alkyl) ahlinzeke nge-tibp ngezimpawu ze-hydrophobic, aqinisekise ukuthi ayikhohlisi emanzini kodwa incibilika kakhulu ezinhlafunweni ze-organic. Iqembu le-phosphate, ngakolunye uhlangothi, linikeza i-tibp imvume yalo yokuvuselela kanye nesimo se-polar, ukuvumela ukuthi ihlanganyele nezindawo ezahlukahlukene ngezindlela ezihlukile. Le nhlanganisela yezakhi ze-hydrophobic ne-polar yenza i-tibp i-solvent enhle kakhulu yezinhlelo zokusebenza eziningi, ikakhulukazi izimboni zamakhemikhali nezokwakha.

Izici ezibalulekile ze-Tri-isobityl phosphate

Ukuqonda ukwakheka kwamakhemikhali kwe-tibp kubalulekile ukuze ukwazisa izakhiwo zayo ezihlukile. Nazi ezinye zezimpawu ezibalulekile ezichaza iTibp:

1.Umphumela weplastiki: Ngenxa yokuguquguquka kwesakhiwo sayo samangqamuzana, i-Tibp iyipulasitiki ephumelelayo, okwenza kube yikhetho elithandwayo ekukhiqizweni kwamapulasitiki, ikakhulukazi i-polyvinyl chloride (PVC). Amaqembu e-Ester avumela i-Tibp ukuthi ithambe izinto zepulasitiki, ithuthukise ukusebenziseka kwayo nokuqina kwazo.

2.I-Flame Retardant: Ukwakheka kwamakhemikhali weTibp kuyasiza ukuthi kube yilapho kubuyiselwa njengelangabi lokubuyiselwa kwelanga ngezinto ezahlukahlukene, ikakhulukazi ezimbonini zezimoto nezogesi. Iqembu le-phosphate esakhiweni linomthelela emandleni e-tibp lokucindezela ukuhlanganiswa nokudla okulibalayo.

3.I-solubity kanye ukuhambisana: I-solubity ye-tibp ku-organic solvents yenza kube luhambisane nohla lwamanye amakhemikhali. Lokhu kubaluleke kakhulu ekwakhiweni kwamapende, ukumboza, kanye nama-adhesives, lapho i-tibp ingasiza ekuthuthukiseni izakhiwo zohlelo lokusebenza zale mikhiqizo.

4.Qinisa: I-Tri-isobityl phosphate yaziwa ngokuqina kwayo kwamakhemikhali, okwenza kube lula ukusetshenziswa ezindaweni ezahlukahlukene zokusebenza okuphezulu. Akuhlali kalula ngaphansi kwezimo ezijwayelekile, ezibalulekile kuzinhlelo zokusebenza lapho kudingeka khona ukusebenza kwesikhathi eside.

Izicelo zangempela zomhlaba zeTibp

Isakhiwo se-molecular sikaTibp sinikeze amandla ukuba isithako esibalulekile ezisetshenziselwa eziningi zezimboni. Isibonelo esisodwa esiphawuleka sisemboni yenuzi, lapho isetshenziswa khona njenge-solvent ekukhishweni kwe-uranium. Ukuzinikela kwalo okuphezulu kuma-organic solvents kanye nokuqina emazingeni okushisa aphakeme kwenza kube ngumuntu ofanelekile ngalezi zinqubo ezifunwayo.

Ekwenziweni kwezinto zokwakha ipulasitiki, i-Tibp ivame ukuqashwa ukuthuthukisa ukuguquguquka nokuqina kwama-polymers. Iphinde yathola ukusetshenziswa uketshezi lwe-hydraulic, ama-lubrantants, kanye nezimbobo, lapho izakhiwo zalo zelangabi zisiza ukuthuthukisa ukuphepha nokusebenza komkhiqizo wokugcina.

Isifundo secala: I-Tibp in Flame Retardant Application

Ucwaningo lwecala olwenziwe yiNyuvesi yaseCalifornia's Fire Research Center luqokomise ukusebenza ngempumelelo kweTibp njenge-Flame Retardant kuma-Polymer Composites. Ucwaningo luthole ukuthi ukufaka i-TIBP kube yizinto ezihlanganisiwe kakhulu kunciphise ngokuvutha kwezinto ngaphandle kokuyekethisa izakhiwo zazo zemishini. Lokhu kwenza i-tibp ibe yinsiza ebalulekile ekukhiqizeni imikhiqizo ephephile, ehlala isikhathi eside yezimboni ezinjenge-aerospace, izimoto, nokwakha.

Ukuvula amandla e-tibp

Isakhiwo sikaMoleksate sikaTri-isobityl phosphate sinikeza inhlanganisela yezimpawu ze-hydrophobic ne-polar ezenza kube ngamakhemikhali abalulekile ezicelo eziningi. Ipulasitiki yayo, ilangabi - i-retardant, futhi izakhiwo ze-solvent zibucayi emasimini asukela ekwakheni ukucubungulwa kwenuzi.

At UZhangjiagang Fortune Chemical Co, Ltd., Sisebenza ngokukhethekile ekuhlinzekeni amakhemikhali asezingeni eliphakeme njenge-Tri-isobityl phosphate ukuze ahlangabezane nezidingo ezahlukahlukene zamakhasimende ethu. Ukuqonda ukwakheka kanye nezakhiwo zeTibp kuvumela izimboni ukwenza kahle ukusetshenziswa kwalo kwalesi sivumelwano esiguquguqukayo, ukuqinisekisa ukusebenza okungcono nokuphepha emikhiqizweni yabo.
